Battery
Your new vehicle comes with a maintenance free
ACDelco
battery. When it's time for a new battery, get
one that has the replacement number shown on the
original battery's label. We recommend an ACDelco
battery. See ªEngine Compartment Overviewº in the
Index for battery location.
WARNING: Battery posts, terminals and related
accessories contain lead and lead compounds, chemicals
known to the State of California to cause cancer and
reproductive harm. Wash hands after handling.
CAUTION:
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
aren't careful. See ªJump Startingº in the Index
for tips on working around a battery without
getting hurt.
After a power loss, such as disconnecting the battery or
removing the maxi fuses in the power distribution fuse
block, the following steps must be performed to
calibrate the electronic throttle control. If this is not
done, the engine will not run properly.
1. Turn the ignition key to the RUN position. Do not
start the engine.
2. Leave the ignition in the RUN position for at least
three minutes so that the electronic throttle control
will cycle and re
-learn its home position.
3. Turn the ignition to OFF.
4. Start and run the engine for at least 30 seconds.
Also, for your audio system, see ªTheft
-Deterrent
Featureº in the Index.
Bulb Replacement
For any bulb changing procedure not listed in this
section, contact your dealer service department.
For bulb types, see ªReplacement Bulbsº in the Index.

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.

6-57 Power Distribution Fuse Block
This fuse block is attached to the engine compartment
relay center located on top of the battery. Simply lift the
lid to open. If you have any questions about the power
distribution fuse block, consult your dealer.
Please note that if a power loss has occurred, such as
disconnecting the battery or removing the Maxi Fuses in
the power distribution fuse block, there are steps that
must be followed to calibrate the electronic throttle
control (ETC). If these steps are not done, the engine
will not run properly. For information regarding these
steps, see ªBatteryº earlier in this section.
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 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.
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.
There are two fuse blocks in your vehicle: the
instrument panel fuse block and the engine
compartment relay center.

Instrument Panel Fuse Block (Driver's Side)
The fuse block is located below the steering wheel on
