COC = certicate of conformity.
• Please note that the maximum permissible
speed for winter tyres may be lower than for
summer tyres.
•
Also note that winter tyres are no longer ef-
fective when the tread is worn down.
•
After tting the wheels you must always
check the tyre pressures. When doing so,
take into account the correct tyre pressures
listed on the rear of the front left door frame
››› page 295.
In winter road conditions winter tyres will con-
siderably improve vehicle handling. The design
of summer tyres (width, rubber compound,
tread pattern) gives less grip on ice and snow.
This applies particularly to vehicles equipped
with wide section tyres or with high speed
tyres (code letters H, V or Y on the sidewall).
Only use winter tyres of the correct type ap-
proved for your vehicle. The sizes of these
tyres are specied in the vehicle's documents
(e.g. EC Certicate of Conformity or COC
1 )
).
The vehicle documentation varies depending
on the country of residence.
Winter tyres lose a great deal of their proper-
ties when the tread is worn down to a depth of
4 mm.
The performance of winter tyres is also se-
verely impaired by ageing, even if the tread is
still much deeper than 4 mm.
A code letter indicating the speed limit is stam-
ped on all winter tyres

In the infotainment system's
Vehicle settings
menu, a speed warning can be set in the Tyres
menu.
Vehicles capable of exceeding these speeds
must have an appropriate sticker attached so
that it is visible to the driver. Suitable stickers
are available at specialised CUPRA Services,
SEAT Oicial Service centres and specialised
workshops. Please note the regulations to this
eect 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 (149 mph) speed for winter tyres with
the letter V is subject to technical restric-
tions; the maximum permissible speed for
your vehicle may be signicantly lower. The
maximum speed limit for these tyres depends
directly on the maximum axle weights for your
car and on the listed weight rating of the tyres
being used.
It is best to contact a specialised CUPRA Serv-
ice or SEAT Oicial Service to check the max-
imum speed which is permissible for the V-
rated tyres tted on your car on the basis of
this information.
WARNING
Exceeding the maximum speed permitted for
the winter tyres tted on your car can cause
tyre failure, resulting in a loss of control of
the vehicle – risk of accident.
NOTICE
When winter is over, change back to summer
tyres at an appropriate moment. In tempera-
tures above +7°C (+45°F), performance will be
improved if summer tyres are used. Rolling
noise, wear and energy consumption will all
be reduced.
Snow chains
Snow chains may only be tted to the rear
wheels.
•
Check that they are correctly seated after
driving for a few yards; correct the position
if necessary, in accordance with the manufac-
turer's tting instructions.
•
Keep your speed below 50 km/h (30 mph).
Snow chains will improve braking ability as well
as traction in winter conditions.
For technical reasons, the use of snow chains
is only permitted on the following rim and tyre
combinations:
