WARNING!(Continued)
only used to install rear-facing or forward-facing
child restraints that have a harness for restraining
the child.
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 requirethe Active Head Restraints (AHR) to deploy. If a rear
impact requires deployment, both the driver and front
passenger 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 sever-
ity and type of the impact.

WARNING!
All occupants, including the driver, should not oper-
ate a vehicle or sit in a vehicle’s seat until the head
restraints are placed in their proper positions in order
to minimize the risk of neck injury in the event of a
collision.
NOTE:For more information on properly adjusting and
positioning the head restraint, refer to “Adjusting Active
Head Restraints” in “Understanding The Features Of
Your Vehicle.”
Resetting Active Head Restraints (AHR)
If the Active Head Restraints are triggered in a collision,
you must reset the head restraint on the driver ’s and
front passenger ’s seat before driving. You can recognize
when the Active Head Restraint has been triggered by the
fact that they have moved forward (as shown in step
three of the resetting procedure).

1. Grasp the deployed AHR from the rear seat.
2. Position the hands on the top of the deployed AHR at
a comfortable position.3. Pull down then rearward towards the rear of the
vehicle then down to engage the locking mechanism.

NOTE:
•If you have difficulties or problems resetting the Active
Head Restraints, see an authorized dealer.
•For safety reasons, have the Active Head Restraints
checked by a qualified specialist at an authorized
dealer.
Supplemental Restraint System (SRS)
Air Bag System Components
Your vehicle may be equipped with the following air bag
system components:
•Occupant Restraint Controller (ORC)
•Air Bag Warning Light
•Steering Wheel and Column
•Instrument Panel•Knee Impact Bolsters
•Advanced Front Air Bags
•Supplemental Side Air Bags
•Supplemental Knee Air Bags
•Front and Side Impact Sensors
•Seat Belt Pretenioners
•Seat Belt Buckle Switch
•Seat Track Position Sensors
Advanced Front Air Bags
This vehicle has Advanced Front Air Bags 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 Air Bag is mounted in the
instrument panel, above the glove compartment. The
2

words “SRS AIRBAG” or “AIRBAG” are embossed on
the air bag covers.WARNING!
•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.
•Never place a rear-facing child restraint in front of
an air bag. A deploying Passenger Advanced Front
Air Bag can cause death or serious injury to a child
12 years or younger, including a child in a rear-
facing child restraint.
•Only use a rear-facing child restraint in a vehicle
with a rear seat.
Advanced Front Air Bag Features
The Advanced Front Air Bag system has multistage
driver and front passenger air bags. 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 or other system components.
The first stage inflator is triggered immediately during an
impact that requires air bag deployment. A low energy
output is used in less severe collisions. A higher energy
output is used for more severe collisions.
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 Air Bags 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 buckled. The seat
belt buckle switch may adjust the inflation rate of the
Advanced Front Air Bags.WARNING!
•No objects should be placed over or near the air
bag on the instrument panel or steering wheel,
because any such objects could cause harm if the
vehicle is in a collision severe enough to cause the
air bags to inflate.
•Do not put anything on or around the air bag
covers or attempt to open them manually. You may
damage the air bags and you could be injured
because the air bags may no longer be functional.
The protective covers for the air bag cushions are
designed to open only when the air bags are
inflating.
•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, air bags won’t deploy at all. Al-
ways wear your seat belts even though you have air
bags.
Advanced Front Air Bag Operation
Advanced Front Air Bags are designed to provide addi-
tional protection by supplementing the seat belts. Ad-
vanced Front Air Bags are not expected to reduce the risk
of injury in rear, side, or rollover collisions. The Ad-
vanced Front Air Bags 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 Air Bags may deploy in crashes
with little vehicle front-end damage but that produce a
severe initial deceleration.Because air bag sensors measure vehicle deceleration
over time, vehicle speed and damage by themselves are
not good indicators of whether or not an air bag should
have deployed.
Seat belts are necessary for your protection in all colli-
sions, and also are needed to help keep you in position,
away from an inflating air bag.
When the ORC detects a collision requiring the Ad-
vanced Front Air Bags, it signals the inflator units. A large
quantity of non-toxic gas is generated to inflate the
Advanced Front Air Bags.
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 Advanced
Front Air Bags fully inflate in less time than it takes to
blink your eyes. The air bags then quickly deflate while
helping to restrain the driver and front passenger.
