Seat belts
Seat belt tensioners
Function of the seat belt tensioner
During a frontal collision, the seat belts on the front seats
are retracted automatically. The seat belts for the occupants in the front seats are equipped with belt
tensioners. Sensors will trigger the belt tensioners 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 seat belt tensioner can be triggered only once.
The seat belt tensioners 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 seat belt tensioners 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. Specialised workshops are famili-
ar with these regulations, which are also available to you. 
Service and disposal of belt tensioners
The belt tensioners are components of the seat belts that are installed in
the seats of your vehicle. If you work on the belt tensioners 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 tensioners function incorrectly or not at all. So that the effectiveness of the seat belt tensioner is not reduced and that
removed parts do not cause any injuries or environmental pollution, regula-
tions, which are known to the specialised workshops, must be observed.
WARNING
● Improper use or repairs not carried out by qualified mechanics in-
crease the risk of severe or fatal injuries. The belt tensioners may fail to
trigger or may trigger in the wrong circumstances.
● Never attempt to repair, adjust, remove or install parts of the belt ten-
sioners or seat belts.
● The seat belt tensioner, seat belt and automatic retractor cannot be
repaired.
● Any work on the belt tensioners and seat belts, including the removal
and refitting of system parts in conjunction with other repair work, must
be performed by a specialised workshop only.
● The belt tensioners will only provide protection for one accident and
must be changed if they have been activated.

38Airbag system
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 control lamp  on the dash panel ⇒ page 32
The airbag system operation is monitored electronically. The airbag control
lamp will light up for approx. 4 seconds every time the ignition is switched
on (self-diagnosis).
WARNING
● 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.
WARNING (Continued)
● Never drive the vehicle if the loudspeakers in the door panels have
been removed, unless the holes left by the loudspeakers have been cor-
rectly 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 an authorised
specialised 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 specialised workshop. Otherwise, during a side colli-
sion, the system may fail to trigger, or not trigger correctly.

WARNING (Continued)
use of non-approved seat covers would obstruct the side airbag, serious-
ly reducing the airbag's effectiveness ⇒ page 226, Accessories, replace-
ment 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 specialised
workshop.
● The airbags provide protection for just one accident; replace them
once they have deployed.
● When children assume an incorrect sitting position, they expose
themselves 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 specialised workshop. Otherwise, faults
may occur during the airbag system operation.WARNING (Continued)
● 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 head airbags neither the doors nor the door panels should be modi-
fied 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 specialised workshop.

● 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 they have deployed.
● Any work on the curtain airbag system or removal and installation of
the airbag components for other repairs (such as removal of the roof lin-
ing) 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 head airbags neither the doors nor the door panels should be modi-
fied 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 specialised workshop.

ing, the brake fluid level ⇒ page 249, Brake fluid in the reservoir is too
low. Risk of accident. Stop the vehicle and do not drive on. Obtain techni-
cal assistance.
● If the brake warning lamp  lights up together with the ABS warning
lamp , the control function of the ABS could be out of action. This could
cause the rear wheels to lock quickly when you brake. This could cause
the rear to break away. Risk of skidding. Stop the vehicle and seek tech-
nical assistance.

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.
Activation
– It is automatically turned on with the anti-theft alarm, when the
vehicle is locked mechanically with the key and when the but-
ton 
on the remote control is used.
Deactivation
– Press the button 
on the remote control twice. Only the volu-
metric sensor is deactivated. The alarm system remains activa-
ted.
WARNING
● The deadlock system remains deactivated if the volumetric sensor 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 volumetric sensor, this will be in-
dicated by a flashing of the warning lamp on the driver door when the vehi-
cle is opened. This flashing will be different to that for an activated alarm. 

116Lights and visibility
● 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 vehicle will automat-
ically 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 useful life of the lighting system. The lights will soon demist when
they are switched on. 

ing
Activation
– Rotate the switch to the  position. This indication will light
up.
Deactivation
– Turn the light switch to . 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 interval wipe is switched off
for some minutes
⇒ page 129.
When the automatic dipped beam light control is connected but the dipped
beam lights are off, the warning lamp  lights up on the light control
⇒ Fig. 71. If the automatic control switches on the dipped lights, the instru-
ment and control lighting is also switched on.
WARNING
● Even if the automatic headlight control is switched on, the dipped
beam 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 audible warning will only sound if the light
control is in the position  or  if the vehicle is not fitted with the coming
home function.
● If the daylight driving automatic light function is switched on, the fog
lights or rear fog light cannot be switched on in addition.
● The use of the lighting described here is subject to the relevant statutory
requirements.
● Do not put stickers on the windscreen in front of the sensor. This may
cause disruptions or faults in the automatic lighting system.
● To avoid damage to the tail lights, the lights mounted on the rear lid go
off when the rear lid is opened (depending on the country). 
