.Do not keep your foot under the bumper;
the liftgate will not activate.
.Do not touch the liftgate until it has
stopped moving.
.This feature may be temporarily disabled
under some conditions. If the liftgate
does not respond to the kick, open or
close the liftgate by another method or
start the vehicle. The feature will be
re-enabled.
When closing the liftgate using this feature,
there will be a short delay. The taillamps
will flash and a chime will sound. Step away
from the liftgate before it starts moving.
Vehicle Security
This vehicle has theft-deterrent features;
however, they do not make the vehicle
impossible to steal.
Vehicle Alarm System
This vehicle has an anti-theft alarm system.
The indicator light, on the instrument panel
near the windshield, indicates the status of
the system:
Off : Alarm system is disarmed.
On Solid : Vehicle is secured during the
delay to arm the system.
Fast Flash : Vehicle is unsecured. A door, the
hood, or the liftgate is open.
Slow Flash : Alarm system is armed.
Arming the Alarm System
1. Turn off the vehicle.
2. Lock the vehicle in one of two ways:
.Use the RKE transmitter.
.With a door open, press the
interior
Q.
3. After 30 seconds the alarm system will arm, and the indicator light will begin to
slowly flash indicating the alarm system
is operating. Pressing
Qon the RKE
transmitter a second time will bypass
the 30-second delay and immediately
arm the alarm system.
The vehicle alarm system will not arm if the
doors are locked with the key.
If the driver door is opened without first
unlocking with the RKE transmitter, the horn
will chirp and the lights will flash to indicate
pre-alarm. If the vehicle is not started,
or the door is not unlocked by pressing
K
on the RKE transmitter during the 10-second
pre-alarm, the alarm will be activated.
If a door, the hood, or the liftgate is opened
without first disarming the system, the turn
signals will flash and the horn will sound for
about 30 seconds. The alarm system will
then re-arm to monitor for the next
unauthorized event.
Disarming the Alarm System
To disarm the alarm system or turn off the
alarm if it has been activated:

Keys, Doors, and Windows 23
.PressKon the RKE transmitter.
.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 RKE
transmitter.
Unlocking the driver door with the key will
not disarm the system or turn off the alarm.
How to Detect a Tamper Condition
IfKis pressed on the RKE transmitter and
the horn chirps and the lights flash three
times, an alarm occurred previously while
the alarm system was armed.
If the alarm has been activated, a message
will appear on the Driver Information
Center (DIC).
Immobilizer
See Radio Frequency Statement 0354.
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 transmitter leaves the vehicle.
The immobilization system is disarmed
when the ignition is turned on or in ACC/
ACCESSORY and a valid Remote Keyless
Entry (RKE) transmitter is 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 your vehicle. Only a correctly
matched RKE transmitter will start the
vehicle. If the transmitter 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 ignition will not change from off to
on or ACC/ACCESSORY, and the RKE
transmitter appears to be undamaged, try
another transmitter. Or, you may try placing
the transmitter in the cupholder in the
center console. See
Remote Keyless Entry
(RKE) System Operation 07.
If the ignition mode will not change with
the other transmitter, or with the
transmitter in the cupholder, your vehicle
needs service. If the ignition does change
modes, the first transmitter may be faulty.
See your 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 to the vehicle. To program
additional transmitters, see “Programming
Transmitters to the Vehicle” underRemote
Keyless Entry (RKE) System Operation 07.
Do not leave the key or device that disarms
or deactivates the theft-deterrent system in
the vehicle.

{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. For more

Seat Belts
This section describes how to use seat belts
properly, and some things not to do.
{Warning
Do not let anyone ride where a seat belt
cannot be worn properly. In a crash,
if you or your passenger(s) are not
wearing seat belts, injuries can be much
worse than if you are wearing seat belts.
You can be seriously injured or killed by
hitting things inside the vehicle harder or
by being ejected from the vehicle. In
addition, anyone who is not buckled up
can strike other passengers in the vehicle.
It is extremely dangerous to ride in a
cargo area, inside or outside of a vehicle.
In a collision, passengers riding in these
areas are more likely to be seriously(Continued)
Warning (Continued)
injured or killed. Do not allow passengers
to ride in any area of the vehicle that is
not equipped with seats and seat belts.
Always wear a seat belt, and check that
all passenger(s) are restrained
properly too.
This vehicle has indicators as a reminder to
buckle the seat belts. See Seat Belt
Reminders 091.
Why Seat Belts Work
When riding in a vehicle, you travel as fast
as the vehicle does. If the vehicle stops
suddenly, you keep going until something
stops you. It could be the windshield, the
instrument panel, or the seat belts!
When you wear a seat belt, you and the
vehicle slow down together. There is more
time to stop because you stop over a longer
distance and, when worn properly, your
strongest bones take the forces from the
seat belts. That is why wearing seat belts
makes such good sense.
Questions and Answers About Seat Belts
Q: Will I be trapped in the vehicle after a
crash 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.

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.

If the word ON, and the on symbol, are lit
on the passenger airbag status indicator, it
means that the front outboard passenger
frontal airbag is allowed to inflate.
If the word OFF, and the off symbol, are lit
on the passenger airbag status indicator, it
means that the passenger sensing system
has turned off the front outboard passenger
frontal airbag.
If, after several seconds, both status
indicator lights remain on, or if there are no
lights at all, there may be a problem with
the lights or the passenger sensing system.
See your dealer for service.
{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
