2015 Seat Altea airbag off

Safety
– Instruct your passengers to fasten their
seat belts properly before driving off.
– Protect children by using a child seat ac-
cording to the child's height and weight.
The control lamp  on the instrument panel
lights up 1)
if the driver's seat belt is not fas-
tened when the ignition is switched on.
If, when starting to drive, the speed surpass-
es 25 km/h (15 mph) approx. and no seat
belt is worn or it is unfastened during the
drive, a warning sound will be heard for a few
seconds. The warning light will also flash .
The  lamp goes out when the seat belt is
fastened with the ignition switched on. Seat belt protection Fig. 7
Drivers with properly worn seat belts
will not be thrown forward in the event of sud-
den braking Properly worn seat belts hold the occupants
in the proper position. They also help prevent
uncontrolled movements that may result in
serious injury and reduce the risk of being
thrown out of the vehicle in case of an acci-
dent.
Vehicle occupants wearing their seat belts
correctly benefit greatly from the ability of the
belts to absorb kinetic energy. The front part
of your vehicle and other passive safety fea-
tures (such as the airbag system) are also de-
signed to absorb the kinetic energy released
in a collision. Taken together, all these fea-
tures reduce the releasing kinetic energy and
consequently, the risk of injury. This is why itis so important to fasten seat belts before ev-
ery trip, even when "just driving around the
corner".
Ensure that your passengers wear their seat
belts as well. Accident statistics have shown
that wearing seat belts is an effective means
of substantially reducing the risk of serious
injury and improving the chances of survival
when involved in an accident. Furthermore,
properly worn seat belts improve the protec-
tion provided by airbags in the event of an
accident. For this reason, wearing a seat belt
is required by law in most countries.
Although your vehicle is equipped with air-
bags, the seat belts must be fastened and
worn. The front airbags, for example, are only
triggered in some cases of head-on collision.
The front airbags will not be triggered during
minor frontal or side collisions, rear-end colli-
sions, rollovers or accidents in which the air-
bag trigger threshold value in the control unit
is not exceeded.
Therefore, you should always wear your seat
belt and ensure that all vehicle occupants
have fastened their seat belts properly before
you drive off!

Safety
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
››› page 11.
● Alw
ays adjust the front seats properly. Description of 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 (head) airbags,
● a control lamp  on the dash panel
››› page 19 .
● a k ey

-operated switch for front passenger
airbag, ●
a control lamp for disabling/enabling the
front passenger airbag.
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  :
● does

not light up when the ignition is
switched on ››› page 19,
● turn

s 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 6, Proper sitting po-
sition 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 cases of an accident, 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. There are some factors that play an
important role, such as the properties of the
object the vehicle hits (hard/soft), angle of
impact, vehicle speed, etc.
The deceleration trajectory is key for airbag
activation.
18

Airbag system
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 airbag on the side of the accident.
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. Each time the ignition is switched on,
the control lamp
 illuminates for several
seconds (self-diagnosis) and the instrument
panel display* shows AIRBAG/TENSIONER
.
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. In addition,
depending on the malfunction, a fault mes-
sage appears on the instrument panel dis-
play for approximately 10 seconds and a
short audible warning is given. In this event, you should have a specialised workshop
check the system immediately.
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-
rectly. 19Technical specifications

Airbag system
Side airbags* Fig. 15
Side airbag in driver seat. Fig. 16
Inflated side airbag on left side of ve-
hicle. The side airbags are located in the backrest
cushions of the driver seat
››› Fig. 15 and the
fr ont
passenger seat and the rear side air-
bags are mounted in the rear wheel housing.
The locations are identified by the text “AIR-
BAG” in the upper region of the backrests
and in the rear wheel housing lining. 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 their normal function of
protecting the occupants in a collision, the
seat belts also hold the passengers in the
front seats and the outer rear seats in a posi-
tion where these airbags can provide maxi-
mum 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 is trig-
gered from the side of the backrest, the use
of non-approved seat covers would obstruct
the side airbag, seriously reducing the air-
bag's effectiveness ››› page 147.
● 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

Airbag system
●
Any work on the head-protection airbag
system 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 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 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

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 24, 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 deactiva-
tion switch as it could get damaged or acti-
vate or deactivate the airbag during driving. ●
When the front passenger front airbag is
deactivated, if the control lamp AIRBAG OFF
is not continuously lit up, 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.
● When using the ignition key to activate/de-
activate the front passenger front airbag, on-
ly the front passenger airbag will be activa-
ted/deactivated. The side airbag and head
airbag on the passenger side will remain ac-
tive. 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 the rear seat
must use a child seat or a seat belt. For safety
reasons, 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 13 . 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.

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.
● Only one child may occupy a child seat
››› page 26, Child seats. ●
When a child seat is mounted in the rear
seats, the door child-proof lock should be ac-
tivated ››› page 66. Child seats
Categorisation of child seats into
groups Use only 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 around 4
years old)
Group 2
: From 15 to 25 kg (up to around 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
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.
WARNING
Read and always observe information and
warnings concerning the use of child seats
››› page 25. Ways to secure a child seat
You can secure a child seat to the rear seat or
front passenger seat in the following ways:
● Child seats in groups 0 to 3 can be secured
w ith a se

at belt.
● Child seats for groups 0, 0+ and 1
can be
fastened without seatbelts, using the “ISO-
FIX” and Top Tether* system, using the “ISO-
FIX” and Top Tether* securing rings

Automatic locking system for
involuntary unlocking* It is an anti-theft system and prevents the un-
intentional unlocking of the vehicle.
If the vehicle is unlocked and none of the
doors (including the boot) are opened within
30 seconds, it re-locks automatically. This
function prevents the vehicle from remaining
unlocked if the unlock button is pressed by
mistake.
Emergency unlocking system If the airbags are triggered during an acci-
dent, the vehicle is unlocked, except for the
luggage compartment. It is possible to lock
the vehicle from inside with the central lock-
