Voice activation system
The concept
The voice activation system allows you to con-
trol operation of various vehicle systems with-
out ever removing your hands from the steering 
wheel.
Individual menu items on the Control Display 
can be spoken as commands. This frees you of 
having to use the controller.
The voice activation system transforms your 
oral commands into control signals for the 
selected systems and provides support in the 
form of instructions or questions.
The voice activation system uses a special 
microphone located in th e area of the interior 
rearview mirror, refer to page 14.
Precondition
Via iDrive, set the langua ge that applies for the 
voice activation system in  order to enable iden-
tification of the spoken commands. To set the 
language of iDrive, refer to page 90.

Central locking system
The concept
The central locking system functions when the 
driver's door is closed.
The system simultaneously engages and 
releases the locks on the following:
> Doors
> Liftgate
> Fuel filler door
Operating from outside
>via the remote control
> via the door lock
> with comfort access
* via the door handles
The interior lamps and the courtesy lamps
* are 
also switched on and off with the remote con-
trol. The alarm system
 is armed/disarmed at the 
same time.
You can find more detailed information on the 
alarm system
 on page 38.
Operating from inside
Via the button for centra l locking, refer to 
page 32. The fuel filler door is not locked.
In an accident of sufficient severity, the central 
locking system automati cally unlocks the vehi-
cle. In addition, the hazard warning flashers and 
interior lamps come on.
Opening and closing:
Using remote control
Persons or animals left unattended in a 
parked vehicle can lock the doors from 
the inside. Always take  along the remote control 
when leaving the vehicle so that the vehicle can 
then be opened  from the outside. <

Indicator lamp displays
>The indicator lamp under the interior rear-
view mirror flashes continuously: the sys-
tem is armed.
> The indicator lamp flashes after locking: 
The doors, hood, or liftgate 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.
> The indicator lamp goes out after unlocking: 
your vehicle has not been disturbed while 
you were away.
> The indicator lamp flashes after unlocking 
until the remote control  is inserted into the 
ignition lock, however for a maximum of 
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. in  case of an attempted 
wheel theft or towing.
Interior motion sensor
In order for the interior  motion sensor to func-
tion properly, the windows and glass sunroof
*/
panorama glass sunroof
* must be completely 
closed.
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, 
by sea 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 light s 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.
Comfort access*
Comfort access enables you to access your 
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 auto matically detects the 
related remote control in the immediate vicinity 
or in the interior.
Comfort access supports the following func-
tions:
> Unlocking/locking vehicle
> Comfort closing
> Opening liftgate
> Starting engine
Functional requirements
>The vehicle can only be unlocked if the 
vehicle detects that th e remote control car-
ried is not located in the vehicle interior.
> The next unlocking and locking cycle is not 
possible until after approx. 2 seconds.
