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
>Trunk lid
>Fuel filler flap
>Convertible: glove compartment
Operating from outside
>Via the remote control>Via the door lock
*
>In cars with Comfort Access*, via the han-
dles on the driver's and front passenger 
doors
In addition, if the remote control is used, the 
welcome lamps, interior lamps and the door's 
courtesy lamps
* are switched on or off. The 
alarm system
* is also armed or disarmed.
For further details of the alarm system,
 refer to 
page32.
Operating from inside
By means of the button for central locking, refer 
to page30.
In the event of a sufficiently severe accident, the 
central locking system unlocks automatically. In 
addition, the hazard warning flashers and inte-
rior lamps come on.
Opening and closing:
Using the remote control
Persons or animals in a parked vehicle 
could lock the doors from the inside. You 
should therefore take the remote control with 
you when you leave the vehicle so that the latter 
can be opened from outside.<
Convertible: to operate the retractable 
hardtop with the remote control, the 
doors and trunk lid must be closed and the 
cargo area partition must be folded down and 
engaged on both sides. Refer also to page38.<
Unlocking
Press the   button.
The interior lamps, the courtesy lamps
* and the 
welcome lamps come on.
Setting unlocking characteristics
You can set whether only the driver's door or 
the entire vehicle is to be unlocked when the 
button is pressed for the first time.

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
*.
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.
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
Functional requirement
>The vehicle or the trunk 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.
Comparison to the standard remote 
control
In general, there is no difference between using 
Comfort Access or pressing the buttons on the 
remote control to carry out the functions men-
tioned above. You should therefore first famil-
iarize yourself with the instructions on opening 
and closing starting on page26.
Special features regarding the use of Comfort 
Access are described below.
