OnStar Overview
0 340.
Remote Key
See Radio Frequency Statement 0337.
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

20 Keys, Doors, and Windows
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 obstructions such as a garage
door or roof-mounted cargo. The liftgate
can be manually opened all the way.
.OFF: Opens manually only.
To power open or close the liftgate, select
MAX or 3/4 mode.
.Pressbtwice quickly on the remote
key until the liftgate moves.
.Press8on the driver door. The driver
door must either be unlocked or locked
without the security armed.
.Press the touch pad in the liftgate handle
after unlocking all doors. The remote key
must be within 1 m (3 ft).
.Presslon the bottom of the liftgate.
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 in 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 Driver
Information Center (DIC) messages and make
sure the liftgate is closed and latched before
driving.
Falling Liftgate Detection
If the power liftgate automatically closes
after a power opening cycle, it indicates that
the system is reacting to excess weight on
the liftgate or a possible support strut
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

26 Keys, Doors, and Windows
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 ignition will not change from off to
on or ACC/ACCESSORY, and the remote key
appears to be undamaged, try another
remote key. Or, you may try placing the
remote key in the cupholder in the center
console. SeeRemote Key Operation 07.
If the vehicle will not start with the other
remote key, or with the remote key in the
cupholder, the vehicle needs service. If the
vehicle does start, 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 to
the vehicle. To program additional remote
keys, see “Programming remote keys to the
Vehicle” underRemote Key Operation 07.
Do not leave the remote key or device that
disarms or deactivates the theft-deterrent
system in the vehicle.Exterior Mirrors

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 0338 and
Event Data Recorders 0339.
.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 0100.
The passenger sensing system turns off the
front outboard passenger frontal 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

Seats and Restraints 59
{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. SeeAirbag Readiness Light 099
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 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 Belts in the
Rear Seat) 074 or
Securing Child Restraints (With the Seat
Belts in the Front Seat) 075.
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
belt lock off. When the retractor lock is
set, the belt can be tightened but not
pulled out of the retractor.
5. If, after reinstalling the child restraint and restarting the vehicle, the ON
indicator is still lit, turn the vehicle off.
Then slightly recline the vehicle seatback
and adjust the seat cushion,
if adjustable, to make sure that the
vehicle seatback is not pushing the child
restraint into the seat cushion.
Also make sure the child restraint is not
trapped under the vehicle head restraint.
If this happens, adjust the head restraint.
See Head Restraints 034.
6. Restart the vehicle. The passenger sensing system may or may
not turn off the airbag for a child in a child
restraint depending upon the child’s size.
It is better to secure the child restraint in a
rear seat. Never put a rear-facing child
restraint in the front seat, even if the ON
indicator is not lit.
If the Off Indicator Is Lit for an
Adult-Sized Occupant
If a person of adult size is sitting in the
front outboard passenger seat, but the OFF
indicator is lit, it could be because that
person is not sitting properly in the seat or
that the child restraint locking feature is
