Voice command system

Notes
Do not use the voice command sys-
tem in emergency situations. In stress 
situations, voice and pitch can change.<
The portable phone can also be oper-
ated by voice control, refer to 
page 151.<
For voice commands, bear the following in 
mind:
>Issue the commands fluently and at 
normal volume, avoiding excessive 
emphasis and pauses
>Always speak commands with the pro-
nunciation of the voice command sys-
tem, as otherwise, for example, foreign 
radio stations will not be understood
>For entries in the voice-activated phone 
book, only use names in the language 
of the voice command system and no 
abbreviations
>Keep the doors, windows and glass 
roof or convertible top closed to pre-
vent interference from ambient noise
>Avoid other sources of noise in the 
vehicle while speaking, and ask other 
vehicle occupants to refrain from talk-
ing while you are using the system.

>Luggage compartment lid
>Fuel filler door.
The central locking system can be oper-
ated from the outside
>via the remote control
>via the door lock
and from inside via the button for the cen-
tral locking system.
If operated from the inside, the fuel filler 
door and the compartment in the front 
center console are not locked, refer to 
page 29.
The anti-theft system is automatically acti-
vated whenever you activate 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 unlocks automatically. The 
hazard warning flashers and interior lamps 
also switch on.
Opening and closing: from 
outside 
Using the remote control 
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.<
You can find more detailed information on 
the alarm system on page 32.
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.<

unlocks the driver's door only.
Turning the key a second time unlocks all of 
the remaining doors, the luggage compart-
ment lid and the fuel filler door.

Manual operation 
In the event of an electrical malfunction, 
you can turn the key all the way to the right 
or left in the door lock to lock or unlock the 
driver's door.
Opening and closing: from 
inside 
You can operate the central locking system 
with this button when the doors are closed. 
This only unlocks or locks the doors and 
luggage compartment lid, but the anti-theft 
system is not activated. The fuel filler door 
remains unlocked to enable refueling, as 
does the compartment in the front center 
console to ensure access to personal 
items.
You can also make the following settings:
>The central locking system automati-
cally locks the vehicle as soon as you 
drive off
>The central locking system automati-
cally locks the vehicle after a short time 
when no door has been opened.
Control Center, for principle details, refer to 
page 16:

3.Select "Door locks" and press the con-
troller
4.Select "Central locking" and press the

Opening and closing
32 If special circumstances should make it 
absolutely necessary to operate the vehicle 
with the lid open:
1.Coupe: close both windows as well as 
the glass roof
Convertible: with closed top, close all 
windows
2.Adjust the automatic climate control to 
supply a high air volume, refer to 
page 89.
Luggage compartment
There are four lashing eyes on the inner 
corners of the luggage compartment for 
securing luggage nets or securing straps to 
fix luggage in position.
Also refer to Cargo loading, page 104.
Convertible: increasing luggage 
compartment capacity 
With the convertible top closed, you can 
enlarge the luggage compartment capac-
ity:
To do so, unfold the handle and press it 
downwards in the direction of travel, refer 
to arrow. This folds the convertible top 
compartment floor upwards.
Before opening the convertible top, run this 
procedure in reverse order.
The convertible top cannot be 
opened if the convertible top com-
partment floor is folded up.<
Alarm system 
The concept 
The vehicle alarm system responds:
>When a door, the hood, or the luggage 
compartment lid is opened
>To movement in the vehicle interior: 
interior motion sensor
>To changing of the vehicle's tilt if some-
one attempts to steal the wheels or tow 
the vehicle
>To interruption of battery voltage.
The system responds to unauthorized vehi-
cle entry and attempted theft by simulta-
neously activating:
>An acoustic alarm, which lasts for a 
period of approx. 30 seconds 
>The hazard warning flashers for approx. 
5 minutes
>The high beams, which flash on and off 
in the same rhythm.
Arming and disarming alarm system 
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.
The system indicates that it has been cor-
rectly armed by switching on the hazard 
warning flashers for a single cycle and by 
emitting an acoustic signal.
You can also open the luggage compart-
ment lid with the system armed using but-
ton   on the remote control, refer to 
page 28. When you close the lid, it is 
secured again.
Switching off alarm 
>Unlock the vehicle using the remote 
control, refer to page 27
>or turn the ignition key to position 1.

Indicator lamp displays 
>The indicator lamp below the interior 
rearview mirror flashes continuously: 
the system is armed
>The indicator lamp flashes on locking: 
door(s) or luggage compartment lid are 
not completely closed. Even if you do 
not close the alerted area, the system 
begins to monitor the remaining areas, 
and the indicator lamp flashes continu-
ously after approx.10 seconds. How-
ever, the interior motion sensor is not 
activated
>The indicator lamp goes out on unlock-
ing: no manipulation or attempted intru-
sions have been detected in the period 
since the system was armed
>The indicator lamp flashes on unlocking 
before the remote control is inserted in 
the ignition lock, but for no more than 
roughly 5 minutes: an attempted entry 
has been detected in the period since 
the system was armed.
Following triggering of an alarm, the indica-
tor lamp will flash continuously.
Tilt alarm sensor and interior motion 
sensor 
Tilt alarm sensor
Monitors the inclination of the vehicle. The 
alarm system reacts, for example, if some-
one attempts to steal the wheels or tow the 
vehicle.
Interior motion sensor 
Coupe:
In order for the interior motion sensor to 
function properly, the windows and glass 
roof 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 sen-
sor, is armed even if the convertible top is 
open. Falling objects, e.g. leaves, can trig-
ger false alarms, refer to Avoiding uninten-
tional alarms.
Avoiding unintentional alarms 
The tilt alarm sensor and interior motion 
sensor may be switched off at the same 
time. This is how you prevent unintentional 
alarms, e.g. in the following situations:
>In garages with elevator ramps
>During transport on automobile trans-
port trains
>If animals are to remain in the vehicle.
Switching off tilt alarm sensor and 
interior motion sensor 
Press the   button on the remote con-
trol once again directly after locking.
The indicator lamp lights up briefly and 
then flashes continuously. The tilt alarm 
sensor and the interior motion sensor are 
switched off until the vehicle is unlocked 
and locked again.
Windows 
To prevent injuries, exercise care 
when closing the windows and keep 
them in your field of vision until they are 
shut.
When leaving the vehicle, always remove 
the ignition key and close the doors to pre-
vent children from operating the windows 
and injuring themselves etc.<
