CAUTION:
You can be injured and your vehicle could be
damaged if you try to do service work on a
vehicle without knowing enough about it.
Be sure you have sufficient knowledge,
experience, the proper replacement parts
and tools before you attempt any vehicle
maintenance task.
Be sure to use the proper nuts, bolts and
other fasteners. ªEnglishº and ªmetricº
fasteners can be easily confused. If you use
the wrong fasteners, parts can later break
or fall off. You could be hurt.
Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the airflow around it. This may cause wind noise
and affect windshield washer performance. Check with
your dealer before adding equipment to the outside of
your vehicle.
Fuel
The 8th digit of your vehicle identification number
(VIN) shows the code letter or number that identifies
your engine. You will find the VIN at the top left of the
instrument panel. See ªVehicle Identification Numberº
in the Index.
Gasoline Octane
If your vehicle has the 3100 V6 engine (VIN Code J)
or 3800 V6 engine (VIN Code K), use regular unleaded
gasoline with a posted octane of 87 or higher. If the
octane is less than 87, you may get a heavy knocking
noise when you drive. If it is bad enough, it can damage
your engine. A little pinging noise when you accelerate
or drive uphill is considered normal. This does not
indicate a problem exists or that a higher
-octane fuel
is necessary.
If your vehicle has the 3800 Supercharged V6 engine
(VIN Code1), use only premium unleaded gasoline with
a posted octane of 91 or higher. In an emergency, you
may be able to use a lower octane
-- as low as 87 -- if
heavy knocking does not occur. Refill your tank with
premium fuel as soon as possible. If you are using
91 octane or higher
-octane fuel and you hear heavy
knocking, your engine needs service.

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 is protected by a circuit breaker in
the instrument panel fuse block. An electrical overload
will cause the lamps to go on and off, or in some cases
to remain off. If this happens, have your headlamp
system checked right away.
Windshield Wipers
The windshield wiper motor is protected by a circuit
breaker and a fuse. If the motor overheats due to heavy
snow, etc., the wiper will stop until the motor cools.
If the overload is caused by some electrical problem,
have it fixed.

6-69 Power Windows and Other Power Options
Circuit breakers in the fuse panel 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.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links in the wiring itself. This
greatly reduces the chance of fires 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. Spare fuses are located in the instrument
panel. See ªUnderhood Fuse Blockº in the Index.Instrument Panel Fuse Block
Some fuses are in a fuse block located inside of the
glove box behind a small bin on the right side. To open,
pull the cover out. The fuse block is inside. On the back
edge of this cover is a fuse puller and a fuse usage chart.
To use the fuse puller, place the wide end of the fuse
puller over the plastic end of the fuse. Squeeze the ends
over the fuse and pull it out.
To reinstall the bin, position the lower end and turn
the top into position. Press on the sides until it snaps
into place.
