When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
start your engine,
shift into a gear, and
release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store
the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transmission uid (don’t overll),
engine oil, axle lubricant, belt, cooling system and
brake system. Each of these is covered in this manual,
and the Index will help you nd them quickly. If
you’re trailering, it’s a good idea to review these sections
before you start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.
Trailer Wiring Harness
The optional heavy-duty trailer wiring package includes
a seven-wire harness assembly at the rear of the
vehicle and a four-wire harness assembly under the left
hand side of the instrument panel. The seven-wire
harness assembly is taped together and located in a
frame pocket at the driver side rear left corner of
the frame. The seven-wire harness includes a 30-amp
feed wire. Both harnesses come without connectors and
should be wired by a qualied electrical technician.
The technician can use the following color code chart
when connecting the wiring harness to your trailer
and trailer brake controller.

Adding Coolant
If you need more coolant, add the proper DEX-COOL®
coolant mixtureat the coolant recovery tank,but be
careful not to spill it.
{CAUTION:
Turning the radiator pressure cap when the
engine and radiator are hot can allow steam
and scalding liquids to blow out and burn you
badly. With the coolant recovery tank, you will
almost never have to add coolant at the
radiator. Never turn the radiator pressure
cap — even a little — when the engine and
radiator are hot.
{CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Do not spill coolant on a hot engine.Occasionally check the coolant level in the radiator. For
information on how to add coolant to the radiator,
seeCooling System on page 5-26.
Radiator Pressure Cap
The radiator pressure cap is located near the center of
the engine compartment. SeeEngine Compartment
Overview on page 5-12for more information on location.
Notice:If the pressure cap is not tightly installed,
coolant loss and possible engine damage may
occur. Be sure the cap is properly and tightly
secured.
Engine Overheating
You will nd an engine coolant temperature gage on
your vehicle’s instrument panel. SeeEngine Coolant
Temperature Gage on page 3-31for more information.

Vinyl
Use warm water and a clean cloth.
Rub with a clean, damp cloth to remove dirt. This
may have to be done more than once.
Things like tar, asphalt, and shoe polish will stain if
they are not removed quickly. Use a clean cloth
and vinyl cleaner. See your dealer for this product.
Instrument Panel
Use only mild soap and water to clean the top surfaces
of the instrument panel. Sprays containing silicones
or waxes may cause annoying reections in the
windshield and even make it difficult to see through the
windshield under certain conditions.
Interior Plastic Components
Use only a mild soap and water solution on a soft cloth
or sponge. Commercial cleaners may affect the
surface nish.
Glass Surfaces
Glass should be cleaned often. GM Glass Cleaner or a
liquid household glass cleaner will remove normal
tobacco smoke and dust lms on interior glass. See
Vehicle Care/Appearance Materials on page 5-90.
Notice:If you use abrasive cleaners when cleaning
glass surfaces on your vehicle, you could scratch
the glass and/or cause damage to the rear window
defogger and the integrated radio antenna. When
cleaning the glass on your vehicle, use only a soft
cloth and glass cleaner.
Care of Safety Belts
Keep belts clean and dry.
{CAUTION:
Do not bleach or dye safety belts. If you do, it
may severely weaken them. In a crash, they
might not be able to provide adequate
protection. Clean safety belts only with mild
soap and lukewarm water.

This is the legal identier for your vehicle. It appears on
a plate in the front corner of the instrument panel, on
the driver’s side. You can see it if you look through the
windshield from outside your vehicle. The VIN also
appears on the Vehicle Certication and Service Parts
labels and the certicates of title and registration.
Engine Identication
The eighth character in your VIN is the engine code.
This code will help you identify your engine,
specications and replacement parts.
Service Parts Identication Label
You will nd this label on the front passenger door
frame. It is very helpful if you ever need to order parts.
On this label you will nd the following:
VIN
Model designation

Customer Assistance and
Information
Customer Satisfaction Procedure
Your satisfaction and goodwill are important to
your dealer and to Chevrolet. Normally, any concerns
with the sales transaction or the operation of your
vehicle will be resolved by your dealer’s sales or service
departments. Sometimes, however, despite the best
intentions of all concerned, misunderstandings can
occur. If your concern has not been resolved to your
satisfaction, the following steps should be taken:
STEP ONE:Discuss your concern with a member of
dealership management. Normally, concerns can
be quickly resolved at that level. If the matter has
already been reviewed with the sales, service or parts
manager, contact the owner of the dealership or
the general manager.
STEP TWO:If after contacting a member of dealership
management, it appears your concern cannot be
resolved by the dealership without further help, contact
the Chevrolet Customer Assistance Center by calling
1-800-222-1020. In Canada, contact GM of Canada
Customer Communication Centre by calling
1-800-263-3777 (English) or 1-800-263-7854 (French).We encourage you to call the toll-free number in order
to give your inquiry prompt attention. Please have
the following information available to give the Customer
Assistance Representative:
Vehicle Identication Number (VIN). This is
available from the vehicle registration or title, or the
plate at the top left of the instrument panel and
visible through the windshield.
Dealership name and location.
Vehicle delivery date and present mileage
(kilometers).
When contacting Chevrolet, please remember that your
concern will likely be resolved at a dealer’s facility.
That is why we suggest you follow Step One rst if you
have a concern.
STEP THREE:Both General Motors and your dealer
are committed to making sure you are completely
satised with your new vehicle. However, if you continue
to remain unsatised after following the procedure
outlined in Steps One and Two, you should le with the
BBB Auto Line Program to enforce any additional
rights you may have. Canadian owners refer to your
Warranty and Owner Assistance Information booklet for
information on the Canadian Motor Vehicle Arbitration
Plan (CAMVAP).
