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.
Main ~ mr ~ ce 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 fluid (don’t
overfill), engine oil, axle lubricant, belt, cooling system
and brake adjustment. Each
of these is covered in this
manual, and the Index will help you find 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 eight-wire harness, if you have one, is stored under
your vehicle along the rear frame crossmember. It is
wrapped and bound with a plastic strap. The harness has
a 30-amp battery feed and no connector, and
you should
have a qualified electrical service person wire your
harness for
you. Attach the harness to the trailer, then
tape or strap
it to your vehicle’s frame rail. Be sure you
leave it loose enough so the wiring doesn’t bend or
break, but not
so loose that it drags on the ground.
Store the harness in its original place. Wrap the harness
together and tie it neatly
so it won’t be damaged.
The five-wire harness, if you have one, is stored inside
the vehicle at
the passenger side rear corner, behind the
jack. This should be wired by a qualified electrical
service person.
It must be routed out of your vehicle
between the rear door and the floor, with enough of the
harness left on both sides
so that the trailer or the body
won’t pull
it.
Store the harness in its original place. Wrap the harness
together and tie it neatly
so it won’t be damaged.

- CAUTAN:
Operating the engine with the air cleaner off can
cause you or others to be burned. The air cleaner
not only cleans the
air, it stops flame if the engine
backfires.
If it isn’t there, and the engine
backfires, you could be burned. Don’t drive with
it
off, and be careful working on the engine with
the air cleaner off.
I NOTICE: I
If the air cleaner is off, a backfire can cause a
damaging engine fire. And, dirt can easily get
into your engine, which will damage it. Always
have the air cleaner in place when you’re driving.

Downloaded from www.Manualslib.com manuals search engine Automatic Transmission Fluid
When to Check and Change
A good time to check your automatic transmission fluid
level is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83
000 km) if the vehicle’s GVWR is over 8,600 or
if
the vehicle is mainly driven under one or more of
these conditions:
0 In heavy city traffic where the outside temperature
0 In hilly or mountainous terrain.
regularly reaches
90°F (32°C) or
higher.
0 When doing frequent trailer towing.
0 Uses such as found in taxi, police or delivery service.
If your vehicle’s
GVWR is not over 8,600 and you do
not use your vehicle under any
of these conditions, the
fluid and filter do
not require changing.
See “Scheduled Maintenance Services” in the Index.
How to Check
.Because this operation can be a little difficult, you
may choose to have this done at your GM dealer
Service Department.
If you do it yourself, be sure
to follow all the
instructions here, or you could get a false reading
on
the dipstick.
NOTICE:
Too much or too little fluid can damage your
transmission. Too much can mean that some of
the
fluid could come out and fall on hot engine
parts or exhaust system parts, starting a fire. Be
sure to get an accurate reading if you check your
transmission
fluid.

Downloaded from www.Manualslib.com manuals search engine How to Add Fluid Rear Axle
Refer to the Maintenance Schedule to determine what
kind
of transmission fluid to use. See “Recommended
Fluids and Lubricants” in the Index.
Add fluid only after checking the transmission fluid
HOT. (A COLD check is used only as a reference.) If
the fluid level is low, add only enough
of the proper
fluid to bring the
level up to the HOT area for a hot
check.
It doesn’t take much fluid, generally less than a
pint (0.5 L). Don ’t overjX. We recommend you use only
fluid labeled DEXRON@-111, because fluid with that
label is made especially for your automatic transmission.
Damage caused by fluid other than DEXRON-I11 is not
covered by your new vehicle warranty.
After adding fluid, recheck the fluid level as
described under
“How to Check.”
When to Check and Change Lubricant
Refer to the Maintenance Schedule to determine how
often to check
the lubricant and when to change it. See
“Scheduled Maintenance Services” in
the Index.
How to Check Lubricant
If the level is below the
bottom
of the filler plug
hole, you’ll need to add
some lubricant. Add
enough lubricant
to raise
the level to the bottom of
the filler plug hole.
0 When the correct fluid level is obtained, push the
dipstick back
in all the way; then flip the handle
down to lock the dipstick in place.
What to Use
Refer to the Maintenance Schedule to determine what
kind
of lubricant to use. See “Recommended Fluids and
Lubricants” in the Index.

Downloaded from www.Manualslib.com manuals search engine Tire Inspection and Rotation
Tires should be inspected every 6,000 to 8,000 miles
(10 000 to 13 000 km) for any signs of unusual wear. If
unusual wear is present, rotate your tires as soon as
possible and check wheel alignment. Also check for
damaged tires or wheels. See “When It’s Time for New
Tires” and “Wheel Replacement” later in this section for
more information. If your vehicle has dual rear wheels,
also see “Dual Tire Operation’’ later in this section.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle: The first
rotation is the most important. See “Scheduled
Maintenance Services” in the Index for scheduled
rotation intervals.
I FRT FRT
If your vehicle has single rear wheels, always use one of
the correct rotation patterns shown here when rotating
your tires.
II
If your vehicle has dual rear wheels, always use one of
the correct rotation patterns shown here when rotating
your tires.
When you install dual wheels, be sure the vent holes in
the inner and outer wheels on each side are lined
up.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the
Certificationmire label. Make certain that all wheel nuts
are properly tightened. See “Wheel Nut Torque’’ in
the Index.

Introduction
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle
in good working condition, but also helps the
environment. All recommended maintenance procedures
are important. Improper vehicle maintenance can even
affect the quality
of the air we breathe. Improper fluid
levels or the wrong tire inflation can increase
the level
of emissions from your vehicle. To help protect our
environment, and
to keep your vehicle in good
condition, please maintain
your vehicle properly.

Downloaded from www.Manualslib.com manuals search engine How This Section is Organized
The remainder of this section is divided into five parts:
“Part A: Scheduled Maintenance Services” shows
what to have done and how often. Some of these
services can be complex,
so unless you are technically
qualified and have
the necessary equipment, you should
let your dealer’s service department or another qualified
service center
do these jobs.
kerformmg maintenance work on a vehicle can
be dangerous.
In trying to do some jobs, YOU can
be seriously injured.
Do your own maintenance
work only if you have the required know-how
and the proper tools and equipment for the job.
If you have any doubt, have
a qualified
technician do the work.
If you are skilled enough to do some work on your
vehicle, you will probably want to get the service
information
GM publishes. See “Service and Owner
Publications’’ in the Index.
“Part B: Owner Checks and Services” tells you what
should be checked whenever
you stop for fuel. It also
explains what
you can easily do to help keep your
vehicle
in good condition.
“Part C: Periodic Maintenance Inspections” explains
important inspections that your
GM dealer’s service
department or another qualified service center
should perform.
“Part D: Recommended Fluids and Lubricants” lists
some products
GM recommends to help keep your
vehicle properly maintained. These products, or their
equivalents, should be used whether you do the work
yourself or have it done.
“Part E: Maintenance Record” provides a place for
you
to record the maintenance performed on your
vehicle. Whenever any maintenance is performed, be
sure to write it down
in this part. This will help you
determine when your next maintenance should be done.
In addition, it is a good idea to keep your maintenance
receipts. They may be needed
to qualify your vehicle for
warranty repairs.

Services
Using Your Maintenance Schedule
The proper fluids and lubricants to use are 1iste.d in
Part D. Make sure whoever services your vehicle uses
these.
All parts should be replaced and all necessary
repairs done before you or anyone else drives the
vehicle.
We at General Motors want to help you keep your
vehicle
in good working condition. But we don’t know
exactly how you’ll drive it. You may drive very short
distances only a
few times a week. Or you may drive
long distances
all the time in very hot, dusty weather.
You may use your vehicle in making deliveries. Or
you may drive
it to work, to do errands or in many
other ways.
Because of all the different ways people. use their GM
vehicles, maintenance needs vary.
You may even need
more frequent checks and replacements than you‘ll find
in the schedules in this section. So please read this
section and note how
you drive. If you have any
questions on how to keep your vehicle
in good
condition, see
your GM dealer.
This part tells you
the maintenance services you should
have done and when
you should schedule them. If you
go to your dealer for your service needs, you’ll know
that GM-trained and supported service people will
perform the work using genuine GM parts.
I nese schedules are for vehicles that:
0 carry passengers and cargo within recommended
limits. You
will find these limits on your vehicle’s
CertificatiodTire label. See “Loading Your Vehicle”
in the Index.
0 are driven on reasonable road surfaces within legal
driving limits.
0 use the recommended fuel. See “Fuel“ in the Index.
Selecting the Right Schedule
First you’ll need to decide which of the two schedules is
right for your vehicle. Here’s how to decide which
schedule
to follow:
Gasoline engine vehicles and diesel engine vehicles
have different maintenance requirements.
If you have a
diesel engine, follow
a schedule designated for diesel
engine vehicles only.
See the Diesel Engine Supplement for diesel engine
maintenance schedules.
