Bulb Replacement
For the proper type of replacement bulb, seeReplacement Bulbs on page 5-61.
For any bulb changing procedure not listed in this
section, contact your dealer.
High Intensity Discharge (HID)
Lighting
{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 quali®ed technician service them.
Your vehicle may have HID headlamps. After your
vehicle's HID headlamp bulb has been replaced, you
may notice that the beam is a slightly different
shade than it was originally. This is normal.

{CAUTION:
Mixing tires could cause you to lose control
while driving. If you mix tires of different sizes
or types (radial and bias-belted tires), the
vehicle may not handle properly, and you
could have a crash. Using tires of different
sizes may also cause damage to your vehicle.
Be sure to use the same size and type tires on
all wheels. It's all right to drive with your
compact spare temporarily, it was developed
for use on your vehicle. See ªCompact Spare
Tireº in the index.
{CAUTION:
If you use bias-ply tires on your vehicle, the
wheel rim ¯anges could develop cracks after
many miles of driving. A tire and/or wheel
could fail suddenly, causing a crash. Use only
radial-ply tires with the wheels on your vehicle.
Uniform Tire Quality Grading
Quality grades can be found where applicable on the
tire sidewall between tread shoulder and maximum
section width. For example:
Treadwear 200 Traction AA Temperature A
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration, which grades tires by
treadwear, traction and temperature performance. (This
applies only to vehicles sold in the United States.)
The grades are molded on the sidewalls of most
passenger car tires. The Uniform Tire Quality Grading
system does not apply to deep tread, winter-type
snow tires, space-saver or temporary use spare tires,
tires with nominal rim diameters of 10 to 12 inches
(25 to 30 cm), or to some limited-production tires.
While the tires available on General Motors passenger
cars and light trucks may vary with respect to these
grades, they must also conform to federal safety
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.

Vehicle Identi®cation
Vehicle Identi®cation Number (VIN)
This is the legal identi®er for your vehicle. It appears on
a plate in the front corner of the instrument panel, on
the driver's side. You can see it if you look through the
windshield from outside your vehicle. The VIN also
appears on the Vehicle Certi®cation and Service Parts
labels and the certi®cates of title and registration.
Engine Identi®cation
The 8th character in your VIN is the engine code. This
code will help you identify your engine, speci®cations
and replacement parts.
5-91

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 should blow, see your dealer
for service immediately.
If you ever have a problem on the road and don't have
a spare fuse, you can ªborrowº 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 two fuse blocks, one located
near the engine compartment on the passenger's
side and the other under the rear seat on the driver's
side. If a fuse should blow, have your vehicle serviced
by your dealer immediately.
Underhood Fuse Block
The underhood fuse block is located in the front of the
engine compartment between the windshield washer
¯uid reservoir and the power steering ¯uid reservoir on
the passenger's side of the vehicle. See
Engine
Compartment Overview on page 5-12for more
information on location.
To access the fuses, push in the two tabs located at
each end of the fuse block cover. Then, lift the cover off.
