Airbag system
Airbag system
Brief introduction Why wear a seat belt and assume the correct sitting
position?
For the inflating airbags to achieve the best protection, the
seat belt must always be worn properly and the correct sit-
ting position must be assumed.For your own safety and the safety of the passengers, please en-
sure the following before driving:
– 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 correctly ⇒ page 13.
– Use the correct child restraint system to protect children in your
vehicle ⇒ page 47.
The airbag is deployed at high speed in fractions of a second. If you have an
incorrect seating position at the time the airbag is deployed, it could cause
you critical injuries. Therefore, it is essential that all passengers in the vehi-
cle assume a correct sitting position while travelling.
A sharp braking before an accident may cause a passenger not wearing a
seat belt to be thrown forward into the area of the deploying airbag. In this case, the inflating airbag may inflict critical or fatal injuries on the occupant.
This also applies 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 that will trigger an airbag are: the type of acci-
dent, the angle of collision and the speed of the vehicle.
Whether the airbags are triggered depends primarily on the vehicle deceler-
ation rate resulting from the collision and detected by the control unit. If the
vehicle deceleration occurring during the collision and measured by the
control unit remains below the specified reference values, the front, side
and/or curtain airbag will not be triggered. Take into account that the visible
damage in a vehicle involved in an accident, no matter how serious, is not a
determining factor for the airbags to have been triggered.
WARNING
● Wearing the seat belt incorrectly or assuming an incorrect sitting po-
sition 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. 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, if you lean forward or to the side
while travelling or assume an incorrect sitting position, there is a sub-
stantially increased risk of injury. This increased risk of injury will be fur-
ther increased if you are struck by an inflating airbag. 

198Intelligent technology
The traction control system (ASR) helps the car to start moving, accelerate
and climb a gradient in slippery conditions where this may otherwise be dif-
ficult or even impossible.
How it works
The ASR works automatically, i.e. without the driver's involvement. With the
aid of the ABS sensors , the ASR monitors the speed of the driven wheels
⇒ page 196. If the wheels start to spin, the engine speed is reduced auto-
matically to match the amount of grip available. The system is active across
the entire speed range.
The ASR works in conjunction with the ABS. If a failure occurs in the ABS,
the ASR will also stop working.
In general, the ASR should be left switched on at all times. It should only be
switched off manually in particular circumstances where a certain amount of
wheel slip may be desirable. Examples:
● when driving with snow chains
● when driving in deep snow or on loose surfaces
● when rocking the vehicle backwards and forwards to free it.
The ASR should be switched on again afterwards as soon as possible.
Note
To ensure that the ASR works properly, all four wheels must be fitted with
identical tyres. The difference in size of the wheels may lead to an unde-
sired reduction in engine power. Also see ⇒  page 255.Brakes
General notes
New brake pads
New brake pads do not provide optimal performance during the first
200 km; first they must be “run in”. However, the reduced braking capacity
may be compensated by pressing on the brake pedal a little harder. Avoid
overloading the brakes during run-in.
Wear
The rate of wear on the brake pads depends a great deal on how you drive
and the conditions in which the vehicle is operated. Negative factors are, for
instance, city traffic, frequent short trips or hard driving with abrupt starts
and stops.
Wet roads or road salt
In certain conditions, such as in heavy rain, or after washing the vehicle or
driving through water, the full braking effect can be delayed by moisture (or
in winter by ice) on the discs and brake pads. In this case the brakes should
be dried by pressing the brake pedal several times.
The effectiveness of the brakes can also be temporarily reduced if the vehi-
cle is driven for some distance without using the brakes when there is a lot
of salt on the road in winter. In this case, the layer of salt on the brake discs
and pads has to wear off before braking.
Corrosion
There may be a tendency for corrosion to form on the discs and dirt to build
up on the brake pads if the vehicle is used infrequently or the brakes are
not used very often.
If the brakes are not used frequently, or if rust has formed on the disks, it is
advisable to clean off the pads and disks by braking firmly a few times at a
moderately high speed ⇒

The tyres could also have the following information:
● A direction of rotation symbol
● “Reinforced” denotes heavy-duty tyres.
The manufacturing date is also indicated on the tyre sidewall (possibly only
on the inner side of the wheel).
“DOT... 1103...” means, for example, that the tyre was produced in the 11th
week of 2003.
We recommend that work on tyres and wheels be carried out by a Technical
Service. They are familiar with the procedure and have the necessary spe-
cial tools and spare parts as well as the proper facilities for disposing of the
old tyres.
Any Technical Service has full information on the technical requirements
when installing or changing tyres, wheels or wheel trims.
WARNING
● We recommend that you use only wheels and tyres which have been
approved by SEAT for your model. Failure to do so could impair vehicle
handling. Risk of accident.
● Avoid running the vehicle on tyres that are more than 6 years old. If
you have no alternative, you should drive slowly and with extra care at all
times.

TWARNING (Continued)
● 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 con-
cerned.
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 (e.g. winter tyres) you should only use the spare tyre for a short peri-
od 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 should not use wheel bolts from a different
vehicle, even if it is the same model ⇒ page 228.

Wheels and tyres
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 tightening torque for steel and alloy wheels is 120 Nm.
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 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 can be damaged.
CAUTION
The prescribed torque for wheel bolts for steel and alloy wheels is 120 Nm. 
Winter tyres
Winter tyres will improve the vehicles handling on snow and
ice.
In winter conditions winter tyres will considerably improve the vehicle's han-
dling. 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 pres-
sures 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 reg-
istration 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 255, New tyres and wheels determines the
following speed limits for winter tyres: ⇒ 
max. 160 km/h
max. 180 km/h
max. 190 km/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 Technical Service. The legal requirements 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 255, New tyres and wheels.
WARNING
The maximum speed for the winter tyres must not be exceeded. Other-
wise, this could lead to tyre damage and risk of accident.
For the sake of the environment
Fit your summer tyres again as soon as possible. They are quieter, do not
wear so quickly and reduce fuel consumption. 

Remove wheel hub covers and trim rings before fitting snow chains. For
safety reasons cover caps, available in any Technical Service, must then be
fitted over the wheel bolts.
WARNING
Observe the fitting instructions provided by the snow chain manufactur-
er.
CAUTION
Remove the snow chains to drive on roads without snow. Otherwise they
will impair handling, damage the tyres and wear out very quickly.
Note
● In some countries, the speed limit for using snow chains is 50 km/h.
The legal requirements of the country should be followed.
● We recommend that you ask your Technical Service for information
about appropriate wheel, tyre and snow chain size. 

If and when
Spare steel rim wheel
The spare steel rim wheel is carried in the wheel well under
the floor panel in the luggage compartment. It is only inten-
ded for temporary use over short distances.
Fig. 195 Spare steel rim
wheel
Taking out the spare wheel
– Turn the plastic knob ⇒ Fig. 195 anticlockwise.
– Take out the spare wheel.
Securing the defective wheel in the spare wheel well
– Place wheel in spare wheel well in the luggage compartment.
– Secure the wheel by turning plastic knob clockwise.
– Replace the floor panel before closing the rear lid.
Your vehicle can be factory-equipped with a spare steel wheel. The spare
wheel does not usually meet the same performance standards as the wheels fitted on the vehicle because of the wheel/tyre dimensions, rubber
composition, tread pattern, etc. Therefore, note the following restrictions:
●
The spare steel wheel is designed only for your vehicle model. Do not
attempt to mount the wheel on any vehicle but your own.
● Your vehicle will have different driving characteristics when the spare
steel rim wheel is mounted ⇒ 
.
● The spare wheel is only intended for temporary use after having a flat
tyre. Replace the spare wheel with a normal wheel that has the proper tyre
dimensions as soon as possible.
● If the size of the spare steel rim wheel is different to that of the other
wheels, it is unlikely that snow chains suitable for the other wheels will fit it.
WARNING
● After mounting the spare steel rim wheel, the tyre pressure must be
checked and corrected as soon as possible. The tyre pressure must corre-
spond to the vehicle load (consult the table containing the inflation pres-
sures). Otherwise there is danger of causing an accident. Use the highest
tyre pressure as indicated in the table.
● Do not drive faster than 80 km/h, as higher speeds can cause an acci-
dent.
● Avoid heavy acceleration, hard braking and fast cornering, as this
could cause an accident.

Description of specifications
Drawbar load
The maximum permitted drawbar load on the ball joint of the towing bracket
must not exceed 75 kg.
In the interest of road safety, we recommend that you always tow approach-
ing the maximum drawbar load. The response of the trailer on the road will
be poor if the drawbar load is too small.
If the maximum permissible drawbar load cannot be met (e.g. with small,
empty and light-weight single axle trailers or tandem axle trailers with a
wheelbase of less than 1 metre), a minimum of 4% of the actual trailer
weight is legally required for the drawbar load.
WARNING
● For safety reasons, do not exceed the 80 km/h limit. This is also valid
in countries where higher speeds are permitted.
● Never exceed the maximum trailer weights or the drawbar load. If the
permissible axle load or the permissible total weight is exceeded, the
driving characteristics of the vehicle may change, leading to accidents,
injuries and damage to the vehicle.

Tyre pressure, snow chains, wheel bolts
Tyre pressures
The sticker with the tyre pressure values can be found on the inside of the
tank flap. The tyre pressure values given there are for cold tyres. The slightly
raised pressures of warm tyres must not be reduced. ⇒ 
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 tightening torque for steel and alloy wheels is 120 Nm.
WARNING
● Check the tyre pressure at least once per month. Checking the 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 while the
vehicle is in motion. Risk of accident! If the tightening torque is too high,
the wheel bolts and threads can be damaged.
Note
We recommend that you ask your Technical Service for information about
appropriate wheel, tyre and snow chain size. 
