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.
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.
The battery is located under the rear seat cushion.
To access the battery, see ªRemoving the Rear Seat
Cushionº in the Index. You don't need to access the
battery to jump start your vehicle. See ªJump Startingº
in the Index.
CAUTION:
A battery that isn't properly vented can let
sulfuric acid fumes into the area under the rear
seat cushion. These fumes can damage your rear
seat safety belt systems. You may not be able to
see this damage, and the safety belts might not
provide the protection needed in a crash. If a
replacement battery is ever needed, it must be
vented in the same manner as the original
battery. Always make sure that the vent hose
is properly reattached before reinstalling the
seat cushion.

6-32
To be sure the vent hose (A) is properly attached, the
vent hose connectors (B) must be securely reattached to
the vent outlets (C) on each side of the battery, and the
vent assembly grommet (D) must be secured to the
floor pan (E).
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.
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.
Contact your dealer to learn how to prepare your vehicle
for longer storage periods.
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's service department.
For the bulb types to be used in the following
procedures, see ªReplacement Bulbsº in the Index.
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
This procedure is for both the driver's and passenger's
side headlamps.
1. Remove the two bolts retaining the headlamp assembly.
2. Slide the headlamp outward until the pins are loose.
3. Remove the headlamp assembly to access the bulbs.

6-34
4. Turn the bulb retainer counterclockwise to remove
the bulb assembly.
5. Pull the bulb straight out from the retainer.
6. Push the new bulb straight into the retainer.
7. Reverse Steps 1 through 4 to reinstall the
bulb assembly.Headlamp Aiming
Your vehicle has a visual optical headlamp aiming
system equipped with horizontal aim indicators.
The aim has been pre
-set at the factory and should
need no further adjustment. This is true even though
your horizontal aim indicators may not fall exactly on
the ª0º (zero) marks on their scales.

6-35
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 your dealer for service.
However, it is possible for you to re
-aim your
headlamps as described in the following procedure.
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.
The vehicle should be properly prepared as follows:

The vehicle should be placed so the headlamps
are 25 ft. (7.6 m) from a light colored wall or
other flat surface.

The vehicle must have all four tires on a perfectly
level surface which is level all the way to the wall or
other flat surface.

The vehicle should be placed so it is perpendicular to
the wall or other flat surface.

The vehicle should not have any snow, ice or mud
attached to it.

The vehicle should be fully assembled and all other
work stopped while headlamp aiming is being done.

The vehicle should be normally loaded with a full
tank of fuel and one person or 160 lbs. (75 kg) on
the driver's seat.

Tires should be properly inflated.
Headlamp aiming is done with the vehicle low beam
lamps. The high beam lamps will be correctly aimed
if the low beam lamps are aimed properly.

6-36
The headlamp aiming devices are under the hood near
the headlamps.
If you believe your headlamps need horizontal
(left/right) adjustment, follow the horizontal aiming
procedure. If you believe your headlamps need only
vertical (up/down) adjustment, follow only the vertical
aiming procedure.
Adjustment screws can be turned with an E8 Torx


socket or T15 Torx screwdriver.Headlamp Horizontal Aiming
Turn the horizontal aiming screw (A) until the
indicator (B) is lined up with zero.
Once the horizontal aim is adjusted, then adjust the
vertical aim.

6-37
Headlamp Vertical Aiming
1. Find the aim dot on the lens of the lamps.
2. Measure the distance from the ground to the aim dot
on each lamp; if left low beam, subtract two inches.
Record this distance.3. At the wall or other flat surface, measure from the
floor to the recorded distance and draw a horizontal
line the width of the vehicle.

6-38
4. Turn on the low beam headlamps and place a piece of
cardboard or equivalent in front of the headlamp not
being aimed. This should allow the beam cut
-off of the
headlamp being aimed to be seen on the flat surface.
NOTICE:
Do not cover a headlamp to improve beam
cut
-off when aiming. Covering a headlamp may
cause excessive heat build
-up which may cause
damage to the headlamp.
5. Turn the vertical aiming screw (C) until the
headlamp beam is aimed to the horizontal tape line.

6-39 Front Turn Signal
Once the headlamp assembly has been removed from
the vehicle, the front turn signal bulbs can be accessed.
1. Reach down into the space provided by the removal
of the headlamp assembly and, while pushing in the
tab on the bulb assembly, turn the assembly
counterclockwise and remove it.
2. Remove the old bulb by pulling it straight out of
the retainer.
3. Install the new bulb and turn the bulb assembly back
into place.
Cornering Lamps
Follow the same procedure as used for replacing the
headlamps. However, to remove the cornering lamp
bulb, press the tab on the bulb assembly while turning
the bulb assembly counterclockwise. Pull the bulb
straight out. Replace the bulb and turn the bulb
assembly back into place.
Trunk-Mounted Back-Up and Taillamps
1. Loosen and remove the seven fasteners that hold the
assembly in place. The assembly for both sides is
one piece. The entire piece must be removed to
replace any bulbs.

6-40
2. Pull out the assembly.3. Push in the tab and turn the bulb socket
counterclockwise to remove it.
4. Remove the bulb by pulling it straight out.
5. Replace the bulb and reverse the steps to install
the new bulb socket.
