THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 13

•If anything obstructs the power liftgate while it is
closing or opening, the liftgate will automatically
reverse to the closed or open position, provided it
meets sufficient resistance.
•There are also pinch sensors attached to the side of the
liftgate. Light pressure anywhere along these strips
will cause the liftgate to return to the open position.
•The power liftgate must be in the full open position for
rear liftgate close button on the left rear trim, near the
liftgate opening to operate. If the liftgate is not fully
open, press the Liftgate button on the Key Fob to fully
open the liftgate, and then press it again to close.
•
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 motor will disengage to allow
manual operation.•If the power liftgate encounters multiple obstructions
within the same cycle, the system will automatically
stop and the liftgate 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, vehicle 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.

50 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

NOTE:The Driver and Front Passenger Advanced Front
Air Bags are certified to the new Federal regulations for
Advanced Air Bags.
The Advanced Front Air Bags have a multistage inflator
design. This allows the air bag to have different rates of
inflation based on several factors, including the severity
and type of collision.
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 fastened. The
seat belt buckle switch may adjust the inflation rate of the
Advanced Front Air Bags.This vehicle is equipped with Supplemental Side Air Bag
Inflatable Curtains (SABIC) to protect the driver, front,
and rear passengers sitting next to a window. The SABIC
air bags, are located above the side windows and their
covers are also labeled: SRS AIRBAG.
This vehicle is equipped with Supplemental Seat-
Mounted Side Air Bags (SAB) to provide enhanced
protection for an occupant during a side impact. The
Supplemental Seat-Mounted Side Air Bags are located in
the outboard side of the front seats.
NOTE:
•Air Bag covers may not be obvious in the interior trim,
but they will open during air bag deployment.
•After any collision, the vehicle should be taken to an
authorized dealer immediately.

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 Bolster
•Driver Advanced Front Air Bag
•Passenger Advanced Front Air Bag
•Supplemental Seat-Mounted Side Air Bags (SAB)
•Supplemental Side Air Bag Inflatable Curtains (SABIC)
•Supplemental Driver Side Knee Air Bag•Front and Side Impact Sensors
•Front Seat Belt Pretensioners, Seat Belt Buckle Switch,
and Seat Track Position Sensors
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.
The first stage inflator is triggered immediately during an
impact that requires air bag deployment. This low output
is used in less severe collisions. A higher energy output is
used for more severe collisions.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 71

NOTE:
•Air Bag covers may not be obvious in the interior trim,
but they will open during air bag deployment.
•Being too close to the SAB and SABIC air bags during
deployment could cause you to be severely injured or
killed.
•Should a vehicle rollover occur, the pretensioners
and/or SAB and SABIC air bags on both sides of the
vehicle may deploy.
The system includes side impact sensors that are cali-
brated to deploy the Supplemental Seat-Mounted Side
Air Bags and SABIC air bags during impacts that require
side air bag occupant protection.WARNING!
•Your vehicle is equipped with left and right
SABIC, do not stack luggage or other cargo up high
enough to block the location of the SABIC. The
area where the side curtain air bag is located
should remain free from any obstructions.
•Do not use accessory seat covers or place objects
between you and the SAB; the performance could
be adversely affected and/or objects could be
pushed into you, causing serious injury.
•Your vehicle is equipped with SABIC air bags, do
not have any accessory items installed which will
alter the roof, including adding a sunroof to your
vehicle. Do not add roof racks that require perma-
nent attachments (bolts or screws) for installation
on the vehicle roof. Do not drill into the roof of the
vehicle for any reason.
74 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Always sit upright as possible with your back against the
seat back, use the seat belts properly, and use the
appropriate sized child restraint, infant restraint or
booster seat recommended for the size and weight of the
child.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees of the
driver and the front passenger, and position front occu-
pants for the best interaction with the Advanced Front
Air Bag.
Along with seat belts and pretensioners, Advanced Front
Air Bags work with the knee bolsters to provide im-
proved protection for the driver and front passenger. Side
air bags also work with seat belts to improve occupant
protection.
Air Bag Deployment Sensors And Controls
Occupant Restraint Controller (ORC)
The ORC is part of a Federally 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 signals, a central electronic
ORC deploys the Advanced Front Air Bags, SABIC air
bags, SAB air bags, and front seat belt pretensioners, as
required, depending on several factors, including the
severity and type of impact.
Advanced Front Air Bags and Supplemental Driver and
Front Passenger Knee Air Bags are designed to provide
additional protection by supplementing the seat belts in
certain frontal collisions depending on several factors,
including the severity and type of collision. Advanced
Front Air Bags are not expected to reduce the risk of
injury in rear, side, or rollover collisions.2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 75

The Advanced Front Air Bags and Supplemental Driver
and Front Passenger Knee Air Bags will not deploy in all
frontal collisions, including some that may produce sub-
stantial vehicle damage — for example, some pole colli-
sions, 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.
The side air bags will not deploy in all side collisions.
Side air bag deployment will depend on the severity and
type of collision.
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.
The ORC monitors the readiness of the electronic parts of
the air bag system whenever the ignition switch is in the
START or ON/RUN position. If the key is in the OFF
position, in the ACC position, or not in the ignition, the
air bag system is not on and the air bags will not inflate.
The ORC contains a backup power supply system that
may deploy the air bags even if the battery loses power or
it becomes disconnected prior to deployment.
Also, the ORC turns on the Air Bag Warning
Light in the instrument panel for approxi-
mately four to eight seconds for a self-check
when the ignition is first turned on. After the
self-check, the Air Bag Warning Light will turn off. If the
ORC detects a malfunction in any part of the system, it

where the SABIC inflates. This especially applies to
children. The SABIC is only about 3-1/2 in (9 cm) thick
when it is inflated.
Because air bag sensors estimate deceleration over time,
vehicle speed and damage are not good indicators of
whether or not an air bag should have deployed.
NOTE:In a rollover the pretensioners and/or SAB and
SABIC air bags, and driver/passenger knee air bags may
deploy on both sides of the vehicle.
Front And Side Impact Sensors — If Equipped
In front and side impacts, impact sensors — if equipped
can aid the ORC in determining appropriate response to
impact events.
Enhanced Accident Response System
In the event of an impact causing air bag deployment, if
the communication network remains intact, and the
power remains intact, depending on the nature of theevent the ORC will determine whether to have the
Enhanced Accident Response System perform the follow-
ing functions:
•Cut off fuel to the engine.
•Flash hazard lights as long as the battery has power or
until the ignition key is turned off.
•Turn on the interior lights, which remain on as long as
the battery has power or until the ignition key is
removed.
•Unlock the doors automatically.
In order to reset the Enhanced Accident Response System
functions after an event, the ignition switch must be
changed from IGN ON to IGN OFF.If A Deployment Occurs
The Advanced Front Air Bags are designed to deflate
immediately after deployment.
