Voice command system

Voice command system  
The concept 
The voice command system allows you to 
control operation of various vehicle sys-
tems without ever removing your hands 
from the steering wheel. 
The menu items on the Control Display 
serve as voice commands for the equip-
ment that can be operated using the voice 
command system. This means you can 
open these menu items using the voice 
command system instead of with the con-
troller. 
The voice command system transforms 
your oral commands into control signals for 
the selected systems and provides support 
in the form of instructions or questions. 
Precondition 
If the language of the voice command and 
Control Display do not match, change the 
language of the Control Display, refer to 
page 74.

Central locking system 
The concept 
The central locking system is ready for 
operation whenever the driver's door is 
closed. This simultaneously engages and 
releases the locks on the following: 
>Doors 
>Luggage compartment lid 
>Fuel filler door. 
The central locking system can be oper-
ated from the outside 
>via the remote control 
>via the driver's door lock 
and from inside via the button for the cen-
tral locking system. 
When the system is locked from inside, the 
fuel filler door remains unlocked, refer to 
page 30. 
The anti-theft system is automatically acti-
vated whenever you operate the central 
locking system from outside the vehicle. It 
prevents the doors from being unlocked 
using the safety lock buttons or door han-
dles. The alarm system is armed/disarmed 
at the same time. 
In the event of an accident, the central 
locking system automatically unlocks the 
vehicle. In addition, the hazard warning 
flashers and interior lamps come on. 
Opening and closing: from 
outside 
Using the remote control 
The remote control provides two additional 
functions for the central locking system: 
>Switching on the interior lamps, refer to 
page 28. 
You can also use this function to locate 
your vehicle in parking garages etc. 
>Opening the luggage compartment lid, 
refer to page 28.
The luggage compartment lid opens, 
regardless of whether it was previously 
locked or unlocked. 
In addition, the remote control offers you 
another function:
>Panic mode 
In case of danger, you can trigger an 
alarm.
When you lock/unlock the vehicle, you 
simultaneously activate/deactivate the 
anti-theft system, arm/disarm the alarm 
system, and switch the interior lamps on/
off.
Protect the remote control against 
unauthorized use by handing over 
only the spare key, for example when using 
hotel valet parking.< 
Because any persons or animals left 
unattended in a parked vehicle could 
lock the doors from the inside, you should 
always keep the remote control with you; 
this precaution ensures that you will remain 
able to unlock the vehicle from the outside 
at all times.<
