The safety equipment mentioned above
works together to provide you and your pas-
sengers with the best possible protection in
the event of an accident. However, these
safety systems can only be effective if you
and your passengers are sitting in a correct
position and use this equipment properly.

– Adjust the steering wheel so that there is a
distance of at least 25 cm between the
steering wheel and the centre of your chest
››› Fig. 55 .
– Mo v
e the driver seat forwards or backwards
so that you are able to press the accelera-
tor, brake and clutch pedals to the floor
with your knees still slightly angled ››› .
– Ensure that you can reach the highest point
of the steering wheel.
– Adjust the head restraint so that its upper
edge is at the same level as the top of your
head, or as close as possible to the same
level as the top of your head ››› Fig. 56 .
– Mo v

e the seat backrest to an upright posi-
tion so that your back rests completely
against it.
– Fasten your seat belt securely ››› page 43.
– Keep both feet in the footwell so that you
have the vehicle under control at all times.

can lead to severe injuries.
● Adjust the driver seat so that there is at
least 25 cm distance between the centre of 38

the chest and the centre of the steering
wheel
››› Fig. 55. If you are sitting closer than
25 c m, the airb
ag system cannot protect you
properly.
● If your physical constitution prevents you
from maintaining the minimum distance of 25
cm, contact a specialised workshop. The
workshop will help you decide if special spe-
cific modifications are necessary.
● When driving, always hold the steering
wheel with both hands on the outside of the
ring at the 9 o'clock and 3 o'clock positions.
This reduces the risk of injury when the driver
airbag is triggered.
● 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). In such
cases, if the airbag is triggered, you may sus-
tain injuries to the arms, hands and head.
● To reduce the risk of injury to the driver
during sudden braking manoeuvres or an ac-
cident, never drive with the backrest tilted far
back! The airbag system and seat belts can
only provide optimal protection when the
backrest is in an upright position and the
driver is wearing his or her seat belt correct-
ly.
● Adjust the head restraint properly to ach-
ieve optimal protection. Adjusting the steering wheel position

could cause an accident.
● Move the lever up firmly so the steering
wheel position does not accidentally change
during driving. risk of accident!
● Make sure you are capable of reaching and
firmly holding the upper part of the steering
wheel: risk of accident!
● If you adjust the steering wheel so that it
points towards your face, the driver airbag
will not protect you properly in the event of
an accident. Make sure that the steering
wheel points towards your chest. Correct sitting position for front
passenger
For your own safety and to reduce the risk of
injury in the event of an accident, we recom-
mend the following adjustments for the front
passenger:
– Move the front passenger seat back as far
as possible ››› .–
Move the seat backrest to an upright posi-
tion so that your back rests completely
against it.
– Adjust the head restraint so that its upper
edge is at the same level as the top of your
head, or as close as possible to the same
level as the top of your head ››› page 41.
– Always keep both feet in the footwell in
front of the front passenger seat.

● 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 between 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 minimum distance of 25

dash panel, out the window or on the seat. An
incorrect sitting position exposes you to an
increased risk of injury in case of a sudden
braking or an accident. If the airbag is trig-
gered, you could sustain severe injuries due
to an incorrect sitting position.
●
To reduce the risk of injury to the front pas-
senger in events such as sudden braking ma-
noeuvres or an accident, never travel with the
backrest tilted far back! The airbag system
and seat belts can only provide optimal pro-
tection when the backrest is in an upright po-
sition 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 incorrect positioning
of the belt web or to the incorrect sitting po-
sition!
● Adjust the head restraint correctly in order
to achieve maximum protection. Correct sitting position for passengers
in the rear seats
To reduce the risk of injury in the event of a
sudden braking manoeuvre or an accident,
passengers on the rear seat bench must con-
sider the following:
–
Sit up straight.
– Adjust the head restraint to the correct po-
sition ››› page 41 . –
Alw ays keep both feet in the footwell in
front of the rear seat.
– Fasten your seat belt securely ››› page 43.
– Use an appropriate child restraint system
when you take children in the vehicle
››› page 56. WARNING
● If the passengers in the rear seats are not
sitting properly, they could sustain severe in-
juries.
● Adjust the head restraint correctly in order
to achieve maximum protection.
● Seat belts can only provide optimal protec-
tion when seat backrests are in an upright
position and the vehicle occupants are wear-
ing their seat belts correctly. If passengers In
the rear seats are not sitting in an upright po-
sition, the risk of injury due to incorrect posi-
tioning of the seat belt increases. Examples of incorrect sitting
positions
Seat belts can provide optimal protection on-
ly when the belt webs are properly posi-
tioned. Incorrect sitting positions substan-
tially reduce the protective function of seat
belts and increase the risk of injury due to in-
correct seat belt position. As the driver, you
are responsible for all passengers, especially
children.–
Never allow anyone to assume an incorrect
sitting position in the vehicle while travel-
ling ››› .
The following list contains examples of sit-
ting positions that could be dangerous for all
vehicle occupants. The list is not complete,
but we would like to make you aware of this
issue.
Therefore, whenever the vehicle is in motion:
● Never stand in the vehicle.
● Never stand on the seats.
● 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 foot-
well.
● Never travel without wearing the seat belt.
● Do not allow anyone to travel in the lug-
gage compartment.
