Safe driving
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
pa
s

sengers 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
● belt tension limiters for the front and rear
side se ats,
● B

elt tensioners for the front seats
● Belt height adjustment for the front seats
● Front airbags
● Side airbags in the front seat backrests
● Side airbags in the rear seat backrests*
● Head-protection airbags
● Active front head restraints*
● “ISOFIX” anchor points for child seats in
the rear s
ide seats with the “ISOFIX” system,
● Height-adjustable front head restraints
● Rear head restraints with in-use position
and non-use pos
ition
● Adjustable steering column 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.
Safety is everyone's business!

If your physical constitution prevents you
from maintaining the correct sitting position,
contact a specialised workshop for help with
any special devices. The seat belt and airbag
can only provide optimum protection if a cor-
rect sitting position is adopted. SEAT recom-
mends taking your car in for technical serv-
ice.
For your own safety and to reduce the risk of
injury in the event of an accident or sudden
braking or manoeuvre, SEAT recommend the
following positions:
Valid for the driver:
● Adjust the seat backrest to an upright posi-
tion so that
your back rests completely
against it. »

Danger of injuries due to an incorrect
s ittin
g po
sitionNumber of seats
The v
ehic

le has a total of 4 seats: 2 front
seats and 2 rear seats. Each seat is equipped
with a seat belt.
If the seat belts are worn incorrectly or not at
all, the risk of severe injuries increases. Seat
belts can provide optimal protection only if
the belt web is properly worn. Being seated
in an incorrect position means the seat belt
cannot offer its full protection. This could re-
sult in severe and even fatal injuries. The risk
of severe or fatal injuries is especially height-
ened when a deploying airbag strikes a vehi-
cle occupant who has assumed an incorrect
sitting position. The driver is responsible for
all passengers in the vehicle, particularly
children.
The following list shows just some examples
of incorrect sitting positions which can be
dangerous to all vehicle occupants.
When 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 too far to the
re ar

.
● Never lean against the dash panel. ●
Never lie on the re
ar seats.
● 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
or seat b
ackrest.
● Never travel in a footwell.
● Never travel on a seat without wearing the
seat belt
.
● Never carry any person in the luggage com-
partment
. WARNING
An incorrect sitting position in the vehicle
can l e

ad to severe injuries or death in the
event of sudden braking or manoeuvres, colli-
sion or accidents or if the airbag deploys.
● Before the vehicle moves, assume the prop-
er sitting po
sition and maintain it throughout
the trip. This also includes fastening the seat
belt.
● Never transport more people than there are
seats
with a seat belt available in the vehicle.
● Children must always be protected with an
appro
ved child restraint system suited to
their height and weight ››› page 63,
››› page 58.
● Always keep your feet in the footwell while
the vehic
le is in motion. Never, for example, put your feet on the surface of a seat or on
the da
sh p

anel and never put them out of a
window. Otherwise the airbag and seat belt
offer insufficient protection and the risk of in-
jury in the event of an accident is increased. WARNING
Before every trip, adjust the seat, the seat
belt and the he a

d restraints and instruct your
passengers to fasten their seat belts proper-
ly.
● Move the front passenger seat back as far
as po
ssible.
● Adjust the driver seat so that there is at
lea
st 25 cm distance between your chest and
the hub of the steering wheel. Adjust the
driver seat so that you are able to press the
accelerator, brake and clutch pedals to the
floor with your knees slightly angled and that
the distance between your knees and the
dash panel is at least 10 cm. If your physical
constitution prevents you from meeting these
requirements, contact a specialised work-
shop to make any modifications required.
● Never drive with the seat backrest tilted far
back.
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 position!
● Never drive with the seat backrest tilted
forw
ards. Should a front airbag deploy, it
could throw the seat backrest backwards and
injure the passengers of the rear seats. » 49

Seat belts
Pedal area P ed
a
ls Do not allow floor mats or other objects to
ob
s

truct the free passage of the pedals.
Floor mats should leave the pedal area free
and unobstructed and be correctly secured in
the footwell zone.
In the event of failure of a brake circuit, the
brake pedal must be pressed harder than
normal to brake the vehicle. WARNING
Objects falling into the driver's footwell could
prev ent

use of the pedals. This could lead the
driver to lose control of the vehicle, increas-
ing the risk of a serious accident.
● Make sure the pedals can be used at all
times, with no o
bjects rolling underneath
them.
● Always secure the mat in the footwell.
● Never place other mats or rugs on top of
the original
mat supplied by the factory.
● Ensure that no objects can fall into the driv-
er's footw
ell while the vehicle is in motion. CAUTION
The pedals must always have free and unob-
struct ed p

assage to the floor. For example, in
case of a fault in the brake circuit, the brake pedal will need to be pressed further to stop
the v
ehic

le. To press the brake pedal down
further will require more force than usual. Seat belts
Wh y
w
ear a seat belt?
Introduction Check the condition of all the seat belts at
re
gu

lar intervals. If you notice that the belt
webbing, fittings, retractor mechanism or
buckle of any of the belts is damaged, the
belt must be replaced immediately by a spe-
cialised workshop ››› . The specialised
w ork
shop mu

st use the appropriate spare
parts corresponding to the vehicle, the
equipment and the model year. SEAT recom-
mends taking your car in for technical serv-
ice. WARNING
Unbuckled or badly buckled seat belts in-
cr e

ase the risk of severe or even fatal inju-
ries. The seat belt cannot offer its full protec-
tion if it is not fastened and used correctly.
● Seat belts are the most effective way of re-
ducing the ri
sk of sustaining severe or fatal
injuries in the event of an accident. Seat belts
must be correctly fastened when the vehicle
is in motion to protect the driver and all vehi-
cle occupants.
● Before each trip, every occupant in the ve-
hicle oc
cupants must sit properly, correctly
fasten the seat belt belonging to his or her
seat and keep it fastened throughout the trip. » 51

Seat belts
On the instrument panel
display
A passenger in the rear seats has fastened their seat
belt, if the seat is occupied.* Several warning and indication lamps light
up for a f
ew sec

onds when the ignition is
switched on, signalling that the function is
being verified. They will switch off after a few
seconds.
An audible warning will be heard if the seat
belts are not fastened as the vehicle drives
off and reaches a speed of more then
25 km/h (15 mph) or if the seat belts are un-
fastened while the vehicle is in motion. The
seat belt warning lamp  will also flash.
The warning lamp  does not switch off until
the driver and front passenger fasten their
seat belts while the ignition is switched on.
Seat belt status display for rear seats
The seat belt status display on the instru-
ment panel informs the driver, when the igni-
tion is switched on, whether any passengers
in the rear seats have fastened their seat
belts. The symbol  indicates that the pas-
senger in this seat has fastened “his or her”
seat belt ›››
Fig. 68.
The seat belt status is displayed for around
30 seconds when a seat belt in the rear seats
is fastened or unfastened. You can switch off
this display by pressing the 0.0 / SET button.The seat belt status flashes for a maximum of
30 sec
ond
s

when a seat belt in the rear seats
is unfastened while the vehicle is in motion.
An audible warning will also be heard if the
vehicle is travelling at over 25 km/h
(15 mph).

Drivers with properly worn seat belts
w i
l

l not be thrown forward in the event of sud-
den braking Properly worn seat belts hold the occupants
in the pr
oper po
s

ition. They also help prevent
uncontrolled movements that may result in
serious injury and reduce the risk of being
thrown out of the vehicle in case of an acci-
dent.
Vehicle occupants wearing their seat belts
correctly benefit greatly from the ability of the
belts to absorb kinetic energy. In addition, the front part of your vehicle and other pas-
sive s

afety features (such as the airbag sys-
tem) are designed to absorb the kinetic ener-
gy released in a collision. Taken together, all
these features reduce the releasing kinetic
energy and consequently, the risk of injury.
This is why it is so important to fasten seat
belts before every trip, even when "just driv-
ing around the corner".
Ensure that your passengers wear their seat
belts as well. Accident statistics have shown
that wearing seat belts is an effective means
of substantially reducing the risk of injury
and improving the chances of survival when
involved in a serious accident. Furthermore,
properly worn seat belts improve the protec-
tion provided by airbags in the event of an
accident. For this reason, wearing a seat belt
is required by law in most countries.
Although your vehicle is equipped with air-
bags, the seat belts must be fastened and
worn. The front airbags, for example, are only
triggered in some cases of head-on collision.
The front airbags will not be triggered during
minor frontal or side collisions, rear-end colli-
sions, rollovers or accidents in which the air-
bag trigger threshold value in the control unit
is not exceeded.
Therefore, you should always wear your seat
belt and ensure that all vehicle occupants
have fastened their seat belts properly before
you drive off!

Even at low speeds the forces acting on the
body in a c

possible to brace oneself with one's hands.
In a frontal collision, unbelted passengers
are thrown forward and will make violent con-
tact with the steering wheel, dash panel,
windscreen or whatever else is in the way
››› Fig. 70.
It is also important for rear passengers to
wear seat belts properly, as they could other-
wise be thrown forward violently through the
vehicle interior in an accident. Passengers in
the rear seats who do not use seat belts en-

›› page 58 and consist of the follow-
ing important functions:
Automatic belt retainer
Every seat belt is equipped with an automatic
belt retainer on the shoulder belt. If the belt
is pulled slowly or during normal driving, the
system allows for total freedom of movement
on the shoulder belt. However, during sud-
den braking, during travel in mountains or
bends and during acceleration, the automat-
ic belt retainer on the seat belt is locked is
pulled quickly.
Belt tensioners
The seat belts for the occupants in the front
seats are equipped with belt tensioners.
Sensors trigger the belt tensioners during se-
vere head-on, lateral and rear collisions and
retract and tighten the seat belts. If the seat
belt is loose, it is retracted to reduce the for-
wards movement of occupants or movement in the direction of the collision. The belt ten-
sioner w
ork

s in combination with the airbag
system. The belt tensioner will not be trig-
gered in the event of the vehicle overturning
if the side airbags are not deployed.
If the belt tensioner is triggered, a fine dust is
produced. This is normal and it is not an indi-
cation of fire in the vehicle.
Belt tension limiter
The belt tension limiter reduces the force of
the seat belt on the body in the event of an
accident. Note
The relevant safety requirements must be ob-
serv ed when the

vehicle is dismantled or sys-
tem components are removed. These require-
ments are known to specialised workshops
››› page 57. Service and disposal of belt tension
dev
ice

s If you work on the belt tensioners or remove
and in
s
t

all other parts of the vehicle when
performing other repair work, the seat belt
may be damaged. The consequence may be
that, in the event of an accident, the belt ten-
sioners function incorrectly or not at all. So that the effectiveness of the belt tensioner
is not

reduced and that removed parts do not
cause any injuries or environmental pollu-
tion, regulations must be observed. These re-
quirements are known to specialised work-
shops. WARNING
● Improper u se or r

epairs not carried out by
qualified mechanics increase the risk of se-
vere or fatal injuries. The belt tensioners may
fail to trigger or may trigger in the wrong cir-
cumstances.
● Never attempt to repair, adjust, remove or
inst
all parts of the belt tensioners or seat
belts.
● The seat belt tensioner, seat belt and auto-
matic r
etractor cannot be repaired.
● Any work on the belt tensioners and seat
belts, includin
g 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 pro-
tection for one ac
cident and must be changed
if they have been activated. For the sake of the environment

Airbag system
●
Bef or
e each trip, every occupant must sit
properly, correctly fasten the seat belt be-
longing to his or her seat and keeping it fas-
tened throughout the trip. This rule is valid
for all vehicle occupants. WARNING
Occupants sitting in the front of the vehicle
mu st

never carry any objects in the deploy-
ment space between them and the airbags,
as this increases the risk of sustaining inju-
ries if the airbag is triggered. This modifies
the airbag deployment space or the objects
may fly uncontrollably and hit your body.
● Never carry objects in your hand or on your
lap whil
e the vehicle is in motion.
● Never transport objects on the front pas-
senger se
at. In the event of sudden braking
and manoeuvres, the objects may end up in
the airbag deployment space and fly uncon-
trollably around the interior if the airbag is
activated.
● Occupants of the front and rear seats must
never carr
y any other people, pets or objects
in the deployment space between them and
the airbags. Make sure children and other
passengers also respect this recommenda-
tion. WARNING
The airbag system provides protection for
one acc ident

only. If they have been de-
ployed, they must be replaced. ●
Ens ur

e deployed airbags and the system
components involved are immediately re-
placed with new, SEAT-approved components
for the vehicle.
● Have any repairs or modifications carried
out at a s
pecialised workshop. Specialised
workshops have the necessary tools, diag-
nostics equipment, repair information and
qualified personnel.
● Never fit recycled or reused airbag compo-
nents in
your vehicle.
● Never modify the airbag system compo-
nents. WARNING
If the airbags are triggered, a fine dust is pro-
duced. Thi

s is normal and it is not an indica-
tion of fire in the vehicle.
● This fine dust may irritate the skin and eyes
and cause br
eathing difficulties, particularly
in people suffering from or who have suffered
from asthma or other illnesses of the respira-
tory tract. To reduce breathing difficulties,
get out of the vehicle and open and doors and
windows to breath in fresh air.
● Should you touch the dust, wash your
hands
and face using a mild soap and water
before you eat.
● Prevent the dust from affecting the eyes or
open wound
s.
● Rinse your eyes with water if you have dust
in them. WARNING
Solvents cause the surfaces of the airbag
modul e

s to become porous. If an airbag is ac-
cidentally triggered, the detachment of plas-
tic parts could cause serious injury.
● Never clean the dash panel and the surfa-
ces
of the airbag modules with cleaners con-
taining solvents. Description of airbag system
