– Press the upper part of the shoulder belt guide and hold it in this position ⇒page 27, fig. 17 .
– Move the shoulder belt guide up or down until you have adjusted the seat belt ⇒page 25.
– After adjusting, pull the shoulder belt sharply to check that the catch on the shoulder belt guide is engaged securely.Incorrectly fastened seat belts
Incorrectly worn seat belts can cause severe injuries.Seat belts can provide optimal protection only if the belt web is
properly worn. The seat belts must be fastened exactly in the order
described in this chapter. An incorrect sitting position impairs
substantially the protection a seat belt offers and can lead to severe
or fatal injuries. The risk of severe or fatal injuries is especially
increased when a deploying airbag strikes an occupant who has
assumed an incorrect sitting positi on. As driver, you are responsible
for all vehicle occupants, especially children. Therefore:
– Never permit anyone to assume an incorrect sitting position in the vehicle while travelling ⇒.
WARNING
•An incorrectly worn seat belt increases the risk of severe injuries.•Before every trip, instruct your passengers to adjust their seat belts
properly and to wear them during the trip.•Read and always observe information and warnings concerning the use
of seat belts ⇒page 23.
Belt tension devicesFunction of the belt tension device
During a frontal collision, the seat belts on the front seats are
retracted automatically.The seat belts for the front occupants are equipped with belt tension devices.
Sensors will trigger the belt tension devices during severe head-on, lateral
and rear collisions only if the seat belt is being worn. This retracts and
tightens the seat belts, reducing the forward motion of the occupants.
The belt tension device can be triggered only once.
The belt tension devices will not be triggered in the event of a light frontal,
side or rear collision, if the vehicle overturns, or in situations where no large
forces act on the front, side or rear of the vehicle.
Note
•If the belt tension devices are triggered, a fine dust is produced. This is
normal and it is not an indication of fire in the vehicle.•The relevant safety requirements must be observed when the vehicle or
components of the system are scrapped. A qualified workshop is familiar with
these regulations and will be pleased to pass on the information to you.Service and disposal of belt tension devicesThe belt tension devices are components of the seat belts that are installed
in the seats of your vehicle. If you work on the belt tension devices or remove
and install parts of the system when performing other repair work, the seat
belt may be damaged. The consequence may be that, in the event of an acci-
dent, the belt tension devices function incorrectly or not at all.

Airbag system
38hold the passengers in the front seats and the outer rear seats in a position
where the side airbags can provide maximum protection.
The airbag system is not a substitute for seat belts, but it is an integral part
of the vehicle's overall passive safety system. Please bear in mind that the
airbag system can only work effectively when the occupants are wearing their
seat belts. Therefore, it is most important to wear the seat belts at all times,
not only because this is required by law in most countries, but also for your
safety ⇒ page 19, “Brief Introduction”.
The side airbag system will not be triggered if:•the ignition is switched off,•there is a minor side collision,•there is a frontal collision,•there is a rear-end collision,•the vehicle turns over.
The main parts of the airbag system are:•an electronic control and monitoring system (control unit),•The front side airbags in the backrests of the front seats and the rear side
airbags in the lining of the rear wheel housing.•a warning lamp
 in the dash panel insert ⇒page 31.
The airbag system operation is monitored electronically. The airbag warning
lamp will light up for approx. 4 seconds every time the ignition is switched on
(self-diagnosis).
WARNING
•In a side-on 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, unless the holes left by the loudspeakers have been
correctly closed.•Always check that the openings are closed or covered if loudspeakers
or other equipment are fitted in the interior door panels.•Any work carried out to the doors should be made in a qualified author-
ised workshop.•The seat belts and airbags can only provide maximum protection if the
occupants are seated correctly ⇒page 10, “Proper sitting position for
occupants”.•If a fault has occurred in the airbag system, have the system checked
immediately by a qualified workshop. Otherwise, during a side collision,
the system may fail to trigger, or not trigger correctly.WARNING (continued)

Airbag system
40Safety notes on the operation of the side airbag system
If airbags are used correctly, they can considerably reduce the
risk of injury in side impact collisions.
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 allow children or
other passengers to travel in this position. It is also important not to attach
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 bolster because the system may be damaged. In this case, the
side airbags would not be triggered.•Under no circumstances should protective covers be fitted over the
driver seat or front passenger seat unless the covers have been expressly
approved for use in your vehicle. Because the airbag is triggered from the
side of the backrest, the use of non-approved seat covers would obstruct
the side airbag, seriously reducing the airbag's effectiveness ⇒ page 218,
“Accessories, replacement of parts and modifications”.•Any damage to the original seat upholstery or around the seams of the
side airbag units must be repaired immediately by a qualified workshop.•The airbags provide protection for just one accident; replace them once
they have deployed.
•When children assume an incorrect sitting position, they expose them-
selves to an increased risk of injury in the event of an accident. This is
particularly the case if the child is travelling on the front passenger seat
and the airbag system is triggered in an accident; this could have critical
consequences including serious injury or death ⇒ page 46, “Child safety”.•Any work on the side airbag system or removal and installation of the
airbag components for other repairs (such as removal of the front seat)
should only be performed by a qualified 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 functioning of the side and
head 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 made in a qualified workshop.WARNING (continued)

•There must be no other persons, animals or objects between the occu-
pants of the outer seats and the deployment space of the curtain airbags
so that the curtain airbag can deploy without restriction 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
windows ⇒page 218, “Accessories, replacement of parts and modifica-
tions”.•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 hangers.•The airbags provide protection for just one accident; replace them once

Unlocking and locking
104Anti-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 car 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 car 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•Undue manipulation of the alarm•Battery handling
The acoustic signals sound and the indicators 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
car. 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, access is gained to a second secured zone
(e.g. the tailgate is opened after a door has been opened), the warning signal
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.

Lights and visibility
114•If you are towing a trailer equipped with a rear fog light on a vehicle with
a factory-fitted towing bracket , the rear fog light on the car will automatically
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 rear
lights and the indicators may be temporarily misted. This has no influence on
the life expectancy 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 headlights are automat-
ically switched on by a light-sensitive sensor if you drive into a tunnel, for
example.
The motorway function switches on the dipped headlights when the vehicle
is driven at over 140 km/h for a few seconds and it switches the lights off
when the vehicle is driven at less than 65 km/h for a few minutes.
The rain sensor switches on the dipped headlights when the windscreen
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 127.
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
•If automatic headlight control is switched on, the headlights will not be
switched on in fog or heavy rain. 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
 or  if the vehicle is not fitted with the coming
home function.
