engine is overheated, the liquids
in it can catch fire. Youor others
could be badly burned. Stop the
engine if it overheats, and get out
of the vehicle until the engine
is cool.

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.
.Towsa trailer.
If the overheat warning is displayed
with no sign of steam:
1. Turnthe air conditioning off.
2. Turnthe heater onto the highest
temperature and to the highest
fan speed. Open the windows as
necessary.
3. When it is safe to do so, pull off
the road, shift toP(Park) or
N(Neutral), andlet the
engine idle.
If the temperature overheat gauge 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
and have the cooling system
checked for proper fill and function.
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
