•If the liftgate handle is pulled while the
power liftgate is closing, the liftgate will
reverse to the full open position.
• If the liftgate handle is pulled while the
power liftgate is opening, the liftgate mo-
tor will disengage to allow manual opera-
tion.
• The power liftgate buttons will not oper-
ate if the vehicle is in gear or the vehicle
speed is above 0 mph (0 km/h).
• The power liftgate will not operate in tem-
peratures below 22°F ( 30°C) or tem-
peratures above 150°F (65°C). Be sure to
remove any buildup of snow or ice from
the liftgate before pressing any of the
power liftgate switches.
•
If the power liftgate encounters multiple
obstructions within the same cycle, the
system will automatically stop and the lift-
gate must be opened or closed manually.
• 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 Airbags 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 airbag
• Supplemental Side Airbag Inflatable Cur-
tains (SABIC) for the driver and passengers
seated next to a window — if equipped
• Supplemental Seat-Mounted Side Airbags
(SAB) — if equipped
• An energy-absorbing steering column and
steering wheel
• Knee bolsters/blockers for front seat occu-
pants
• Front seat belts incorporate pretensioners to
enhance occupant protection by managing
occupant energy during an impact event
•
All seat belt systems (except the driver’s)
include Automatic Locking Retractors (ALRs),
which lock the seat belt webbing into position
by extending the belt all the way out and then
28

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 Airbags have a multi-
stage inflator design. This allows the airbag
to have different rates of inflation based on
the severity and type of collision.
Please pay close attention to the information in
this section. It tells you how to use your restraint
system properly, to keep you and your passen-
gers as safe as possible.
WARNING!
In an accident, you and your passengers can
suffer much greater injuries if you are not
properly buckled up. You can strike the interior
of your vehicle or other passengers, or you
can be thrown out of the vehicle. Always be
sure you and others in your vehicle are buck-
led up properly.
Buckle up even though you are an excellent
driver, even on short trips. Someone on the
road may be a poor driver and cause an
accident that includes you. This can happen far
away from home or on your own street.
Research has shown that seat belts save lives,
and they can reduce the seriousness of injuries
in an accident. Some of the worst injuries
happen when people are thrown from the ve-
hicle. Seat belts reduce the possibility of ejec-
tion and the risk of injury caused by striking the
inside of the vehicle. Everyone in a motor
vehicle should be belted at all times.Lap/Shoulder BeltsAll seating positions in your vehicle are
equipped with lap/shoulder belts. The belt
webbing retractor is designed to lock during
very sudden stops or accidents. This feature
allows the shoulder part of the belt to move
freely with you under normal conditions. How-
ever, in an accident the belt will lock and
reduce the risk of you striking the inside of the
vehicle or being thrown out.
WARNING!
•Wearing a seat belt incorrectly is dangerous.
Seat belts are designed to go around the
large bones of your body. These are the
strongest parts of your body and can take the
forces of an accident the best. Wearing your
belt in the wrong place could make your
injuries in an accident much worse. You
might suffer internal injuries, or you could
even slide out of part of the belt. Follow these
instructions to wear your seat belt safely and
to keep your passengers safe, too.

section so as to not activate the ALR. If the ALR
is activated you will hear a ratcheting sound as
the belt retracts. Allow the webbing to retract
completely in this case and then carefully pull
out only the amount of webbing necessary to
comfortably wrap around the occupants mid-
section. Slide the latch plate into the buckle
until you hear aclick. 
Seat Belt PretensionersThe seat belts for both front seating positions
are equipped with pretensioning devices that
are designed to remove slack from the seat belt
in the event of an accident. These devices
improve the performance of the seat belt by
assuring that the belt is tight about the occu-
pant early in an accident. Pretensioners work
for all size occupants, including those in child
restraints.
NOTE:
These devices are not a substitute for
proper seat belt placement by the occupant.
The seat belt still must be worn snugly and
positioned properly.
The pretensioners are triggered by the Occu-
pant Restraint Controller (ORC). Like the air- bags, the pretensioners are single use items. A
deployed pretensioner or a deployed airbag
must be replaced immediately.
Supplemental Active Head
Restraints (AHR)
These head restraints are passive, deployable
components, and vehicles with this equipment
cannot be readily identified by any markings,
only through visual inspection of the head re-
straint. The head restraint will be split in two
halves, with the front half being soft foam and
trim, the back half being decorative plastic.
How the Active Head Restraints (AHR)
Work
The Occupant Restraint Controller (ORC) de-
termines whether the severity, or type of rear
impact will require the Active Head Restraints
(AHR) to deploy. If a rear impact requires
deployment, both the driver and front passen-
ger seat AHRs will be deployed.
When AHRs deploy during a rear impact, the
front half of the head restraint extends forward
to minimize the gap between the back of the
occupant’s head and the AHR. This system is
designed to help prevent or reduce the extent
of injuries to the driver and front passenger in
certain types of rear impacts.
NOTE:
The Active Head Restraints (AHR) may or
may not deploy in the event of a front or side
impact. However if during a front impact, a
secondary rear impact occurs, the AHR may
deploy based on the severity and type of the
impact.

Pregnant women should wear the lap part of
the belt across the thighs and as snug across
the hips as possible. Keep the belt low so that
it does not come across the abdomen. That
way the strong bones of the hips will take the
force if there is an accident.
Supplemental Restraint System
(SRS) — Airbags
This vehicle has Advanced Front Airbags for
both the driver and front passenger as a
supplement to the seat belt restraint systems.
The driver’s Advanced Front Airbag is mounted
in the center of the steering wheel. The passen-
ger’s Advanced Front Airbag is mounted in the
instrument panel, above the glove compart-
ment. The words SRS AIRBAG are embossed
on the airbag covers. In addition, the vehicle is
equipped with a driver side knee airbag
mounted in the instrument panel below the
steering column.The Advanced Front Airbags have a multistage
inflator design. This allows the airbag to have
different rates of inflation based on the severity
and type of collision.
This vehicle is equipped with Supplemental
Side Airbag Inflatable Curtains (SABIC) to pro-
tect the driver, front, and rear passengers sit-
ting next to a window. The SABIC airbags, are
located above the side windows and their
covers are also labeled: SRS AIRBAG.This vehicle is equipped with Supplemental
Seat-Mounted Side Airbags (SAB) to provide
enhanced protection for an occupant during a
side impact. The Supplemental Seat-Mounted
Side Airbags are located in the outboard side
of the front seats.
NOTE:
•
Airbag covers may not be obvious in the
interior trim; but they will open during
airbag deployment.
• After any accident, the vehicle should be
taken to an authorized dealer immedi-
ately.

Advanced Front Airbag FeaturesThe Advanced Front Airbag system has multi-
stage driver and front passenger airbags. This
system provides output appropriate to the se-
verity and type of collision as determined by
the Occupant Restraint Controller (ORC), which
may receive information from the front impact
sensors.
The first stage inflator is triggered immediately
during an impact that requires airbag 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 airbag on the instrument panel, be-
cause any such objects could cause harm if
the vehicle is in a collision severe enough
to cause the airbag to inflate.
• Do not put anything on or around the airbag
covers or attempt to open them manually.
You may damage the airbags and you
could be injured because the airbags may
no longer be functional. The protective cov-
ers for the airbag cushions are designed to
open only when the airbags 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 Airbags
(SAB)
Supplemental Seat-Mounted Side Airbags pro-
vide enhanced protection to help protect an
occupant during a side impact. The Supple-
mental Seat-Mounted Side Airbag is marked
with an airbag label sewn into the outboard
side of the front seats.
When the airbag deploys, it opens the seam
between the front and side of the seat’s trim
cover. Each airbag deploys independently, that
is a left side impact deploys the left airbag only
and a right-side impact deploys only the right
airbag.

Supplemental Side Airbag Inflatable
Curtain (SABIC)
SABIC airbags may offer side-impact and ve-
hicle rollover protection to front and rear seat
outboard occupants in addition to that pro-
vided by the body structure. Each airbag fea-
tures inflated chambers placed adjacent to the
head of each outboard occupant that reduce
the potential for side-impact head injuries. The
curtains deploy downward, covering both win-
dows on the impact side.NOTE:
•
Should a vehicle rollover occur, the pre-
tensioners and/or SAB and SABIC air-
bags on both sides of the vehicle may
deploy.
• Airbag covers may not be obvious in the
interior trim; but they will open during
airbag deployment.
• Being too close to the SAB and SABIC
airbags during deployment could cause
you to be severely injured or killed.
The system includes side impact sensors ad-
jacent to both front and rear seat occupants
that are calibrated to deploy the SABIC airbags
during impacts that require airbag occupant
protection.WARNING!
• If your vehicle is equipped with left and right
Supplemental Side Airbag Inflatable Cur-
tain (SABIC), do not stack luggage or other
cargo up high enough to block the location
of the SABIC. The area where the SABIC is
located should remain free from any ob-
structions.
• Do not use accessory seat covers or place
objects between you and the side airbags;
the performance could be adversely af-
fected and/or objects could be pushed into
you, causing serious injury.
Supplemental Driver Side Knee Airbag
The supplemental driver side knee airbag pro-
vides enhanced protection and works together
with the advanced driver side frontal airbag
during a frontal impact.
Knee Impact Bolster
The Knee Impact Bolster helps protect the
knees of the passenger side front passenger
by positioning the passenger for the best inter-
action with the Advanced Front Airbags.

Along with seat belts and pretensioners, Ad-
vanced Front Airbags work with the driver side
knee airbag and the passenger side knee
bolster to provide improved protection for the
driver and front passenger. Side airbags also
work with seat belts to improve occupant pro-
tection.
Here are some simple steps you can take to
minimize the risk of harm from a deploying
airbag:
Children 12 years old and under should always
ride buckled up in a rear seat.
WARNING!
Infants in rear-facing child restraints should
never ride in the front seat of a vehicle with a
passenger Advanced Front Airbag. An airbag
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 Airbags room to inflate.
Do not lean against the door or window. If your
vehicle has side airbags, and deployment oc-
curs, the side airbags will inflate forcefully into
the space between you and the door.
If the airbag 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 airbags alone could lead to
more severe injuries in a collision. The
airbags 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 airbags.
• Being too close to the steering wheel or
instrument panel during Advanced Front
Airbag deployment could cause serious
injury, including death. Airbags need room
to inflate. Sit back, comfortably extending
your arms to reach the steering wheel or
instrument panel.
• The Supplemental Side Airbag Inflatable
Curtain (SABIC) and Supplemental Seat-
Mounted Side Airbag (SAB) also need
room to inflate. Do not lean against the
door or window. Sit upright in the center of
the seat.

WARNING!(Continued)
• Being too close to the Supplemental Side
Airbag Inflatable Curtain (SABIC) and/or
Seat-Mounted Side Airbag (SAB) during
deployment could cause you to be severely
injured or killed.
Airbag 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 airbags in a frontal or side collision
is required. Based on the impact sensors sig-
nals, a central electronic ORC deploys the
Advanced Front Airbags, Supplemental Driver
Side Knee Airbag, Supplemental Side Airbag
Inflatable Curtain (SABIC), Supplemental Seat-
Mounted Side Airbags (SAB), and front seat
belt pretensioners, as required, depending on
the severity and type of impact. Advanced Front Airbags and knee airbag are
designed to provide additional protection by
supplementing the seat belts in certain frontal
collisions depending on the severity and type
of collision. Advanced Front Airbags are not
expected to reduce the risk of injury in rear, or
side collisions.
The Advanced Front Airbags and knee airbag
will not deploy in all frontal collisions, including
some that may produce substantial vehicle
damage — for example, some pole collisions,
truck underrides, and angle offset collisions.
On the other hand, depending on the type and
location of impact, Advanced Front Airbags
may deploy in crashes with little vehicle front-
end damage but that produce a severe initial
deceleration.
The side airbags will not deploy in all side
collisions. Side airbag deployment will depend
on the severity and type of collision.
Because airbag sensors measure vehicle de-
celeration over time, vehicle speed and dam-
age by themselves are not good indicators of
whether or not an airbag should have de-
ployed.Seat belts are necessary for your protection in
all accidents, and also are needed to help keep
you in position, away from an inflating airbag.
The ORC monitors the readiness of the elec-
tronic parts of the airbag system whenever the
ignition switch is in the START or ON/RUN
position. If the key is in the LOCK position, in
the ACC position, or not in the ignition, the
airbag system is not on and the airbags will not
inflate.
The ORC contains a backup power supply
system that may deploy the airbags even if the
battery loses power or it becomes discon-
nected prior to deployment.
Also, the ORC turns on the Airbag
Warning Light in the instrument
panel for approximately four to
eight seconds for a self-check
when the ignition is first turned to
the ON/RUN position. After the
self-check, the Airbag Warning Light will turn
off. If the ORC detects a malfunction in any part
of the system, it turns on the Airbag Warning
Light, either momentarily or continuously. A
41

single chime will sound if the light comes on
again after initial startup.
It also includes diagnostics that will illuminate
the instrument cluster Airbag Warning Light if a
malfunction is noted that could affect the airbag
system. The diagnostics also record the nature
of the malfunction.
WARNING!
Ignoring the Airbag Warning Light in your
instrument panel could mean you won’t have
the airbags to protect you in a collision. If the
light does not come on, stays on after you
start the vehicle, or if it comes on as you drive,
have an authorized dealer service the airbag
system immediately.
Driver and Passenger Advanced Front
Airbag Inflator Units
The Driver and Passenger Advanced Front
Airbag Inflator Units are located in the center of
the steering wheel and the right side of the
instrument panel. When the ORC detects a
collision requiring the Advanced Front Airbags,
it signals the inflator units. A large quantity of non-toxic gas is generated to inflate the Ad-
vanced Front Airbags. Different airbag inflation
rates are possible, based on the collision 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 airbags
inflate to their full size. The airbags fully inflate
in about 50 to 70 milliseconds. This is about half
of the time it takes to blink your eyes. The
airbags then quickly deflate while helping to
restrain the driver and front passenger.
The Advanced Front Airbag gas is vented
through the vent holes in the sides of the
airbag. In this way, the airbags do not interfere
with your control of the vehicle.
Supplemental Driver Side Knee Airbag
Inflator Unit
The driver side knee airbag unit is located in
the instrument panel trim beneath the steering
column. When the ORC detects a collision
requiring the airbag, it signals the inflator units.
A large quantity of non-toxic gas is generated
to inflate the knee airbag. The trim cover sepa-
rates and folds out of the way allowing the
airbag to inflate to the full size. The airbag fully
inflates in about 15 to 20 milliseconds.Supplemental Seat-Mounted Side Airbag
(SAB) Inflator Units
The Supplemental Seat-Mounted Side Airbags
are designed to activate only in certain side
collisions.
The ORC determines if a side collision requires
the side airbags to inflate based on the severity
and type of collision.
Based on the severity and type of collision, the
side airbag inflator on the crash side of the
vehicle may be triggered, releasing a quantity
of non-toxic gas. The inflating side airbag exits
through the seat seam into the space between
the occupant and the door. The side airbags
fully inflate in about 10 milliseconds. The side
airbag 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 posi-
tioned in the area where the side airbag in-
flates. This especially applies to children.
Supplemental Side Airbag 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 airbags, de-
