Once armed, the alarm will go off if
someone tries to enter the vehicle
without using the RKE transmitter or
a key or turns the ignition on with an
incorrect key. The horn will sound
and the turn signal lamps will flash
for about 30 seconds.
When the alarm is armed, the trunk
may be opened with the RKE
transmitter. The power door lock
switches are disabled and the doors
remain locked. You must use your
RKE transmitter or your key to
unlock the doors when the system is
armed.
Arming with the Power Lock
Switch
The alarm system will arm when
you use either power lock switch to
lock the doors while any door is
open and the key is removed from
the ignition. The alarm system will
not arm if the trunk is open when
you use either power lock switch to
lock the doors.
Arming with the RKE
Transmitter
The alarm system will arm when
you use your RKE transmitter to
lock the doors, if the key is not in
the ignition.
Disarming with the RKE
Transmitter
The alarm system will disarm when
you use your RKE transmitter to
unlock the doors.
The first time a remote unlock
command is received, three flashes
will be seen and three horn chirps
heard to indicate an alarm condition
has occurred since last arming.
Disarming with Your Key
The alarm system will disarm when
you use your key to unlock the
doors or insert your key in the
ignition and turn it from the LOCK/
OFF position.
