Operation of side airbags
Inflated airbags can reduce the risk of head or chest injury in
many side impact collisions.In some side collisions , the side airbag is triggered on the impact side of the
vehicle ⇒page 39, fig. 22 .
In certain types of accident the front, curtain and side airbags may be trig-
gered together.
When the system is triggered, the airbag is filled with propellant gas.
The airbags deploy extremely rapidly, within thousandths of a second, to
provide additional protection in the event of an accident. A fine dust may
develop when the airbag deploys. This is normal and it is not an indication of
fire in the vehicle.
The fully deployed airbags cushion the movement of the occupants of the
front seats and the outer rear seats and help to reduce the risk of injury to the
upper body. The special design of the airbag allows the controlled escape of the propel-
lant gas when an occupant puts pressure on the bag. Thus, the head and
chest are surrounded and protected by the airbag.

40Safety notes on the operation of the side airbag system
If airbags are used correctly, they can considerably reduce the
risk of injury in side impact collisions.
WARNING
•If you do not wear a seat belt, if you lean forward, or are not seated
correctly while the vehicle is in motion, you are at a greater risk of injury if
the side airbag system is triggered in an accident.•In order for the side airbags to provide their maximum protection, the
prescribed sitting position must always be maintained with seat belts
fastened while travelling.•Occupants of the outer seats must never carry any objects or pets in the
deployment space between them and the airbags, or allow children or
other passengers to travel in this position. It is also important not to attach
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 us ed 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 exer ted upon the
backrest bolster because the system may be damaged. In this case, the
side airbags would not be triggered.•Under no circumstances should protective covers be fitted over seats
with side airbags unless the covers have been approved for use in your
vehicle. Because the airbag is triggered from the side of the backrest, the
use of non-approved seat covers would obstruct the side airbag, seriously
reducing the airbag’s effectiveness ⇒page 212, “Accessories, parts
replacement and modifications”.•Any damage to the original seat upholstery or around the seams of the
side airbag units must be repaired immediately by a specialised workshop.•The airbags provide protection for just one accident; replace them once
they have deployed.
•When children assume an incorrect sitting position, they expose them-
selves to an increased risk of injury in the event of an accident. This is
particularly the case if the child is travelling on the front passenger seat
and the airbag system is triggered in an accident; this could have critical
consequences including serious injury or death ⇒page 46, “Child safety”.•Any work on the side airbag system or removal and installation of the
airbag components 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 system in any way.•The side and head airbags are managed through sensors located in the
interior of the front doors. To ensure the correct functioning of the side and
head 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 made in a specialised workshop.WARNING (continued)

Curtain airbagsDescription of curtain airbags
The airbag system is not a substitute for the seat belts.The curtain airbags are located on both sides in the interior above the doors
⇒fig. 23 and are identified with the text “AIRBAG”.
In conjunction with the seat belts, the curtain airbag system gives the occu-
pants additional protection for the head and upper body in the event of a
severe side collision ⇒ page 42, “Safety notes on the operation of the
curtain airbag system”.
The airbag system is not a substitute for seat belts, but it is an integral part
of the vehicle’s overall passive safety system. Please bear in mind that the
airbag system can only work effectively when the occupants are wearing their
seat belts correctly and have adjusted the head restraints properly. Therefore,
it is most important to wear the seat belts at all times, not only because this is required by law in most countries, but also for your safety
⇒page 19,
“Brief introduction”.
The main parts of the curtain airbag system are:
•an electronic control and monitoring system (control unit)•the curtain airbags (airbags with ga s generator) for the driver, front
passenger and passengers on the rear seats,•a warning lamp
T on the instrument panel ⇒page 31
The airbag system operation is monitored electronically.
The curtain airbag system will not be triggered if:
•the ignition is switched off

If a fault has occurred in the airbag system, have the system checked imme-
diately by a specialised workshop. Otherwise there is a danger that during
a collision, the system may fail to trigger, or not trigger correctly.Operation of curtain airbags
Fully inflated airbags reduce the risk of head or chest injury in
a side collision.
During some side collisions the curtain airbag is triggered on the impact side
of the vehicle ⇒ fig. 24.
In certain types of accident the front, side and curtain airbags may be trig-
gered together.
When the system is triggered, the airbag is filled with propellant gas. In the
process, the curtain airbag covers the side windows and door pillars.
The airbags deploy extremely rapidly, within thousandths of a second, to
provide additional protection in the event of an accident. A fine dust may
develop when the airbag deploys. This is normal and it is not an indication of
fire in the vehicle.
The fully deployed airbags cushion the movement of the front occupants and
help to reduce the risk of injury to the upper body.
The special design of the airbag allows the controlled escape of the propel-
lant gas when an occupant puts pressure on the bag. Thus, the head and
chest are surrounded and protected by the airbag.Safety notes on the operation of the curtain airbag system
If you use airbags correctly, they can considerably reduce the
risk of injury in many kinds of accident.
WARNING
•In order for the side airbags to provide their maximum protection, the
prescribed sitting position must always be maintained with seat belts
fastened while travelling.•For safety reasons, the curtain airbag must be disconnected in those
vehicles fitted with a passenger compartment separation screen. See an
Authorised Service Centre to make this adjustment.

so that the curtain airbag can deploy without restriction 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
windows ⇒page 212, “Accessories, parts replacement and modifica-
tions”.•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 hangers.•The airbags provide protection for just one accident; replace them once

airbag off, an Authorised Service Centre must be consulted.•Never install a child seat facing backwards on the front passenger seat
unless the front passenger airbag has been disabled. Otherwise, there is a
risk of death. If under exceptional circumstances it is necessary to trans-
port a child in a rear-facing child seat on the front passenger seat, you must
always disable the front passenger airbag.•As soon as the child seat is no longer needed on the front passenger
seat, enable the front passenger airbag again.•Only deactivate the passenger airbag when the ignition is off, other-
wise a fault may occur in the airbag system, which could cause the airbag
to not deploy properly or not deploy at all.•When the passenger airbag is deactivated, if the warning lamp AIRBAG
OFF is not continuously lit up, there may be a fault in the airbag system:
−Have the airbag system inspected immediately by a specialised
workshop.
− Do not use a child seat on the front passenger seat! The front
passenger airbag could be triggered despite the fact that there is a fault
in the system and, as a result, a child could sustain serious or fatal inju-
ries.
− It is unpredictable whether the front passenger airbag will deploy in
the event of an accident. Warn all your passengers of this.
•When using the ignition key to activate/deactivate the front passenger
airbag, only the front passenger airbag will be activated/deactivated. The
side airbag and head airbag on the passenger side will remain active.WARNING (continued)

Child safety
46Child safetyBrief introductionIntroduction
Statistics show that children are generally safer on the rear
seat than on the front passenger seat.For safety reasons we recommend that children under 12 years of age travel
on the rear seats. Depending on their age, height and weight, children trav-
elling on the rear seat must use a child seat or a seat belt. For safety reasons,
the child seat should be installed in the centre of the rear seat or behind the
front passenger seat.
The physical laws involved and the forces acting in a collision apply also to
children. ⇒page 21, “Why wear seat belts?”.
But unlike adults, children do not have muscle and bone structures fully
developed. This means that children are subject to a greater risk of injury.
To reduce this risk, children must always use special child restraint systems
when travelling in the vehicle.
We recommend the use of child safety products from the SEAT Genuine Acces-
sories Programme, which includes systems for all ages made by “Peke”
2).
These systems have been especially designed and approved, complying with
the ECE-R44. regulation.
Follow the manufacturer’s instructions and observe any statutory require-
ments when installing and using child seats. Always read and note
⇒ page 47. We recommend you to include the manufacturer’s Child Seat instruction
manual together with the on-board documentation.

Safety notes on using child seats
Proper use of child seats substantially reduces the risk of
injury in an accident!As the driver, you are responsible for any children you transport in
your vehicle.
– Protect your children by properly using the appropriate child
seats ⇒page 48.
– Always ensure that the seat belt is properly positioned according to the instructions provided by the manufacturer of the child
seat.
– When travelling, do not allow children to distract you from traffic.
– Take breaks regularly during long trips. Take a break at least
every two hours.
WARNING
•Never install a child seat facing backwards on the front passenger seat
unless the front passenger airbag has been disabled. This could lead to a
risk of potentially fatal injuries to the child! However, if it is necessary, in
exceptional cases, to transport a child in the front passenger seat, the front
passenger airbag must always be disabled ⇒page 44, “Deactivating
airbags*”. If the passenger seat has a height adjustment option, move it to
the highest position.•For those vehicles that do not include a key lock switch to disconnect
the airbag, the vehicle must be taken to a Technical Service.•All passengers, especially children, must assume the proper sitting
position and be properly belted in while travelling.
•Never hold 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 vehicle 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 injuries
to themselves and to the other passengers.•If children assume an improper sitting position when the vehicle 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 accid ent ; as this could caus e s erious inj ur y or eve n deat h.•A suitable child seat can protect your child!•Never leave an unsupervised child alone on a child seat or in the
vehicle.•Depending on weather conditions, it may become extremely hot or cold
inside the vehicle. This can 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 twisted or jammed, or to rub on
any sharp edges.•Incorrectly worn seat belts can cause injuries even in a minor collision
or in sudden braking manoeuvres.•The seat belt provides maximum protection only when the seat belt is
properly positioned ⇒page 24, “Seat belts”.•Only one child may occupy a child seat ⇒page 48, “Child seats”.WARNING (continued)

Use only child seats that are officially approved and suitable
for the child.Child seats are subject to the regulation ECE-R 44. ECE-R stands for: Economic
Commission for Europe Regulation
The child seats are grouped into 5 categories:
Group 0 : children up to 10 kg
Group 0+ : children 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 approved under the ECE R44 standard
bear the test mark on the seat (the letter E in a circle with the test number
below it).
Group 0 and 0+ child seats
A suitable child seat and a correctly adjusted seat belt can
help you to protect your child.Group 0: For babies from about 9 months old and 10 kg in weight the most
suitable seats are those appearing in the illustration ⇒ fig. 27.
Group 0+: For babies from about 18 months old and 13 kg in weight the most
suitable seats are those appearing in the illustration.
Follow the manufacturer’s instructions and observe any statutory require-
ments when installing and using child seats.
We recommend you to include the manufacturer’s Child Seat instruction
manual together with the on-board documentation.
