The windscreen wiper blades are supplied as standard with a layer of graph-
ite. This layer is responsible for ensuring that the wipe is silent. If the graph- ite layer is damaged, the noise of the water as it is wiped across the wind-
screen will be louder.
Check the condition of the wiper blades regularly.
If the wipers scrape
across the glass they should be changed if they are damaged, or cleaned if
they are dirty ⇒ 
.
Damaged wiper blades should be replaced immediately. Wiper blades are
available from specialised workshops.
Raising/lowering windscreen wiper arms
For windscreen wipers, please note: the wiper should be in service position
before being lowering ⇒ page 119. When raising or lowering an arm, it should only be held at the blade fasten-
ing point.
Cleaning windscreen wiper blades
● Raising the wiper arms.
● Use a soft cloth to remove dust and dirt from the windscreen wiper
blades.
● If the blades are very dirty, a sponge or damp cloth may be used ⇒ 
.

General notes
– When driving with new tyres, be especially careful during the
first 500 km (300 miles).
– If you have to drive over a kerb or similar obstacle, drive very
slowly and as near as possible at a right angle to the obstacle.
– Check from time to time if the tyres are damaged (punctures,
cuts, cracks or dents). Remove any foreign objects embedded in
the treads.
– Damaged wheels and tyres must be replaced immediately.
– Keep grease, oil and fuel off the tyres.
– Replace any missing valve caps as soon as possible.
– Mark the wheels before taking them off so that they rotate in
the same direction when put back.
– When removed, the wheels or tyres should be stored in a cool,
dry and preferably dark place.
New tyres
New tyres do not give maximum grip straight away and should therefore be
“run in” by driving carefully and at moderate speeds for about the first 500
km (300 miles). This will also increase the useful life of the tyres. The tread depth of new tyres may
vary, according to the type and make of
tyre and the tread pattern.
Concealed damage
Damage to tyres and rims is often not readily visible. If you notice unusual
vibration or the car pulling to one side, this may indicate that one of the
tyres is damaged. Reduce speed immediately if there is any reason to sus-
pect that damage may have occurred. Inspect the tyres for damage. If no ex-
ternal damage is visible, drive slowly and carefully to the nearest special-
ised workshop and have the car inspected.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the direction of rotation on single
drive tyres. Always note the direction of rotation indicated when mounting
the wheel. This guarantees optimum grip and helps to avoid aquaplaning,
excessive noise and wear.
Retrofitting Accessories
If you wish to change or fit wheels, rims or wheel trims, we recommend that
you consult with a SEAT Official Service centre for advice regarding current
techniques. 
Useful life of tyres
Correct inflation pressures and sensible driving habits will
increase the useful life of your tyres.
– Check tyre pressure at least once a month, and also prior to any
long trip. 

Wheels and tyres
Indications of wear
Tread wear indicators indicate if a tyre is worn.
Fig. 115 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 vehicle handling, when there is a risk of aquaplaning
in deep puddles of water and when driving through 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 237. 
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. 

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 (30 mph).
– 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 184, 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
Only use snow chains with fine-pitch links. The links must not protrude
more than 13.5 mm from the tyres (including tensioner).
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, 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 be approved for use in your vehicle and bear the e mark
(the European Union's authorisation symbol).
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.

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. 
