THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 13

NOTE:
•The power liftgate buttons will not operate if the
vehicle is in gear or the vehicle speed is above 0 mph
(0 km/h).
• The power liftgate will not operate in temperatures
below 22°F (30°C) or temperatures 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 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 electronic liftgate release is pushed while the
power liftgate is closing, the liftgate will reverse to the
full open position.
• If the electronic liftgate release is pushed while the
power liftgate is opening, the liftgate motor will dis-
engage 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 manu-
ally.
48 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.

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.
WARNING!
•No objects should be placed over or near the air bag
on the instrument panel, because 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 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.

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 SAB 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

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 Knee
Air Bag are designed to provide additional protection by
supplementing the seat belts in certain frontal collisions
depending on several factors, including the severity andtype of collision. Advanced Front Air Bags are not
expected to reduce the risk of injury in rear, side, or
rollover collisions.
The Advanced Front Air Bags and Supplemental Driver
Knee Air Bag 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.
The side air bags will not deploy in all side collisions.
Side air bag deployment will depend on the severity and
type of collision.
76 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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
turns on the Air Bag Warning Light, either momentarily
or continuously. A single chime will sound if the light
comes on again after initial startup.
It also includes diagnostics that will illuminate the instru-
ment cluster Air Bag Warning Light if a malfunction is
noted that could affect the air bag system. The diagnos-
tics also record the nature of the malfunction.

enough force to injure you if you are not belted and
seated properly, or if items are positioned in the area
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
In front and side impacts, impact sensors 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 the
event 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.
