This function is independent of the vehicle
electronic opening and locking systems. It
only affects rear doors. It can only be activa-
ted and deactivated manually, as described
below:
Activating the childproof lock

If the v
ehicle battery is run down or flat
then the anti-theft alarm will not operate cor-
rectly.

stem* It is a monitoring or control function incorpo-

at
ed in the anti-thef

t alarm* which detects
unauthorised vehicle entry by means of ultra-
sound.
Activation
– It is automatically switched on when the
anti-theft al

arm is activated.
Deactivation – Open the vehicle with the key, either me-
chanic

ally or by pressing the  button on
the r emot
e c
ontrol. The time period from
when the door is opened until the key is in-
serted in the contact should not exceed 15
seconds, otherwise the alarm will be trig-
gered. –
Pres
s the button  on the remote control
tw ic
e.
The volumetric sensor and tilt sen-
sors will be deactivated. The alarm system
remains activated.
The vehicle interior monitoring and the anti-
tow system are automatically switched on
again next time the vehicle is locked.
The vehicle interior monitoring and anti-tow
sensor (tilt sensor) are automatically switch-
ed on when the anti-theft alarm is switched
on. In order to activate it, all the doors and
the rear lid must be closed.
If you wish to switch off the vehicle interior
monitoring and the anti-tow system, it must
be done each time that the vehicle is locked;
if not, they will be automatically switched on.
The vehicle interior monitoring and the anti-
tow system should be switched off if animals
are left inside the locked vehicle (otherwise,
their movements will trigger the alarm) or
when, for example, the vehicle is transported
or has to be towed with only one axle on the
ground.
False alarms
Interior monitoring will only operate correctly
if the vehicle is completely closed. Please ob-
serve related legal requirements.
The following cases may cause a false alarm: ● Open windows (partially or fully). ●
Panoramic/ti lting sunroof open (partially or
completely).
● Movement of objects inside the vehicle,
such a
s loose papers, items hanging from
the rear vision mirror (air fresheners), etc. Note
● If the v

ehicle is relocked and the alarm is
activated without the volumetric sensor func-
tion, relocking will activate the alarm with all
its functions, except the volumetric sensor.
This function is reactivated when the alarm is
switched on again, unless it is deliberately
switched off.
● If the alarm has been triggered by the volu-
metric sensor
, this will be indicated by a
flashing of the warning lamp on the driver
door when the vehicle is opened. The flash is
different to the flash indicating the alarm is
activated.
● The vibration of a mobile phone left inside
the vehic
le may cause the vehicle interior
monitoring alarm to trigger, as both sensors
react to movements and shakes inside the ve-
hicle.
● If on activating the alarm, any door or the
rear lid i
s open, only the alarm will be activa-
ted. The vehicle interior monitoring and the
anti-tow system will only be activated once
all the doors are closed (including the rear
lid). 125

lowing conditions may prevent the
main beam headlight control from turning off
the headlights in time or from turning off al-
together:
● In poorly lit towns with highly reflective
signs. ●
Other in
suffic

pedestrians or cyclists).
● On tight bends and steep slopes (bumps)
and when oncoming
vehicles are partially ob-

rail in the centre of the road.
● If the camera is damaged or the power sup-

● In fog, snow and heavy rain.
● With dust and sand turbulence.
● With loose gravel in the field of vision of
the camera.
● When the fiel

d of vision of the camera is
mist
ed up, dirty or covered by stickers, snow,
ice, etc. WARNING
The convenience features of the main beam
as s

ist should not encourage the taking of
risks. The system is not a replacement for
driver concentration.
● You are always in control of the main beam

● It is possible that the main beam headlight
contro

Rain sensor modified behaviour
P o
s
sible causes of faults and mistaken read-
ings on the sensitive surface ››› Fig. 144 of
the rain sensor include:
● Damaged blades: a film of water on the
damag
ed blades may lengthen the activation
time, reduce the washing intervals or result
in a fast and continuous wipe.
● Insects: insects on the sensor may trigger
the winds
creen wiper.
● Salt on roads: in winter, salt spread in the
roa
ds may cause an extra long wipe when the
windscreen is almost dry.
● Dirt: dry dust, wax, coating on glass (Lotus
effect) or trac
es of detergent (car wash) may
reduce the effectiveness of the rain sensor or
make it react more slowly, later or not at all.
● Cracked windscreen: the impact of a stone
wil
l trigger a single wipe cycle with the rain
sensor on. Next the rain sensor detects the
reduction in the sensitive surface area and
adapts accordingly. The behaviour of the sen-
sor will vary with the size of the damage
caused by the stone. WARNING
The rain sensor may not detect enough rain
to sw it

ch on the wipers.
● If necessary, switch on the wipers manually
when water on the w
indscreen obstructs visi-
bility. Note
● Cle

an the sensitive surface of the rain sen-
sor regularly and check the blades for dam-
age ››› Fig. 144 (arrow).
● To remove wax and coatings, we recom-
mend a window c
leaner containing alcohol. Mirror

In the event that an automatic anti-dazzle
