● The l ap p
ar
t of the seat belt must lie across
the pelvis, never across the stomach.
● The seat belt must lie flat and fit comforta-
bly. P
ull the belt tight if necessary to take up
any slack.
In the case of pregnant women , the seat belt
must lie evenly across the chest and as low
as possible over the pelvis, never across the
stomach and must be worn properly at all
times during the pregnancy ››› Fig. 73.
Adapting the position of the belt webbing to
your size
The seat belt can be adapted using the fol-
lowing equipment:
● Front seat height adjustment. WARNING
An incorrectly worn seat belt web can cause
sever e or f

atal injuries in the event of an acci-
dent.
● The seat belt cannot offer its full protection
unl
ess the seat backrest is in an upright posi-
tion and the seat belt is worn correctly, ac-
cording to your size.
● Unbuckling your seat belt while the vehicle
is in motion c
an cause severe or fatal injuries
in the event of an accident or sudden braking.
● The seat belt itself or a loose seat belt can
cause sev
ere injuries if the belt moves from hard areas of the body to soft areas (e.g. the
st
om

ach).
● The shoulder part of the seat belt must lie
on the centre of
the shoulder, never across
the neck or the arm.
● The seat belt must lie flat and fit comforta-
bly on the t
orso
● The lap part of the seat belt must lie across
the pelvis, nev
er across the stomach. The
seat belt must lie flat and fit comfortably on
the pelvis Pull the belt tight if necessary to
take up any slack.
● For pregnant women, the lap part of the
seat belt
must lie as low as possible over the
pelvis and always lie flat, “surrounding” the
stomach.
● Do not twist the seat belt while it is fas-
tened.
● Never p

ull the seat belt away from your
body us
ing your hand.
● Do not lie the seat belt across rigid or frag-
ile o
bjects, e.g. glasses, pens or keys.
● Never use seat belt clips, retaining rings or
simil
ar instruments to alter the position of
the belt webbing. Note
If your physical constitution prevents you
from m aint

aining the correct position of the
belt webbing, contact a specialised workshop
for help with any special devices to ensure
the optimum protection of the seat belt and airbag. SEAT recommends taking your car in
for t
ec

hnical service. Seat belt tensioners

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 »

Safety
●
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

Ma

lfunction of the rain and light sensor
Some examples of possible causes of faults
and mistaken readings on the reference sur- face
››› Fig. 115 1 of the rain and light sen-
sor:
● Windscreen wiper blades damaged: The
pr e
senc

e of a film or strips of water caused
by damaged blades may cause the wind-
screen wipers to be slower taking effect,
shorten wiping intervals or cause wiping to
be fast and continuous.
● Insects: mosquitoes impacting the wind-
sc
reen can activate the windscreen wiper.
● Traces of salt: in winter
, the windscreen
wiper may work for longer than usual due to
the presence of traces of salt on the almost
dry windscreen.
● Dirt: the presence of dry dust, wax, coating
films
(Lotus effect) or traces of detergent (car
wash) etc., on the windscreen may cause the
rain and light sensor to be less sensitive, re-
act more slowly, later or not at all.
● Cracked windscreen: the impact of
a stone
will trigger a single wipe cycle if the rain and
light sensor is activated. Subsequently, the
sensor detects the reduction in the reference
surface area and adapts accordingly. The be-
haviour of the sensor will vary with the size of
the damage.
Clean the reference surface area of the rain
and light sensor 1 regularly and check that
the w ind
s

creen wiper blades have not been
damaged. CAUTION
The rain and light sensor does not always de-
tect r

ainfall with sufficient accuracy so does
not always switch on the windscreen wiper at
the right moment.
● If necessary, switch on the windscreen wip-
ers m
anually when water on the windscreen
obstructs visibility. Note
We recommend the use of a glass cleaning
product c

ontaining alcohol to remove traces
of wax or polish. Mirror

Introduction Always transport heavy loads in the luggage
comp
ar

tment and place the seat backs in a
vertical position. Never overload the vehicle.
Both the carrying capacity as well as the dis-
tribution of the load in the vehicle affect driv-
ing behaviour and braking ability ››› .
WARNING
Unsecured or incorrectly secured objects can
cau se seriou

s injury in case of a sudden ma-
noeuvring or breaking or in case of an acci-
dent. This is especially true when objects are
struck by a detonating airbag and fired
through the vehicle interior. To reduce the
risks, please note the following:
● Secure all objects in the vehicle. Always
keep equipment and he
avy objects in the lug-
gage compartment.
● Always secure objects with suitable rope or
sling
s so that they cannot enter the deploy-
ment areas around the frontal or side airbags
in case of sudden braking or an accident.
● Always ensure that objects inside the vehi-
cle c
annot move into the deployment area of
the bags while driving. ●
Whil e driv

ing, always keep object compart-
ments closed.
● Remove all objects from the front passen-
ger seat
when it is folded down. When the
seat backrest is folded down, it presses on
small and light objects and these are detec-
ted by the weight sensor on the seat; this
sends false information to the airbag control
unit.
● While the backrest of the front passenger
seat i
s folded, the frontal airbag must remain
disconnected and the PASSENGER AIRBAG
OFF  light on.
● Objects secured in the vehicle should never
be plac
ed in such a way as to make passen-
gers sit in an incorrect position.
● If secured objects occupy a seat, this seat
should not
be occupied or used by anyone. WARNING

● Accelerate gently and carefully.
● Avoid sudden braking and manoeuvres.
● Brake early. Transporting the load
Secure all objects in the vehicle
● Distribute the load throughout the vehicle
and on the roof a

s uniformly as possible.
● Transport heavy objects as far forward as
poss
ible in the luggage compartment and
lock the seat backs in the vertical position.
● Check the headlight adjustment

g distance warning sys-
tem*
Introduction The parking distance warning system assists
the driver when p
ark

ing. If the rear of the ve-
hicle is approaching an obstacle, an intermit-
tent audible warning is emitted. The shorter
the distance, the shorter the intervals be-
tween tones. If the vehicle is too close to the
obstacle, the audible warning becomes con-
stant.
If you continue to approach an obstacle when
the sound is continuous, this means the sys-
tem can no longer measure the distance.
Sensors situated on the rear bumper transmit
and receive ultrasound. Using the ultrasound
signal (transmission, reflection from the ob-
stacles and reception), this system continu-
ously calculates the distance between the
bumper and the obstacle. WARNING
The parking distance warning system cannot
rep l

ace the driver's assessment of the situa-
tion.
● The sensors have blind spots in which ob-
stac
les and people are not registered. ●
Alw a

ys observe the area around the vehi-
cle, as the sensors do not always detect
small children, animals or objects.
● The surface of certain objects and some
clothing do not
reflect the ultrasound signals
from the parking distance system. The sys-
tem cannot detect or incorrectly detects
these objects and people wearing these
types of clothes.
● External sound sources can affect the park-
ing dis
tance aid signals. In this case, under
certain circumstances, people and objects
will not be detected. CAUTION
● The sensor s

may not always be able to de-
tect objects such as trailer draw bars, thin
rails, fences, posts, trees and open boots,
etc. This could result in damage to your car.
● Although the parking distance warning sys-
tem detect
s and warns of the presence of an
obstacle, the obstacle could disappear from
the angle of measurement of the sensors if it
is too high or low and the system would no
longer show it. Therefore, it will not warn you
of these objects. Ignoring the warnings of the
parking sensor system could cause consider-
able damage to the vehicle.
● The bumper sensors may become damaged
or misa
ligned, for example, when parking.
● To ensure that the system works properly,
the bumper sensor
s must be kept clean, free
of ice and snow and uncovered. » 153
