THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 13

•If the power liftgate encounters multiple obstructions
within the same cycle, the system will automatically
stop and the liftgate must be opened or closed manu-
ally.
•If your liftgate is power closing and you put the
vehicle in gear, the liftgate will continue to power
close. However, vehicle movement may result in a
detection of an obstruction.
WARNING!
•Driving with the liftgate open can allow poison-
ous 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.(Continued)
WARNING! (Continued)
•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 tempera-
ture, it may be necessary to assist the props when
opening the liftgate in cold weather.
OCCUPANT RESTRAINTS
Some 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 passen-
ger
48 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

•Supplemental Active Head Restraints (AHR) located
on top of the front seats (integrated into the head
restraint)
•Supplemental Side Airbag Inflatable Curtains (SABIC)
for the driver and passengers seated next to a window
•Supplemental Seat-Mounted Side Airbags (SAB)
•An energy-absorbing steering column and steering
wheel
•Knee bolsters for front seat occupants
•Front seat belts incorporate pretensioners that may
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 beltall 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
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 passengers as safe as
possible.
If you will be carrying children too small for adult-sized
seat belts, the seat belts or the Lower Anchors and Tether
for CHildren (LATCH) feature also can be used to hold
infant and child restraint systems. For more information
on LATCH, see Lower Anchors and Tether for CHildren
(LATCH).
NOTE: 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.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 49

Here are some simple steps you can take to minimize the
risk of harm from a deploying airbag:
1.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 posi-
tion.
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.
If a child from 1 to 12 years old (not in a rear facing child
seat) must ride in the front passenger seat, move the seat
as far back as possible and use the proper child restraint.
(Refer to “Child Restraints”)
You should read the instructions provided with your
child restraint to make sure that you are using it properly.
2.
All occupants should always wear their lap and
shoulder belts properly.
3. The driver and front passenger seats should be
moved back as far as practical to allow the Advanced
Front Airbags room to inflate.
50 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

4.Do not lean against the door or window. If your
vehicle has side airbags, and deployment occurs, the
side airbags will inflate forcefully into the space be-
tween you and the door.
5. 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 airbags won’t deploy at all.
Always wear your seat belts even though you have
airbags.
(Continued)
WARNING! (Continued)
•Being too close to the steering wheel or instrument
panel during Advanced Front Airbag 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.
•Supplemental Side Airbag Inflatable Curtain
(SABIC) and Seat-Mounted Side Airbags (SAB)
also need room to inflate. Do not lean against the
door or window. Sit upright in the center of the
seat.
•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 buckled up properly.

Seat Belt Pretensioners
The 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 may improve the performance of
the seat belt by assuring that the belt is tight about the
occupant 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 Occupant Re-
straint Controller (ORC). Like the airbags, the pretension-
ers 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 compo-
nents, and vehicles with this equipment cannot be readily
identified by any markings, only through visual inspec-
tion of the head restraint. 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) determines
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
passenger seat AHRs will be deployed.

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 Air-
bag is mounted in the center of the steering wheel. The
passenger’s Advanced Front Airbag is mounted in the
instrument panel, above the glove compartment. The
words SRS AIRBAG are embossed on the airbag covers.NOTE:These airbags are certified to the new Federal
regulations for Advanced Airbags.
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.

68 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

This vehicle may be equipped with driver and/or front
passenger seat track position sensors that may adjust the
inflation rate of the Advanced Front Airbags based upon
seat position.
This vehicle may be equipped with a driver and/or front
passenger seat belt buckle switch that detects whether
the driver or front passenger seat belt is fastened. The
seat belt buckle switch may adjust the inflation rate of the
Advanced Front Airbags.
This vehicle is equipped with Supplemental Side Airbag
Inflatable Curtains (SABIC) to protect the driver, front,
and rear passengers sitting 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 pro-
tection for an occupant during a side impact. The Supple-
mental 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 immediately.

Advanced Front Airbag Features
The Advanced Front Airbag system has multistage driver
and front passenger airbags. This system provides output
appropriate to the severity 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 deployment. This low output
is used in less severe collisions. A higher energy output is
used for more severe collisions.
70 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
•No objects should be placed over or near the airbag
on the instrument panel, because 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 covers for the airbag cushions are
designed to open only when the airbags are inflat-
ing.
•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, citizen band radios,
etc.
