the vehicle. SeeRoadside Assistance Program
0 343. With an active OnStar or connected service
plan, an OnStar Advisor may remotely
unlock the vehicle. See
OnStar Overview
0 352.
Remote Key
See Radio Frequency Statement 0348.
If there is a decrease in the remote key
operating range:
.Check the distance. The remote key may
be too far from the vehicle.
.Check the location. Other vehicles or
objects may be blocking the signal.
.Check the remote key's battery. See
“Battery Replacement” later in this
section.
.If the remote key is still not working
correctly, see your dealer or a qualified

Remote Key Operation
The Keyless Access system allows for vehicle
entry when the remote key is within 1 m
(3 ft). See “Keyless Access Operation”
following.
The remote key functions may work up to
60 m (197 ft) away from the vehicle. Other conditions can impact the
performance of the remote key. See
Remote
Key 08.

failure. 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
lnext to the pull cup
on the bottom 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
system includes a feature which limits the
manual closing speed to protect the
components.
Hands-Free Operation
If equipped, the liftgate may be operated
with a kicking motion under the left corner
of the rear bumper at the location of the
projected logo.
The remote key must be within 1 m (3 ft) of
the rear bumper to operate the power
liftgate hands-free.
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.

How to Detect a Tamper Condition
IfIis pressed and the horn chirps and the
lights flash three times, the alarm was
activated while the alarm system was
armed.
If the alarm system has been activated, a
message will appear on the DIC.
Immobilizer
See Radio Frequency Statement 0348.
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 accessory
mode and a valid remote key 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 remote keys
matched to an immobilizer control unit in
your vehicle. Only a correctly matched
remote key will start the vehicle. If the
remote key 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
(accessory mode, on, off), and the remote
key appears to be undamaged, try another
remote key. Or, you may try placing the
remote key in the front cupholder located in
the center console. See Remote Key
Operation 08. If the ignition mode will not change with
the other remote key or in the front
cupholder, your vehicle needs service. If the
ignition does change modes, the first
remote key may be faulty. See your dealer
who can service the theft-deterrent system
and have a new remote key programmed to
the vehicle.
It is possible for the immobilizer system to
learn new or replacement remote keys. Up
to eight remote keys can be programmed
for the vehicle. To program additional
remote keys, see
“Programming Remote
Keys to the Vehicle” underRemote Key
Operation 08.
Do not leave the key or device that disarms
or deactivates the theft-deterrent system in
the vehicle.

{Warning
The Rear Camera Mirror (RCM) has a
limited view. Portions of the road,
vehicles, and other objects may not be
seen. Do not drive or park the vehicle
using only this camera. Objects may
appear closer than they are. Check the
outside mirrors or glance over your
shoulder when making lane changes or

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. SeeVehicle
Data Recording and Privacy 0349 and
Event Data Recorders 0350.
.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.
The words ON and OFF, and the symbols for
on and off, will be visible during the system
check. When the system check is complete,
either the word ON or OFF, and the symbol
for on or off, will be visible. See Passenger
Airbag Status Indicator 0101.
The passenger sensing system turns off the
front outboard passenger frontal airbag and
knee airbag under certain conditions. No
other airbag is affected by the passenger
sensing system.
The passenger sensing system works with
sensors that are part of the front outboard
passenger seat and seat belt. The sensors
are designed to detect the presence of a
properly seated occupant and determine if
the front outboard passenger frontal airbag
and knee airbag should be allowed to inflate
or not.
According to accident statistics, children are
safer when properly secured in a rear seat
in the correct child restraint for their weight
and size.
Whenever possible, children aged 12 and
under should be secured in a rear seating
position. Never put a rear-facing child seat in the
front. This is because the risk to the
rear-facing child is so great, if the airbag
inflates.
{Warning
A child in a rear-facing child restraint can
be seriously injured or killed if the
passenger frontal airbag inflates. This is
because the back of the rear-facing child
restraint would be very close to the
inflating airbag. A child in a
forward-facing child restraint can be
seriously injured or killed if the passenger
frontal airbag inflates and the passenger
seat is in a forward position.
Even if the passenger sensing system has
turned off the front outboard passenger
airbag(s), no system is fail-safe. No one
can guarantee that an airbag will not
deploy under some unusual circumstance,
even though the airbag(s) are off.
Never put a rear-facing child restraint in
the front seat, even if the airbag is off.
If securing a forward-facing child restraint
in the front outboard passenger seat,
always move the seat as far back as it

Warning (Continued)
will go. It is better to secure child
restraints in the rear seat. Consider using
another vehicle to transport the child
when a rear seat is not available.
The passenger sensing system is designed to
turn off the front outboard passenger
frontal airbag and knee airbag if:
.The front outboard passenger seat is
unoccupied.
.The system determines an infant is
present in a child restraint.
.A front outboard passenger takes his/her
weight off of the seat for a period
of time.
.There is a critical problem with the airbag
system or the passenger sensing system.
When the passenger sensing system has
turned off the front outboard passenger
frontal airbag and knee airbag, the OFF
indicator will light and stay lit as a reminder
that the airbags are off. See Passenger
Airbag Status Indicator 0101.
The passenger sensing system is designed to
turn on the front outboard passenger frontal
airbag and knee airbag, anytime the system senses that a person of adult size is sitting
properly in the front outboard
passenger seat.
When the passenger sensing system has
allowed the airbag to be enabled, the ON
indicator will light and stay lit as a reminder
that the airbags are active.
For some children, including children in child
restraints, and for very small adults, the
passenger sensing system may or may not
turn off the front outboard passenger
frontal airbag and knee airbag, depending
upon the person's seating posture and body
build. Everyone in the vehicle who has
outgrown child restraints should wear a seat
belt properly
—whether or not there is an
airbag for that person.{Warning
If the airbag readiness light ever comes
on and stays on, it means that
something may be wrong with the airbag
system. To help avoid injury to yourself
or others, have the vehicle serviced right
away. See Airbag Readiness Light 0101
for more information, including important
safety information.
If the On Indicator Is Lit for a Child
Restraint
The passenger sensing system is designed to
turn off the front outboard passenger
frontal airbag and knee airbag, if the system
determines that an infant is present in a
child restraint. If a child restraint has been
installed and the ON indicator is lit:
1. Turn the vehicle off.
2. Remove the child restraint from the vehicle.
3. Remove any additional items from the seat such as blankets, cushions, seat
covers, seat heaters, or seat massagers.
4. Reinstall the child restraint following the directions provided by the child restraint
manufacturer and refer to Securing Child
Restraints (With the Seat Belt in the Rear
Seat) 076 orSecuring Child Restraints
(With the Seat Belt in the Front Seat)
0 78.
Make sure the seat belt retractor is
locked by pulling the shoulder belt all
the way out of the retractor when
installing the child restraint, even if the
child restraint is equipped with a seat
