Wheels and tyres
For the sake of the environment
Summer tyres should be fitted again as soon as possible; they give better
handling on roads which are free of snow and ice. Summer tyres perform
with less rolling noise, tyre wear and – most important – reduce fuel con-
sumption. 
Snow chains
Snow chains will improve vehicle handling on snow-covered
roads.
– Snow chains can be used on the front wheels only.
– Check that the snow chains are correctly seated after driving for
a few yards. Always take the manufacturer assembly instruc-
tions into account.
– Keep your speed below 50 km/h.
– If there is a danger of being trapped despite having mounted
the chains, it is best to disable the driving wheels (ASR) in the
ESC ⇒ page 223, Switching on/off the ESC and ASR.
Snow chains will improve braking ability as well as traction in winter condi-
tions.
For technical reasons snow chains may only be used with the following
wheel rim/tyre combination.
195/65 R15Chains with links of maximum 15 mm205/55 R16Chains with links of maximum 15 mm225/45 R17Chains with links of maximum 9 mm225/40 R18Chains with links of maximum 9 mm
Remove wheel covers and trim rings before fitting snow chains.
Remove the chains when roads are free of snow. Otherwise they will impair
handling, damage the tyres and wear out very quickly. 

Accessories and modifications to the vehicle
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.

Radio transmitters and business equipment
Radio transmitters (fixed installation)
Any retrofit installations of radio transmitters in the vehicle require prior ap-
proval. SEAT generally authorises in-vehicle installations of approved types
of radio transmitters provided that: 

Accessories and modifications to the vehicle
● 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. 

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. 
