Downloaded from www.Manualslib.com manuals search engine Parking on Hills
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
5. Release the regular brakes.
“P” (Park).
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. Thin.gs 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 Light Wiring

Downloaded from www.Manualslib.com manuals search 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
filter.
See “Scheduled Maintenance Services”
in the Index.
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 drivin\

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. 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 choose 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.
6-20

Downloaded from www.Manualslib.com manuals search engine 4. If the fluid level
is in the
acceptable range,
push the dipstick
back in all the
way.
How to Add Fluid
Refer to the Maintenance Schedule to determine what kind of transmission
fluid to use. See “Recommended Fluids and Lubricants”
in the Index.
If the fluid level
is low, add only enough of the proper fluid to bring the
level up to the
COLD area for a cold check or the HOT area for a hot
check. It doesn’t take much fluid, generally less than
a pint. Don’t overfill.
We recommend you use only fluid labeled DEXRON@-I11 or
DEXRON@-IIE, because fluids with that label are made especially for our
automatic transmission. Damage caused by fluid other than DEXRON
-111
or DEXRON@-IIE is not covered by your new vehicle warranty.
d
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.

filter every
15,000 miles (25 000 km) 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
In hilly or mountainous terrain.
higher.
Frequent trailer pulling.
0 Uses
such as taxi, police, delivery or other commercial service.
If the vehicle
is not used mainly under any of these conditions, change

7. FUEL FILTER REPLACEMENT*$ - Replace the fuel filter at the
specified interval or sooner if clogged.
8. SPARK PLUG REPLACEMENT* - Replace spark plugs with the
type listed in Section
6. See “Specification Charts” in the Index.
9. SPARK PLUG WIRE INSPECTION* - Clean wires and inspect
for bums, cracks or other damage. Check the wire boot fit at the
distributor and at the spark plugs. Replace wires as needed.
Adjust timing to underhood label specifications. Inspect the inside and
outside
of the distributor cap and rotor for cracks, carbon tracking and
corrosion. Clean or replace as needed.
10. ENGINE TIMING CHECK AND DISTRIBUTOR CHECK*$ -
11. FUEL TANK, CAP AND LINES INSPECTION*$ - Inspect the

Look for cracks, fraying, wear, and proper tension. Adjust or
replace as needed.
* An Emission Control Service
$ The California Air Resources Board has determined that the failure to perform \
this
maintenance item will not nullify the emission warranty or limit recall liability prior to the
completion of vehicle useful life. General Motors, however, urges that all re\
commended
maintenance services be performed at the indicated intervals and\
the maintenance be
recorded.
