The service life of tyres is dependent on tyre pressure, driving
style and fitting.
Wear indicators
The original tyres on your vehicle have 1.6 mm high “tread wear indicators”
⇒ page 192, fig. 129 , running across the tread. Depending on the make,
there will be six to eight of them evenly spaced around the tyre. Markings on
the tyre sidewall (for instance the lett ers “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 indica-
tors). 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 191.
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 advisable
to change them around as shown ⇒page 192, fig. 130. 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 results
in steering vibration.
Unbalanced wheels should be rebalanced, as they otherwise cause excessive
wear on steering, suspension and tyres. A wheel must also be rebalanced
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 align-
ment 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 is worn down to
the tread wear indicators. 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.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 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:
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 indicate d 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 wh eels 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 wh eels and tyres which have been
approved by SEAT for your model. Failure to do so could impair vehicle
handling. Risk of accident.

194•
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 according 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 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 may not use wheel bolts from a different car -
even if it is the same model
⇒page 167.
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 prescribed 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 ty res (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 193, “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 u nnecessarily 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 193, “New tyres and wheels”.
WARNING
The maximum speed for the winter tyre s must not be exceeded. Otherwise,
this could lead to tyre damage and thus, an accident risk.
For the sake of the environment
Fit your summer tyres in good time. They are quieter, do not wear so quickly
and reduce fuel consumption.
Snow chainsSnow chains are only permitted on th e front wheels and only for tyres 155/80
R13; 165/70 R14 and 185/80 R14. Snow ch ains must have fine-pitch links
which do not protrude more than 15 mm, including tension device.
Remaining tyres can be fitted with chains no thicker than 9 mm.
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
Observe the fitting instructions provided by the snow chain manufacturer.
Caution
You must remove the snow chains to drive on roads which are free of 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.

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.
•
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.
Tyre repair kit*
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”.
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.
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.
– Take the vehicle tools and the spare wheel out of the luggage
compartment.

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. 134.
– 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. 135.
– 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. 134 . 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.
