Vehicle Storage
If you’re not going to drive your vehicle for 25 days or
more, remove the black, negative (-) cable from the
battery. This will help keep your battery
from
running down.
/I CAUTION:
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt
if you
aren’t careful. See “Jump Starting” in the Index
for tips on working around
a battery without
getting hurt.
Halogen Bulbs
Contact your dealer to learn how to prepare your vehicle
for longer storage periods.
Also, for your audio system, see “Theft-Deterrent
Feature” in the Index.
Bulb Replacement
In this section, you’ll find directions for changing the
bulbs on your vehicle. See “Replacement Bulbs” in the
Index to find the type
of bulb you should use. 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.

A CAUTION:
Used Replacement Wheels
Using the wrong replacement wheels, wheel
bolts
or wheel nuts 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, wheel
bolts and wheel nuts 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 “Changing a Flat Tire” in the Index for
more information.
‘ A 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.
Tire Chains
NOTICE:
If your vehicle has P225160R16 size tires, don’t
use tire chains. They can damage your vehicle
because there’s not enough clearance.
NOTICE: (Continued)

Electrical System
kdd-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 “Servicing
Your
Air Bag-Equipped Vehicle” in the Index.
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 “Underhood Electrical Center” in the Index.
Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the underhood electrical center. 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.
