Shoulder Belt Height Adjuster
Before you begin to drive, move the shoulder belt
adjuster to the height that is right for you.To move it down, push down on the button and move
the height adjuster to the desired position. You can move
the adjuster up just by pushing up on the shoulder belt
guide. After you move the adjuster to where you want it,
try to move it down without pushing the button down to
make sure it has locked into position.
Adjust the height so that the shoulder portion of the belt
is centered on your shoulder. The belt should be away
from your face and neck, but not falling off
your shoulder.

This child restraint system conforms to all applicable
Federal Motor Vehicle Safety Standards.
Each child restraint is designed for use only by children
who weigh between 22 and 40 pounds (10 and 18 kg)
and whose height is between 33.5 and 40 inches
(850 and 1 016 mm) and who are capable of sitting
upright alone.
The child should also be at least one year old. It is
important to use a rear
-facing infant restraint until the
child is about a year old. A rear
-facing restraint gives
the infant's head, neck and body the support they would
need in a crash. See ªChild Restraintsº later in this
section for more information.
Q:What if the top of my child's shoulders is above
the shoulder belt slots for the five
-point child
restraint harness system?
A:A child whose shoulders are above the shoulder
belt slots for the five
-point child restraint harness
system shouldn't use this child restraint. Instead,
the child should sit on the vehicle's regular seat
cushion and use the vehicle's adult safety belts.
CAUTION:
BEFORE YOU USE THIS CHILD RESTRAINT,
BE SURE THE TOP OF THE CHILD'S
SHOULDERS IS BELOW THE SLOTS THAT
THE HARNESS GOES THROUGH. A CHILD
WHOSE SHOULDERS ARE ABOVE THOSE
SLOTS COULD BE INJURED DURING A
SUDDEN STOP OR CRASH. IF THE TOP OF
THE CHILD'S SHOULDERS IS ABOVE THE
SLOTS, DON'T USE THIS CHILD
RESTRAINT WHILE THE VEHICLE IS
IN MOTION.

A forward-facing child restraint (C-E) positions a
child upright to face forward in the vehicle. These
forward
-facing restraints are designed to help
protect children who are from 20 to 40 lbs.
(9 to 18 kg) and about 26 to 40 inches
(66 to 102 cm) in height, or up to around four years
of age. One type, a convertible restraint, is
designed to be used either as a rear
-facing infant
seat or a forward
-facing child seat.

6-30 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.
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 an ACDelco Freedom

battery. When it's time for a new battery, we recommend
an ACDelco Freedom battery. Get one that has the
replacement number shown on the original battery's label.
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.

6-45 Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
carefully at the factory to give you the longest tire life
and best overall performance.
Scheduled wheel alignment and wheel balancing are not
needed. However, if you notice unusual tire wear or
your vehicle pulling one way or the other, the alignment
may need to be reset. If you notice your vehicle
vibrating when driving on a smooth road, your wheels
may need to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted
or corroded. If wheel nuts keep coming loose, the wheel,
wheel bolts and wheel nuts should be replaced. If the
wheel leaks air, replace it (except some aluminum
wheels, which can sometimes be repaired). See your
dealer if any of these conditions exist.
Your dealer will know the kind of wheel you need.
Each new wheel should have the same load
-carrying
capacity, diameter, width, offset and be mounted the
same way as the one it replaces.
If you need to replace any of your wheels, wheel bolts
or wheel nuts, replace them only with new GM original
equipment parts. This way, you will be sure to have the
right wheel, wheel bolts and wheel nuts for your vehicle.
CAUTION:
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 ªChanging a Flat Tireº in the Index for
more information.
