–The tyre pressure should only be checked when the tyres are
cold. The slightly raised pressures of warm tyres must not be re-
duced.
– Adjust tyre pressure to the load being carried by the vehicle.
– In vehicles with a tyre pressure indicator, save the pressure of
modified tyres ⇒ page 214, ⇒ page 265.
– Avoid fast cornering and hard acceleration.
– Inspect the tyres for irregular wear from time to time.
The useful life of your tyres depends on the following factors:
Tyre pressure
Tyre pressure values are indicated on the inside of the fuel tank flap.
Insufficient or excessive pressure greatly reduces the useful life of the tyres
and adversely affects vehicle performance and ride. Correct inflation pres-
sures are very important, especially at high speeds.
If you want a more comfortable ride, you can inflate tyres to the pressure
corresponding to the normal vehicle load (up to 3 people) if the vehicle is
carrying a normal load. If the vehicle is going to carry the maximum load,
the tyre pressure should be increased to maximum value indicated.
The tyre pressure must be adjusted according to the load the vehicle is car-
rying. We recommend adhering to the tyre pressure specifications for a max-
imum load.
Do not forget the spare wheel when checking the tyre pressures: Keep the
spare wheel inflated to the highest pressure required for the road wheels.
In the case of a minimised temporary spare wheel (125/70 R16 or 125/70
R18) inflate to a pressure of 4.2 bar as indicated on the tyre pressure label
on the fuel tank flap. Driving style
Fast cornering, heavy acceleration and hard braking (squealing tyres) all in-
crease tyre wear.
Wheel balance
The wheels on new vehicles are balanced. However, certain circumstances
may lead to imbalance (run-out), which is detected as vibrations in the
steering wheel.
Unbalanced wheels should be rebalanced, as they otherwise cause exces-
sive wear on steering, suspension and tyres. A wheel must also be reba-
lanced when a new tyre is fitted or if a tyre is repaired.
Incorrect wheel alignment
Incorrect wheel alignment causes excessive tyre wear, impairing the safety
of the vehicle. If you notice excessive tyre wear, you should check wheel
alignment at a SEAT Official Service.
WARNING
● Always adapt the tyre pressure accordingly when the vehicle load
changes.
● A tyre with low air pressure has to flex a lot more when the vehicle is
heavily loaded or at high speeds, therefore causing overheating to occur.
Under these conditions, the tyre bead may be released or the tyre may
burst. Risk of accident!
For the sake of the environment
Under-inflated tyres will increase fuel consumption.

270Wheels 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 265.
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 vehicle
documentation varies depending on the country of residence. See also
⇒ page 268.
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 268Maximum speed limit
Q160 km/h (140 mph)S180 km/h (140 mph)T190 km/h (140 mph)
Speed rating code letter
⇒ page 268Maximum 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.
Extraction of the spare wheel in vehicles with SEAT SOUND
10 speakers (with subwoofer)*
– Disassemble the subwoofer’s floor panel (carpet) as follows:
– LEON / LEON SC model: first, pull the carpet in the direction of
the backrest and then pull the carpet upwards to remove it. LEON ST Model: lift and secure the luggage compartment floor
as explained in
⇒ page 148.
– Disconnect the subwoofer’s speaker cable.
– Turn the securing wheel anti-clockwise.
– Remove the subwoofer speaker and the spare wheel.
– When replacing the spare wheel, place the subwoofer speaker
in the direction indicated by the arrow and with the word
“FRONT” facing forward.
– Reconnect the speaker cable and firmly rotate the securing
wheel clockwise so that the subwoofer system and wheel are
firmly in place.
Jump starting Jump leads
The jump lead must have a sufficient wire cross section.
If the engine fails to start because of a discharged battery, the battery can
be connected to the battery of another vehicle to start the engine.
Jump leads
Jump leads must comply with standard DIN 72553 (see cable manufactur-
er's instructions). The wire cross section must be at least 25 mm 2
for petrol
engines and at least 35 mm 2
for diesel engines.

Towing a trailer Trailer weights
Trailer weight
The trailer weights and drawbar loads approved are selected in intensive tri-
als according to precisely defined criteria. The approved trailer weights are
valid for vehicles in the EU for maximum speeds of 80 km/h (50 mph) (in
certain circumstances up to 100 km/h, 60 mph). The figures may be differ-
ent in other countries. All data in the official vehicle documentation takes
precedence over these data at all times ⇒
.
Drawbar loads
The maximum permitted drawbar load on the ball joint of the towing bracket
must not exceed 80 kg.
In the interest of road safety, we recommend that you always tow approach-
ing the maximum drawbar load. The response of the trailer on the road will
be poor if the drawbar load is too small.
If the maximum permissible drawbar load cannot be met (e.g. with small,
empty and light-weight single axle trailers or tandem axle trailers with a
wheelbase of less than 1 metre), a minimum of 4% of the actual trailer
weight is legally required for the drawbar load.
WARNING
● For safety reasons, do not exceed the 80 km/h (50 mph) limit. This is
also valid in countries where higher speeds are permitted.
● Never exceed the maximum trailer weights or the drawbar load. If the
permissible axle load or the permissible total weight is exceeded, the
driving characteristics of the vehicle may change, leading to accidents,
injuries and damage to the vehicle.
Wheels
Tyre pressure, snow chains, wheel bolts
Tyre pressures
The sticker with the tyre pressure values can be found on the inside of the
fuel tank flap. The tyre pressure values given there are for cold tyres. The
slightly raised pressures of warm tyres must not be reduced. ⇒
Snow chains
Snow chains may be fitted only to the front wheels, and only for the follow-
ing tyres:
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
Wheel bolts
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
● Check the tyre pressure at least once per month. Checking the tyre
pressure is very important. If the tyre pressure is too high or too low,
there is an increased danger of accidents, particularly at high speeds.
● If the tightening torque of the wheel bolts is too low, they could loos-
en while the vehicle is in motion. Risk of accident! If the tightening tor-
que is too high, the wheel bolts and threads can be damaged.
