6-32 Brake Wear
Your vehicle has four-wheel disc brakes.
Disc brake pads have built
-in wear indicators that make a
high
-pitched warning sound when the brake pads are worn
and new pads are needed. The sound may come and go or
be heard all the time your vehicle is moving (except when
you are pushing on the brake pedal firmly).
CAUTION:
The brake wear warning sound means that soon
your brakes won't work well. That could lead to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong with
your brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly torque wheel nuts in the
proper sequence to GM specifications.
Brake linings should always be replaced as complete
axle sets.
See ªBrake System Inspectionº in the
Maintenance Schedule booklet under Part C ªPeriodic
Maintenance Inspections.º
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in pedal
travel. This could be a sign of brake trouble.
Brake Adjustment
Every time you apply the brakes, with or without the
vehicle moving, your brakes adjust for wear.

6-33 Replacing Brake System Parts
The braking system on a vehicle is complex. Its many
parts have to be of top quality and work well together if
the vehicle is to have really good braking. Your vehicle
was designed and tested with top
-quality GM brake
parts. When you replace parts of your braking
system
-- for example, when your brake linings wear
down and you have to have new ones put in
-- be sure
you get new approved GM replacement parts. If you
don't, your brakes may no longer work properly. For
example, if someone puts in brake linings that are wrong
for your vehicle, the balance between your front and
rear brakes can change
-- for the worse. The braking
performance you've come to expect can change in many
other ways if someone puts in the wrong replacement
brake parts.
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.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.

6-34
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.

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
1. To access the
headlamps, remove all
of the push
-pins that
hold the filler panel
cover in place.
Do this by pressing the center of each pin down, then
remove the pin by pulling up on the outer circle. Then
set the cover aside.

dust cover and set aside.
6. Turn the headlamp
housing socket
counterclockwise to
unlock the socket from
the lamp housing.

To reinstall the filler panel:
1. Place the filler panel in the correct location.
2. Reset each push
-pin by holding each by the outer
circle while pushing up on the pin assembly from
below. The center portion of the push
-pin should
now be above the outer circle.
3. After placing each push
-pin into the opening, press
down on the outer circle until it is seated against the
surface of the filler panel.
4. Lock each push
-pin in place by pressing the center
of each down until they are level with the outer
circles. Use care not to press down so far that the
push
-pin releases again.Headlamp AimingYour 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.
Page 338 of 385

6-39
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.
Allow the headlamps to warm up for one to
two minutes before beginning.
Tires should be properly inflated.
Start the vehicle to level the suspension.
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.
The headlamp aiming devices are under the hood near
the headlamps.

6-40
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.

6-41
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.
