If No Steam Is Coming From Your
Engine
If you get an engine overheat warning, 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.
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 is
safe to do so, pull off the road, shift to
PARK (P) or NEUTRAL (N) and let the
engine idle.
2) Set the climate controls to the highest
heat setting and fan speed and open
the windows as necessary.If you no longer have the overheat warn-
ing, you can drive. Just to be safe, drive
slower for about 10 minutes. If the warning
does not come back on, you can drive nor-
mally.
If the warning continues and you have not
stopped, pull over, stop, and park your
vehicle right away.
If there is still no sign of steam, you can
idle the engine for three minutes while you
are 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” later in this section.
You may decide not to lift the hood but to
get service help right away.
Overheated Engine Protection Operat-
ing Mode
This emergency operating mode allows
your vehicle to be driven to a safe place in
an emergency situation. If an overheated
engine condition exists, an overheat pro-
tection mode which alternates firing groups
of cylinders helps prevent engine damage.
In this mode, you will notice a significant
loss in power and engine performance.
The engine coolant temperature warning
light on the instrument panel will come on
to indicate the vehicle has entered over-
heated engine protection operating mode.
The temperature gage will also indicate an
overheat condition exists. Drivingextended miles (km) and/or towing a trailer
in the overheat protection mode should be
avoided.
Cooling SystemWhen you decide it is safe to lift the hood,
here is what you will see:
1733770
A. Electric Engine Cooling Fans
B. Coolant Recovery Tank
CAUTION
If your engine catches fire because
you keep driving with no coolant,
your vehicle can be badly damaged.
The costly repairs would not be cov-
ered by your warranty. Refer to
“Overheated Engine Protection Oper-
ating Mode” in this section for infor-
mation on driving to a safe place in
an emergency.
CAUTION
After driving in the overheated
engine protection operating mode, to
avoid engine damage, allow the
engine to cool before attempting any
repair. The engine oil will be severely
degraded. Repair the cause of cool-
ant loss, change the oil and reset the
oil life system. Refer to “Engine Oil”
in this section.
