WARNING (Continued)
● Seat belts should be completely dry before retracting. Damp could
damage the belt retractor so that it is does not operate correctly.
● Do not allow liquids or foreign bodies to enter the buckle fastenings.
This could damage the buckles and seat belts.
● Never attempt to repair, modify or remove a seat belt yourself.
● Always have damaged seatbelts replaced immediately by seat belts
approved for the vehicle in question by SEAT. Seat belts which have been
worn in an accident and stretched must be replaced by a specialised
workshop. Renewal may be necessary even if there is no apparent dam-
age. The belt anchorage should also be checked.

About your tyres and wheels
Fig. 123 Diagram for
changing wheels
The tyres of a vehicle are the components which are subjected to most
stress and are the most underestimated. Tyres are very important, as the
support offered by their narrow surface is the only point of contact between
the vehicle and the road.
The service life of tyres is dependent on tyre pressure, driving style, the care
they receive and the correct fitting.
The tyres and wheel rims are an essential part of the vehicle's design. The
tyres and rims approved by SEAT are specially matched to the characteris-
tics of the vehicle and our critical to good road holding and safe handling.
Avoiding damage to tyres and wheels
● 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 kerb.
● Inspect the tyres regularly for damage (punctures, cuts, cracks, dents).
● Remove any foreign bodies found on the outside of the tread provided
they have not passed through the wall of the tyre
⇒  page 216.
● The instructions for tyre control systems should always be observed. ●
Replace damaged or worn tyres as soon as possible ⇒ page 216.
● Regularly check tyres for non-visible damage ⇒ page 216.
● Never exceed the maximum permitted speed or loads specified for the
type of tyre fitted on your vehicle ⇒ page 218.
● Do not allow tyres (including the spare wheel) to come into contact with
aggressive substances, grease, oil, fuel or brake fluid ⇒ 
.
● Lost valve caps should be replaced immediately.
Tyres with directional tread pattern
Tyres with directional tread pattern have been designed to operate best
when rotating in only one direction. An arrow on the tyre sidewall indicates
the direction of rotation on tyres with directional tread ⇒ page 218. Always
observe the direction of rotation indicated when mounting the wheel. This
guarantees optimum grip and helps to avoid aquaplaning, excessive noise
and wear.
If the tyre is mounted in the opposite direction of rotation, drive with ex-
treme caution, as the tyre is no longer being used correctly. This is of partic-
ular importance when the road surface is wet. Change the tyre as soon as
possible or remount it with the correct direction of rotation.
Interchanging tyres
To ensure that the wear is equal on all tyres the wheels should be changed
round from time to time according to the system ⇒ Fig. 123. The useful life
of all the tyres will then be about the same time.
SEAT recommends you take the vehicle to a specialised workshop to have
the tyres changed.
Tyres that are over 6 years old
Tyres are subject to an ageing process as a result of physical and chemical
processes. This may affect their performance. Tyres which are stored for
long periods of time without being used, harden and become more fragile
than tyres which are in constant use.
SEAT recommends that tyres over six years old are replaced with new tyres.
This also applies to tyres (including the spare wheel) which appear to be in 

Vehicle care and maintenance
WARNING
The use of worn or damaged wheel rims could make driving more danger-
ous and result in serious accidents and damage.
● Only wheel rims which have been approved for use with your vehicle
should be used.
● Inspect wheel rims regularly for damage and replace as required.
WARNING
If the bolted joints of wheel rims with bolted ring trims are not correctly
tightened or loosened, this could result in serious accident.
● Never loosen the bolted joints of wheel rims with bolted ring trims.
● Any work relating to wheel rims with bolted rims should be carried
out at specialised workshop. SEAT recommends visiting a Technical Serv-
ice.

Replacement of new tyres and wheel rims
New tyres
● When tyres are new, drive with extreme caution for the first 600 km
(400 miles), as all tyres need to be run-in. Tyres which have not been run-in
do not have such good grip ⇒ 
or braking capacity ⇒ .
● All four wheels must be fitted with radial tyres of the same type, size
(rolling circumference) and the same tread pattern.
● The tread depth of new tyres may vary, according to the type and make
of tyre and the tread pattern. Replacing tyres
●
Where possible, always replace both wheels on an axle (both wheels on
the front axle or both wheels on the rear axle) ⇒ 
.
● Only replace used tyres with those authorised by SEAT for the corre-
sponding type vehicle. Pay special attention to size, diameter, and maxi-
mum load and speed capacity.
● Never use tyres which are larger than SEAT approved tyres. If the tyres
are too big, they may knock or rub against the chassis or other components,
resulting in damage.
WARNING
New tyres do not give maximum grip and will not have reached their max-
imum braking capacity to start with, and therefore need running in.
● To prevent accidents and major damage, extreme caution should be
taken for the first 600 km (400 miles).
WARNING
There should be adequate space between the tyres and the vehicle in ac-
cordance with the vehicle design. If this is not the case, the tyres may
rub against parts of the running gear, chassis or brake lines, leading to
faults in the brake system or to tread detachment, and the risk of burst
tyres.
● The true tyre dimension should not be greater than the dimensions of
tyres manufactured and approved by SEAT and should not rub against
parts of the vehicle.
Note
Although tyres may be shown as being the same size, the true dimensions
of different types of tyre may vary with respect to the nominal size, or tread
patterns may be different. 

Vehicle care and maintenance
Checking tyre pressures
Check tyre pressures only when the vehicle has not been driven for more
than a few kilometres at low speeds in the past three hours.
● The tyre pressures should be checked regularly, and only when the tyres
are cold. Always check all tyres, including the spare wheel. Tyre pressures
should be checked more often in colder regions, and only when the vehicle
has not been driven recently. Always use a correctly-operating tyre gauge.
● Adjust tyre pressures to the loads carried in the vehicle.
● After adjusting the tyre pressure, check that the caps are properly
screwed.
The spare wheel or temporary spare wheel must be at the maximum pres-
sure specified.
WARNING
If tyre pressures are too high or too low, the tyre may deflate or burst
suddenly while driving. This could result in a serious accident.
● If the tyre pressure is too low, the tyres could overheat, resulting in
tread detachment or even burst tyres.
● When driving at high speeds and/or fully loaded, the tyre could sud-
denly overheat, burst or be subject to tread detachment, with the resul-
tant loss of control of the vehicle.
● Tyre pressures which are too high or too low reduce the service life of
the tyre, affecting the vehicle's performance.
● Tyre pressures should be checked regularly, at least once a month
and before long journeys.
● Adjust the pressures of all the tyres to the vehicle load.
● Never deflate excess pressure from hot tyres.
CAUTION
● Take care not to tilt the manometer when placing it on the valve. Other-
wise, the valve may be damaged.
● To avoid damage to the valves, always replace valve caps correctly.
Check that the caps are identical to the standard caps and have been cor-
rectly tightened.
For the sake of the environment
Under-inflated tyres will increase the fuel consumption. 
Tread depth and wear indicators

tread wear indicators
Tread depth
Certain driving conditions require a deeper tread, as well as needing the
tread to be approximately the same on the front and rear tyres. This is par-
ticularly important when driving in winter, in cold temperatures and on wet
roads ⇒

Vehicle care and maintenance
Running gear settings : an incorrectly positioned running gear increases the
wear of tyres and affects your safety while driving. If tyres wear too quickly,
have the wheel alignment checked at a specialised workshop.
WARNING
If you notice unusual vibration or the car pulls to one side while driving,
this may indicate that one of the tyres is damaged.
● Reduce speed immediately and stop, while observing the highway
code.
● Check the wheels and tyres for damage.
● Never carry on driving on worn tyres or wheels. Request qualified as-
sistance immediately.
● If there is no visible exterior damage, drive slowly and carefully to the
nearest specialised workshop and have the vehicle checked.

● If necessary, remove the luggage compartment variable floor ⇒ page 98.
● Lift up the carpet from the recess and remove it from the luggage com-
partment.
● If necessary, take out the vehicle tool kit with the container.
● Completely remove the hand controlled wheel from the centre of the
spare wheel ⇒ Fig. 126 by turning it in an anticlockwise direction, and take
out the spare wheel.
Storing the replaced wheel
● Pull back the carpet.
● With the wheel rim facing downwards, situate the replaced wheel in the
spare wheel well so that the wheel rim central hole coincides with the open-
ing.
● Turn the hand controlled wheel with the shank screwed clockwise until
the replaced wheel is secured.
● If necessary, store the vehicle tool in the container, inside the luggage
compartment.
● Replace the carpet on the luggage compartment floor.
● Lower the rear shelf.
● Close the rear lid.
If the spare wheel is different to the rest of the vehicle tyres
If the spare tyre is not the same as the tyres that are mounted on the vehicle
- for example with winter tyres or the temporary spare wheel - you should
only use the spare tyre for a short period of time and drive with extra care
⇒ 
.
Refit the normal road wheel as soon as possible.

Vehicle care and maintenance
Remove wheel hub covers and trim rings before fitting snow chains ⇒ 
.
The wheel bolts should be covered with caps for safety reasons. These are
available from Technical Services.
Temporary spare wheel
For technical reasons, snow chains must not be used on the compact tem-
porary spare wheel ⇒ page 217.
If it is necessary to fit chains with the temporary spare wheel in use, install
the temporary spare wheel on the rear axle in the event of a fault in a front
wheel. Then, fit the rear wheel that is free, instead of the damaged front
wheel. In this situation, observe the rotating direction of the wheels. SEAT
recommends attaching the snow chains before fitting the wheel.
WARNING
The use of unsuitable or incorrectly fitted chains could lead to serious ac-
cidents and damage.
● Always the appropriate snow chains.
● Observe the fitting instructions provided by the snow chain manufac-
turer.
● Never exceed the maximum permitted speeds when driving with snow
chains.
CAUTION
● Remove the snow chains to drive on roads without snow. Otherwise they
will impair handling, damage the tyres and wear out very quickly.
● Wheel rims may be damaged or scratched if the chains come into direct
contact with them. SEAT recommends the use of covered snow chains.
Note
Snow chains are available in different sizes according to the vehicle type. 
