Chevrolet Kodiak 2008, Owner'S Manual

Page: 87 / 384

This system can be used to increase your engine idle
speed whenever the following conditions are met:
•
The brake pedal is not pressed.
•
The vehicle is at a complete stop for vehicles with
diesel engines. The vehicle must not be moving
and the accelerator must not be pressed for vehicles
with gasoline engines.
•
If the vehicle has manual transmission the clutch
pedal is not pressed or, if the vehicle has the
automatic transmission it is in NEUTRAL (N) or
PARK (P).
The manual high idle feature is activated by pressing
the switch on the instrument panel. When the switch is
pressed again, or any of the previous conditions are
not met, manual high idle will be deactivated.
The manual high idle has been preset at the factory.
Your dealer may change the setting to fit your needs.
For vehicles with Caterpillar
®
diesel engines, the
high idle switch can be used to set any desired high
idle speed.
To set a new temporary engine idle speed do the
following:
1. Make sure all of the previously described conditions
are met.
2. Press the accelerator pedal to the desired engine
speed.
3. Momentarily press the manual high idle switch.
The temporary high idle speed will be set. This new high
idle rpm level will be remembered by the system until
either the ignition is turned to OFF or a new high
idle speed is set.
Automatic High Idle System
The automatic high idle feature will engage whenever
you start your vehicle and the engine is below the preset
operating temperature. This will help decrease engine
warm-up time.
On vehicles that have the Caterpillar
®
diesel engine you
may have an exhaust restrictor that will operate in
High Idle mode. The exhaust brake switch must be on
for this feature to operate. See Diesel Engine Exhaust
Brake on page 2-26 for more information.
Idle speed will then return to normal when the engine
reaches the preset operating temperature or has
been operating for at least 10 minutes.
