NOTICE:
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not
be covered by your warranty. See “Overheated
Engine Protection Operating Mode” in the
Index for information on driving to a safe place
in an emergency.
If No Steam Is Coming From Your Engine
An overheat warning, along with a low coolant message,
can indicate a serious problem. See “Low Coolant
Message” in the Index.
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:
D Climb a long hill on a hot day.
D Stop after high
-
speed driving.
D Idle for long periods in traffic.
D Tow a trailer. See “Driving on Grades” in the Index.
If you get the overheat warning with no sign of steam,
try this for a minute or so:
1. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
2. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
--
DRIVE (D).
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, push down the
accelerator until the engine speed is about twice as
fast as normal idle speed for at least 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.
