The high idle speed will be temporarily interrupted
and the engine speed will return to normal if any of
the following conditions occur:
•The brake pedal is applied.
•The accelerator pedal is pressed.
•The automatic transmission is shifted out of
PARK (P) or NEUTRAL (N).
•The clutch pedal on the manual transmission is
pressed (pickup models).
•Vehicle speed is detected.
Once these inputs are removed, the engine idle speed
will slowly ramp back up to high idle after the normal
delay, if the conditions for engine coolant temperature
and air intake temperature are still met.
Manual High Idle System

feature, the manual high
idle switch is located
on the instrument panel.
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 speed is below about 5 mph (8 km/h).
•The transmission 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.

Wait to Start Light
Your diesel engine has a
glow plug system to aid in
starting your vehicle.
For pickup models, this light shows that the system is
functioning properly and tells you when the engine is
ready to be started. For van models, an instrument panel
WAIT TO START indicator light shows that the system
is functioning properly and tells you when the engine is
ready to be started.
Your vehicle has a fast warm-up glow plug system. The
wait to start light will illuminate for a considerably shorter
time than most diesel engines due to the rapid heating of
the glow plug system.
For more information, seeStarting the Diesel Engine
on page 2-2.
Reduced Engine Power Light

Adding Coolant
If you need more coolant, add the proper DEX-COOL®
coolant mixtureat the coolant recovery tank, but be
careful not to spill it.
{CAUTION:
You can be burned if you spill coolant on hot
components in the engine compartment.
Coolant contains ethylene glycol, and it will
burn if the engine parts are hot enough. Do not
spill coolant on a hot engine or components in
the engine compartment.
When replacing the pressure cap, make sure it is
hand-tight.
Radiator Pressure Cap
The radiator pressure cap must be tightly installed.
Notice:If the pressure cap is not tightly installed,
coolant loss and possible engine damage may
occur. Be sure the cap is properly and tightly
secured.
Coolant Surge Tank Pressure Cap
The surge tank pressure
cap must be tightly
installed.
Notice:If the pressure cap is not tightly installed,
coolant loss and possible engine damage may
occur. Be sure the cap is properly and tightly
secured.
