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

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.
28

•If your liftgate is power closing and you
put the vehicle in gear, the liftgate will
continue to power close. However, ve-
hicle 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.
• If you are required to drive with the liftgate
open, make sure that all windows are
closed, and the climate control blower
switch is set at high speed. Do not use the
recirculation mode.
Gas props support the liftgate in the open
position. However, because the gas pressure
drops with temperature, it may be necessary to
assist the props when opening the liftgate in
cold weather.
OCCUPANT RESTRAINTSSome of the most important safety features in
your vehicle are the restraint systems:
• Three-point lap and shoulder belts for the
driver and all passengers
• Advanced Front Air Bags for driver and front
passenger
• Supplemental Active Head Restraints (AHR)
located on top of the front seats (integrated
into the head restraint)
• Supplemental Driver Side Knee Air Bag
• Supplemental Side Air Bag Inflatable Cur-
tains (SABIC) for the driver and passengers
seated next to a window
• Supplemental Seat-Mounted Side Air Bags
(SAB)
• An energy-absorbing steering column and
steering wheel
• Knee bolsters/blockers for front seat occu-
pant •
Front seat belts incorporate pretensioners
that may enhance occupant protection by
managing occupant energy during an im-
pact event
• All seat belt systems (except the driver’s and
front passenger) include Automatic Locking
Retractors (ALRs), which lock the seat belt
webbing into position by extending the belt
all the way out and then adjusting the belt to
the desired length to restrain a child seat or
secure a large item in a seat — if equipped
If you will be carrying children too small for
adult-sized seat belts, the seat belts or the
ISOFIX feature also can be used to hold infant
and child restraint systems. Refer to ISOFIX —
Child Seat Anchorage System for more infor-
mation.
NOTE:
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.
Please pay close attention to the information in
this section. It tells you how to use your restraint
29

system properly, to keep you and your passen-
gers as safe as possible.
WARNING!
In an accident, you and your passengers can
suffer much greater injuries if you are not
properly buckled up. You can strike the interior
of your vehicle or other passengers, or you
can be thrown out of the vehicle. Always be
sure you and others in your vehicle are buck-
led up properly.
Buckle up even though you are an excellent
driver, even on short trips. Someone on the
road may be a poor driver and cause an
accident that includes you. This can happen far
away from home or on your own street.
Research has shown that seat belts save lives,
and they can reduce the seriousness of injuries
in an accident. Some of the worst injuries
happen when people are thrown from the ve-
hicle. Seat belts reduce the possibility of ejec-
tion and the risk of injury caused by striking the
inside of the vehicle. Everyone in a motor
vehicle should be belted at all times.
Lap/Shoulder BeltsAll seating positions in your vehicle are
equipped with lap/shoulder belts. The belt
webbing retractor is designed to lock during
very sudden stops or accidents. This feature
allows the shoulder part of the belt to move
freely with you under normal conditions. How-
ever, in an accident the belt will lock and
reduce the risk of you striking the inside of the
vehicle or being thrown out.
WARNING!
•Wearing a seat belt incorrectly is dangerous.
Seat belts are designed to go around the
large bones of your body. These are the
strongest parts of your body and can take the
forces of an accident the best. Wearing your
belt in the wrong place could make your
injuries in an accident much worse. You
might suffer internal injuries, or you could
even slide out of part of the belt. Follow these
instructions to wear your seat belt safely and
to keep your passengers safe, too.
(Continued)
WARNING! (Continued)
• Two people should never be belted into a
single seat belt. People belted together can
crash into one another in an accident,
hurting one another badly. Never use a
lap/shoulder belt or a lap belt for more than
one person, no matter what their size.
• It is dangerous to ride in a cargo area,
inside or outside of a vehicle. In an acci-
dent, people riding in these areas are more
likely to be seriously injured or killed.
• Do not allow people to ride in any area of
your vehicle that is not equipped with seats
and seat belts.
• Be sure everyone in your vehicle is in a
seat and using a seat belt properly.

Lap/Shoulder Belt Operating
Instructions
1. Enter the vehicle and close the door. Sit
back and adjust the seat.
2. The seat belt latch plate is above the back of
your seat. Grasp the latch plate and pull out the
belt. Slide the latch plate up the webbing as far
as necessary to make the belt go around your
lap.
3. When the belt is long enough to fit, insert the
latch plate into the buckle until you hear a
“click.”
WARNING!
•A belt that is buckled into the wrong buckle
will not protect you properly. The lap portion
could ride too high on your body, possibly
causing internal injuries. Always buckle
your belt into the buckle nearest you.
• A belt that is too loose will not protect you
properly. In a sudden stop you could move
too far forward, increasing the possibility of
injury. Wear your seat belt snugly.
(Continued)
WARNING!(Continued)
• A belt that is worn under your arm is
dangerous. Your body could strike the in-
side surfaces of the vehicle in an accident,
increasing head and neck injury. A belt
worn under the arm can cause internal
injuries. Ribs aren’t as strong as shoulder
bones. Wear the belt over your shoulder so
that your strongest bones will take the force
in a collision.
• A shoulder belt placed behind you will not
protect you from injury during an accident.
You are more likely to hit your head in a
collision if you do not wear your shoulder
belt. The lap and shoulder belt are meant to
be used together.
4. Position the lap belt across your thighs,
below your abdomen. To remove slack in the
lap portion, pull up a bit on the shoulder belt. To
loosen the lap belt if it is too tight, tilt the latch
plate and pull on the lap belt. A snug belt
reduces the risk of sliding under the belt in an
accident.

WARNING!
•A lap belt worn too high can increase the
risk of injury in an accident. The belt forces
won’t be at the strong hip and pelvic bones,
but across your abdomen. Always wear the
lap part of your seat belt as low as possible
and keep it snug.
• A twisted belt will not protect you properly.
In a collision, it could even cut into you. Be
sure the belt is straight. If you can’t
straighten a belt in your vehicle, take it to
your authorized dealer immediately and
have it fixed.
5. Position the shoulder belt on your chest so
that it is comfortable and not resting on your
neck. The retractor will withdraw any slack in
the belt. 6. To release the belt, push the red button on
the buckle. The belt will automatically retract to
its stowed position. If necessary, slide the latch
plate down the webbing to allow it to retract
fully.WARNING!
A frayed or torn belt could rip apart in an
accident and leave you with no protection.
Inspect the belt system periodically, checking
for cuts, frays, or loose parts. Damaged parts
must be replaced immediately. Do not disas-
semble or modify the system. Seat belt as-
semblies must be replaced after an accident if
they have been damaged (bent retractor, torn
webbing, etc.).
Lap/Shoulder Belt Untwisting
Procedure
Use the following procedure to untwist a
twisted lap/shoulder belt.
1. Position the latch plate as close as possible
to the anchor point.
2. At about 6 to 12 in (15 to 30 cm) above the
latch plate, grasp and twist the belt webbing
180 degrees to create a fold that begins imme-
diately above the latch plate.
Removing Slack From Belt
32

3. Slide the latch plate upward over the folded
webbing. The folded webbing must enter the
slot at the top of the latch plate.
4. Continue to slide the latch plate up until it
clears the folded webbing.
Adjustable Upper Shoulder Belt
Anchorage
In the front seating positions, the shoulder belt
can be adjusted upward or downward to posi-
tion the belt away from your neck. Press the
release button to release the anchorage, and
then move it up or down to the position that
serves you best.As a guide, if you are shorter than average, you
will prefer a lower position, and if you are taller
than average, you will prefer a higher position.
When you release the button, verify the shoul-
der belt anchorage is latched by pulling down-
ward on the shoulder belt anchorage until it is
locked into position.
NOTE:
The adjustable upper shoulder belt anchor-
age is equipped with an Easy Up feature.
This feature allows the shoulder belt an-
chorage to be adjusted in the upward posi-
tion without pressing the release button. To
verify the shoulder belt anchorage is
latched, pull downward on the shoulder belt
anchorage until it is locked into position.
In the rear seat, move toward the center of the
seat to position the belt away from your neck.
Seat Belts In Passenger Seating
Positions
The seat belts in the passenger seating posi-
tions are equipped with Automatic Locking
Retractors (ALR) which are used to secure a
child restraint system. For additional informa-
tion, refer to “Installing Child Restraints UsingThe Vehicle Seat Belt” under the “Child Re-
straints” section. The chart below defines the
type of feature for each seating position.
Driver Center Passen-
ger
First Row N/A N/A N/A Second Row ALR ALR ALR
Third Row N/A N/A N/A
• N/A — Not Applicable
• ALR — Automatic Locking Retractor
If the passenger seating position is equipped
with an ALR and is being used for normal
usage:
Only pull the belt webbing out far enough to
comfortably wrap around the occupant’s mid-
section so as to not activate the ALR. If the ALR
is activated, you will hear a ratcheting sound as
the belt retracts. Allow the webbing to retract
completely in this case and then carefully pull
out only the amount of webbing necessary to
comfortably wrap around the occupant’s mid-
section. Slide the latch plate into the buckle
until you hear a click.

Automatic Locking Retractor Mode
(ALR) — If Equipped
In this mode, the shoulder belt is automatically
pre-locked. The belt will still retract to remove
any slack in the shoulder belt. The Automatic
Locking Mode is available on all rear
passenger-seating positions with a combina-
tion lap/shoulder belt. Use the Automatic Lock-
ing Mode anytime a child safety seat is installed
in a seating position that has a belt with this
feature. Children 12 years old and under
should always be properly restrained in the rear
seat.
How To Engage The Automatic Locking
Mode
1. Buckle the combination lap and shoulder
belt.
2. Grasp the shoulder portion and pull down-
ward until the entire belt is extracted.
3. Allow the belt to retract. As the belt retracts,
you will hear a clicking sound. This indicates
the safety belt is now in the Automatic Locking
Mode.How To Disengage The Automatic Locking
Mode
Unbuckle the combination lap/shoulder belt
and allow it to retract completely to disengage
the Automatic Locking Mode and activate the
vehicle sensitive (emergency) locking mode.
WARNING!
•
The belt and retractor assembly must be
replaced if the seat belt assembly Auto-
matic Locking Retractor (ALR) feature or
any other seat belt function is not working
properly when checked according to the
procedures in the Service Manual.
• Failure to replace the belt and retractor
assembly could increase the risk of injury in
collisions.
Energy Management FeatureThis vehicle has a safety belt system with an
Energy Management feature in the front seating
positions to help further reduce the risk of injury
in the event of a head-on accident. This safety belt system has a retractor assem-
bly that is designed to release webbing in a
controlled manner. This feature is designed to
help reduce the belt force acting on the occu-
pant’s chest.
Seat Belt PretensionersThe seat belts for both front seating positions
are equipped with pretensioning devices that
are designed to remove slack from the seat belt
in the event of an accident. These devices may
improve the performance of the seat belt by
assuring that the belt is tight about the occu-
pant early in an accident. Pretensioners work
for all size occupants, including those in child
restraints.
NOTE:
These devices are not a substitute for
proper seat belt placement by the occupant.
The seat belt still must be worn snugly and
positioned properly.
The pretensioners are triggered by the Occu-
pant Restraint Controller (ORC). Like the air
bags, the pretensioners are single use items. A
deployed pretensioner or a deployed air bag
must be replaced immediately.

Supplemental Active Head
Restraints (AHR)
These head restraints are passive, deployable
components, and vehicles with this equipment
cannot be readily identified by any markings,
only through visual inspection of the head re-
straint. 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) de-
termines whether the severity, or type of rear
impact will require the Active Head Restraints
(AHR) to deploy. If a rear impact requires
deployment, both the driver and front passen-
ger 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 severity and type of the
impact.
CAUTION!
All occupants, including the driver, should not
operate 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 an accident.
NOTE:
For more information on properly adjusting
and positioning the head restraint, refer to
“Adjusting Active Head Restraints” in “Un-
derstanding The Features Of Your Vehicle”.
Resetting Active Head Restraints (AHR)
If the Active Head Restraints are triggered in an
accident, you must reset the head restraint on
the driver’s and front passenger seat. 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).
