Engine Overheating

The vehicle has an engine coolant
temperature warning light on the
instrument cluster to warn of engine
overheating. See Engine Coolant
Temperature Warning Light 0 96.
If the decision is made not to lift the
hood when this warning appears,
but instead get service help right
away, see Roadside Assistance
Program 0 267.
If the decision is made to lift the
hood, make sure the vehicle is
parked on a level surface.
Then check to see if the engine
cooling fans are running. If the
engine is overheating, the fans
should be running. If they are not,
do not continue to run the engine
and have the vehicle serviced.
See if the engine cooling fan speed
increases when idle speed is
doubled by pushing the accelerator
pedal down. If it does not, the
vehicle needs service. Turn off the
engine.
Caution
Running the engine without
coolant may cause damage or a
fire. Vehicle damage would not be
covered by the vehicle warranty.
If Steam is Coming from the
Engine Compartment
Warning
Steam from an overheated engine
can burn you badly, even if you
just open the hood. Stay away
from the engine if you see or hear
steam coming from it. Just turn it
off and get everyone away from
the vehicle until it cools down.
Wait until there is no sign of
steam or coolant before you open
the hood.
If you keep driving when the
engine is overheated, the liquids
in it can catch fire. You or others
could be badly burned. Stop the
Warning (Continued)
engine if it overheats, and get out
of the vehicle until the engine
is cool.
Overheated Engine
Protection

Operating Mode

The engine has an engine
protection mode to reduce the
chance of damage if the coolant
temperature goes too high (for
example, when climbing steep
grades in high temperature with
heavy loads, such as when towing a
trailer). When the engine
temperature reaches a certain level:
The engine coolant temperature
warning light will illuminate.
Engine power may be reduced.
The air conditioning cooling
function may be automatically
turned OFF for a short time (the
blower will continue to operate).
