What

affects driving safety? As a driver, you are responsible for yourself
and your passengers. When your concentra-
tion 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 passengers or telephone calls.
– Never drive when your driving ability is im-
paired (e.g. by medication, alcohol, drugs).
– Observe traffic laws and speed limits.
– Always reduce your speed as appropriate
for road, traffic and weather conditions.
– When travelling long distances, take
breaks regularly - at least every two hours.
– If possible, avoid driving when you are tired
or stressed. WARNING
When driving safety is impaired during a trip,
the risk of injury and accidents increases. Safety equipment
Never put your safety or the safety of your
passengers in danger. In the event of an acci-
dent, the safety equipment may reduce the
risk of injury. The following list includes most
of the safety equipment in your SEAT:
● Three-point seat belts

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.

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.

Safety
Rear head restraints – The rear head restraints have 2 positions:
use and
non-use.
– One position for use (head restraint raised)
››

› Fig. 58. In this position, the head re-
str
aints are used normally, protecting pas-
sengers along with the rear seat belts.
– And one position for non-use (head re-
s

traint lowered).
– To fit the head restraints in position for use,
pull on the edges with both hands in the
direction of the arrow. WARNING
● Under no circumstances should the rear
passengers travel while the head restraints
are in the non-use position. See the warning
label located on the rear side fixed window
››› Fig. 59.
● Do not sw

ap the centre rear head restraint
with either of the outer seat rear head re-
straints. Risk of injury in case of an accident! CAUTION
Note the instructions on the adjustment of
the head restraints ››› page 107. Pedal area
Pedals –
Ensure that you can always press the accel-
erator, brake and clutch pedals unimpaired
to the floor.
– Ensure that the pedals can return unim-
paired to their initial positions.
– Ensure that the floor mats are securely fas-
tened during the trip and do not obstruct
the pedals ››› .
Only use floor mats which leave the pedal
area free and can be secured to prevent them
from slipping. You can obtain suitable floor
mats from a specialised dealership. Fasten-
ers* for floor mats are fitted in the footwells.
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 crit-
ical situations while driving. ●
Never lay or fit floor mats or other floor cov-
erings over the original floor mats. This
would reduce the pedal area and could ob-
struct the pedals. Risk of accident.
● Never place objects in the driver footwell.
An object could move into the pedal area and
impair pedal operation. In the event of a sud-
den driving or braking manoeuvre, you will
not be able to operate the brake, clutch or ac-
celerator pedal. Risk of accident! 42

sten your seat belt
The seat belt cannot offer its full protection if
the seat belt is not positioned correctly.
● Adjust the seat and head restraint correctly.
● To fasten the belt, take hold of the latch
plate and pull it slowly across your chest and
lap.
● Insert the latch plate into the buckle for the
appropriate seat and push it down until it is
securely locked with an audible click

Seat belts
The seat belts are equipped with an automat-
ic retractor on the shoulder strap. Full free-
dom of movement is permitted when the
shoulder belt is pulled slowly. However, dur-
ing sudden braking, during travel in steep
areas or bends and during acceleration, the
automatic retractor on the shoulder belt is
locked.
The automatic belt retractors on the front
seats are fitted with seat belt tensioners
››› page 47 .
R el
easing the seat belt
● Press the red button on the belt buckle
››› Fig. 64 B
. The latch plate is released and
springs out ››› .
● Guide the belt back by hand so that it rolls
up easily and the trim is not damaged.
Adjusting the seat belt
Seat belts offer their maximum protection on-
ly when they are properly positioned
››› Fig. 65 . WARNING
● The seat belts offer best protection only
when the backrests are in an upright position
and the seat belts have been fastened prop-
erly.
● Never put the latch plate in the buckle of
another seat. If you do this, the seat belt will not protect you properly and the risk of injury
is increased.
●
Never unbuckle a seat belt while the vehi-
cle is in motion. If you do, you increase the
risk of sustaining severe or fatal injuries.
● An incorrectly worn seat belt can cause se-
vere injuries in the event of an accident.
● For pregnant women, the lap part of the
seat belt must lie as low as possible over the
pelvis, never across the stomach, and always
lie flat so that no pressure is exerted on the
abdomen ››› Fig. 65.
● Alw

ays engage the retractor lock when you
are securing a child seat in group 0, 0+ or 1
››› page 56.
● Re

ad and observe the warnings ››› page 44. Seat belt tensioners
How the seat belt tensioner works 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. Sen-
sors will trigger the belt tensioners only dur-
ing severe head-on, lateral and rear-end colli-
sions and only if the seat belt is 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 col-
lision, 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 work-
shops are familiar 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 tension-
ers 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 accident, the belt
tensioners function incorrectly or may not
function at all.
So that the effectiveness of the seat belt ten-
sioner is not reduced and that removed parts

Transporting children safety
Follow the manufacturer's instructions and
observe any statutory requirements when in-
stalling and using child seats. Always read
and note ››› page 57 .
W e r
ecommend you always carry the manu-
facturer's Child Seat Instruction Manual to-
gether with the on-board documentation.
Important information regarding the
front passenger's airbag Fig. 76
Passenger's side sun visor: airbag
sticker. Fig. 77
On the rear frame of the passenger
side door: airbag sticker. A sticker with important information about
the passenger airbag is located on the pas-
senger's sun visor and/or on the passenger
side door frame. Read and always observe
the safety information included in the follow-
ing chapters:
● Safety distance with respect to the passen-
ger airbag ››› page 48 .
● Ob

jects between the passenger and the
passenger side airbag ››› in Front airbags
on page 51 .
The p a

ssenger side front airbag, when ena-
bled, is a serious risk for a child that is facing
backward since the airbag can strike the seat
with such force that it can cause serious or
fatal injuries. Children up to 12 years old
should always travel on the rear seat.
Therefore we strongly recommend you to
transport children on the rear seats. This is the safest location in the vehicle. Alternative-
ly, the front passenger airbag can be disa-
bled with a key-operated switch
››› page 55.
When transporting children, use a child seat
suitable for the age and size of each child
››› page 58. WARNING
● If a child seat is secured to the front pas-
senger seat, the risk to the child of sustain-
ing critical or fatal injuries in the event of an
accident increases.
● An inflating front passenger airbag can
strike the rear-facing child seat and project it
with great force against the door, the roof or
the backrest.
● Never install a child seat facing backwards
on the front passenger seat unless the front
passenger front airbag has been disabled.
Risk of potentially fatal injuries to the child!
However, if it is necessary, in exceptional ca-
ses, to transport a child in the front passen-
ger seat, the front passenger front airbag
must always be disabled ››› page 54. If the
passenger seat has a height adjustment op-
tion, move it to the highest, most upright po-
sition. If you have a fixed seat, do not install
any child restraint system in this location.
● For those vehicles that do not include a key
lock switch to deactivate the airbag, the vehi-
cle must be taken to a technical service.
● All vehicle occupants, especially children,
must assume the proper sitting position and
be properly belted in while travelling. » 57
