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: 

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 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. 

Snow chains
Snow chains may be fitted only to the front wheels, and only to certain tyre
sizes ⇒ page 303.
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
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.

Changing a wheel
Preparation 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 vehicle. They should wait in a
safe place (e.g. behind the roadside crash barrier).
– Apply the handbrake firmly.
– Engage first gear .
– When towing a trailer: Unhitch the trailer from your vehicle.
– Take the tools and the spare wheel ⇒  page 259 out of the lug-
gage compartment.
WARNING
If you have a puncture in heavy traffic, switch on the hazard warning
lights and place the warning triangle in a visible location. This is for your
own safety and also warns other road users.
CAUTION
If you have to change the tyre 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. 
