Safe driving
WARNING
Incorrect seat adjustment may lead to acci-
dents and sev
ere injuries.
● Only adjust the seats when the vehicle is
station
ary, as the seats could move unex-
pectedly while the vehicle is in motion and
you could lose control of the vehicle. Further-
more, an incorrect position is adopted when
adjusting the seat.
● Only adjust the height, seat backrest and
forw
ards or backwards position of the seat
when there is nobody in the seat adjustment
area.
● There must be no objects blocking the front
seat a
djustment area. Adjusting the rear head restraints
Fig. 66
Adjusting the rear head restraints All seats are equipped with a head restraint. The front seat head restraints are integrated
in the b
ac
k
rests and adjusting them is not
possible.
Adjusting height
● Push the head restraint up or down in the
direction of the arr
ow with the button press-
ed ››› Fig. 66 1
› ›› .
● The head restraint must engage securely in
po s
ition.
C
orrect adjustment of head restraints
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 lev-
el as the top of your head and under no cir-
cumstances below eye level. Keep the back
of your neck as close as possible to the head
restraint.
Adjusting the head restraint for short people
Set the head restraint in the first anchorage
position, even if your head is below its upper
edge. When the head restraint is at its low-
est, it is possible that a small gap remains
between it and the seat backrest.
Adjusting the head restraint for tall people
Raise the head restraint completely. WARNING
Travelling with the head restraints removed
or improperly a
djusted increases the risk of
severe or fatal injuries in the event of acci-
dents and sudden braking or manoeuvres.
● Always fit and adjust the head restraint
properly whenev
er a person is occupying a
seat.
● All vehicle occupants must correctly adjust
the head r
estraint according to their height to
reduce the risk of back injuries in the event of
an accident. The upper edge of the head re-
straint must be as close as possible to the
same level as the top of your head and under
no circumstances below eye level. Keep the
back of your neck as close as possible to the
head restraint.
● Never adjust the head restraint while the
vehicl
e is in motion. Pedal area
P ed
a
ls Do not allow floor mats or other objects to
o
b
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. »

Safety
In the event of failure of a brake circuit, the
br ak
e ped
al 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 vehicle. To press the brake pedal down
further will require more force than usual. Seat belts
Wh y
w
ear a set 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. This also applies to other vehicle occupants
when drivin
g in t
own.
● When travelling, children must be secured
in the vehic
le with a child restraint system
suitable for their weight and height and with
the seat belts correctly fastened
››› page 64.
● Instruct your passengers to fasten their
seat belt
s properly before driving off.
● Insert the latch plate into the buckle for the
appropri
ate seat and ensure it is engaged.
Using the latch plate in the buckle of another
seat will not protect you properly and may
cause severe injuries.
● Do not allow liquids or foreign bodies to en-
ter the buc
kle fastenings. This could damage
the buckles and seat belts.
● Never unbuckle your seat belt when the ve-
hicle i
s moving.
● Never allow more than one passenger to
share the s
ame seat belt.
● Never hold children or babies on your lap
sharing the s
ame seat belt.
● Bulky and unbuttoned clothing, such as a
coat
worn over a sweatshirt, impairs the
proper fit and function of the seat belt. WARNING
It is extremely dangerous to drive using dam-
aged se at
belts and could result in serious in-
jury or loss of life. 52

Correct seat belt position
Seat belts offer their maximum protection in
the event of an accident and reduce the risk
of sustaining severe or fatal injuries only
when they are properly positioned. Further-
more, if the webbing is correctly positioned,
the seat belt will hold the vehicle occupants
in the optimum position to ensure the airbag
provides the maximum protection. The seat
belt must therefore always be worn and the
webbing correctly positioned.
Incorrectly worn seat belts can cause severe
or even fatal injuries ››› page 48, Correct po-
sition of the vehicle occupants .
● The shoulder part of the seat belt must lie
on the centre of
the shoulder, never across
the neck or the arm, under the arm or behind
the shoulder.

Airbag system
WARNING
● The seat belt
s and airbags can only provide
maximum protection if the occupants are
seated correctly ››› page 48.
● If a fault has occurred in the airbag system,
have the sy
stem checked immediately by a
specialised workshop. Otherwise, during a
frontal collision the system might not trigger
correctly or may fail to trigger at all. Airbag activation
The airbags deploy extremely rapidly, within
thou
s
andths
of a second, to provide addi-
tional protection in the event of an accident.
A fine dust may develop when the airbag de-
ploys. This is normal and it is not an indica-
tion of fire in the vehicle.
The airbag system is only ready to function
when the ignition is on.
In special accidents instances, several air-
bags may activate at the same time.
In the event of minor head-on and side colli-
sions, rear-end collisions, overturning or roll-
over of the vehicle, airbags do not activate.
Activation factors
The conditions that lead to the airbag system
activating in each situation cannot be gener-
alised. Some factors play an important role,
such as the properties of the object the vehi- cle hits (hard/soft), angle of impact, vehicle
speed, etc
.
Deceleration trajectory is key for airbag acti-
vation.
The control unit analyses the collision trajec-
tory and activates the respective restraint
system.
If the deceleration rate is below the prede-
fined reference value in the control unit the
airbags will not be triggered, even though
the accident may cause extensive damage to
the car.
The following airbags are triggered in seri-
ous head-on collisions ● Driver airbag.
● Front passenger front airbag
The fol
lowing airbags are triggered in seri-
ous side-on collisions
● Front side airbag on the side of the acci-
dent.
● Re
ar side airbag on the side of the acci-
dent.
In an acc
ident with airbag activation:
● the interior lights switch on (if the interior
light swit
ch is in the courtesy light position);
● the hazard warning lights switch on;
● all doors are unlocked; ●
the fuel s
upply to the engine is cut.

The airbag is deployed at high speed in frac-
tions of
a second.
● Always keep the deployment areas of the
front airb
ags vacant.
● Never secure objects to the covers or in the
deployment
area of the airbag modules, e.g.
drink holders or phone supports.
● The deployment space between the front
pas
sengers and the airbags must not in any
case be occupied by other passenger, pets
and objects.
● Never fix any object to the windscreen
above the fr
ont airbag on the front passenger
side.
● Do not alter, cover or stick anything to the
steerin

Transporting children safely Saf ety
f
or children
Introduction Before transporting babies and children in a
chi
l
d seat placed in the front passenger seat,
first completely read the information regard-
ing the airbag system.
This information is extremely important for
driver and passenger safety, particularly that
of babies and children.
SEAT recommends the use of child seats from
the SEAT accessory programme. These child
seats have been designed and tested for use
in SEAT vehicles. You can purchase child
seats with different mountings from a SEAT
dealership. WARNING
Make sure children are properly belted in and
corr ectly
secured to avoid severe or fatal inju-
ries while the vehicle is in motion.
● Never use a rear-facing child seat in the
front p
assenger seat if the front passenger
front airbag is enabled.
● Children up to 12 years old should always
travel
on the rear seat. ●
Chil dr
en must always be protected with an
approved child restraint system suited to
their height and weight.
● Children must assume the proper sitting
position and be pr
operly belted in while trav-
elling.
● Ensure the seat backrest is upright when a
chil
d seat is being used on it.
● Do not allow the child's head or other part
of his
or her body to enter the deployment
area of the side airbags.
● Make sure the belt webbing is correctly
positioned.
● Nev
er hold children or babies on your lap or
in your arms.
● On
ly one child may occupy a child seat.
● Please read and observe the child seat
manufact
urer's handling instructions. WARNING
An empty or loose child seat could fly uncon-
tro l
lably around the vehicle interior and
cause injuries in the event of an accident or
sudden braking.
● When not in use while the vehicle is in mo-
tion, alwa
ys safely secure the child seat or
store it in the luggage compartment. Note
Replace the child seat after an accident, as it
ma y
have invisible damage. Important information regarding the
fr
ont
p
assenger's airbag Read the additional information carefully
›› ›
page 16.
Read and always observe the safety informa-
tion included in the following chapters: ● Safety distance with respect to the passen-
ger airbag ›
›› in Introduction on page 59.
● Objects between the passenger and the
pa s
senger side airbag ››› in Front airbags
on p ag
e 61
.
The passenger 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 63.
When transporting children, use a child seat
suitable for the age and size of each child
››› page 67.

Transporting children safely
WARNING
● If a c hi
ld 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 r
ear-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 p
assenger 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 63. 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 sw
itch 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.
● Never hold children or babies on your lap,
this c
an result in potentially fatal injuries to
the child!
● Never allow a child to be transported in a
vehicl
e without being properly secured, or to
stand up or kneel on a seat while travelling.
In an accident, the child could be flung through the vehicle, causing possibly fatal in-
juries
t
o themselves and to the other vehicle
occupants.
● If children assume an improper sitting posi-
tion when the vehic
le is moving, they expose
themselves to greater risk of injury in the
event of a sudden braking manoeuvre or in an
accident. This is particularly important if the
child is travelling on the front passenger seat
and the airbag system is triggered in an acci-
dent; as this could cause serious injury or
even death.
● A suitable child seat can protect your child!
● Never leave a child alone in the child seat
or inside the
vehicle because depending on
the season, very high temperatures may be
reached inside a parked vehicle, which could
be fatal.
● Children who are less than 1.5 metres tall
must
not wear a normal seat belt without a
child seat, as this could cause injuries to the
abdominal and neck areas during a sudden
braking manoeuvre or in an accident.
● Do not allow the seat belt to become twis-
ted and the seat
belt should be properly in
place ››› page 52.
● Only one child may occupy a child seat
›››
page 67.
● When a child seat is mounted in the rear
seats, the door c
hild-proof lock should be ac-
tivated ››› page 99. Child seats

Child seats with lower anchor points and with
an upper r et
aining strap must be installed in
line with the manufacturer's instructions.
Failure to comply could result in severe inju-
ries.
● Always secure just one r

Use of the child seat on the front pas-
sen g
er se
at1) Transporting children on the front passenger
seat
i
s not permitted in all countries. Further-
more, not all child seats are approved for use
on the front passenger seat. Your SEAT deal-
ership has an updated list of all approved
child seats. Only used child seats that are ap-
proved for each vehicle.
The front airbag on the front passenger side
is highly dangerous for a child. The front pas-
senger seat is life-threatening to a child if he
or she is transported in a rear-facing child
seat.
If a rear-facing child seat is secured to the
front passenger seat, an inflating front airbag
can strike it with such great force that severe
or fatal injuries may result ››› . Therefore,
r e
ar
-facing child seats must never be placed
on the front passenger seat when the front
passenger front airbag is enabled.
Only use a rear-facing child seat on the front
passenger seat if the front passenger front
airbag is disabled. When it is disabled, the
yellow ›››
page 58 con-
trol lamp on the dash panel will be lit. If you
cannot disable the front passenger front air- bag and it remains activated, it is forbidden
to tran
sport children on the front passenger
seat ››› .
Thin g
s
to note if using a child seat on the
front passenger seat:
● The front passenger front airbag must
be
disabled when using a rear-facing child
seat ››› page 58.
● The seat backrest of the front passenger
seat mu
st be upright.
● The front passenger seat must be moved as
far bac
k as possible.
● A height-adjustable front passenger seat
must
be raised to its highest point.
Suitable child seats
The child seat must be authorised by the
manufacturer especially for use on a front
passenger seat with a front or side airbag.
Universal seats for children can be fitted in
the front passenger seat, in groups 0, 0+, 1,
2 or 3 according to the ECE-R 44 regulation. WARNING
If a child seat is mounted on the front passen-
ger se at, the ri
sk of the child sustaining se- vere or fatal injuries in the event of an acci-
dent inc
r
eases. Rear-facing child seats must
never be mounted on the front passenger
seat when the front passenger front airbag is
enabled. This is life-threatening to the child
should the front airbag deploy, as the child
seat would be struck by the inflated airbag
and thrown against the seat backrest. WARNING
If, in exceptional circumstances, a child must
be tr ans
ported in a rear-facing child seat on
the front passenger seat, strictly observe the
following:
● Always disable the front passenger front
airbag and le
ave it disabled.
● The child seat must be approved by the
manufact
urer for use on a front passenger
seat with front and side airbag.
● Follow the installation instructions of the
chil
d seat manufacturer and observe the
warnings.
● Move the front passenger seat as far back
as po
ssible and adjust it to its highest posi-
tion to keep as far away as possible from the
front airbag.
● Move the seat backrest to the upright posi-
tion. 1)
Compliance with current national legislation and
the manuf act
urer's instructions is required when us-
ing or installing child seats.
