Power Lumbar
If the seats have power lumbar, the controls used
to operate this feature are located on the
outboard side of the seats.
To increase lumbar support, press and hold
the front of the control.
To decrease lumbar support, press and hold
the rear of the control.
To raise the height of the lumbar support,
press and hold the top of the control.
To lower the height of the lumbar support,
press and hold the bottom of the control.
Release the control when the lower seatback
reaches the desired level of lumbar support.
Your vehicle may have a memory function which
allows seat settings to be saved and recalled.
SeeMemory Seat, Mirrors, and Pedals on page 13
for more information.
Keep in mind that as your seating position
changes, as it may during long trips, so should the
position of your lumbar support. Adjust the seat
as needed.
11

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.Pull the head restraint
up to raise it. To lower
the head restraint,
press the release
button (A), located on
the top of the seatback,
while you push the
head restraint down.
The front seats may have head restraints that also
tilt forward and rearward.
To tilt the head restraint, grasp the top of the
restraint while pressing the button (B), located on
the right hand side of the head restraint, and
move it forward or rearward until the desired
locking position is reached. Try to move the head
restraint after the button is released to make
sure that it is locked in place.
The second row seats may have head restraints
that can be adjusted up and down, but they do
not tilt.

4. Push the latch plate into the buckle until
it clicks.
Pull up on the latch plate to make sure it is
secure. If the belt is not long enough,
seeSafety Belt Extender on page 60.
Make sure the release button on the buckle is
positioned so you would be able to unbuckle
the safety belt quickly if you ever had to.
5. Move the shoulder belt height adjuster 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 on page 51.
6. To make the lap part tight, pull up on the
shoulder belt.
45

To unlatch the belt, just push the button on the
buckle. The belt should go back out of the way.
Before you close the 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 Adjustment
Before you begin to drive, move the shoulder belt
adjuster to the height that is right for you.
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.

{CAUTION:
Children who are up against, or very close
to, any airbag when it inates can be
seriously injured or killed. Airbags plus
lap-shoulder belts offer protection for
adults and older children, but not for
young children and infants.
CAUTION: (Continued)
CAUTION: (Continued)
Neither the vehicle’s safety belt system
nor its airbag system is designed for
them. Young children and infants need the
protection that a child restraint system
can provide.
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.
66

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:
Newborn infants need complete support,
including support for the head and neck.
This is necessary because a newborn
infant’s neck is weak and its head weighs
so much compared with the rest of its
body. In a crash, an infant in a rear-facing
seat 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 always
should be secured in appropriate infant
restraints.
{CAUTION:
The body structure of a young child is
quite unlike that of an adult or older child,
for whom the safety belts are designed. A
young child’s hip bones are still so small
that the vehicle’s regular safety belt may
not remain low on the hip bones, as it
should. Instead, it may settle up around
the child’s abdomen. In a crash, the belt
would apply force on a body area that is
unprotected by any bony structure. This
alone could cause serious or fatal injuries.
Young children always should be secured
in appropriate child restraints.

Adding Equipment to Your
Airbag-Equipped Vehicle
Q:Is there anything I might add to the front
or sides of the vehicle that could keep the
airbags from working properly?
A:Yes. If you add things that change your
vehicle’s frame, bumper system, front end or
side sheet metal or height, they may keep the
airbag system from working properly. Also, the
airbag system may not work properly if you
relocate any of the airbag sensors. If you have
any questions about this, you should contact
Customer Assistance before you modify your
vehicle. The phone numbers and addresses for
Customer Assistance are in Step Two of the
Customer Satisfaction Procedure in this
manual. SeeCustomer Satisfaction Procedure
on page 572.
Q:Because I have a disability, I have to get
my vehicle modied. How can I nd out
whether this will affect my airbag system?
A:Changing or moving any parts of the front
seats, safety belts, the airbag sensing and
diagnostic module (located under the driver’s
seat), rollover sensor module (located under
the center console), instrument panel, steering
wheel, ceiling headliner, ceiling and pillar
garnish trim, roof-mounted rollover airbag
modules or airbag wiring can affect the
operation of the airbag system. If you have
questions, call Customer Assistance. The
phone numbers and addresses for Customer
Assistance are in Step Two of the Customer
Satisfaction Procedure in this manual. See
Customer Satisfaction Procedure on page 572.

{CAUTION:
Shifting a four-wheel-drive vehicle’s
transfer case into NEUTRAL can cause
your vehicle to roll even if the
transmission is in PARK (P). You or
others could be injured. Make sure the
parking brake is rmly set before you shift
the transfer case to NEUTRAL.
6. Shift the transfer case to NEUTRAL. See
Four-Wheel Drive on page 146for the
proper procedure to select the NEUTRAL
position for your vehicle.
7. Release the parking brake only after the
vehicle being towed is rmly attached to
the towing vehicle.
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 self-equalizing 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 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 rmly.
{CAUTION:
The brake wear warning sound means that
soon your 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 may cause a
brake squeal when the brakes are rst 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 tighten
wheel nuts in the proper sequence to GM torque
specications.
Brake linings should always be replaced as
complete axle sets.
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 make a brake stop, your disc
brakes adjust for wear.
