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/tailgate
>Fuel filler door
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 interior lamps and the door's courtesy
lamps
* are also 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.

desired, by tapping or pulling the lever when road and traffic conditions permit. It is not pos-
sible to resume a stored speed.
Radar sensor
The sensor's ability to detect vehicles ahead
may be restricted as a result of heavy rain, dirt,
snow or ice. If necessary, clean the radar sensor
located in the front bumper, see arrow. Be sure
to use particular care when removing any layers
of snow or ice from the sensor.
When the radar sensor is not properly posi-
tioned, active cruise control cannot be activated
at all.
Malfunction
The warning lamp comes on when
the system has failed. A message
appears on the Control Display. You
can find more information starting on page81.
System limitations
Always remember that the range and abil-
ity of the system does have physical limi-
tations. It will not apply the brakes or decelerate
your vehicle when there is a slow-moving vehi-
cle, stopped vehicle or stationary object ahead
of you, as for example, at a traffic light or a
parked vehicle. Also, the system does not react to oncoming traffic, pedestrians or other types
of potential traffic such as a rider on horseback.
It is also possible that the system may not
detect smaller moving objects such as motor-
cycles or bicycles. Be especially alert when
encountering any of these situations as the sys-
tem will neither automatically brake, nor provide
