››› .
Read carefully the instructions on how to use
the LPG pump.
Opening the fuel tank cap
The LPG filler neck is behind the fuel cap,
next to the petrol filler neck.
● The tank flap is located on the rear right-
hand side of the vehicle.
● Open the fuel tank flap.
Refuelling
● Remove the plug from the gas filler mouth
››› Fig. 140 1 .
● Screw the required adapter 2 onto the
LPG gas filler neck. ●
Refuel as indicated in the pump instruc-
tions.
● The fuel tank will be full when the pump
c ompr
essor automatically cuts the supply.
● If you wish to finish refuelling sooner, re-
lease the button on the pump to stop the
flow.
Closing the fuel tank cap
● Unscrew the adapter from the gas filler
neck 2 .
● Screw the cap onto the gas filler neck 1 .
● Close the fuel tank flap. The cover should
be flush with the bodywork. WARNING
Incorrect handling of LPG can cause explo-
sions, fire, serious burns and other injuries.
● LPG is a highly explosive and inflammable
substance.
● Small quantities of LPG may leak out after
refuelling. If LPG comes into contact with the
skin there is a risk of freezing. Note
● The vehicle includes one adapter for the
country in question, the most common one.
We generally recommend that you carry all
the adapters in your vehicle, as some coun-
tries use more than one type of filling sys-
tem. ●
If the outside temperature is very high, the
protection against overheating for the LPG
pump may disconnect automatically.
● If the outside temperature is very high, the
pressure of the LPG tank may be equal to or
greater than that of the gas tank of the LPG
pump. In this case, refuelling will be physi-
cally impossible.
● The filling nozzles of LPG pumps can differ
in the way they are operated. If you do not
know, ask a qualified employee at the petrol
station to do the refuelling.
● Noises heard when refuelling are normal
and do not indicate the presence of a fault in
the system. 161

Wheels and tyres General notes Avoiding damage
– If you have to drive over a kerb or similar
obstacle, drive very slowly and at a right
angle.
– Keep grease, oil and fuel off the tyres.
– Inspect the tyres regularly for damage
(cuts, cracks or blisters, etc.). Remove any
foreign objects embedded in the treads.
Storing tyres
– When you remove the tyres, mark them in
order to maintain the same direction of ro-
tation when they are installed again.
– When removed, the wheels and/or tyres
should be stored in a cool, dry and prefera-
bly dark location.
– Store tyres in a vertical position if they are
not fitted on wheel rims.
New tyres
New tyres must be run in ›››
page 130.
The tread depth of new tyres may vary, ac-
cording to the type and make of tyre and the
tread pattern. Concealed damage
Damage to tyres and rims is often not readily
visible. If you notice unusual vibrations or the
vehicle pulling to one side, this may indicate
that one of the tyres is damaged. They
should be checked immediately by a Techni-
cal Service.
Tyres with directional tread pattern
An arrow on the tyre sidewall indicates the di-
rection of rotation on tyres with directional
tread. Always observe the direction of rota-
tion indicated when fitting the wheel. This
guarantees optimum grip and helps to avoid
aquaplaning, excessive noise and wear.
WARNING
● New tyres do not have maximum grip dur-
ing the first 500 km (300 miles). Drive partic-
ularly carefully to avoid possible accidents.
● Never drive with damaged tyres. This may
cause an accident.
● If you notice unusual vibrations or if the ve-
hicle pulls to one side when driving, stop the
vehicle immediately and check the tyres for
damage. Checking tyre pressure
The correct tyre pressure can be seen on the
sticker on the inside of the fuel tank flap.1. Read the required tyre inflation pressure
from the sticker. The values refer to Sum-
mer tyres. For winter tyres, you must add
0.2 bar (2.9 psi / 20 kPa) to the values
given for summer tyres.
2. The tyre pressures should only be checked when the tyres are cold. The slightly raised
pressures of warm tyres must not be re-
duced.
3. Adjust the tyre pressure to the load you are carrying.
Tyre pressure
The correct tyre pressure is especially impor-
tant at high speeds. The pressure should
therefore be checked at least once a month
and before starting a journey.
The sticker with the tyre pressure values can
be found on the inside of the fuel tank flap.
The tyre pressure values given are for cold
tyres. Do not reduce the slightly raised pres-
sures of warm tyres ››› .
WARNING
● Check the tyre pressure at least once per
month. Checking the tyre pressure is very im-
portant. If the tyre pressure is too high or too
low, there is an increased danger of accidents
- particularly at high speeds.
● A tyre can easily burst if the pressure is too
low, causing an accident! » 175Technical specifications
Advice
Operation
Safety

Advice
●
At continuously high speeds, a tyre with in-
sufficient pressure flexes more. In this way it
becomes too hot, and this can cause tread
separation and tyre blow-out. Always observe
the recommended tyre pressures.
● If the tyre pressure is too low or too high,
the tyres will wear prematurely and the vehi-
cle will not handle well. Risk of accident! For the sake of the environment
Under-inflated tyres will increase fuel con-
sumption. Tyre pressure monitoring
The tyre pressure monitoring system con-
stantly checks the pressure of the tyres.
The system uses the speed sensors of the
ABS wheels. It operates by analysing the
speed and frequency spectrum of each
wheel.
For optimum performance, use genuine SEAT
tyres. In addition, check and adjust tyre pres-
sures regularly.
Whenever the tyre pressure is are changed or
one or more tyres are changed, the system
should be reset by pressing the SET button
on the centre console.
The system warns the driver in the event of a
loss of pressure by means of symbols and messages in the instrument panel display.
The system operates via the ESC
››› page 134.
Note that tyre pressure also depends on tyre
temperature. Said pressure increases around
0.1 bar (2.9 psi/10 kPa) for each +10 °C
(+50 °F) in tyre temperature increase. The tyre
heats up while the vehicle is being driven
and the tyre pressure will rise accordingly.
Therefore, you should only adjust the tyre
pressure when they are cold (i.e. approxi-
mately at ambient temperature).
To ensure that the tyre pressure monitoring
system works reliably, you should check and,
if necessary, adjust the tyre pressures at reg-
ular intervals and store the correct pressures
(reference values) in the system.
A tyre pressure information label is attached
to the inside of the fuel tank flap. WARNING
● Never adjust tyre pressure when the tyres
are hot. This may damage or even burst the
tyres. Risk of accident!
● An insufficiently inflated tyre flexes a lot
more at high speeds and causes significant
heating of the tyre. 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 lead to increased fuel
consumption and tyre wear. Significant tyre pressure loss
The tyre symbol
 is displayed and indicates
th at
the tyre pressure of at least one tyre is
insufficient.
– Stop the vehicle.
– Switch the ignition off.
– Check the tyre(s).
– Change the wheel if necessary.

Wheels
Tyre useful life Fig. 152
Tyre tread wear indicators. Fig. 153
Diagram for changing wheels The useful life of tyres is dependent on tyre
pressure, driving style and fitting.
Wear indicators
The original tyres on your vehicle have
1.6 mm high “tread wear indicators”
››› Fig. 152 , running across the tread. De- pendin
g on the m ake, there will be 6 to 8 of
them evenly spaced around the tyre. Mark-
ings on the tyre sidewall (for instance the let-
ters “TWI” or other symbols) indicate the po-
sitions of the tread wear indicators. The mini-
mum tread depth required by law is 1.6 mm
(measured in the tread grooves next to the
tread wear indicators). Worn tyres must be re-
placed. 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 175.
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 advisable to change
them around as shown ››› Fig. 153 . The use-
f u

l life of all the tyres will then be about the
same time.
Wheel balance
The wheels on new vehicles are balanced.
However, various factors encountered in nor-
mal driving can cause them to become unbal-
anced, which results in steering vibration. Unbalanced wheels should be rebalanced, as
they otherwise cause excessive wear on
steering, suspension and tyres. A wheel must
also be rebalanced 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 Tech-
nical 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 indicators are worn
››› page 177. Failure to follow this instruction
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 in-
sufficient 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 pressures.
● 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 re-
placed immediately! » 177

Advice
For the sake of the environment
Under-inflated tyres will increase fuel con-
sumption. 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 137.
– Continue driving carefully and slowly
(80 km/h [50 mph] maximum).
– Avoid sudden manoeuvres and sharp turns.
– Avoid driving over obstacles (e.g. kerbs) or
potholes.
– Pay attention if the ESC/ASR activates of-
ten, 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 vehicle. The run-flat tyres have a tag on the side of
the tyre, with the description: “DSST”, “Eufo-
nia”, “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 cir-
cumstances are favourable (e.g. 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 replace it if necessary. We rec-
ommend you contact your technical service.
If more than one tyre is being used under
emergency conditions, this reduces the dis-
tance that 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 condi-
tions
››› .
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 dam-
aged 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 dam-
age 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 over-
heating and gives off smoke. WARNING
When driving in emergency conditions, the
driving quality of the vehicle is considerably
impaired.
● The maximum permitted speed of 80 km/h
(50 mph) is subject to road and weather con-
ditions. Please observe related legal require-
ments.
● Avoid sharp turns and rapid manoeuvres,
and brake earlier than usual.
● Avoid driving over obstacles (e.g. kerbs) or
potholes.

Advice
For the sake of the environment
Old tyres must be disposed of according to
the laws in the country concerned. Note
● For technical reasons, it is not generally
possible to use the wheels from other vehi-
cles. 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 vehi-
cle'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 period 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
›››
page 147. 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 loosen whilst the vehi-
cle is in motion. Risk of accident! If the tight-
ening torque 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 service
Winter tyres In winter conditions winter tyres will consid-
erably improve the vehicle's handling. Sum-mer tyres (width, rubber compound, tread
pattern) provide less grip on ice and snow.
Winter tyres must be inflated to a
pressure of
0.2 bar (2.9 psi/20 kPa) higher than the pres-
sures 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 registration
documentation. Use only radial winter tyres.
All tyre sizes listed in the vehicle documenta-
tion also apply to winter tyres.
Winter tyres lose their effectiveness when the
tread is worn down to a depth of 4 mm.
The speed rating code ››› page 179, New
tyres and wheels determines the following
speed limits for winter tyres:
›
› › max. 160 km/h
max. 180 km/h
max. 190 km/h
max. 210 km/h
In some countries, vehicles which can exceed
the speed rating of the fitted tyre must have
an appropriate sticker in the driver's field of
view. These stickers are available from your
technical service. The legal requirements of
each country must be followed.
Do not have winter tyres fitted for unnecessa-
rily long periods. Vehicles with summer tyres Q

Advice
●
Never start the engine when the vehicle is
on the jack. Risk of accident.
● If work is to be carried out underneath the
vehicle, this must be secured by suitable
stands. Otherwise, there is a risk of injury. Note
The jack does not generally require any main-
tenance. If required, it should be greased us-
ing universal-type grease. Compact spare wheel* (temporary
spare wheel)
Fig. 154
Luggage compartment. Accessing
the spare wheel. The compact spare wheel (temporary spare
wheel for vehicles without the anti-puncture
kit) should only be used when strictly neces-
sary. The temporary spare wheel is stored under
the floor panel in the luggage compartment
and is attached by a thumbnut.
How to use the temporary spare wheel
Should you ever have a punctured tyre, the
compact temporary spare wheel is only inten-
ded 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 tem-
porary spare wheel has been specially de-
signed for your vehicle, thus, it cannot be re-
placed by a temporary spare wheel from an-
other vehicle.
No other type of tyre (normal summer or win-
ter tyre) may be fitted on the compact tempo-
rary spare wheel rim.
Snow chains
For technical reasons, snow chains must
not
be used on the compact temporary spare
wheel.
If you have a puncture on one of the front
wheels when using snow chains, fit the com-
p act
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 possible after fitting the
temporary spare wheel. The pressure of the
spare wheel sized 125/70R16 125/70R18
135/90R16 should be 4.2 bar
(61 psi/420 kPa). For other sizes, check the
label on the fuel cap. Failure to follow this in-
struction could result in an accident.
● Do not drive faster than 80 km/h (50 mph),
since higher speeds can cause an accident.
● Avoid heavy acceleration, hard braking and
fast cornering. Risk of accident.
● 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. Wheel change
Preparation work –
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 ve-
hicle. They should wait in a safe area (for
instance behind the roadside crash barri-
er).
