To disarm the alarm system or turn off the
alarm if it has been activated, do one of the
following:
.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

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.
Inclination Sensor and Intrusion Sensor
In addition to the standard theft-deterrent
system features, this system may also have
an inclination sensor and intrusion sensor.
The inclination sensor can activate the alarm
if it senses movement of the vehicle, such
as a change in vehicle orientation.
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 both doors and windows are
completely closed.
.Secure any loose items such as
sunshades.
.Make sure there are no obstructions
blocking the sensors.
Intrusion and Inclination Sensors Disable
Switch
It is recommended that the intrusion and
inclination sensors be deactivated if pets are
left in the vehicle or if the vehicle is being
transported. When the roof panel is off, or the
convertible top is down, the intrusion
system is turned off.
With the vehicle turned off, press
oon the
overhead console, next to OnStar. The
indicator light will display momentarily,
indicating that these sensors have been
disabled until the next time the alarm
system is armed.
Immobilizer
See Radio Frequency Statement 0316.
Immobilizer Operation
The vehicle has a passive theft-deterrent
system.
The security light comes on in the
instrument cluster if there is a problem with
arming or disarming the theft-deterrent
system. This light also comes on briefly
when the engine is started.

The system is automatically armed when
the ignition is turned off.
The immobilization system is disarmed
when the ignition is turned on or placed in
ACC/ACCESSORY and a valid remote key is
found in the vehicle.
You do not have to manually arm or disarm
the system.
The system has one or more remote keys
that are matched to an immobilizer control
unit in the vehicle. Only a correctly matched
remote key starts the vehicle. The vehicle
may not start if the remote key is damaged.
If the engine does not start and the security
light comes on, there may be a problem
with the immobilizer system. Try starting
the vehicle again.
If the vehicle does not start and the remote
key appears to be undamaged, try another
remote key. Or, place the remote key in the
cupholder backup location. SeeRemote
Keyless Entry (RKE) System Operation 07.
If the engine still does not start with the
other remote key, or with the remote key in
the cupholder backup location, the vehicle
needs service. If the engine does start, the first remote key may be faulty. See your
dealer or have a new remote key
programmed to the vehicle.
The immobilizer system can 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 Keyless Entry (RKE)
System Operation 07.
Do not leave the remote key or device that
disarms or deactivates the theft-deterrent
system in the vehicle.

Heated and Ventilated Front
Seats
{Warning
If temperature change or pain to the skin
cannot be felt, the seat heater may cause
burns. To reduce the risk of burns, use
care when using the seat heater,
especially for long periods of time. Do
not place anything on the seat that
insulates against heat, such as a blanket,
cushion, cover, or similar item. This may
cause the seat heater to overheat. An
overheated seat heater may cause a burn
or may damage the seat.
If equipped, the buttons are near the
climate controls on the console. To operate,
the engine must be running.
Press

Questions and Answers About Seat Belts
Q: Will I be trapped in the vehicle after acrash if I am wearing a seat belt?
A: You could be— whether you are
wearing a seat belt or not. Your chance
of being conscious during and after a
crash, so you canunbuckle and get out,
is much greater if you are belted.
Q: If my vehicle has airbags, why should I have to wear seat belts?
A: Airbags are supplemental systems only.
They work withseat belts —not instead
of them. Whether or not an airbag is
provided, all occupants still have to
buckle up to get the most protection.
Also, in nearly all states and in all
Canadian provinces, the law requires
wearing seat belts.
Buckle To Drive
If equipped, this feature prevents the vehicle
from shifting out of P (Park) when the driver
seat belt is not buckled. The Buckle to Drive
feature must be turned ON in the
infotainment system to work. See Vehicle
Personalization 098 and if equipped, Teen
Driver 0160. If the engine is running, the
driver seat belt is not buckled, and the brake pedal is pressed with the vehicle in P (Park),
a message displays in the Driver Information
Center (DIC). Buckle the driver seat belt to
shift out of P (Park). Shifting from P (Park)
will be prevented once for each ignition
cycle.
For some fleet vehicles, the feature is
always ON and it cannot be turned OFF in
the infotainment system. Shifting from
P (Park) will be prevented each time the
above conditions exist.
On some models, Buckle to Drive may also
prevent shifting out of P (Park) if a front
passenger is unbuckled under similar
conditions. A message displays in the DIC.
Buckle the front passenger seat belt to shift
out of P (Park). This feature may not allow
the vehicle to shift out of P (Park) if an
object, such as a briefcase, handbag, grocery
bag, laptop, or other electronic device, is on
the front passenger seat. If this happens,
remove the object from the seat or buckle
the seat belt to shift out of P (Park).
If the driver, or on some vehicles, the
present front passenger remains unbuckled,
the DIC message will turn off after several
seconds and the vehicle can be shifted out
of P (Park). See
“Seat Belts”and“Child Restraints”
in the Index for information
about the importance of proper
restraint use.
If the driver seat belt, and in some vehicles
the front passenger seat belt, is unbuckled
when driving, the seat belt reminder chime
and light(s) will come on. See Seat Belt
Reminders 084. This feature may not
function properly if the airbag readiness
light is on. See Airbag Readiness Light 085.
How to Wear Seat Belts Properly
Follow these rules for everyone's protection.
There are additional things to know about
seat belts and children, including smaller
children and infants. If a child will be riding
in the vehicle, see Older Children061 or
Infants and Young Children 062. Review
and follow the rules for children in addition
to the following rules.
It is very important for all occupants to
buckle up. Statistics show that unbelted
people are hurt more often in crashes than
those who are wearing seat belts.
There are important things to know about
wearing a seat belt properly.

components of the airbag module may be
hot for several minutes. For location of the
airbags, seeWhere Are the Airbags? 054.
The parts of the airbag that come into
contact with you may be warm, but not too
hot to touch. There may be some smoke
and dust coming from the vents in the
deflated airbags. Airbag inflation does not
prevent the driver from seeing out of the
windshield or being able to steer the
vehicle, nor does it prevent people from
leaving the vehicle.
{Warning
When an airbag inflates, there may be
dust in the air. This dust could cause
breathing problems for people with a
history of asthma or other breathing
trouble. To avoid this, everyone in the
vehicle should get out as soon as it is
safe to do so. If you have breathing
problems but cannot get out of the
vehicle after an airbag inflates, then get
fresh air by opening a window or a door.
If you experience breathing problems
following an airbag deployment, you
should seek medical attention. The vehicle has a feature that may
automatically unlock the doors, turn on the
interior lamps and hazard warning flashers
after the 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.
(Continued)
Warning (Continued)
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 0317 and
Event Data Recorders 0318.
.Let only qualified technicians work on the
airbag system. Improper service can mean
that the airbag system will not work
properly. See your dealer for service.
