Wearing a correctly fastened seat belt can significantly change the situa-
tion. Properly worn seat belts hold the vehicle occupants in the correct sit-
ting positions and substantially reduce the kinetic energy in the event of an
accident. Seat belts also help to prevent uncontrolled movements that
could lead to severe injuries. In addition, properly worn seat belts reduce
the danger of being thrown from the car ⇒ Fig. 9.
Passengers wearing their seat belts correctly benefit greatly from the ability
of the belts to absorb kinetic energy. The front crumple zones and other
passive safety features (such as the airbag system) are also designed to ab-
sorb the kinetic energy generated in a collision. Taken together, all these
features reduce the energy released and decrease the risk of injury.
Our examples describe frontal collisions. Of course, properly worn seat belts
substantially reduce the risk of injury in all other types of accidents. This is
why it is so important to fasten seat belts before every trip, even when just
driving “around the corner”. Ensure that your passengers wear their seat
belts as well. Accident statistics have shown properly worn seat belts to be an effective
means of considerably reducing the risk of severe injury and improving the
chances of survival in a serious accident. Furthermore, properly worn seat
belts improve the protection provided by deployed 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 airbags, the seat belts must be fas-
tened and worn. The front airbags, for example, are only triggered in some
frontal accidents. The front airbags will not be triggered during minor frontal
collisions, minor side collisions, rear collisions, rolls or accidents in which
the airbag trigger threshold value in the control unit is not exceeded.
Therefore, you should always wear your seat belt and ensure that your pas-
sengers have fastened their seat belts properly before you drive off!

Fig. 14 Correct position-
ing of seat belts during
pregnancy
Seat belts offer their maximum protection in the event of an accident and
reduce the risk of sustaining severe or fatal injuries only when they are
properly positioned. Furthermore, if the webbing is correctly positioned, the
seat belt will hold the vehicle occupants in the optimum position to ensure the airbag provides the utmost protection. The seat belt must therefore al-
ways be worn and the webbing correctly positioned.
Incorrectly worn seat belts can cause severe or even fatal injuries
⇒ page 10, Adjusting the seat position.
Correct seat belt position
●
The shoulder part of the seat belt must lie on the centre of the shoulder,
never across the neck or the arm, under the arm or behind the shoulder.
● The lap part of the seat belt must lie across the pelvis, never across the
stomach.
● The seat belt must lie flat and fit comfortably. Pull the belt tight if neces-
sary to take up any slack.
In the case of pregnant women , the seat belt must lie evenly across the
chest and as low as possible over the pelvis, never across the stomach and
must be worn properly at all times during the pregnancy ⇒ Fig. 14.

Seat belt tensioners
Automatic belt retainer, belt tensioner, belt tension limiter
Seat belts are part of the vehicle safety concept ⇒ page 32 and consist of
the following important functions:
Automatic belt retainer
Every seat belt is equipped with an automatic belt retainer on the shoulder
belt. If the belt is pulled slowly or during normal driving, the system allows
for total freedom of movement on the shoulder belt. However, during sud-
den braking, during travel in mountains or bends and during acceleration,
the automatic belt retainer on the seat belt is locked is pulled quickly.
Belt tensioners
The seat belts on the front seats and the outer seats of the second row are
equipped with belt tensioners.
Sensors will trigger the belt tensioners during severe head-on, lateral and
rear collisions and retract and tighten the seat belts. If the seat belt is
loose, it is retracted to reduce the forwards movement of vehicle occupants
or movement in the direction of the collision. The belt tensioner works in
combination with the airbag system. The belt tensioner will not be triggered
in the event of the vehicle overturning if the side airbags are not deployed.
If the belt tensioner is triggered, a fine dust is produced. This is normal and
it is not an indication of fire in the vehicle. Belt tension limiter
The belt tension limiter reduces the force of the seat belt on the body in the
event of an accident.
Note
The relevant safety requirements must be observed when the vehicle or
components of the system are scrapped. These requirements are known to
specialised workshops ⇒ page 27. 
Service and disposal of belt tensioners
If you work on the belt tensioners or remove and install other parts of the
vehicle when performing other repair work, the seat belt may be damaged.
The consequence may be that, in the event of an accident, the belt tension-
ers function incorrectly or not at all.
So that the effectiveness of the belt tensioner is not reduced and that re-
moved parts do not cause any injuries or environmental pollution, regula-
tions must be observed. These requirements are known to specialised work-
shops.
WARNING
Improper handling and homemade repairs of seat belts, automatic belt
retainers and tension devices increase the risk of sustaining severe or fa-
tal injuries. The belt tensioner may fail to trigger or may trigger in the
wrong circumstances.
● Never attempt to repair, adjust or remove or install parts of the belt
tensioners or seat belts. Any work must be performed by a specialised
workshop only ⇒ page 260.
● Belt tensioners and automatic belt retainers cannot be repaired and
must be replaced. 

Brief introduction Introduction
Front airbags have been installed for both driver and passenger. The front
airbags can also protect the chest and head of driver and passenger if the
seats, seat belts head restraints and, for the driver, the steering wheel are
correctly adjusted and used. Airbags are considered as additional safety
equipment. An airbag cannot replace the seat belt, which must be worn at
all times, even in front seats where front airbags have been installed.

● Care and cleaning of the vehicle interior ⇒ page 252
● Accessories, parts replacement, repairs and modifications ⇒ page 260
● Notes for the user ⇒ page 258
WARNING
Never exclusively trust the airbag system as a means of protection.
● Even when triggered, airbag protection is only auxiliary.
WARNING (Continued)
● The airbags provide the best protection when the seat belts are prop-
erly fastened, thus reducing the risk of sustaining injuries ⇒ page 21,
Seat belts.
● Before each trip, every occupant must sit properly, correctly fasten
the seat belt belonging to his or her seat and keeping it fastened
throughout the trip. This rule is valid for all vehicle occupants.
WARNING
Vehicle occupants sitting in the front of the vehicle must never carry any
objects in the deployment space between them and the airbags, as this
increases the risk of sustaining injuries if the airbag is triggered. This
modifies the airbag deployment space or the objects may fly uncontrolla-
bly and hit your body.
● Never carry objects in your hand or on your lap while the vehicle is in
motion.
● Never transport objects on the front passenger seat. In the event of
sudden braking and manoeuvres, the objects may end up in the airbag
deployment space and fly uncontrollably around the vehicle interior if the
airbag is activated.
● Vehicle occupants of the front and outer rear seats must never carry
any other people, pets or objects in the deployment space between them
and the airbags. Make sure children and other passengers also respect
this recommendation. 

WARNING
The airbag system provides protection for one accident only. If they have
been deployed, they must be replaced.
● Ensure deployed airbags and the system components involved are im-
mediately replaced with new, SEAT-approved components for the vehicle.
● Have any repairs or modifications carried out at a specialised work-
shop. Specialised workshops have the necessary tools, diagnostics
equipment, repair information and qualified personnel.
● Never fit recycled or reused airbag components in your vehicle.
● Never modify the airbag system components.
WARNING
If the airbags are triggered, a fine dust is produced. This is normal and it
is not an indication of fire in the vehicle.
● This fine dust may irritate the skin and eyes and cause breathing dif-
ficulties, particularly in people suffering from or who have suffered from
asthma or other illnesses of the respiratory tract. To reduce breathing dif-
ficulties, get out of the vehicle and open and doors and windows to
breath in fresh air.
● Should you touch the dust, wash your hands and face using a mild
soap and water before you eat.
● Prevent the dust from affecting the eyes or open wounds.
● Rinse your eyes with water if you have dust in them.
WARNING
Solvents cause the surfaces of the airbag modules to become porous. If
an airbag is accidentally triggered, the detachment of plastic parts could
cause serious injury.
● Never clean the dash panel and the surfaces of the airbag modules
with cleaners containing solvents.

Airbag system Description and function of the airbag
The airbag can protect vehicle occupants in the event of an accidents, cush-
ioning the movement of the occupants in the direction of the collision in
frontal and side accidents.
Deployed airbags fill with a propellant gas. This causes the airbag covers to
break and the airbags to deploy extremely quickly in their entire deploy-
ment space within fractions of a second. When an occupant with the seat
belt properly fastened puts pressure on the inflated airbag, the propellant
gas escapes to absorb the force of the impact and slow the movement. This
reduces the risk of severe or fatal injuries. Airbag deployment does not
mean that other types of injury such as swelling, bruising, burns and skin
injuries can be ruled out.
Airbags do not protect the arms or the lower part of the body.
The most important factors for triggering the airbag are the type of accident,
the angle of impact, the vehicle speed and the characteristics of the object
the vehicle hits. Therefore, airbags are not triggered every time the vehicle
is visibly damaged.
The airbag system is designed to be triggered in collisions with a severe im-
pact. The front, curtain, side and knee airbags may be triggered under spe-
cial circumstances. The scope of any visible damage to the vehicle is not an
indication of airbag deployment. Airbags act in conjunction with three-point seat belts in the event of certain
accidents, when the vehicle deceleration rate is severe enough to trigger
the airbags. Airbags only deploy once and only under certain circumstan-
ces. Seat belts remain present to offer protection in situations where air-
bags are not triggered or where they have already deployed. For example,
when a vehicle hits another after an initial collision or is hit by another vehi-
cle.
The airbag system is an integral part of the car's passive safety system. The
airbag system can only work effectively when the vehicle occupants are
wearing their seat belts correctly and have adjusted the head restraints
properly
