KEYS, DOORS, AND WINDOWS 11
Programming Remote Keys to
the Vehicle
Only remote keys programmed to the
vehicle will work. If a remote key is
lost or stolen, a replacement can be
purchased and programmed through
your dealer. The vehicle can be
reprogrammed so that lost or stolen
remote keys no longer work. Each
vehicle can have up to eight remote
keys matched to it.
Starting the Vehicle with a Low

For improved vehicle security, the
remote key is equipped with a motion
sensor. When starting the vehicle,
if the remote key has been idle for a
while, the DIC may display KEY IN
SLEEP MODE, MOVE KEY, THEN
START. Move the remote key slightly
and try starting the vehicle. When
starting the vehicle, if the remote key
battery is depleted or there is signal
interference, the DIC may display NO
KEY FOUND, REPLACE BATTERY IN
KEY or NO REMOTE KEY WAS
DETECTED PLACE KEY IN KEYPOCKET THEN START YOUR
VEHICLE, follow the steps shown
below:
1. Place the remote key into the rear
cupholder.
2. With the vehicle in P (Park) or N (Neutral) press the brake pedal
and ENGINE START/STOP.
Replace the remote key battery as
soon as possible.

{Warning
Never allow children to play with
the remote key. The remote key
contains a small battery, which can
be a choking hazard. If swallowed,
internal burns can occur, resulting
in severe injury or death. Seek
medical attention immediately if a
battery is swallowed.
{Warning
To avoid personal injury, do not
touch metal surfaces on the remote
key when it has been exposed to
extreme heat. These surfaces can be
hot to the touch at temperatures
above 59 °C (138 °F).
Caution

sounds for about 30 seconds. The
alarm system will then re-arm to
monitor the next unauthorized event.
Disarming the Alarm System
To disarm the alarm system or turn
off the alarm if it has been activated:
.PressKon the remote key.
.Unlock the vehicle using the Keyless
Access system.
.Start the vehicle.
To avoid setting off the alarm by
accident:
.Lock the vehicle after all occupants
have left the vehicle and all doors
are closed.
.Always unlock a door with the
remote key or use the Keyless
Access system.
Unlatching the driver door with the
mechanical key will not disarm the
system or turn off the alarm.
How to Detect a Tamper
Condition
IfKis pressed on the remote key and
the horn chirps and the lights flash
three times, a previous alarm occurred
while the system was armed.
If the alarm has been activated, a
message will appear on the DIC.
Power Sounder, Inclination
Sensor, and Intrusion Sensor
In addition to the standard
theft-deterrent system features, this
system may also have a power
sounder, inclination sensor, and
intrusion sensor.
The power sounder provides an
audible alarm which is distinct from
the vehicle’s horn. It has its own
power source, and can sound an alarm
if the vehicle’s battery is
compromised.
The inclination sensor can set off the
alarm if it senses movement of the
vehicle, such as when a tire is
removed. Make sure the vehicle's
alarm is not armed prior to any
jacking. The intrusion sensor monitors the
vehicle interior, and can activate the
alarm if it senses unauthorized entry
into the vehicle's interior. Do not allow
passengers or pets to remain in the
vehicle when the intrusion sensor is
activated.
Before arming the theft-deterrent
system and activating the intrusion
sensor:
.Make sure all doors and windows
are completely closed.
.Secure any loose items such as sun
glasses.
.Make sure there are no obstructions
blocking the sensors in the front
overhead console.

Inclination and Intrusion Sensor
Disable Switch
It is recommended that the intrusion
and inclination sensor be deactivated
if pets are left in the vehicle or the
vehicle is being transported. With the
vehicle turned off, press
oin the
front overhead console. The indicator
light will come on momentarily,
indicating that these sensors have
been disabled for the next alarm
system arming cycle.
Immobilizer
See Radio Frequency Statement 0438.
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 turned
on or to ACC/ACCESSORY 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 the 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.
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 (ACC/ACCESSORY, on, off), and
the remote key appears to be
undamaged, try another remote key.
Or, you may try placing the remote
key in the backup location. See
Remote Keyless Entry (RKE) System
Operation
07.
If the ignition modes will not change
with the other remote key or in the
backup location, the vehicle needs
service. If the ignition does change
modes, the first remote key may be
faulty. See your dealer.
It is possible for the immobilizer
system to learn new or replacement
remote keys. Up to eight remote keys

52 SEATS AND RESTRAINTS
restrain the occupants. The vehicle
has electronic sensors that help the
airbag system determine the severity
of the impact. Deployment thresholds
can vary with specific vehicle design.
Frontal airbags are designed to inflate
in moderate to severe frontal, or near
frontal, crashes to help reduce the
potential for severe injuries, mainly to
the driver's or front outboard
passenger's head and chest.
Whether the frontal airbags will or
should inflate is not based primarily
on how fast the vehicle is traveling.
It depends on what is hit, the
direction of the impact, and how
quickly the vehicle slows down.
Frontal airbags may inflate at
different crash speeds depending on
whether the vehicle hits an object
straight on or at an angle, and
whether the object is fixed or moving,
rigid or deformable, narrow or wide.
Frontal airbags are not intended to
inflate during vehicle rollovers, in rear
impacts, or in many side impacts.In addition, the vehicle has advanced
technology frontal airbags. Advanced
technology frontal airbags adjust the
restraint according to crash severity.
Knee airbags are designed to inflate in
moderate to severe frontal or near
frontal impacts. Knee airbags are not
designed to inflate during vehicle
rollovers, in rear impacts, or in many
side impacts.
Seat-mounted side impact airbags are
designed to inflate in moderate to
severe side crashes depending on the
location of the impact. Seat-mounted
side impact airbags are not designed
to inflate in frontal impacts, near
frontal impacts, rollovers, or rear
impacts. A seat-mounted side impact
airbag is designed to inflate on the
side of the vehicle that is struck.
Roof-rail airbags are designed to
inflate in moderate to severe side
crashes depending on the location of
the impact. In addition, these 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 wheneither 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 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, see
Where Are the
Airbags? 050.
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

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
0 439 and
Event Data Recorders 0440.
.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 098.
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.

massagers can affect how well the
passenger sensing system operates.
We recommend that you not use seat
covers or other aftermarket equipment
except when approved by GM for your
specific vehicle. SeeAdding Equipment
to the Airbag-Equipped Vehicle 058 for
more information about modifications
that can affect how the system
operates.
The ON indicator may be lit if an
object, such as a briefcase, handbag,
grocery bag, laptop, or other electronic
device, is put on an unoccupied seat.
If this is not desired, remove the
object from the seat.
{Warning
Stowing 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 Publication Ordering
Information 0437.
{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,
including improperly repairing or
replacing, any parts of the following:
.Airbag system, including airbag
modules, front or side impact
sensors, sensing and diagnostic
module, or airbag wiring
.Front seats, including stitching,
seams or zippers
.Seat belts
.Steering wheel, instrument panel,
overhead console, ceiling trim,
or pillar garnish trim
.Inner door seals, including speakers
Your dealer and the service manual
have information about the location of
the airbag modules and sensors,

sensing and diagnostic module, and
airbag wiring along with the proper
replacement procedures.
In addition, the vehicle has a
passenger sensing system for the front
outboard passenger position, which
includes sensors that are part of the
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 could either
prevent proper deployment of the
passenger airbag(s) or prevent the
passenger sensing system from
properly turning off the passenger
airbag(s). SeePassenger Sensing
System 054.
If the vehicle has rollover roof-rail
airbags, see Different Size Tires and
Wheels 0380 for additional important
information. If the vehicle must be modified
because you have a disability and 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 0430.
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 098.
Caution
If an airbag covering is damaged,
opened, or broken, the airbag may
not work properly. Do not open or
break the airbag coverings. If there
are any opened or broken airbag
coverings, have the airbag covering
and/or airbag module replaced. For
the location of the airbags, see
Where Are the Airbags? 050. See
your dealer for service.
Replacing Airbag System
Parts after a Crash
{Warning
A crash can damage the airbag
systems in the vehicle. A damaged
airbag system may not properly
protect you and your passenger(s)
in a crash, resulting in serious
injury or even death. To help make
sure the airbag systems are working
properly after a crash, have them
inspected and any necessary
replacements made as soon as
possible.
If an airbag inflates, you will need to
replace airbag system parts. See your
dealer for service.
If the airbag readiness light stays on
after the vehicle is started or comes
on when you are driving, the airbag
system may not work properly. Have
the vehicle serviced right away. See
