vn-vhd.bk Page 272 Tuesday, July 1, 2008 9:44 AM OPERATION Inspection Failure to properly inspect and maintain the safety belts can cause serious personal injury or death. It is critical that any time a vehicle has been involved in an accident, the entire safety belt system must be replaced in the vehicle (which also includes the sleeper bunk restraints) if they were in use at the time of the accident. Failure to replace the safety belt system may result in serious injury or death.
vn-vhd.bk Page 273 Tuesday, July 1, 2008 9:44 AM OPERATION Check the belts, buckles, latch plates, retractors, anchorages, and guide loops to ensure that they are working properly. Look for loose/damaged parts (without disassembling) that could keep the restraint system from working properly. If the safety belt, retractor and hardware were in use during a collision, they must be replaced. The restraint system anchorage fasteners must be replaced if necessary.
vn-vhd.bk Page 274 Tuesday, July 1, 2008 9:44 AM OPERATION The D-loop web guide is an area where almost constant movement of the safety belt webbing occurs because of the relative movement between the seat and the cab. This constant movement forms an area where wear will often occur. The webbing must be closely examined to determine if there are any cuts, fraying or extreme wear in the webbing. Cuts, fraying or excessive wear would indicate the need for replacement of the safety belt system.
vn-vhd.bk Page 275 Tuesday, July 1, 2008 9:44 AM OPERATION Check to make sure that the D-loop web guide is rotating properly. If the guide is not rotating properly, the webbing will pull at the wrong angle through the guide, accelerating wear. If equipped, check the comfort clip for cracks or possible damage. Make sure that it works properly.
vn-vhd.bk Page 276 Tuesday, July 1, 2008 9:44 AM OPERATION Check the buckle by inserting the latch and verifying proper operation. Determine if the latch plate is worn or deformed. Check the buckle and latch casing for cracks or breakage.
vn-vhd.bk Page 277 Tuesday, July 1, 2008 9:44 AM OPERATION The retractor web storage device is mounted on the B-pillar, just behind the door in the cab. The retractor is the heart of the safety belt system and can be damaged if abused, even unintentionally. Check the retractor web storage device operation to ensure that it is not locked and that it spools out and retracts the webbing properly.
vn-vhd.
vn-vhd.bk Page 279 Tuesday, July 1, 2008 9:44 AM OPERATION All hardware for safety belt mounting points should be evaluated for corrosion. All attachment points of the system should be checked for tightness of mounting hardware. Check the web in areas exposed to ultraviolet rays from the sun or extreme dust or dirt. If the original color of the web in these areas is extremely faded, the physical strength of this web may have deteriorated. If this condition exists, replace the safety belt system.
vn-vhd.bk Page 280 Tuesday, July 1, 2008 9:44 AM OPERATION SRS AIRBAG The SRS airbag is intended to supplement — not replace — the standard safety belt. The airbag is not deployed when the truck is hit from behind, from the side or if it rolls over. For best protection, sit in a normal, upright position. Always wear the safety belt. For added safety, the vehicle may be equipped with an airbag or SRS (Supplemental Restraint System) as a supplement to the standard three-point anchored safety belt.
vn-vhd.bk Page 281 Tuesday, July 1, 2008 9:44 AM OPERATION The inflatable airbag is folded into the center of the steering wheel. It inflates in the event of a serious collision above a certain level, where the angle of impact, crash severity, speed and nature of the object involved in the collision all play a part in whether or not the airbag is activated. The system consists of a gas generator surrounded by the inflatable airbag.
vn-vhd.bk Page 282 Tuesday, July 1, 2008 9:44 AM OPERATION If the control unit detects a sufficiently violent deceleration (collision), the system is activated. The gas generator triggers and fills the bag with a nontoxic gas within a few hundredths of a second. During a collision, after the bag is full, gas flows out through two holes in the weave. These holes are large enough to let the airbag collapse slowly, gently catching the driver.
vn-vhd.bk Page 283 Tuesday, July 1, 2008 9:44 AM OPERATION If a problem develops in the system, the CHECK tell-tale will come on together with the SRS tell-tale. Warning Labels The label attached to the left-hand sunvisor shows the year and month when an authorized Volvo Truck dealer should be contacted for a specific inspection and for a possible replacement of the airbag. This is done to guarantee the function of the airbag after the indicated date. Replace the label when replacing the airbag module.
vn-vhd.bk Page 284 Tuesday, July 1, 2008 9:44 AM OPERATION Steering shafts and steering wheel should not be removed, adjusted or replaced without following the proper work procedure. Failure to do so can damage the SRS system, which can result in malfunction of the SRS. A warning label is located on the upper steering shaft. There is also a label on the inside of the windshield that indicates the inclusion of an airbag to the vehicle safety features.
vn-vhd.bk Page 285 Tuesday, July 1, 2008 9:44 AM OPERATION When equipped with an airbag, a label with the correct procedure for protecting small children and protecting the driver is attached to the left-hand, overhead storage lid or back of sunvisor. Any queries concerning the SRS system should be directed to an authorized Volvo Truck dealer. There is no maintenance required for the SRS system until the date on the warning label located on the left-hand sunvisor.
vn-vhd.bk Page 286 Tuesday, July 1, 2008 9:44 AM OPERATION General Information When is the Airbag Deployed? The airbag is only deployed during a head-on collision, where the vehicle hits a fixed or heavy object with sufficient force. The SRS system registers both the force of the collision and the internal forces caused by the collision. The control unit determines if the collision is sufficiently violent for the airbag to be deployed. The SRS system is only activated once in a collision.
vn-vhd.bk Page 287 Tuesday, July 1, 2008 9:44 AM OPERATION When is the Airbag not Deployed? Not all frontal collisions activate the SRS system. In a collision with a soft object (a snow drift or bush for example, or a hard or fixed object at low speed), there is no need for the SRS system to be activated. The airbag is usually not inflated in response to side-on collisions, impacts from the rear or if the vehicle overturns. The extent of damage to the vehicle is no measure of how well the SRS system works.
vn-vhd.bk Page 288 Tuesday, July 1, 2008 9:44 AM OPERATION SEATS, GENERAL Several seats can be used in the vehicles. If the seat installed in the vehicle is not explained in this section, see your authorized Volvo dealer.

Exhaust vapor may be visible during a cold start. If exhaust smoke is visible during engine operation, this indicates a problem with the exhaust aftertreatment system. Take the vehicle to an authorized Volvo Truck dealer immediately. IMMOBILIZER FEATURE Volvo Engines Only The Immobilizer Feature is used to prevent the engine from starting.
vn-vhd.bk Page 299 Tuesday, July 1, 2008 9:44 AM OPERATION When the vehicle is placed in the Immobilizer Mode during the previous key-off, the driver is only able to start the vehicle after entering the correct 3-digit code (PIN Code) into the DID using the stalk switch. The driver will continue to be prompted for the PIN Code until the correct 3-digit code is entered.
vn-vhd.bk Page 300 Tuesday, July 1, 2008 9:44 AM OPERATION If the vehicle has not been placed in the Immobilizer Mode during the previous key-off, the driver will be able to start the vehicle as normal. After the password is entered (at shutdown) “Security Mode Active” is displayed.
vn-vhd.bk Page 301 Tuesday, July 1, 2008 9:44 AM OPERATION CONTROL AWARENESS FEATURE VHD Vehicles and Volvo Engines Only The Control Awareness Feature is a protective mechanism for the Volvo engine and transmission. In addition, it provides a mechanical safety to the existing Power Take-Off (PTO) functionality. 앫 Parameters are set in VCADS.
vn-vhd.bk Page 302 Tuesday, July 1, 2008 9:44 AM OPERATION FUEL ECONOMY DRIVING General The absolute fuel consumption (counted in liters per 100 kilometers or miles per US gallon) is determined by a large number of circumstances which can be related to one of the following main areas: 앫 Build specification and equipment 앫 Service and maintenance 앫 External environment 앫 Driving habits Due to these factors, fuel consumption can vary considerably within what is called “normal fuel consumption.
vn-vhd.bk Page 303 Tuesday, July 1, 2008 9:44 AM OPERATION Tires Heavy duty threaded tires increase rolling resistance considerably. For long haul, choose a smoother, ribbed type tire. Choose a lugged type tire only when the added traction in mud and snow is needed. The number of wheels (axles) has a direct effect on the rolling resistance and, thereby, the fuel consumption. For volume and/or low weight transports, the use of a 4x2 instead of a 6x4 should be considered.
vn-vhd.bk Page 304 Tuesday, July 1, 2008 9:44 AM OPERATION Brakes Dragging brakes increase fuel consumption. They should be checked regularly. It is important that the release action of the air valves is fast and that the moving parts of the wheel brakes are checked for good adjustment and operation. Axles An axle out of alignment increases rolling resistance. Regularly check the front wheel alignment and axles on both the tractor and trailer/semi-trailer.
vn-vhd.bk Page 305 Tuesday, July 1, 2008 9:44 AM OPERATION External Environment Under unfavorable conditions, the external environment can have a negative effect on fuel consumption. This can be broken down into two main groups: weather and wind, and the nature of the roads. Rain, snow, icy conditions and headwinds have a large negative impact on fuel economy, as do hilly roads and uneven road surfaces. Headwinds Headwinds have a large negative impact on fuel consumption.
vn-vhd.bk Page 306 Tuesday, July 1, 2008 9:44 AM OPERATION Driving Habits The way in which a vehicle is being driven is the one factor which has the greatest influence on fuel consumption. Correct driving saves fuel and reduces vehicle wear. To achieve optimal running economy, the driver should always remember to: 앫 Start the engine correctly (especially important in winter season). 앫 Maintain an even and correct speed. 앫 Keep the engine at its optimum speed range.
vn-vhd.bk Page 307 Tuesday, July 1, 2008 9:44 AM OPERATION Air Tanks When draining the air tanks, do not look into the area of the draining air. Dirt or sludge particles may be in the air stream and could cause eye injury. All air tanks on the vehicle should be drained daily. Empty any moisture from air tanks by pulling the drain valve wire or by opening the drain cocks and allowing the air pressure to drain completely. Make sure the drain cocks close properly after draining.
vn-vhd.bk Page 308 Tuesday, July 1, 2008 9:44 AM OPERATION Trucks with automated Meritor Transmission: Drain the transmission air supply tank located on the right-hand rail daily to check for contamination, water, oil, etc. Charging Air to Another Vehicle There are many methods which may be used to charge the air system of another vehicle.

vn-vhd.bk Page 310 Tuesday, July 1, 2008 9:44 AM OPERATION The cruise control cannot be engaged at speeds below approximately 30 km/h (18 mph). Disengaging The cruise control is disengaged if the brake is depressed, or if the cruise control switch is set to OFF. If the ignition key is turned back to the accessories position (I), the cruise control system will automatically be disengaged.
vn-vhd.bk Page 311 Tuesday, July 1, 2008 9:44 AM OPERATION Acceleration Momentary acceleration (such as for passing another vehicle) does not interrupt cruise control operation. After passing, release accelerator and let the vehicle slow to cruise control speed. The previously set speed will then be maintained without having to set the switch to RESUME. On vehicles equipped with Eaton VORAD SmartCruise, cruise control is disengaged in the event the SmartCruise system fails to operate.
vn-vhd.bk Page 312 Tuesday, July 1, 2008 9:44 AM OPERATION BRAKE OPERATION Brake Safety Information DO NOT inspect or adjust parts or components in the brake system without setting the parking brake, placing the transmission in neutral and securely chocking the wheels. If the vehicle is not secured to prevent uncontrolled vehicle movement, it could roll and cause severe personal injury or death.
vn-vhd.bk Page 313 Tuesday, July 1, 2008 9:44 AM OPERATION DO NOT operate the vehicle when there is a malfunction in the compressed air system. An air brake system with leaks or other malfunctions may prevent the brake system from operating properly. The vehicle should not be operated until the system is repaired and all brake circuits are working properly. Failure to repair the system can lead to loss of control of the vehicle resulting in severe personal injury or death.
vn-vhd.bk Page 314 Tuesday, July 1, 2008 9:44 AM OPERATION Automatic slack adjusters MUST NOT be manually adjusted in an effort to correct excessive push rod stroke, as this condition indicates that a problem exists with the automatic adjuster, installation of the automatic slack adjuster or problems related to components of the foundation brakes. These conditions will not be corrected by manually adjusting the automatic slack adjusters.
vn-vhd.bk Page 315 Tuesday, July 1, 2008 9:44 AM OPERATION Never release or drive a truck that has a brake discrepancy — no matter how minor — until it has been repaired or corrected. Failure to repair brake discrepancies can result in compromised brake efficiency and may lead to loss of control of the vehicle resulting in severe personal injury or death. Air pressures in the two circuits are monitored by two pressure gauges on the right side of the instrument cluster.
vn-vhd.bk Page 316 Tuesday, July 1, 2008 9:44 AM OPERATION Gauge 1 and Gauge 2 1. Gauge 1 2. Gauge 2 Before operating the vehicle, check the air gauges which indicate air pressure. They should not register less than 420 kPa (65 psi).
vn-vhd.bk Page 317 Tuesday, July 1, 2008 9:44 AM OPERATION Both circuits are piped into a dual brake valve, which simultaneously applies front and rear axle service brakes during each brake application. In the event of a failure in either one of the circuits, the other circuit becomes the emergency circuit for applying the brakes. 1. Clutch Fluid Reservoir 2. Windshield Washer Fluid Fill 3. Brake Valve The Master Warning Tell-Tale and buzzer alerts of a dangerous situation.
vn-vhd.bk Page 318 Tuesday, July 1, 2008 9:44 AM OPERATION Master Warning Tell-Tale An important feature of the brake system is that an automatic spring brake application does not take place as a result of an air loss in only one of the two circuits. In this case, brake control remains in the foot brake valve. In each air pressure gauge, there is a warning light connected to a low pressure switch that comes on if air pressure goes below 420 kPa (60 psi).
vn-vhd.bk Page 319 Tuesday, July 1, 2008 9:44 AM OPERATION Foot Brake Valve The foot brake valve is directly connected to the brake pedal. The valve gives a progressive output against the pedal travel. This allows better control of the pressure in the first half of the pedal travel. In the last half of the pedal travel, the pressure output increase is faster. The foot brake valve applies the service brakes, incorporating both the primary and secondary air systems.
vn-vhd.bk Page 320 Tuesday, July 1, 2008 9:44 AM OPERATION 1. The best possible stop will be made when the first brake application is as firm as the speed and road condition permit. Then, ease off as the speed is reduced. Never apply the brakes lightly at first and increase the pressure as the speed diminishes. 2. DO NOT fan the brake pedal. Fanning gives poor brake performance and wastes air. 3.
vn-vhd.bk Page 321 Tuesday, July 1, 2008 9:44 AM OPERATION Parking Brake/Trailer Supply Valves Trucks/Tractors may have two air control valves on the instrument panel: 앫 Trailer Supply (red octagonal knob) 앫 System Park (yellow diamond knob) The System Park valve knob (yellow) should be pushed in first, after sufficient air pressure is built up (apply foot brake to prevent vehicle from rolling). The Trailer Air Supply valve knob may then be pushed in.
vn-vhd.bk Page 322 Tuesday, July 1, 2008 9:44 AM OPERATION On vehicles equipped with the standard two valve system, the operation of one valve together with the other permits the operator to select the desired functions described below: Red Valve (Trailer Air Supply) Yellow Valve (System Park) Function (Mode) Out Out System Park In Out Trailer Charge In In Normal Running Out In Bobtail Parking Brake Release VN and VHD models have engines equipped with engine electronic control units (EECU).
vn-vhd.bk Page 323 Tuesday, July 1, 2008 9:44 AM OPERATION There is also an engine shut-down device in the EECU that shuts down the engine after a pre-programmed time in order to save fuel. This is activated when the yellow parking brake knob is pulled out. Therefore, some drivers park and release the parking brakes using only the red knob to keep the engine running. It is then easily overlooked that in a vehicle parked with both the yellow and red knobs activated, only the red knob is pushed in by habit.
vn-vhd.bk Page 324 Tuesday, July 1, 2008 9:44 AM OPERATION Spring Brake for Parking Never leave the vehicle without being certain the parking brakes are set or that other precautions are taken to prevent the vehicle from rolling. Failure to do so can result in serious personal injury or death. Before working on or inspecting a vehicle, set the parking brakes, place the transmission in neutral and block the wheels.
vn-vhd.bk Page 325 Tuesday, July 1, 2008 9:44 AM OPERATION The parking brake spring tension is sufficient to hold a fully loaded vehicle on maximum grades permitted on modern highways, provided the brake drums and linings are in good condition and the brakes are properly adjusted. DO NOT use the spring parking brakes if the service brakes are hot, such as after descending a steep grade. Also, do not use the spring parking brakes during freezing temperatures if the wheel brakes are wet.
vn-vhd.bk Page 326 Tuesday, July 1, 2008 9:44 AM OPERATION There are several ways to determine if the parking brakes have been set. By pulling out the yellow knob: 앫 An audible rush of air will be heard when the parking brake knob is pulled. The air exhausts from the park brake valve itself and from the spring brake chambers on the rear axle(s). 앫 A black ring around the base of the yellow control knob will be seen. 앫 The engine will stall if an attempt is made to set the vehicle in motion.
vn-vhd.bk Page 327 Tuesday, July 1, 2008 9:44 AM OPERATION Trailer Brake Hand Control The trailer hand brake control is not a parking brake valve and must not be used as one. This brake is not designed to hold the vehicle stationary. Failure to follow these instructions can result in the unintentional movement of the vehicle and may cause personal injury or death. DO NOT use the trailer brake hand control as a parking brake.
vn-vhd.bk Page 328 Tuesday, July 1, 2008 9:44 AM OPERATION The “121” Brake Standard This manual refers occasionally to “121” brakes. Although some operators believe “121” only applies to vehicles equipped with anti-lock devices, the “121” standard applies to all vehicles that are capable of on-highway operation. The “121” is a Federal requirement also covering alterations or changes to parts or systems related to the “121” standard once the vehicle has been placed in service.
vn-vhd.bk Page 329 Tuesday, July 1, 2008 9:44 AM OPERATION ANTI-LOCK BRAKING SYSTEM (ABS) The vehicle has a standard brake system, equipped with an electronic speed monitoring and control system, Anti-lock Braking System (ABS). ABS monitors wheel speed continuously but is not involved in controlling the wheel speed unless there is an emergency. In normal braking applications, the standard air brake system is in effect. For proper ABS operation, DO NOT change tire sizes.
vn-vhd.bk Page 330 Tuesday, July 1, 2008 9:44 AM OPERATION The ABS control unit contains a self-testing program that is engaged each time the ignition is turned on. The operator can verify the testing by listening for the ABS modulator valves actuating twice in series. To increase the sound, hold down the foot brake pedal when the ignition is turned on.
vn-vhd.bk Page 331 Tuesday, July 1, 2008 9:44 AM OPERATION VOLVO ENHANCED STABILITY TECHNOLOGY Some vehicles are equipped with Volvo Enhanced Stability Technology (VEST). VEST is an advanced stability control system designed to provide both roll stability and under- and over-steer correction in a wide variety of driving conditions.
vn-vhd.bk Page 332 Tuesday, July 1, 2008 9:44 AM OPERATION The TCS includes a switch to turn off the function. When the switch is in the OFF position, the TCS operates normally to increase traction if the drive wheels begin spinning. When the switch is pressed once, the TCS tell-tale in the instrument cluster blinks continuously, indicating that the TCS is in mud/snow mode.
vn-vhd.bk Page 333 Tuesday, July 1, 2008 9:44 AM OPERATION VEHICLE SPEED RETARDING DEVICES When operating a tractor bobtail (without a trailer) or on slippery roads, the engine brake switch must be in the “OFF” position. Failure to follow this instruction can result in loss of vehicle control and serious personal injury or death.
vn-vhd.bk Page 334 Tuesday, July 1, 2008 9:44 AM OPERATION Volvo Variable Geometry Turbo Brake The variable geometry turbo brake is standard with the Volvo 11F and 13F engine. It uses software to close the variable geometry turbocharger to create retardation. For both variable geometry turbocharger and engine brakes, use a “one gear” driving strategy when going downhill to keep engine speed up for effective braking (for example: uphill in 7th gear and downhill in 6th).
vn-vhd.bk Page 335 Tuesday, July 1, 2008 9:44 AM OPERATION The retarder is automatically disabled when the ABS (anti-lock brake system) is active. The Transmission Retarder is an option with Allison HD and MD transmissions. It is activated by an on/off switch in the auxiliary panel and is controlled by a stalk switch mounted in front of the wiper switch. You can set 6 different levels with the stalk switch.
vn-vhd.bk Page 336 Tuesday, July 1, 2008 9:44 AM OPERATION Vehicle brake lights are always on when transmission retarder is active. For complete warnings and instructions, refer to the Allison Transmission manual. STARTING THE ENGINE Start Procedure For cold weather starting, see “COLD WEATHER OPERATION” on page 347. These starting and operating procedures should be followed for all engines.
vn-vhd.bk Page 337 Tuesday, July 1, 2008 9:44 AM OPERATION Never operate the starter without first placing the transmission in neutral or depressing the clutch pedal. Failure to follow these instructions may result in the unintentional movement of the vehicle resulting in property damage, personal injury or death. 1. Before starting the engine, perform the engine pre-trip inspection and daily maintenance checks in “PRE-TRIP INSPECTION AND DAILY MAINTENANCE” on page 220. 2.
vn-vhd.bk Page 338 Tuesday, July 1, 2008 9:44 AM OPERATION 3. Place the transmission in neutral or depress the clutch pedal. DO NOT crank the engine for more than 30 seconds at a time; wait two minutes after each try to allow the starter to cool. Failure to follow these instructions could cause starter damage. Some starters are equipped with starter protection.
vn-vhd.bk Page 339 Tuesday, July 1, 2008 9:44 AM OPERATION 6. When the engine has started, it takes a while to send lubricating oil to all bearings and shafts, and between pistons and liners. Wait for the oil pressure gauge to settle at a normal level, then bring engine speed up gradually. Increase speed as it warms up. Check all gauges during warm-up. 7. During warm-up, apply load gradually until the oil temperature reaches 60°C (140°F).
vn-vhd.bk Page 340 Tuesday, July 1, 2008 9:44 AM OPERATION Engine Overspeed This vehicle is equipped with a diesel engine and should not be operated in an area with a concentration of hydrocarbon vapors (for example gasoline or diesel fuel fumes). Be especially cautious of low-lying or closed-in areas. The vapors may be drawn into the engine through the air intake and cause the engine to overspeed. Hot carbon and other sparks may come from the exhaust system, and cause an explosion and fire.
vn-vhd.bk Page 341 Tuesday, July 1, 2008 9:44 AM OPERATION Avoid excessive idling. If the vehicle is parked for more than 5 minutes, stop the engine. An engine can burn from 3 to 5.5 liters (0.75 to 1.5 gallons) of fuel per hour while idling. During long engine idling periods, the engine coolant temperature may fall below the normal operating range.
vn-vhd.bk Page 342 Tuesday, July 1, 2008 9:44 AM OPERATION 1. Set the cruise control switch to the ON position. 2. Depress the foot brake pedal. Hold it down during the entire procedure. 3. Move the cruise control switch to the RESUME position and hold it there for four seconds. Release the switch. The engine speed will drop to the default low idle (Volvo engines), or a slight drop in idle speed will occur (Cummins). 4. The idle speed is adjusted up with the SET+ switch.
vn-vhd.bk Page 343 Tuesday, July 1, 2008 9:44 AM OPERATION When the idle shutdown feature is enabled, the engine will typically shut down at the set time under the following conditions: 앫 Vehicle speed is 0. 앫 Engine is running at idle speed. 앫 Coolant temperature is above 45°C (113°F). 앫 Parking brake is applied (Volvo engines only). These are standard choices when the vehicle is delivered. For more information about other customer adaptation choices, contact your authorized Volvo Truck dealer.
vn-vhd.bk Page 344 Tuesday, July 1, 2008 9:44 AM OPERATION Downhill Operation DO NOT exceed engine manufacturer's recommended maximum engine speed. Engine damage can occur. If equipped with an engine or exhaust brake, DO NOT exceed 2300 rpm. On a downgrade, do not coast with the clutch pedal depressed or the transmission in neutral. Select a gear that does not allow the engine speed to exceed the engine manufacturer's maximum engine speed recommendation.
vn-vhd.bk Page 345 Tuesday, July 1, 2008 9:44 AM OPERATION Stopping the Engine Allow the engine to slow down and idle for 3 to 5 minutes before shutting it off. This allows the turbo to slow down and the cooling system to dissipate the engine heat. Switch the engine off by turning the ignition key to the B, or OFF, position. Shutting off an engine immediately after high speed or full load operation can damage the turbo and cause heat stress in the engine.
vn-vhd.bk Page 346 Tuesday, July 1, 2008 9:44 AM OPERATION The engine shut-down system will automatically derate or stop the engine when one or more of the systems listed below reaches a critical stage: 앫 High Coolant Temperature 앫 Low Oil Pressure 앫 Low Coolant Level 앫 High Crankcase Pressure 앫 High Diesel Particulate Filter Soot Level Derate and shut-down functions may be applied differently, or added to, depending on the engine manufacturer.
vn-vhd.bk Page 347 Tuesday, July 1, 2008 9:44 AM OPERATION COLD WEATHER OPERATION Volvo Engine Cold Start These cold start instructions are for Volvo engines only. For other engine makes, see the manufacturer's handbook. DO NOT use ether or other combustible starting aids on any Volvo engine. Introduction of ether or similar starting aids could cause a fire or explosion resulting in severe property damage, serious personal injury or death. Volvo engines have a unique cold start feature.
vn-vhd.bk Page 348 Tuesday, July 1, 2008 9:44 AM OPERATION If necessary, once the engine has started, the preheater will reengage (post heating) for the same length of time as the preheat time. Engines Without Preheater Engines not equipped with a preheater may, depending on coolant temperature, take longer to start. If this should happen, DO NOT release the ignition key until the engine has started (while still observing the 30 second maximum cranking time).
vn-vhd.bk Page 349 Tuesday, July 1, 2008 9:44 AM OPERATION Cold Weather Operation If the engine is in good mechanical condition and the necessary preparations are taken for cold weather operation, ordinary cold weather will not cause difficulty in starting or loss of efficiency. Cold weather operation does require changes in operating practices, maintenance procedures, lubrication and fuel. Additions to the vehicle, such as heated fuel filters, fuel tank heater, engine block heater, winterfront, etc.
vn-vhd.bk Page 350 Tuesday, July 1, 2008 9:44 AM OPERATION For cold weather operation, follow these recommendations: 앫 When starting the engine in temperatures below –15°C (5°F), use engine lubricants of lower viscosity. See the Operator's Manual Vehicle Maintenance for additional information. 앫 When the temperature is below freezing, make sure the concentration of antifreeze in the coolant is sufficient to prevent freezing. Refer to the Operator's Manual Vehicle Maintenance for additional information.
vn-vhd.bk Page 351 Tuesday, July 1, 2008 9:44 AM OPERATION Engine Block Heater (Optional) An electric engine block heater can be installed for keeping the coolant hot when the vehicle is parked. The heater is mounted through the side of the engine block with the heater coils in the coolant jacket. The heater does not interfere with normal operation and can be permanently installed. The heater runs on 120 V and has an easily accessible plug, located beside the driver side door.
vn-vhd.bk Page 352 Tuesday, July 1, 2008 9:44 AM OPERATION Oil Pan Heater (Optional) Oil pan heaters aid low temperature starting by improving oil flow to critical parts in the engine. This helps prevent engine wear. They are similar to block heaters and are wired into the same plug as the engine coolant heater. Fuel Heater Filter (Optional) If running in very cold weather, a heated fuel filter should be added. A number of different fuel heaters are available as options.
vn-vhd.bk Page 353 Tuesday, July 1, 2008 9:44 AM OPERATION Fuel Tank Heater (Optional) An in-tank fuel heater is also available. In-tank heaters use hot engine coolant to warm the fuel. This prevents wax formation in the fuel during cold season operation. These heaters are thermostatically controlled and will automatically raise the fuel temperature to an optimum level.
vn-vhd.bk Page 354 Tuesday, July 1, 2008 9:44 AM OPERATION Please see your authorized Volvo Truck dealer for Volvo recommended winterfronts. If there is engine or related damage that can be traced to an improperly used winterfront, the warranty is no longer valid for those parts.
