242Wheels and tyres
Wear indicators
The original tyres on your vehicle have 1.6 mm high “tread wear indicators”
⇒ Fig. 166, running across the tread. Depending on the make, there will be
6 to 8 of them evenly spaced around the tyre. Markings on the tyre sidewall
(for instance the letters “TWI” or other symbols) indicate the positions of
the tread wear indicators. The minimum tread depth required by law is
1.6 mm (measured in the tread grooves next to the tread wear indicators).
Worn tyres must be replaced. Different figures may apply in export countries
⇒
.
Tyre pressure
Incorrect tyre pressure causes premature wear and could cause tyre blow-
out. For this reason, the tyre pressure should be checked at least once per
month ⇒ page 239.
Driving style
Fast cornering, heavy acceleration and hard braking all increase tyre wear.
Changing wheels around
If the front tyres are worn considerably more than the rear ones it is advisa-
ble to change them around as shown ⇒ Fig. 167. The useful life of all the
tyres will then be about the same time.
Wheel balance
The wheels on new vehicles are balanced. However, various factors encoun-
tered in normal driving can cause them to become unbalanced, which re-
sults in steering vibration.
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. Incorrect wheel alignment
Incorrect wheel alignment causes excessive tyre wear, impairing the safety
of the vehicle. If tyres show excessive wear, you should have the wheel
alignment checked by a Technical Service.
WARNING
There is a serious danger of accidents if a tyre bursts during driving!
● The tyres must be replaced at the latest when the tread wear indica-
tors are worn ⇒ page 242. Failure to do so could result in an accident.
Worn tyres do not grip well at high speeds on wet roads. There is also a
greater risk of aquaplaning.
● At continuously high speeds, a tyre with insufficient pressure flexes
more. This causes it to overheat. This can cause tread separation and tyre
blow-out. Risk of accident. Always observe the recommended tyre pres-
sures.
● If tyres show excessive wear, you should have the running gear
checked by a Technical Service.
● Keep chemicals such as oil, fuel and brake fluid away from tyres.
● Damaged wheels and tyres must be replaced immediately!
For the sake of the environment
Under-inflated tyres will increase fuel consumption.

Wheels and tyres
Run-flat tyres
Run-flat tyres allow you to continue driving even with a
punctured tyre, in the majority of cases.
In vehicles that are factory-fitted with run-flat tyres 1)
the loss of tyre
pressure is indicated on the instrument panel.
Driving with run-flat tyres (emergency running)
– Leave the ESC/ASR on (Electronic Stability Control), or switch it
on ⇒ page 189.
– Continue driving carefully and slowly (80 km/h (50 mph) maxi-
mum).
– Avoid sudden manoeuvres and sharp turns.
– Avoid driving over obstacles (for example kerbs) or potholes.
– Pay attention if the ESC/ASR activates often, if smoke comes
from the tyres or there is a smell of rubber, the vehicle vibrates
or there are clattering noises. If any of these occur, stop the ve-
hicle.
The run-flat tyres have a tag on the side of the tyre, with the description:
“DSST”, “Eufonia”, “RFT”, “ROF”, “RSC”, “SSR” or “ZP”.
The sides of this type of tyre are reinforced. When the tyres lose air they are
supported on the sides (emergency driving).
The loss of pressure in the tyre is shown on the instrument panel. You can
then drive a maximum of 80 km (50 miles) and if the circumstances are fa-
vourable (for example, low load), even more. The damaged tyre should be changed as soon as possible. The rim should
be checked in a specialised workshop to detect possible damage and re-
place it if necessary. We recommend you contact Technical Service. If more
than one tyre is being used under emergency conditions, this reduces the
distance which can be travelled.
Starting driving in emergency conditions
When loss in tyre pressure is displayed on the instrument panel, this means
that at least one tyre is being driven in emergency conditions
⇒
.
End of emergency operation
Do not drive on if:
● smoke is coming from one of the tyres,
● there is a smell of rubber,
● the vehicle vibrates,
● there is a rattling noise.
When is it no longer possible to continue driving even using run-flat tyres?
● If one of the tyres has been severely damaged in an accident, etc. If a
tyre has been badly damaged there is a risk that parts of the tread can be
thrown off and cause damage to the fuel lines, brake pipes or fuel filler.
● It is also advisable to stop driving if severe vibrations occur, or if the
wheel starts overheating and gives off smoke.

Wheels and tyres
WARNING
● We recommend that you use only wheels and tyres which have been
approved by SEAT for your model. Failure to do so could impair vehicle
handling. Risk of accident.
● Avoid running the vehicle on tyres that are more than 6 years old. If
you have no alternative, you should drive slowly and with extra care at all
times.
● Never use old tyres or those with an unknown history of use.
● 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
Wheel bolts must be tightened to the correct torque.
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 ⇒ page 217.
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.

How to use the temporary spare wheel
Should you ever have a punctured tyre, the temporary spare wheel is only
intended for temporary use until you can reach a workshop. The standard-
size road wheel should be replaced as soon as possible.
Please note the following restrictions when using the temporary spare
wheel. This temporary spare wheel has been specially designed for your ve-
hicle, thus, it cannot be changed with the temporary spare wheel from an-
other vehicle.
No other type of tyre (normal summer or winter tyre) may be fitted on the
compact temporary spare wheel rim.
Snow chains
For technical reasons, snow chains must not be used on the compact tem-
porary spare wheel.
If you have a puncture on one of the front wheels when using snow chains,
fit the compact temporary spare wheel in place of one of the rear wheels.
You can then attach the snow chains to the wheel taken from the rear and
use this wheel to replace the punctured front wheel.
WARNING
● The tyre pressures must be checked and corrected as soon as possi-
ble after fitting the temporary spare wheel. The temporary spare wheel
pressure for dimensions 125/70R16 125/70R18 135/90R16 is 4.2 bar;
for all other tyre dimensions please refer to the label on the fuel cap. Fail-
ure to do so could result in an accident.
● Do not drive faster than 80 km/h (50 mph). Higher speeds can cause
an accident.
● Avoid heavy acceleration, hard braking and fast cornering. Risk of ac-
cident.
WARNING (Continued)
● 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.
Tyre repair kit
The tyre repair kit (for vehicles not including a temporary
spare wheel) is stored under the floor panel in the luggage
compartment. In the event of a punctured tyre, your vehicle is equipped with the Tyre Mo-
bility System tyre repair kit.
The tyre repair kit consists of a container with sealing product to repair the
puncture and a compressor to generate the required tyre pressure. The kit
will reliably seal punctures up to a size of about 4 mm caused by the pene-
tration of a foreign body into the tyre.
Note
● Seek professional assistance if the repair of a tyre puncture is not possi-
ble with the sealing product.

Wheel change
Preparation work
What you must do before changing a wheel.
– If you have a flat tyre or puncture, park the vehicle as far away
from the flow of traffic as possible. Choose a location that is as
level as possible.
– All vehicle occupants should leave the vehicle. They should
wait in a safe area (for instance behind the roadside crash barri-
er).
– Switch off the engine. Switch on the hazard warning lights.
– Apply the handbrake firmly.
– Engage the first gear , or put the selector lever to position P for
those vehicles with an automatic gearbox.
– If you are towing a trailer, unhitch it from your vehicle.
– Take the vehicle tools and the spare wheel out of the luggage
compartment.
WARNING
Put the hazard warning lights on and place the warning triangle in posi-
tion. This is for your own safety and also warns other road users.
CAUTION
If you have to change the tyre on a gradient, block the wheel opposite the
wheel being changed by placing a stone or similar object under it to prevent
the vehicle from rolling away.
Note
Please observe legal requirements when doing so.
Changing a wheel
Change the wheel as described below
– Pull off the hub cap. Also see ⇒ page 251.
– Slacken the wheel bolts .
– Raise the vehicle with the jack at the corresponding point.
– Remove the wheel and then fit the spare wheel.
– Lower the vehicle.
– Tighten the wheel bolts firmly with the box spanner.
– Replace the hub cap.
After changing a wheel
After changing the wheel there are still tasks to complete. – Put the tools and jack back in the luggage compartment.
253
If and when
WARNING
Loosen the wheel bolts only about one turn before raising the vehicle
with the jack, otherwise there is a risk of accident.
Note
● If the wheel bolt is very tight, you may be able to loosen it by pushing
down the end of the spanner carefully with your foot. Hold on to the vehicle
for support and take care not to slip.
Raising the vehicle
In order to remove the wheel, the vehicle must be raised
with a jack.
Fig. 171 Jack position
points
Fig. 172 Fitting the jack
– Locate the jacking point under the door sill closest to the wheel
to be changed ⇒ Fig. 171.
– Place the jack under the jacking point and turn the crank until
the arm of the jack is directly below the vertical rib under the
door sill.
– Align the jack so that the arm of the jack fits around the rib un-
der the door sill and the movable base plate of the jack is flat
on the ground ⇒ Fig. 172.
– Raise the jack until the defective wheel is just clear of the
ground.
Recesses at the front and rear of the door sills mark the jacking points
⇒ Fig. 171. There is only one jacking point for each wheel. Do not fit the jack
anywhere else.
An unstable surface under the jack may cause the vehicle to slip off the
jack. Therefore, the jack must be fitted on solid ground offering good sup-
port. Use a large and stable base, if necessary. On a hard, slippery surface
(such as tiles) use a rubber mat or similar to prevent the jack from slipping.
Safety FirstOperating InstructionsPractical TipsTechnical Specifications
254If and when
WARNING
● Take all precautions so that the base of the jack does not slip. Failure
to do so could result in an accident.
● The vehicle can be damaged if the jack is not applied at the correct
jacking points. There is also a risk of injury since the jack can slip off
suddenly if it is not properly engaged.

Once the cover has been released, it will remain connected to
its strap so that is not lost.
Removing and fitting the wheel
For removal and fitting the wheel, the following tasks must
be completed.
After loosening the wheel bolts and raising the vehicle with the
jack, change the wheel as described below:
Removing a wheel
– Unscrew the wheel bolts using the box spanner and place them
on a clean surface.
Fitting a wheel
– Screw on the wheel bolts in position and tighten them loosely
with a box spanner.
The wheel bolts should be clean and easily screwed. Before fitting the spare
wheel, inspect the wheel condition and hub mounting surfaces. These sur-
faces must be clean before fitting the wheel.
If tyres with a specific direction of rotation are fitted, note the direction of
rotation.
256If and when
You will also find instructions for operating the compressor.
WARNING
● Do not attempt to repair a puncture with the sealing product if the
tyre has been damaged by driving the vehicle after the tyre has lost its
air.
● Always observe warnings and follow instructions concerning com-
pressor and sealing compound carefully.
● Do not drive faster than 80 km/h (50 mph), avoid heavy acceleration,
hard braking and fast cornering.
● Tyres which have been repaired with sealing compound are only suit-
able for temporary use over a short period. Therefore, please drive care-
fully to the next available specialised workshop.
For the sake of the environment
If you have to dispose of a sealant can, go to a specialised waste service or
to a SEAT Technical Service, where the product can be recycled in an appro-
priate waste container.
Note
● If sealing product should leak out, leave it to dry. This way you can pull it
off like a piece of foil.
● Observe the expiry date stated on the sealing compound can. Have the
sealing compound exchanged by a specialised workshop.
● Seek professional assistance if the repair of a tyre puncture is not possi-
ble with the sealing product. Preparation work
Certain steps must be taken before repairing a tyre.
–
If you have a flat tyre or puncture, park the vehicle as far away
from the flow of traffic as possible.
– Apply the handbrake firmly.
– Engage first gear , or put the selector lever to position P.
– All occupants should leave the vehicle. They should wait in a
safe area (for instance behind the roadside crash barrier).
– Check whether a repair is possible using the Tyre Mobility Sys-
tem “General information and safety notes.”
– Unscrew inflation cap from the affected wheel.
– Take the tyre repair kit out of the luggage compartment.
WARNING
Put the hazard warning lights on and place the warning triangle in posi-
tion. This is for your own safety and also warns other road users.
CAUTION
Take special care if you have to repair a tyre on a slope.
