Service All-Wheel Drive Light
S IC
AWD
United States Canada
This light should come on briefly when you turn on the
ignition, as a check to show you
it is working.
The SERVICE AWD light comes on
to indicate that
there may be a problem with the drive system and
service is required. Malfunctions can be indicated by the
system before any problem is apparent, which may
prevent serious damage
to the vehicle. This system is
also designed
to assist your service technician in
correctly diagnosing a malfunction.
Check Gages Warning Light
CHECK
GAGES
1 United States J
Canada
The CHECK GAGES light will come on briefly when you
are starting the engine.
If the light comes on and stays on while you are driving,
check your coolant temperature and engine oil pressure gages
to see if they are in the warning zones.

Anti-lock Brake System
Your vehicle has anti-lock brakes. ABS is an advanced
electronic braking system that will help prevent a
braking skid.
When you start your engine and begin to drive away,
your anti-lock brake system will check itself. You
may hear a momentary motor or clicking noise while
this test
is going on. This is normal.
If there’s a problem with
~ the anti-lock brake system,
~ this warning light will
stay on. See
Anti-Lock
Brake System Warning
Light
on page 3-34.
Along with ABS, your vehicle has a Dynamic Rear
Proportioning (DRP) system. If there’s a DRP problem,
both the brake and ABS warning lights will come on
accompanied by a IO-second chime. The lights
and chime will come on each time the ignition
is turned
on until the problem is repaired. See your dealer for
service. Let’s say the
road is wet and you’re driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here’s what
happens with ABS:
A computer senses that wheels are slowing down. If
one of the wheels is about to stop rolling, the computer
will separately work the brakes at each front wheel
and at both rear wheels.

Once you are moving on the freeway, make certain you
allow a reasonable following distance. Expect to
move slightly slower at night.
When you want to leave the freeway, move to the
proper lane well in advance.
If you miss your exit, do
not, under any circumstances, stop and back up. Drive
on to the next exit.
The exit ramp can be curved, sometimes quite sharply.
The exit speed is usually posted.
Reduce your speed according to your speedometer, not
to your sense of motion. After driving for any distance
at higher speeds, you may tend to think you are
going slower than you actually are.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you
must start when you’re not fresh
- such as after a day’s
work
- don’t plan to make too many miles that first
part of the journey. Wear comfortable clothing and shoes
you can easily drive in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained, it’s ready to go. If it needs
service, have it done before starting out. Of course,
you’ll find experienced and able service experts
in dealerships all across North America. They’ll be
ready and willing to help
if you need it.
Here are some things you can check before a trip:
e
0
e
Windshield Washer Fluid: Is the reservior full? Are
all windows clean inside and outside?
Wiper Blades: Are they in good shape?
Fuel, Engine Oil, Other Fluids: Have you checked
all levels?
Lamps: Are they all working? Are the lenses clean?
Tires: They are vitally important to a safe,
trouble-free trip.
Is the tread good enough for
long-distance driving? Are the tires all inflated to the
recommended pressure?
Weather Forecasts: What’s the weather outlook
along your route? Should you delay your trip a
short time to avoid a major storm system?
Maps: Do you have up-to-date maps?
4-33

Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make
body insulators from newspapers, burlap bags, rags,
floor mats
- anything you can wrap around
yourself or tuck under your clothing to keep warm.
-.-
You can run the engine to keep warm, but be careful. Snow can trap ~,,raust
,,ses u..,er your
vehicle. This can cause deadly
CO (carbon
monoxide) gas to get inside.
CO could
overcome you and
kill you. You can’t see it or
smell
it, so you might not know it is in your
vehicle. Clear away snow from around the
base of your vehicle, especially any that is
blocking your exhaust pipe. And check around
again from time to time to be sure snow
doesn’t collect there.
Open a window
just a little on the side of the
vehicle that’s away from the wind. This will
help keep
CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little
faster than just idle. That is, push the accelerator
slightly. This uses less fuel for the heat that you get and
it keeps the battery charged. You will need a
well-charged battery to restart the vehicle, and possibly
for signaling later on with your headlamps. Let the
heater run for a while.

As in the chart shown previously, SAE 5W-30 is the
only viscosity grade recommended for your vehicle. You
should look for and use only oils which have the API
Starburst symbol and which are also identified as
SAE 5W-30.
If you cannot find such SAE 5W-30 oils,
you can use an SAE IOW-30 oil which has the API
Starburst symbol,
if it's going to be 0°F (-18°C)
or above. Do not use other viscosity grade oils, such as
SAE IOW-40 or SAE 20W-50 under any conditions.
Notice: Use only engine oil with the American
Petroleum Institute Certified For Gasoline Engines
starburst symbol. Failure to use the recommended
oil can result in engine damage not covered by
your warranty.
GM Goodwrench@ oil meets all the requirements for
your vehicle.
If you are in an area of extreme cold, where the
temperature falls below -20°F (-29"C), it is
recommended that you use either an SAE 5W-30
synthetic
oil or an SAE OW-30 oil. Both will provide
easier cold starting and better protection for your engine
at extremely low temperatures.
Engine Oil Additives
Don't add anything to your oil. The recommended oils
with the starburst symbol are all you will need for
good performance and engine protection.
When to Change Engine Oil
(GM Oil Life System)
Your vehicle has a computer system that lets YO
when to change the engine oil-and filter. This is
IU know
based on engine revolutions and engine temperature,
and not on mileage. Based on driving conditions,
the mileage at which an oil change will be indicated can
vary considerably. For the oil life system to work
properly, you must reset the system every time the oil is
changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change
is
necessary. A CHANGE ENG OIL light in the Driver
Information Center (DIC) will come on. Change your oil
as soon
as possible within the next two times you
stop for fuel. It is possible that,
if you are driving under
the best conditions, the oil life system may not
indicate that an oil change is necessary for over a year.
However, your engine oil and filter must be changed
at least once a year and at this time the system must be
reset. It is also important to check your oil regularly
and keep it at the proper level.
If the system is ever reset accidentally, you must
change your oil at 3,000 miles (5
000 km) since your
last oil change. Remember to reset the oil life system
whenever the oil is changed.

How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transmission fluid
to use. See Part D:
Recommended Fluids and Lubricants on page 6- 17.
Add fluid only after checking the transmission fluid while
it is hot.
(A cold check is used only as a reference.) If
the fluid level is low, add only enough of the proper fluid
to bring the level up
to the HOT area for a hot check.
It doesn’t take much fluid, generally less than one
pint (0.5 L).
Don’t overfill.
Notice: We recommend you use only fluid labeled
DEXRON@
-111, because fluid with that label is
made especially for your automatic transmission.
Damage caused by fluid other than DEXRON@
-111 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.
Engine Coolant
The cooling system in your vehicle is filled with
DEX-COOL@ engine coolant. This coolant is designed
to remain in your vehicle for 5 years or 150,000 miles
(240 000 km), whichever occurs first, if you add
only DEX-COOL@ extended life 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 on
page 5-24.
A 50/50 mixture of clean, drinkable water and
DEX-COOL@ coolant will:
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
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 only
DEX-COOL@ (silicate-free) coolant.
If coolant other than DEX-COOL@ 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.
Damage caused by the
use of coolant other
than DEX-COOL@
is not covered by your new
vehicle warranty.

Scheduled Maintenance
The services shown in this schedule up to 100,000 miles
(166 000 km) should be repeated after 100,000 miles
(166 000 km) at the same intervals for the life of
this vehicle. The services shown at
150,000 miles
(240 000 km) should be repeated at the same interval
after
150,000 miles (240 000 km) for the life of this
vehicle.
See
Part B: Owner Checks and Services on page 6- 10
and Part C: Periodic Maintenance Inspections on
page 6- 15.
Footnotes
t The US. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emission warranty or limit recall liability prior
to
the completion of the vehicle 's useful life. We, however,
urge that all recommended maintenance services be
performed at the indicated intervals and the
maintenance be recorded.
+ A good time to check your brakes is during tire
rotation. See Brake System Inspection
on page 6- 16.
Engine Oil Scheduled Maintenance
Change engine oil and filter as indicated by the GM
Oil Life System (or every 12 months, whichever
occurs first). Reset the system.
Your vehicle has a computer system that lets you know
when
to change the engine oil and filter. This is
based on engine revolutions and engine temperature,
and not on mileage. Based on driving conditions,
the mileage
at which an oil change will be indicated can
vary considerably. For the
oil life system to work
properly, you must reset the system every time the oil is
changed.
When the system has calculated that oil life has been
diminished, it will indicate that an oil change is
necessary. A CHANGE ENGINE
OIL light will come on.
Change your oil as soon as possible within the next
two times you stop for fuel. It is possible that,
if you are
driving under the best conditions, the oil life system
may not indicate that an oil change is necessary for over
a year. However, your engine oil and filter must be
changed at least once a year and at this time the system
must be reset.
It is also important to check your oil
regularly and keep
it at the proper level.
If the system is ever reset accidentally, you must
change your oil at
3,000 miles (5 000 km) since your
last oil change. Remember
to reset the oil life system
whenever the oil is changed. See
Engine Oil on
page 5-13 for information on resetting the system.
After the services are performed, record the date, odometer reading and who performed the service on the
maintenance record pages in Part
E of this schedule.

At Least Twice a Year
Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages
are working properly. Look for any other loose or
damaged safety belt system parts. If you see anything
that might keep a safety belt system from doing its
job, have it repaired. Have any torn or frayed safety belts
replaced.
Also look for any opened or broken air bag coverings,
and have them repaired or replaced. (The air bag
system does not need regular maintenance.)
Wiper Blade Check
Inspect wiper blades for wear or cracking. Replace
blade inserts that appear worn or damaged or that
streak or miss areas of the windshield.
Also see
Cleaning the Outside of Your Vehicle on page 5-80.
Spare Tire Check
At least twice a year, after the monthly inflation check of
the spare tire determines that the spare is inflated
to
the correct tire inflation pressure, make sure that
the spare tire is stored securely. Push, pull, and then try
to rotate or turn the tire. If it moves, use the wheel
wrenchhatchet
to tighten the cable. See Changing a Flat
Tire on page
5-62.
Engine Air Cleaner Filter Restriction
Indicator Check
Your vehicle may be equipped with an engine air
cleaner filter restriction indicator located on the air
cleaner in the engine compartment. The indicator lets
you know when the air cleaner filter is dirty and needs
to
be changed. Check the indicator at least twice a year
or when your engine oil is changed, whichever
occurs first. See
Engine Air Cleaner/Fi/fer on page 5-18
for more information. Inspect your air cleaner filter
restriction indicator more often
if the vehicle is used in
dusty areas or under
off road conditions.
Weatherstrip Lubrication
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth. During very cold,
damp weather more frequent application may be required. See
Part D: Recommended Fluids and
Lubricants on page
6-17.
Automatic Transmission Check
Check the transmission fluid level; add if needed. See
Automatic Transmission Fluid on page 5-20. A fluid loss
may indicate a problem. Check the system and repair
if needed.
