•If your liftgate is power closing and you
put the vehicle in gear, the liftgate will
continue to power close. However, ve-
hicle movement may result in a detection
of an obstruction.
WARNING!
•Driving with the liftgate open can allow
poisonous exhaust gases into your vehicle.
You and your passengers could be injured
by these fumes. Keep the liftgate closed
when you are operating the vehicle.
• If you are required to drive with the liftgate
open, make sure that all windows are
closed, and the climate control blower
switch is set at high speed. Do not use the
recirculation mode.
Gas props support the liftgate in the open
position. However, because the gas pressure
drops with temperature, it may be necessary to
assist the props when opening the liftgate in
cold weather.
OCCUPANT RESTRAINTSSome of the most important safety features in
your vehicle are the restraint systems:
• Three-point lap and shoulder belts for the
driver and all passengers
• Advanced Front Air Bags for driver and front
passenger
• Supplemental Active Head Restraints (AHR)
located on top of the front seats (integrated
into the head restraint)
• Supplemental Driver Side Knee Air Bag
• Supplemental Side Air Bag Inflatable Cur-
tains (SABIC) for the driver and passengers
seated next to a window
• Supplemental Seat-Mounted Side Air Bags
(SAB)
• An energy-absorbing steering column and
steering wheel
• Knee bolsters/blockers for front seat occu-
pant •
Front seat belts incorporate pretensioners
that may enhance occupant protection by
managing occupant energy during an im-
pact event
• All seat belt systems (except the driver’s and
front passenger) include Automatic Locking
Retractors (ALRs), which lock the seat belt
webbing into position by extending the belt
all the way out and then adjusting the belt to
the desired length to restrain a child seat or
secure a large item in a seat — if equipped
If you will be carrying children too small for
adult-sized seat belts, the seat belts or the
ISOFIX feature also can be used to hold infant
and child restraint systems. Refer to ISOFIX —
Child Seat Anchorage System for more infor-
mation.
NOTE:
The Advanced Front Air Bags have a multi-
stage inflator design. This allows the air bag
to have different rates of inflation based on
the severity and type of collision.

The first stage inflator is triggered immediately
during an impact that requires air bag deploy-
ment. This low output is used in less severe
collisions. A higher energy output is used for
more severe collisions.
WARNING!
•No objects should be placed over or near
the air bag on the instrument panel, be-
cause any such objects could cause harm if
the vehicle is in a collision severe enough
to cause the air bag to inflate.
• Do not put anything on or around the air
bag covers or attempt to open them manu-
ally. You may damage the air bags and you
could be injured because the air bags may
no longer be functional. The protective cov-
ers for the air bag cushions are designed to
open only when the air bags are inflating.
• Do not drill, cut or tamper with the knee
bolster in any way.
• Do not mount any accessories to the knee
bolster such as alarm lights, stereos, citi-
zen band radios, etc. Supplemental Seat-Mounted Side Air Bags
(SAB)
Supplemental Seat-Mounted Side Air Bags
(SAB) may provide enhanced protection to
help protect an occupant during a side impact.
The SAB is marked with an air bag label sewn
into the outboard side of the front seats.
When the air bag deploys, it opens the seam
between the front and side of the seat’s trim
cover. Each air bag deploys independently; a
left side impact deploys the left air bag only
and a right-side impact deploys the right air
bag only. Supplemental Side Air Bag Inflatable
Curtain (SABIC)
SABIC air bags may offer side-impact and
vehicle rollover protection to front and rear seat
outboard occupants in addition to that pro-
vided by the body structure. Each air bag
features inflated chambers placed adjacent to
the head of each outboard occupant that re-
duce the potential for side-impact head inju-
ries. The SABIC deploy downward, covering
both windows on the impact side.

WARNING!
Infants in rear-facing child restraints should
never ride in the front seat of a vehicle with a
passenger Advanced Front Air Bag. An air bag
deployment can cause severe injury or death
to infants in that position.
Children that are not big enough to wear the
vehicle seat belt properly (see Section on Child
Restraints) should be secured in the rear seat
in child restraints or belt-positioning booster
seats. Older children who do not use child
restraints or belt-positioning booster seats
should ride properly buckled up in the rear
seat. Never allow children to slide the shoulder
belt behind them or under their arm.
You should read the instructions provided with
your child restraint to make sure that you are
using it properly.
All occupants should always wear their lap and
shoulder belts properly.
The driver and front passenger seats should be
moved back as far as practical to allow the
Advanced Front Air Bags room to inflate. Do not lean against the door or window. If your
vehicle has side air bags, and deployment
occurs, the side air bags will inflate forcefully
into the space between you and the door.
If the air bag system in this vehicle needs to be
modified to accommodate a disabled person,
contact the Customer Center. Phone numbers
are provided under
If You Need Assistance.
WARNING!
•Relying on the air bags alone could lead to
more severe injuries in a collision. The air
bags work with your seat belt to restrain
you properly. In some collisions, the air
bags won’t deploy at all. Always wear your
seat belts even though you have air bags.
• Being too close to the steering wheel or
instrument panel during Advanced Front Air
Bag deployment could cause serious injury,
including death. Air Bags need room to
inflate. Sit back, comfortably extending
your arms to reach the steering wheel or
instrument panel.
(Continued)
WARNING!(Continued)
• The Supplemental Side Air Bag Inflatable
Curtain (SABIC) and Supplemental Seat-
Mounted Side Air Bag (SAB) also need
room to inflate. Do not lean against the
door or window. Sit upright in the center of
the seat.
• Being too close to the Supplemental Side
Air Bag Inflatable Curtain (SABIC) and/or
Seat-Mounted Side Air Bag (SAB) during
deployment could cause you to be severely
injured or killed.
Air Bag Deployment Sensors And
Controls
Occupant Restraint Controller (ORC)
The ORC is part of a regulated safety system
required for this vehicle.
The ORC determines if deployment of the front
and/or side air bags in a frontal or side collision
is required. Based on the impact sensor’s sig-
nals, a central electronic ORC deploys the
Advanced Front Air Bags, Supplemental Driver
Side Knee Air Bag, Supplemental Side Air Bag

Driver And Passenger Advanced Front Air
Bag Inflator Units
The Driver and Passenger Advanced Front Air
Bag Inflator Units are located in the center of
the steering wheel and on the right side of the
instrument panel. When the ORC detects a
collision requiring the Advanced Front Air
Bags, it signals the inflator units. A large quan-
tity of non-toxic gas is generated to inflate the
Advanced Front Air Bags. Different air bag
inflation rates are possible, based on the colli-
sion type and severity. The steering wheel hub
trim cover and the upper right side of the
instrument panel separate and fold out of the
way as the air bags inflate to their full size. The
air bags fully inflate in about 50 to 70 millisec-
onds. This is about half of the time it takes to
blink your eyes. The air bags then quickly
deflate while helping to restrain the driver and
front passenger.
The Advanced Front Air Bag gas is vented
through the vent holes in the sides of the air
bag. In this way, the air bags do not interfere
with your control of the vehicle.Supplemental Driver Side Knee Air Bag
Inflator Unit
The Supplemental Driver Side Knee Air Bag
unit is located in the instrument panel trim
beneath the steering column. When the ORC
detects a collision requiring the air bag, it
signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the
Supplemental Driver Side Knee Air Bag. The
trim cover separates and folds out of the way
allowing the air bag to inflate to the full size. The
air bag fully inflates in about 15 to 20 millisec-
onds.
Supplemental Seat-Mounted Side Air Bag
(SAB) Inflator Units
The Supplemental Seat-Mounted Side Air Bags
are designed to activate only in certain side
collisions.
The ORC determines if a side collision requires
the side air bags to inflate, based on the
severity and type of collision.
Based on the severity and type of collision, the
side air bag inflator on the crash side of the
vehicle may be triggered, releasing a quantity
of non-toxic gas. The inflating SAB exitsthrough the seat seam into the space between
the occupant and the door. The SAB fully inflate
in about 10 milliseconds. The side air bag
moves at a very high speed and with such a
high force that it could injure you if you are not
seated properly, or if items are positioned in the
area where the side air bag inflates. This espe-
cially applies to children.
Supplemental Side Air Bag Inflatable
Curtain (SABIC) Inflator Units
During collisions where the impact is confined
to a particular area of the side of the vehicle,
the ORC may deploy the SABIC air bags,
depending on the severity and type of collision.
In these events, the ORC will deploy the SABIC
only on the impact side of the vehicle.
A quantity of non-toxic gas is generated to
inflate the side curtain air bag. The inflating
side curtain air bag pushes the outside edge of
the headliner out of the way and covers the
window. The air bag inflates in about 30 milli-
seconds (about one-quarter of the time that it
takes to blink your eyes) with enough force to
injure you if you are not belted and seated
properly, or if items are positioned in the area
where the side curtain air bag inflates. This

WARNING!
•Do not leave children or animals inside
parked vehicles in hot weather. Interior
heat build-up may cause serious injury or
death.
• It is extremely dangerous to ride in a cargo
area, inside or outside of a vehicle. In a
collision, people riding in these areas are
more likely to be seriously injured or killed.
• Do not allow people to ride in any area of
your vehicle that is not equipped with seats
and seat belts.
• Be sure everyone in your vehicle is in a
seat and using a seat belt properly.
Exhaust Gas
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you uncon-
scious and can eventually poison you. To
avoid breathing (CO), follow these safety tips: Do not run the engine in a closed garage or in
confined areas any longer than needed to
move your vehicle in or out of the area.
If it is necessary to sit in a parked vehicle with
the engine running, adjust your heating or
cooling controls to force outside air into the
vehicle. Set the blower at high speed.
If you are required to drive with the trunk/liftgate
open, make sure that all windows are closed
and the climate control BLOWER switch is set
at high speed. DO NOT use the recirculation
mode.
The best protection against carbon monoxide
entry into the vehicle body is a properly main-
tained engine exhaust system.
Whenever a change is noticed in the sound of
the exhaust system, when exhaust fumes can
be detected inside the vehicle, or when the
underside or rear of the vehicle is damaged,
have a competent mechanic inspect the com-
plete exhaust system and adjacent body areas
for broken, damaged, deteriorated, or misposi-
tioned parts. Open seams or loose connections
could permit exhaust fumes to seep into the
passenger compartment. In addition, inspect the exhaust system each time the vehicle is
raised for lubrication or oil change. Replace as
required.
Safety Checks You Should Make
Inside The Vehicle
Seat Belts
Inspect the belt system periodically, checking
for cuts, frays, and loose parts. Damaged parts
must be replaced immediately. Do not disas-
semble or modify the system.
Front seat belt assemblies must be replaced
after a collision. Rear seat belt assemblies must
be replaced after a collision if they have been
damaged (i.e., bent retractor, torn webbing,
etc.). If there is any question regarding belt or
retractor condition, replace the belt.
Air Bag Warning Light
The light should come on and remain on for four
to eight seconds as a bulb check when the
ignition switch is first turned ON. If the light is
not lit during starting, see your authorized
dealer. If the light stays on, flickers, or comes
on while driving, have the system checked by
an authorized dealer.

MIRRORS
Inside Day/Night Mirror
A single ball joint mirror is provided in the
vehicle. It is a twist on mirror that has a fixed
position. The mirror head can be adjusted up,
down, left, and right for various drivers. The
mirror should be adjusted to center on the view
through the rear window.
Headlight glare from vehicles behind you can
be reduced by moving the small control under
the mirror to the night position (toward the rear
of the vehicle). The mirror should be adjusted
while set in the day position (toward the wind-
shield).
Automatic Dimming Mirror — If
Equipped
This mirror automatically adjusts for headlight
glare from vehicles behind you. You can turn
the feature on or off by pressing the button at
the base of the mirror. A light in the button will
illuminate to indicate when the dimming feature
is activated. The mirror is twisted on the wind-
shield button counterclockwise and requires no
tools for mounting.
CAUTION!
To avoid damage to the mirror during clean-
ing, never spray any cleaning solution directly
onto the mirror. Apply the solution onto a clean
cloth and wipe the mirror clean.
Outside MirrorsTo receive maximum benefit, adjust the outside
mirrors to center on the adjacent lane of traffic
with a slight overlap of the view obtained on the
inside mirror.
WARNING!
Vehicles and other objects seen in the pas-
senger side convex mirror will look smaller
and farther away than they really are. Relying
too much on your passenger side convex
mirror could cause you to collide with another
vehicle or other object. Use your inside mirror
when judging the size or distance of a vehicle
seen in the passenger side convex mirror.
Some vehicles will not have a convex passen-
ger side mirror.
