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 
vehicle. The system is then primed.
When does the system trigger an alarm?
The system triggers an alarm if the following unauthorised actions are carried 
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 seconds. 
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 deactivates 
the anti-theft alarm system. If you do not switch on the ignition within 15 
seconds, the alarm is triggered.
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.

a factory-fitted  towing bracket, the rear fog light on the vehicle will automati-
cally be switched off.•The use of the lighting described here is subject to the relevant statutory 
requirements.•Depending on weather conditions (very cold or wet), the front and tail 
lights and the turn signals may be temporarily misted. This has no influence 
on the useful life of the lighting system. The lights will soon demist when they 
are switched on.Automatic lighting*Activation
– Rotate the switch to the position “Auto”, this indication will light  up. Deactivation
– Turn the light switch to 0.
Automatic lighting
If automatic headlight control is switched on, dipped beam headlights are 
automatically switched on by a photosensor if you drive into a tunnel, for 
example.
The rain sensor switches on the dipped beam headlights when the wind-
screen wipers have been operating continuously for a few seconds and it 
switches the lights off when the continuous or intermittent wipe is switched 
off for some minutes ⇒
page 132.
When the automatic dipped light control is connected but the dipped lights 
are off, the warning lamp

 lights up on the light control  ⇒fig. 74. If the 
automatic control switches on the dipped lights, the instrument and control 
lighting is also switched on.
WARNING
•Even if the automatic headlight control is switched on, the dipped 
headlights will not be switched on with fog. Therefore, the dipped beam 
must be switched on manually.Note
•For those vehicles with the automatic headlight system, when the key is 
removed from the ignition, the acoustic signal will only sound if the light 
control is in the position

cause disruptions or faults in the automatic lighting system.•To avoid damage to the tail lights, the lights mounted on the tailgate go 
off when the tailgate is opened (depending on the country).Daytime lights*
The daytime light reduces the risk of accidents by increasing 
the visibility of the vehicle. The daytime running lights are 
enabled automatically when the ignition is switched on. It is 
automatically switched off when the side lights are turned on.Daytime lights (halogen lamps)

It is not possible to switch the daytime lights on or off. Please contact a 
specialised workshop if you wish to deactivate the lights.
Daytime lights (bi-xenon lamps)

lighting (bi-xenon headlamps)
If the dipped light control
 and the daytime lighting are activated at the same 
time, the dipped lights and the instrument panel lighting will automatically 
come on as required (e.g. on entering a tunnel) and the daytime lights will go 
off. When the automatic dipped light control switches off the dipped lights 
(e.g. on coming out of the tunnel), the daytime lights come back on.
Activating the daytime lights

Dynamic cornering lights* (AFS)
The 
dynamic cornering lights only operate if the vehicle is travelling at more 
than 10 km/h and the dipped headlights are on. When taking a bend, the 
road is illuminated better with directional gas discharge bulbs than with 
conventional fixed headlights.
A fault in the system is indicated via the flashing of the control lamp 
  on the 
instrument panel. At the same time,  a text message with information or 
instructions to perform necessary operations may appear on the instrument 
panel display. Take the vehicle to a specialised workshop and have the fault 
repaired.
If the control bulb 
  lights up on the instrument panel but all the bulbs are 
operating correctly ⇒ page 272, there may still be a fault in the dynamic 
curve lighting system (AFS). Take the vehicle to a specialised workshop and 
have the fault repaired.

headlights will not be switched on in fog. They should be switched on 
manually using the light switch. The driver is personally responsible for the 
correct use of lights in all situations. “Automatic headlight control” is 
merely a system to support the driver. Where necessary, switch on the 
lights manually using the light switch.Fog lights with cornering function*When the turn signal is switched on to turn or on very tight bends, the right 
or left fog lamp automatically comes on to function as a  cornering light. The 
cornering light only operates if the dipped lights are on.
