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
>Luggage compartment lid
>Fuel filler door
>Convertible: glove compartment
Operating from outside
>Via the remote control>Via the door lock
*
>In cars with convenient access*, via the 
handles on the driver's and front passen-
ger's 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 luggage compartment lid must be 
closed and the cargo bay partition must be 
folded down and engaged on both sides. Refer 
also to page39.<
Unlocking

pressing the   button on the remote control, 
refer to page28. The lid is locked and moni-
tored again as soon as you close it.

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

Convenient access*
Convenient access enables you to enter your 
vehicle without needing to hold the remote con-
trol 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.
Convenient access supports the following 
functions:
>Unlocking/locking the vehicle
>Unlocking the luggage compartment lid 
separately
>Engine starting
>Convenient closure
Functional requirement
>The vehicle or the luggage compartment 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 
convenient access or pressing the buttons on 
the remote control to carry out the functions 
mentioned above. You should therefore first 
familiarize yourself with the instructions on 
opening and closing starting on page26.
Special features regarding the use of conve-
nient access are described below.
If you notice a brief delay while opening or 
closing windows, the glass roof or retract-
able hardtop, the system is checking whether a remote control is inside the vehicle. Please 
repeat the opening or closing procedure, if nec-
essary.<

Convertible: retractable 
hardtop
The retractable hardtop combines reliable 
weather protection with simple and convenient 
operation.
The following tips will enhance your driving 
pleasure in your convertible:
>It is advisable that you close the retractable 
hardtop when you park the vehicle. Not only 
does the closed hardtop protect the vehicle 
interior against unanticipated weather dam-
age, it also offers theft protection. However, 
even when the hardtop is closed, valuables 
should only be stored in the locked cargo 
bay.
>Do not attach roof rack systems to the 
retractable hardtop, and in particular do not 
attach magnetic racks.
>Do not attach rack systems to the luggage 
compartment lid, and in particular do not 
attach magnetic racks.
>When the retractable hardtop is operated, 
the luggage compartment lid swings back 
and up. Before operating the retractable 
hardtop, ensure that there is enough clear-
ance, e.g. when parked in front of a wall.
>If you open the hardtop while it is wet, e.g. 
after driving in the rain, water may drip into 
the cargo bay. If necessary, remove items
