design of summer tyres (width, rubber com-
pound, 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 specified in the vehicle's documents
(e.g. EC Certificate of Conformity or COC
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
stamped on all winter tyres
Vehicles capable of exceeding these speeds
must have an appropriate sticker attached
so that it is visible to the driver. Suitable stick-
ers are available from the SEAT Official Serv-
ice and specialised workshop. Please note
the regulations to this effect in your country.
"All-weather" tyres can also be used instead
of winter tyres.
1) COC = certificate of conformity.

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 re-
strictions; the maximum permissible speed
for your vehicle may be significantly lower.
The maximum speed limit for these tyres de-
pends 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 SEAT Official Service to
check the maximum speed which is permissi-
ble 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 con-
trol of the vehicle – risk of accident.

For the sake of the environment
When winter is over, change back to sum-
mer tyres at an appropriate moment. In
temperatures above +7°C (+45°F), perform-
ance will be improved if summer tyres are
used. Fuel consumption, wear and noises
while driving will all be reduced.
Practical tips
Snow chains
Snow chains must only be fitted to the front
wheels, even on vehicles with four-wheel
drive.
Check that they are correctly seated after
●
driving for a few yards; correct the position if
necessary, in accordance with the manufac-
turer's fitting instructions.
Keep your speed below 50 km/h (30 mph).
●
If there is a danger of being trapped de-
●
spite having mounted the chains, it is best to
disable the driving wheels (ASR) in the ESC
›››
page 304, Connecting and disconnect-
ing the ESC and ASR.
Snow chains will improve braking ability as
well as traction in winter conditions.
For technical reasons snow chains may only
be used with the following wheel rim/tyre
combination.
215/65 R17 Chains with links of maximum 9 mm
Other dimensions do not allow chains
Remove any central wheel trims and the rim
ring before fitting snow chains.
