6. To tighten the belt, push down on the child restraint,
pull the shoulder portion of the belt to tighten the lap
portion of the belt and feed the shoulder belt back
into the retractor. When installing a forward-facing
child restraint, it may be helpful to use your knee
to push down on the child restraint as you tighten
the belt.
7. Push and pull the child restraint in different
directions to be sure it is secure.
To remove the child restraint, unbuckle the vehicle
safety belt and let it return to the stowed position.If you turned the airbag off with the switch, turn on the
right front passenger airbag when you remove the child
restraint from the vehicle unless the person who will be
sitting there is a member of a passenger airbag risk
group. SeeAirbag Off Switch on page 1-76for more
information, including important safety information.
Airbag System
The vehicle has the following airbags:
A frontal airbag for the driver.
A frontal airbag for the right front passenger.
A roof-rail airbag for the driver and the passenger
seated directly behind the driver.
A roof-rail airbag for the right front passenger and
the passenger seated directly behind the right
front passenger.
The vehicle may have the following airbags:
If your vehicle has a third row seat, it will have third
row roof-rail airbags.
All of the airbags in your vehicle will have the word
AIRBAG embossed in the trim or on an attached label
near the deployment opening.
For frontal airbags, the word AIRBAG will appear on the
middle part of the steering wheel for the driver and
on the instrument panel for the right front passenger.
With roof-rail airbags, the word AIRBAG will appear
along the headliner or trim.
1-67

{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. 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.
Always secure children properly in your vehicle.
To read how, seeOlder Children on page 1-40or
Infants and Young Children on page 1-43.
There is an airbag
readiness light on the
instrument panel cluster,
which shows the airbag
symbol.
The system checks the airbag electrical system for
malfunctions. The light tells you if there is an electrical
problem. SeeAirbag Readiness Light on page 3-32for
more information.
Where Are the Airbags?
The driver’s frontal airbag is in the middle of the
steering wheel.
1-69

If your vehicle has roof-rail airbags and a third row
passenger seat, the airbags are located in the ceiling
above the rear windows for the outboard passenger
positions in the third row.
{CAUTION:
If something is between an occupant and an
airbag, the airbag might not inate properly or it
might force the object into that person causing
severe injury or even death. The path of an
inating airbag must be kept clear. Do not put
anything between an occupant and an airbag, and
do not attach or put anything on the steering
wheel hub or on or near any other airbag
covering.
Never secure anything to the roof of a vehicle with
roof-rail airbags by routing a rope or tie down
through any door or window opening. If you do,
the path of an inating roof-rail airbag will be
blocked. Driver Side shown, Passenger Side similar
1-71

Your vehicle has roof-rail airbags. SeeAirbag System
on page 1-67. Roof-rail airbags are intended to inate in
moderate to severe side crashes. In addition, these
roof-rail airbags are intended to inate during a rollover.
Roof-rail airbags will inate if the crash severity is
above the system’s designed threshold level. The
threshold level can vary with specic vehicle design.
Roof-rail airbags are not intended to inate in frontal
impacts, near-frontal impacts, or rear impacts. Both
roof-rail airbags will deploy when either side of
the vehicle is struck, or if the sensing system predicts
that the vehicle is about to roll over.
In any particular crash, no one can say whether an
airbag should have inated simply because of the
damage to a vehicle or because of what the repair costs
were. For frontal airbags, ination is determined by
what the vehicle hits, the angle of the impact, and how
quickly the vehicle slows down. For roof-rail airbags,
deployment is determined by the location and severity of
the side impact. In a rollover event, roof-rail airbag
deployment is determined by the direction of the roll.What Makes an Airbag Inate?
In a deployment event, the sensing system sends an
electrical signal triggering a release of gas from the
inator. Gas from the inator lls the airbag causing the
bag to break out of the cover and deploy. The inator, the
airbag, and related hardware are all part of the airbag
module.
Frontal airbag modules are located inside the steering
wheel and instrument panel. For vehicles with
roof-rail airbags, there are airbag modules in the ceiling
of the vehicle, near the side windows that have
occupant seating positions.
1-73

How Does an Airbag Restrain?
In moderate to severe frontal or near frontal collisions,
even belted occupants can contact the steering wheel
or the instrument panel. In moderate to severe side
collisions, even belted occupants can contact the inside
of the vehicle.
Airbags supplement the protection provided by safety
belts. Frontal airbags distribute the force of the impact
more evenly over the occupant’s upper body, stopping
the occupant more gradually. Roof-rail airbags distribute
the force of the impact more evenly over the occupant’s
upper body.
Rollover capable roof-rail airbags are designed to help
contain the head and chest of occupants in the
outboard seating positions in the rst, second, and third
rows, if equipped with a third row seat. The rollover
capable roof-rail airbags are designed to help reduce the
risk of full or partial ejection in rollover events, although
no system can prevent all such ejections.
But airbags would not help in many types of collisions,
primarily because the occupant’s motion is not
toward those airbags. SeeWhen Should an Airbag
Inflate? on page 1-72for more information.
Airbags should never be regarded as anything more
than a supplement to safety belts.
What Will You See After an Airbag
Inates?
After the frontal airbags inate, they quickly deate,
so quickly that some people may not even realize
an airbag inated. Roof-rail airbags may still be at
least partially inated for some time after they deploy.
Some components of the airbag module may be hot for
several minutes. For location of the airbag modules, see
What Makes an Airbag Inflate? on page 1-73.
The parts of the airbag that come into contact with you
may be warm, but not too hot to touch. There may
be some smoke and dust coming from the vents in the
deated airbags. Airbag ination does not prevent
the driver from seeing out of the windshield or being
able to steer the vehicle, nor does it prevent people from
leaving the vehicle.

Servicing Your 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/retailer 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 7-15.
{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.
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 7-2.
If your vehicle has rollover roof-rail airbags, seeDifferent
Size Tires and Wheels on page 5-74for additional
important information.

Midgate Window
K
(Midgate Window):On vehicles with a Midgate,
the switch to operate the window is located on the
instrument panel to the left of the steering wheel.
SeeInstrument Panel Overview on page 3-4.
ª:Press to express-down the window.
y:Press to express-up the window.
Press the top or bottom of the switch a second time to
stop the window.
The window switch will operate while the ignition is in
ON/RUN or ACC/ACCESSORY, or while Retained
Accessory Power (RAP) is active. SeeRetained
Accessory Power (RAP) on page 2-29.
The window can also be operated using the global
window buttons. See “Global Window Feature”
previously.
{CAUTION:
If express override is activated, the midgate
window will not reverse automatically. You or
others could be injured and the window could be
damaged. Before you use express override, make
sure that all people and obstructions are clear of
the midgate window path.
Midgate Window Express Override Mode
If an obstruction or weather condition such as severe
icing stops the window as it is moving upward, the
window will automatically reverse to a partially open
position. The window will return to normal operation
once the obstruction or condition is removed.
The window auto-reversal function can be overridden
in the express override mode. To override, the window
must be operated manually by pressing and holding the
Midgate window switch or the global window button.
This must be done within two seconds after the Midgate
window has stopped at a partially open position.
The express override mode only works immediately
following a window auto-reversal. Window express
functions will not work while in this mode.
2-22

Ignition Positions
The ignition switch has
four different positions.
To shift out of P (Park), the ignition must be in ON/RUN
or ACC/ACCESSORY and the regular brake pedal
must be applied.A (LOCK/OFF):This position locks the ignition. It also
locks the transmission on automatic transmission
vehicles. The key can be removed in LOCK/OFF.
On vehicles with an automatic transmission, the shift
lever must be in P (Park) to turn the ignition switch
to LOCK/OFF.
The steering can bind with the wheels turned off center.
If this happens, move the steering wheel from right
to left while turning the key to ACC/ACCESSORY.
If this doesn’t work, then the vehicle needs service.
Notice:Using a tool to force the key to turn in
the ignition could cause damage to the switch or
break the key. Use the correct key, make sure it is
all the way in, and turn it only with your hand.
If the key cannot be turned by hand, see your
dealer/retailer.
B (ACC/ACCESSORY):This position lets things like
the radio and the windshield wipers operate while
the engine is off. Use this position if the vehicle must
be pushed or towed.
2-28

Driver Shift Control (DSC)
The vehicle has Driver Shift Control (DSC). DSC
controls the transmission and vehicle speed while driving
down hill or towing a trailer by allowing you to select
a desired range of gears.
To use this feature:
1. Move the shift lever to the M (Manual Mode).
This will force a downshift from the current gear,
for gears 3 through 6.
2. Press the (+) plus or (−) minus button on the left
side of the steering wheel, to select the desired
range of gears for current driving conditions.When in the M (Manual Mode) a number will display
next to the M, indicating the maximum available gear.
The DIC display will show the message MANUAL SHIFT
on the rst line and the maximum available gear will be
displayed on the second line. SeeDriver Information
Center (DIC) on page 3-46andDIC Operation and
Displays (Using DIC Buttons) on page 3-47orDIC
Operation and Displays (Using Trip Odometer Reset
Stem) on page 3-52for more information. The number
displayed in the DIC is the highest gear available.
The transmission will be limited to the gear selected and
lower gears. Shifting will occur normally while driving,
however the cluster will continue to display the maximum
available gear. Higher gears will not be available unless
the selection is changed to include higher gears using
the (+) plus button.
Grade Braking is not available when the Driver Shift
Control is active. SeeTow/Haul Mode on page 2-36and
Towing a Trailer on page 4-55for more information.
While using the DSC, cruise control and the tow/haul
mode can be used.
