Engine Brake
The engine brake is enabled by a dash-mounted ON/OFF Switch with a separate
intensity switch to select low, medium, or high braking power.
CAUTION: LOSS OF VEHICLE CONTROL
To avoid injury from loss of vehicle control, do not activate the
Engine Brake system under the following conditions:
On wet or slippery pavement, unless the vehicle is equipped
with ABS (anti-lock braking system) and you have had prior
experience driving under these conditions.
When driving without a trailer (bobtailing) or pulling an empty
trailer.
If the tractor drive wheels begin to lock or there is fishtail
motion after the Engine Brake is activated, deactivate the brake
system immediately if this occurs.
The engine brake will only operate when the Accelerator Pedal is fully released.
Disengaging the clutch will prevent the engine brake from operating.
The engine brake will supply braking power even when in Cruise Control. The
Motor Control Module will control the amount of engine braking with respect to
the Cruise Control set speed. The maximum amount of braking (low, medium,
high) is selected with the dash or steering wheel switches.
Engine Protection
The electronic engine control protection system monitors all engine sensors,
electronic components, and recognizes system malfunctions. If a critical fault is
detected, the AWL (Check Engine) and RSL (Stop Engine) illuminate. The
malfunction codes are logged into the MCM's memory.
