Power Liftgate Operation
{Warning
You, or others, could be injured if
caught in the path of the power
liftgate. Make sure there is no one
in the way of the liftgate as it is
opening and closing.
If equipped with a power liftgate, the
switch is on the overhead console.
The vehicle must be in P (Park).There are three modes:
.MAX: The liftgate power opens
to the maximum height.
.3/4: The liftgate power opens to
a reduced height that can be set
from 3/4 to fully open. Use this
setting to prevent the liftgate
from opening into overhead
obstructions such as a garage
door or roof-mounted cargo
during power operation. The
liftgate can still be manually
opened all the way.
.OFF: The liftgate only operates
manually in this position.
To power open or close the liftgate,
select MAX or 3/4 mode.
.Pressbtwice quickly on the
RKE transmitter until the liftgate
moves.
.Press8on the overhead
console. The driver door must
also be unlocked.
.Press the touch pad on the
outside liftgate handle after
unlocking all doors. If equipped
with Keyless Access a locked
vehicle can be opened if the
RKE transmitter is within 1m
(3 ft.) of the touch pad.
.Presslon the bottom edge of
the liftgate next to the latch to
close.
Press any liftgate button or the
touch pad or

restarts the operation in the reverse
direction. The touch pad on the
liftgate handle cannot be used to
close the liftgate.
Do not manually force the liftgate to
open or close during a power cycle.
The power liftgate may be
temporarily disabled in extremely
low temperatures, or after repeated
power cycling over a short period of
time. If this occurs, the liftgate can
still be operated manually. Select
OFF on the liftgate switch.
If the vehicle is shifted out of
P (Park) while the power function is
in progress, the liftgate will continue
to completion. If the vehicle is
accelerated before the liftgate has
completed moving, the liftgate may
stop or reverse direction. Make sure
the liftgate is closed and latched
before driving.
If the power liftgate support strut
has lost pressure, the turn signals
will flash and a chime will soundwhile the liftgate automatically
closes. See your dealer for service
before using the power liftgate.
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, which
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.
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 reverse
direction 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
power open the liftgate.
2. Stop the liftgate movement at the desired height by pressing
any liftgate switch. Manually
adjust the liftgate position if
needed.
3. Press and hold
8next 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.

Keys, Doors, and Windows 2-21
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 opened
via a kicking motion beneath the
rear bumper.
If the RKE transmitter is not within
1m (3 ft) of the liftgate during
hands-free operation, the liftgate will
not open.
To operate the hands-free system:
1. Under the center of the rearbumper, kick your foot up in one
swift motion and then pull
it back.
2. Do not touch the liftgate until it has fully opened.
Keep the RKE transmitter away
from the rear of the vehicle or turn

3-2 Seats and Restraints
Head Restraints
Front Seats
The vehicle’s front seats have
adjustable head restraints in the
outboard seating positions.
{Warning
With head restraints that are not
installed and adjusted properly,
there is a greater chance that
occupants will suffer a neck/
spinal injury in a crash. Do not
drive until the head restraints for
all occupants are installed and
adjusted properly.
Adjust the head restraint so that the
top of the restraint is at the same
height as the top of the occupant's
head. This position reduces the
chance of a neck injury in a crash.The height of the head restraint can
be adjusted. Pull the head restraint
up to raise it. Try to move the head
restraint to make sure that it is
locked in place.
To lower the head restraint, press
the button, located on the top of the
seatback, and push the head
restraint down. Try to move the
head restraint after the button is
released to make sure that it is
locked in place.
The front seat outboard head
restraints are not removable.

are using the correct buckle.
Pull up on the latch plate to
make sure it is secure. If the belt
is not long enough, see Safety
Belt Extender on page 3-27.
Position the release button on
the buckle so that the safety belt
could be quickly unbuckled if
necessary.
4. If equipped with a shoulder belt height adjuster, move it to the
height that is right for you. See
“Shoulder Belt Height Adjuster”
in this section for instructions on
use and important safety
information.
5. To make the lap part tight, pullup on the shoulder belt.
For third row seats, it may be
necessary to pull stitching on the
safety belt through the latch

guide loop on the side wall.
Before a door is closed, be sure the
safety belt is out of the way. If a
door is slammed against a safety
belt, damage can occur to both the
belt and the vehicle.
Shoulder Belt Height Adjuster
The vehicle has a shoulder belt
height adjuster for the driver and
front outboard passenger positions.
Adjust the height so the shoulder
portion of the belt is on the shoulder
and not falling off of it. The belt
should be close to, but not
contacting, the neck. Improper
shoulder belt height adjustment
could reduce the effectiveness of
the safety belt in a crash. SeeHow
to Wear Safety Belts Properly on
page 3-20.
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.

3-40 Seats and Restraints
{Warning
Stowing of articles under the
passenger seat or between the
passenger seat cushion and
seatback may interfere with the
proper operation of the passenger
sensing system.
Servicing the
Airbag-Equipped Vehicle
Airbags affect how the vehicle
should be serviced. There are parts
of the airbag system in several
places around the vehicle. Your
dealer and the service manual have
information about servicing the
vehicle and the airbag system. To
purchase a service manual, see
Service Publications Ordering
Information on page 13-11.
{Warning
For up to 10 seconds after the
vehicle is turned off and the
battery is disconnected, an airbag
can still inflate during improper
service. You can be injured if you
are close to an airbag when it
inflates. Avoid yellow connectors.
They are probably part of the
airbag system. Be sure to follow
proper service procedures, and
make sure the person performing
work for you is qualified to do so.
Adding Equipment to the
Airbag-Equipped Vehicle
Adding accessories that change the
vehicle's frame, bumper system,
height, front end, or side sheet
metal may keep the airbag system
from working properly.
The operation of the airbag system
can also be affected by changing
any parts of the front seats, safetybelts, airbag sensing and diagnostic
module, steering wheel, instrument
panel, any airbag module, ceiling or
pillar garnish trim, overhead
console, front sensors, side impact
sensors, airbag wiring, or front
center console.
Your dealer and the service manual
have information about the location
of the airbag sensors, sensing and
diagnostic module, and airbag
wiring.
In addition, the vehicle has a
passenger sensing system that
includes sensors as part of the front
outboard passenger seat. The
passenger sensing system may not
operate properly if the original seat
trim is replaced with non-GM
covers, upholstery, or trim; or with
GM covers, upholstery, or trim
designed for a different vehicle. Any
object, such as an aftermarket seat
heater or a comfort-enhancing pad
or device, installed under or on top
of the seat fabric, could also
interfere with the operation of the
passenger sensing system. This
