Ensuring you are correctly and safely seated
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. 

Driving tips Introduction
Always transport heavy loads in the luggage compartment and place the
seat backs in a vertical position. Never overload the vehicle. Both the carry-
ing capacity as well as the distribution of the load in the vehicle have ef-
fects on the driving behaviour and braking ability ⇒ 
.
Additional information and warnings:
● Rear lid ⇒ page 40
● To lower the front passenger seat backrest ⇒ page 55
● Light ⇒ page 84
● Luggage compartment ⇒ page 100
● Roof carrier ⇒ page 104
● Wheels and tyres ⇒ page 210
WARNING
Unsecured or incorrectly secured objects can cause serious injury in case
of a sudden manoeuvring or breaking or in case of an accident. This is es-
pecially true when objects are struck by a detonating airbag and fired
through the vehicle interior. To reduce the risks, please note the follow-
ing:
● Secure all objects in the vehicle. Always keep equipment and heavy
objects in the luggage compartment.
WARNING (Continued)
● Always secure objects with suitable rope or slings so that they cannot
enter the deployment areas around the frontal or side airbags in case of
sudden braking or an accident.
● Always ensure that objects inside the vehicle cannot move into the
deployment area of the bags while driving.
● While driving, always keep object compartments closed.
● Remove all objects from the front passenger seat when this is fol-
lowed down. When the seat backrest is folded down, it presses on small
and light objects and these are detected by the weight sensor on the
seat; this sends false information to the airbag control unit.
● While the backrest of the front passenger seat is folded, the frontal
airbag must remain disconnected and the PASSENGER AIRBAG OFF 
light on.
● Objects secured in the vehicle should never be placed in such a way
as to make passengers sit in an incorrect position.
● If secured objects occupy a seat then this should not be occupied or
used by anybody.
WARNING
The driving behaviour and braking ability change when transporting
heavy and large objects.
● Adjust your speed and driving style to visibility, road, traffic and
weather conditions.
● Accelerate gently and carefully.
● Avoid sudden braking and manoeuvres.
● Brake early.

Parking distance warning system*
Introduction
The parking distance warning system assists the driver when parking. If the
rear of the vehicle is approaching an obstacle, an intermittent audible warn-
ing is emitted. The shorter the distance, the shorter the intervals between
tones. If the vehicle is too close to the obstacle, the audible warning be-
comes constant.
If you continue to approach an obstacle when the sound is continuous, this
means the system can no longer measure the distance.
Sensors situated on the rear bumper transmit and receive ultrasound. Using
the ultrasound signal (transmission, reflection from the obstacles and re-
ception), this system continuously calculates the distance between the
bumper and the obstacle.
Additional information and warnings:
● Exterior detail ⇒ page 6
● Accessories, parts replacement, repairs and modifications ⇒ page 222
WARNING
The parking distance warning system cannot replace the driver's assess-
ment of the situation.
● The sensors have blind spots in which obstacles and people are not
registered.
● Always observe the area around the vehicle, as the sensors do not al-
ways detect small children, animals or objects.
WARNING (Continued)
● The surface of certain objects and some clothing do not reflect the ul-
trasound signals from the parking distance system. The system cannot
detect or incorrectly detects these objects and people wearing these
types of clothes.
● External sound sources can affect the parking distance aid signals. In
this case, under certain circumstances, people and objects will not be de-
tected.
CAUTION
● The sensors may not always be able to detect objects such as trailer
draw bars, thin rails, fences, posts, trees and open boots, etc. This could re-
sult in damage to your vehicle.
● Although the parking distance warning system detects and warns of the
presence of an obstacle, the obstacle could disappear from the angle of
measurement of the sensors if it is too high or low and the system would no
longer indicate it. Therefore, it will not warn you of these objects. Ignoring
the warnings of the parking distance warning system could cause consider-
able damage to the vehicle.
● The bumper sensors may become damaged or misaligned, for example,
when parking.
● To ensure that the system works properly, the bumper sensors must be
kept clean, free of ice and snow and uncovered.
● When cleaning the sensors with high-pressure or steam cleaning equip-
ment, spray the sensors briefly at a distance of no less than 10 cm.
● Different sources of noise can produce errors in the parking distance
warning system, i.e. parking distance warning systems from other vehicles,
inductive loops or construction works machines.
● Retrofitting of components to the vehicle, such as a bicycle carrier, may
interfere with the function of the parking distance warning system. 

Parking distance warning system
Fig. 93 Parking distance
warning system sensors
on the rear bumper
The 3 sensors of the parking distance warning system are situated on the
rear bumper ⇒ Fig. 93. Switching the parking distance warning system on and off
● Switching on: With the ignition switched on, select reverse gear. A short
audible warning confirms that the parking distance warning system is
switched on and functioning.
● Switching off: release reverse gear.
Things to note on the parking distance warning system
● The parking distance warning system sometimes registers water on the
sensors as an obstacle.
● If the distance does not change, the warning signal will sound less loud-
ly after a few seconds. If the continuous signal sounds, the volume will re-
main constant. ●
When the vehicle moves away from the obstacle, the beeping sound au-
tomatically switches off. On approaching the obstacle again, the beeping
sound will automatically switch back on.
● Your SEAT dealership can adjust the volume of the warning signals.
Note
A fault in the parking distance warning system is indicated through a brief
audible warning that is constant for about 3 seconds when switching on for
the first time. Check the parking distance warning system at a Specialised
workshop as soon as possible. 

Driver assistance systems
Safety Assist* (City Safety Assist function) Introduction
The City Safety Assist function covers driving situations at a distance of
about 10 metres in front of the vehicle, in a speed range of approximately
5-30 km/h (3-19 mph).
When the system detects a possible collision with a vehicle in front, the ve-
hicle prepares for a possible emergency braking ⇒ 
.
If the driver does not react to an imminent collision, the system can auto-
matically brake the vehicle in order to reduce speed faced with a possible
collision. The system can help to reduce the consequences of an accident.
If the City Safety Assist function determines that the driver braked insuffi-
ciently faced with an imminent collision, the system can increase the brake
force in order to reduce speed. The system can help to reduce the conse-
quences of an accident.
Additional information and warnings:
● Exterior detail ⇒ page 6
● Centre console, lower section ⇒ page 12
● Instrument panel ⇒ page 15
● Accessories, parts replacement, repairs and modifications ⇒ page 222
WARNING
The intelligent technology in the City Safety Assist system cannot change
the limits imposed by the laws of physics and by the system itself. The
increased comfort offered by the City Safety Assist system should never
prompt you to take risks. The driver always assumes the responsibility of
braking in time.
● The City Safety Assist function can not individually prevent accidents,
nor serious injury.
● The City Safety Assist system may carry out unwanted brake interven-
tions in complex driving situations i.e. when a vehicle crosses at a short
distance.
WARNING
Including the role of the City Safety Assist system in driving conduct may
cause accidents and serious injury. The system is not a replacement for
driver awareness.
● Always adapt your speed and the distance to the vehicles ahead in
line with visibility, weather conditions, the condition of the road and the
traffic situation.
● The City Safety Assist function does not react to people, animals or
vehicles that cross or move in the opposite direction in the same lane.
● If after switching on the City Safety Assist function the vehicle begins
to move, slow the vehicle with the foot brake.
CAUTION
If you suspect that the laser sensor of the City Safety Assist function is dam-
aged, switch off the City Safety Assist function. This will avoid additional
damage.
● Any reparation of the laser sensor requires specialist knowledge. SEAT
recommends visiting a Technical Service. 
