Overheated Engine Protection; Operating Mode; Power Steering Fluid - Buick 2010 Enclave Owner's Manual

If the overheat warning is displayed
with no sign of steam:
1. Turn the air conditioning off.
2. Turn the heater on to the highest
temperature and to the highest
fan speed. Open the windows as
necessary.
3. If in a traffic jam, shift to
N (Neutral), otherwise, shift
to the highest gear while
driving D (Drive) or L (Low).
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 slow
for about 10 minutes. Keep a safe
vehicle distance from the car in front
of you. 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
next in this section.
Overheated Engine
Protection

Operating Mode

This emergency operating mode lets
the vehicle 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, there is a significant
loss in power and engine
performance. The temperature
gauge indicates an overheat
condition exists. Driving extended
distances and/or towing a trailer
in the overheat protection mode
should be avoided.
Vehicle Care
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.

Power Steering Fluid

The power steering fluid reservoir is
located under the engine cover on
the passenger side of the vehicle.
See Engine Compartment Overview
on page 10 6 for reservoir location.
