Safety

●

Any work on the head-protection airbag

system or removal and installation of the
airbag components for other repairs (such
as removal of the roof lining) should only
be performed by a specialised workshop.
Otherwise, faults may occur during the air-
bag system operation.

●

The side and head airbags are managed

through sensors located in the interior of
the front doors. To ensure the correct oper-
ation of the side and curtain airbags nei-
ther the doors nor the door panels should
be modified in any way (e.g. fitting loud-
speakers). 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 specialised workshop.

Safety for children

Introduction

For safety reasons, as we have learned from
accident 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 16

. 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 al-
ways 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 approved, 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 trav-

el (group 0+): ISOFIX and support foot (RÖ-
MER BABY SAFE PLUS SHR II + ISOFIX BASE /
PEKE G0 I-SIZE + I-SIZE BASE).

●

Child seats in the direction of travel (group

1): ISOFIX and Top Tether (RÖMER DUO PLUS
+ TOP TETHER / PEKE G1 TRIFIX I-SIZE).

●

Child seats facing the direction of travel

(group 2): safety belt and ISOFIX (RÖMER
KIDFIX XP).

●

Child seats facing the direction of travel

(group 3): safety belt and ISOFIX (RÖMER
KIDFIX XP).

Follow the manufacturer's instructions and
observe any statutory requirements when in-
stalling and using child seats. Always read
and note

›››

page 28

We recommend you always carry the manu-
facturer's Child Seat Instruction Manual to-
gether with the on-board documentation.

Transporting children safely

Child seats group classification

Fig. 20

Examples of child seats.

Use only child seats that are officially ap-
proved and suitable for the child.

Child seats are subject to the regulation ECE-
R 44 or ECE-R 129. ECE-R stands for: Eco-
nomic Commission for Europe Regulation.

Child seats by weight group

The child seats are grouped into 5 catego-
ries:

Age group

Weight of the child

Group 0

Up to 10 kg

Group 0+

Up to 13 kg

Group 1

From 9 to 18 kg

Group 2

From 15 to 25 kg

Group 3

From 22 to 36 kg

Child seats that have been tested and ap-
proved under the ECE-R 44 or ECE-R 129
standard bear the test mark ECE-R 44 or
ECE-R 129 on the seat (the letter E in a circle
with the test number below it).

Follow the manufacturer's instructions and
observe any statutory requirements when in-
stalling and using child seats.

We recommend you to always include the
manufacturer's Child Seat Instruction Manual
together with the on-board documentation.

SEAT recommends you use child seats from
the

Original Accessories Catalogue

. These

child seats have been designed and tested
for use in SEAT vehicles. You can find the right
child seat for your model and age group at
SEAT dealers.

Child seats by approval category

Child seats may have the approval category
of universal, semi-universal, vehicle specific
(all according to the ECE-R 44 standard) or i-
Size (according to the ECE-R 129 standard).

●

Universal

: child seats with universal appro-

val can be installed in all vehicles. There is no
need to consult any list of models. In the case
of universal approval for ISOFIX, the child
seat is additionally provided with a Top Tether
belt.

●

Semi-universal

: semi-universal approval,

in addition to the standard requirements of

universal approval, requires safety devices to
lock the child seat, which require additional
testing. Child seats with semi-universal ap-
proval include a list of vehicle models for
which they can be installed.

●

Vehicle-specific

: vehicle-specific approval

requires a dynamic test of the child seat for
each vehicle model separately. Child seats
with vehicle-specific approval also include a
list of vehicle models for which they can be
installed.

●

i-Size

: child seats with i-Size approval must

meet the requirements prescribed in the ECE-
R 129 standard in relation to installation and
safety. Child seat manufacturers can tell you
which seats have i-Size approval for this vehi-
cle.

Warnings about fitting a child seat

Take the following general warnings into ac-
count if you are going to fit a child seat. They
are valid for all child seats regardless of their
attachment system.

●

Please read and follow the child seat man-

ufacturer's operating instructions.

●

The child seat should preferably be fitted to

the rear seat behind the front passenger seat
so that the child can exit the vehicle on the
pavement side.

●

Set the height of the seat belt such that it

adapts to the child seat naturally, without
twisting. The lowest position of the seat belt
height regulator must be used with rear-fac-
ing child seats.

●

To correctly use a child seat in the back,

the front backrest must be adjusted so that
there is no contact with the child seat in the
back in the case that it goes opposite to the
direction of the car. In the case of front facing
restraint systems, the front backrest must be
adjusted so that there is no contact with the
child's feet.

●

If a semi-universal type chair is to be instal-

led, in which the method of attachment to the
car is through the seat belt and support

bracket, it should never be installed in the
central rear seat as the ground clearance is
lower than in other places and the support
bracket will not allow the seat to remain suffi-
ciently stable.

●

When fitting a child seat on the front pas-

senger seat, the seat must be moved back-
wards as far as possible and placed in the
highest position. The backrest must also be
put in a vertical position

Important information about the front pas-
senger front airbag

A sticker with important information about the
passenger airbag is located on the passeng-
er's sun visor and/or on the passenger side
door frame

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

Compliance with current national legislation

and the manufacturer's instructions is required
when using or installing child seats.

Transporting children safely

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 27

WARNING

●

If a child 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 rear-facing child seat and project
it with great force against the door, the roof
or the backrest.

●

Never install a child seat facing back-

wards on the front passenger seat unless
the front passenger front airbag has been
disabled. Risk of potentially fatal injuries to
the child! However, if necessary, the front
passenger front airbag must be deactiva-
ted

›››

page 23

. If the passenger seat has a

height adjustment option, move it to the
highest, most upright position. 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 switch to deactivate the airbag,
the vehicle must be taken to a technical
service. Do not forget to reconnect the air-
bag when an adult wants to sit in the front
passenger seat.

●

Never allow a child to be transported in a

vehicle without being properly secured, or
to stand up or kneel on a seat while travel-
ling. In an accident, the child could be flung
through the vehicle, causing possibly fatal
injuries to themselves and to the other vehi-
cle occupants.

●

Never leave a child alone in the child seat

or in the vehicle.

●

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 acci-
dent.

●

When a child seat is mounted in the rear

seats, the door child-proof lock should be
activated

›››

page 73

Attachment systems

Depending on the country, different attach-
ment systems are used for safely installing
child seats.

Attachment systems overview

●

ISOFIX

: ISOFIX is a standardised attach-

ment system allowing quick and safe attach-
ment of child seats in the vehicle. ISOFIX at-
tachment establishes a rigid connection be-
tween the child seat and the car body.

The child seat has two rigid attachment clips,
called connectors. These connectors are fit-
ted into the ISOFIX attachment rings found
between the seat cushion and the backrest
of the vehicle's back seat (on the sides). ISO-
FIX attachment systems are used mainly in
Europe

›››

page 30

. If necessary, ISOFIX at-

tachment may have to be supplemented with
a Top Tether belt or a support bracket.

●

Automatic three-point seat belt

. When-

ever possible, it is preferable to attach the
child seats with the ISOFIX system rather than
attaching them with an automatic three-point
seat belt

›››

page 33

Additional attachment:

●

Top Tether

: the Top Tether belt is guided

over the back of the rear seat and attached
to an anchor point with a hook. Anchor points
are located at the back of the rear seat back-
rest on the boot side

›››

page 32

. The rings

for retaining the Top Tether belt are marked
with an anchor symbol.

●

Support bracket

: some child seats rest on

the floor of the vehicle with a support bracket.
The support bracket prevents the child seat

Safety

from tipping forward in the event of impact.
Child seats fitted with a support bracket
should only be used in the passenger seat
and side rear seats

›››

. For the assembly of

this type of seat you should also consult the
list of approved vehicles for this assembly,
available in the instructions for child restraint
systems.

Recommended systems for attaching
child seats

SEAT recommends attaching child seats as
follows:

●

Baby carriers or child seats in the oppo-

site direction of travel:

ISOFIX and support

bracket or i-Size.

●

Child seats in the direction of travel:

ISO-

FIX and Top Tether.

WARNING

Incorrect use of the support bracket can
cause serious or fatal injury.

●

Make sure the support bracket is correct-

ly and safely installed.

use with “ISOFIX” and Top Tether system
child seats.

●

Never secure other child seats that do

not have the “ISOFIX” or Top Tether system,
or safety belts or any other objects to the
securing rings – as this can result in poten-
tially fatal injuries to the child.

●

Ensure that the child seat is correctly se-

cured to the “ISOFIX” and Top Tether secur-
ing rings.

Top Tether securing belts

Fig. 25

Back of the rear seats: Top Tether ring

concealed underneath a cut in the carpet.

Child seats with the Top Tether system come
with a strap for securing the seat to the vehi-
cle anchor point, located at the back of the
rear seat backrest and provide greater re-
straint.

The objective of this strap is to reduce for-
ward movements of the child seat in a crash,
to reduce the risk of injuries to the head from
hitting the inside of the vehicle.

Using the Top Tether in rear-facing moun-
ted seats

Currently, there are very few rear-facing child
safety seats that have Top Tether. Please
carefully read and follow the seat manufac-
turer instructions to learn the proper way to
install the Top Tether strap.

Securing the retainer strap

●

Follow the manufacturer's instructions to

deploy the child seat Top Tether retaining
strap.

●

Place the belt under the headrest of the

back seat (depending on the instructions of
the chair itself, lift or remove the headrest if
necessary).

●

Slide the strap and secure it properly with

the anchorage of the backrest

›››

●

Firmly tighten the strap following the manu-

facturer's instructions.

Releasing the retaining strap

●

Loosen the strap following the manufactur-

er's instructions.

●

Push the lock and release it from the an-

choring support.

WARNING

An undue installation of the safety seat will
increase the risk of injury in the event of a
crash.

Tyre repair

TMS (Tyre Mobility System)

The Tyre Mobility System will reliably seal
punctures caused by the penetration of a for-
eign body of up to about

4 mm

in diameter.

Do not remove foreign objects, e.g. screws
or nails, from the tyre.

After inserting the sealant residue in the tyre,
you must again check the tyre pressure
about 10 minutes after starting the engine.

You should only use the tyre mobility set if the
vehicle is parked in a safe place, you are fa-
miliar with the procedure and you have the
necessary tyre mobility set! Otherwise, you
should seek professional assistance.

Do not use the tyre sealant in the following
cases:

●

If the wheel rim has been damaged.

●

In outside temperatures below -20°C

(-4°F).

●

In the event of cuts or perforations in the

tyre greater than 4 mm.

●

If you have been driving with very low pres-

sure or a completely flat tyre.

●

If the sealant bottle has passed its use by

date.

WARNING

Using the tyre mobility system can be dan-
gerous, especially when filling the tyre at
the roadside. Please observe the following
rules to minimise the risk of injury:

●

Stop the vehicle safely as soon as possi-

ble. Park it at a safe distance from sur-
rounding traffic to fill the tyre.

●

Ensure the ground on which you park is

flat and solid.

●

All passengers and particularly children

must keep a safe distance from the work
area.

●

Turn on the hazard warning lights to warn

other road users.

●

Use the tyre mobility system only if you

are familiar with the necessary procedures.
Otherwise, you should seek professional
assistance.

●

The tyre mobility set is intended for tem-

porary emergency use only until you can
reach the nearest specialised workshop.

●

Replace the repaired tyre with the tyre

mobility set as soon as possible.

●

The sealant is a health hazard and must

be cleaned immediately if it comes into
contact with the skin.

●

Always keep the tyre mobility set out of

the reach of small children.

Emergencies

●

Always stop the engine, apply the hand

brake and put it in gear when using a man-
ual gearbox, in order to reduce the risk of
involuntary movement of the vehicle.

WARNING

A tyre filled with sealant does not have the
same performance properties as a conven-
tional tyre.

●

Never drive faster than 80 km/h

(50 mph).

●

Avoid heavy acceleration, hard braking

and fast cornering.

●

Drive for only 10 minutes at a maximum

speed of 80 km/h (50 mph) and then check
the tyre.

For the sake of the environment

Dispose of used or expired sealant observ-
ing any legal requirements.

Note

A new bottle of sealant can be purchased
at SEAT dealerships.

Note

Take into account the separate instruction
manual of the tyre mobility system’s manu-
facturer.

Use only the wheel wrench belonging to the
car to loosen the wheel bolts.

Loosen the wheel bolts only about one turn
before raising the vehicle with the jack.

If the wheel bolt is very tight, carefully push
on the end of the wheel wrench with your
foot. Hold on to the vehicle for support and
take care not to slip during this operation.

Important information about wheel bolts

Factory-fitted rims and wheel bolts are spe-
cially matched during construction. There-
fore, if different rims are fitted, the correct
wheel bolts with the right length and heads
must be used. This ensures that wheels are
fitted securely and that the brake system
functions correctly.

In certain circumstances, you should not even
use wheel bolts from vehicles of the same
model.

In wheels with full hubcaps, the anti-theft
locking bolt must be threaded onto positions

›››

Fig. 34

, taking the tyre valve’s po-

sition as reference

. Otherwise it will not be

possible to mount the hubcap.

WARNING

If the wheel bolts are not properly tight-
ened, they could come loose while driving

Emergencies

and cause an accident, serious injury and
loss of vehicle control.

●

Use only wheel bolts which correspond

to the rim in question.

●

Never use different wheel bolts.

●

Wheel bolts and threads should be clean,

free of oil and grease, and it should be pos-
sible to screw them easily.

●

To loosen and tighten wheel bolts, only

use the wheel wrench that came with the
car from the factory.

●

The wheel bolts should only be loosened

slightly (about one turn) before raising the
vehicle with the jack. Risk of accident!

●

Never apply grease or oil to wheel bolts

or to the wheel hub threads. Even if the
bolts have been tightened to the prescri-
bed torque, they could come loose while
driving.

●

Never loosen the screwed joints of wheel

rims with bolted ring trims.

●

If wheel bolts are tightened below the

prescribed torque, the bolts and rims could
come loose while driving. If tightening tor-
que is too high, the wheel bolts or threads
can be damaged.

Raise the vehicle

Jack position points.

Fig. 36

Cross member: positioning the jack on

the vehicle.

●

Rest the jack (vehicles tools) on firm

ground. If necessary use a large, strong
board or similar support. If the surface is slip-
pery (for example tiles) place the jack on a
rubber mat or similar to prevent it from slip-
ping

›››

Self-help

●

Find the support point on the strut (sunken

area) closest to the wheel to be changed

›››

Fig. 35

●

Raise the jack with the crank handle until it

can be inserted just below the support point
of the vehicle.

●

Make sure that the base of the jack rests

firmly on the ground and that it is exactly be-
low the vertical support point

›››

Fig. 36

●

Centre the jack and continue to raise it us-

ing the crank handle until the claw grasps the
reinforcement located under the vehicle

›››

Fig. 36

●

Keep raising the jack until the wheel comes

slightly off the ground.

WARNING

The factory-supplied jack is only designed
for changing wheels on this model. On no
account attempt to use it for lifting heavier
vehicles or other loads. Risk of injury.

●

Make sure the jack remains stable. If the

surface is slippery or soft, the jack could
slip or sink, respectively, with the conse-
quent risk of causing injuries.

●

Lift the vehicle using only the jack sup-

plied from the factory. Other jacks, even
those approved for other SEAT models
could slip, with the consequent risk of in-
jury.

●

Place the jack only at the support points

provided on the strut and align it. Other-

wise, the jack could slip because it does
not have sufficient grip on the vehicle: risk
of injury!

●

You should never place a body limb such

as an arm or leg under a raised vehicle that
is solely supported by the jack.

●

If you have to work underneath the vehi-

cle, you must use suitable stands addition-
ally to support the vehicle, there is a risk of
accident!.

●

Never raise the vehicle if it is tilting to one

side or the engine is running.

●

Never start the engine when the vehicle is

raised. The vehicle may come loose from
the jack due to the engine vibrations.

CAUTION

The vehicle must not be raised on the
crossbar. Place the jack only at the support
points provided on the strut and align it.
Otherwise, the vehicle may be damaged.
