Central locking system Opening and closing Ð from the outside The conceptThe central locking system is ready for 
operation whenever the driver's door 
is closed. The system engages and 
releases the locks on the
>doors
>luggage compartment lid
>fuel filler door 
>glove compartment
at the same time.
The central locking system can be 
operated
>from outside via the door lock and 
using the remote control
>from inside by pressing a button.
Activating it from inside does not lock 
the fuel filler door (see page 38). When 
the system is actuated from the 
outside, the anti-theft system is acti-
vated simultaneously. Both the door 
locks and the safety lock buttons 
remain locked. The alarm system is also 
armed or disarmed.
The central locking system unlocks 
automatically in the event of an acci-
dent. In addition, the hazard warning 
flashers and interior lamps come on.
Using the keyTurning the key once in the driver-side 
door will unlock only the driver's door. 
Turning the key a second time will 
unlock the passenger-side door, the 
luggage compartment lid, the fuel filler 
door and the glove compartment.
You can have a signal set as an 
acknowledgment message that 
the vehicle is closed correctly.<460de006
Convenience operationYou can also operate the power 
windows and the fully automatic 
convertible top from the door lock.
>To open: with the door closed, hold 
the key in the "Unlock" position.
>To close: with the door closed, turn 
the key to the "Lock" position and 
hold it.
Watch during the closing process 
to be sure that no one is injured. 
Releasing the key stops the operation.
Turn the key to the extreme left or right 
to unlock/lock the door.

Opening and closing Ð from the inside Use this button to operate the central 
locking system whenever the doors are 
closed. The doors and luggage 
compartment lid are unlocked or locked 
only. The anti-theft alarm system is not 
activated.
If only the driver's door was 
unlocked from the outside and you 
press the button, then the passenger-
side door, the luggage compartment lid, 
the fuel filler door and the glove 
compartment will unlock if the driver's 
door is open. 
The driver's door will be locked if it is 
closed.<
If you desire, the central locking 
system will secure the locks as 460us007
soon as you start to drive. This can be 
adjusted to be key-specific.Either unlock the doors at the same 
time using the button for the central 
locking system and then pull each of 
the release handles above the 
armrests, 
or
>pull the release handle for each door 
twice: the first pull unlocks the door, 
and the second one opens it.
To engage the locks>Either use the central locking button 
to lock both doors at once, 
or
>press the individual safety lock 
buttons down. To prevent the driver 
from being inadvertently locked out 
of the vehicle, the driver's door safety 
lock button will not engage as long as 
the door is open.
Children might be able to lock the 
doors from the inside. For this 
reason, always take the vehicle's keys 
with you so that the vehicle can be 
opened again from the outside at any 
time.<
