Vehicle Security

This vehicle has theft-deterrent
features; however, they do not make
the vehicle impossible to steal.

Vehicle Alarm System

On vehicles with an anti-theft alarm
system, to activate the system:
Press on the Remote Keyless
Entry (RKE) transmitter or the
power door lock switch when
any door is open.
The security light flashes.
When the door is closed, the
security light stops flashing and
stays on solid for approximately
30 seconds. The content
theft-deterrent alarm is not
armed until the security light
goes off.
If the delayed locking feature is
active, the alarm is not activated
until all doors are closed and the
security light goes off.
Press when the driver door is
closed. The security light comes
on solid for approximately
30 seconds and then goes off.
The content theft-deterrent alarm
is not armed until the security
light goes off.
The theft-deterrent system will not
activate if the doors are locked with
the vehicle's key or the manual
door lock.
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 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.
The vehicle can be started with the
correct ignition key if the alarm has
been set off.
To avoid setting off the alarm by
accident:
Lock the vehicle with the door
key after the doors are closed.
Unlock the door with the RKE
transmitter. Unlocking a door any
other way sets off the alarm if
the system has been armed.
Press or place the key in the
ignition and turn it to START to turn
off the alarm.
