An overheat warning, along with a low coolant message,
can indicate a serious problem. See DIC Warnings
and Messages on page 3-52.
If you get an engine overheat warning with no low
coolant message, but see or hear no steam, the problem
may not be too serious. Sometimes the engine can
get a little too hot when you:
*
Climb a long hill on a hot day.
e
Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning 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 safe to do so, pull of the road,
engine idle.

2. Set the tempe~ture cnntm! tn the highest heat
setting and open the windows, as necessary.
If you no longer have the overheat warning, you can
drive. Just to be safe, drive slower for about 10 minutes.
If the warning doesn't come back on, you can drive
normally,
If the warning continues, pull over, stop, and park your
vehicle right away.
If there's still no sign of steam, idle the engine for three
minutes while you're parked. If you still have the
warning, 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.
