6-15 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.
Engine Air Cleaner/Filter
The engine air cleaner/filter is located behind the
headlamps on the passenger's side of the engine.
See ªEngine Compartment Overviewº in the Index
for more information on location. Be sure the engine has
cooled before following these steps to replace the engine
air cleaner/filter.

6-31 High Intensity Discharge (HID) Lighting
(If Equipped)
CAUTION:
The low beam High Intensity Discharge lighting
system operates at a very high voltage. If you try
to service any of the system components, you
could be seriously injured. Have your dealer or a
qualified technician service them.
Halogen Bulbs
CAUTION:
Halogen bulbs have pressurized gas inside and
can burst if you drop or scratch the bulb. You or
others could be injured. Be sure to read and
follow the instructions on the bulb package.
Headlamps
1. With a screwdriver, unscrew the fastener on the
headlamp cover and then remove the cover to gain
access to the headlamps. Note that the inner bulb is
for the high
-beam headlamp and the outer bulb is for
the low
-beam headlamp.

6-34
Headlamp Aiming
If your vehicle is damaged in an accident, the headlamp
aim may be affected. Aim adjustment to the low beam
may be necessary if it is difficult to see lane markers
(for horizontal aim), or if oncoming drivers flash their
high beams at you (for vertical aim). If you believe your
headlamps need to be re
-aimed, we recommend that you
take your vehicle to the dealer for service. However, it is
possible for you to re
-aim your headlamps by following
the procedure in the service manual for your vehicle.
NOTICE:
To make sure your headlamps are aimed
properly, read all the instructions before
beginning. Failure to follow these instructions
could cause damage to headlamp parts.
Front Turn Signal Lamp
1. With a screwdriver, unscrew the fastener on the
headlamp cover and then remove it to access the
turn signal lamps.

6-35
2. On the outboard side of each low-beam headlamp,
you will find the turn signal bulbs. Turn the lamp
assembly counterclockwise to remove it.3. Pull the bulb out, replace it and then reassemble.
Taillamp and Stop Lamp
1. Open the trunk to access the lamp housing.
2. Depending on which outer bulb needs replacing,
open either the spare tire cover on the driver's side or
the storage compartment on the passenger's side to
access the bulbs.

6-45
Each new wheel should have the same load-carrying
capacity, diameter, width, offset and be mounted the
same way as the one it replaces.
If you need to replace any of your wheels or wheel
bolts, replace them only with new GM original
equipment parts. This way, you will be sure to have the
right wheel and wheel bolts for your vehicle.
CAUTION:
Using the wrong replacement wheels and wheel
bolts on your vehicle can be dangerous. It could
affect the braking and handling of your vehicle,
make your tires lose air and make you lose
control. You could have a collision in which you
or others could be injured. Always use the correct
wheel and wheel bolts for replacement.
NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper
height, vehicle ground clearance and tire or tire
chain clearance to the body and chassis.
See ªChanging a Flat Tireº in the Index for
more information.
Used Replacement Wheels
CAUTION:
Putting a used wheel on your vehicle is
dangerous. You can't know how it's been used or
how far it's been driven. It could fail suddenly
and cause an accident. If you have to replace a
wheel, use a new GM original equipment wheel.

6-56
Electrical System
Add-On Electrical Equipment
NOTICE:
Don't add anything electrical to your vehicle
unless you check with your dealer first. Some
electrical equipment can damage your vehicle
and the damage wouldn't be covered by your
warranty. Some add
-on electrical equipment
can keep other components from working as
they should.
Your vehicle has an air bag system. Before attempting to
add anything electrical to your vehicle, see ªServicing
Your Air Bag
-Equipped Vehicleº in the Index.
Headlamp Wiring
The headlamp wiring has several fuses which are
powered by a MaxiFuse
. An electrical overload will
cause the lamps to go on and off, or in some cases to
remain off. If this happens, have the headlamp wiring
checked right away.
Windshield Wiper Fuses
If the windshield wiper motor overheats due to heavy
snow or ice, the wipers will stop until the motor cools.
If the overload is caused by some electrical problem, be
sure to have it fixed.
Power Windows and Other Power Options
Circuit breakers protect the power windows and other
power accessories. When the current load is too heavy,
the circuit breaker opens and closes, protecting the
circuit until the problem is fixed or goes away.
