Obstacle Detection Features
If the liftgate encounters an obstacle
during a power open or close cycle,
a warning chime will sound and 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
prevents the liftgate from completely
closing, the horn will sound as an
alert that the liftgate did not close.
Pinch sensors are on the side
edges of the liftgate. If an object is
caught between the liftgate and the
vehicle and presses against a
sensor, the liftgate will reversedirection and open fully. The liftgate
will remain open until it is activated
again or closed manually.
Setting the 3/4 Mode
To change the position the liftgate
stops at when opening:
1. Select MAX or 3/4 mode and
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
lnext to the
latch on 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. See “Manual Liftgate” at the
beginning of this section.
Hands-Free Operation
If equipped with Hands-Free Vehicle
Access, the liftgate may be
operated with a kicking motion
under the rear bumper.
The liftgate will not operate if the
RKE transmitter is not within
1 m (3 ft).
The hands-free feature will not work
while the liftgate is moving. To stop
the liftgate while in motion use one
of the liftgate switches.

transmitter away from the rear
bumper detection area or turn the
liftgate mode to OFF when
cleaning or working near the rear
bumper to avoid accidental
opening.
.Do not sweep your foot side
to side.
.Do not keep your foot under the
bumper; the liftgate will not

The vehicle aerodynamics are
designed to improve fuel economy
performance. This may result in a
pulsing sound when either rear
window is down and the front
windows are up. To reduce the
sound, open either a front window
or the sunroof, if equipped.
Power Windows
{Warning
Children could be seriously
injured or killed if caught in the
path of a closing window. Never
leave keys in a vehicle with
children. When there are children
in the rear seat, use the window
lockout button to prevent
operation of the windows. See
Keys (Key) on page 2-2orKeys
(Keyless) on page 2-4.The driver door has switches that
control all windows. Each
passenger door switch only controls
that window. The power windows
work when the ignition is in ON/

Express Window Anti-Pinch
Feature
If any object is in the path of the
window when express-up is active,
the window stops at the obstacle
and auto-reverses to a preset
factory position. Weather conditions
such as severe icing also cause the
window to auto-reverse. The window returns to normal operation
once the obstacle or condition is
removed.
Express Window Anti-Pinch
Override
{Warning
If express override is activated,
the window will not reverse
automatically. You or others could
be injured and the window could
be damaged. Before you use
express override, make sure that
all people and obstructions are
clear of the window path.
The anti-pinch feature can be
overridden in a supervised mode.
Hold the window switch in the
partially or fully pulled up position.
The window rises for as long as the
switch is held. Once the switch is
released, the express mode is
reactivated. In this mode, the window can still
close on an object in its path. Use
care when using the override mode.

Push down on the release button to
move the height adjuster to the
desired position.
Move the adjuster up by pushing up
on the shoulder belt guide.
After the adjuster is set to the
desired position, try to move it down
without pushing the release button
to make sure it has locked into
position.
Safety Belt Pretensioners
This vehicle has safety belt
pretensioners for front outboard
occupants. Although the safety belt
pretensioners cannot be seen, they
are part of the safety belt assembly.
They can help tighten the safety
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. Safety belt
pretensioners can also help tighten
the safety 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 safety
belt system will need to be replaced.
See
Replacing Safety Belt System
Parts after a Crash on page 3-29.
Rear Safety Belt Comfort
Guides
{Warning
A safety belt that is not properly
worn may not provide the
protection needed in a crash. The
person wearing the belt could be
seriously injured. The shoulder
belt should go over the shoulder
and across the chest. These parts
of the body are best able to take
belt restraining forces.
Rear safety belt comfort guides may
provide added safety 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.
Rear Outboard Seating Positions
There are comfort guides for the
rear outboard seating positions for
the second row and the third row
outboard seating positions. The
comfort guides are stored on a clip
on the interior trim next to the
outboard seatback.
To install:

Seats and Restraints 3-35
roof-rail airbags are designed to
inflate during 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 the 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? on page 3-32.
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 safety belts by
distributing the force of the impact
more evenly over the
occupant's body.
Rollover capable roof-rail airbags
are also 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? on
page 3-34 for more information.
Airbags should never be regarded
as anything more than a supplement
to safety belts.
What Will You See after
an Airbag Inflates?
After the frontal airbags and
seat-mounted side impact airbags
inflate, they quickly deflate, so
quickly that some people may not
even realize an airbag inflated. The
front center airbag, if equipped, and
the 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? on page 3-32.
