If No Steam Is Coming From Your
Engine
An overheated engine warning can indicate a serious
problem. See Engine Coolant Temperature Warning
Light on page 3-34.
If there is an overheated engine warning, and no steam
is seen or heard, the problem may not be too serious.
Sometimes the engine can get a little too hot when
the vehicles:
•
Climbs a long hill on a hot day.
•
Stops after high-speed driving.
•
Idles for long periods in traffic.
•
Tows a trailer.
If the overheated engine warning appears with no sign
of steam, try this for a minute or so:
1. In heavy traffic, let the engine idle in NEUTRAL (N)
while stopped. If it is safe to do so, pull off the road,
shift to PARK (P) or NEUTRAL (N) and let the
engine idle.
2. Adjust the heater to the highest temperature and
fan speed settings and open the window as
necessary.
If the overheated engine warnings no longer exist, the
vehicle can be driven. Just to be safe, drive slower
for about 10 minutes. If the warning does not come back
on, continue to drive.
If the warning continues, and you have not stopped, pull
over, stop, and park the vehicle right away.
If there is still no sign of steam, idle the engine for three
minutes while parked. If the warning still exists, turn
off the engine and get everyone out of the vehicle until
it cools down. Also, see “Overheated Engine Protection
Operating Mode” listed previously in this section.
You may decide not to lift the hood but to get service
help right away.
