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 off.

2. Turn the heater on to the highest temperature and

to the highest fan speed. Open the windows as

necessary.

3. In heavy traffic, let the engine idle in N (Neutral)

while stopped. If it is safe to do so, pull off the

road, shift to P (Park) or N (Neutral) and let

the engine idle.

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’’

later in this section.
