ENGINE IDLE SHUTDOWN (IF EQUIPPED)
Your vehicle may be equipped with an Engine Idle Shutdown system.
This system will automatically shut down your engine when it has been
idling in P (Park) or N (Neutral) for five minutes (parking brake set) or
15 minutes (parking brake not set). During the engine idle shutdown
process:
•TheService Engine Soonlight will flash, once per second, for the
final 30 seconds just prior to shutdown.
•Within the final 30 seconds, the timer can be reset by:
1. changing the position of the accelerator pedal, or
2. changing the brake pedal, clutch pedal, or park brake from engaged
to disengaged or from disengaged to engaged.
•When the timer reaches zero, the engine will shut down.
•In this event, the key remains in the ON (Run) position, and power
continues to be supplied to the accessories.
Battery power may be drained if the key is left in the ON (Run)
position without the engine running.
Note:The engine idle shutdown timer will not start if:
•The engine is operating in power take-off (PTO) mode.
•The engine coolant temperature is below 60° F (16° C).
•The exhaust emission control system is regenerating the diesel
particulate filter (DPF).
Driving
Periodically check the air pressure
gauge while driving. Pressure should
range between approximately
100–125 psi (690–862 kPa). The air
compressor governor cut-in and
cut-out pressure settings are preset
at the factory and are not
adjustable.
When air pressure is insufficient
(below 60 psi [414 kPa]), a warning
light illuminates and a buzzer
sounds when the ignition is in the
ON position.
This condition may be caused by excessive brake applications depleting
the system air pressure. If this condition occurs, stop driving the vehicle
until the compressor has fully recharged the air system.
Do not move the vehicle when the air pressure is insufficient
because the brake system may be inoperative.
Select a gear ratio to help slow your vehicle before descending grades.
Supplement with brakes as required to safely slow the vehicle and avoid
overspeeding the engine.
Air chamber stroke indication
Air chamber push rods have orange stroke indicator markers that warn
when the braking system requires adjustment or repair. The orange
stripe is painted on the air chamber push rod at the slack adjuster stroke
dimension which requires service when visible during brake application.
Air brake inspection and adjustment or repairs should be performed by a
qualified service technician in accordance with the instructions in the
service manual.
