vehicle. However, you can use
SAE IOW-30 if it’s going
to be
0°F (-18°C) or above. These numbers on an oil

See if any one of these is true for you:
0 Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
Most trips are through dusty areas.
0 You frequently tow a trailer or use a carrier on top of
your vehicle.
The vehicle is used for delivery service, police, taxi
Driving under these conditions causes engine oil to
break down sooner. If any one of these is true for your
vehicle, then you need to change your oil and filter
every
3,000 miles (5 000 km) or 3 months -- whichever
occurs first. or
other commercial application.
If done of them is true, change the oil and filter every
7,500 miles (12 500 km) or 12 months -- whichever
occurs first. Driving a vehicle with a fully warmed
engine under highway conditions causes engine oil to
break down slower.
What to Do with Used Oil
Did YOU know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don’t let used oil stay on your skin
for very long. Clean your skin and nails with soap and
water,
or a good hand cleaner. Wash or properly throw
away clothing or rags containing used engine oil. (See
the manufacturer’s warnings about the use and disposal
of oil products.)
Used oil can be
a real threat to the environment. If you
change your own oil, be sure to drain all free-flowing oil
from the filter before disposal. Don’t ever dispose of oil
by putting it in the trash, pouring it
on the ground, into
sewers, or into streams
or bodies of water. Instead,
recycle it by taking
it to a place that collects used oil. If
you have a problem properly disposing
of your used oil,
ask your dealer, a service station or a local recycling
center for help.

When to Check and Change
A good time to check your automatic transmission fluid
level is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83
000 km) if the vehicle’s GVWR is over 8,600 or
if
the vehicle is mainly driven under one or more of
these conditions:
0 In heavy city traffic where the outside temperature
0 In hilly or mountainous terrain.
regularly reaches
90°F (32°C) or
higher.
0 When doing frequent trailer towing.
0 Uses such as found in taxi, police or delivery service.
If your vehicle’s
GVWR is not over 8,600 and you do
not use your vehicle under any
of these conditions, the
fluid and filter do
not require changing.
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 your GM dealer
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.
NOTICE:
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
parts or exhaust system parts, starting a fire. Be
sure to get an accurate reading if you check your
transmission
fluid.

Downloaded from www.Manualslib.com manuals search engine Engine Coolant
The cooling system in your vehicle is filled with new
DEX-COOL
TM (orange-colored, silicate-free) engine
coolant. This coolant is designed to remain
in your
vehicle for 5 years or 100,000 miles ( 166 000 km),
whichever occurs first.
The following explains your cooling system and how
to
add coolant when it is low. If you have a problem with
engine overheating, see “Engine Overheating” in
the Index.
A 5060 mixture of water and the proper coolant for
your vehicle will:
0 Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 “F ( 129 O C).
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
Let the warning lights and gages work as they should.
NOTICE:
When adding coolant it is important that you use
DEX-COOL TM (orange-colored, silicate-free)
coolant meeting
GM Specification 6277M.
If silicated coolant is added to the system,
premature engine, heater core or radiator
corrosion may result. In addition, the engine coolant
will require change sooner -- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first.

Downloaded from www.Manualslib.com manuals search engine What to Use
Use a mixture of one-half
clean water (preferably
distilled) and one-half DEX-COOL
Rul (orange-colored,
silicate-free) antifreeze that meets
GM Specification
6277M, which won’t damage aluminum parts. Use
GM Engine Coolant Supplement (sealer) (GM Part
No. 3634621) with any complete coolant change. If you
use this mixture, you don’t need
to add anything else.
’/d CAUTION:
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other
liquid like alcohol, can boil before the proper
coolant mix will. Your vehicle’s coolant warning
system
is set for the proper coolant mix. With
plain water or the wrong mix, your engine could
’ get too hot but you wouldn’t get the overheat
warning. Your engine could catch fire and you or
others could be burned. Use
a 50/50 mix of clean
water and
DEX-COOL TM (orange-colored,
silicate-free) antifreeze.

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.
Brake Wear
Your vehicle has front disc brakes and rear drum brakes.
Disc brake pads have built-in wear indicators that make a
high-pitched warning sound when the
brake pads are worn
and new pads are needed. The sound may come and
go or
be heard all the time your vehicle is moving (except when
you are pushing on the brake pedal firmly).
I
The brake wear warning sound means that
sooner or later your brakes won’t work well.
That could lead
to an accident. When you hear
the brake wear warning
sound, have your
vehicle serviced.
I NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.

Downloaded from www.Manualslib.com manuals search engine Using Solvent-’Qpe 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 a solvent:
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 a blow dryer
to help prevent a
cleaning ring.
Fabric Protection
Your GM has upholstery and carpet that has been treated
with Scotchgard” Fabric Protector, a
3M product. It
protects fabrics by repelling oil and water, which are the
carriers
of most stains. Even with this protection, you
still need to clean your upholstery and carpet often to
keep
it looking new.
Further information on cleaning is available by calling
1-800-433-3296
(in Minnesota, 1-800-642-6 167).
Special Cleaning Problems
Greasy or Oily Stains
Stains caused by grease, oil, butter, margarine, shoe
polish, coffee with cream, chewing gum, cosmetic
creams, vegetable oils, wax crayon, tar and asphalt can
be removed as follows:
1. Carefully scrape off excess stain.
2. Follow
the solvent-type instructions described earlier.
3. Shoe polish, wax crayon, tar and asphalt will stain if
left
on a vehicle’s seat fabric. They should be removed
as soon as possible. Be careful, because the cleaner will dissolve them and may cause them
to spread.
