Airbag system
30Airbag systemBrief introductionWhy wear a seat belt and assume the correct sitting position?
For the inflating airbags to achieve the best protection, the
sea t b el t m u st al w ay s b e w o rn p ro p e rly a nd t h e co rrec t s i tt i n g
position must be assumed.For your own safety and the safety of the passengers, please ensure
the following before you drive:
– Always wear the seat belt properly ⇒page 19.
– Adjust the driver seat and the steering wheel correctly ⇒page 10.
– Adjust the front passenger seat correctly ⇒page 11.
– Adjust the head restraint seat correctly ⇒page 13.
– Use the correct child restraint system to protect children in your vehicle ⇒page 46.The airbag deploys in fractions of a second and with a high velocity. If you
have assumed an incorrect seating po sition at that moment, you could
sustain critical injuries. Therefore, it is essential that all occupants maintain
a correct sitting position while travelling.
Braking heavily the moment before an accident may cause an occupant not
wearing a seat belt to be thrown forwar d into the area of the deploying airbag. In this case, the inflating airbag may infl
ict critical or fatal injuries upon the
occupant. This applies particularly to children.
Always maintain the greatest possible distance between yourself and the
front airbag. This way, the front airbags can completely deploy when trig-
gered, providing their maximum protection.
The most important factors for triggering the airbag are the type of accident,
the angle of impact and the vehicle speed.
Whether the airbags are triggered depends primarily on the vehicle deceler-
ation rate resulting from the collision an d detected by the control unit. If the
vehicle deceleration occurring duri ng the collision and measured by the
control unit remains below the specifie d reference values, the front, side
and/or curtain airbag will not be triggered. Take into account that the visible
damage in a vehicle following an accident, for whatever reason, are not an
indication as to why the airbags were triggered.
WARNING
•
Wearing the seat belt incorrectly or assuming an incorrect sitting posi-
tion can lead to critical or fatal injuries.
•
All occupants, including children, who are not properly belted can
sustain critical or fatal injuries if the airbag is triggered. You should always
transport all children up to 12 years of age on the rear seat. Never transport
children 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 or
assume an incorrect sitting position, the risk of injury is increased
substantially. This increased risk of injury will be further increased if you
are struck by an inflating airbag.
•
To reduce the risk of injury from an inflating airbag, always wear the
seat belt properly ⇒ page 19.

Seats and stowage
126Seats and stowageThe importance of correct seat adjustmentProper seat adjustment optimi ses the level of protection
offered by seat belts and airbags.Your vehicle has five passenger places, two individual front seats and three
places on the rear seat. Each seat is equipped with a three-point seat belt.
The driver seat and front passenger seat can be adjusted in many ways to suit
the physical requirements of the vehicl e occupants. The correct seat position
is very important for:•
fast and easy operation of all controls on the instrument panel,
•
relaxed posture that does not cause drowsiness,
•
safe driving ⇒page 7,
•
and to ensure that the seat belts and airbag system provide maximum
protection ⇒page 19.
WARNING
•
If the driver and passengers assume improper sitting positions, they
may sustain critical injuries.
•
Never transport more people than there are seats available in the
vehicle.
•
Every occupant in the vehicle must properly fasten and wear the seat
belt belonging to his or her seat. Children must be protected with an appro-
priate child restraint system ⇒page 46, “Child safety”.
•
The front seats and all head restraints must always be adjusted to body
size and the seat belt must always be properly adjusted to provide you and
your passengers with optimum protection.
•
Always keep your feet in the foot well when the vehicle is moving; never
rest them on the dash panel, out of the window or on the seat. This also
applies to passengers. An incorrect sitting position exposes you to an
increased risk of injury in the event of a braking manoeuvre or an accident.
If the airbag is triggered, you could sustain severe injuries due to an incor-
rect sitting position.
•
It is important for the driver and front passenger to maintain a distance
of at least 25 cm from the steering wh eel or dash panel. Failure to respect
the minimum distance means that the airbag will not protect you. Risk of
fatal injury. The distance between the driver and the steering wheel or
between the front passenger and the dash panel should always be as great
as possible.
•
Adjust the driver or front passenger seat only when the vehicle is
stationary. Otherwise your seat could move unexpectedly while the vehicle
is moving. This could increase the risk of an accident and therefore injury.
In addition, while adjusting your seat, you will assume an incorrect sitting
position. Risk of fatal accidents.
•
Special guidelines apply to installing a child seat on the front
passenger seat. When installing a chil d seat, observe the warning note in
the ⇒page 46, “Child safety”.WARNING (continued)

WARNING
•
We recommend that you use only wheels and tyres that have been
approved by SEAT for your model. Fa ilure to do so could impair vehicle
handling. Risk of accident.
•
Avoid running the vehicle on tyres that are more than six years old. If
you have no alternative, you should drive slowly and with extra care at all
times.
•
Never use old tyres or those with an unknown “history of use”.
•
If wheel trims are retrofitted, you must ensure that the flow of air to the
brakes is not restricted. This could cause them to overheat.
•
All four wheels must be fitted with radial tyres of the same type, size
(rolling circumference) and the same tread pattern.For the sake of the environment
Old tyres must be disposed of according to the laws in the country concerned.
Note
•
For technical reasons, it is not generally possible to use the wheels from
other vehicles. This can also apply to wheels of the same model. The use of
wheels or tyres which have not been approved by SEAT for use with your
model may invalidate the vehicle's type approval for use on public roads.
•
If the spare tyre is not the same as the tyres that are mounted on the
vehicle - for example with winter tyres - you should only use the spare tyre for
a short period of time and drive with extra care. Refit the normal road wheel
as soon as possible.
Wheel bolts
Wheel bolts must be tightened to the correct torque.The design of wheel bolts is matched to the rims. If different wheel rims are
fitted, the correct wheel bolts with the right length and correctly shaped bolt
heads must be used. This ensures that wheels are fitted securely and that the
brake system functions correctly.
In certain circumstances, you may not use wheel bolts from a different car -
even if it is the same model ⇒page 191.
WARNING
If the wheel bolts are not tightened correctly, the wheel could become
loose while driving. Risk of accident.•
The wheel bolts must be clean and turn easily. Never apply grease or oil
to them.
•
Use only wheel bolts which belong to the wheel.
•
If the prescribed torque of the wheel bolts is too low, they could loosen
whilst the vehicle is in motion. Risk of accident! If the tightening torque is
too high, the wheel bolts and threads could be damaged.Caution
The prescribed torque for wheel bolts for steel and alloy wheels is 120 Nm.

220Winter tyres
Winter tyres will improve the vehicles handling on snow and
ice.In winter conditions winter tyres will considerably improve the vehicles
handling. The design of summer tyres (width, rubber compound, tread
pattern) gives less grip on ice and snow.
Winter tyres must be inflated to a pressure 0.2 bar higher than the pressures
specified for summer tyres (see sticker on tank flap).
Winter tyres must be fitted on all four wheels.
Information on permitted winter tyre sizes can be found in the vehicle's regis-
tration documents. Use only radial winter tyres. All tyre sizes listed in the
vehicle documentation also apply to winter tyres.
Winter tyres lose their effectiveness when the tread is worn down to a depth
of 4 mm.
The speed rating code ⇒page 218, “New tyres and wheels” determines the
following speed limits ⇒ :
Q max. 160 km/h
S max. 180 km/h
T max. 190 km/h
H max. 210 km/h
In some countries, vehicles which can exceed the speed rating of the fitted
tyre must have an appropriate sticker in the driver's field of view. These
stickers are available from your Authorised Service Centre. The legal require-
ments of each country must be followed.
Do not have winter tyres fitted for unnecessarily long periods. Vehicles with
summer tyres handle better when the roads are free of snow and ice.
If you have a flat tyre, please refer to the notes on the spare wheel
⇒ page 218, “New tyres and wheels”.
WARNING
The maximum speed for the winter tyres must not be exceeded. Otherwise,
this could lead to tyre damage and thus, an accident risk.
For the sake of the environment
Fit your summer tyres in good time. They are quieter, do not wear so quickly
and reduce fuel consumption.Snow chainsSnow chains may be fitted only to the front wheels, and only to certain tyre
sizes ⇒page 258.
Snow chains must have fine-pitch link s which do not protrude more that 9
mm, including tension device.
Remove wheel hub covers and trim rings before fitting snow chains. For safety
reasons cover caps, available in any Authorised Service Centre, must then be
fitted over the wheel bolts.
WARNING
Observe the fitting instructions provided by the snow chain manufacturer.
Caution
You must remove the snow chains to drive on roads which are free of snow.
Otherwise they will impair handling, damage the tyres and wear out very
quickly.

Compact temporary spare wheel*
The compact temporary spare wheel (spare wheel for vehicles
with no puncture repair kit) should only be used when really
necessary.The temporary spare wheel is stored under the floor panel in the luggage
compartment and is attached by a thumbnut.
How to use the compact temporary spare wheel
Should you ever have a punctured tyre, the compact temporary spare wheel
is only intended for temporary use until you can reach a workshop. The
standard-size road wheel should be replaced as soon as possible.
Please note the following restrictions when using the compact temporary
spare wheel. This spare wheel has been specially designed for your vehicle,
thus, it cannot be changed with th e spare wheel from another vehicle.
No other type of tyre (normal summer or winter tyre) may be fitted on the
compact temporary spare wheel rim. Snow chains
For technical reasons, snow chains must not
be used on the compact tempo-
rary spare wheel.
If you should have a puncture on one of the front wheels when using snow
chains, fit the compact temporary spare in place of one of the rear wheels.
You can then attach the snow chains to the wheel taken from the rear and use
this wheel to replace the punctured front wheel.
WARNING
•
The tyre pressures must be checked and corrected as soon as possible.
The tyre pressure for the spare wheel is 4.2 bar. Failure to do so could result
in an accident.
•
Do not drive faster than 80 km/h. High er speeds can cause an accident.
•
Avoid heavy acceleration, hard braking and fast cornering, risk of acci-
dent.
•
Never use two or more compact spare tyres at the same time, risk of
accident.
•
No other type of tyre (normal summer or winter tyre) may be fitted on
the compact temporary spare wheel rim.Note
•
Emergency wheels must never be used on vehicles fitted with Brembo
brakes. These vehicles are supplied with a tyre repair kit.
Tyre repair kit*
The tyre repair kit (for vehicles not including a spare wheel) is
stored under the floor panel in the luggage compartment.Your vehicle is equipped with the Tyre Mobility System “Tyre repair kit”.

If and when
224The tyre repair kit consists of a container with sealing compound to repair the
puncture and a compressor to generate the required tyre pressure. The kit will
reliably seal punctures up to a size of about 4 mm caused by the penetration
of a foreign body into the tyre.
Note
•
Seek professional assistance if the repair of a tyre puncture is not
possible with the sealing compound.
Wheel changePreparation work
What you must do before changing a wheel.– If you have a flat tyre or puncture, park the vehicle as far away from the flow of traffic as possible. Choose a location that is as
level as possible.
– All passengers should leave the ve hicle. They should wait in a
safe area (for instance behind the roadside crash barrier).
– Switch off the engine. Switch on the hazard warning lights.
–Apply the handbrake firmly.
– Engage the first gear, or put the selector lever to position P for
those vehicles with an automatic gearbox.
– If you are towing a trailer, unhitch it from your vehicle. –Take the
vehicle tools and the spare wheel out of the luggage
compartment.
WARNING
Put the hazard warning lights on and place the warning triangle in position.
This is for your own safety and also warns other road users.
Caution
If you have to change the wheel on a gradient, block the wheel opposite the
wheel being changed by placing a stone or similar object under it to prevent
the vehicle from rolling away.
Note
Please observe legal requirements when doing so.Changing a wheelChange the wheel as described below
–Pull off the hub cap. See ⇒ page 225, fig. 154.
– Slacken the wheel bolts
– Raise the car with the jack in the corresponding zone
– Ta k e o f f the wheel and then put on the spare wheel
– Lower the vehicle.

Snow chains
Snow chains may be fitted only to the
front wheels.
Consult the chapter “wheels” of this manual.
Wheel bolts
After the wheels have been changed, the tightening torque of the wheel bolts
should be checked as soon as possible with a torque wrench ⇒. The tight-
ening torque for steel and alloy wheels is 120 Nm.
WARNING
•
Check the tyre pressure at least once per month. Correct tyre pressure
is very important. If the tyre pressure is too high or too low, there is an
increased danger of accidents, particularly at high speeds.
•
If the torque of the wheel bolts is too low, they could loosen whilst the
vehicle is in motion. Risk of accident! If the tightening torque is too high,
the wheel bolts and threads could be damaged.Note
We recommend that you ask your Authorised Service Centre for information
about appropriate wheel, tyre and snow chain size.
