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

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 210.
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 237, “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 237, “New tyres and wheels”.

Wheel changePreparation 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 area (for instance behind the roadside crash barrier).
– Switch off the engine. Switch on the hazard warning lights.
–Apply the handbrake firmly.
–Engage the first gear, or put the selector lever to position P for
those vehicles with an automatic gearbox.
– If you are towing a trailer, unhitch it from your vehicle.

Raising the vehicle
The vehicle must be raised with a jack to remove the wheel.
– Locate the jacking point under the door sill closest to the wheel
being changed ⇒fig. 178.
– Wind up the jack under the jacking point until the arm of the jack is directly below the vertical rib under the door sill.
– Align the jack so that the arm of the jack fits around the rib under the door sill and the movable base plate of the jack is flat on the
ground ⇒fig. 179.
– Raise the vehicle until the defect ive wheel is just clear of the
ground.Recesses at the front and rear of the door sills mark the jacking points
⇒ fig. 178 . A position has been made for each wheel. Do not fit the jack
anywhere else.
An unstable surface under the jack may cause the vehicle to slip off the jack.
Therefore, the jack must be fitted on solid ground offering good support. Use
a large and stable base, if necessary. On a hard, slippery surface (such as
tiles) use a rubber mat or similar to prevent the jack from slipping.
WARNING
•
Take all precautions so that the base of the jack does not slip. Failure to
do so could result in an accident.
•
The vehicle can be damaged if the jack is not applied at the correct
jacking points. There is also a risk of injury since the jack can slip off
suddenly if it is not properly engaged.

The wheel bolts should be clean and turn easily. Before fitting the spare
wheel, inspect the condition of the wheel and hub mounting surfaces. These
surfaces must be clean
before fitting the wheel.
The hexagonal socket in the screwdriver handle makes it easier to turn the
wheel bolts when they are loose. The reversible screwdriver blade should be
removed when the tool is used for this purpose.
If tyres with a specific direction of rotation are fitted, note the direction of
rotation.
Note
Do not use the hexagonal socket in the screwdriver handle to loosen or
tighten the wheel bolts.Anti-theft wheel bolts
A special adapter is required to turn the anti-theft wheel
bolts.
– Insert the adapter onto the wheel bolt and push it on as far as it will go ⇒fig. 182.
– Fit the box spanner as far as it will go over the adapter.
– Loosen or tighten the wheel bolt as appropriate.Error code
The code number of the anti-theft wheel bolt is stamped on the front 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 duplicat e adaptor can be obtained from an
Authorised Service Centre.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 ident ified 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 fit the spare wheel so it rotates in the wrong
direction, you must drive extremely care fully. 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.
