Alarm system*
The concept
The vehicle alarm system responds:
>When a door, the hood or the luggage com-
partment lid is opened
>To movements inside the vehicle: Interior 
motion sensor, refer to page36
>When the car's inclination changes, for 
instance if an attempt is made to jack it up 
and steal the wheels or to raise it prior to 
towing away
>When there is an interruption in the power 
supply from the battery
The alarm system signals unauthorized entry 
attempts for a short time by means of:
>An acoustic alarm
>Switching on the hazard warning flashers
>Flashing the high beams
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 luggage compartment lid 
even when the alarm system is armed, by 
pressing the   button on the remote control, 
refer to page31. The lid is locked and moni-
tored again as soon as you close it.
Panic mode*
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.
Switching off an alarm
>Unlock the car with the remote control, refer 
to page29.
>Insert the remote control all the way into the 
ignition lock.
Indicator lamp displays
>The indicator lamp under the inside rear-
view mirror flashes continuously: the sys-
tem is armed.
>The indicator lamp flashes after locking: 
doors, hood or luggage compartment lid are 
not properly closed. Even if you do not close 
the alerted area, the system begins to mon-
itor 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. 

Opening and closing
36 >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.
Tilt alarm sensor
The tilt of the vehicle is monitored. The alarm 
system reacts, e.g. to attempts to steal a wheel 
or tow the vehicle.
Interior motion sensor
Coupe
In order for the interior motion sensor to func-
tion properly, the windows and glass roof must 
be completely closed
*.
Convertible
The interior of the car is monitored up to the 
height of the seat cushions. Thus the alarm sys-
tem is activated together with the interior 
motion sensor even if the hardtop is open. The 
alarm can be triggered unintentionally by falling 
objects such as leaves, refer to Avoiding unin-
tentional 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 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 subse-
quently locked again.
Convenient access*
Convenient access enables you to enter your 
vehicle without needing to hold the remote con-
trol in your hand. All you need to do is wear the 
remote control close to your body, e.g. in your 
jacket pocket. The vehicle detects the corre-
sponding remote control within the immediate 
vicinity or in the passenger compartment.
Convenient access supports the following 
functions:
>Unlocking/locking the vehicle
>Unlocking the luggage compartment lid 
separately
>Engine starting
>Convenient closure
Functional requirement
>The vehicle or the luggage compartment lid 
can only be locked when the vehicle detects 
that the remote control currently in use is 
outside of the vehicle.
>The vehicle cannot be locked or unlocked 
again until after approx. 2 seconds.
>The engine can only be started when the 
vehicle detects that the remote control cur-
rently in use is inside the vehicle.
