Seat belts
Belt pretensioners* How the seat belt tensioner works During a frontal collision, the seat belts on
the front seats are retracted automatically.
The seat belts for the occupants in the front
seats are equipped with belt tensioners. Sen-
sors will trigger the belt pretensioners during
severe head-on, lateral and rear collisions
only if the seat belt is being worn. This re-
tracts and tightens the seat belts, reducing
the forward motion of the occupants.
The seat belt tensioner can be triggered only
once.
The belt tensioners will not be triggered in
the event of light frontal and side collisions,
if the vehicle overturns, or in situations
where no large forces act on the front, side or
rear of the vehicle.
Note
● If the seat 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
observed 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
tensioners
The belt tensioners are components of the
seat belts that are installed in the seats of
your vehicle. If you work on the belt tension-
ers or remove and install parts of the system
when performing other repair work, the seat
belt may be damaged. The consequence may
be that, in the event of an accident, the belt
tensioners function incorrectly or may not
function at all.
So that the effectiveness of the seat belt ten-
sioner is not reduced and that removed parts
do not cause any injuries or environmental
pollution, regulations, which are known to
the specialised workshops, must be ob-
served.
WARNING
● Improper use or repairs not carried out by
qualified mechanics increase the risk of se-
vere or fatal injuries. The belt tensioners may
fail to trigger or may trigger in the wrong cir-
cumstances.
● Never attempt to repair, adjust, remove or
install parts of the belt tensioners or seat
belts.
● The seat belt tensioner, seat belt and auto-
matic retractor cannot be repaired.
● Any work on the belt tensioners and seat
belts, including the removal and refitting of
system parts in conjunction with other repair work, must be performed by a specialised
workshop only.
●
The belt tensioners will only provide pro-
tection for one accident and must be changed
if they have been activated. 39Technical specifications

Airbag system
Brief introduction Why wear a seat belt and assume the
correct sitting position? For the inflating airbags to achieve the best
protection, the seat belt must always be worn
properly and the correct sitting position must
be assumed.
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 ef-
fectively when the vehicle occupants are
wearing their seat belts correctly and have
adjusted the head restraints properly. There-
fore, it is most important to properly wear the
seat belts at all times, not only because this
is required by law in most countries, but also
for your safety
›››
page 34, The reasons why
we should wear seat belts .
The airbag inflates in a matter of seconds, so
if you are not properly seated when the air-
bag is triggered, you may sustain fatal inju-
ries. Therefore, it is essential that all vehicle
occupants assume a correct sitting position
while travelling.
Sharp braking before an accident may cause
a passenger not wearing a seat belt to be
thrown forward into the area of the deploying airbag. In this case, the inflating airbag may
inflict critical or fatal injuries on the occu-
pant. This also applies to children.
Always maintain the greatest possible dis-
tance between yourself and the front airbag.
This way, the front airbags can completely
deploy when triggered, providing their maxi-
mum protection.
The most important factors that will trigger
an airbag are: the type of accident, the angle
of collision and the speed of the vehicle.
Whether or not the airbags are triggered de-
pends primarily on the vehicle deceleration
rate resulting from the collision and detected
by the control unit. If the vehicle deceleration
occurring during the collision and measured
by the control unit remains below the speci-
fied reference values, the front, side and/or
curtain airbags will not be triggered. Take in-
to account that the visible damage in a vehi-
cle involved in an accident, no matter how
serious, is not a determining factor for the
airbags to have been triggered.
WARNING
● Wearing the seat belt incorrectly or assum-
ing an incorrect sitting position can lead to
critical or fatal injuries.
● All vehicle occupants, including children,
who are not properly belted can sustain criti-
cal or fatal injuries if the airbag is triggered.
Children up to 12 years old should always travel on the rear seat. Never transport chil-
dren in the vehicle if they are not restrained
or the restraint system is not appropriate for
their age, size or weight.
●
If you are not wearing a seat belt, or if you
lean forward or to the side while travelling or
assume an incorrect sitting position, there is
a substantially increased risk of injury. This
increased risk of injury will be further in-
creased if you are struck by an inflating air-
bag.
● To reduce the risk of injury from an inflating
airbag, always wear the seat belt properly.
● Always adjust the front seats properly. Description of the airbag system
The airbag system mainly comprises (as per
vehicle equipment):
● an electronic control and monitoring sys-
tem (control unit)
● frontal airbags for driver and passenger,
● side airbags,
● curtain airbags,
● a control lamp  on the dash panel
››› page 42 .
● key
-operated switch for front passenger air-
bag,
● a control lamp for disabling/enabling the
front passenger airbag.
40

Airbag system
The airbag system operation is monitored
electronically. The airbag control lamp will il-
luminate for a few seconds every time the ig-
nition is switched on (self-diagnosis).
There is a fault in the system if the control
lamp 
:
● doe
s not light up when the ignition is
switched on ››› page 42
,
● turns off after 4 seconds after the ignition
is switched on
● turns off and then lights up again after the
ignition is switched on
● illuminates or flashes while the vehicle is
moving.
The airbag system is not triggered if:
● the ignition is switched off
● there is a minor frontal collision
● there is a minor side collision
● there is a rear-end collision
● the vehicle turns over. WARNING
● The seat belts and airbags can only provide
maximum protection if the occupants are
seated correctly ››› page 30, Proper sitting
position for occupants.
● If a fault has occurred in the airbag system,
have the system checked immediately by a
specialised workshop. Otherwise, during a frontal collision the system might not trigger
correctly or may fail to trigger at all.
Airbag activation
The airbags deploy extremely rapidly, within
thousandths of a second, to provide addi-
tional protection in the event of an accident.
A fine dust may develop when the airbag de-
ploys. This is normal and it is not an indica-
tion of fire in the vehicle.
The airbag system is only ready to function
when the ignition is on.
In special accidents instances, several air-
bags may activate at the same time.
In the event of minor head-on and side colli-
sions, rear-end collisions, overturning or roll-
over of the vehicle, airbags
do not activate.
Activation factors
The conditions that lead to the airbag system
activating in each situation cannot be gener-
alised. Some factors play an important role,
such as the properties of the object the vehi-
cle hits (hard/soft), angle of impact, vehicle
speed, etc.
Deceleration trajectory is key for airbag acti-
vation. The control unit analyses the collision trajec-
tory and activates the respective restraint
system.
If the deceleration rate is below the prede-
fined reference value in the control unit the
airbags will not be triggered, even though
the accident may cause extensive damage to
the car.
The following airbags are triggered in
serious head-on collisions
● Driver airbag.
● Front passenger front airbag
The following airbags are triggered in
serious side-on collisions
● Front side airbag on the side of the acci-
dent.
● Rear side airbag on the side of the acci-
dent.
● Curtain (head) airbag on the side of the ac-
cident.
In an accident with airbag activation:
● the interior lights switch on (if the interior
light switch is in the courtesy light position);
● the hazard warning lights switch on;
● all doors are unlocked;
● the fuel supply to the engine is cut.

Control lamp for airbag and seat belt
tensioner The control lamp monitors all airbags and
seat belt tensioners in the vehicle, including
control units and wiring connections.
Monitoring of airbag and belt tensioner
system
Both the airbag and belt tensioner systems
operation is constantly monitored electroni-
cally. The control lamp
 will light up for a
few seconds every time the ignition is switch-
ed on (self-diagnosis).
The system must be checked when the
control lamp  :
● does not light up when the ignition is
switched on,
● turns off after 4 seconds after the ignition
is switched on
● turns off and then lights up again after the
ignition is switched on
● illuminates or flashes while the vehicle is
moving.
In the event of a malfunction, the warning
lamp remains on continuously. Have the air-
bag system inspected immediately by a spe-
cialised workshop.
If any of the airbags are disabled by a Techni-
cal Service, the warning lamp flashes for sev- eral more seconds after verification and will
turn off if there is no fault. WARNING
● If there is a malfunction, the airbag and
belt tensioner system cannot properly per-
form its protective function.
● If a malfunction occurs, have the system
checked immediately by a specialised work-
shop. Otherwise, in the event of an accident,
the airbag system and belt tensioners may
not be triggered, or may not be triggered cor-

The airbag covers fold out of the steering
wheel and dashboard respectively when the
driver and front passenger airbags are trig-
gered ››› Fig. 57
. The airbag covers remain connected to the steering wheel or the dash
panel.
In conjunction with the seat belts, the front
airbag system gives the driver and the front
passenger additional protection for the head
and chest in the event of a severe frontal col-
lision.
The special design of the airbag allows the
controlled escape of the propellant gas when
an occupant puts pressure on the bag. Thus,
the head and chest are surrounded and pro-
tected by the airbag. After the collision, the
airbag deflates sufficiently to allow visibility.
WARNING
● The seat belts and airbags can only provide
maximum protection if the occupants are
seated correctly ››› page 30, Proper sitting
position for occupants.
● The deployment space between the front
passengers and the airbags must not in any
case be occupied by other passenger, pets
and objects.
● The airbags provide protection for just one
accident; replace them once they have de-
ployed.
● It is also important not to attach any ob-
jects such as cup holders or telephone
mountings to the surfaces covering the air-
bag units.
● Do not attempt to modify components of
the airbag system in any way. Side airbags*

The essentials

Safety
In conjunction with the seat belts, the side
airbag system gives the front seat occupants
additional protection for the upper body in
the event of a severe side collision.
In a side collision, the side airbags reduce
the risk of injury to passengers on the front
seats to the areas of the body facing the im-
pact. In addition to the normal protection
they offer, the seat belts on the front seats al-
so hold the passengers' bodies in place in
the event of a side collision so that the side
airbags can provide maximum protection. 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 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 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 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 seams of the side airbag units
must be repaired immediately by a special-
ised workshop.
● The airbags provide protection for just one
accident; replace them once they have de-
ployed.
● Any work on the side airbag system or re-
moval 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 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 operation of
the side and curtain (head) airbags neither the doors nor the door panels should be
modified in any way (e.g. fitting loudspeak-
ers). If the front door is damaged, the airbag
system may not work correctly. All work car-
ried out on the front door must be done in a
specialised workshop.
●
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 removed 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 covered if additional loudspeakers or other
equipment are fitted inside the door panels.
● Any work carried out to the doors should be
made in an authorised specialised workshop. 44

In the event of a side collision the curtain air-
bag is triggered on the impact side of the ve-
hicle.
In side collisions, the head-protection air-
bags reduce the risk of injury to passengers
in the front and rear side seats facing the im-
pact. WARNING
The airbag is deployed at high speed in frac-
tions of a second.
● Do not obstruct the head-protection airbag
deployment areas.
● Never secure objects over the curtain air-
bag cover or in its deployment area.
● Occupants of the front seats and rear side
seats must never carry any other people, ani-
mals or objects in the deployment space be-
tween them and the airbags. Make sure that
all the vehicle occupants, including children,
observe this.
● The clothes hangers are intended only for
light articles of clothing. Do not leave any
heavy or sharp-edged objects in the pockets.
● Do not mount accessories on the doors.
● Use only sun blinds which have been ex-
pressly approved for use in your vehicle.
● Do not turn the sun blinds towards the win-
dows if there are objects, e.g. pens or garage
remote controls, secured to them. Deactivating airbags

Safety
If you fit a rear-facing child seat to the front
passenger seat, the front passenger front air-
bag must be de-activated.
When the front passenger airbag is deactiva-
ted , this means that only the front passenger
fr ont
airbag is deactivated. All the other air-
bags in the vehicle remain activated.
Activating the front passenger front airbag
– Switch the ignition off.
– Open the glove compartment on the front
passenger side.
– Insert the key into the slot of the switch for
deactivating the front passenger airbag
››› Fig. 61. About 3/4 of the key should en-
ter

, as far as it will go.
– Then turn the key gently to the  position.
Do not force it if you feel resistance, and
make sure you have inserted the key fully.
– When the ignition is switched on, check
whether the control lamp   
  on the dash panel does ››› Fig. 62 not
light

up ››› .
WARNING
● It is the driver's responsibility to ensure
that the key operated switch is set to the cor-
rect position.
● You should deactivate the front passenger
front airbag only if you have to use a rear-fac- ing child seat in exceptional cases
››› page 46, Transporting children safety.
● Never install a child seat facing backwards
on the front passenger seat unless the front
passenger front airbag has been disabled.
Otherwise, there is a risk of death.
● As soon as the child seat is no longer nee-
ded on the front passenger seat, enable the
front passenger front airbag again.
● Only deactivate the front passenger front
airbag when the ignition is off, otherwise a
fault may occur in the airbag system, which
could cause the airbag to not deploy properly
or not deploy at all in case of an accident.
● Never leave the key in the airbag disabling
switch as it could get damaged or enable or
disable the airbag during driving.
● When the passenger airbag is deactivated,
if the control lamp      is not
continuously lit up when the front passenger
airbag is disabled, there may be a fault in the
airbag system:
–Have the airbag system inspected imme-
diately by a specialised workshop.
– Do not use a child seat on the front pas-
senger seat! The front passenger front
airbag could be triggered in the event of
an accident, even if there is a fault in the
system and, as a result, a child could sus-
tain serious or fatal injuries.
– It is unpredictable whether the front pas-
senger airbag will deploy in the event of
an accident. Warn all your passengers of
this. Transporting children safety
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 36 . But unlike adults, children do not
h av

e 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.

Transporting children safety
Follow the manufacturer's instructions and
observe any statutory requirements when in-
stalling and using child seats. Always read
and note ››› page 47 .
W e r
ecommend you always carry the manu-
facturer's Child Seat Instruction Manual to-
gether with the on-board documentation.
Important information on the front
passenger airbag Fig. 63
Passenger's side sun visor: airbag
sticker. Fig. 64
On the rear frame of the passenger
side door: airbag sticker. A sticker with important information about
the passenger airbag is located on the pas-
senger's sun visor and/or on the passenger
side door frame. Read and always observe
the safety information included in the follow-
ing chapters:
● Safety distance with respect to the passen-
ger airbag ››› page 40 .
● Ob

jects between the passenger and the
passenger side airbag ››› in Front airbags
on page 43 .
The p a

ssenger 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 45.
When transporting children, use a child seat
appropriate to the age and size of each child. 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 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 45, Front
passenger airbag deactivation*. If the front
passenger seat has a height adjustment op-
tion, move it to the highest position.
● For those vehicles that do not include a key
lock switch 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. » 47

Safety
●
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 in-
juries to themselves and to the other vehicle
occupants.
● If children assume an improper sitting posi-
tion 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 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 34. ●
Only one child may occupy a child seat
››› page 48, Child seats.
● When a c hi
ld seat is mounted in the rear
seats, the door child-proof lock should be ac-
tivated ››› page 82. Child seats
Categorisation of child seats into
groups Only use child seats that are officially ap-
proved 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)
Gr oup 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) Group 3: From 22 to 36 kg (over around 7
years old)
Child seats that have been tested and ap-
proved under the ECE R44 standard bear the
test mark on the seat (the letter E in a circle
with the test number below it).
Follow the manufacturer's instructions and
