Downloaded from www.Manualslib.com manuals search engine 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.
If you have too much brake fluid, it can spill on the engine. The fluid I
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.
I
Refer to the Maintenance Schedule to determine when to check your brake
fluid. See “Periodic Maintenance Inspections” in the Index.
To Check Brake Fluid:
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.
What To Add:
When you do need brake fluid, use only DOT-3 brake fluid-such \
as Delco
Supreme
ll@ (GM Part No. 1052535), Use new brake fluid from a sealed
container only.

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. Vehicles we design and test have top-quality
GM brake parts in
them, as your vehicle does when
it is new. When you replace parts of your

Hood Latches and Hood Hinge
The Maintenance Schedule will tell you how often to lubricate the hood latch
and hood hinge assembly. See “Recommended Fluids and Lubricants”\
in the
Index for the proper lubricant
to use.
Propeller Shaft Slip Splines/Universal Joints
The Maintenance Schedule will tell you how often the slip splines must be
lubricated. See “Recommended Fluids and Lubricants” in the \
Index for the
proper lubricant
to use.
Constant Velocity Joints (All- Wheel Drive Only)
The Maintenance Schedule will tell you how often to lubricate the the
constant velocity joints. See “Recommended Fluids and Lubrican\
ts” in the
Index for the proper lubricant
to use.
Sliding Door Tracks
Your vehicle’s sliding door has three tracks which need lubricatio\
n.
For the upper and lower tracks, open the door, wipe the track\
clean and then
lubricate with Lubriplate@ White Grease.
For the outside middle track, close the door after you finish \
the upper and
lower tracks. Then, wipe the track clean and lubricate with Lu\
briplateB White
Grease.
Body
Normal use of your vehicle will cause metal-to-metal wear at some points \
on
the cab and body
if they are not lubricated.
tor exposed surfaces, such as door checks, door lock bolts, lock s\
triker
plates, dovetail bumper wedges, etc., a thin film
of engine oil should be
applied.
Where oil holes are provided in the body or cab, a dripless \
oil can be used.
The seat adjusters and seat track should be lubricated with chassis grease.
Door weatherstrips and rubber hood bumpers should be lightly coated with
a
rubber lubricant.
Never use
too much of any lubricant and be sure to wipe up any extra
lubricant when you are finished.
Some parts that need lubricating are hard
to get at. Window regulators and
controls are inside the doors. You can get to these by removing the trim
panels.

Glass
Glass should be cleaned often. GM Glass Cleaner (GM Part No. 1050427) or
a liquid household glass cleaner will remove normal tobacco smo\
ke and dust
films.
Don’t use abrasive cleaners on glass, because they may cause\
scratches.
Avoid placing decals on the inside rear window, since they may\
have to be
scraped
off later.
If abrasive cleaners are used on the inside of the rear window, \
an electric
defogger element may be damaged. Any temporary license should n\
ot be
attached across the defogger grid.
Cleaning the Outside of fhe Windshield, Backglass and Wiper
Blades
If the windshield is not clear after using the windshield washer, or if the wiper
blade chatters when running, wax or other material may be on the blade or
windshield.
Clean the outside of the windshield with GM Windshield Cleaner, Bon-Ami
Powder@
(GM Part No. 1050011). The windshield is clean if beads do not
form when you rinse it with water.
Clean the blade by wiping vigorously with a cloth soaked in full strength
windshield washer solvent. Then rinse the blade with water.
Wiper blades should be checked on a regular basis and replaced\
when worn.
Cleaning the Outside of Your Vehicle
The paint finish on your vehicle provides beauty, depth of color, gloss
retention and durability.
Washing Your Vehicle
The best way to preserve your vehicle’s finish is to keep it clean by washing
it often with lukewarm
or cold water.
Don’t wash your vehicle in the direct rays of the sun. Don’t use strong soaps
or chemical detergents. Use liquid hand, dish or car washing (non\
-detergent)
soaps. Don’t use cleaning agents that contain acid
or abrasives. All cleaning
agents should be flushed promptly and not allowed to dry on t\
he surface,
or
they could stain. Dry the finish with a soft, clean chamois or a 100% cotton
towel
to avoid surface scratches and water spotting.
High pressure vehicle washes may cause water
to enter your vehicle.
Finish Care
Occasional waxing or mild polishing of your vehicle may be necessary to
remove residue from the paint finish. You can get
GM approved cleaning
products from your dealer. (See “Appearance Care and Materia\
ls” in the Index.)

Downloaded from www.Manualslib.com manuals search engine Headlights
The headlight wiring is protected by a circuit breaker in the light switch. An
electrical overload will cause the lights
to go on and off, or in some cases to
remain
off. If this happens, have your headlight wiring checked right away.
Windshield Wipers
The windshield wiper motor is protected by a circuit breaker and a fuse. If
the motor overheats due to heavy snow, etc., the wiper will s\
top until the
motor cools. If the overload is caused by some electrical prob\
lem and not
snow, etc., be sure to get it fixed.
Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power windows a\
nd other power
accessories. When the current load is too heavy, the circuit b\
reaker opens
and closes, protecting the circuit until the problem is fixed
or goes away.
Trailer Wiring Harness
The optional seven-wire trailer wiring harness is protected by \
an in-line fuse
in the battery feed wire. This fuse is near the junction bloc\
k. See “Trailer
Wiring Harness” in the Index.
Fuse Block
K3629
The fuse block is under the instrument panel on the driver’\
s side. You can
remove the cover with
a screwdriver and then remove fuses with a fuse
extractor. To remove fuses
if you don’t have one, hold the end of the fuse
between your thumb and index finger and pull straight out.
