LPG tank in spare wheel well Before refuelling, turn off the engine and
switch off the ignition and mobile telephone
››› .
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

Checking and refilling levels
LPG quality and consumption
Quality requirements for LPG are regulated
for all Europe in DIN EN 589 and permit the
use of LPG throughout Europe.
A difference is drawn between winter gas and
summer gas. Winter gas has a higher propor-
tion of propane gas. As a result, the driving
range of winter gas may be lower (due to in-
creased consumption) than that of summer
gas.
LPG supplier network
The number of LPG pumps is constantly in-
creasing.
Lists of existing LPG pumps may be found on
Internet.
LPG safety A series of collision tests performed on this
vehicle while running with LPG have con-
firmed its high level of safety.
The safety of the LPG system guarantees op-
eration without risk. The following safety
measures have been adopted:
● The LPG tank has a solenoid valve which
closes automatically when the engine is
switched off (ignition off) or when running on
petrol. ●
A solenoid type main valve disconnects the
supply of gas to the engine compartment
when the engine is switched off or running
on petrol.
● A safety valve in the LPG tank with pipes to
the outside prevents the gas from entering
the vehicle interior.
● All anchorage points and materials have
been designed to ensure the maximum pos-
sible levels of safety.
The condition of the LPG system should be
checked regularly to guarantee safe driving
conditions ››› . These checks are included
in the Maintenance Programme. WARNING
● If there is a smell of gas or a suspected
leak, stop the vehicle immediately and switch
off the ignition. Open the doors to ventilate
the vehicle. Do not carry on driving! Take the
vehicle to a specialised workshop and have
the fault repaired.
● Immediately extinguish any cigarettes and
remove from the vehicle any objects which
might produce a spark or cause a fire, and
switch off immediately if gas is smelt or a
leak is detected.
● LPG tanks are subject to pressure and must
be checked regularly. The owner of the vehi-
cle must check that these services are per-
formed correctly. ●
When parking the vehicle in a closed area
(e.g. in a garage), make sure that there is ad-
equate ventilation, either natural or mechani-
cal, to neutralise the LPG in the event of a
leak. Note
For any fault in the LPG system, please refer
to the SEAT web page, which lists the work-
shops authorised to repair these faults. Working in the engine
compartment

Advice
You should not do any work in the engine
compartment unless you know exactly how to
carry out the jobs and have the correct tools!
Have the work carried out by a specialised
workshop if you are uncertain.
All service fluids and consumables, e.g. cool-
ant, engine oil, spark plugs and batteries,
are under constant development. SEAT pro-
vides a constant flow of information to Tech-
nical Services concerning modifications. For
this reason, we recommend you have service
fluids and consumables replaced by a Techni-
cal Service. Please observe the relevant in-
structions ››› page 147 . The engine compart-
ment of
the vehicle is a hazardous area.
››› .
WARNING
All work on the engine or in the engine com-
partment, e.g. checking and refilling fluids,
involves the danger of injury and burns, acci-
dents and even fire.
● Never open the bonnet if you see steam,
smoke or coolant escaping from the engine
compartment. Otherwise, there is a risk of
sustaining burns. Wait until no more steam or
coolant is emitted, then allow the engine to
cool before carefully opening the bonnet.
● Switch off the engine and remove the key
from the ignition.
● Apply the handbrake and move the gear
lever to neutral or selector lever to position P.
● Keep children away from the vehicle. ●
Never touch hot engine parts. There is a
risk of burns.
● Never spill liquids on a hot engine or on a
hot exhaust gas system. This is a fire hazard.
● Avoid causing short-circuits in the electri-
cal system, particularly at the points where
the jump leads are attached ››› page 190. The
battery could explode.
● Never touch the radiator fan. It is tempera-
ture controlled and could start automatically,
even when the engine has been switched off
and the key removed from the ignition!
● Never cover the engine with additional in-
sulating materials such as a blanket. Risk of
fire!
● Do not unscrew the cap on the coolant ex-
pansion tank when the engine is hot. If the
coolant is hot, the cooling system will be
pressurised!
● Protect face, hands and arms by covering
the cap with a large, thick cloth to protect
against escaping coolant and steam.
● Always make sure you have not left any ob-
jects, such as cleaning cloths or tools, in the
engine compartment.
● If you have to work underneath the vehicle,
you must use suitable stands additionally to
support the vehicle, there is a risk of acci-
dent!. A hydraulic jack is insufficient for se-
curing the vehicle and there is a risk of injury.
● If any work has to be performed when the
engine is started or with the engine running,
there is an additional, potentially fatal, safety
risk from the rotating parts, such as the drive belts, alternator, radiator fan, etc., and from
the high-voltage ignition system. You should
also observe the following:
– Never touch the electrical wiring of the
ignition system.
– Ensure that jewellery, loose clothing and
long hair do not get trapped in rotating
engine parts. Danger of death. Before
starting any work remove jewellery, tie
back and cover hair, and wear tight-fit-
ting clothes.
– Never accelerate with a gear engaged
without taking the necessary precau-
tions. The vehicle could move, even if the
handbrake is applied. Danger of death.
● If work has to be carried out on the fuel
system or on electrical components, you
must observe the following safety notes in
addition to the above warnings:
– Always disconnect the battery from the
on-board network. The vehicle must be
unlocked when this is done, otherwise
the alarm will be triggered.
– Do not smoke.
– Never work near naked flames.
– Always have a fire extinguisher on hand. CAUTION
When topping up service fluids, make sure
not to mistake them. Using the wrong fluids
could cause serious malfunctions and engine
damage! 164

Warnings on handling the battery Wear eye protection

Battery acid is extremely corrosive. Wear pro-
tective gloves and eye protection!

Fires, sparks, open flames and smoking are
prohibited!

A highly explosive mixture of gases is released
when the battery is under charge.

Keep children away from acid and batteries!
WARNING
Always be aware of the danger of injury and
chemical burns as well as the risk of accident
or fire when working on the battery and the
electrical system:
● Wear eye protection. Protect your eyes,
skin and clothing from acid and particles con-
taining lead. ●
Battery acid is extremely corrosive. Wear
protective gloves and eye protection. Do not
tilt the batteries. This could spill acid through
the vents. Rinse battery acid from eyes imme-
diately for several minutes with clear water.
Then seek medical care immediately. Neutral-
ise any acid splashes on the skin or clothing
with a soapy solution, and rinse off with plen-
ty of water. If acid is swallowed by mistake,
consult a doctor immediately.
● Fires, sparks, open flames and smoking are
prohibited. When handling cables and electri-
cal equipment, avoid causing sparks and
electrostatic charge. Never short the battery
terminals. High-energy sparks can cause in-
jury.
● A highly explosive mixture of gases is re-
leased when the battery is under charge. The
batteries should be charged in a well-ventila-
ted room only.
● Keep children away from acid and batteries.
● Before working on the electrical system,
you must switch off the engine, the ignition
and all electrical devices. The negative cable
on the battery must be disconnected. When a
light bulb is changed, you need only switch
off the light.
● Deactivate the anti-theft alarm by unlock-
ing the vehicle before you disconnect the bat-
tery! The alarm will otherwise be triggered.
● When disconnecting the battery from the
vehicle on-board network, disconnect first
the negative cable and then the positive ca-
ble. ●
Switch off all electrical devices before re-
connecting the battery. Reconnect first the
positive cable and then the negative cable.
Never reverse the polarity of the connections.
This could cause an electrical fire.
● Never charge a frozen battery, or one which
has thawed. This could result in explosions
and chemical burns. Always replace a battery
which has frozen. A flat battery can also
freeze at temperatures close to 0 °C (+32 °F).
● Ensure that the vent hose is always connec-
ted to the battery.
● Never use a defective battery. This could
cause an explosion. Replace a damaged bat-
tery immediately. CAUTION
● Never disconnect the battery if the ignition
is switched on or if the engine is running.
This could damage the electrical system or
electronic components.
● Do not expose the battery to direct sunlight
over a long period of time, as the intense ul-
traviolet radiation can damage the battery
housing.
● If the vehicle is left standing in cold condi-
tions for a long period, protect the battery
from “freezing”. If it freezes it will be dam-
aged. 173

●
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.

lead to the positive terminal + in the ve-
hicle providing assistance B .
4. For vehicles without Start-Stop system:
connect one end of the black jump lead to
the negative terminal – in the vehicle
providing assistance B
››› Fig. 163 .
– For

vehicles with Start-Stop system: Con-
nect one end of the black jump lead X to a
suitable ground terminal, a solid piece of
metal in the engine block, or to the engine
block itself ››› Fig. 164.
5. Connect the other end of the black jump
lead X to a solid metal component bolted
to the engine block or to the engine block
itself of the vehicle with the flat battery.
Do not connect it to a point near the bat-
tery A .
6. Position the leads in such a way that they cannot come into contact with any moving
parts in the engine compartment.
Starting
7. Start the vehicle's engine with the boost- ing battery and let it run at idling speed.
8. Start the engine of the vehicle with the flat battery and wait 2 or 3 minutes until the
engine is “running”. Removing the jump leads
9. Before you remove the jump leads, switch
off the dipped beam headlights (if they
are switched on).
10.Turn on the heater blower and heated rear window in the vehicle with the flat battery.
This helps minimise voltage peaks which
are generated when the leads are discon-
nected.
11. When the engine is running, disconnect
the l e
ads in reverse order to the details
given above.
Connect the battery clamps so they have
good metal-to-metal contact with the battery
terminals.
If the engine fails to start, switch off the start-
er after about 10 seconds and try again after
about a minute. WARNING
● Please note the safety warnings referring to
working in the engine compartment
››› page 163, Working in the engine compart-
ment.
● The b att

ery providing assistance must have
the same voltage as the flat battery (12 V)
and approximately the same capacity (see
imprint on battery). Failure to comply could
result in an explosion.
● Never use jump leads when one of the bat-
teries is frozen. Danger of explosion! Even 190

Emergencies
after the battery has thawed, battery acid
could leak and cause chemical burns. If a bat-
tery freezes, it should be replaced.
●
Keep sparks, flames and lighted cigarettes
away from batteries, danger of explosion.
Failure to comply could result in an explo-
sion.
● Observe the instructions provided by the
manufacturer of the jump leads.
● Do not connect the negative cable from the
other vehicle directly to the negative terminal
of the flat battery. The gas emitted from the
battery could be ignited by sparks. Danger of
explosion.
● Do not attach the negative cable from the
other vehicle to parts of the fuel system or to
the brake line.
● The non-insulated parts of the battery
clamps must not be allowed to touch. The
jump lead attached to the positive battery
terminal must not touch metal parts of the ve-
hicle, this can cause a short circuit.
● Position the leads in such a way that they
cannot come into contact with any moving
parts in the engine compartment.
● Do not lean on the batteries. This could re-
sult in chemical burns. Note
The vehicles must not touch each other, oth-
erwise electricity could flow as soon as the
positive terminals are connected. Towing and tow-starting
Tow-starting We recommend that you do
not tow-start your
v ehic
le. Jump-starting is preferable
››› page 189.
How

ever, if your vehicle has to be tow-
started:
– Engage 2 nd
or 3 rd
gear.
– Keep the clutch pressed down.
– Switch the ignition on.
– Once both vehicles are moving, release the
clutch.
– As soon as the engine starts, press the
clutch and move the gear lever into neutral.
This helps to prevent driving into the tow-
ing vehicle. WARNING
The risk of accidents is high when tow-start-
ing. The vehicle being towed can easily col-
lide with the towing vehicle. CAUTION
When tow-starting, fuel could enter the cata-
lytic converter and damage it. General notes
Please observe the following points if you
use a tow rope:
Notes for the driver of the towing vehicle
– Drive slowly at first until the tow rope is
taut. Then accelerate gradually.
– Begin and change gears cautiously. If you
are driving an automatic vehicle, accelerate
gently.
– Remember that the brake servo and power
steering are not working in the vehicle you
are towing. Brake sooner than normal and
pressing the pedal gently.
Notes for the driver of the towed vehicle
– Ensure that the tow rope remains taut at all
times when towing.
Tow rope or tow bar
It is easier and safer for the vehicle to be tow-
ed using a tow bar. You should only use a
tow-rope if you do not have a tow-bar.
A tow rope should be slightly elastic to re-
duce the loading on both vehicles. It is advis-
able to use a tow rope made of synthetic fi-
bre or similarly elastic material.
Attach the tow rope or the tow bar only to the
towline anchorages provided or a towing
bracket. »

Driving style
Towing requires some experience, especially
when using a tow rope. Both drivers should
be familiar with the technique required for
towing. Inexperienced drivers should not at-
tempt to tow.
Do not pull too hard with the towing vehicle
and take care to avoid jerking the tow rope.
When towing on an unpaved road, there is al-
ways a risk of overloading and damaging the
anchorage points.
The ignition of the vehicle being towed must
be switched on to prevent the steering wheel
from locking and also to allow the use of the
turn signals, horn, windscreen wipers and
washers.
The brake servo only works when the engine
is running. When not running, you must ap-
ply considerably more pressure to the brake
pedal.
As the power assisted steering does not work
if the engine is not running, you will need
more strength to steer than you normally
would.
● The vehicle must not be towed faster than
50 km/h (31 mph).
Towing vehicles with an automatic gearbox
● Put the selector lever into position “N”.
● Do not drive faster than 50 km/h (31 mph). ●
Do not tow further than 50 km.
● If a breakdown vehicle is used, the vehicle
must be towed with the front wheels raised. Note
● Observe legal requirements when towing or
tow-starting.
● Switch on the hazard warning lights of both
vehicles. However, observe any regulations
to the contrary.
● For technical reasons, vehicles with an au-
tomatic gearbox must not be tow-started.
● If there is no lubricant in the gearbox as the
result of a fault, you must raise the driven
wheels while the vehicle is being towed.
● If the vehicle has to be towed more than
50 km, the front wheels should be raised dur-
ing towing, and towing should be carried out
by a qualified person.
● The steering wheel is locked when the vehi-
cle has no electrical power. The vehicle must
then be towed with the front wheels raised.
Towing should be carried out by a qualified
person.
● The towline anchorage should always be
kept in the vehicle. Please refer to the notes
on ››› page 191, Tow-starting. Towline anchorages
