The alarm provides audible and visual warnings if anyone enters the car without a valid remote control key or manipulates the starter battery or alarm siren.

Alarm indicator

16w17- V90/S90-SPA - Larm indicator on the instument panel

A red LED on the instrument panel indicates the alarm system's status:

  • LED not lit – alarm not armed.
  • The LED flashes once every other second – alarm is armed.
  • After the alarm has been disarmed, the LED flashes rapidly for a maximum of 30 seconds or until ignition position I has been activated - the alarm has been triggered.
When armed, the alarm is triggered if:
  • a door, the bonnet or the tailgate is opened1
  • a movement is detected in the passenger compartment (if fitted with a movement detector*)
  • the car is raised or towed away (if fitted with a tilt detector*)
  • the starter battery's cable is disconnected
  • the siren is disconnected.

Alarm signals

When the alarm has been triggered, the following happens:
  • A siren sounds for 30 seconds or until the alarm is switched off.
  • Hazard warning flashers flash for 5 minutes or until the alarm is switched off.

If the cause of alarm activation is not rectified, the alarm cycle is repeated up to 10 times1.

Movement and tilt sensors*

Movement and tilt detectors react to movements inside the car2 e.g. if the window is broken or if anyone tries to tow the car away.

To avoid triggering the alarm unintentionally:
  • Close all windows when leaving the car.
  • Close the panoramic roof.
  • If the climate control is used – aim the airflow so that it does not point upwards in the passenger compartment.

It is also possible to reduce the alarm level in the centre display.
