Wheels and tyres
Indications of wear
Tread wear indicators indicate if a tyre is worn.
Fig. 161 Tyre tread:
tread wear indicators
The original tyres on your vehicle have 1.6 mm high “tread wear indicators”
running across the tread. Depending on the manufacturer, there will be 6 to
8 of them spaced at equal distances around the tyre. Markings on the tyre
sidewall (for instance the letters “TWI” or a triangle) 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 indicators). (Different figures may apply in
other countries.)
WARNING
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.
● Especially in difficult driving conditions such as wet or icy roads, it is
important that the tyres have sufficient tread depth. The tread depth
should same on the tyres of both the front and the rear axles.
● The decrease in driving safety due to insufficient tread depth is par-
ticularly evident in handling of the vehicle, when there is a risk of “aqua-
planing” over deep puddles and when driving around corners. Braking is
also adversely affected.
● The speed has to be adapted accordingly, otherwise there is a risk of
losing control over the vehicle.

Wheels and tyres
If you use tyres that are approved by SEAT you can be sure that the actual
tyre dimensions will be correct for your vehicle. If you decide to fit a differ-
ent type of tyre, you must obtain the appropriate manufacturer's certificate
from the tyre retailer to confirm that the tyres are suitable for your vehicle.
Keep this certificate in a safe place.
Your SEAT Official Service will be able to advise you on which tyres may be
fitted to your vehicle.
It is best to have all servicing of wheels and tyres performed by a special-
ised workshop. 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.
WARNING
● It is very important to ensure that the tyres you have chosen have ad-
equate clearance. When selecting replacement tyres, do not rely entirely
on the nominal tyre size marked on the tyre; with some makes of tyre the
effective tyre size can differ significantly from the nominal dimensions,
even though the tyres have the same size designation. Inadequate tyre
clearance can result in damage to the tyres or the vehicle, causing a seri-
ous safety risk. It may also invalidate the vehicle's registration for use on
public roads.
● 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.
● If wheel trims are fitted after the car is purchased, ensure that there
is an adequate flow of air for cooling the brake system.
For the sake of the environment
Old tyres must be disposed of according to the laws in the country con-
cerned.
Note
● Never mount used tyres if you are not sure of their “previous history”.
● For technical reasons, it is not generally possible to use the wheels from
other vehicles. In some cases, this may also be true for the same model of
wheel. 
Wheel bolts
The wheel bolts are designed to suit the rims on your car.
The wheel bolts are matched to the rims. When installing different wheels
(for instance alloy wheels or wheels with winter tyres) it is important to use
the correct wheel bolts with the right length and correctly shaped bolt
heads. This ensures that wheels are fitted securely and that the brake sys-
tem functions correctly.
The wheel bolts must be clean and turn easily.
A special adapter is required to turn the anti-theft wheel bolts*
⇒ page 279. 
Winter tyres
Winter tyres will improve the vehicles handling on snow and
ice.
– Winter tyres must be fitted on all four wheels.
– Only use winter tyres that are approved for your vehicle.
– Please note that the maximum permissible speed for winter
tyres may be lower than for summer tyres. 
Safety FirstOperating instructionsPractical TipsTechnical specifications

270Wheels and tyres
–Also note that winter tyres are no longer effective when the
tread is worn down.
– After fitting the wheels you must always check the tyre pres-
sures. The correct tyre pressures are listed on the sticker on the
inside of the fuel tank flap ⇒ page 265.
In winter road conditions winter tyres will considerably improve vehicle han-
dling. The design of summer tyres (width, rubber compound, tread pattern)
gives less grip on ice and snow. This applies particularly to vehicles equip-
ped with wide section tyres or high speed tyres (code letters H, V or Y on
the sidewall).
Only use winter tyres of the correct type approved for your vehicle. The sizes
of the winter tyres approved for your vehicle are listed in the vehicle docu-
mentation (e.g. EC Certificate of Conformity or COC document 1)
). The vehicle
documentation varies depending on the country of residence. See also
⇒  page 268.
Winter tyres lose a great deal of their properties when the tread is worn
down to a depth of 4 mm.
The performance of winter tyres is also severely impaired by ageing, even if
the tread is still much deeper than 4 mm.
Winter tyres are subject to the following maximum speed limits according to
speed rating code letter: ⇒ 
Speed rating code letter

Q160 km/h (140 mph)S180 km/h (140 mph)T190 km/h (140 mph)
Speed rating code letter
⇒ page 268Maximum speed limit
H210 km/h (140 mph)
V240 km/h (150 mph)
(note restrictions)
Vehicles capable of exceeding these speeds must have an appropriate
sticker attached so that it is visible to the driver. Suitable stickers are availa-
ble from the SEAT Official Service and specialised workshop. Please note
regulations to this effect in your country.
“All-weather” tyres can also be used instead of winter tyres.
Using winter tyres with V-rating
Please note that the generally applicable 240 km/h (150 mph) speed rating
for winter tyres with the letter V is subject to technical restrictions; the max-
imum permissible speed for your vehicle may be significantly lower . The
maximum speed limit for tyres with a V-rating depends directly on the maxi-
mum axle weights for your car and on the listed weight rating of the tyres
being used.
It is best to contact a SEAT Official Service to check the maximum speed
which is permissible for the V-rated tyres fitted on your car on the basis of
this information.
WARNING
Exceeding the maximum speed permitted for the winter tyres fitted on
your car can cause tyre failure, resulting in a loss of control of the vehicle
– risk of accident. 

Accessories, replacement parts and repairs
Always ask your dealer or specialist retailer for advice be-
fore purchasing accessories and replacement parts.
Your vehicle is designed to offer a high standard of active and passive safe-
ty. For this reason, we recommend that you ask a SEAT Official Service for
advice before fitting accessories or replacement parts. Your SEAT Official
Service has the latest information from the manufacturer and can recom-
mend accessories and replacement parts which are suitable for your re-
quirements. They can also answer any questions you might have regarding
official regulations.
We recommend you to use only SEAT accessories and Genuine SEAT parts ®
.
SEAT has tested these parts and accessories for suitability, reliability and
safety. SEAT Official Services have the necessary experience and facilities to
ensure that the parts are installed correctly and professionally.
Any retro-fitted equipment which has a direct effect on the vehicle and/or
the way it is driven e.g. cruise control system or electronically-controlled
suspension, must bear the e mark (the European Union's authorisation
symbol) and be approved for use in the vehicle in question.
If any additional electrical components are fitted which do not serve to con-
trol the vehicle itself (for instance a refrigerator box, laptop or ventilator fan,
etc.), these must bear the  mark (manufacturer conformity declaration in
the European Union).
WARNING
Accessories, for example telephone holders or cup holders, should never
be fitted on the covers, or within the working range of the airbags. Other-
wise, there is a danger of injury if the airbag is triggered in an accident.
 Technical modifications
Modifications must always be carried out according to our
specifications.
Unauthorised modifications to the electronic components, software, wiring
or data transfer in the vehicle may cause malfunctioning. Due to the way the
electronic components are linked together in networks, other indirect sys-
tems may be affected by the faults. This can seriously impair safety, lead to
excessive wear of components, and also invalidate your vehicle registration
documents.
You will appreciate that your SEAT dealership cannot be held liable for any
damage caused by modifications and/or work performed incorrectly.
We recommend that all work should be performed by a SEAT Official Service
using Genuine SEAT parts
®
.
WARNING
Incorrectly performed modifications or other work on your vehicle can
lead to malfunctions and cause accidents.

● the aerial is installed correctly.
● the aerial is installed on the exterior of the vehicle (and shielded cables
are used together with non-reflective aerial trimming).
● the effective transmitting power does not exceed 10 Watts at the aerial
base.
A SEAT Official Service and specialised workshop will be able to inform you
about options for installing and operating radio transmitters with a higher
transmitting power.
Mobile radio transmitters
Commercial mobile telephones or radio equipment might interfere with the
electronics of your vehicle and cause malfunctions. This may be due to:
● no external aerial
● external aerial incorrectly installed
● transmitting power more than 10 W
You must, therefore, do not operate portable mobile telephones or radio
equipment inside the vehicle without a properly installed external aerial
⇒ 
.
Please note also that the maximum range of the equipment can only be ach-
ieved with an external aerial.
Business equipment
Retrofit installation of business or private equipment in the vehicle is per-
mitted, provided the equipment cannot interfere with the driver's immedi-
ate control of the vehicle and that any such equipment carries the  mark.
Any retrofit equipment that could influence the driver's control of the vehi-
cle must have a type approval for your vehicle and must carry the e mark.
WARNING
Mobile telephones or radio equipment which is operated inside the vehi-
cle without a properly installed external aerial can create excessive mag-
netic fields that could cause a health hazard.
Note
● The posterior fitting of electric and electronic equipment in this vehicle
affects its licence type and could lead to the withdrawal of the vehicle regis-
tration document under certain circumstances.
● Please use the mobile telephone/radio operating instructions. 

Repairing tyres
Fig. 164 Tyre: top up
Important: have the tyre repair kit ready ⇒ 
page 274.
Filling the tyre
– Before filling the tyre, shake the bottle of sealing product thor-
oughly.
– Screw the enclosed filling hose onto the sealant can as far as it
will go. This will pierce the foil sealing on the can. –
Take the valve cap off the tyre valve and use a screwdriver
⇒ Fig. 164 to unscrew the valve insert.
– Place the valve insert onto a clean surface.
– Remove the sealing plug from the filling hose and insert the
hose into the tyre valve.
– Hold the bottle upside down and insert the contents in the tyre
until the bottle is empty.
– Then disconnect the hose and screw the valve insert back onto
the tyre valve.
Inflating the tyre
– Screw the compressor filling hose (tyre repair kit) onto the tyre
valve and plug the connector into the 12V connection.
– Pump the tyre up to 2.0 to 2.5 bar and monitor the pressure
shown on the pressure gauge.
– If the tyre does not reach this pressure, move the car forwards
or backwards 10 metres to allow the sealing compound to
spread all around the tyre.WARNING
● Please observe the manufacturer's safety notes on the compressor
and the instructions supplied with the tyre sealant can.
● If, after six minutes of trying to inflate the tyre, it is not possible get
up to a pressure of 2.0 bar, this indicates that the tyre is too severely
damaged for repair with the kit. Do not carry on driving!
● If the tyre cannot be repaired with the sealing compound, seek pro-
fessional assistance. 
