Overheated Engine Protection; Operating Mode - Chevrolet Malibu 2012 Owner's Manual

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

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.
Vehicle Care
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 10.
