Parking
on a Hill
1. Apply your regular brakes and hold the pedal down
whiie you:
Start your engine:
Shift into a gear: and
Release the parking brake.
3,. 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.

Downloaded from www.Manualslib.com manuals search engine Trailer Wiring Harness
The light duty trailer wiring is a six-wire harness
assembly. The optional heavy-duty trailer wiring is an
eight-wire harness assembly. The harnesses are stored
under the vehicle, along the passenger-side frame
crossmember on two-door vehicles or on the driver’s
side corner frame crossmember on four-door vehicles.
The heavy-duty trailer wiring has
a 30-amp feed wire
with an inline
fuse located by the junction block. See
“Fuses and Circuit Breakers”
in the Index. Both
harnesses have no connector and should be wired by a
qualified electrical technician. The technician can
use
the following color code chart when connecting the
wiring harness
to your trailer.
Dark Blue: Use for electric trailer brakes or
auxiliary wiring.
0 Red: Use for battery charging; it connects to the
starter solenoid (eight-wire harness only).
0 Light Green: Back-up lamps (eight-wire
harness only).
Brown: Taillamps and parking lamps.
0 Yellow: Left stoplamp and turn signal.
0 Dark Green: Right stoplamp and turn signal.
0 White (Heavy Gage): Ground wire.
0 White (Light Gage): Auxiliary stoplamp.
Securely 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.

When using concentrated washer fluid,
follow the manufacturer's instructions for
adding water. Don't mix water with ready-to-use washer
fluid, Water can cause the solution to freeze
and damage your washer fluid tank and
other parts
of the washer system. Also,
water doesn't clean as well as washer fluid.
Fill your washer fluid tank only
three-quarters full when it's very cold. This
allows for expansion if freezing occurs,
which could damage the tank
if it is
completely
full.
Don't use radiator antifreeze in your
windshield washer. It can damage your
washer system and paint.
Brakes
Brake Fluid
c
Your brake master cylinder reservoir is here. It is filled
with DOT-3 brake fluid.

Downloaded from www.Manualslib.com manuals search engine There are only two reasons why the brake fluid level in
the reservoir might go down. The first is that the brake
fluid goes down
to an acceptable level during normal
brake lining wear. When new linings are put
in, the fluid
level goes back up. The other reason is
that fluid is
leaking out of the brake system. If it is, you should have
your brake system fixed, since a leak means that sooner
or later your brakes won’t work well, or won’t work
at all.
So, it isn’t a good idea to “top off’ your brake fluid.
Adding brake fluid
won’t correct a leak. If you add fluid
when your linings are worn,
then you’ll have too much
fluid when
you get new brake linings. You should add
(or remove) brake fluid,
as necessary, only when work is
done on the brake hydraulic system.
I A CAUTION:
If you have too much brake fluid, it can spill on the
engine. The fluid
will burn if the engine is hot
enough. You or others could be burned, and your
vehicle could be damaged. Add brake fluid only
when work is done on the brake hydraulic system.
Refer to the Maintenance Schedule to determine when to
check your brake fluid. See “Periodic Maintenance
Inspections” in the Index.
Checking Brake Fluid
I
&-
You can check the brake fluid without taking off the cap.
Just look at the windows
on the brake fluid reservoir.
The fluid levels should be above MIN. If they aren’t,
have your brake system checked
to see if there is a leak.
After work is done
on the brake hydraulic system, make
sure the levels are above
MIN and below the top of
each window.

Downloaded from www.Manualslib.com manuals search engine What to Add When
you do need brake fluid, use only DOT-3 brake
fluid -- such as Delco Supreme 11 @ (GM Part
No. 12377967). Use new brake fluid from a sealed
container
only.
Always clean the brake fluid reservoir cap and the area
around the cap before removing it. This
will help keep
dirt from entering the reservoir.
1 A CAUTION: 1
With the wrong kind of fluid in your brake
system, your brakes may not work well,
or they
may
not even work at all. This could cause a
crash. Always use the proper brake fluid.
NOTICE:
Using the wrong fluid can badly damage
brake system parts. For example,
just a few
drops
of mineral-based oil, such as engine
oil, in your brake system can damage brake
system parts
so badly that they’ll have to be
replaced. Don’t let someone put in the
wrong kind
of fluid.
If you spill brake fluid on your vehicle’s
painted surfaces, the paint finish can be
damaged. Be careful not
to spill brake fluid
on your vehicle. If you do, wash it off
immediately. See “Appearance Care” in
the Index.

Downloaded from www.Manualslib.com manuals search engine Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or
if there is a rapid increase in pedal
travel. This could be
a sign of brake trouble.
Brake Adjustment
Every time you make a brake stop, your disc brakes
adjust for wear.
If your brake pedal goes down farther than normal. your
rear drum brakes may need adjustment. Adjust them by
backing up and firmly applying the brakes a few times.
Replacing Brake System Parts
The braking system on a modern vehicle is complex. Its
many parts have
to be of top quality and work well
together if the vehicle is to have really good braking.
Your vehicle was designed and tested with top-quality
GM brake parts. When
you replace parts
of your braking system -- for
example,
when your brake linings wear down and you
have to have new ones put in -- be sure you get new
approved
GM replacement parts. If you don‘t, your
brakes may
no longer work properly. For example, if
someone puts in brake linings that are wrong for your
vehicle, the balance between your front and rear brakes
can change
-- for the worse. The braking performance
you’ve come
to expect can change in many other ways if
someone puts in the wrong replacement brake parts.
Battery
Every new vehicle has a Delco Freedom@ battery. You
never have to add water to one
of these. When it’s time
for a new battery, we recommend a Delco Freedom
battery. Get one that has the replacement number shown
on the original battery’s label.

? The U.S. Environmental Protection Agency or 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 the vehicle’s
useful life. We, however,
urge that all recommended maintenance services
be
performed at the indicated intervals and the maintenance
be recorded.
# Lubricate the front suspension, ball joints, steering
linkage and transfer case shift linkage, parking brake
cable guides, propshaft splines, universal joints and
brake pedal springs.
+ A good time to check your brakes is during tire
rotation. See “Brake System Inspection” under “Periodic Maintenance Inspection” in Part
C of this schedule.

Lubricants’’ in

Locking Differential -- Drain fluid and refill at first
engine oil change. At subsequent oil changes, check
fluid level and add fluid as needed. If driving in
dusty areas or towing a trailer, drain fluid and refill
every
15,000 miles (25 000 km).
Standard Differential -- Check fluid level and add
fluid
as needed at every oil change. If driving in
dusty areas
or towing a trailer, drain fluid and refill
every
15,000 miles (25 000 km).
More frequent lubrication may be required for
heavy-duty
or off-road use.
