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 distance
which can be travelled.
Starting driving in emergency conditions
At the moment the loss of tyre pressure is indicated on the instrument panel,
at least one of the tyres is driving in emergency mode
⇒.
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 anti-puncture
tyres?
•
If the Electronic Stabilisation Pro gram (ESP) is out of operation.
•
If the tyre pressure monitoring system is out of operation.
•
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 usual.
•
Avoid driving over obstacles (for example kerbs) or potholes.
•
If one or more tyres is being driven in emergency conditions, the driving
quality of the vehicle is impaired and there is a risk of accident.Note
•
The anti-puncture tyres do not “deflate” on losing pressure because they
are supported on the reinforced sides. Therefore defects in the tyre can not be
detected with a visual inspection.
•
Snow chains must not be used on front tyres used in emergency
conditions.
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 characteristics
of the vehicle and make a major contribution to good road holding and safe
handling ⇒.
Tyres should be replaced at least in pair s and not individually (i.e. both front
tyres or both rear tyres together). A knowledge of tyre designations makes it
leon ingles.book Seite 225 Dienst ag, 11. September 2007 1:47 13

Wheels and tyres
226easier 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:
195 Tyre width in mm
65 Height/width ratio in %
R Tyre construction: Radial
15 Rim diameter in inches
91 Load rating code
T 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 is carried out by an Authorised
Service Centre. They are familiar with the procedure and have the necessary
special tools and spare parts as well as the proper facilities for disposing 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 six years old. If
you have no alternative, you should dr ive 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 accordi ng 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 ex tra 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 199.
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
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 could 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 vehicles
handling. The design of summer tyre s (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 225, “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 225, “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.

230Compact temporary spare wheel*
The compact spare wheel (emergency wheel for vehicles
without the anti-puncture kit) should only be used when
strictly 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 restrictio ns 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. Higher 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
•
Vehicles with Brembo brakes must never use emergency wheels. These
vehicles have a sit for repairing tyres.
Tyre repair ki t*
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”.

Te c h n i c a l D a t a
The tyre repair kit consists of a contai
ner 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.
