2 remote control keys
In certain European markets, vehicles with alarm are equipped with 2 re-
mote control keys.
WARNING
● Always take the key with you when leaving the vehicle, even if you
only intend to be gone for a short time. This is particularly important if
there are children in the vehicle, as they might otherwise be able to start
the engine or use power-operated equipment (e.g. the electric windows),
which could cause injuries.
● Wait for the vehicle to come to a standstill before removing the igni-
tion key from the lock! Otherwise, the steering lock could engage sud-
denly, causing an accident.

Unlocking and locking
● This will lock all the doors and the rear lid.
● The interior lights are switched off, provided the light switch is in the
courtesy light position.
● The windows and the sunroof* will close as the key is held in the locking
position.
● The anti-theft security system will be enabled immediately.
Locking the vehicle without activating the anti-theft security system
With the anti-theft security system enabled, it is more difficult to break into
the vehicle. If the anti-theft security system has been enabled, the inside
door handles and the central locking switch will not work ⇒ 
.
If you are leaving passengers in the vehicle while it is parked, it is possible
to lock the vehicle without activating the anti-theft security system.
To do so, turn the key in the driver door twice in quick succession to posi-
tion B
⇒ Fig. 70.
WARNING
Do not leave anyone (especially children) in the vehicle if it is locked from
the outside and the anti-theft security system is enabled, as the doors
and windows cannot then be opened from the inside. Locked doors could
delay assistance in an emergency, potentially putting lives at risk.
CAUTION
If the driver door is locked using the key while open, the vehicle will be au-
tomatically immobilised and the alarm triggered.
Note
● Please note that when the vehicle is locked without activating the anti-
theft mechanism, the anti-theft alarm* remains operative. You should there-
fore switch off the interior monitoring* before locking the vehicle, as other-
wise the alarm* could be triggered unintentionally.
● The driver door cannot be locked using the central locking system when
it is still open. The door must be locked separately after it has been closed.
This helps to prevent you from being locked out of the vehicle. 
Central locking switch
The central locking system can be enabled from inside the
vehicle using the central locking switch on the driver door.

.
Please note the following when using the central locking switch to lock your
vehicle:
● The doors and the rear lid cannot be opened from the outside (for secur-
ity reasons, e.g. when stopped at traffic lights).
● You can open the doors individually from the inside by pulling the inside
door handle.
● When the driver door is open, it cannot be locked by pressing the central
locking switch and then closing the door. This helps to prevent you from be-
ing locked out of the vehicle. The door has to be locked separately after it
has been closed.
● In the event of an accident in which the airbags inflate, doors locked
from the inside will be automatically unlocked to facilitate access and assis-
tance.
WARNING
The central locking switch is still operative when the ignition is switched
off. This switch can be used to automatically lock all the doors and the
rear lid. However, since this makes it difficult to enter the vehicle from
the outside, you should never leave children unattended in the vehicle.
Locked doors could delay assistance in an emergency, potentially putting
lives at risk.
Note
The central locking switch inside the vehicle will not be operative if the anti-
theft mechanism has been enabled. Security central locking*
The security central locking feature allows you to only unlock
the driver door and the tank flap. All other doors and the
rear lid remain locked.

– Turn the key once to the unlock position, or press the unlock
button on the remote control once.
Unlocking all the doors, the rear lid and the tank flap

– Turn the key twice within five seconds, or press the unlock but-
ton on the remote control twice within five seconds.
The security system and the anti-theft alarm* are immediately disabled if
you unlock only the driver door, without unlocking the other doors
⇒  page 110. 

Remote control key Description
The remote control key will lock and unlock the vehicle with-
out having to insert the key in the lock. The following functions are available:
● Locking and unlocking the vehicle
● Unlocking the rear lid
All the turn signals will flash as confirmation when the vehicle is locked or
unlocked. Furthermore, the interior lights will automatically light up when
the vehicle is unlocked and go out when the vehicle is locked, provided that
the switches are in the courtesy light position.
The remote control transmitter and the battery are integrated into the han-
dle of the key. The receiver is in the interior of the vehicle. The maximum
range depends on different circumstances. The range is reduced when the
battery starts to lose power.
The remote control incorporates a foldaway key that can be used to manual-
ly lock or unlock the vehicle, as well as to start the engine. If the receiver has been repaired or replaced, or if a replacement key is
used, the system will need re-programming by a specialised workshop. Only
then will you be able use the remote control again.
The remote control meets all relevant authorisation requirements and has
been approved by the Federal Approvals Office for Telecommunications of
the Federal Republic of Germany. All components are marked in accordance
with the current legal requirements. This certification forms the basis for of-
ficial approval for use in other countries.
Note
● The remote control is automatically disabled when the ignition is switch-
ed on.
● The function of the remote control may be impaired by interference from
other nearby radio signals (e.g. from a mobile phone or TV transmitter) if
these are in the same frequency range. 

Unlocking and locking
LED
When the vehicle is locked, the LED on the top of the driver door trim will
flash rapidly for about 30 seconds and then continue flashing slowly. This is
to indicate that the anti-theft alarm system (including the interior monitor-
ing and tow-away protection ) is operative. If the LED lights up continuously
for about 30 seconds when the vehicle is locked instead of flashing, this
means the alarm system is not working properly.
Note
● To make sure that the alarm is fully operative when leaving the vehicle,
briefly check that all the doors and windows and the sunroof* are closed.
● The alarm is triggered immediately if one of the battery cables is discon-
nected while the alarm system is enabled. 

function
The dipped beam headlights will only work with the ignition on. The head-
lights are automatically switched to side lights after the ignition has been

● Depending on weather conditions (cold or wet), the front lights, the fog
lights, the tail lights and the turn signals may be temporarily misted. This
has no influence on the useful life of the lighting system. By switching on
the lights, the area through which the beam of light is projected will quickly
be demisted. However, the edges may continue to be misted. 
