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
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 112 for
more information.
Idle speed will then return to normal under any of
the following conditions:
•
The engine reaches the preset operating
temperature or has been operating for at least
10 minutes.
•
The brake pedal is pressed.
•
The manual transmission clutch pedal is
pressed or, if the vehicle has automatic
transmission, it is shifted from NEUTRAL (N)
or PARK (P).
•
The vehicle speed exceeds about 5 mph
(8 km/h).
•
The throttle is pressed.
