Buick 2009 Enclave - Manual (Page 296)

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
gage indicates an overheat condition
exists. Driving extended distances
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 5-12.
Power Steering Fluid
The power steering fluid reservoir is
located toward the front of the
engine compartment on the
passenger side of the vehicle. See
Engine Compartment Overview
on page 5-10 for reservoir location.
When to Check Power
Steering Fluid
It is not necessary to regularly check
power steering fluid unless you
suspect there is a leak in the system
or you hear an unusual noise. A fluid
loss in this system could indicate a
problem. Have the system inspected
and repaired.
How to Check Power Steering
Fluid
To check the power steering fluid:
1. Turn the key off and let the engine
compartment cool down.
2. Remove engine oil fill cap.
3. Slide engine cover rearward and
lift to remove.
4. Wipe the cap and the top of the
reservoir clean.
5. Unscrew the cap and wipe the
dipstick with a clean rag.
6. Replace the cap and completely
tighten it.
7. Remove the cap again and look at
the fluid level on the dipstick.
