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
If any one of these is true for you. use the short tripkity

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).
You operate
your vehicle in dusty areas or
off-road frequently.
You frequently tow
a trailer or use a currier on top of
your vehicle.
The vehicle is used for delivery service. police, taxi
or other commercial application. 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
occllrs first.
If none of them is true, use the long trip/highway
maintenance schedule. 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.
Remote Oil Filter (Four-wheel Drive)
The access door for the remote oil filter is in the steering
linkage shield assembly located under the radiator
support.
Twist the screw to unlock or lock the door.
Make sure
if you open the door. it is securely closed
when
~OLI are finished.

Operating the engine with the air cleaner off can
cause you or others to be burned. The air cleaner
not only cleans the
air, it stops flame if the engine
backfires.
If it isn’t there, and the engine
backfires, you could be burned. Don’t drive with
it
off, and be careful working on the engine with
the air cleaner
off.
NOTICE:
If the air cleaner is off, a backfire can cause a
damaging engine fire. And, dirt can easily get
into your engine, which will damage
it. Always
have the air cleaner in place when you’re driving.
Automatic Transmission Fluid
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
(53 000 km) if the vehicle is mainly driven under one or
more
of these conditions:
In heavy city traffic where the outside temperature
regularly reaches
90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi. police or delivery service.
If 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.

Downloaded from www.Manualslib.com manuals search engine Checking Transmission Fluid Cold
A cold check is made after the vehicle has been sitting
for eight hours or more with
the engine off and is used
only as a reference. Let the engine run at idle for five
minutes
if outside temperatures are 50°F ( 10°C) or
more.
If it's colder than 50°F (IOOC), you may have to
idle the engine longer. Should the fluid level be low
during
a cold check. you mrrst perform a hot check
before adding fluid. This
will give you a more accurate
reading
of the fluid level.
Checking the Fluid Hot or Cold
0 Park your \.tthicle on a level place. Keep the
engine
running.
0 With the parking brake applied. place the shift lever
in PARK (P).
Then, without shutting off the engine, follow these steps:
1. Flip the handle up and then pull out the dipstick and
wipe
it with a clean rag or paper towel.
2. Push it back in all the way, wait three seconds and
then
p~dl it back out again.

If your vehicle has a compact spare tire, don’t include it
in your tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the
CertificationRire label. Make certain that all wheel nuts
are properly tightened. See “Wheel
Nut Torque” in
the Index.
Rust or dirt on a wheel, or on the parts to which
it
is fastened, can make wheel nuts become loose
after a time. The wheel could come off and cause
an accident. When
you change a wheel, remove
any rust or dirt from places where the wheel
attaches to the vehicle.
In an emergency, you can
use a cloth or a paper towel to do this; but
be
sure to use a scraper or wire brush later, if you
need to, to get all the rust or dirt off. (See
“Changing a Flat Tire”
in the Index.)

Use suds only and apply with a clean sponge. Don‘t
saturate the material and don’t rub
it roughly.
As soon as you’ve cleaned the section, use a sponge
to remove the suds.
Rinse the section with a clean, wet sponge.

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:
1. Gently scrape excess soil from the trim material with
a clean. dull knife or scraper.
2. Use very little cleaner, light pressure and clean cloths
(preferably cheesecloth). Cleaning should start at the
outside
of the stain, “feathering” toward the center.
3. Keep changing to a clean section of the cloth.
4. When you clean it stain from fabric. immediately
dry the area
with a blow dryer to help prevent a
cleaning
ring.

Downloaded from www.Manualslib.com manuals search engine 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 (mild detergent)
soaps.
Don’t use cleaning agents that are petroleum based, or
that contain acid or abrasives. All cleaning agents
should be flushed promptly and not allowed to dry on
the surface, or they could stain. Dry the finish with
a
soft, clean chamois or an all-cotton towel to avoid
surface scratches and water spotting.
High pressure car washes may cause water to enter
your vehicle.
Finish Care
Occasional waxing or mild polishing of your vehicle by
hand may be necessary to remove residue from the paint
finish.
You can get GM-approved cleaning products
from your dealer.
(See “Appearance Care and Materials”
in the Index.)
Your vehicle has a “basecoat/clearcoat” paint finish. The
clearcoat gives more depth and gloss to the colored
basecoat. Always use waxes and polishes that are
non-abrasive and made for a basecoat/clearcoat
paint finish.
I NOTICE:
Machine compounding or aggressive polishing on
a basecoatklearcoat paint finish
may dull the
finish or leave swirl marks.
Cleaning Exterior LampsLenses
Use lukewarm or cold water, a soft cloth and a liquid
hand, dish or car washing
(mild detergent) soap to clean
exterior lamps and lenses. Follow instructions under
“Washing Your Vehicle.“ Foreign materials
such as calcium chloride and other
salts. ice melting agents, road oil and tar, tree sap, bird
droppings. chemicals from industrial chimneys, etc.. can
damage your vehicle’s finish
if they remain on painted
surfaces. Wash the vehicle as soon as possible.
If
necessary, use non-abrasive cleaners that are marked
safe for painted surfaces
to remove foreign matter.
6-54

Downloaded from www.Manualslib.com manuals search engine Exterior painted surfaces are subject to aging, weather
and chemical faIIout that can take their toll over a period
of years. You can help to keep the paint finish looking
new by keeping your vehicle garaged or covered
whenever possible.
Protecting Exterior Bright Metal Parts
Bright metal parts should be cleaned regularly to keep
their luster. Washing with water is all that is usually
needed. However, you may use chrome polish on
chrome
or stainless steel trim, if necessary.
Use special care with aluminum trim. To avoid
damaging protective trim, never use auto or chrome
polish, steam or caustic soap
to clean aluminum. A
coating of wax, rubbed to high polish, is recommended
for all bright metal parts.
Cleaning Aluminum Wheels
(If Equipped)
Keep your wheels clean using a soft clean cloth with
mild
soap and water. Rinse with clean water. After
rinsing thoroughly, dry with
a soft clean towel. A wax
may then be applied. The surface
of these wheels is
similar to the painted
surface
of your vehicle. Don’t use strong soaps,
chemicals, abrasive polishes, abrasive cleaners or
abrasive cleaning brushes on them because
you could
damage the surface.
Don’t take your vehicle through an automatic car wash
that has silicon carbide tire cleaning brushes. These
brushes can also damage the surface
of these wheels.
Cleaning Tires
To clean your tires, use a stiff brush with a tire cleaner.
I NOTICE:
When applying a tire dressing always take care to
wipe
off any overspray or splash from all painted
surfaces on the body or wheels
of the vehicle.
Petroleum-based products may damage the
paint finish.
Sheet Metal Damage
If your vehicle is damaged and requires sheet metal
repair or replacement, make sure the body repair shop
applies anti-corrosion material
to the parts repaired or
replaced to restore corrosion protection.
