Wear indicators
The original tyres on your vehicle have 1.6 mm high “tread wear indicators”
⇒ fig. 152, running across the tread. Depending on the make, there will be
6 to 8 of them evenly spaced around the tyre. Markings on the tyre sidewall
(for instance the letters “TWI” or other symbols) indicate the positions of
the tread wear indicators. The minimum tread depth required by law is
1.6 mm (measured in the tread grooves next to the tread wear indicators).
Worn tyres must be replaced. Different figures may apply in export countries
⇒ 
.
Tyre pressure
Incorrect tyre pressure causes premature wear and could cause tyre blow-
out. For this reason, the tyre pressure should be checked at least once per
month ⇒ page 233.
Driving style
Fast cornering, heavy acceleration and hard braking all increase tyre wear.
Changing wheels around
If the front tyres are worn considerably more than the rear ones it is advisa-
ble to change them around as shown ⇒ fig. 153. All the tyres will then last
for about the same time.
Wheel balance
The wheels on new vehicles are balanced. However, various factors encoun-
tered in normal driving can cause them to become unbalanced, which re-
sults in steering vibration.
Unbalanced wheels should be rebalanced, as they otherwise cause exces-
sive wear on steering, suspension and tyres. A wheel must also be reba-
lanced when a new tyre is fitted. Incorrect wheel alignment
Incorrect wheel alignment causes excessive tyre wear, impairing the safety
of the vehicle. If tyres show excessive wear, you should have the wheel
alignment checked by an Authorised Service Centre.
WARNING
There is a serious danger of accidents if a tyre bursts during driving!
● The tyres must be replaced at the latest when the tread wear indica-
tors are worn ⇒ page 236. Failure to do so could result in an accident.
Worn tyres do not grip well at high speeds on wet roads. There is also a
greater risk of aquaplaning.
● At continuously high speeds, a tyre with insufficient pressure flexes
more. This causes it to overheat. This can cause tread separation and tyre
blow-out. Risk of accident. Always observe the recommended tyre pres-
sures.
● If tyres show excessive wear, you should have the running gear
checked by an Authorised Service Centre.
● Keep chemicals such as oil, fuel and brake fluid away from tyres.
● Damaged wheels and tyres must be replaced immediately!
For the sake of the environment
Under-inflated tyres will increase fuel consumption. 

Wheels and tyres
Run-flat tyres
Run-flat tyres allow you to continue driving even with a
punctured tyre, in the majority of cases.
In vehicles that are factory-fitted with run-flat tyres 1)
the loss of tyre
pressure is indicated on the instrument panel.
Driving with run-flat tyres (emergency running)
– Leave the ESC (ESP)/ASR (TCS) (Electronic Stability Control) acti-
vated, or activate it ⇒ page 183.
– Continue driving carefully and slowly (80 km/h maximum).
– Avoid sudden manoeuvres and sharp turns.
– Avoid driving over obstacles (for example kerbs) or potholes.
– Look out for the ESC (ESP)/ASR (TCS) intervening often, smoke
coming from the tyres or the smell of rubber, the vehicle vibrat-
ing or a clattering noise. If any of these occur, stop the vehicle.
The run-flat tyres have a tag on the side of the tyre, with the description:
“DSST”, “Eufonia”, “RFT”, “ROF”, “RSC”, “SSR” or “ZP”.
The sides of this type of tyre are reinforced. When the tyres lose air they are
supported on the sides (emergency driving).
The loss of pressure in the tyre is shown on the instrument panel. You can
then drive a maximum of 80 km and if the circumstances are favourable (for
example, low load), even more.
The damaged tyre should be changed as soon as possible. The rim should
be checked in a specialist workshop to detect possible damage and replace it if necessary. We recommend you contact Technical Service. If more than
one tyre is being used under emergency conditions, this reduces the dis-
tance which can be travelled.
Starting driving in emergency conditions
When loss in tyre pressure is displayed on the instrument panel, this means
that at least one tyre is being driven in emergency conditions
⇒ 
.
End of emergency operation
Do not drive on if:
● smoke is coming from one of the tyres,
● there is a smell of rubber,
● the vehicle vibrates,
● there is a rattling noise.
When is it no longer possible to continue driving even using run-flat tyres?
● If one of the tyres has been severely damaged in an accident, etc. If a
tyre has been badly damaged there is a risk that parts of the tread can be
thrown off and cause damage to the fuel lines, brake pipes or fuel filler.
● It is also advisable to stop driving if severe vibrations occur, or if the
wheel starts overheating and gives off smoke.
WARNING
When driving in emergency conditions, the driving quality of the vehicle
is considerably impaired.
● The maximum permitted speed of 80 km/h is subject to road and
weather conditions. Please observe legal requirements when doing so.
● Avoid sharp turns and rapid manoeuvres, and brake earlier than usu-
al. 

WARNING (Continued)
● Avoid driving over obstacles (for example kerbs) or potholes.
● If one or more tyres are being driven in emergency conditions, the
driving quality of the vehicle is impaired and there is a risk of accident.
Note
● The run-flat tyres do not “deflate” on losing pressure because they are
supported on the reinforced sides. Therefore defects in the tyre cannot be
detected with a visual inspection.
● Snow chains must not be used on front tyres used in emergency condi-
tions. 
New tyres and wheels
New tyres and wheels have to be run in.
The tyres and wheel rims are an essential part of the vehicle's design. The
tyres and rims approved by SEAT are specially matched to the characteris-
tics of the vehicle and make a major contribution to good road holding and
safe handling ⇒ 
.
Tyres should be replaced at least in pairs and not individually (i.e. both front
tyres or both rear tyres together). A knowledge of tyre designations makes it
easier to choose the correct tyres. Radial tyres have the tyre designations
marked on the sidewall, for example: 195/65 R15 91T
This contains the following information: Tyre width in mm
Height/width ratio in %
Tyre construction: Radial
195
65
R Rim diameter in inches
Load rating code
Speed rating
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 an Author-
ised Service Centre. They are familiar with the procedure and have the nec-
essary special tools and spare parts as well as the proper facilities for dis-
posing of the old tyres.
Any Authorised Service Centre has full information on the technical require-
ments 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.
● 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. 

240Wheels and tyres
The speed rating code ⇒ page 238, 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 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 238, 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. 
Snow chains
Snow chains are only permitted on front wheels and only for tyres
195/65R15 and 205/55R16. These tyres may only be fitted with fine-pitch
link chains which do not protrude more than 15 mm ⇒ page 272. For
235/35R19 tyres, the use of snow chains is not permitted. Q
S
T
H Other tyres may use fine-pitch links which do not protrude more than 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
Snow chains should be correctly tightened in accordance with the manu-
facturer's instructions. This will prevent the chains coming into contact
with the wheel housing.
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 Authorised Service Centre for informa-
tion about appropriate wheel, tyre and snow chain size. 

247
If and when
Removing and fitting the wheel
For removal and fitting the wheel, the following tasks must
be completed.
After loosening the wheel bolts and raising the vehicle with the
jack, change the wheel as described below:
Removing a wheel
– Unscrew the wheel bolts using the box spanner and place them
on a clean surface.
Fitting a wheel
– Screw on the wheel bolts in position and tighten them loosely
with a box spanner.
The wheel bolts should be clean and easily screwed. Before fitting the spare
wheel, inspect the wheel condition and hub mounting surfaces. These sur-
faces must be clean before fitting the wheel.
If tyres with a specific direction of rotation are fitted, note the direction of
rotation. Anti-theft wheel bolts*A special adapter is required to turn the anti-theft wheel
bolts.
Fig. 159 Anti-theft
wheel bolt
– Insert the adapter onto the wheel bolt and push it on as far as it
will go ⇒ fig. 159.
– Fit the box spanner as far as it will go over the adapter.
– Loosen or tighten the wheel bolt as appropriate.
Code
The code number of the anti-theft wheel bolt is stamped onto the front part
of the adaptor.
The code number should be noted and kept in a safe place, as it is only by
using the code number that a duplicate adaptor can be obtained from an
Authorised Service Centre. 

248If and when
Tyres with directional tread pattern
Tyres with directional tread pattern must be fitted so that
they rotate in the correct direction.
A directional tread pattern can be identified by arrows on the sidewall that
point in the direction of rotation. Always note the direction of rotation indi-
cated when fitting the wheel. This is important so that these tyres can give
maximum grip and avoid excessive noise, tread wear and aquaplaning.
If, in an emergency, you have to mount the spare wheel so it rotates in the
wrong direction, you must drive extremely carefully. The tyre will not give
optimum performance. This is particularly important when driving on wet
roads.
To benefit from the advantages of tyres with this type of tread pattern, the
defective tyre should be replaced as soon as possible so that all tyres again
rotate in the correct direction. 
Tyre repair kit (Tyre Mobility System)* General information and safety notes
Your vehicle is equipped with a tyre repair kit called Tyre Mobility System.
In the event of a tyre puncture, a sealing compound and an air compressor
are located in the luggage compartment under the floor panel.
The Tyre Mobility System will reliably seal punctures caused by the penetra-
tion of a foreign body of up to about 4 mm in diameter.
It is not necessary to remove the foreign body from the tyre.
Instructions for the sealing compound are located on the sealing compound
container. You will also find instructions for operating the compressor.
WARNING
● Do not attempt to repair a puncture with the sealing compound if the
tyre has been damaged by driving the vehicle after the tyre has lost its
air.
● Always observe warnings and follow instructions concerning com-
pressor and sealing compound carefully.
● Do not drive faster than 80 km/h, avoid heavy acceleration, hard
braking and fast cornering.
● Tyres which have been repaired with sealing compound are only suit-
able for temporary use over a short period. Therefore, please drive care-
fully to the next available specialised workshop.
For the sake of the environment
If you have to dispose of a sealant can, go to a specialised waste service or
to a SEAT Technical Service, where the product can be recycled in an appro-
priate waste container.
Note
● If sealant should leak out, leave it to dry. This way you can pull it off like
a piece of foil.
● Observe the expiry date stated on the sealing compound can. Have the
sealing compound exchanged by a specialised workshop.
● Seek professional assistance if the repair of a tyre puncture is not possi-
ble with the sealing compound. 

251
If and when
The electric windows are protected by circuit breakers. These reset automat-
ically after a few seconds when the overload (caused for example by frozen
windows) has been corrected.
Fuses colour code

WARNING
Never “repair” damaged fuses and never replace them with fuses with a
higher rating. Failure to comply could result in fire. This could also cause
damage to other parts of the electrical system.
Note
● If a newly replaced fuse blows again after a short time, the electrical sys-
tem must be checked by a specialised workshop as soon as possible.
● If you replace a fuse with higher-rating fuse, you could cause damage to
another location in the electrical system. ●
Always keep some spare fuses in the vehicle. These are available from
SEAT dealers.
● In addition to the fuses listed in the following tables, there are other
fuses which must be replaced by the Technical Service Workshop. 

272Description 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.

Wheels
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. Do not re-
duce the slightly raised pressures of warm tyres ⇒ 
.
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 Authorised Service Centre for information
about appropriate wheel, tyre and snow chain size. 
