Central locking system Door locks – from outside The conceptThe central locking system is ready for 
operation whenever the driver's door is 
closed. The system engages and re-
leases the locks on the
>doors
>luggage compartment lid
>fuel filler door. 
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 release handles remain 
locked. The alarm system
* is also 
armed or disarmed.
In the event of an accident, the central 
locking system unlocks automatically. 
In addition, the hazard warning flashers 
and interior lamps come on.
Using the keyOne turn of the key in the door lock 
opens only the driver's door, a second 
turn of the key opens the passenger 
door, the luggage compartment lid and 
the fuel filler door. 
You can have a confirmation mes-
sage set to inform you that the car 
has been properly locked.<
You will find additional information on 
the alarm system on page 42.460de006
Convenience operating modeYou can also operate the electric win-
dows and sliding/tilt sunroof via the 
door lock.
>To open: With the door closed, turn 
the key to the "Unlock" position and 
hold it.
>To close: With the door closed, turn 
the key to the "Lock" position and 
hold it.
Watch during the closing process 
to make sure that nobody is in-
jured accidentally. Letting go of the key 
stops the operation.
Turn the key all the way to the extreme 
left or right to unlock/lock the door.

Door locks – from inside Use this button to operate the central 
locking system when the doors are 
closed. The doors and luggage com-
partment lid are unlocked or locked 
only. The anti-theft alarm system is not 
activated.
After opening the driver's door by acti-
vating the remote control once, the 
front passenger door can also be 
opened by pressing the button. When 
the driver's door is closed, it is auto-
matically locked.
If you desire, the central locking 
system will secure the locks as 
soon as you start to drive. This can be 
adjusted to be key-specific.<460us007
To unlock and open the doors>Either unlock the doors together with 
the button for the central locking sys-
tem 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.
Doors locked from outside can be 
opened from inside by first press-
ing the button and then pulling a re-
lease handle twice.<
To engage locks>Either use the central locking button 
to lock all doors at once, or
>press down the individual door lock 
buttons. The fuel filler door then re-
mains unlocked. As an added design 
feature to prevent the driver from be-
ing inadvertently locked out of the ve-
hicle, the driver's door 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 rea-
son, take the vehicle's keys with you so 
that the vehicle can be opened again 
from the outside at any time.<
