Display of the locking
The turn signal lights flash once to confirm that the vehicle has been correctly
locked.
If the vehicle is locked by pressing the button 3 and some doors or the boot lid
are not closed, the turn signal lights flash only after closing. WARNING
If the vehicle is locked from the outside and the safe securing system is acti-
vated, there must not be any person in the vehicle as it is then not possible to
open either a door or a window from the inside. The locked doors make it
more difficult for rescuers to get into the vehicle in an emergency - hazard! Note
● Operate the radio remote control only when the doors and boot lid are closed
and you have visual contact with the vehicle.
● Once in the car, you must not press the lock button of the radio remote con-
trol before inserting the key into the ignition lock in order to avoid the car being
inadvertently locked and the alarm system being switched on. Should this happen,
press the unlock button of the radio remote control. Synchronisation of the remote control If the vehicle cannot be unlocked by actuating the remote control system then it
is possible that the code in the key and the control unit in the vehicle are no lon-
ger synchronised. This can occur when the buttons on the radio-operated key are
actuated a number of times outside of the operative range of the equipment or
the battery on the remote control was replaced.
This means it is necessary to synchronise the code as follows:
● press any button on the remote control;
● pressing of the button means that the door will unlock with the key within 1
minute.
Anti-theft alarm system
Description The anti-theft alarm system increases the level of protection against people seek-
ing to break into the vehicle. The system triggers audible and visual warning sig-
nals if an attempt is made to break into the vehicle.
How is the alarm system activated?
The anti-theft alarm system is activated automatically when the vehicle is locked
with the key on the driver's door or by using the radio remote control. It is activa-
ted 30 seconds after locking the door.
How is the alarm system deactivated?
The anti-theft alarm system is deactivated if the vehicle is unlocked by only using
the radio remote control. The anti-theft alarm system is reactivated if the vehicle
is not opened within 30 seconds after transmitting the radio signal.
Once you unlock the vehicle by inserting the key into the driver door you then
have to insert the key into the ignition lock and switch the ignition on within 15
seconds after opening the door in order to deactivate the anti-theft alarm system.
The alarm will be triggered if you do not switch on the ignition within 15 seconds.
When is the alarm triggered?
The following security areas of the locked vehicle are monitored:
● Bonnet,
● Boot lid, £ 37

●
Doors,
● Ignition lock,
● Vehicle inclination ⇒ page 38,
● Vehicle interior⇒ page 38,
● A drop in voltage of the on-board power supply,
● Socket of the factory-fitted towing device.
An alarm is immediately triggered if either of the two battery terminals is discon-
nected while the anti-theft alarm system is activated.
How is the alarm switched off?
You switch the alarm off if you unlock the vehicle with the radio remote control or
if you switch the ignition on. Note
● The working life of the alarm siren is 6 years. More detailed information is
available by a specialist garage.
● Before leaving the car, check that all the doors, windows and the electric slid-
ing/tilting roof are properly closed in order to ensure that the anti-theft alarm sys-
tem is fully operational.
● Coding of the radio remote control and the receiver unit precludes the use of
the radio remote control from other vehicles.

Rain lights
If you switch on the windscreen wipe in the operation rain sensor for longer than
10 seconds or in the operation permanent wipe (position
2 or 3) ⇒ page 53
switching on for longer than 15 seconds, the side lights and low beam are switch-
ed on automatically. The light switches off if the windscreen wipe is in operation
rain sensor for more than around 4 minutes or is not switched on in the operation
permanent wipe. WARNING
The automatic light control only operates as a support. The driver is not re-
leased from his responsibility to inspect the light and if necessary to switch on
the light depending on the light conditions. The light sensor cannot detect for
example rain or snow. For these conditions we recommend to switch on the
low beam ! Note
● Do not affix any stickers in front of the light sensor, so that you do not impair
its function or put it out of operation.
● The same principles as for using the automatic light control also apply to the
