2017 Seat Arona ECU

Seat belts
The seat belts are equipped with an automat-
ic r
etr
actor on the shoulder strap. Full free-
dom of movement is permitted when the
shoulder belt is pulled slowly. However, dur-
ing sudden braking, during travel in steep
areas or bends and during acceleration, the
automatic retractor on the shoulder belt is
locked.
The automatic belt retractors on the front
seats are fitted with seat belt tensioners

Releasing the seat belt ● Press the red button on the belt buckle
›››
Fig. 100. The latch plate is released and
springs out ››› .
● Guide the belt back by hand so that it rolls
up e a
s

ily and the trim is not damaged.
Positioning seat belts
Seat belts offer their maximum protection on-
ly when they are properly positioned. WARNING
● The seat belt

s offer best protection only
when the backrests are in an upright position
and the seat belts have been fastened prop-
erly.
● Never put the latch plate in the buckle of
another seat. If
you do this, the seat belt will
not protect you properly and the risk of injury
is increased. ●
Never u nb

uckle a seat belt while the vehi-
cle is in motion. If you do, you increase the
risk of sustaining severe or fatal injuries.
● An incorrectly worn seat belt can cause se-
vere injurie
s in the event of an accident.
● The shoulder part of the seat belt must lie
on the centre of
the shoulder, never across
the neck. The seat belt must lie flat and fit
comfortably on the torso
● 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, never across the stomach, and always
lie flat so that no pressure is exerted on the
abdomen ››› Fig. 101.
● Always engage the retractor lock when you
are securin
g a child seat in group 0, 0+ or 1

 page 20 The seat belts for the front and side rear oc-
cupants

are equipped with belt tensioners.
The belt tensioners are activated by sensors,
although only in severe head-on and lateral
collisions. This retracts and tightens the seat
belts, reducing the forward motion of the oc-
cupants.
The belt tensioners will not be triggered in
the event of minor collisions, if the vehicle
overturns, or in accidents where no major
forces act on the vehicle. Note
● If the se at

belt tensioners are triggered, a
fine dust is produced. This is normal and it is
not an indication of fire in the vehicle.
● The relevant safety requirements must be
obser
ved when the vehicle or components of
the system are scrapped. Specialised work-
shops are familiar with these regulations,
which are also available to you. Service and disposal of belt tension-

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 79. 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) (see
www.seat.com). These systems have been especially de-
signed and ap
pr

oved, complying with the
ECE-R44. regulation.
SEAT recommends securing the child seats
shown on the website as described below:
● Child seats in the opposite direction of
travel
(group 0+): ISOFIX and support bracket
(Peke G0 Plus + ISOFIX Base (RWF)).
● Child seats in the direction of travel (group
1): ISOFIX and T
op Tether (Peke G1 ISOFIX
DUO Plus).
● Child seats in the direction of travel (group
2): seat belt
and ISOFIX (RÖMER KIDFIX XP ©
).
● Child seats in the direction of travel (group
3): with seat
belt (TAKATA MAXI PLUS ©
).
Follow the manufacturer's instructions and
observe any statutory requirements when in-
stalling and using child seats. Always read
and note ››› page 88.
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 23. Read and always observe the safety informa-
tion included in the fo

llowing chapters:
● Safety distance with respect to the passen-
ger airbag ›

›› page 82.
● Objects between the passenger and the
pas
senger side airbag ››› in Front airbags
on p ag
e 84
.
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 86.
When transporting children, use a child seat
suitable for the age and size of each child
››› page 90. 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. 88

Transporting children safely
●
Never in s
tall a child seat facing backwards
on the front passenger 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 86, Deacti-
vation of front passenger front airbag*. If the
passenger seat has a height adjustment op-
tion, move it to the rearmost and highest po-
sition. If it is a fixed seat, it should be moved
to the rearmost position possible.
● 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. Do
not forget to reconnect the airbag when an
adult wants to sit in the front passenger seat.
● 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 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
chi
l

d 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 77.
● Only one child may occupy a child seat
›››

page 89, Child seats.
● When a child seat is mounted in the rear
seats, the door c
hild-proof lock should be ac-
tivated ››› page 132. Child seats

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). 89
