dangerous and children or others could
be seriously injured or killed. They could
operate the power windows or other
controls or make the vehicle move. The
windows will function with the RKE
transmitter in the vehicle, and children or
others could be caught in the path of a
closing window. Do not leave children in

For improved vehicle security, the RKE
transmitter is equipped with a motion
sensor. When starting the vehicle, if the
transmitter has been idle for a while, move
the transmitter slightly and try starting the
vehicle. When starting the vehicle, if the
transmitter battery is depleted or there is
signal interference, the DIC may display NO
REMOTE DETECTED, REPLACE BATTERY IN KEY,
or NO REMOTE DETECTED PLACE KEY IN KEY

fully inserted. Remove the key and insert it
again. If this does not reset the lock, turn
the key halfway around in the cylinder and
repeat the reset procedure.

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 DIC messages
and make sure the liftgate is closed and
latched before driving.

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. Close the liftgate and the hood. Turn off
the vehicle.
2. Lock the vehicle in one of three ways:
.Use the RKE transmitter.
.Use the Keyless Access system.
.With a door open, press the
inside
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.
The alarm will also be activated if a
passenger door, the liftgate, or the hood is
opened without first disarming the system.
When the alarm is activated, the turn
signals flash and the horn sounds for about
30 seconds. The alarm system will then
re-arm to monitor for the next unauthorized
event.

.PressKon the RKE transmitter.
.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 RKE
transmitter or use the Keyless Access
system.
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 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 0353.
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 ACC/
ACCESSORY 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 into the
transmitter pocket located in the center
console. See Starting the Vehicle With a Low
Transmitter Battery under
Remote Keyless
Entry (RKE) System Operation 07.
If the ignition mode will not change with
the other transmitter or with a transmitter
in the transmitter pocket, 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 for the vehicle. To program
additional transmitters, see Programming
Transmitters to the Vehicle under Remote
Keyless Entry (RKE) System Operation 07.
