Keys, Doors, and Windows
Slow Flash:
Alarm system is
armed.
Arming the Alarm System
1. Turn off the vehicle.
2. Lock the vehicle with one of the
following:
.
Use the Remote Keyless
Entry (RKE) transmitter.
.
With a door open, press
Q
on the interior of the door.
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
Q
on the
RKE transmitter a second time
will bypass the 30-second delay
and immediately arm the alarm
system.
The theft-deterrent alarm system will
not arm if the doors are locked with
the key.
If the driver door is opened without
first unlocking 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 or the hood 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:
.
Press
K
on 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
If
K
is pressed on the RKE
transmitter and the horn chirps three
times, an alarm occurred previously
while the alarm system was armed.
