Tyre monitoring systems Introduction
Additional information and warnings:
● SEAT information system ⇒  page 73
● Caring for and cleaning the vehicle exterior ⇒ page 198
● Wheels and tyres ⇒ page 223
● Accessories, parts replacement, repairs and modifications ⇒ page 230
WARNING
Unsuitable handling of the wheels and tyres may lead to sudden tyre
pressure losses, to tread separation or even to a blow-out.
● Check tyre pressures regularly and ensure they are maintained at the
pressures indicated. Tyre pressure that is too low could cause overheat-
ing, resulting in tread detachment or even burst tyres.
● Tyre pressure should be that indicated on the label when the tyres are
cold at all times ⇒ page 266.
● Regularly check the cold inflation pressure of the tyres. If necessary,
change the tyre pressure of the vehicle tyres while they are cold.
● Regularly check your tyres for damage and wear.
● Never exceed the maximum permitted speed or loads specified for the
type of tyre fitted on your vehicle.
For the sake of the environment
Under-inflated tyres lead to increased fuel consumption and tyre wear.
Note
● Driving for the first time with new tyres at a high speed can cause them
to slightly expand, which could then produce an air pressure warning.
● Only replace used tyres with those authorised by SEAT for the corre-
sponding type vehicle.
● Do not only rely on the tyre monitoring system. Regularly check your
tyres to ensure that the tyre pressure is correct and that the tyres are not
damaged due to puncture, cuts, tears and impacts/dents. Remove objects
from the tyres only when they have not pierced the tyres. 

Fuel
Types of petrol
The correct grade of petrol is listed inside the fuel tank flap.
The vehicle is equipped with a catalytic converter and must only be run on
unleaded petrol. The petrol must comply with European Standard EN 228 or
German standard DIN 51626-1 and must be unleaded. You can refuel with a
maximum ethanol proportion of 10 % (E10). The types of petrol are differen-
tiated by their octane rating (RON).
The following titles appear on the corresponding adhesive on the fuel tank
flap:
Super unleaded 95 octane or normal 91 octane unleaded petrol
We recommend you use super 95 octane petrol. If this is not available: nor-
mal 91 octane petrol, with a slight decrease in power.
Super unleaded petrol with a minimum of 95 octanes
You should use super petrol with a minimum of 95 octanes.
If super is not available, in an emergency you may refuel with normal 91 oc-
tane petrol. In this case only use moderate engine speeds and a light throt-
tle. Refuel with super as soon as possible.
Super unleaded 98 octane or super 95 octane unleaded petrol
We recommend you use super plus 98 octane petrol. If this is not available:
super 95 octane petrol, with a slight decrease in power.
If super is not available, in an emergency you may refuel with normal 91 oc-
tane petrol. In this case only use moderate engine speeds and a light throt-
tle. Refuel with super as soon as possible.
CAUTION
● Never refuel with fuels containing a large proportion of ethanol (for ex-
ample, E50, E85). This could damage the fuel system.
● Just filling one full tank of leaded fuel or fuel containing other metal ad-
ditives would seriously impair the efficiency of the catalytic converter.
● Only use fuel additives that have been approved by SEAT. Octane boost-
ing or anti-knock additives may contain metal additives that could seriously
damage the engine or the catalytic converter. These additives must not be
used.
● Do not refuel if the filler indicates that the fuel contains metal. LRP (lead
replacement petrol) fuels also contain high concentrations of metal addi-
tives. This could damage the engine!
● High engine speed and full throttle can damage the engine when using
petrol with an octane rating lower than the correct grade for the engine.
Note
● You may use petrol with a high octane number than the one recommen-
ded for your engine.
● In those countries where unleaded petrol is not available, you may refuel
with a fuel with a low lead content. 

222Checking and refilling levels
● Insert a new blade of the same length and type in the rear wiper arm in
the opposite direction to the arrow B
and hook into place button 1.
● Replace the wiper arm on the rear window.
WARNING
Worn or dirty wiper blades reduce visibility and increase the risk of acci-
dent and serious injury.
● Always replace damaged or worn blades or blades which do not clean
the windscreen correctly.
CAUTION
● Damaged or dirty windscreen wipers could scratch the glass.
● If products containing solvents, rough sponges or sharp objects are
used to clean the blades, the graphite layer will be damaged.
● Never use fuel, nail varnish remover, paint thinner or similar products to
clean the windows. 

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. 

228Wheels 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 223.
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 vehi-
cle documentation varies depending on the country of residence. See also
⇒ page 226.
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 ⇒ page 226Maximum speed limit
Q160 km/h (140 mph)S180 km/h (140 mph)T190 km/h (140 mph)
Speed rating code
letter ⇒ page 226Maximum 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. 

Emergencies
– Take out the temporary spare wheel.
Chains
For technical reasons, snow chains must not be used on the temporary
spare wheel.
If you have a puncture on one of the front wheels when using snow chains,
fit the temporary spare wheel in place of one of the rear wheels. Fit the snow
chains on the rear wheel that you have removed and replace the punctured
front wheel with this wheel.
WARNING
● After fitting the temporary spare wheel, check the tyre pressures as
soon as possible. Failure to do so may cause an accident. The tyre pres-
sures are listed on the inside of the fuel tank flap.
● Do not drive at over 80 km/h (50 mph) when the temporary spare
wheel is fitted on the vehicle: risk of accident!
● Avoid heavy acceleration, hard braking and fast cornering: risk of ac-
cident!
● Never use more than one temporary spare wheel 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.
