Airbag system
WARNING
● If you do not wear a seat belt, if you lean
forward, or are not seated correctly while the
vehicle is in motion, you are at a greater risk
of injury if the side airbag system is triggered
in an accident.
● In order for the side airbags to provide their
maximum protection, the prescribed sitting
position must always be maintained with
seat belts fastened while travelling.
● In a side-on collision the side airbags will
not work if the sensors do not correctly meas-
ure the pressure increase on the interior of
the doors, due to air escaping through the
areas with holes or openings in the door pan-
el.
● Never drive if the interior door panels have
been removed or if the panels have not been
correctly fitted.
● Never drive the vehicle if the loudspeakers
in the door panels have been removed, un-
less the holes left by the loudspeakers have
been closed properly.
● Always check that the openings are closed
or covered if loudspeakers or other equip-
ment are fitted inside the door panels.
● Occupants of the outer seats must never
carry any objects or pets in the deployment
space between them and the airbags, or al-
low children or other passengers to travel in
this position. It is also important not to at-
tach any accessories (such as cup holders) to the doors. This would impair the protection
offered by the side airbags.
●
The built-in coat hooks should be used only
for lightweight clothing. Do not leave any
heavy or sharp-edged objects in the pockets.
● Great forces, such as hard blows or kicks,
must not be exerted upon the backrest bol-
ster because the system may be damaged. In
this case, the side airbags would not be trig-
gered.
● Under no circumstances should protective
covers be fitted over seats with side airbags
unless the covers have been approved for use
in your vehicle. Because the airbag deploys
from the side of the backrest, the use of con-
ventional seat covers would obstruct the side
airbag, seriously reducing the airbag's effec-
tiveness.
● Any damage to the original seat upholstery
or around the seams of the side airbag units
must be repaired immediately by a special-
ised workshop.
● The airbags provide protection for just one
accident; replace them once they have de-
ployed.
● Any work on the side airbag system or re-
moval and installation of the airbag compo-
nents for other repairs (such as removal of
the front seat) should only be performed by a
specialised workshop. Otherwise, faults may
occur during the airbag system operation.
● Do not attempt to modify components of
the airbag system in any way. Head-protection airbags*
Fig. 72
Location of head-protection airbags. The head-protection airbags are located on
both sides in the interior above the doors
››› Fig. 72 and are identified with the text
“AIRB AG”.
In c
onjunction with the seat belts, the head-
protection airbag system gives the vehicle
occupants additional protection for the head
and upper body in the event of a severe side
collision ››› .
WARNING
● In order for the head-protection airbags to
provide their maximum protection, the pre-
scribed sitting position must always be main-
tained with seat belts fastened while travel-
ling.
● For safety reasons, the curtain airbag must
be disabled in those vehicles fitted with a
screen dividing the interior of the vehicle. » 53

Safety
See your technical service to make this ad-

●
There must be no other persons, animals or
objects between the occupants of the outer
seats and the deployment space of the head-
protection airbags so that the head-protec-
tion airbag can deploy completely without re-
striction and provide the greatest possible
protection. Therefore, sun blinds which have
not been expressly approved for use in your
vehicle may not be attached to the side win-
dows
● The built-in coat hooks should be used only
for lightweight clothing. Do not leave any
heavy or sharp-edged objects in the pockets.
Please, do not hang the clothes on coat hang-
ers.
● The airbags provide protection for just one
accident; replace them once they have de-
ployed.
● Any work on the head-protection airbag
system or removal and installation of the air-
bag components for other repairs (such as re-
moval of the roof lining) should only be per-
formed by a specialised workshop. Other-
wise, faults may occur during the airbag sys-
tem operation.
● Do not attempt to modify components of
the airbag system in any way.
● The side and head airbags are managed
through sensors located in the interior of the
front doors. To ensure the correct operation of
the side and curtain airbags neither the
doors nor the door panels should be modified
in any way (e.g. fitting loudspeakers). If the front door is damaged, the airbag system
may not work correctly. All work carried out
on the front door must be done in a special-
ised workshop.

Operation
alarm is activated immediately on opening
the door).
● A door is opened.
● The bonnet is opened.
● The rear lid is opened.
● When the ignition is switched on with a
non-authorised key.
● When the vehicle battery is disconnected.
● Movement inside the vehicle (in vehicles
with interior monitoring ››› page 89).
● When the vehicle is towed (in vehicles with
anti-tow system ››› page 89 ).
● When the v
ehicle is raised (in vehicles with

).
● When the vehicle is transported on a ferry
or by rail (vehicles with an anti-tow system or
vehicle interior monitoring ››› page 89).
● When a trailer connected to the anti-theft
alarm system is disconnected.
How to turn OFF the alarm
Unlock the vehicle with the unlocking button
on the key or turn on the ignition with a valid
key. Note
● After 28 days, the indicator light will be
switched off to prevent the battery from ex-
hausting if the vehicle has been left parked for a long period of time. The alarm system
remains activated.
● If, after the audible warning goes off, an-
other monitored area is accessed (e.g. the
rear lid is opened after a door has been
opened), the alarm is triggered again.
● The anti-theft alarm is not activated when
the vehicle is locked from within using the
central locking button  .
● If the driver door is unlocked mechanically
with the key, only the driver door is unlocked,
the rest of the doors remain locked. Only
when the ignition has been turned on will the
other doors be available - but not unlocked -
and the central lock button will be activated.
● If the vehicle battery is run down or flat
then the anti-theft alarm will not operate cor-
rectly.
● 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 disconnected while the
alarm system is active. Vehicle interior monitoring and anti-
tow system*
It is a monitoring or control function incorpo-
rated in the anti-theft alarm* which detects
unauthorized vehicle entry by means of ultra-
sound.Activation
– It is automatically switched on when the
anti-theft alarm is activated.
Deactivation – Open the vehicle with the key, either me-
chanically or by pressing the  button on
the remote control. 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.
– Press the button  on the remote control
twice. 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,
88

Opening and closing
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/tilting sunroof open (partially or
completely).
● Movement of objects inside the vehicle,
such as loose papers, items hanging from
the rear vision mirror (air fresheners), etc. Note
● If the vehicle 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 vehicle 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 is 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). Deactivating the vehicle interior

protection button. When the vehicle is locked, the alarm will be
triggered if movements are detected in the
interior (e.g. by animals) or if the vehicle's in-
clination is changed (e.g. during transport).
You can prevent the alarm from being trig-gered accidentally by switching off the vehi-
cle interior monitoring and/or tow-away pro-
tection.
– To switch off the vehicle interior monitoring
and tow-away protection, switch off the ig-
nition and press button ››› Fig. 96 . The indi-

Lights and visibility
●
Always use your dipped beam head lights if
it is raining or if visibility is poor. WARNING
If the headlights are set too high and not
used correctly, there is a risk of dazzling or
distracting other road users. This could result
in a serious accident.
● Always make sure that the headlights are
correctly adjusted. Daytime driving light
The daytime driving lights consist of individu-
al lights, integrated in the front headlights.
With the daylight driving lights on, only these
lights switch on
››› .
The daytime driving lights switch on every
time the ignition is switched on, if the switch
is in positions  or , according to the level
of exterior lighting.
When the light switch is in position , a
light sensor automatically switches dipped
beam on and off (including the control and
instrument lighting) or the daytime driving
lights depending on the level of exterior
lighting. WARNING
● Never drive with daytime lights if the road
is not well lit due to weather or lighting con-
ditions. Daytime lights do not provide
enough light to illuminate the road properly
or be seen by other road users.
● The rear lights do not come on with the
daytime driving light. A vehicle which does
not have the rear lights on may not be visible
to other drivers in the darkness, in the case
of heavy rain or in conditions of poor visibili-
ty. Turn signal and main beam lever

Push the lever all the way down to turn off
the corresponding function.
Convenience turn signals
For the convenience turn signals, move the
lever as far as possible upwards or down-
wards and release the lever. The turn signal
will flash three times.
The convenience turn signals are activated
and deactivated in the Easy Connect system
via the  key and the
Setup function button
››› page 81 . In
v ehicles that do not have the correspond-
ing menu, this function can be deactivated in
a specialised workshop. WARNING
Improper or lack of use of the turn signals, or
forgetting to deactivate them can confuse
other road users. This could result in a seri-
ous accident.
● Always give warning when you are going to
change lane, overtake or when turning, acti-
vating the turn signal in good time.
● As soon as you have finished changing
lane, overtaking or turning, switch the turn
signal off. WARNING
Incorrect use of the headlights may cause ac-
cidents and serious injury, as the main beam
may distract or dazzle other drivers. Note
● The turn signal only works when the igni-
tion is switched on. The hazard warning
lights also work when the ignition is switch-
ed off.
● If a trailer turn signal malfunctions, the
control lamp will stop flashing (trailer turn
signals) and the vehicle turn signal will flash
at double speed.
● The main beam headlights can only be
sw
itched on if the dipped beam headlights
are already on. » 95

Main beam assist (Light Assist)
The main beam assist operates, within the
limits of the system and depending on the
environmental and traffic conditions, as of a
speed of 60 km/h (37 mph) when it switches
on automatically, and is then deactivated
again below 30 km/h (18 mph)

For the interval wipe
Intervals between wipes depend
on the vehicle's speed. The high-
er the vehicle speed the shorter
the intervals. Heated windscreen washer jets
The heating only thaws the frozen jets, it
does not thaw the water in the washer hoses.
The heated windscreen washer jets automati-
cally adjust the heat depending on the ambi-
ent temperature, when the ignition is switch-
ed on.
Headlight wash/wipe system
The headlight washers/wipers clean the
headlight lenses.
After the ignition is switched on, the first and
every fifth time the windscreen washer is
switched on, the headlights are also washed. Therefore, the windscreen wiper lever should
be pulled towards the steering wheel when
the dipped beam or main beam are on. Any
incrusted dirt (such as insects) should be
cleaned regularly (e.g. when refuelling).
To ensure the headlight washers work cor-
rectly in winter, any snow which has got into
the bumper jet supports should be cleaned
away. If necessary, remove snow with an anti-
icing spray.
Note
The wiper will try to wipe away any obstacles
that are on the windscreen. The wiper will
stop moving if the obstacle blocks its path.
Remove the obstacle and switch the wiper
back on again. Rain sensor*

Operation
Rain sensor modified behaviour
Possible causes of faults and mistaken read-
ings on the sensitive surface ››› Fig. 104 of
the r ain sen
sor include:
● Damaged blades: a film of water on the
damaged 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 windscreen wiper.
● Salt on roads: in winter, salt spread in the
roads may cause an extra long wipe when the
windscreen is almost dry.
● Dirt: dry dust, wax, coating on glass (Lotus
effect) or traces 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
will 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 switch on the wipers.
● If necessary, switch on the wipers manually
when water on the windscreen obstructs visi-
bility. Note
● Clean the sensitive surface of the rain sen-
sor regularly and check the blades for dam-
age ››› Fig. 104 (arrow).
● To r
emove wax and coatings, we recom-
mend a window cleaner containing alcohol. Rear vision mirror

of the mirror to face towards the rear. WARNING
In the event that an automatic anti-dazzle
rear vision mirror breaks, an electrolyte fluid
may leak. This could cause irritation to the
skin, eyes and respiratory organs. If you
come into contact with this liquid, it must be
rinsed with large quantities of water. If neces-
sary, get medial help. CAUTION
In the event that an automatic anti-dazzle
