2009 GMC ACADIA towing

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 ring groups of cylinders
helps prevent engine damage. In this
mode, there is a signicant 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.
SeeEngine Oil on page 5-11.
Power Steering Fluid
The power steering uid reservoir
is located toward the front of the
engine compartment on the
passenger side of the vehicle.
SeeEngine Compartment Overview
on page 5-10for reservoir location.
When to Check Power
Steering Fluid
It is not necessary to regularly
check power steering uid unless
you suspect there is a leak in
the system or you hear an unusual
noise. A uid 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 uid:
1. Turn the key off and let the
engine compartment cool down.
2. Remove engine oil ll 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 uid level on the dipstick.
The uid level should be somewhere
between MAX and MIN line on the
dipstick in room temperature. If the
uid is on or below MIN line, you
should add uid close to MAX Line.
Service and Appearance Care 5-23

(e)Make sure the safety belt
reminder light and safety belt
assemblies are working properly.
Look for any other loose or damaged
safety belt system parts. If you see
anything that might keep a safety belt
system from doing its job, have it
repaired. Have any torn or frayed
safety belts replaced. Also see
Checking the Restraint Systems on
page 1-61.
(f)Lubricate all key lock cylinders,
hood latch assemblies, secondary
latches, pivots, spring anchor and
release pawl, hood and door hinges,
rear folding seats, and liftgate
hinges. More frequent lubrication
may be required when exposed to a
corrosive environment. Applying
silicone grease on weatherstrips with
a clean cloth will make them last
longer, seal better, and not stick or
squeak.
(g)A fluid loss in any vehicle
system could indicate a problem.
Have the system inspected
and repaired and the fluid level
checked. Add fluid if needed.(h)Change automatic transmission

conditions:

outside temperature regularly

In hilly or mountainous terrain.
When doing frequent trailer
towing.
Uses such as found in taxi,
police, or delivery service.
(i)Drain, flush, and refill cooling
system. This service can be
complex; you should have your
dealer/retailer perform this service.
See Engine Coolant on page 5-17 for
what to use. Inspect hoses. Clean
radiator, condenser, pressure cap,
and filler neck. Pressure test the
cooling system and pressure cap.
(j)Check system for interference or
binding and for damaged or missing
parts. Replace parts as needed.
Replace any components that havehigh effort or excessive wear. Do not
lubricate accelerator or cruise control
cables.
(k)Visually inspect belt for fraying,
excessive cracks, or obvious
damage. Replace belt if necessary.
(l)If driving regularly under dusty
conditions, inspect the filter at each
engine oil change.
(m)Change transfer case fluid if the
vehicle is mainly driven under
one or more of these conditions:
In heavy city traffic where
the outside temperature regularly
reaches 90°F (32°C) or higher.

Customer Assistance Information 7-7

If a Crash Occurs
Here is what to do if you are
involved in a crash.
Check to make sure that you are
all right. If you are uninjured,
make sure that no one else in
your vehicle, or the other vehicle,
is injured.
If there has been an injury, call
emergency services for help. Do
not leave the scene of a crash
until all matters have been taken
care of. Move your vehicle only if
its position puts you in danger or
you are instructed to move it by a
police officer.
Give only the necessary and
requested information to police
and other parties involved in the
crash. Do not discuss your
personal condition, mental frame
of mind, or anything unrelated to
the crash. This will help guard
against post-crash legal action.
If you need roadside assistance,
call GM Roadside Assistance.
SeeRoadside Assistance
Program on page 7-6for more
information.
If your vehicle cannot be driven,
know where the towing service
will be taking it. Get a card from
the tow truck operator or write
down the driver’s name, the
service’s name, and the phone
number.
Remove any valuables from your
vehicle before it is towed away.
Make sure this includes your
insurance information and
registration if you keep these
items in your vehicle.
Gather the important information
you will need from the other
driver. Things like name, address,
phone number, driver’s license
number, vehicle license plate,
vehicle make, model and model
year, Vehicle Identication
Number (VIN), insurance
company and policy number, and
a general description of the
damage to the other vehicle.
If possible, call your insurance
company from the scene of the
crash. They will walk you through
the information they will need. If
they ask for a police report, phone
or go to the police department
headquarters the next day and
you can get a copy of the report
for a nominal fee. In some
states/provinces with “no fault”
insurance laws, a report may not
be necessary. This is especially
true if there are no injuries and
both vehicles are driveable.
