Central locking system
The concept
The central locking system is ready for opera-
tion whenever 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: center armrest and glove com-
partment
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
The anti-theft system is also operated at the 
same time. It prevents the doors from being 
unlocked using the lock buttons or door han-
dles. 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 
page35.
Operating from inside
By means of the button for central locking, refer 
to page32.
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 page41.<
Unlocking
Press the   button.
The interior lamps, the courtesy lamps
* and the 
welcome lamps come on.

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 from the cargo bay beforehand to avoid 
water stains or soiling.
Do not place any objects on the retract-
able hardtop or on the luggage compart-
ment lid, otherwise they could fall during move-
ments 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 while the 
hardtop is opening or closing. 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 bay partition is folded 
down and engaged on both sides, refer to 
page117, otherwise it will not be possible 
to open the retractable hardtop.
>Do not place any objects next to or on the 
cargo bay partition and close the storage 
compartment on the left side of the cargo 
bay.
>Do not exceed the maximum loading height 
under the cargo bay partition; refer to the 
label in the cargo bay showing a line indicat-
ing the maximum height.
>Ensure that the luggage compartment lid is 
closed.
>The vehicle should be parked on fairly level 
ground. Excessive angle is indicated by a 
lamp.
