Central locking system
The concept The central locking system becomes active
when the driver's door is closed.
The system simultaneously engages and re‐
leases the locks on the following:
▷Doors.▷Compartment in the center armrest.▷Trunk lid.▷Fuel filler flap.
Operating from the outside
▷Via the remote control.▷Via the driver's door lock.▷Via the door handles.▷Via the button in the trunk lid.
The following takes place simultaneously
when locking/unlocking the vehicle via the re‐
mote control:
▷Depending on how the vehicle is equipped,
the theft protection is activated/deacti‐
vated. Theft protection prevents the doors
from being unlocked using the lock but‐
tons or the door opener.▷The welcome lamps, interior lamps and
courtesy lamps are switched on and off.▷The alarm system, refer to page 40, is
armed or disarmed.
Operating from the inside
Via the button for the central locking system.
If the vehicle has been locked from inside, the
fuel filler flap and the compartment in the cen‐
ter armrest remain unlocked.
If an accident of a certain severity occurs, the
central locking system unlocks automatically.
The hazard warning system and interior lamps
come on.

Danger of pinching even with pinch pro‐
tection
Even with the pinch protection system, check
that the window's closing path is clear; other‐
wise, the closing action may not stop in certain
situations, e.g., if thin objects are present.◀
No window accessories
Do not install any accessories in the
range of movement of the windows; otherwise,
the pinch protection system will be impaired.◀
Closing without the pinch protection system
Keep the closing path clear
Monitor the closing process and make
sure that the closing path of the window is clear; otherwise, injuries may result.◀
For example, if there is an external danger or if
ice on the windows prevents a window from
closing normally, proceed as follows:1.Pull the switch past the resistance point
and hold it there.
The pinch protection is limited and the
window reopens slightly if the closing force
exceeds a certain value.2.Pull the switch past the resistance point
again within approx. 4 seconds and hold it
there.
The window closes without pinch protec‐
tion.
Convertible top
General information The convertible top can be opened or closed
at speeds up to approx. 25 mph/40 km/h.
If the vehicle is accelerated above a speed of
approx. 30 mph/50 km/h while the convertible
top is being moved, the convertible top move‐
ment stops.
Tips about the convertible top:▷If possible, close the convertible top when
the vehicle is parked. A closed convertible
top protects it from weather-related dam‐
age and to some extent from theft.▷Event when the convertible top is closed,
only store valuables in the locked cargo
area.▷At higher speeds, vacuum produced in the
passenger compartment cause the
convertible top to begin to flatten. Increase
the amount of air via the automatic climate
control so that no vacuum is produced in
the vehicle.
Hints
The trunk lid cannot be opened if the
convertible top is not fully opened or closed.

the convertible top well longer than one
day while the top is still wet; otherwise,
damage could result due to moisture.▷When opening the convertible top, make
sure there are no foreign bodies on top of
it.▷The convertible top pivots up during open‐
ing and closing. When the top is moved,
e.g., in garages, make sure that there is a
minimum height of 79 inches/2 meters;
otherwise, it damages may result.▷Do not place any objects on the convertible
top, otherwise, they could fall and cause
damage or injuries.▷When the rollover protection system is ex‐
tended, do not under any circumstances
