›› page 59 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 58. 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 modules and belt tensioners may con-
tain per c

hlorate. Observe the legal require-
ments for their disposal. 58

Safety
●
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

wards and release the lever. The turn signal
will flash 3 times.
The convenience indicators can be deactiva-
ted at a Specialised workshop. WARNING
Improper or lack of use of the turn signals, or
for g

etting to deactivate them can confuse
other road users. This could result in a seri-
ous accident.
● Always give warning when you are going to
chan
ge lane, overtake or when turning, acti-
vating the turn signal in good time.
● As soon as you have finished changing
lane, ov
ertaking or turning, switch the turn
signal off. WARNING
Incorrect use of the headlights may cause ac-
cident s

and serious injury, as the main beam
may distract or dazzle other drivers. Note
● If the c on

venience turn signals are operat-

carry on wiping at the same level when the
ignition is switched back on. Ice, snow and
other obstacles may damage the windscreen
wiper and the respective motor.
● If necessary, remove snow and ice from the
winds

● Carefully lift the frozen windscreen wipers
from the gla
ss. SEAT recommends a de-icer
spray for this operation. Note
● The wind s

creen wipers will only work when
the ignition is switched on.
● The interval wipe speed varies according to
the vehic
le speed. The faster the vehicle is moving, the more often the windscreen is

lfunction of the rain and light sensor
Some examp
les of possible causes of mal-
functions and mistaken readings in the area
of reference surface ››› Fig. 115 1 of the rain
and light sen
sor:
● W

indscreen wiper blades in poor condi-
tion: the presenc
e of a film or strips of water
due to the poor condition of the wiper blades
can lead to the windscreen blade function
possibly being prolonged, or the wipe inter-
vals may get shorter or the wipe may happen
to be quick and continuous.
● Insects: the impact of
gnats/mosquitoes
on the windscreen can lead to the wind-
screen wiper operation starting up.
● Salt traces: in winter it
is possible that the
windscreen wipers may run longer than usual
due to the presence of salt traces on the al-
most dry windscreen.
● Dirt: the presence of dry dust, wax, protec-
tive fi
lms (lotus effect), remnant of detergent
(from the car wash tunnel), etc., on the wind-
screen can possibly lead to the rain and light
sensor reacting in a more sensitive way, later,
slower, or that it may not react at all.
● Cracked windscreen: the impact of
a stone
may make the windscreen wipers to carry out
a wipe cycle if the rain and light sensor is ac-
tivated. Subsequently, the sensor detects
that the reference surface has been reduced
and adapts. The behaviour of the sensor acti- vation can vary based on the size of the im-
pact.
C

lean the reference surface of rain and light
sensor 1 regularly and check that the wind-
s c
r

een wiper blades are not damaged. CAUTION
The rain and light sensor may not always de-
tect the pr

ecipitation accurately enough and
connect the windscreen wipers properly.
● If necessary, connect the wipers manually
and appropri
ately when water on the wind-
screen obstructs visibility. Note
It is recommended using a windscreen clean-
ing pr oduct

that may contain alcohol to re-
move the remnant of wax or polish. 110

Operation
●
Prior to u s
ing the seat heating, be certain
that the seat cushion is dry.
● Avoid sitting down with damp or wet cloth-
ing.
● Do not p

lace damp or wet objects or gar-
ments on t
op of the seat.
● Do not spill liquids on the seat. CAUTION
● To av oid d

amaging the heating compo-
nents, please refrain from kneeling on the
seats or applying excessive pressure to a sin-
gle point of the seat cushion and backrest.
● If liquids are spilled, sharps objects are left
or insu
lating materials are placed (such as a
covering or child seat), this can manage to
damage the seat heating.
● In any odour were noted, disconnect the
seat he
ating immediately and have the unit
inspected by a specialised workshop. For the sake of the environment
The seat heating must only remain connected
when it i s

necessary. Otherwise, it incurs an
unnecessary waste of fuel. Transport and practical

sporting objects
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
The driving behaviour and braking ability

ge when transporting heavy and large
objects.
● Adjust your speed and driving style to visi-
bility

● Accelerate gently and carefully.
● Avoid sudden braking and manoeuvres.
● Brake early. 114

Driver assistance systems
CAUTION
SEAT does not accept liability for any damage
to the v
ehicle due to the use of a lower quali-
ty fuel, an inadequate service or the non-
availability of genuine spare parts. Driving along flooded roadways
To prevent damage to the vehicle when driv-
ing thr
ough w

ater, for example, along a floo-
ded road, please observe the following:
● Check the depth of the water before enter-
ing the flooded z

one. The water should never
come above the lower edge of the bodywork
››› .
● Do not drive faster than a pedestrian.
● Do not stop in the water, use reverse gear
or sw it
c

h off the engine.
● Oncoming traffic will cause waves which
raise the l
evel of the water, making it difficult
to cross the water.
● Disconnect the Start-Stop system whenever
cro
ssing water. WARNING
When driving through water, mud, melted
sno w

, etc., please remember that due to
damp or frozen brake discs and shoes in win-
ter, the braking effect may be delayed, there-
fore the required braking distance is greater. ●
“Dry the br

akes and remove ice” by braking
carefully. Ensure that you are not endanger-
ing other road-users or breaking traffic regu-
lations in the process.
● After driving through water, avoid sudden
sharp manoeu
vres. CAUTION
● Driv ing thr

ough flooded areas may severely
damage vehicle components such as the en-
gine, transmission, drive train or electrical
system.
● Never drive through salt water as salt cau-
ses c
orrosion. Always rinse any parts of the
vehicle which have been in contact with salt
water. Driver assistance systems

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. » 153
