Head Restraint
Adjustment
Do not drive until the head restraints
for all occupants are installed and

position, change the seatback
recline angle as little as necessary
while keeping the seat and the
head restraint height in the proper
position.

Safety Belt
Refer to the following sections for
important information on how to use
safety belts properly.
.Safety Belts on page 3‑14.

Sensing System for
Passenger Airbag
The passenger sensing system,
if equipped, turns off the right
front passenger frontal airbag
under certain conditions. The driver
airbags, seat‐mounted side impact
airbags and roof‐rail airbags are
not affected by this.
If the vehicle has one of the
indicators pictured in the following
illustrations, then the vehicle has
a passenger sensing system for the
right front passenger position unless
there is an airbag off switch located
in the glove box.
If there is an airbag off switch, the
vehicle does not have a passenger
sensing system. See Airbag On-Off
Switch
on page 3‑39for more
information.

Head Restraints
The front seats have adjustable
head restraints in the outboard
seating positions.
{WARNING
With head restraints that are not
installed and adjusted properly,
there is a greater chance that
occupants will suffer a neck/
spinal injury in a crash. Do not
drive until the head restraints for
all occupants are installed and
adjusted properly.
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 button, located on the
top of the seatback, and push the
restraint down.
Push down on the head restraint
after the button is released to make
sure that it is locked in place.
The head restraints are not
designed to be removed.
The rear seat has headrests that
can be adjusted up and down.

If the belt stops before it reaches
the buckle, when using the
lap-shoulder belt in a rear center
seating position of a crew-cab,
tilt the latch plate and keep
pulling the safety belt until
it can be buckled.3. Push the latch plate into thebuckle until it clicks.
Pull up on the latch plate to
make sure it is secure. If the belt
is not long enough, see Safety
Belt Extender on page 3‑29.
If the latch plate will not go fully
into the buckle, check if the
correct buckle is being used.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary. 4. If equipped with a shoulder belt
height adjuster, move it to the
height that is right for you. See
“Shoulder Belt Height Adjuster”
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
return to its stowed position.
Before a door is closed, be sure the
safety belt is out of the way. If a
door is slammed against a safety
belt, damage can occur to both the
safety belt and the vehicle.
Shoulder Belt Height Adjuster
The vehicle has a shoulder belt
height adjuster for the driver and
right front passenger.
Adjust the height so the shoulder
portion of the belt is on the shoulder
and not falling off of it. The belt
should be close to, but not
contacting, the neck. Improper
shoulder belt height adjustment
could reduce the effectiveness of
the safety belt in a crash. SeeHow
to Wear Safety Belts Properly
on
page 3‑17.
Regular and Crew Cab
To move the adjuster down for the
regular and crew cabs, squeeze
the buttons (A) on the sides of the
height adjuster and move the height
adjuster to the desired position.

Extended Cab
On the extended cab, push down
on the release button (A) 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
for the regular and crew cabs,
or without pushing the release
button for extended cabs, to make
sure it has locked into position.
Safety Belt Pretensioners
This vehicle has safety belt
pretensioners for front outboard
occupants. Although the safety
belt pretensioners cannot be seen,
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 the
pretensioners activate in a crash,
they will need to be replaced,
and probably other new parts
for the vehicle's safety belt system.
See
Replacing Safety Belt System
Parts After a Crash on page 3‑30.
Rear Safety Belt Comfort
Guides
This vehicle may have rear shoulder
belt comfort guides. If not, they
are available through your dealer.
The guides may provide added
safety belt comfort for older children
who have outgrown booster seats
and for some adults. When installed
and properly adjusted, the comfort
guide positions the belt away from
the neck and head.

Servicing the
Airbag-Equipped Vehicle
Airbags affect how the vehicle
should be serviced. There are
parts of the airbag system in
several places around the vehicle.
Your dealer and the service manual
have information about servicing
the vehicle and the airbag system.
To purchase a service manual,
seeService Publications Ordering
Information on page 13‑14.
{WARNING
For up to 10 seconds after the
ignition is turned off and the
battery is disconnected, an airbag
can still inflate during improper
service. You can be injured if you
are close to an airbag when it
inflates. Avoid yellow connectors.
They are probably part of the
airbag system. Be sure to follow
(Continued)
WARNING (Continued)
proper service procedures, and
make sure the person performing
work for you is qualified to do so.
Adding Equipment to the
Airbag-Equipped Vehicle
Q: Is there anything I might addto 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,
or airbag wiring can affect the
operation of the airbag system.
In addition, the vehicle may have
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 different
vehicle. Any object, such as
an aftermarket seat heater or
a comfort enhancing pad or
device, installed under or on top
of the seat fabric, could also
interfere with the operation of
the passenger sensing system.
