rear trim once will close the liftgate only, this
button cannot be used to open the liftgate.
To operate the power liftgate manually in the
open direction, pull the liftgate handle once to
initiate a power cycle and then pull the handle
a second time to put liftgate into manual mode.
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 (if Flash Lamps with Lock is enabled
in the EVIC) and the liftgate chime will be
audible. For further information, refer to
Customer-Programmable Features (System
Setup)/Electronic Vehicle Information Center
(EVIC)inUnderstanding Your Instrument
Panel.
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:
• The power liftgate will not operate if the
liftgate flipper glass is open.
• The power liftgate buttons will not oper-
ate if the vehicle is in gear or the vehicle
speed is above 0 mph (0 km/h).
• The power liftgate will not operate in tem-
peratures below 22°F (30°C) or tem-
peratures 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 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 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 mo-
tor will disengage to allow manual opera-
tion.
• 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.

glove compartment. The words SRS AIRBAG
are embossed on the air bag covers. In addi-
tion, the vehicle is equipped with a Supplemen-
tal Driver Side Knee Air Bag mounted in the
instrument panel below the steering column.
The Advanced Front Air Bags have a multi-
stage inflator design. This allows the air bag to
have different rates of inflation based on the
severity and type of collision.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 accident, the vehicle should be
taken to an authorized dealer immedi-
ately.

NOTE:
•Should a vehicle rollover occur, the pre-
tensioners and/or SAB and SABIC air
bags on both sides of the vehicle may
deploy.
• 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.
The system includes side impact sensors that
are calibrated to deploy the side air bags
during impacts that require air bag occupant
protection.WARNING!
• Your vehicle is equipped with left and right
Supplemental Side Air Bag 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 air bags;
the performance could be adversely af-
fected 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 permanent at-
tachments (bolts or screws) for installation
on the vehicle roof. Do not drill into the roof
of the vehicle for any reason. Supplemental Driver Side Knee Air Bag
The Supplemental Driver Side Knee Air Bag
provides enhanced protection and works to-
gether with the Driver Advanced Front Air Bag
during a frontal impact.
Knee Impact Bolster
The Knee Impact Bolster helps protect the
knees of the front passenger, and position the
front occupant for the best interaction with the
Advanced Front Air Bag.
Along with seat belts and pretensioners, Ad-
vanced Front Air Bags work with the Supple-
mental Driver Side Knee Air Bag and the pas-
senger side knee bolster to provide improved
protection for the front passenger. Side air bags
also work with seat belts to improve occupant
protection.
Here are some simple steps you can take to
minimize the risk of harm from a deploying air
bag:
Children 12 years old and under should always
ride buckled up in a rear seat.
40

WARNING!
Infants in rear-facing child restraints should
never ride in the front seat of a vehicle with a
passenger Advanced Front Air Bag. An air bag
deployment can cause severe injury or death
to infants in that position.
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.
You should read the instructions provided with
your child restraint to make sure that you are
using it properly.
All occupants should always wear their lap and
shoulder belts properly.
The driver and front passenger seats should be
moved back as far as practical to allow the
Advanced Front Air Bags room to inflate. Do not lean against the door or window. If your
vehicle has side air bags, and deployment
occurs, the side air bags will inflate forcefully
into the space between you and the door.
If the air bag 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 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, the air
bags won’t deploy at all. Always wear your
seat belts even though you have air bags.
• 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.
(Continued)
WARNING!(Continued)
• The Supplemental Side Air Bag Inflatable
Curtain (SABIC) and Supplemental Seat-
Mounted Side Air Bag (SAB) also need
room to inflate. Do not lean against the
door or window. Sit upright in the center of
the seat.
• Being too close to the Supplemental Side
Air Bag Inflatable Curtain (SABIC) and/or
Seat-Mounted Side Air Bag (SAB) during
deployment could cause you to be severely
injured or killed.
Air Bag 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 air bags in a frontal or side collision
is required. Based on the impact sensor’s sig-
nals, a central electronic ORC deploys the
Advanced Front Air Bags, Supplemental Driver
Side Knee Air Bag, Supplemental Side Air Bag
41

Inflatable Curtain (SABIC), Supplemental Seat-
Mounted Side Air Bags (SAB), and front seat
belt pretensioners, as required, depending on
the severity and type of impact.
Advanced Front Air Bags and Supplemental
Driver Side Knee Air Bag are designed to
provide additional protection by supplementing
the seat belts in certain frontal collisions de-
pending on the severity and type of collision.
Advanced Front Air Bags are not expected to
reduce the risk of injury in rear, or side colli-
sions.
The Advanced Front Air Bags and Supplemen-
tal Driver Side Knee Air Bag will not deploy in all
frontal collisions, including some that may pro-
duce substantial vehicle damage — for ex-
ample, 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.Because air bag sensors measure vehicle de-
celeration over time, vehicle speed and dam-
age by themselves are not good indicators of
whether or not an air bag 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 air bag.
The ORC monitors the readiness of the elec-
tronic parts of the air bag 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 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 discon-
nected prior to deployment.
Also, the ORC turns on the Air Bag
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 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 instrument cluster Air Bag Warning Light if a
malfunction is noted that could affect the air
bag system. The diagnostics also record the
nature of the malfunction.
WARNING!
Ignoring the Air Bag Warning Light in your
instrument panel could mean you won’t have
the air bags to protect you in a collision. If the
light does not come on as a bulb check when
the ignition is first turned on, stays on after
you start the vehicle, or if it comes on as you
drive, have an authorized dealer service the
air bag system immediately.

especially applies to children. The side curtain
air bag 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 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.
Enhanced Accident Response System
In the event of an impact causing air bag
deployment, 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 Air Bags are designed to
deflate immediately after deployment.
NOTE:
Front and/or side air bags will not deploy in
all collisions. This does not mean some-
thing is wrong with the air bag system.
If you do have a collision which deploys the air
bags, any or all of the following may occur:
• The nylon air bag 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.
• As the air bags deflate, you may see some
smoke-like particles. The particles are a nor-
mal by-product of the process that gener-
ates the non-toxic gas used for air bag
inflation. These airborne particles may irri-
tate the skin, eyes, nose, or throat. If you
have skin or eye irritation, rinse the area with
cool water. For nose or throat irritation, move
to fresh air. If the irritation continues, see your
doctor. If these particles settle on your cloth-
ing, follow the garment manufacturer’s in-
structions for cleaning.
Do not drive your vehicle after the air bags have
deployed. If you are involved in another colli-
sion, the air bags will not be in place to protect
you.

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 momentarily illuminate in both outside
rear view mirrors to let the driver know that the
system is operational. The BSM system sen-
sors operate when the vehicle is in any forwardgear 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
Illuminated Vanity Mirror
Rear Detection Zones
69

BSM warning light remaining illuminated
the entire time the vehicle is in a forward
gear.
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 (bum-
per 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 in
addition to sounding an audible (chime) alert
and reducing the radio volume. 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).
