Vehicle Alarm System

The indicator light, on the driver door

Arming the Alarm System
1. Turn off the vehicle.
2. Lock the vehicle in one of three ways:
Use the remote key.
Use the Keyless Access system.
With a door open, press on the
interior of the door.
3. After 30 seconds the alarm system will
arm, and the indicator light will begin to
slowly flash. Pressing on the remote
key 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 mechanical key.
If the driver door is opened without first
unlocking with the remote key, 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 remote key during the 10-second
pre-alarm, the alarm will be activated.
The alarm will also be activated if a
passenger door, the tailgate/power swing
gate, 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.
Disarming the Alarm System
To disarm the alarm system or turn off the
alarm if it has been activated:
Press on the remote key.
Unlock the vehicle using the Keyless
Access system.
Start the vehicle.
