Once the liftgate flipper glass has been
opened, connection to the rear window wiper is
interrupted, preventing activation of the rear
wiper blade while the flipper glass is open.
NOTE:
If a malfunction to the liftgate latch should
occur, an emergency liftgate latch release
can be used to open the liftgate. The emer-
gency liftgate latch release can be accessed
through a snap-in cover located on the lift-
gate trim panel.
WARNING!
Driving with the flipper glass open can allow
poisonous exhaust gases into your vehicle.
You and your passengers could be injured by
these fumes. Keep the flipper glass closed
when you are operating the vehicle.
Power Liftgate — If Equipped
The power liftgate may be opened
manually or by pressing the LIFT-
GATE button on the Remote Key-
less Entry (RKE) transmitter. Press
the LIFTGATE button on the RKEtransmitter twice within five seconds, to open
the power liftgate. Once the liftgate is open,
pressing the button twice within five seconds a
second time will close the liftgate.
The power liftgate may also be opened or
closed by pressing the LIFTGATE button lo-
cated on the front overhead console, or closed
by pressing the LIFTGATE button located on
left rear trim, near the liftgate opening. Pressing
the LIFTGATE button located on left rear trim
once will close the liftgate only, this button
cannot be used to open the liftgate.
When the LIFTGATE button on the RKE trans-
mitter is pressed two times, the turn signals will
flash twice to signal that the liftgate is opening
or closing.
NOTE:
In the event of a power malfunction to the
liftgate, an emergency liftgate latch release
can be used to open the liftgate. The emer-
gency liftgate latch release can be accessed
through a snap-in cover located on the lift-
gate trim panel.
WARNING!
During power operation, personal injury or
cargo damage may occur. Ensure the liftgate
travel path is clear. Make sure the liftgate is
closed and latched before driving away.
NOTE:
• 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 suffi-
cient 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 or
overhead console close button to oper-
ate. 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.

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 Seat-Mounted Side Airbag Label

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.

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

pending on the severity and type of collision. In
these events, the ORC will deploy the SABIC
only on the impact side of the vehicle.
A quantity of non-toxic gas is generated to
inflate the side curtain airbag. The inflating side
curtain airbag pushes the outside edge of the
headliner out of the way and covers the win-
dow. The airbag inflates in about 30 ms (about
one-quarter of the time that it takes to blink your
eyes) with enough force to injure you if you are
not belted and seated properly, or if items are
positioned in the area where the side curtain
airbag inflates. This especially applies to chil-
dren. The side curtain airbag is only about
3-1/2 in (9 cm) thick when it is inflated.
Because airbag sensors estimate deceleration
over time, vehicle speed and damage are not
good indicators of whether or not an airbag
should have deployed.
NOTE:
In a rollover the pretensioners, and/or SAB
and SABIC airbags 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 re-
sponse to impact events. Additional sensors in
the ORC determine the level of airbag deploy-
ment and provide verification.
Enhanced Accident Response System
In the event of an impact causing airbag de-
ployment, if the communication network re-
mains 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. If a Deployment Occurs
The Advanced Front Airbags are designed to
deflate immediately after deployment.
NOTE:
Front and/or side airbags will not deploy in
all collisions. This does not mean some-
thing is wrong with the airbag system.
If you do have a collision which deploys the
airbags, any or all of the following may occur:
•
The nylon airbag material may sometimes
cause abrasions and/or skin reddening to
the driver and front passenger as the air-
bags deploy and unfold. The abrasions are
similar to friction rope burns or those you
might get sliding along a carpet or gymna-
sium floor. They are not caused by contact
with chemicals. They are not permanent and
normally heal quickly. However, if you
haven’t healed significantly within a few
days, or if you have any blistering, see your
doctor immediately.

Illuminated Vanity MirrorsTo access an illuminated vanity mirror, flip down
one of the visors.
Lift the cover to reveal the mirror. The light will
turn on automatically.
Sun Visor Extension — If EquippedThis feature has a pull out extension on the sun
visor for increased coverage.
BLIND SPOT MONITORING —
IF EQUIPPED
The Blind Spot Monitoring (BSM) system uses
two radar-based sensors, located inside the
rear bumper fascia, to detect Highway licens-
able vehicles (automobiles, trucks, motor-
cycles etc.) that enter the blind spot zones from
the rear/front/side of the vehicle.
When the vehicle is started, the BSM warning
light will be momentarily illuminated in both
outside rear view mirrors to let the driver know
that the system is operational. The BSM system
sensors operate when the vehicle is in anyforward gear or REVERSE and enters stand by
mode when the vehicle is in PARK.
The BSM detection zone covers approximately
one lane on both sides of the vehicle (11 ft or
3.35 m). The zone starts at the outside rear view
mirror and extends approximately 20 ft (6 m) to
the rear of the vehicle. The BSM system moni-
tors the detection zones on both sides of the
vehicle when the vehicle speed has reached
approximately 6 mph (10 km/h) or higher and
will alert the driver of vehicles in these areas.
NOTE:
•
The BSM system does NOT alert the
driver about rapidly approaching vehicles
that are outside the detection zones.
•
The BSM system detection zone DOES
NOT change if your vehicle is towing a
trailer. Therefore, visually verify the adja-
cent lane is clear for both your vehicle and
trailer before making a lane change. If the
trailer or other object (i.e., bicycle, sports
equipment) extends beyond the side of
your vehicle, this may result in the BSM
warning light remaining illuminated the
entire time the vehicle is in a forward gear.Illuminated Vanity Mirror
Rear Detection Zones
69

The area on the rear fascia where the radar
sensors are located must remain free of snow,
ice, and dirt/road contamination so that the
BSM system can function properly. Do not
block the area of the rear fascia where the radar
sensors are located with foreign objects
(bumper stickers, bicycle racks, etc.).
The BSM system notifies the driver of objects in
the detection zones by illuminating the BSM
warning light located in the outside mirrors.The BSM system can also be configured to
sound an audible (chime) alert and reduce the
radio volume to notify the driver of objects that
have entered the detection zones. Refer to
“Modes Of Operation” for further information.
The BSM system monitors the detection zone
from three different entry points (Side, Rear,
Front) while driving to see if an alert is neces-
sary. The BSM system will issue an alert during
these types of zone entries.Entering From The Side
Vehicles that move into your adjacent lanes
from either side of the vehicle.
Entering From The Rear
Vehicles that come up from behind your vehicle
on either side and enter the rear detection zone
with a relative speed of less than 30 mph
(48 km/h).

The BSM system will not alert you of objects
that are traveling in the opposite direction of the
vehicle in adjacent lanes.WARNING!
The Blind Spot Monitoring system is only an
aid to help detect objects in the blind spot
zones. The BSM system is not designed to
detect pedestrians, bicyclists, or animals.
Even if your vehicle is equipped with the BSM
system, always check your vehicles mirrors,
glance over your shoulder, and use your turn
signal before changing lanes. Failure to do so
can result in serious injury or death.
Rear Cross PathThe Rear Cross Path (RCP) feature is intended
to aid the driver when backing out of parking
spaces where their vision of oncoming vehicles
may be blocked. Proceed slowly and cau-
tiously out of the parking space until the rear
end of the vehicle is exposed. The RCP system
will then have a clear view of the cross traffic
and if an oncoming vehicle is detected, alert
the driver.RCP monitors the rear detection zones on both
sides of the vehicle, for objects that are moving
toward the side of the vehicle with a minimum
speed of approximately 1 to 2 mph (1 km/h to
3 km/h), to objects moving a maximum of
approximately 10 mph (16 km/h), such as in
parking lot situations.
NOTE:
In a parking lot situation, oncoming vehicles
can be obscured by vehicles parked on
either side. If the sensors are blocked by
other structures or vehicles, the system will
not be able to alert the driver.Opposing Traffic
