How to Reset the Change Engine Oil
Message
The GM Oil Life System calculates when to change your
engine oil and ®lter based on vehicle use. Anytime your
oil is changed, reset the system so it can calculate when
the next oil change is required. If a situation occurs where
you change your oil prior to a CHANGE ENGINE OIL
message being turned on, reset the system.
1. With the ignition key in RUN but the engine off,
repeatedly push the trip/reset button until OIL is
displayed on the Driver Information Center (DIC).
2. Once OIL is displayed, push and hold the trip/reset
button for ®ve seconds. The number will disappear
and be replaced by 100 (indicating 100% oil life
remaining).
3. Turn the key to OFF.
If the CHANGE ENGINE OIL message comes back on
when you start your vehicle, the engine oil life system
has not reset. Repeat the procedure.
What to Do with Used Oil
Used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer.
Do not 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 dispose
of 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 threat to the environment. If you
change your own oil, be sure to drain all the oil from
the ®lter before disposal. Never 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.

Power Steering Fluid
When to Check Power Steering Fluid
It is not necessary to regularly check power steering ¯uid
unless you suspect there is a leak in the system or
you hear an unusual noise. A ¯uid loss in this system
could indicate a problem. Have the system inspected
and repaired. See
Engine Compartment Overview
on page 5-12for reservoir location.
How to Check Power Steering Fluid
Turn the key off, let the engine compartment cool down,
wipe the cap and the top of the reservoir clean, then
unscrew the cap and wipe the dipstick with a clean rag.
Replace the cap and completely tighten it. Then remove
the cap again and look at the ¯uid level on the dipstick.
When the engine compartment is hot, the level should
be at the H (hot) mark. When it's cold, the level
should be at the C (cold) mark. If the ¯uid is at the
ADD mark, you should add ¯uid.
What Power Steering Fluid to Use
To determine what kind of ¯uid to use, seeRecommended Fluids and Lubricants on page 6-12.
Always use the proper ¯uid. Failure to use the proper
¯uid can cause leaks and damage hoses and seals.

Removing the Wheel Covers
If the wheel has a center cap, use the handle of the
folding wrench to pry it off. Then, with the other end of
the folding wrench, loosen the nuts.
If your vehicle has the plastic bolt-on wheel covers,
loosen the bolts completely using the folding wrench,
and remove the wheel cover.
Removing the Flat Tire and Installing
the Spare Tire
1. Loosen the wheel
nuts Ð but do not
remove them Ð using
the folding wrench.
Turn the handle about
180 degrees, then
¯ip the handle back to
the starting position.
This avoids taking
the wrench off the
lug nut for each turn.
For wheels with a wheel lock key, use the wheel
lock key between the lock nut and folding wrench.
The key is supplied in the front passenger door
pocket.
Notice:If your vehicle has wheel locks and you
use an impact wrench to remove the wheel
nuts, you could damage the lock nut or wheel lock
key. Do not use an impact wrench to remove
the wheel nuts if your vehicle has wheel locks.

(c)Visually inspect hoses and have them replaced if they
are cracked, swollen or deteriorated. Inspect all pipes,
®ttings and clamps; replace with genuine GM parts as
needed. To help ensure proper operation, a pressure test
of the cooling system and pressure cap and cleaning the
outside of the radiator and air conditioning condenser is
recommended at least once a year.
(d)Visually inspect wiper blades for wear or cracking.
Replace blade inserts that appear worn or damaged
or that streak or miss areas of the windshield.
(e)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.)
(f)Lubricate all key lock cylinders, hood latch
assemblies, secondary latches, pivots, spring anchor
and release pawl, hood and door hinges, rear folding
seats, liftgate hinges, fuel door hinge, power sliding door
cable and sliding door track(s). More frequent lubrication
may be required when exposed to a corrosive
environment. Applying silicone grease on weatherstrips
with a clean cloth will make them last longer, seal
better and not stick or squeak.
(g)If you drive regularly under dusty conditions, the
®lter may require replacement more often.
(h)Change automatic transaxle ¯uid and ®lter if the
vehicle is mainly driven under one or more of these
conditions:
þIn heavy city traffic where the outside temperature
regularly reaches 90ÉF (32ÉC) or higher.
þIn hilly or mountainous terrain.
þWhen doing frequent trailer towing.
þUses such as found in taxi, police or delivery
service.
(i)Drain, ¯ush and re®ll cooling system. See Engine
Coolant on page 5-22for what to use. Inspect hoses.
Clean radiator, condenser, pressure cap and ®ller neck.
Pressure test the cooling system and pressure cap.
(j)
Check system for interference or binding and
for damaged or missing parts. Replace parts as needed.
Replace any components that have high effort or
excessive wear. Do not lubricate accelerator or cruise
control cables.
(k)A ¯uid loss in any vehicle system could indicate a
problem. Have the system inspected and repaired
and the ¯uid level checked. Add ¯uid if needed.

At Least Once a Year
Starter Switch Check
{CAUTION:
When you are doing this inspection, the
vehicle could move suddenly. If the vehicle
moves, you or others could be injured.
1. Before you start, be sure you have enough room
around the vehicle.
2. Firmly apply both the parking brake and the regular
brake. See
Parking Brake on page 2-37if
necessary.
Do not use the accelerator pedal, and be ready to
turn off the engine immediately if it starts.
3. Try to start the engine in each gear. The starter
should work only in PARK (P) or NEUTRAL (N).
If the starter works in any other position, contact
your GM Goodwrench dealer for service.
Automatic Transaxle Shift Lock Control
System Check
{CAUTION:
When you are doing this inspection, the
vehicle could move suddenly. If the vehicle
moves, you or others could be injured.
1. Before you start, be sure you have enough room
around the vehicle. It should be parked on a level
surface.
2. Firmly apply the parking brake. See
Parking Brake
on page 2-37if necessary.
Be ready to apply the regular brake immediately if
the vehicle begins to move.
3. With the engine off, turn the key to the RUN
position, but do not start the engine. Without
applying the regular brake, try to move the shift
lever out of PARK (P) with normal effort. If the shift
lever moves out of PARK (P), contact your GM
Goodwrench dealer for service.
