Indicator lamp displays
>The indicator lamp below the interior rear-
view mirror flashes continuously: the sys-
tem is armed.
>The indicator lamp flashes after locking: the
doors or luggage compartment 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 sec-
onds. However, the interior motion sensor
is not activated.
>After the vehicle is unlocked, the indicator
lamp goes out: no manipulation or
attempted intrusions have been detected in
the period since the system was armed.
>The indicator lamp flashes after unlocking
until the remote control is inserted into the
ignition lock, however for a maximum of
approx. 5 minutes: an attempted entry has
been detected in the period since the sys-
tem was armed.
Tilt alarm sensor
Monitors the inclination of the vehicle. The
alarm system reacts, for example, if someone
attempts to steal the wheels or tow the vehicle.
Interior motion sensor
Coupe:
In order for the interior motion sensor to func-
tion properly, the windows and glass sunroof
*
must be completely closed.
Convertible:
Monitors the interior up to the height of the seat
cushions. This means that the alarm system,
including the interior motion sensor, is armed even if the convertible top is open. Falling
objects, e.g. leaves, can trigger false alarms,
refer to Avoiding unintentional alarms.
Avoiding unintentional alarms
The tilt alarm sensor and interior motion sensor
may be switched off at the same time. This pre-
vents unintentional alarms, e.g. in the following
situations:
>In stacking garages
>When transporting on car-carrying trains
>When animals are to remain in the vehicle
Switching off the tilt alarm sensor and
interior motion sensor
Press the button on the remote control
once again immediately after locking.

flashes continuously. The tilt alarm sensor and
the interior motion sensor are switched off until
the vehicle is unlocked and locked again.

vehicle without having to hold the remote con-
trol in your hand. It is sufficient to carry the
remote control with you, e.g. in your jacket
pocket. The vehicle automatically detects the
related remote control in the immediate vicinity
or in the interior.
Comfort access supports the following func-
tions:
>Unlocking/locking vehicle
>Starting engine
>Comfort locking
Functional requirement
>The vehicle can only be unlocked if the
vehicle detects that the remote control car-
ried is located outside the vehicle.
>The next unlocking and locking cycle is not
possible until after approx. 2 seconds.
