alarm if it has been activated:
.PressKon the RKE transmitter.
.Unlock the vehicle using the Keyless
Access system.
.Start the vehicle.

How to Detect a Tamper Condition
IfKis 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 0335.
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 transmitter 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 RKE
transmitters matched to an immobilizer
control unit in the vehicle. Only a correctly
matched RKE transmitter will start the
vehicle. If the transmitter is ever damaged,
the vehicle may not start. 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, and the RKE transmitter appears to
be undamaged, try another transmitter. Or,
try placing the transmitter in the
transmitter pocket located in the center
console. See Starting the Vehicle With a Low
Transmitter Battery under
Remote Key
Operation (Mechanical Key) 010 or
Remote Key Operation (Remote Key) 013.
If the ignition mode will not change with
the other transmitter or with a transmitter
in the transmitter pocket, the vehicle needs
service. If the ignition does change modes,
the first transmitter may be faulty. See a
dealer who can service the theft-deterrent
system and have a new RKE transmitter
programmed to the vehicle.
It is possible for the immobilizer system
to learn new or replacement RKE
transmitters. Up to eight transmitters can be
programmed for the vehicle. To program
additional transmitters, see Programming

Folding Seatback
The front passenger seatback may fold flat.
{Warning
If you fold the seatback forward to carry
longer objects, such as skis, be sure any
such cargo is not near an airbag. In a
crash, an inflating airbag might force that
object toward a person. This could cause
severe injury or even death. Secure
objects away from the area in which an
airbag would inflate.
Where Are the
Airbags? 054. Vehicle Load Limits 0181.
{Warning
Things you put on this seatback can
strike and injure people in a sudden stop
or turn, or in a crash. Remove or secure
all items before driving.
To fold the seatback: 1. Lower the head restraint all the way. See Head Restraints 037.
2. Move the seat as far back as possible. See Seat Adjustment 039 or
Power Seat Adjustment 039.

Seats and Restraints 57
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,
and shut off the fuel system 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.
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 0336 and
Event Data Recorders 0337.
.Let only qualified technicians work on the
airbag systems. Improper service can
mean that an airbag system will not work
properly. See your dealer for service.

Warning Lights, Gauges, and
Indicators
Warning lights and gauges can signal that
something is wrong before it becomes
serious enough to cause an expensive repair
or replacement. Paying attention to the
warning lights and gauges could prevent
injury.
Some warning lights come on briefly when
the engine is started to indicate they are
working. When one of the warning lights
comes on and stays on while driving,
or when one of the gauges shows there
may be a problem, check the section that
explains what to do. Waiting to do repairs
can be costly and even dangerous.
