13. Lower the vehicle by turning the wheel
wrench counterclockwise. Lower the jack
completely.
{CAUTION:
Incorrect wheel nuts or improperly
tightened wheel nuts can cause the wheel
to come loose and even come off. This
could lead to an accident. Be sure to use
the correct wheel nuts. If you have to
replace them, be sure to get new GM
original equipment wheel nuts. Stop
somewhere as soon as you can and have
the nuts tightened with a torque wrench to
the proper torque specication. See
Capacities and Specifications on page 457
for wheel nut torque specication.
Notice:Improperly tightened wheel nuts can
lead to brake pulsation and rotor damage.
To avoid expensive brake repairs, evenly
tighten the wheel nuts in the proper sequence
and to the proper torque specication. See
Capacities and Specifications on page 457for
the wheel nut torque specication.

Wood Panels
Use a clean cloth moistened in warm, soapy water
(use mild dish washing soap). Dry the wood
immediately with a clean cloth.
Speaker Covers
Vacuum around a speaker cover gently, so that
the speaker will not be damaged. Clean spots with
just water and mild soap.
Care of Safety Belts
Keep belts clean and dry.
{CAUTION:
Do not bleach or dye safety belts. If you
do, it may severely weaken them. In a
crash, they might not be able to provide
adequate protection. Clean safety belts
only with mild soap and lukewarm water.
Weatherstrips
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 frequent application may
be required. SeeRecommended Fluids and
Lubricants on page 473.
Washing Your Vehicle
The paint nish on the vehicle provides beauty,
depth of color, gloss retention, and durability.
The best way to preserve the vehicle’s nish is to
keep it clean by washing it often with lukewarm
or cold water.
Do not wash the vehicle in the direct rays of the
sun. Use a car washing soap. Do not use
strong soaps or chemical detergents. Be sure to
rinse the vehicle well, removing all soap
residue completely.

Approved cleaning products can be obtained from
your dealer. SeeVehicle Care/Appearance
Materials on page 444. Do not use cleaning agents
that are petroleum based, or that contain acid or
abrasives. All cleaning agents should be
ushed promptly and not allowed to dry on the
surface, or they could stain. Dry the nish 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 the vehicle.
Cleaning Exterior Lamps/Lenses
Use only lukewarm or cold water, a soft cloth and
a car washing soap to clean exterior lamps
and lenses. Follow instructions underWashing
Your Vehicle on page 439.
Finish Care
Occasional waxing or mild polishing of the vehicle
by hand may be necessary to remove residue
from the paint nish. Approved cleaning products
can be obtained from your dealer. SeeVehicle
Care/Appearance Materials on page 444.Notice:Machine compounding or aggressive
polishing on a basecoat/clearcoat paint
nish may damage it. Use only non-abrasive
waxes and polishes that are made for a
basecoat/clearcoat paint nish on your vehicle.
The vehicle has a basecoat/clearcoat paint
nish. 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 nish.
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 the vehicle’s
nish 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.
Exterior painted surfaces are subject to aging,
weather, and chemical fallout that can take their
toll over a period of years. To help keep the
paint nish looking new, keep the vehicle in a
garage or covered whenever possible.

Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your dealer
rst. Some electrical equipment can damage
your vehicle and the damage would not
be covered by your warranty. Some add-on
electrical equipment can keep other
components from working as they should.
Add-on equipment can drain your vehicle’s battery,
even if your vehicle is not operating.
Your vehicle has an airbag system. Before
attempting to add anything electrical to your
vehicle, seeServicing Your Airbag-Equipped
Vehicle on page 88.
Windshield Wiper Fuses
The windshield wiper motor is protected by an
internal circuit breaker. If the wiper motor
overheats due to heavy snow, the wipers will stop
until the motor cools and will then restart.
Power Windows and Other Power
Options
Circuit breakers protect the power windows and
power seats. When the current load is too
heavy, the circuit breaker opens and closes,
protecting the circuit until the problem is xed or
goes away.
446

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected
from short circuits by a combination of fuses
and circuit breakers. This greatly reduces
the chance of res caused by electrical problems.
Look at the silver-colored band inside the fuse.
If the band is broken or melted, replace the fuse.
Be sure you replace a bad fuse with a new
one of the identical size and rating. If a fuse blows,
see your dealer for service immediately.
If you ever have a problem on the road and don’t
have a spare fuse, you can “borrow” one that has
the same amperage. Pick some feature of your
vehicle that you can get along without – like the
radio or cigarette lighter – and use its fuse, if it is the
correct amperage. Replace it as soon as you can.
The fuses are located in three fuse blocks,
one located in the engine compartment on the
passenger’s side and the other two under the
rear seat.
Underhood Fuse Block
The underhood fuse block is located in the engine
compartment on the passenger’s side of the
vehicle. SeeEngine Compartment Overview on
page 342for more information on location.
To access the fuses, push in the two tabs located
on each side of the fuse block cover. Then lift
the cover off.

Using the Maintenance Schedule
We at General Motors want to help you keep your
vehicle in good working condition. But we do
not know exactly how you will drive it. You may
drive very short distances only a few times a week.
Or you may drive long distances all the time in
very hot, dusty weather. You may use your vehicle
in making deliveries. Or you may drive it to
work, to do errands, or in many other ways.
Because of all the different ways people use their
vehicles, maintenance needs vary. You may
need more frequent checks and replacements.
So please read the following and note how
you drive. If you have any questions on how to
keep your vehicle in good condition, see your
GM Goodwrench
®dealer.
This schedule is for vehicles that:
carry passengers and cargo within
recommended limits. You will nd these limits

genuine GM parts.Scheduled Maintenance
When the Change Engine Oil message in the
Driver Information Center (DIC) comes on,
it means that service is required for your vehicle.
Have your vehicle serviced as soon as possible
within the next 600 miles (1 000 km). It is possible
that, if you are driving under the best conditions,
the engine oil life system may not indicate
that vehicle service is necessary for over a year.
However, your engine oil and lter must be
changed at least once a year and at this time the
system must be reset. Your GM Goodwrench
®
dealer has GM-trained service technicians who will
perform this work using genuine GM parts and
reset the system.
If the engine oil life system is ever reset
accidentally, you must service your vehicle within
3,000 miles (5 000 km) since your last service.
Remember to reset the oil life system whenever
the oil is changed. SeeEngine Oil Life System on
page 349for information on the Engine Oil Life
System and resetting the system.
