Ensuring you are correctly and safely seated
Fastening the seat belt
Fasten your seat belt before each trip.
● Correctly adjust the front seat ⇒ page 48.
● Engage the seat backrest in the upright position and correctly adjust the
hear restraint ⇒ 
.
● Pull the latch plate and place the belt webbing evenly across your chest
and lap. Do not twist the seat belt when doing so ⇒ 
.
● Engage the latch plate in the buckle of the corresponding seat ⇒ Fig. 42.
● Pull the belt to ensure that the latch plate is securely engaged in the
buckle.
Unfastening the seat belt
The seat belt must not be unfastened until the vehicle has come to a stand-
still ⇒ 
. ●
Press the red button on the buckle ⇒ Fig. 43. The latch plate is released
from the buckle.
● Guide the belt back by hand so that it rolls up easily and the trim will not
be damaged.
WARNING
An incorrectly worn seat belt web can cause severe or fatal injuries in the
event of an accident.
● The seat belt cannot offer its full protection unless the backrests are
in an upright position and the seat belt is worn correctly, according to
your size.
● Unbuckling your seat belt while the vehicle is in motion can cause se-
vere or fatal injuries in the event of an accident or sudden braking.

Fig. 45 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 occupants in the optimum position to ensure the air-
bag provides the utmost protection. The seat belt must therefore always be
worn and the webbing correctly positioned.
Incorrectly worn seat belts can cause severe or even fatal injuries
⇒  page 48, 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 seat belt tight if
necessary 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.
Pregnant women must wear the seat belt properly at all times during the
pregnancy ⇒ Fig. 45. Adapting the position of the seat belt webbing to your size
The seat belt can be adapted using the following equipment:
●
Front seat height adjustment.
WARNING
An incorrectly worn seat belt web can cause severe injuries in the event
of an accident or sudden braking or manoeuvre.
● The seat belt cannot provide optimum protection if it is not correctly
worn and the backrest is not tilted slightly backwards.
● The seat belt itself or a loose seat belt can cause severe injuries if the
belt moves from hard areas of the body to soft areas (e.g. the stomach).
● The shoulder part of the seat belt must lie on the centre of the shoul-
der, never across the neck or the arm.
● The seat belt must lie flat and fit comfortably on the torso.
● 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 on the pelvis.
Pull the seat belt tight if necessary to take up any slack.
● Pregnant women must wear the lap part of the seat belt as low as
possible over the pelvis and always lie it flat, “surrounding” the stom-
ach.
● Do not twist the seat belt while it is fastened.
● Never pull the seat belt away from your body using your hand.
● Do not lie the seat belt across rigid or fragile objects, e.g. glasses,
pens or keys.
● Never use seat belt clips, retaining rings or similar instruments to al-
ter the position of the belt webbing. 

Note
If your physical constitution prevents you from maintaining the correct posi-
tion of the belt webbing, contact a Specialised workshop for help with any
special devices to ensure the optimum protection of the seat belt and air-
bag. SEAT recommends visiting a Technical Service. 
Automatic belt retainer, belt tension device, belt tension
limiter
Seat belts are part of the vehicle safety concept ⇒ page 67 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 tension devices
The seat belts for the front occupants are equipped with belt tensioners.
Sensors will trigger the belt tension devices 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 occupants or
movement in the direction of the collision. The belt tension device works in
combination with the airbag system. The belt tension device will not be trig-
gered in the event of the vehicle overturning if the side airbags are not de-
ployed.
If the belt tension device 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 65. 
Service and disposal of belt tension devices
If you work on the belt tension devices or remove and install other parts of
the vehicle when performing other repair work, the seat belt may be dam-
aged. The consequence may be that, in the event of an accident, the belt
tension devices function incorrectly or not at all.
Observe regulations so that the effectiveness of the belt tension device is
not reduced and that removed parts do not cause any injuries or environ-
mental pollution. These requirements are known to qualified dealerships.
WARNING
Improper handling and home-made repairs of seat belts, automatic belt
retainers and tension devices increase the risk of sustaining severe or fa-
tal injuries. The belt tension device may fail to trigger or may trigger in
the wrong circumstances.
● Never attempt to repair, adjust or remove or install parts of the belt
tension devices or seat belts. Any work must be performed by a special-
ised workshop only ⇒ page 222.
● Do not repair belt tension devices and automatic belt retainers. Re-
place them. 

Airbag system 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 safety belt, which must be worn at
all times, even in front seats where front airbags have been installed.
Additional information and warnings:
● Driving tips ⇒ page 25
● Correct sitting position ⇒ page 48
● Seat belts ⇒ page 57
● Child seats (accessories) ⇒ page 76
● Care and cleaning of the vehicle interior ⇒ page 205
● Accessories, parts replacement, repairs and modifications ⇒ page 222
● Notes for the user ⇒ page 233
WARNING
Never exclusively trust the airbag system as a means of protection.
● Even when triggered, airbag protection is only auxiliary.
● The airbags provide the best protection when the seat belts are prop-
erly fastened, thus reducing the risk of sustaining injuries ⇒ page 57,
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 occupants.
WARNING
Occupants sitting in the front of the vehicle must never carry any objects
in the deployment space between them and the airbags, as this increa-
ses the risk of sustaining injuries if the airbag is triggered. This modifies
the airbag deployment space or the objects may fly uncontrollably 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 interior if the airbag
is activated.
● Occupants of the front and rear seats must never carry any other peo-
ple, pets or objects in the deployment space between them and the air-
bags. Make sure children and other passengers also respect this recom-
mendation.
WARNING
The airbag system provides protection for one accident only. If they have
been deployed, replace them.
● 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.

WARNING
In the event of a fault in the airbag system, the airbag may not trigger
correctly, may fail to trigger or may even trigger unexpectedly, leading to
severe or fatal injuries.
● Have the airbag system checked immediately by a Specialised work-
shop.
● Never mount a child seat in the front passenger seat or remove the
mounted child seat! The front passenger airbag may deploy during an ac-
cident in spite of the fault.
CAUTION
Always pay attention to any lit lamps and to the corresponding descriptions
and instructions to avoid damage to the vehicle. 
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 and skin injuries
can be ruled out. Upon deployment of the airbag, friction can cause the
generation of heat.
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 activation of the airbag system depends on the magnitude of the decel-
eration of the vehicle caused by a collision, which registers through an elec-
tronic control unit. If the deceleration magnitude value is below the refer-
ence value programmed in the control unit, the airbags will not deploy de-
spite serious damage being caused to the vehicle by the accident. Damage
suffered by the vehicle, reparation costs or absence of damage suffered
from the accident are not indications of whether an airbag should have
been deployed. Due to the varying nature of collision situations, it is impos-
sible to define a speed range of the vehicle and reference values. For this
reason, it is not possible to cover all types of collisions and collision angles
resulting in the deployment of the airbag. Factors necessary for the airbag
to be deployed can be, the characteristics of the object (hard or soft)
against which the vehicle collides, the collision angle and the vehicle
speed.
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 vehicle's passive safety system.
The airbag system can only work effectively when the occupants are wear-
ing their seat belts correctly and have adjusted the head restraints properly
