be sure
to drain all free-flowing oil from the filter before disposal. Don’t ever

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.
I
I
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.

The following explains your cooling system and how to add cool\
ant when it is low.
If you have a problem with engine overheating, see "Engine
Overheating" in the Index.
The proper coolant for your vehicle will:
Give freezing protection down to -20°F (-29°C) or -40°F (-40°C) for
Canadian vehicles and vehicles with the cold climate option.
Give boiling protection up to 258°F (125°C).
Protect' against rust and corrosion.
Help keep the proper engine temperature.

have
to have new ones put in-be sure you get new genuine 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.

The power steering pump is also used as the Hydro-Boost pump. \
Refer to
“Power Steering Fluid” in this section when. checking the fluid level or adding
fluid.
Fluid Leak Check
After the vehicle has been parked for awhile, inspect the surf\
ace beneath the
vehicle for water, oil, fuel or other fluids. Water dripping f\

should be found and corrected at once.

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.

Lock Cylinders
To be sure your locks operate properly, they must be lubricated. \
The
Maintenance Schedule will tell you how often to lubricate them. See
“Recommended Fluids and Lubricants” in the Index for the \
proper lubricant to use.
You should not use penetrating oils because they could wash out th\
e factory
installed lubricant and cause the lock to bind. De-icers which \
contain alcohol
could also wash away the lubricant,
so be sure to lubricate the lock after
using a de-icer
of this type.
Exhaust System
To help prevent damage to your exhaust system, do not continue to drive
your vehicle
if you notice:
Engine misfiring
Loss of performance
Other unusual operating conditions
Have your engine and exhaust system serviced regularly.
Three- Way Catalytic Converter
Your vehicle’s three-way catalytic converter is designed to reduce the
pollutants in your vehicle’s exhaust. Use only unleaded fuel in your vehicle.
If
you use leaded fuel, you could damage your three-way catalytic \
converter,
and other emission control components.
Malfunction Indicator Lamp (SERVICE ENGINE SOON light)
The Malfunction Indicator Lamp (SERVICE ENGINE SOONlight) on y\
our instrument panel lets you know when your emission system needs \
service.
The light will come on briefly when you start your engine to let you know
that the system is working.
If it does not come on when you start your
engine, or
if it comes on and stays on while you’re driving, your system \
may
need service. Your vehicle should still be driveable, but you should have your
system serviced right away.

Wipe with a clean cloth.
Using Solvent-Type Cleaner on Fabric
First, see if you have to use solvent-type cleaner at all. Some spots and
stains will clean
off better with just water and mild soap.
If you need to use it, then:
Gently scrape excess soil from the trim material with a clean,\
dull knife
or scraper. Use very little cleaner, light pressure and clean cloths
(preferably cheesecloth). Cleaning should start
at the outside of the stain,
“feathering” toward the center. Keep changing to a clean \
section of the
cloth.
When you clean a stain from fabric, immediately dry the area \
with an air hose, hair dryer,
or heat lamp to help prevent a cleaning ring. (See
previous
NOTICE.)
Fabric Protection
Your vehicle has upholstery that has been treated with ScotchgardTM \
Fabric
Protector, a 3M product. ScotchgardTM protects fabrics by repell\
ing oil and
water, which are the carriers of most stains. Even with this protection, you
still need
to clean your upholstery often to keep it looking new.
Further information on cleaning is available by calling 1-800-43\
3-3296 (in
Minnesota, 1-800-642-61 67).
Special Cleaning Problems
Greasy or Oily Stains: Like grease, oil, butter, margarine, shoe polish, coffee
with cream, chewing gum, cosmetic creams, vegetable oils, wax crayon, tar
and asphalt.
Carefully scrape off excess stain.
Then follow the solvent-type instructions above.

Downloaded from www.Manualslib.com manuals search engine Shoe polish, wax crayon, tar and asphalt will stain if left on a vehicle
seat fabric. They should be removed as soon as possible. Be careful,
because the cleaner will dissolve them and may cause them
to bleed.
Non-Greasy Stains: Like catsup, coffee (black), egg, fruit, fruit juice, milk,
soft drinks, wine, vomit, urine and blood.
Carefully scrape off excess stain, then sponge the soiled area \
with cool
water.
If a stain remains, follow the foam-type instructions above.
If an odor lingers after cleaning vomit or urine, treat the area with a
watedbaking soda solution:
1 teaspoon (5 ml) of baking soda to 1 cup
(250 ml) of lukewarm water.
Finally, if needed, clean lightly with solvent-type cleaner.
