2017 Seat Leon 5D airbag

Safety
position must always be maintained with
seat
belt
s fastened while travelling.
● In a side-on collision the side airbags will
not work
if the sensors do not correctly meas-
ure the pressure increase on the interior of
the doors, due to air escaping through the
areas with holes or openings in the door pan-
el.
● Never drive if the interior door panels have
been remov
ed or if the panels have not been
correctly fitted.
● Never drive the vehicle if the loudspeakers
in the door panels
have been removed, un-
less the holes left by the loudspeakers have
been closed properly.
● Always check that the openings are closed
or cov
ered if loudspeakers or other equip-
ment are fitted inside the door panels.
● Occupants of the outer seats must never
carry
any objects or pets in the deployment
space between them and the airbags, or al-
low children or other passengers to travel in
this position. It is also important not to at-
tach any accessories (such as cup holders) to
the doors. This would impair the protection
offered by the side airbags.
● The built-in coat hooks should be used only
for lightweight
clothing. Do not leave any
heavy or sharp-edged objects in the pockets.
● Great forces, such as hard blows or kicks,
must
not be exerted upon the backrest bol-
ster because the system may be damaged. In
this case, the side airbags would not be trig-
gered. ●
Under no cir c

umstances should protective
covers be fitted over seats with side airbags
unless the covers have been approved for use
in your vehicle. Because the airbag deploys
from the side of the backrest, the use of con-
ventional seat covers would obstruct the side
airbag, seriously reducing the airbag's effec-
tiveness.
● Any damage to the original seat upholstery
or around the se
ams of the side airbag units
must be repaired immediately by a special-
ised workshop.
● The airbags provide protection for just one
accident; r
eplace them once they have de-
ployed.
● Any work on the side airbag system or re-
mova
l and installation of the airbag compo-
nents for other repairs (such as removal of
the front seat) should only be performed by a
specialised workshop. Otherwise, faults may
occur during the airbag system operation.
● Do not attempt to modify components of
the airbag sys
tem in any way. Head-protection airbags*

 page 24. WARNING
● In order f or the he

ad-protection airbags to
provide their maximum protection, the pre- scribed sitting position must always be main-
tained w
ith se

at belts fastened while travel-
ling.
● For safety reasons, the curtain airbag must
be disab
led in those vehicles fitted with a
screen dividing the interior of the vehicle.
See your technical service to make this ad-
justment.
● There must be no other persons, animals or
obj
ects between the occupants of the outer
seats and the deployment space of the head-
protection airbags so that the head-protec-
tion airbag can deploy completely without re-
striction and provide the greatest possible
protection. Therefore, sun blinds which have
not been expressly approved for use in your
vehicle may not be attached to the side win-
dows
● The built-in coat hooks should be used only
for lightweight
clothing. Do not leave any
heavy or sharp-edged objects in the pockets.
Please, do not hang the clothes on coat hang-
ers.
● The airbags provide protection for just one
accident; r
eplace them once they have de-
ployed.
● Any work on the head-protection airbag
syst
em or removal and installation of the air-
bag components for other repairs (such as re-
moval of the roof lining) should only be per-
formed by a specialised workshop. Other-
wise, faults may occur during the airbag sys-
tem operation.
● Do not attempt to modify components of
the airbag sys
tem in any way.88

Airbag system
●
The side and he a
d airbags are managed
through sensors located in the interior of the
front doors. To ensure the correct operation of
the side and curtain airbags neither the
doors nor the door panels should be modified
in any way (e.g. fitting loudspeakers). If the
front door is damaged, the airbag system
may not work correctly. All work carried out
on the front door must be done in a special-
ised workshop. Deactivating airbags

Transporting children safely
Transporting children safely Saf ety
f
or children
Introduction For safety reasons, as we have learned from
acc
ident

statistics, we recommend that chil-
dren under 12 years of age travel in the rear
seats. Depending on their age, height and
weight, children travelling in rear seats must
use a child seat or a seat belt. For safety rea-
sons, the child seat should be installed in the
rear seat, behind the front passenger seat or
in the centre back seat.
The physical laws involved and the forces
acting in a collision apply also to children
››› page 82. But unlike adults, children do not
have fully developed muscle and bone struc-
tures. This means that children are subject to
a greater risk of injury.
To reduce the risk of injuries, children must
always use special child restraint systems
when travelling in the vehicle.
We recommend the use of child safety prod-
ucts from the SEAT Original Accessories Pro-
gramme, which includes systems for all ages
made by “Peke” (not for all countries).
These systems have been especially de-
signed and approved, complying with the
ECE-R44. regulation. Follow the manufacturer's instructions and
ob
ser

ve any statutory requirements when in-
stalling and using child seats. Always read
and note ››› page 91.
We recommend you always carry the manu-
facturer's Child Seat Instruction Manual to-
gether with the on-board documentation.
Important information regarding the
front p
assenger's airbag Read the additional information carefully
› ›
›

 page 25.
Read and always observe the safety informa-
tion included in the following chapters:
● Safety distance with respect to the passen-
ger airbag ›

›› page 85.
● Objects between the passenger and the
pas
senger side airbag ››› in Front airbags
on p ag
e 87
.
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 89.
When transporting children, use a child seat
suitable for the age and size of each child
››› page 92. 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 90. 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. » 91

Safety
●
Never ho l
d children or babies on your lap,
this can 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 to 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 80.
● Only one child may occupy a child seat
›››

page 92, Child seats. ●
When a chi l

d seat is mounted in the rear
seats, the door child-proof lock should be ac-
tivated ››› page 133. Child seats

 page 25. WARNING
When travelling, children must be secured in
the v ehic

le with a restraint system suitable
for age, weight and size.
● Read and always observe information and
warning
s concerning the use of child seats
››› page 91. WARNING
The retaining rings are designed only for use
with “ISOFIX” and T op

Tether* system child
seats.
● Never secure other child seats that do not
have the “ISOFIX” or T
op Tether* system, or
retaining belts or objects to the fastening
rings - this can result in potentially fatal inju-
ries to the child.
● Ensure that the child seat is secured cor-
rectly u
sing the “ISOFIX” and Top Tether* se-
curing rings. WARNING
An undue installation of the safety seat will
incr e

ase the risk of injury in the event of a
crash.
● Never tie the retainer strap to a hook in the
luggag
e compartment.
● Never secure or tie luggage or other items
to the low
er anchorages (ISOFIX) or the upper
ones (Top Tether). Categorisation of child seats into
gr
oup
s Use only child seats that are officially ap-
pr
o
v

ed and suitable for the child.
Child seats are subject to the regulation ECE-
R 44. ECE-R stands for: Economic Commis-
sion for Europe Regulation.
The child seats are grouped into 5 catego-
ries:
Group 0: Up to 10 kg (up to around 9
months)
Group 0+: Up to 13 kg (up to around 18
months)
Group 1: from 9 to 18 kg (up to approx. 4
years old)
Group 2: from 15 to 25 kg (up to approx. 7
years old)
