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.<

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.<

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:

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.

flashers flash and an acoustic signal
* sounds.<
Switching on radio readiness
Radio readiness is switched on by pressing the

It is not necessary to insert a remote control into 
the ignition lock, refer to page55.
Switching off the engine in cars with 
automatic transmission
The engine can only be switched off when the 
selector lever is in position P, refer to page56.
To switch the engine off when the selector lever 
is in position N, the remote control must be in 
the ignition lock.
Malfunction
Comfort Access may malfunction due to local 
radio waves. If this happens, open or close the 
vehicle via the buttons on the remote control or 
using the integrated key. To start the engine 
afterward, insert the remote control into the 
ignition lock.
Warning lamps
The warning lamp in the instrument 
cluster lights up when you attempt to 
start the engine: the engine cannot 
be started. The remote control is not inside the 
vehicle or is malfunctioning.
Take the remote control with you inside the 
vehicle or have it checked. If necessary, insert 
another remote control into the ignition lock.
The warning lamp in the instrument 
cluster lights up while the engine is 
running: the remote control is no 
longer inside the vehicle. After the engine is 
switched off, the engine can only be restarted 
within approx. 10 seconds. 

Opening and closing

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 
area.
>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 trunk lid, 
and in particular do not attach magnetic 
racks.
>When the retractable hardtop is operated, 
the trunk lid swings back and up. Before 
operating the retractable hardtop, ensure 
that there is enough clearance, 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 area. If necessary, remove items 
from the cargo area beforehand to avoid 
water stains or soiling.
Do not place any objects on the retract-
able hardtop or on the trunk lid; other-
wise, they could fall during movements of the 
retractable hardtop and cause damage or injury.
Never move the retractable hardtop when the 
rollover protection system is in the activated 
position.
Driving when the hardtop is not fully opened or 
closed may result in damage or injury.
Do not reach into the mechanism during the 
opening or closing procedure. Keep children 
away from the swiveling area of the retractable 
hardtop.<
The retractable hardtop cannot be moved 
at temperatures below + 147/–106. A 
message appears on the Control Display.<
The retractable hardtop can only be 
opened and closed when the vehicle is 
stationary. To avoid causing damage, do not 
drive off until the hardtop has stopped mov-
ing.<
Before opening and closing
>Comply with the safety precautions 
described above.
>Ensure that the cargo area partition is 
folded down and engaged on both sides, 
refer to page110; otherwise, it will not be 
possible to open the retractable hardtop.
>Do not place any objects next to or on the 
cargo area partition and close the storage 
compartment on the left side of the cargo 
area.
>Do not exceed the maximum loading height 
under the cargo area partition; refer to the 
label in the cargo area showing a line indi-
cating the maximum height.
>Ensure that the trunk lid is closed.
>The vehicle should be parked on fairly level 
ground. Excessive angle is indicated by a 
lamp.
