OPERATION
342
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. Each time the
SET+ switch is pressed momentarily, idle speed will increase
approximately 10 rpm (the speed cannot be increased above the
maximum allowed by the engine manufacturer).
5. The idle speed is adjusted down with the SET- switch. Each time
the SET- switch is pressed momentarily, the idle speed will
decrease approximately 10 rpm (the speed cannot be adjusted
below the low idle set by the engine manufacturer).
6. When the desired engine idle speed is reached, push and hold the
SET and move the cruise control switch to the RESUME position
at the same time and hold them in position for four seconds.
Release the switches.
7. Release the brake pedal to set the new idle speed. If an error was
made during the adjustment procedure, the default idle speed will
be maintained.
Idle Shutdown Timer
The idle shutdown timer can be programmed to shut the engine down
after a specific engine idling time. This programming cannot be
changed by the operator, but can be done using special tools. Contact
your authorized Volvo Truck dealer for details.
The permitted idle time can be set to the following time intervals:
Volvo — 1 to 40 minutes
Cummins — 1 to 100 minutes
