The concept

The vehicle alarm system responds:

> When a door, the hood or the trunk lid is opened
> To movements inside the vehicle: interior motion sensor,
> When the car's inclination changes, e.g. if an attempt is made to jack it up and steal the wheels or to raise it prior to towing away: tilt alarm sensor,
> When there has been an interruption of power supply from the battery

Depending on the market-specific  version, the alarm system briefly signals unauthorized entry attempts by:

> An acoustic alarm
> Switching onthe hazard warning flashers

Arming and disarming

When you lock or unlock the vehicle, either with the remote control or at the door lock, the alarm system is armed or disarmed at the same time.

You can open the trunk lid using the button of the remote control even if the alarm system is armed. The lid is locked and monitored again as soon as it is closed.

You can trigger the alarm system if you find yourself in a dangerous situation.

Press the button for at least three seconds. To switch off the alarm: press any button.

> Unlock the car with the remote control, , or insert the remote control all the way into the ignition lock.

> The indicator lamp under the inside rearview mirror flashes continuously: the system is armed.
> The indicator lamp flashes after locking: doors, hood or trunk lid are not properly closed. Even if you do not close the alerted area, the system begins to monitor the remaining areas, and the indicator lamp flashes continuously after approx. 10 seconds. The interior motion sensor and the tilt alarm sensor are not activated.

> The indicator lamp goes out after unlocking: your vehicle has not been disturbed while you were away.
> If the indicator lamp flashes after unlocking until the remote control is inserted in the ignition, but for no longer than approx.

5 minutes: your vehicle has been disturbed while you were away.

The tilt of the vehicle is monitored. The alarm system reacts, e.g. to attempts to steal a wheel or tow the vehicle.

Coupe

In order for the interior motion sensor to function properly, the windows and glass roofmust be completely closed.

Convertible

The interior of the car is monitored up to the height of the seat cushions. This way, the antitheft alarm system including the interior motion sensor are armed, even if the convertible top is open. Falling objects, e.g. tree leaves, may trigger a false alarm, refer to Avoiding false alarms.

The tilt alarm sensor and interior motion sensor may be switched off at the same time. This prevents unintentional alarms, e.g. in the following situations:

> In duplex garages
> During transport on car-carrying trains, boats/ships or on a trailer
> When animals are to remain in the vehicle

Switching off tilt alarm sensor and interior motion sensor

Press the button on the remote control again as soon as the vehicle is locked.

The indicator lamp lights up briefly and then flashes continuously. The tilt alarm sensor and the interior motion sensor are switched off until the next time the vehicle is unlocked and subsequently locked again.
