Airbag system
Side airbags* Fig. 15
Side airbag in driver seat. Fig. 16
Inflated side airbag on left side of ve-
hicle. The side airbags are located in the backrest
cushions of the driver seat
››› Fig. 15 and the
fr ont
passenger seat and the rear side air-
bags are mounted in the rear wheel housing.
The locations are identified by the text “AIR-
BAG” in the upper region of the backrests
and in the rear wheel housing lining. In conjunction with the seat belts, the side
airbag system gives the front seat occupants
additional protection for the upper body in
the event of a severe side collision.
In a side collision, the side airbags reduce
the risk of injury to passengers on the front
seats to the areas of the body facing the im-
pact. In addition to their normal function of
protecting the occupants in a collision, the
seat belts also hold the passengers in the
front seats and the outer rear seats in a posi-
tion where these airbags can provide maxi-
mum protection.
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.
● 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 is trig-
gered from the side of the backrest, the use
of non-approved seat covers would obstruct
the side airbag, seriously reducing the air-
bag's effectiveness ››› page 147.
● 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.
● 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 (head) airbags neither » 21

the doors nor the door panels should be
modified in any way (e.g. fitting loudspeak-
ers). If the front door is damaged, the airbag
system may not work correctly. All work car-
ried out on the front door must be done in a
specialised workshop.
●
In a side collision, the side airbags will not
work, if the sensors do not correctly measure
the pressure increase on the interior of the
doors, due to air escaping through the areas
with holes or openings in the door panel.
● Never drive the vehicle if the interior panels
have been removed.
● 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 additional loudspeakers or other
equipment are fitted inside the door panels.
● Any work carried out to the doors should be
made in an authorised specialised workshop. Head-protection airbags*

Location of head-protection airbags
on the left side of the vehicle Fig. 18
Deployed head-protection airbags. The head-protection airbags are located on
both sides in the interior above the doors
››› Fig. 17 and are identified with the text
“AIRB AG”.
In c
onjunction with the seat belts, the head-
protection airbag system gives the 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.
See a Technical Service to make this adjust-
ment.
● 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 ››› page 147.
● The b ui

lt-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. 22

Airbag system
●
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. Deactivating airbags

Opening and closing
● The turn signal light will flash once on clos-
ing and activating the alarm.
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.
● A door is opened.
● Opening the bonnet.
● The rear lid is opened.
● Ignition switched on with a non-validated
key.
● Movements in the driving compartment
(vehicles with interior monitoring).
● Undue manipulation of the alarm.
● Battery handling.
The acoustic signals sound and the turn sig-
nals flash for approx. 30 seconds. This cycle
may be repeated up to 10 times depending
on the country.
Opening the doors mechanically (emergency
opening)
If the radio frequency remote control function
fails, you will have to use the key to unlock
the vehicle. This is done as follows: ●
Use the lock on the driver door to unlock
the vehicle. The anti-theft alarm system re-
mains active, but an alarm is not triggered
immediately.
● Switch on the ignition within 15 seconds.
When the ignition is switched on, the elec-
tronic immobiliser recognises a valid vehicle
key and deactivates the anti-theft alarm sys-
tem. If you do not switch on the ignition with-
in 15 seconds, the alarm is triggered (in cer-
tain markets, such as the Netherlands, there
is no 15-second waiting time and the alarm
is activated immediately after opening the
door).
Opening all the doors in manual mode
In vehicles without an alarm, when opening
the driver door manually, all doors are
opened.
How to switch the alarm off
When the vehicle is unlocked via the unlock-
ing button of the radio frequency remote con-
trol or when the key is inserted in the ignition
lock. Note
● After 28 days, the indicator light will be
switched off to prevent the battery from
draining if the vehicle has been left parked
for a long period of time. The alarm system
remains activated. ●
If, after the audible warning turns off, an-
other monitored area is accessed (e.g. the
boot hatch 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 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. Interior monitoring*
This is a monitoring or control function incor-
porated in the anti-theft alarm* which de-
tects 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 me-
chanically with the key and when the but-
ton  on the remote control is used.

twice. It only deactivates the interior moni-
tor. The alarm system remains activated.
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. WARNING
● The “deadlock” system remains deactiva-
ted if the interior monitor 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 inte-
rior monitor, this will be indicated by a flash-
ing of the warning lamp on the driver door when the vehicle is opened. This flashing will
be different to that for an activated alarm.
