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

page

Operating from inside

By means of the button for central locking, refer
to page

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 page

Unlocking

Press the

button.

The interior lamps, the courtesy lamps

and the

welcome lamps come on.

Setting unlocking characteristics

You can set whether only the driver's door or
the entire vehicle is to be unlocked when the
button is pressed for the first time.
