WARNING (Continued)
● If wheel trims are retrofitted, you must ensure that the flow of air to
the brakes is not restricted. This could cause the brake system to over-
heat.
● All four wheels must be fitted with radial tyres of the same type, size
(rolling circumference) and the same tread pattern.
For the sake of the environment
Old tyres must be disposed of according to the laws in the country con-
cerned.
Note
● For technical reasons, it is not generally possible to use the wheels from
other vehicles. This can also apply to wheels of the same model. The use of
wheels or tyres which have not been approved by SEAT for use with your
model may invalidate the vehicle's type approval for use on public roads.
● If the spare tyre is not the same as the tyres that are mounted on the
vehicle (e.g. winter tyres) you should only use the spare tyre for a short peri-
od of time and drive with extra care. Refit the normal road wheel as soon as
possible.
Wheel bolts
The design of wheel bolts is matched to the rims. If different wheel rims are
fitted, the correct wheel bolts with the right length and correctly shaped
bolt heads must be used. This ensures that wheels are fitted securely and
that the brake system functions correctly.
In certain circumstances, you should not use wheel bolts from a different
vehicle, even if it is the same model ⇒ p age 195.
Safety Operation
After the wheels have been changed, the tightening torque of the wheel
bolts should be checked as soon as possible with a torque wrench ⇒
The tightening torque for steel and alloy wheels is 120 Nm.
WARNING
If the wheel bolts are not tightened correctly, the wheel could become
loose while driving. Risk of accident.
● The wheel bolts must be clean and turn easily. Never apply grease or
oil to them.
● Use only wheel bolts which belong to the wheel.
● If the tightening torque of the wheel bolts is too low, they could loos-
en whilst the vehicle is in motion. Risk of accident! If the tightening tor-
que is too high, the wheel bolts and threads can be damaged.
CAUTION
The prescribed tightening torque for wheel bolts for steel and alloy wheels
is 120 Nm.

Winter tyres
In winter conditions winter tyres will considerably improve the vehicle's han-
dling. The design of summer tyres (width, rubber compound, tread pattern)
gives less grip on ice and snow.
Winter tyres must be inflated to a pressure of 0.2 bar (2.9 psi/20 kPa) high-
er than the pressures specified for summer tyres (see sticker on fuel tank
flap).
Winter tyres must be fitted on all four wheels.
Information on permitted winter tyre sizes can be found in the vehicle's reg-
istration documentation. Use only radial winter tyres. All tyre sizes listed in
the vehicle documentation also apply to winter tyres.
