Manual switch from petrol to LPG
Press the GAS button to switch modes. When the necessary conditions are
met, the system switches to LPG mode and the ON lamp is lit. If the ON
lamp flashes, the following conditions have not been met:•There is enough LPG in the tank.•The temperature of the vehicle coolant is above 30°C.•Engine speed while driving is above 1200 rpm.
When these conditions are met, the system switches to LPG mode and the ON
lamp is lit .
Manual switch from LPG to petrol
Press the button to switch modes. When the OFF lamp is lit, the
vehicle is running on petrol.
Running on petrol
Run the engine with petrol for short journeys at regular intervals to avoid
problems in the petrol system.WARNING
LPG is a highly explosive and inflammable substance. It may cause severe
burns and other injury.•Due care must be taken to avoid any risk of fire or explosion.•When parking the vehicle in a closed area (for example in a garage),
make sure that there is adequate ventilation, either natural or mechanical,
to neutralise the LPG in the event of a leak.
Note
•If frequent short journeys are made, especially when the outside temper-
ature is low, the vehicle will tend to run on petrol more often than on LPG.
Therefore, the petrol tank may empty before the LPG tank.Start-Stop function*Description and operationThe Start-Stop function stops the engine when the vehicle is
stopped and starts it automatically when required.

Segments in the optical display
Som e colour segments in front and behin d and an acoustic signal enable the
driver to assess the distance with respect to an obstacle. The amber colour
segments combined with a discontinuous beep indicate the presence of an
obstacle. As the vehicle gets closer to the obstacle, the colour of the segment
changes to red and the acoustic signal beeps continuously. When the penul-
timate segment is displayed, this means that the vehicle has reached the
collision zone. Stop moving immediately! ⇒
WARNING
•The parking aid is not a replacement for driver awareness. The driver is
personally responsible for safe parking and other manoeuvres.•The sensors have blind spots in which obstacles are not registered.
Always look out for small children and animals because the system will not
always detect them. Always pay attention when reversing to avoid acci-
dents.•Always keep a close eye on the area around the vehicle and make full
use of the rear-view mirrors.Caution
Please note that low obstacles detected by the system may no longer be
registered by the sensors as the car moves closer, so the system will not give
any further warning. Certain kinds of obstacles (such as wire fences, chains,
thin painted posts or trailer draw bars, etc) may not always be detected by the
system, so take care not to damage the vehicle in such cases.
Note
•Please refer to the notes on towing ⇒page 187.•There is a slight delay in the picture display.To w i n g b r a c k e tIn towing mode, the rear parking sensors are not enabled when you select
reverse gear or press the switch
. This function may not be guaranteed on
towing brackets that are not factory fitted. This results in the following restric-
tions:

No warning is given.
SEAT Parking System Plus*
There is no rear distance warning. The system will still give a warning when
obstacles are detected while driving forwards. The optical display changes to
towing mode.
Fault messagesIf you hear a long beep for a few seconds and the LED on the switch
* starts
flashing when you switch on the parking aid, a system fault has occurred.

Checking and refilling levels
230•Wait until no more steam, smoke or coolant is emitted from the bonnet,
then carefully open the bonnet.•When working in the engine compartment, always observe the safety
warnings ⇒page 227.
Closing the bonnet– Raise the bonnet slightly.
– Release the bonnet stay and replace it in its support.
– At a height of about 30 cm let it fall so it is locked.If the b onn et d o es n ot clos e , do not p ress d ownwa rds . Op e n it o nce m or e an d
let it fall as before.
WARNING
If the bonnet is not closed properly, it could open while you are driving and
completely obscure your view of the road. Risk of accident.•After closing the bonnet, always check that it is properly secured. The
bonnet must be flush with the surrounding body panels.•If you notice that the bonnet latch is not secured when the vehicle is
moving, stop the vehicle immediately and close the bonnet properly. Risk
of accident.
Engine oilEngine oil specifications
The engine oil used must conf orm with exact specifications.Specifications
The engine comes with a special, high quality, multi grade oil that can be
used in all seasons of the year except for those regions affected by extreme
cold.
As the use of high quality oil is essential for the correct operation of the
engine and its long useful life, when topping up or replacement is necessary
use only those oils that conform to the requirements of the VW standards.
If it is not possible to find oil conforming to the VW standards then oil
conforming to the ACEA or API standards with an appropriate viscosity at
atmospheric temperature should be used instead. The use of this type of oil
may have some repercussions on the performance of the engine for example,
long starting time, increased consumption and a higher emission level.
If a top up is required then different oils may be mixed as long as they all
conform to the VW standards.
The specifications (VW standards) set out in the following page should
appear on the container of the service oil; the container will display together
the different standards for petrol and diesel engines, the oil can be used for
both types of engines.

Checking and refilling levels
240Brake fluidChecking the brake fluid level
The brake fluid is checked at the intervals given in the service
schedule.– Read off the fluid level at the transparent brake fluid reservoir. It
should always be between the “MIN” and “MAX” marks.The position of the brake fluid reservoir is shown in the corresponding engine
compartment diagram ⇒page 287. The brake fluid reservoir has a black and
yellow cap.
The brake fluid level drops slightly when the vehicle is being used as the
brake pads are automatically adjusted as they wear. However, if the level goes down noticeably in a short time, or drops below the
“MIN” mark, there may be a leak in the brake system. A display on the instru-
ment panel will warn you if the brake fluid level is too low
⇒page 77.
WARNING
Before opening the bonnet to check the brake fluid level, read and observe
the warnings ⇒page 227.Changing the brake fluid
The Maintenance Program indicates the brake fluid change
intervals.We recommend that you have the brake fluid changed by an Authorised
Service Centre.
Before opening the bonnet, please read and follow the warnings ⇒ in
“Safety instructions on working in the engine compartment” on page 227 in
“Working in the engine compartment”.
Brake fluid absorbs moisture. In the course of time, it will absorb water from
the ambient air. If the water content in the brake fluid is too high, the brake
system could corrode. This also considerably reduces the boiling point of the
brake fluid. Heavy use of the brakes may then cause a vapour lock which
could impair the braking effect.
It is important that you use only brake fluid compliant with the US standard
FMVSS 116 DOT 4. We recommend the use of Genuine SEAT brake fluid.
WARNING
Brake fluid is poisonous. Old brake fluid impairs the braking effect.

242charge. Never short the battery terminals. High-energy sparks can cause
injury.•A highly explosive mixture of gases is released when the battery is
under charge. The batteries should be charged in a well-ventilated 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 consumers. 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 unlocking the vehicle before you
disconnect the battery! The alarm will otherwise be triggered.•When disconnecting the battery from the vehicle electrical system,
disconnect first the negative cable and then the positive cable.•Switch off all electrical consumers before reconnecting 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 freeze at temperatures around 0°.•Ensure that the vent hose is always connected to the battery.•Never use a defective battery. This may be fatally explosive. Replace a
damaged battery 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 compo-
nents.•Do not expose the battery to direct sunlight over a long period of time, as
the intense ultraviolet radiation can damage the battery housing.
•If the vehicle is left standing in cold conditions for a long period, protect
the battery from frost. If it “freezes” it will be damaged.Checking the electrolyte level
The electrolyte level should be checked regularly in high-
mileage vehicles, in hot countries and in older batteries.– Open the bonnet and open the battery cover at the front ⇒ in
“Safety instructions on working in the engine compartment” on
page 227 ⇒ in “Warnings on handling the battery” on
page 241.
– Check the colour display in the "magic eye" on the top of the battery.
– If there are air bubbles in the window, tap the window gently until they disperse.The position of the battery is shown in the corresponding engine compart-
ment diagram ⇒page 287.
The “magic eye” indicator, located on the top of the battery changes colour,
depending on the charge state and electrolyte level of the battery.
There are two different colours:•Black: correct charge status.•Transparent/clear yellow: the battery must be replaced. Contact a
specialist workshop.

2. The tyre pressures should only be checked when the tyres are
cold. The slightly raised pressures of warm tyres must not be
reduced.
3. Adjust the tyre pressure to the load you are carrying.Tyre pressure
The correct tyre pressure is especially important 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
tank flap. The tyre pressure values given are for cold tyres. The slightly raised
pressures of warm tyres must not be reduced ⇒.
WARNING
•Check the tyre pressure at least once per month. Checking tyre pressure
value is very important. 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!•At continuously high speeds, a tyre with insufficient 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 prema-
turely and the vehicle will not handle well. Risk of accident!For the sake of the environment
Under-inflated tyres will increase fuel consumption.
Tyre pressure monitoring
The tyre pressure monitoring system constantly 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 pressures regularly.
Whenever the tyre pressures are changed or one or more tyres are changed,
the system should be Reset by pressing the SET switch on the central console.
The system warns the driver in the event of a loss of pressure by means of
symbols and messages in the instrument cluster display. The system uses
ESP ⇒page 195.
Note that tyre pressure also depends on tyre temperature. Tyre pressure
increases about 0.1 bar for each 10C in tyre temperature increase. The tyre
heats up while the vehicle is being driven and the tyre pressure will rise
accordingly. For this reason, you should only adjust the tyre pressures when
they are cold (i.e. approximately at ambient temperature).
To ensure that the tyre pressure monitoring system works reliably, you should
check and, if necessary, adjust the tyre pressures at regular intervals and
store the correct pressures (reference values) in the system.

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!

Driving with anti-puncture tyres (emergency gear)
– Leave the ESP/TCS (electronic stabilisation programme) switched on, or switch on ⇒page 195.
– Continue driving carefully and slowly (80 km/h maximum).
– Avoid sudden manoeuvres and sharp turns.
– Avoid driving over obstacles (for example kerbs) or potholes.
– Look out for the ESP/TCS intervening often, smoke coming from the tyres or the smell of rubber, the vehicle vibrating or a clat-
tering noise. If any of these occur, stop the vehicle.The anti-puncture 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 and if the circumstances are favourable (for
example, low load), even more.
The damaged tyre should be changed as soon as possible. The rim should be
checked in a specialist workshop to detect possible damage and replace it if
necessary. We recommend you contact Technical Service. If more than one
tyre is being used under emergency co nditions, this reduces the distance
which can be travelled.
Starting driving in emergency conditions
When the loss in tyre pressure is displayed on the instrument panel, this
implies 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 anti-puncture
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.WARNING
When driving in emergency conditions, the driving quality of the vehicle is
considerably impaired.•The maximum permitted speed of 80 km/h is subject to road and
weather conditions. Please observe legal requirements when doing so.•Avoid sharp turns and rapid manoeuvres, and brake earlier than usual.•Avoid driving over obstacles (for example kerbs) or potholes.•If one or more tyres is being driven in emergency conditions, the driving
quality of the vehicle is impaired and there is a risk of accident.Note
•The anti-puncture tyres do not “deflate” on losing pressure because they
are supported on the reinforced sides. Therefore defects in the tyre can not be
detected with a visual inspection.•Snow chains must not be used on front tyres used in emergency
conditions.
