Trailer Wiring Harness
Your vehicle is equipped with a seven-wire trailer
towing harness. This harness has a seven-pin
universal heavy-duty trailer connector (if equipped
with the trailering package) that is attached to a
bracket on the hitch platform. If your vehicle is not
equipped with the heavy-duty trailer connector,
you may purchase one from your dealer.The seven-wire harness contains the following
trailer circuits:
Yellow: Left Stop/Turn Signal
Dark Green: Right Stop/Turn Signal
Brown: Running Lamps
White: Ground
Light Green: Back-up Lamps
Dark Blue: Electric Brakes
Red: Battery Feed (The chassis wiring ring
terminal must be fastened to a stud on the
underhood electrical center before the
trailer feed will become active.)
If you need to tow a light-duty trailer with a standard
four-way round pin connector, an adapter connector
is available from your dealer.
If you are charging a remote (non-vehicle) battery,
turn on the headlamps to boost the vehicle
system voltage and properly charge the battery.
Your vehicle is also equipped with wiring for an
electric trailer brake controller. These wires are
located inside the vehicle on the driver’s side under
the instrument panel. These wires should be
connected to an electric trailer brake controller by
your dealer or a qualied service center.

Engine Fan Noise
Your vehicle has a clutched engine cooling fan.
When the clutch is engaged, the fan spins faster to
provide more air to cool the engine. In most
everyday driving conditions the clutch is not
engaged. This improves fuel economy and reduces
fan noise. Under heavy vehicle loading, trailer
towing, and/or high outside temperatures, the fan
speed increases when the clutch engages so
you may hear an increase in fan noise. This is
normal and should not be mistaken as the
transmission slipping or making extra shifts. It is
merely the cooling system functioning properly.
The fan will slow down when additional cooling is
not required and the clutch disengages.
You may also hear this fan noise when you start
the engine. It will go away as the fan clutch
disengages.
Power Steering Fluid
SeeEngine
Compartment Overview
on page 366for
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.

(e)Make sure the safety belt reminder light and all
your belts, buckles, latch plates, retractors, and
anchorages 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 look for any opened or broken airbag
coverings, and have them repaired or replaced.
The airbag system does not need regular
maintenance.
(f)Lubricate all key lock cylinders, hood latch
assembly, secondary latch, pivots, spring anchor,
release pawl, rear compartment hinges, outer
liftgate handle pivot points, rear door detent link,
roller mechanism, liftgate handle pivot points, latch
bolt, fuel door hinge, cargo door hinge, locks,
and folding seat hardware. 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)Inspect hoses for cracks, chang, leaks, kinks,
and proper installation.(h)Change automatic transmission uid and lter
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.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police, or delivery
service.
(i)Drain, ush, and rell cooling system.
This service can be complex; you should have
your dealer perform this service. See Engine
Coolant on page 379 for what to use. Inspect
hoses. Clean radiator, condenser, pressure cap,
and ller neck. Pressure test the cooling
system and pressure cap.
(j)A uid loss in any vehicle system could indicate
a problem. Have the system inspected and
repaired and the uid level checked. Add uid if
needed.

If your vehicle is leased, the leasing company
may require you to have insurance that assures
repairs with Genuine GM Original Equipment
Manufacturer (OEM) parts or Genuine
Manufacturer replacement parts. Read your lease
carefully, as you may be charged at the end of
your lease for poor quality repairs.
If an Accident Occurs
Here is what to do if you are involved in an
accident.
Try to relax and then check to make sure 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 911 for help.
Do not leave the scene of an accident 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 accident. Do not discuss your personal
condition, mental frame of mind, or anything
unrelated to the accident. This will help guard
against post-accident legal action.
If you need roadside assistance, call
GM Roadside Assistance. SeeRoadside
Assistance Program on page 504for 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.
