Alarm System
Your vehicle may have one of the following alarm systems:
  • Perimeter alarm.
  • Perimeter alarm with interior sensors.
  • Category one alarm with interior sensors and battery back-up sounder.
Perimeter Alarm
The perimeter alarm is a deterrent against unauthorized access to your vehicle through the doors and the hood.
Interior Sensors
Interior Motion Sensors
Note:   Do not cover up the interior lamp unit sensors.
Note:   Do not arm the alarm with full guard if passengers, animals or other moving objects are inside your vehicle, as this could trigger the alarm.
The sensors act as a deterrent against unauthorized intrusion by sensing any movement within your vehicle.
Battery Back-up Sounder
The battery back-up sounder is an extra alarm system which will sound a siren when the alarm is triggered. When you lock your vehicle the system is armed. The sounder has its own battery and will sound an alarm siren even if someone disconnects your vehicle battery or the battery back-up sounder itself.
Triggering the Alarm
Once armed, the alarm is triggered in any of the following ways:
  • If someone opens a door, the liftgate or the hood without a valid key or remote control.
  • If you switch the ignition on without a valid key.
  • If the interior sensors detect movement within your vehicle.
  • On vehicles with a battery back-up sounder, if someone disconnects your vehicle battery or the battery back-up sounder itself.
If the alarm is triggered, the alarm horn will sound for 30 seconds and the hazard warning flasher will flash for five minutes.
Any further attempts to perform one of the above will trigger the alarm again.
Full and Reduced Guard
Full Guard
Full guard is the standard setting.
In full guard, the interior sensors are on when you arm the alarm.
Note:   This may result in false alarms if animals or moving objects are inside your vehicle.
Reduced Guard
In reduced guard, the interior sensors are off when you arm the alarm.
Note:   You can set the alarm to reduced quard for the current ignition cycle only.
Ask on Exit (If Equipped)
You can set the information display to ask you each time which level of guard you wish to set.
If you select Ask on Exit, the message Reduced guard appears in the information display each time you switch the ignition off.   See   Information Messages. 
If you wish to arm the alarm with reduced guard, press the OK button when this message appears.
If you wish to arm the alarm with full guard, leave your vehicle without pressing the OK button.
Selecting Full or Reduced Guard
Note:   Selecting reduced guard does not set the alarm permanently to reduced guard. It sets it to reduced guard only for the current ignition cycle. If you regularly set the alarm to reduced guard, select Ask on Exit.
You can select full or reduced guard using the information display.   See   General Information. 
Arming the Alarm
To arm the alarm, lock your vehicle.   See   Doors and Locks.
