SAE 15W-40
As shown in the viscosity chart, SAE 15W-40 is best for your vehicle.
However, you can use
SAE 1OW-30 if it’s going to be colder than
32°F (0°C) before your next oil change. When it’s very cold, below
0°F (-I 8OC), you should use SAE 1,0W-30 to improve cold starting.
Also, SAE 30 may be used at temperatures above freezing, 32°F (0°C).
These numbers on the oil container show its viscosity, or thickness. Do
not use other viscosity oils such as SAE 10W-40 or SAE 2OW-50.

you select the correct oil.
You should look for this on
the oil container, and use only those oils that
display
the logo.
GM Goodwrench@ oil
(in Canada, GM Engine Oil) meets all the
requirements for your vehicle.
Engine Oil Additives
Don’t add anything to your oil. Your GM dealer is ready to advise if you
think something should be added.
When to Change Engine Oil
See if any one of these is true for you:
0 Most trips are less than 4 miles (6 km).
0 It’s below freezing outside and most trips are less than 10 miles
(16 km).
0 The engine is at low speed most of the time (as in door-to-door
delivery, or in stop-and-go traffic).
0 You tow a trailer often.
0 Most trips are through dusty places.
The vehicle is frequently operated off-road.
If any
of these is true for your vehicle, then you need to change your oil and
filter
every 2,500 miles (4 000 km) or 3 months - whichever comes first.
If
none of them is true, change the oil and filter every 5,000 miles
(8 000 km) or 12 months - whichever comes first.
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.

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 choose to have this
done at
a GM dealership Service Department.
If you do it yourself, be SLIK to follow all the instructions here, or you could
get a false reading on the dipstick.

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 tluid, generally less than a pint. Don’t overfill. We
recommend you use only fluid labeled DEXRON@-111 or DEXRON@-IIE,
because fluids with that label are made especially for your automatic
transmission. Damage caused by fluid other than
DEXRON@-Ill or
DEXRON@-IIE is not covered by your new vehicle warranty.
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; then flip the handle down to lock the dipstick in place.
Manual Fluid
When to Check
A good time to have it checked is when the engine oil is changed. However,
the fluid
in your manual transmission doesn’t require changing.
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.
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, starting a fire. Be sure to get
an accurate reading if
you check your transmission fluid.
Check the fluid level only when your engine is off, the vehicle is parked on
a level place and the transmission is cool enough for you to rest your fingers
on the transmission case.

What to use
Refer to the Maintenance Schedule to determine what kind of lubricant to
use. See “Recommended Fluids and Lubricants”
in the Index.
Engine Coolant
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.
The proper coolant for your vehicle
will:
Give freezing protection down to -20 OF (-29”C), or -34°F (-37°C) in
Canada and for vehicles with the cold climate option.
Give boiling protection up to 258 OF ( 125 O C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they should.
What to Use
Use a mixture of one-half clean wuter (preferably distilled) and one-half
antifreeze that meets
“GM Specification 6038-M,” which won’t damage
aluminum parts.
You can also use a recycled coolant conforming to “GM
Specification 6038-M” with a complete coolant flush and refill. If you use
this mixture, you don’t need to add anything else.

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, and always clean the brake fluid reservo\
ir cap before
removing it.
NOTICE:
Don’t let someone put in the wrong kind of fluid. 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.
Brake fluid can damage paint, so be careful not to spill brake
fluid
on your vehicle. If you do, wash it off immediately. See
“Appearance Care” in the Index.

Fluid Leak Check
After the vehicle has been parked for a while, inspect the surface under the
vehicle for water, oil, fuel or other fluids. Water dripping from the air
conditioning
system after it has been used is normal. If you notice fuel leaks
or fumes, the causes should be found and corrected at once.
Lubrication
Accelerator Control System
Your maintenance schedule will tell you how often the accelerator linkage
pivot points must be lubricated. See “Recommended
Fluids and Lubricants”
in the Tndex for the proper lubricant to use.
Accelerator cables and cruise control cables should not be lubricated.
Any
cab1e.s that are worn or are hard to pull should be replaced.
Hood Latches and Hood Hinge
Your 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
See your maintenance schedule to find out 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
See your mamtenance schedule to find out how often the constant velocity
joints must be lubricated. See “Recommended Flui-ds and Lubricants”
in the
Index for the proper lubricant to use.
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.
For exposed surfaces, such as door checks, door lock bolts, lock striker
plates, dovetail bumper wedges, etc., a
thin film of engine oil should be
applied.
The seat adjusters and seat track should be lubricated
with chassis grease.
Door weather strips and rubber hood bumpers should be wiped clean with
a
rubber lubricant.

Never use too much of any lubricant and be sure to wipe up any extra
lubricant when
you are finished.
Your maintenance schedule
will tell you how often to lubricant these items.
See “Recommended Fluids and Lubricants”
in the Index for the proper
lubricant
to use.
Lock Cylinders
To be sure your locks operate properly, they must be lubricated. Your
vehicle’s 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 the 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.
Tailgate Handle
The tailgate handle pivot points on your vehicle should be lubricated to keep
the handle working smoothly.
Your maintenance schedule
will tell you how often to lubricant the handle.
See “Recommended Fluids and Lubricants” in the Index for the proper
lubricant to use.
Battery
Every new GM 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 catalog number shown on
the original battery’s label.
Vehicle Storage
If you’re not going to drive your vehicle for 25 days or more, take off the
black, negative (-) cable from the battery. This will help keep your battery
from running down.

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 a solvent:
0 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.
0 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
the previous NOTICE.)
Fabric Protection
Your vehicle has upholstery and trim carpet that has been treated with
Scotchgard
TM Fabric Protector, a 3M product. Scotchgard TM 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 trim 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
Such as grease, oil, butter, margarine, shoe polish, coffee with cream,
chewing gum, cosmetic creams, vegetable oils, wax crayon, tar and asphalt.
0 Carefully scrape off excess stain.
Follow the solvent-type instructions described earlier.
0 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 spread.
Non-Greasy Stains
Such as 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.
0 If a stain remains, follow the foam-type instructions described earlier.
