– Unlock the vehicle and open the door in which you wish to acti-
vate the childproof lock.
– With the door open, rotate the groove in the door using the igni-
tion key, clockwise for the left hand side doors, and anti-clock-
wise for the right hand side doors ⇒ fig. 61 ⇒ fig. 62.
Deactivating the childproof lock
– Unlock the vehicle and open the door whose childproof lock you
want to deactivate.

tion key, clockwise for the right hand side doors, and anti-clock-
wise for the left hand side doors ⇒ fig. 61 ⇒ fig. 62.

WARNING
● An incorrect use of the keys can cause serious injuries.
● Never leave children or disabled persons in the vehicle. In case of
emergency, they may not be able to leave the vehicle or manage on their
own.
● An uncontrolled use of the key could start the engine or activate any
electric equipment (e.g. electric windows), causing risk of accident. The
doors can be locked using the remote control key. This could make the
aid difficult in an emergency situation.

WARNING
● An improper use of the key can cause serious injuries.
● Never leave children or disabled persons in the vehicle. In case of
emergency, they may not be able to leave the vehicle or manage on their
own.
● Never forget the keys inside the vehicle. Otherwise, this could result
in serious injuries, accidents or even the theft of your vehicle. Always
take the key with you when you leave the vehicle.
● An uncontrolled use of the key could start the engine or activate any
electric equipment (e.g. electric windows), causing risk of accident. The
vehicle can be locked when using the remote control key. This could com-
plicate the aid in case of emergency.
Note
● The remote control can be programmed by means of pressing the un-
locking button once; as a result, only the driver door will unlock. When the
button is pressed once more, all doors and the tailgate will be unlocked.
● The remote control functions only when you are in range ⇒ fig. 65 (red
area).
● If the vehicle is unlocked using the 

1 button, it will lock again auto-
matically if any of the doors or the tailgate are not opened within 30 sec-
onds after unlocking it. This function prevents the vehicle from remaining
unlocked if the unlock button is pressed by mistake.
● If the vehicle cannot be opened and closed using the remote control,
the remote control key will have to be re-synchronised ⇒ page 106.
Changing the battery
If the battery indicator does not flash when the buttons are pushed, the bat-
tery must be replaced.
CAUTION
The use of inappropriate batteries may damage the radio frequency remote
control. For this reason, always replace the dead battery with another of the
same size and power.
For the sake of the environment
Used batteries must be disposed of at an appropriate waste facility or
through an authorised service, given that their components can affect the
environment. 
Synchronising the remote control key
If it is not possible to unlock or lock the door with the remote
control, it should be re-synchronised.
– Press the 
⇒ fig. 64 button on the remote control.
– Then close the vehicle using the key bit within one minute.
It is possible that the vehicle could no longer be opened and closed with
the remote control if the button 
is repeatedly pressed outside of the ef-
fective range of the radio frequency remote control. The remote control key
will have to be resynchronised.
Spare remote control keys are available in your Authorised Service Centres,
where they must be matched to the locking system.
Up to eight remote control keys can be used. 

Anti-theft alarm system* Description of anti-theft alarm system*
The anti-theft alarm triggers if unauthorised movements are
detected around the vehicle.
The anti-theft alarm makes it more difficult to break into the vehicle or steal
it. Audible and visible alarms are triggered if the vehicle is opened using
the key, or if unauthorised access to the vehicle is forced.
The anti-theft alarm system is automatically connected on locking the vehi-
cle. The system is then primed.
When does the system trigger an alarm?
The system triggers an alarm if the following unauthorised actions are car-
ried out when the vehicle is locked:
● Opening the vehicle mechanically using the key and with the ignition off
● Opening a door
● Opening the bonnet
● Opening the tailgate
● Switching on the ignition
● Movements in the vehicle interior
● Undue manipulation of the alarm
● Battery handling
The acoustic signals sound and the turn signals flash for approx. 30 sec-
onds. This may be repeated up to 10 times depending on the country.
Opening the doors mechanically (emergency opening)
If the remote control function fails, you will have to use the key to unlock the
vehicle. This is done as follows: ●
Unfold the key by pressing the button shown by the (arrow).
● Use the lock on the driver door to unlock the vehicle. The anti-theft
alarm system remains active, but an alarm is not triggered immediately.
● Switch on the ignition within 15 seconds. When the ignition is switched
on, the electronic immobiliser recognises a valid vehicle key and deacti-
vates the anti-theft alarm system. If you do not switch on the ignition within
15 seconds, the alarm is triggered.
Opening all the doors in manual mode
In vehicles without alarm, when opening the driver door manually all the
doors are opened.
How to switch the alarm off
When the vehicle is unlocked via the unlocking button of the remote control
or when the key is inserted in the ignition lock.
Note
● If, after the alarm goes off, another monitored area is accessed (e.g. the
tailgate is opened after a door has been opened), the alarm is triggered
again.
● Vehicle monitoring remains active even if the battery is disconnected or
not working for any reason.
● The alarm is triggered immediately if one of the battery cables is discon-
nected while the alarm system is active. 
Volumetric sensor*
Monitoring or control function incorporated in the anti-theft
alarm* which detects unauthorized vehicle entry by means
of ultrasound.
The system consists of 3 sensors, 2 emitters and a receptor. 

Activation
–It is automatically turned on with the anti-theft alarm, when the
vehicle is locked mechanically with the key and when the but-
ton 
on the remote control is used.
Deactivation
– Press the button 
on the remote control twice. Only the volu-
metric sensor is deactivated. The alarm system remains activa-
ted.
WARNING
● The Safe security system remains deactivated if the volumetric sen-
sor is deactivated.
● For those vehicles in which a separation screen is fitted, the alarm
will not function correctly due to interference with the sensor.
Note
● If the alarm has been triggered by the volumetric sensor, this will be in-
dicated by a flashing of the indicator on the driver door. This flashing will be
different to that for an activated alarm. 

WARNING
● Always close the tailgate properly. Risk of accident or injury.
● Do not close the tailgate by pushing it down with your hand on the
rear window. The glass could smash. Risk of injury!
● Ensure the tailgate is locked after closing it. If not, it may open unex-
pectedly while driving.
● Never allow children to play in or around the vehicle. A locked vehicle
can be subjected to extremely high and low temperatures, depending on
the time of year, thus causing serious injuries/illness. It could even have
fatal consequences. Close and lock both the tailgate and all the other
doors when you are not using the vehicle.
● Closing the tailgate without observing and ensuring it is clear could
cause serious injury to you and to third parties. Make sure that no one is
in the path of the tailgate.
● Never drive with the tailgate open or half-closed, exhaust gases may
penetrate into the interior of the vehicle. Danger of poisoning!
● If you only open the tailgate, do not leave the key inside. The vehicle
will not be opened if the key is left inside.
 Emergency opening
This allows the vehicle to be opened if the central locking
does not operate (for example, if the battery is flat)

the emergency opening mechanism.
Opening the tailgate from inside the luggage compartment
