Downloaded from www.Manualslib.com manuals search engine Let only qualified technicians work on your air bag
system. Improper service
can mean that your air bag
system won’t work properly. See your dealer
for service.
NOTICE:
~ ~ ~~~
If you damage the covering for the driver’s or the
right front passenger’s air bag, the bag may not
work properly. You may have to replace the air
bag module in the steering wheel or both the
air
bag module and the instrument panel for the
right front passenger’s
air bag. Do not open or
break the air bag coverings.
Servicing Your Air Bag-Equipped Vehicle
Air bags affect how your vehicle should be serviced.
There are parts
of the air bag system in several places
around your vehicle. You don’t
want the system to
inflate while someone is working on your vehicle. Your
GM dealer and the service manual have information
about servicing your vehicle and the air bag system. To
purchase a service manual, see “Service and Owner
Publications”
in the Index.
I a CAUTION:
For up to 10 minutes after the ignition key is
turned
off and the battery is disconnected, an air
bag can still inflate during improper service.
You
can be injured if you are close to an air bag when
it inflates. Avoid wires wrapped with yellow tape
or yellow connectors. They are probably part
of
the air bag system. Be sure to follow proper
service procedures, and make sure the person
performing work for you is qualified to do
so.
The air bag system does not need regular maintenance.

Downloaded from www.Manualslib.com manuals search engine Safety Belt Extender
If the vehicle’s safety belt will fasten around you, you
should use it.
But if a safety belt isn’t long enough to fasten, your
dealer will order you an extender. It’s free. When
you go
in to order it, take the heaviest coat you will wear, so the
extender will be long enough for
you. The extender will
be just for
you, and just for the seat in your vehicle that
you choose. Don’t let someone else use it, and use it
only for
the seat it is made to fit. To wear it, just attach it
to the regular safety belt.
Checking Your Restraint Systems
Now and then, make sure the safety belt reminder light
and all your belts, buckles, latch plates, retractors and
anchorages are working properly. If your vehicle has a
built-in child restraint, also periodically make sure the
harness straps, latch plates, buckle, clip, retractors and
anchorages are working properly.
Look for any other
loose or damaged safety belt and built-in child restraint
system parts. If
you see anything that might keep a
safety belt or built-in child restraint system from doing
its job, have it repaired. Torn
or frayed safety belts may not protect
you in a
crash. They can rip apart under impact forces. If a belt
is
torn or frayed, get a new one right away.
If your vehicle has the built-in child restraint, torn or
frayed harness straps can rip apart under impact forces
just like torn or frayed safety belts can. They may
not
protect a child in a crash. If a harness strap is torn or
frayed, get a new harness right away.
Also look for any opened or broken air bag covers, and
have them repaired or replaced. (The air bag system
does not need regular maintenance.)

You really should not park your vehicle, with a trailer
attached, on a hill.
If something goes wrong, your rig
could start to move. People can be injured, and both
your vehicle and the trailer can be damaged.
But if you ever have
to park your rig on a hill, here’s
how
to do it:
1. Apply your regular brakes, but don’t shift into
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
PARK (P) yet.
4. Reapply the regular brakes. Then apply your parking
5. Release the regular brakes.
brake,
and shift to
PARK (P).
When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
0 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 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.

Your GM dealer knows your vehicle best and wants you
to be happy with
it. We hope you’ll go to your dealer for

Doing Your Own Service Work
If you want to do some of your own service work, you’ll
want to get the proper GM Service Manual. It tells you
much more about how to service your vehicle than this
manual can.
To order the proper service manual, see
“Service and Owner Publications” in
the Index. Your
vehicle has an air bag system. Before attempting to
do your own service work, see “Servicing Your Air
Bag-Equipped Vehicle” in the Index.
You should keep
a record with all parts receipts and list
the mileage and the date
of any service work you
perform. See “Maintenance Record” in the Index.
You can be injured and
your vehicle could be
damaged if you try to
do service work on a
vehicle without knowing enough about it.
Be sure you have sufficient knowledge,
experience, the proper replacement parts
and tools before you attempt any vehicle
maintenance task.
Be sure to use the proper nuts, bolts and
other fasteners. “English” and “metrid’
fasteners can be easily confused. If you use
the wrong fasteners, parts can later break
or fall off. You could be hurt.

Downloaded from www.Manualslib.com manuals search engine Engine Oil Additives
Don’t add anything to your oil. Your GM dealer is ready
to advise if you think something should be added.
When to Change Engine Oil
If any one of these is true for you, use the short tripkity
maintenance schedule:
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
Most trips are through dusty areas.
You frequently tow a trailer or use a carrier on top of
your vehicle.
The vehicle is used for delivery service, police, taxi
or other commercial application.
Driving under these conditions causes engine oil
to
break down sooner. If any one of these is true for your
vehicle, then you need to change your oil and filter
every
3,000 miles (5 000 km) or 3 months -- whichever
occurs first. If
none
of them is true, use the long triphighway
maintenance schedule. Change the oil and filter every
7,500 miles (12 500 km) or 12 months -- whichever
occurs first. Driving a vehicle with a
fully warmed
engine under highway conditions causes engine
oil to
break down slower.
What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don’t let used oil stay
on your skin
for very long. Clean your skin and nails with soap and
water,
or a good hand cleaner. Wash or properly throw
away clothing or rags containing used engine oil. (See
the manufacturer’s warnings about the use and disposal
of oil products.)
Used oil can be a real threat
to the environment. If you
change your own oil, be sure to drain all free-flowing oil
from the filter before disposal. Don’t ever dispose of oil
by putting
it in the trash, pouring it on the ground, into
sewers,
or into streams or bodies of water. Instead,
recycle
it by taking it to a place that collects used oil. If
you have a problem properly disposing of your used oil,
ask your dealer, a service station or a local recycling
center for help.

To remove the air filter, lift the hood, unsnap both clips
and remove the top. After changing the filter, snap both
clips to secure the air cleaner. Be sure
the air cleaner lid
is correctly positioned
to seal out dust and contaminants
that are harmful to your engine.
Make sure
the fresh air hose is still attached after the
filter change.
Refer to
the Maintenance Schedule to determine when to
replace the air filter and the crankcase ventilation filter.
See “Scheduled Maintenance” in the Index.
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:
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
15,000 miles
(25 000 km) if the vehicle is mainly driven under one or
more
of these conditions:
0 In heavy city traffic where the outside temperature
In hilly or mountainous terrain.
0 When doing frequent trailer towing.
regularly reaches
90 OF (32 ” C) or
higher.
Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, change the fluid and filter every
30,000 miles
(50 000 km).
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 dealership
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.
Wait at least 30 minutes before checking the
transmission fluid level if you have been driving:
0 When outside temperatures are above 90°F (32°C).
0 At high speed for quite a while.
0 In heavy traffic -- especially in hot weather.
0 While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which
is 180°F to 200°F
(82°C to 93°C).

Downloaded from www.Manualslib.com manuals search engine How to Add Fluid
Refer to the Mainterl‘ance 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
one pint (0.5 L).
Don P overjill.
I NOTICE:
-
After adding fluid, recheck the fluid level as
described under “How to Check.”
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.
All-Wheel Drive
If you have an all-wheel-drive vehicle, be sure to
perform
the lubricant checks described in this section.
However,
they have two additional systems that
need lubrication.
Transfer Case
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. When to Check Lubricant
Refer to the Maintenance Schedule to determine
how
often to check the lubricant. See “Periodic Maintenance
Inspections’’
in the Index.
