If you do decide 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, both fans
should be running. If they are
not, do not continue to run the
engine and have the vehicle
serviced.
Notice:Engine damage from
running the engine without
coolant is not covered by the
warranty.
Notice:If the engine catches re
while driving with no coolant,
the vehicle can be badly
damaged. The costly repairs
would not be covered by
the vehicle warranty. See
Overheated Engine Protection
Operating Mode on page 5-22for
information on driving to a
safe place in an emergency.If Steam Is Coming From The
Engine Compartment
{CAUTION
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. 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
vehicles engine is overheated, the
liquids in it can catch re. You or
others could be badly burned.
Stop the engine if it overheats,
and get out of the vehicle until the
engine is cool.
SeeOverheated Engine Protection
Operating Mode on page 5-22for
information on driving to a safe
place in an emergency.
If No Steam Is Coming From
The Engine Compartment
If an engine overheat warning is
displayed but no steam can be seen
or heard, the problem may not be too
serious. Sometimes the engine can
get a little too hot when the vehicle:
Climbs a long hill on a hot day.
Stops after high-speed driving.
Idles for long periods in traffic.
Tows a trailer.
If the overheat warning is displayed
with no sign of steam:
1. Turn the air conditioning off.
2. Turn the heater on to the highest
temperature and to the highest
fan speed. Open the windows as
necessary.
3. If in a traffic jam, shift to
N (Neutral), otherwise, shift
to the highest gear while
driving—D(Drive) or L (Low).
Service and Appearance Care 5-21

If the temperature overheat gage is
no longer in the overheat zone or an
overheat warning no longer displays,
the vehicle can be driven. Continue
to drive the vehicle slow for about
10 minutes. Keep a safe vehicle
distance from the car in front of you.
If the warning does not come back
on, continue to drive normally.
If the warning continues, pull over,
stop, and park the vehicle right away.
If there is no sign of steam, idle the
engine for three minutes while
parked. If the warning is still
displayed, turn off the engine until it
cools down. Also, see “Overheated
Engine Protection Operating
Mode” next in this section.Overheated Engine
Protection
Operating Mode
This emergency operating mode lets
the vehicle be driven to a safe place
in an emergency situation. If an
overheated engine condition exists,
an overheat protection mode which
alternates ring groups of cylinders
helps prevent engine damage. In this
mode, there is a signicant loss in
power and engine performance. The
temperature gage indicates an
overheat condition exists. Driving
extended distances and/or towing a
trailer in the overheat protection
mode should be avoided.Notice:After driving in the
overheated engine protection
operating mode, to avoid engine
damage, allow the engine to
cool before attempting any repair.
The engine oil will be severely
degraded. Repair the cause
of coolant loss, change the oil
and reset the oil life system. See
Engine Oil on page 5-11.
Power Steering Fluid
The power steering uid reservoir is
located toward the front of the engine
compartment on the passenger
side of the vehicle. SeeEngine
Compartment Overview on
page 5-10for reservoir location.
