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. Turn on your heater to full hot at the highest

fan speed 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 does not come
back on, you can drive normally.

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.

You may decide not to lift the hood but to get
service help right away.

Overheated Engine Protection
Operating Mode

If an overheated engine condition exists and the
message ENGINE OVERHEATED STOP ENGINE
is displayed, an overheat protection mode which
alternates firing groups of cylinders helps
prevent engine damage. In this mode, you will
notice a loss in power and engine performance.
This operating mode allows your vehicle to
be driven to a safe place in an emergency. Driving
extended miles (km) and/or towing a trailer in
the overheat protection mode should be avoided.

Notice:

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 coolant
loss, change the oil and reset the oil life
system. See

Engine Oil on page 337
