Vehicle Care

If No Steam is Coming from
the Engine Compartment

If an engine overheat warning is
displayed but no steam can be seen
or heard, the problem may not be
too serious. Sometimes the engine
can get a little too hot when the
vehicle:

.

Climbs a long hill on a hot day.

.

Stops after high-speed driving.

.

Idles for long periods in traffic.

.

Tows a trailer.

If the overheat warning is displayed
with no sign of steam:

1. Turn the air off.

2. Turn the heater on to the highest

temperature and to the highest
fan speed. Open the windows as
necessary.

3. In heavy traffic, let the engine

idle in N (Neutral) while stopped.
If it is safe to do so, pull off the
road, shift to P (Park) or
N (Neutral) and let the
engine idle.

If the temperature overheat gauge
is no longer in the overheat zone or
an overheat warning no longer
displays, the vehicle can be driven.
Continue to drive the vehicle slowly
for about 10 minutes. Keep a safe
vehicle distance from the vehicle in
front. If the warning does not come
back on, continue to drive normally.

If the warning continues, pull over,
stop, and park the vehicle
right away.

If there is no sign of steam, idle the
engine for three minutes while
parked. If the warning is still
displayed, turn off the engine until it
cools down. Also, see “Overheated
Engine Protection Operating Mode”
following.

Overheated Engine
Protection
Operating Mode

This emergency operating mode
allows the vehicle to be driven to a
safe place in an emergency

situation. If an overheated engine
condition exists, an overheat
protection mode which alternates
firing groups of cylinders helps
prevent engine damage. In this
mode, a significant loss in power
and engine performance will be
noticed. The temperature gauge will
indicate an overheat condition
exists. Driving extended km (mi)
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 10‑8
