The alarm system

The alarm is automatically armed whenever the vehicle is locked with the remote key or optional Personal Car Communicator.
When armed, the alarm continuously monitors a number of points on the vehicle. The following conditions will trigger the alarm:
- The hood is forced open.
- The trunk is forced open
- A door is forced open.
- The ignition slot is tampered with.
- An attempt is made to start the vehicle with a non-approved key (a key not coded to the car's ignition).
- If there is movement in the passenger compartment (if the vehicle is equipped with the accessory movement sensor).
- The vehicle is lifted or towed (if the vehicle is equipped with the accessory inclination sensor).
- The battery is disconnected (while the alarm is armed).
- The siren is disconnected when the alarm is disarmed.
A message will appear in the information display if a fault should occur in the alarm system. Contact a trained and qualified Volvo service technician.
NOTE
Do not attempt to repair any of the components in the alarm system yourself. This could affect the insurance policy on the vehicle.
