A repetitive chime will sound while
the falling liftgate detection feature is
operating. Remove any excess weight.
If the liftgate continues to
automatically close after opening, see
your dealer for service before using
the power liftgate.
Interfering with the power liftgate
motion or manually closing the
liftgate too quickly after power
opening may resemble a support strut
failure. This could also activate the
falling liftgate detection feature. Allow
the liftgate to complete its operation
and wait a few seconds before
manually closing the liftgate.
Obstacle Detection Features
If the liftgate encounters an obstacle
during a power open or close cycle,
the liftgate will automatically reverse
direction and move a short distance
away from the obstacle. After
removing the obstruction, the power
liftgate operation can be used again.
If the liftgate encounters multiple
obstacles on the same power cycle,
the power function will deactivate.
After removing the obstructions,manually close the liftgate. This will
allow normal power operation
functions to resume.
If the vehicle is locked while the
liftgate is closing, and an obstacle is
encountered that prevents the liftgate
from completely closing, the horn will
sound as an alert that the liftgate did
not close.
Setting the 3/4 Mode
To change the position the liftgate
stops at when opening:
1. Select MAX or 3/4 mode and power open the liftgate.
2. Stop the liftgate movement at the desired height by pressing any
liftgate button. Manually adjust the
liftgate position if needed.
3. Press and hold
lon the outside
of the liftgate until the turn signals
flash and a beep sounds. This
indicates the setting has been
recorded. The liftgate cannot be set below a
minimum programmable height.
If there is no light flash or sound,
then the height adjustment may be
too low.
Manual Operation
Select OFF to manually operate the
liftgate.
Caution
Attempting to move the liftgate too
quickly and with excessive force
may result in damage to the
vehicle.
Operate the liftgate manually with a
smooth motion and moderate speed.

The Driver Information Center (DIC)
may display one of these messages:
.A message to service the steering
column lock indicates that an issue
has been detected with the column
lock feature and the vehicle should
be serviced.
.A message that the steering column
is locked indicates that the engine
is running, but the steering column
is still locked. It is normal for the
column to be locked during a
remote start, but the column should
unlock after the brake pedal is
pressed and the vehicle is started.
No message will display during a
remote start.
.A message that the steering wheel
must be turned and the vehicle
must be started again indicates that
the column lock mechanism is
bound, the column locking device
was unable to unlock the steering
column, and the vehicle did not
start. If this happens, immediately
turn the steering wheel from side to
side to unbind the column lock.
If this does not unlock the steering
column, turn the vehicle off and
open the driver door to reset thesystem. Then turn the vehicle on
and immediately turn the steering
wheel side to side for about
15 seconds. In some cases, it may
take significant force to unbind the
column.
To keep the steering column from
binding, straighten the front wheels
before turning off the vehicle.
Immobilizer
See Radio Frequency Statement 0406.
Immobilizer Operation
This vehicle has a passive
theft-deterrent system.
The system does not have to be
manually armed or disarmed.
The vehicle is automatically
immobilized when the vehicle is
turned off.
The immobilization system is
disarmed when the ignition is on or in
ACC/ACCESSORY and a valid
transmitter is present in the vehicle.
The security light, in the instrument
cluster, comes on if there is a problem
with arming or disarming the
theft-deterrent system.
The system has one or more RKE
transmitters matched to an
immobilizer control unit in your
vehicle. Only a correctly matched RKE
transmitter will start the vehicle.
If the transmitter is ever damaged,
you may not be able to start your
vehicle.
When trying to start the vehicle, the
security light may come on briefly
when the ignition is turned on.
If the engine does not start and the
security light stays on, there is a
problem with the system. Turn the
ignition off and try again.
If the vehicle will not change ignition
modes (ACC/ACCESSORY, on, off), and

can help tighten the seat belts during
the early stages of a moderate to
severe frontal, near frontal, or rear
crash if the threshold conditions for
pretensioner activation are met. Seat
belt pretensioners can also help
tighten the seat belts in a side crash
or a rollover event.
Pretensioners work only once. If the
pretensioners activate in a crash, the
pretensioners and probably other
parts of the vehicle’s seat belt system
will need to be replaced. SeeReplacing
Seat Belt System Parts after a Crash
0 60.
Do not sit on the outboard seat belt
while entering or exiting the vehicle or
at any time while sitting in the seat.
Sitting on the seat belt can damage
the webbing and hardware.
Rear Seat Belt Comfort Guides
Rear seat belt comfort guides may
provide added seat belt comfort for
older children who have outgrown
booster seats and for some adults.
When installed on a shoulder belt, the
comfort guide positions the shoulder
belt away from the neck and head. The comfort guides for the second row
outboard seating positions of this
vehicle are provided in a package in
the glove box or cargo area.
Instructions are included with the
comfort guides.
Third Row Seating Positions
Comfort guides are available through
your dealer for the third row seating
positions. Instructions are included
with the comfort guides.
Seat Belt Use During
Pregnancy
Seat belts work for everyone,
including pregnant women. Like all
occupants, they are more likely to be
seriously injured if they do not wear
seat belts.
A pregnant woman should wear a
lap-shoulder belt, and the lap portion
should be worn as low as possible,
below the rounding, throughout the
pregnancy.
The best way to protect the fetus is to
protect the mother. When a seat belt
is worn properly, it is more likely that
the fetus will not be hurt in a crash.
For pregnant women, as for anyone,
the key to making seat belts effective
is wearing them properly.
Seat Belt Extender
If the vehicle's seat belt will fasten
around you, you should use it.

SEATS AND RESTRAINTS 65
a rollover or in a severe frontal
impact. Roof-rail airbags are not
designed to inflate in rear impacts.
Both roof-rail airbags will inflate when
either side of the vehicle is struck,
if the sensing system predicts that the
vehicle is about to roll over on its
side, or in a severe frontal impact.
In any particular crash, no one can
say whether an airbag should have
inflated simply because of the vehicle
damage or repair costs.
What Makes an Airbag
Inflate?
In a deployment event, the sensing
system sends an electrical signal
triggering a release of gas from the
inflator. Gas from the inflator fills the
airbag causing the bag to break out of
the cover. The inflator, the airbag, and
related hardware are all part of the
airbag module.
For airbag locations, seeWhere Are the
Airbags? 062.
How Does an Airbag
Restrain?
In moderate to severe frontal or near
frontal collisions, even belted
occupants can contact the steering
wheel or the instrument panel. In
moderate to severe side collisions,
even belted occupants can contact the
inside of the vehicle.
Airbags supplement the protection
provided by seat belts by distributing
the force of the impact more evenly
over the occupant's body.
Rollover capable roof-rail airbags are
designed to help contain the head and
chest of occupants in the outboard
seating positions in the first, second,
and third rows. The rollover capable
roof-rail airbags are designed to help
reduce the risk of full or partial
ejection in rollover events, although
no system can prevent all such
ejections.
But airbags would not help in many
types of collisions, primarily because
the occupant's motion is not toward
those airbags. See When Should an
Airbag Inflate? 064. Airbags should never be regarded as
anything more than a supplement to
seat belts.What Will You See after an
Airbag Inflates?
After frontal, knee, and seat-mounted
side impact airbags inflate, they
quickly deflate, so quickly that some
people may not even realize the
airbags inflated. Roof-rail airbags may
still be at least partially inflated for
some time after they inflate. Some
components of the airbag module may
be hot for several minutes. For
location of the airbags, see
Where Are
the Airbags? 062.
The parts of the airbag that come into
contact with you may be warm, but
not too hot to touch. There may be
some smoke and dust coming from
the vents in the deflated airbags.
Airbag inflation does not prevent the
driver from seeing out of the
windshield or being able to steer the
vehicle, nor does it prevent people
from leaving the vehicle.

{Warning
When an airbag inflates, there may
be dust in the air. This dust could
cause breathing problems for
people with a history of asthma or
other breathing trouble. To avoid
this, everyone in the vehicle should
get out as soon as it is safe to do
so. If you have breathing problems
but cannot get out of the vehicle
after an airbag inflates, then get
fresh air by opening a window or a
door. If you experience breathing
problems following an airbag
deployment, you should seek
medical attention.
The vehicle has a feature that may
automatically unlock the doors, turn
on the interior lamps and hazard
warning flashers, and shut off the fuel
system after the airbags inflate. The
feature may also activate, without
airbag inflation, after an event that
exceeds a predetermined threshold.
After turning the ignition off and then
on again, the fuel system will return
to normal operation; the doors can be locked, the interior lamps can be
turned off, and the hazard warning
flashers can be turned off using the
controls for those features. If any of
these systems are damaged in the
crash they may not operate as normal.
{Warning
A crash severe enough to inflate the
airbags may have also damaged
important functions in the vehicle,
such as the fuel system, brake and
steering systems, etc. Even if the
vehicle appears to be drivable after
a moderate crash, there may be
concealed damage that could make
it difficult to safely operate the
vehicle.
Use caution if you should attempt
to restart the engine after a crash
has occurred.
In many crashes severe enough to
inflate the airbag, windshields are
broken by vehicle deformation.
Additional windshield breakage may
also occur from the front outboard
passenger airbag.
.Airbags are designed to inflate only
once. After an airbag inflates, you
will need some new parts for the
airbag system. If you do not get
them, the airbag system will not be
there to help protect you in another
crash. A new system will include
airbag modules and possibly other
parts. The service manual for the
vehicle covers the need to replace
other parts.
.The vehicle has a crash sensing and
diagnostic module which records
information after a crash. See
Vehicle Data Recording and Privacy
0 408 and
Event Data Recorders 0408.
.Let only qualified technicians work
on the airbag system. Improper
service can mean that an airbag
system will not work properly. See
your dealer for service.
Passenger Sensing System
The vehicle has a passenger sensing
system for the front outboard
passenger position. The passenger
airbag status indicator will light on
the overhead console when the vehicle
is started.
