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.
Caution
Driving with an open and
unsecured liftgate may result in
damage to the power liftgate
components.
If equipped with a power liftgate, the
switch is on the driver door. The
vehicle must be in P (Park).
The modes are:
. MAX: Opens to maximum
height.
. 3/4: Opens to a reduced height
that can be set from 3/4 to fully
open. Use to prevent the liftgate
from opening into overhead

.Presslon the bottom of the
liftgate next to the pull cup to
close.
Press any liftgate button or the
touch pad while the liftgate is
moving to stop it. Pressing again
restarts the operation in the reverse
direction. The touch pad on the
liftgate handle cannot be used to
close the liftgate.
Caution
Manually forcing the liftgate to
open or close during a power
cycle can damage the vehicle.
Allow the power cycle to
complete.
The power liftgate may be
temporarily disabled under extreme
low temperatures, or after repeated
power cycling over a short period of
time. If this occurs, the liftgate can
still be operated manually.
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. Check for
DIC messages and make sure the
liftgate is closed and latched before
driving.
Falling Liftgate Detection
The power liftgate will automatically
close if the support strut has lost
pressure. 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,
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 this
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.

smooth motion and moderate
speed. The system includes a
feature which limits the manual
closing speed to protect the
components.

operated with a kicking motion
under the left corner of the rear
bumper.

The vehicle's front seats have
adjustable head restraints in the
outboard seating positions.
Adjust the head restraint so that the

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, safety
belts, airbag sensing and diagnostic
module, steering wheel, instrument
panel, any of the airbag modules,
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 for the
front outboard passenger position,
which includes sensors that are part
of the passenger's 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
could either prevent proper
deployment of the passenger
airbag(s) or prevent the passenger
sensing system from properly
turning off the passenger airbag(s).
See
Passenger Sensing
System 081. If the vehicle has rollover roof-rail
airbags, see
Different Size Tires
and Wheels 0332 for additional
important information.
If you have to modify your vehicle
because you have a disability and
you have questions about whether
the modifications will affect the
vehicle's airbag system, or if you
have questions about whether the
airbag system will be affected if the
vehicle is modified for any other
reason, call Customer Assistance.
See Customer Assistance
Offices 0386.
Airbag System Check
The airbag system does not need
regularly scheduled maintenance or
replacement. Make sure the airbag
readiness light is working. See
Airbag Readiness Light 0131.
Caution
If an airbag covering is damaged,
opened, or broken, the airbag
may not work properly. Do not
