What affects driving safety?
Driving safety is largely determined by your driving style
and the personal behaviour of all vehicle occupants.
As a driver, you are responsible for yourself and your passengers.
When your concentration or driving safety is affected by any cir-
cumstance, you endanger yourself as well as others on the road
⇒ 
, for this reason:
– Always pay attention to traffic and do not get distracted by pas-
sengers or telephone calls.
– Never drive when your driving ability is impaired (e.g. by medi-
cation, alcohol, drugs).
– Observe traffic laws and speed limits. 

10Safe driving
Sitting position for vehicle occupants
Introduction
WARNING
● The front seats, head restraints and seat belts must always be adjus-
ted to the size of the vehicle occupant to provide you and your passen-
gers with the greatest possible protection.
● Ensure your correct sitting position before setting off, and do not
change this during the journey. Also advise your passengers to ensure
their correct sitting positions not to be changed.
● A vehicle occupant sitting in an incorrect position is at risk of serious
injury in the event that an airbag is activated.
● If the passengers in the rear seats are not sitting in an upright posi-
tion, they are more likely to be injured due to the incorrect position of the
seat belts.
● It is important that the driver keeps at a minimum of 25 cm from the
steering wheel. It is important that the passenger keeps at a minimum of
25 cm from the dash panel. The airbag system will not be able to give the
required protection if the minimum distance is not observed. This can
cause a risk of fatal injury!
● When driving, always hold the steering wheel with both hands on the
outside part at the 9 o'clock and 3 o'clock positions. Never hold the
steering wheel at the 12 o'clock position, or in any other manner (e.g. in
the centre of the steering wheel or along its interior edge). In such cases,
if the airbag is triggered, you may sustain injuries to the arms, hands
and head.
● The backrests must not be reclined too far back while driving. This
could limit the effect of the seat belts and the airbag system. Risk of in-
jury!
WARNING (Continued)
● Objects must not be placed in the footwell, as they could move to the
area of the pedals in the event of a braking manoeuvre or change of direc-
tion. This would prevent the clutch, brake or accelerator from being
pressed.
● Always keep your feet on the footwell when the vehicle is moving;
never rest them on the dash panel, on the window or on the seat! An in-
correct sitting position exposes you to an increased risk of injury in case
of a sudden braking or an accident. If the airbag is triggered, you could
sustain severe injuries due to an incorrect sitting position!

Safe driving
WARNING
● An incorrect sitting position of the front passenger can lead to severe
injuries.
● Adjust the front passenger seat so that there is at least 25 cm be-
tween your chest and the dash panel. If you are sitting closer than 25 cm,
the airbag system cannot protect you properly.
● If your physical constitution prevents you from maintaining the mini-
mum distance of 25 cm, contact a specialised workshop. The workshop
will help you decide if special specific modifications are necessary.
● Always keep your feet in the footwell when the vehicle is moving;
never rest them on the dash panel, out the window or on the seat. An in-
correct sitting position exposes you to an increased risk of injury in case
of a sudden braking or an accident. If the airbag is triggered, you could
sustain severe injuries due to an incorrect sitting position.
● To reduce the risk of injury to the front passenger in events such as
sudden braking manoeuvres or an accident, never travel with the back-
rest tilted far back! The airbag system and seat belts can only provide op-
timal protection when the backrest is in an upright position and the front
passenger is wearing his or her seat belt properly. The further the seat
backrests are tilted to the rear, the greater the risk of injury due to incor-
rect positioning of the belt web or to the incorrect sitting position!
● Adjust the head restraint correctly in order to achieve maximum pro-
tection.
 Correct sitting position for passengers in the rear seats
Passengers in the rear seats must sit up straight, keep their
feet in the footwells, have the head restraints positioned for
use and wear their seat belts properly.
To reduce the risk of injury in the event of a sudden braking ma-
noeuvre or an accident, passengers on the rear seat bench must
consider the following:
–
Adjust the head restraint to the correct position. ⇒ page 15
– Always keep both feet in the footwell in front of the rear seat.
– Fasten your seat belt securely ⇒ page 19.
– Use an appropriate child restraint system when you take chil-
dren in the vehicle ⇒ page 47.
WARNING
● If the passengers in the rear seats are not sitting properly, they could
sustain severe injuries.
● Adjust the head restraint correctly in order to achieve maximum pro-
tection.
● Seat belts can only provide optimal protection when seat backrests
are in an upright position and the vehicle occupants are wearing their
seat belts correctly. If passengers In the rear seats are not sitting in an
upright position, the risk of injury due to incorrect positioning of the seat
belt increases.

16Safe driving
● Never kneel on the seats.
● Never tilt your seat backrest far to the rear.
● Never lean against the dash panel.
● Never lie on the rear bench.
● Never sit on the front edge of a seat.
● Never sit sideways.
● Never lean out of a window.
● Never put your feet out of a window.
● Never put your feet on the dash panel.
● Never put your feet on the surface of a seat.
● Do not allow anyone to travel in the footwell.
● Never travel without wearing the seat belt.
● Do not allow anyone to travel in the luggage compartment.
WARNING
● Any incorrect sitting position increases the risk of severe injuries.
● Sitting in an incorrect position exposes the vehicle occupants to se-
vere injuries if airbags are triggered, by striking a vehicle occupant who
has assumed an incorrect sitting position.
● Before the vehicle moves, assume the proper sitting position and
maintain it throughout the trip. Before every trip, instruct your passen-
gers to sit properly and to stay in this position during the trip ⇒ page 10,
Sitting position for vehicle occupants.
 Pedal area
Pedals
The operation of all pedals must never be impaired by ob-
jects or floor mats.
– Ensure that you can always press the accelerator, brake and
clutch pedals unimpaired to the floor.
– Ensure that the pedals can return unimpaired to their initial po-
sitions.
Use only floor mats which leave the pedal area free and can be securely fas-
tened on the footwell.
If a brake circuit fails, the brake pedal must be pressed down thoroughly in
order to stop the vehicle.
Wearing suitable shoes
Always wear shoes which support your feet properly and give you a good
feeling for the pedals.
WARNING
● Restricting pedal operation can lead to critical situations while driv-
ing.
● Never place objects on the driver footwell. An object could move into
the pedal area and impair pedal operation. In the event of a sudden driv-
ing or braking manoeuvre, you will not be able to operate the brake,
clutch or accelerator pedal. Risk of accident!

18Safe driving
WARNING (Continued)
● Never allow children to play in or around the vehicle. Close and lock
all the doors and rear lid when you leave the vehicle. Before you lock the
vehicle, make sure that there are no adults or children in the vehicle.
● Never transport passengers in the luggage compartment. All vehicle
occupants must have their seat belt fastened ⇒ page 19.
Note
● Air circulation in the vehicle helps reduce fogging of the windows. Used
air escapes through ventilation slits in the side trim of the luggage compart-
ment. Ensure that the ventilation slits are never covered.
● Straps for securing the load to the fastening rings are commercially
available. 
Fastening rings*
There can be four fastening rings in the luggage compart-
ment for fastening luggage and other objects.
– Always use suitable and undamaged straps to secure luggage
and other objects to the fastening rings ⇒ 
in Loading the lug-
gage compartment on page 17.
Bear in mind that in the case of a collision or accident, even small and light
objects that are not firmly fixed can be projected at the occupants causing
injury.
Example: An object weighing 4.5 kg is lying unsecured in the vehicle. Dur-
ing a frontal collision at a speed of 50 km/h (30 mph), this object generates
a force corresponding to 20 times its weight. That means that the effective
weight of the object increases to about 90 kg. You can imagine the severity
of the injuries which might be sustained if this object strikes an occupant as it flies through the interior of the vehicle. This increased risk of injury will be
further increased if a loose object is struck by an inflating airbag.
WARNING
● If pieces of luggage or other objects are secured to the fastening
rings with inappropriate or damaged retaining cords, injuries could be
sustained in the event of braking manoeuvres or accidents.
● To prevent pieces of luggage or other objects from flying forward, al-
ways use appropriate retaining cords which are secured to the fastening
rings.
● Never secure a child seat on the fastening rings.

Airbag system
In certain types of accident the front, side and curtain airbags may be trig-
gered together.
When the system is triggered, the airbag is filled with propellant gas. In the
process, the curtain airbag covers the side windows and door pillars.
The airbags deploy extremely rapidly, within thousandths of a second, to
provide additional protection in the event of an accident. A fine dust may
develop when the airbag deploys. This is normal and it is not an indication
of fire in the vehicle.
The fully deployed airbags cushion the movement of the front occupants
and help to reduce the risk of injury to the upper body.
The special design of the airbag allows the controlled escape of the propel-
lant gas when an occupant puts pressure on the bag. Thus, the head and
chest are surrounded and protected by the airbag. 
Safety notes on the operation of the curtain airbag system
If you use airbags correctly, they can considerably reduce
the risk of injury in many kinds of accident.
WARNING
● 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.
● For safety reasons, the curtain airbag must be disabled in those vehi-
cles fitted with a screen dividing the interior of the vehicle. See a Techni-
cal Service to make this adjustment.
WARNING (Continued)
● There must be no other persons, animals or objects between the oc-
cupants of the outer seats and the deployment space of the curtain air-
bags so that the curtain airbag can deploy without restriction and pro-
vide 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.
● 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.
