In dialogs that call for a text of your choice, the 
procedure can only be canceled using the but-
ton on the steering wheel.
Possible commands
The commands available in each case depend 
on the menu item selected on the Control Dis-
play.
To have the available commands read aloud:
For example, if "CD/DVD" is selected, the com-
mands for operating CD/Multimedia are read 
aloud.
Calling up functions immediately via 
short commands
With short commands you can run certain func-
tions directly, regardless of which menu item is 
selected, refer to page227.
Example: selecting the track of a CD
1.If necessary, switch on entertainment audio 
output.
2.Press the   button on the steering wheel.
Setting the voice dialog
You can set whether the system should use the 
standard dialog or a shorter variant. In the 
shorter variant of the voice dialog, the prompts 
and responses from the system are abbrevi-
ated.

Notes
To operate the telephone by voice, refer 
to page173.<
For voice commands, bear in mind the follow-
ing:
>Do not use the voice activation system to 
initiate an Emergency Request. In stressful 
situations, the voice and vocal pitch can 
change. This can unnecessarily delay the 
establishment of a telephone connection.
>Pronounce the commands and digits 
smoothly and at normal volume, avoiding 
excessive emphases and pauses. This also 
applies when spelling out and saying a full 
word during destination entry.
>When selecting a radio station, use the 
standard pronunciation of the station name.
>For entries in the voice-activated phone 
book, only use names in the language of the 
voice activation system and no abbrevia-
tions.
>Keep the doors, windows and glass sun-
roof
* or panorama glass sunroof* closed to 
prevent interference from ambient noise.
>Avoid ambient noise in the vehicle while 
speaking. {Voice commands}

Alarm system*
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, refer to page32
>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: tilt alarm sensor, refer to 
page32
>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 on
* the 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, refer to page28. The lid is locked and 
monitored again as soon as it is closed.
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.

view mirror flashes continuously: the sys-
tem 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.
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

quently locked again.
Comfort Access*
Comfort Access enables you to enter your vehi-
cle without needing to hold the remote control 
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.
Comfort Access supports the following func-
tions:
>Unlocking/locking the vehicle
>Unlocking the trunk lid separately
>Engine starting
>Convenient closing

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.
