– Take hold of the top guide fitting and slide it up or down so that the shoulder part of the seat belt is positioned roughly midway
over the shoulder, although it must never rest against the neck
⇒ page 25, fig. 16 ⇒ in “Seat belt position” on page 23.
– After adjusting, pull the belt sharply to check that the catch on the guide fitting is engaged securely.
NoteIt is also possible to adjust the height of the front seats to obtain the best
position for the front seat belts.Incorrectly fastened seat belts
Incorrectly worn seat belts can cause severe or even mortal
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 in correct 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 position. As the driver, you are respon-
sible for all vehicle occupants, especially children. Therefore:
– Never allow anyone to wear the seat belt incorrectly while the vehicle is moving ⇒.
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 for the whole journey.•Read and always observe information and warnings concerning the use
of seat belts ⇒page 21.
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.

Side airbags*Description of side airbags
The airbag system is not a substitute for the seat belts.The front side airbags are located in the driver's seat and front passenger's
seat backrests ⇒fig. 23. The rear side airbags are located in the rear wheel
housing lining. The locations are identified by the text “AIRBAG” in the upper
region of the backrests and in the rear wheel housing lining.
Together with the seat belts, the side airbag system gives the front seat occu-
pants additional protection for the upper body in the event of a severe side
collision ⇒page 40, “Safety notes on the operation of the side airbag
system”.
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 impact. 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 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 18, “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 29.
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.

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 us ed 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 exer ted 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 un less 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 214,
“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 qualif ied 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)

Tyre pressure monitoring*Introduction
The tyre pressure monitoring system constantly checks the
pressure of the tyres.The system warns the driver in the event of a loss of pressure by means of
symbols and messages in the instrument panel display. The system works
with the help of the ABS sensors in the wheels.
Please bear in mind that the tyre inflation pressure is also influenced by the
temperature of the tyre. Tyre pressure increases about 0.1 bar for each 10°C
in tyre temperature increase. The tyre heats up while the vehicle is being
driven and the tyre pressure will rise accordingly. Therefore, you should only
adjust the tyre pressures when they are
cold (i.e. approximately at ambient
temperature).
To ensure that the tyre pressure monitoring system works reliably, you should
check and, if necessary, adjust the tyre pressures at regular intervals and
store the correct pressures (reference values) in the system.
A tyre pr essure i nfor ma ti on lab e l is a tta che d to t he insi de o f the fu el ta nk f lap.
WARNING
•Never adjust tyre pressure when the tyres are hot. This may damage or
even burst the tyres. Risk of accident!•An insufficiently inflated tyre flexes a lot more at high speeds and
causes significant heating of the tyre. Under these conditions, the tyre
bead may be released or the tyre may burst. Risk of accident!For the sake of the environment
Under-inflated tyres lead to increased fuel consumption and tyre wear.
Note
•Responsibility for ensuring that the tyres are correctly inflated remains
with the driver; the system can only provide assistance.•Pressure can only be adjusted when the tyres are at ambient
temperature.

If you set the light switch to “AUTO”, the headlights will switch
on and switch off automatically according to the ambient light
level.Turning on dipped-beam headlights
–Turn the light switch ⇒ fig. 85 to the AUTO position.
Turning off dipped-beam headlights
– Turn the light switch to position O.The symbol on the switch lights up when the switch is in the AUTO position.
The dipped beams, side lights, rear lights and number plate lights come on
together when the headlights are switched on automatically.
When you are using the automatic headlights switch, you can also operate
the main beam headlights, however, please note the following: If you enable the main beam headlights while using the automatic headlights function
during the day
(e.g. when driving through a tunnel), but do not disable them
again, only the dipped beam headlights will come on the next time the lights
are automatically switched on. To be able to use the main beam headlights
again, you must first pull the main beam lever back to the "off" position and
then push it forward again to "on".
The side lights, headlights, fog lights and rear fog light can still be switched
on manually in the normal way by using lights switch ⇒page 115.
The mirror inside the vehicle is fitted with sensors that measure the ambient
light. The dipped-beam headlights will be switched on automatically if the
available light drops below the factory preset value (for instance when driving
through a tunnel, etc.). The headlights switch off again automatically when
the light level increases ⇒.
WARNING
•The automatic dipped-beam headlights are only intended to assist the
driver. Automatic dipped-beam headlights do not relieve the driver of his
or her responsibility to control them and turn off or turn on the lights manu-
ally according to weather or lighting conditions. The light sensors are, for
example, unable to detect rain and fog - you should therefore always switch
on the dipped-beam headlights
 manually in these conditions and when
driving after dark.
•Observe all relevant legal requirements when using the signalling and
lighting systems described here.Note
•If automatic headlight switching is activated, when the ignition is turned
off the dipped-beam headlights are turned off, and when the key is removed
from the ignition the side lights are turned off.•If you have to attach any type of sticker on the windscreen, do not do so
in front of the sensors. Doing so could prevent the automatic dipped-beam
