246Wheels and tyres
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 a Technical Service.
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 245. 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 a Technical Service.
● 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. 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/ASR on (Electronic Stability Control), or switch it
on ⇒  page 69.
– Continue driving carefully and slowly (80 km/h maximum).
– Avoid sudden manoeuvres and sharp turns.
– Avoid driving over obstacles (for example kerbs) or potholes.
– Pay attention if the ESC/ASR activates often, if smoke comes
from the tyres or there is a smell of rubber, if the vehicle vi-
brates or there are clattering noises. 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. 

Wheels and tyres
The damaged tyre should be changed as soon as possible. The rim should
be checked in a specialised workshop to detect possible damage and re-
place it if necessary. We recommend you contact Technical Service. If more
than one tyre is being used under emergency conditions, this reduces the
distance 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 the Electronic Stability Control (ESC) does not function.
● If the tyre pressure monitoring system* does not work.
● 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.
WARNING (Continued)
● Avoid sharp turns and rapid manoeuvres, and brake earlier than usu-
al.
● 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: 
Safety FirstOperating InstructionsPractical TipsTechnical Specifications

Tyre width in mm
Height/width ratio in %
Tyre construction: Radial
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 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 221.


249
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 247, 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 247, 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 may be fitted only to the front wheels, and only to certain tyre
sizes ⇒ page 295.
205/55 R1615 mm chains225/45 R179 mm chains225/40 R187 mm chains
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
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. 185 Anti-theft
wheel bolt
– Insert the adapter onto the wheel bolt and push it on as far as it
will go ⇒ Fig. 185.
– 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 the
SEAT Official Services. 

If and when
The sealing compound must not be used in the following cases:
● If the cuts and punctures on the tyre are longer than 4 mm ⇒ Fig. 186 1
●
If the wheel rim has been damaged 2●
If you have been driving with very low pressure or a completely flat tyre

How to use the TMS (tyre mobility system) is described in the section Re-
pairing a tyre ⇒ page 260 and in the instructions supplied with the tyre
sealant can.
The TMS (tire mobility system) can be used at outside temperatures down
to -20 °C.
WARNING
After repairing a tyre please note the following points:
● Do not drive faster than 80 km/h.
● Avoid heavy acceleration, hard braking and fast cornering.
● Vehicle handling could be impaired.
● Tyres which have been sealed using the Tyre Mobility System are only
suitable for temporary use over a short period.
● After using the tyre sealant the tyre pressure monitoring system* may
malfunction. Therefore, please drive carefully to the next available speci-
alised workshop.
● The Tyre Mobility System must NOT be used:
– If the cuts and punctures on the tyre are longer or wider than
4 mm.
– if the wheel rim has been damaged.
– if you have been driving with very low pressure or a completely flat
tyre.
● Seek professional assistance if the repair of a tyre puncture is not
possible with the sealing compound.
WARNING (Continued)
● Do not allow the sealant to come into contact with your eyes, skin or
clothing.
● If you do come into contact with the sealant immediately rinse the
eyes or skin affected with clean water.
● Change clothing immediately if it becomes soiled with the tyre seal-
ant.
● Make sure you do not breathe in the fumes!
● If any of the tyre sealant is accidentally ingested, immediately rinse
the mouth thoroughly and drink lots of water.
–Do not induce vomiting. Seek medical assistance if needed.
● If any allergic reactions should occur get medical help immediately.
● Keep the sealant away from children.
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. 

Bulbs
General information
You can change the following bulbs for exterior lights yourself:
● Main headlights: all bulbs (except xenon headlights)
● Tail lights: all bulbs
● Side turn signal bulb
The following bulbs can only be changed by a specialised workshop:
● Main headlights: Xenon* bulb ⇒ page 271
● Front fog lights: Bulb
As a rule, you require a certain degree of practical skill to change defective
bulbs. This applies in particular to those bulbs which are only accessible
from the engine compartment.
If in doubt, we recommend that you have defective bulbs changed by a spe-
cialised workshop or qualified mechanic.
If you do decide to change bulbs in the engine compartment yourself, be
aware of the safety risks involved ⇒ page 227 ⇒ 
in Types of bulbs on
page 265. The name of many of the lamps fitted by SEAT ends in "LL". This means Long
Life. These lamps are used for functions with a long service time (dipped
beam, side lights, daylight driving, etc.). This does not apply to lamps with
a shorter service time (turn signals, etc.). A lamp with the same name ex-
cept for the last two letters, "LL“ or “SLL”, is compatible, but will have a
service life of approximately half of the LongLife lamps.
When replacing lamp bulbs, the same type of bulb as originally fitted
should always be used where possible.

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.

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. 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. 
