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 P (Park) yet.
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.
4. Reapply the regular brakes. Then apply your parking brake, and \
shift to
P (Park).
5. Release the regular brakes.
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 fluid (don’t ove\
rfill),
engine oil, axle lubricant, belt, cooling system, and brake adj\
ustment. 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.

Doing Your Own Service Work
If you want to do some of your own service work, you’ll want to get the
proper General Motors Service Manual. It tells you much more a\
bout how to
service your vehicle than this manual can.
To order the proper service
manual, see ‘Service Publications’’ in the Index.
You should keep a record with all parts receipts and list the mil\
eage and the
date .of any service work you perform. See “Maintenance Reco\
rd” in the
Index.
You can be injured
if you try to do service work on a vehicle without
knowing enough about
it.
Be sure you have sufficient knowledge, experience, and 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 “metric” fasteners can be easily confus\
ed.
If you
use the wrong fasteners, parts can later break or fall off. You
I could be hurt.

Air Cleaner
To Remove the Air CIeaner Filter:
If you have the 4.3L engine (VIN Code Z) with the round air cleaner, you
must first remove the engine cover before changing the filter. \
(See “Engine
Cover” earlier in this section.) After removing the engine cover, unscrew the
wing nut to take the cover off the air cleaner. After changing the filter,\
put
the cover back on and be sure the wing nut is properly tight\
ened. Be sure air cleaner lid is correctly positioned to seal out dust and contaminants that
are harmful to your engine.
If you have the
4.3L engine (VIN Code W) with the square air cleaner, you
can change the air cleaner filter without removing the engine cover. Just lift
the hood, unsnap both clips and remove the top. After changing the filter,
snap both clips to secure the air cleaner. Be sure air cleaner lid
is correctly
positioned to seal out dust and contaminants that are harmful to your engine.
Refer to the Maintenance Schedule to determine when to replace the air
cleaner filter. See “Scheduled Maintenance Services” in the Index.

Automatic Transmission Nuid
When to Check and Change:
A good time to check your automatic transmission fluid level is when the
engine oil is changed. Refer to the Maintenance Schedule
to determine when
to change your fluid. See “Scheduled Maintenance Services” in the Index.
How to Check:
Because this operation can be a little difficult, you may choo\
se to have this
done at a
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.
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 part-
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:
When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
In heavy traffic-especially in hot weather.
While pulling a trailer.

If the fluid level is low, add only enough to bring the level up to the COLD

fluid, generally less than a pint. Don’t overfill. We recommend you use only
fluid labeled DEXRON@IIE, because fluids with that label are ma\
