Power Reclining Seatbacks
If the seats have power reclining seatbacks, the control
used to recline them is located on the outboard side
of the seat behind the power seat control.
To recline the seatback, tilt the top of the control
rearward.
To bring the seatback forward, tilt the top of the
control forward.
Do not have a seatback reclined if your vehicle is
moving.
Head Restraints
Adjust the head restraint so that the top of the restraint
is at the same height as the top of the occupant’s
head. This position reduces the chance of a neck injury
in a crash.

4. If equipped with a shoulder belt height adjuster,
move it to the height that is right for you. Improper
shoulder belt height adjustment could reduce
the effectiveness of the safety belt in a crash.
See “Shoulder Belt Height Adjustment” later
in this section.
5. To make the lap part tight, pull up on the
shoulder belt.
It may be necessary to pull stitching on the safety
belt through the latch plate to fully tighten the
lap belt on smaller occupants.To unlatch the belt, push the button on the buckle.
The belt should go back out of the way.
Before you close a door, be sure the belt is out of
the way. If you slam the door on it, you can damage
both the belt and your vehicle.

Shoulder Belt Height Adjuster
Your vehicle has a shoulder belt height adjuster for
the driver and right front passenger 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.
Improper shoulder belt height adjustment could reduce
the effectiveness of the safety belt in a crash.
To move it down, squeeze
the buttons (A) on the sides
of the height adjuster 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 squeezing the buttons to
make sure it has locked into position.
Safety Belt Pretensioners
Your vehicle has safety belt pretensioners for front
outboard occupants. Although you cannot see them,
they are part of the safety belt assembly. They can
help tighten the safety belts during the early stages of a
moderate to severe frontal, near frontal, or rear crash
if the threshold conditions for pretensioner activation
are met. And, if your vehicle has side impact airbags,
safety belt pretensioners can help tighten the safety
belts in a side crash or a rollover event.
Pretensioners work only once. If they activate in a
crash, you will need to get new ones, and probably other
new parts for your safety belt system. SeeReplacing
Restraint System Parts After a Crash on page 1-93.
Rear Safety Belt Comfort Guides
Rear shoulder belt comfort guides may provide added
safety belt comfort for older children who have outgrown
booster seats and for some adults. When installed on
a shoulder belt, the comfort guide positions the belt
away from the neck and head.
1-44

The manufacturer’s instructions that come with the
booster seat, state the weight and height limitations for
that booster. Use a booster seat with a lap-shoulder
belt until the child passes the below t test:
Sit all the way back on the seat. Do the knees bend
at the seat edge? If yes, continue. If no, return to
the booster seat.
Buckle the lap-shoulder belt. Does the shoulder belt
rest on the shoulder? If yes, continue. If no, try using
the rear safety belt comfort guide. See “Rear Safety
Belt Comfort Guides” underLap-Shoulder Belt on
page 1-42for more information. If the shoulder belt
still does not rest on the shoulder, then return to the
booster seat.
Does the lap belt t low and snug on the hips,
touching the thighs? If yes, continue. If no, return
to the booster seat.
Can proper safety belt t be maintained for length of
trip? If yes, continue. If no, return to the booster seat.
If you have the choice, a child should sit in a position
with a lap-shoulder belt and get the additional restraint
a shoulder belt can provide.
Q:What is the proper way to wear safety belts?
A:An older child should wear a lap-shoulder belt
and get the additional restraint a shoulder belt
can provide. The shoulder belt should not cross
the face or neck. The lap belt should t snugly
below the hips, just touching the top of the thighs.
This applies belt force to the child’s pelvic bones
in a crash. It should never be worn over the
abdomen, which could cause severe or even fatal
internal injuries in a crash.
Also see “Rear Safety Belt Comfort Guides” under
Lap-Shoulder Belt on page 1-42.
According to accident statistics, children and infants
are safer when properly restrained in the rear seating
positions than in the front seating positions.
1-51

Q:What are the different types of add-on child
restraints?
A:Add-on child restraints, which are purchased by the
vehicle’s owner, are available in four basic types.
Selection of a particular restraint should take
into consideration not only the child’s weight, height,
and age but also whether or not the restraint will
be compatible with the motor vehicle in which it
will be used.
For most basic types of child restraints, there are
many different models available. When purchasing
a child restraint, be sure it is designed to be
used in a motor vehicle. If it is, the restraint will
have a label saying that it meets federal motor
vehicle safety standards.
The restraint manufacturer’s instructions that come
with the restraint state the weight and height
limitations for a particular child restraint. In addition,
there are many kinds of restraints available for
children with special needs.
{CAUTION:
To reduce the risk of neck and head injury
during a crash, infants need complete support.
This is because an infant’s neck is not fully
developed and its head weighs so much
compared with the rest of its body. In a crash,
an infant in a rear-facing child restraint settles
into the restraint, so the crash forces can be
distributed across the strongest part of an
infant’s body, the back and shoulders. Infants
should always be secured in rear-facing child
restraints.

Servicing Your Airbag-Equipped
Vehicle
Airbags affect how your vehicle should be serviced.
There are parts of the airbag system in several places
around your vehicle. Your dealer/retailer and the
service manual have information about servicing your
vehicle and the airbag system. To purchase a service
manual, seeService Publications Ordering Information
on page 7-16.
{CAUTION:
For up to 10 seconds after the ignition is
turned off and the battery is disconnected,
an airbag can still inate during improper
service. You can be injured if you are close
to an airbag when it inates. Avoid yellow
connectors. They are probably part of the
airbag system. Be sure to follow proper
service procedures, and make sure the person
performing work for you is qualied to do so.
Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to or change
about the vehicle that could keep the airbags
from working properly?
A:Yes. If you add things that change your vehicle’s
frame, bumper system, height, front end or side
sheet metal, they may keep the airbag system from
working properly. Changing or moving any parts of
the front seats, safety belts, the airbag sensing and
diagnostic module, steering wheel, instrument panel,
roof-rail airbag modules, ceiling headliner or pillar
garnish trim, overhead console, front sensors, side
impact sensors, rollover sensor module, or airbag
wiring can affect the operation of the airbag system.
In addition, your vehicle has a passenger sensing
system for the right front passenger’s position, which
includes sensors that are part of the passenger’s
seat. The passenger sensing system may not
operate properly if the original seat trim is replaced
with non-GM covers, upholstery or trim, or with
GM covers, upholstery or trim designed for a

Dolly Towing
Two-Wheel-Drive Vehicles
Notice:If you tow a two-wheel-drive vehicle with
the rear wheels on the ground, the transmission
could be damaged. The repairs would not be
covered by your warranty. Never tow your vehicle
with the rear wheels on the ground.
Two-wheel-drive vehicles should not be towed with the
rear wheels on the ground. Two-wheel-drive
transmissions have no provisions for internal lubrication
while being towed.
Two-wheel-drive vehicles can be towed on a dolly with
the front wheels on the ground provided that the
wheels are straight.
Four-Wheel-Drive Vehicles
Four-wheel-drive vehicles are not designed to be dolly
towed. If you need to tow your vehicle, see “Dinghy
Towing” earlier in this section.
Level Control
Automatic Level Control
The automatic level control rear suspension is available
on two-wheel drive and four-wheel drive light-duty
vehicles and comes as a part of the Autoride
®
suspension, if equipped.
This type of level control is fully automatic and will provide
a better leveled riding position as well as better handling
under a variety of passenger and loading conditions. An
air compressor connected to the rear shocks will raise or
lower the rear of the vehicle to maintain proper vehicle
height. The system is activated when the ignition key is
turned to RUN and will automatically adjust vehicle height
thereafter. The system may exhaust (lower vehicle
height) for up to ten minutes after the ignition key has
been turned off. You may hear the air compressor
operating when the height is being adjusted.
If a weight-distributing hitch is being used, it is
recommended to allow the shocks to inate, thereby
leveling the vehicle prior to adjusting the hitch.

Brake Wear
Your vehicle has 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 can come and go or be heard
all the time your vehicle is moving, except when you
are pushing on the brake pedal rmly.
{CAUTION:
The brake wear warning sound means that
soon the brakes will not 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 can cause a brake
squeal when the brakes are rst applied or lightly applied.
This does not mean something is wrong with the brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly tighten wheel nuts in
the proper sequence to torque specications in
Capacities and Specifications on page 5-126.
Brake linings should always be replaced as complete
axle sets.Brake Pedal Travel
See your dealer/retailer 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 that brake service
might be required.
Brake Adjustment
Every time you make a brake stop, the disc brakes
adjust for wear.
5-46

To adjust the vertical aim:
1. Open the hood. SeeHood Release on page 5-14
for more information.
2. Locate the aim dot on the lens of the low-beam
headlamp.
3. Record the distance from the ground to the aim dot
on the low-beam headlamp.4. At a wall measure from the ground upward (A) to
the recorded distance from Step 3 and mark it.
5. Draw or tape a horizontal line (B) on the wall or at
surface the width of the vehicle at the height of the
mark in Step 4.
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.
6. Turn on the low-beam headlamps and place a
piece of cardboard or equivalent in front of the
headlamp not being adjusted. This allows only the
beam of light from the headlamp being adjusted
to be seen on the at surface.
