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.

users.
● Stop the vehicle safely as soon as possible.
Park the
vehicle a safe distance from sur-
rounding traffic to lock all the doors in case of
an emergency. Turn on the hazard warning
lights to warn other road users.
● Never leave children or disabled people
alone in the v
