The distance covered is displayed in “kilometres” or miles “m”. It is possi-
ble to change the measurement units (kilometres “km”/miles “m”) in the
radio/Easy Connect*. Please refer to the Easy Connect* Instruction Manual
for more details.
Odometer/trip recorder
The odometer shows the total distance covered by the vehicle.
The trip recorder shows the distance that has been travelled since it was
last reset. It is used to measure short trips. The last digit of the trip recorder
indicates distances of 100 metres or tenths of a mile.
The trip recorder can be set to zero by pressing 0.0/SET

Fault display
If there is a fault in the instrument panel, the letters DEF will appear in the
trip recorder display. Have the fault repaired immediately, as far as is possi-
ble. Fuel level
The display
6 ⇒ Fig. 38 only works when the ignition is switched on. When
the display reaches the reserve mark, the lower diode lights up in red and
the control lamp  appears ⇒ page 248. When the fuel level is very low,
the lower diode flashes in red.
The distance to empty fuel level is displayed on the instrument panel 3
⇒ Fig. 38.
The capacity of the fuel tank of your vehicle is given in the Technical data
section ⇒ page 323.
In natural gas engines
The yellow warning lamp
 lights up when both fuel types (petrol and natu-
ral gas) have reached reserve level.
The green control lamp  comes on when the vehicle is working with natural
gas.
The green control lamp  switches off when the natural gas is exhausted.
The engine changes to operate with petrol.
Thing to note: If the vehicle is left parked for a long time immediately after
refuelling, the natural gas level indicator may not accurately indicate the
same level shown after refuelling when the vehicle is started up again. This
is not due to a leak in the system, but to a drop in pressure in the gas tank
for technical reasons after a cooling phase immediately after refuelling.
CAUTION
Never run the fuel tank completely dry. An irregular fuel supply could cause
misfiring. In this way the unburned fuel can reach the exhaust system,
which could cause the catalytic converter to overheat resulting in damage. 

Windscreen wiper functions
Windscreen wiper performance in different situations:If the vehicle is at a stand-
still:The activated position provisionally changes
to the previous position.
During the automatic wipe:
The air conditioner comes on for approxi-
mately 30 seconds in air recirculation mode
to prevent the smell of the windscreen wash-
er fluid entering the inside the vehicle.
For the interval wipe:The intervals between wipes vary according
to the speed of the vehicle. The higher the
vehicle speed the shorter the intervals.
Heated windscreen washer jets
The heating only thaws the frozen jets, it does not thaw the water in the
washer hoses. The heated windscreen washer jets automatically adjust the
heat depending on the ambient temperature, when the ignition is switched
on.
Headlight wash/wipe system
The headlight washers/wipers clean the headlight lenses.
After the ignition is switched on, the first and every fifth time the wind-
screen washer is switched on, the headlights are also washed. Therefore,
the windscreen wiper lever should be pulled towards the steering wheel
when the dipped beam or main beam are on. Any incrusted dirt (such as in-
sects) should be cleaned regularly (e.g. when refuelling).
To ensure the headlight washers work correctly in winter, any snow which
has got into the bumper jet supports should be cleaned away. If necessary,
remove snow with an anti-icing spray.
Note
The wiper will try to wipe away any obstacles that are on the windscreen.
The wiper will stop moving if the obstacle blocks its path. Remove the ob-
stacle and switch the wiper back on again. 
Windscreen wipers service position

Fuel
Types of petrol
The correct grade of petrol is listed inside the fuel tank flap.
The vehicle is equipped with a catalytic converter and must only be run on
unleaded petrol. The petrol must comply with European Standard EN 228 or
German standard DIN 51626-1 and must be unleaded. You can refuel with a
maximum ethanol proportion of 10 % (E10). The types of petrol are differen-
tiated by their octane rating (RON).
The following titles appear on the corresponding adhesive on the fuel tank
flap:
Super unleaded 95 octane or normal 91 octane unleaded petrol
We recommend you use super 95 octane petrol. If this is not available: nor-
mal 91 octane petrol, with a slight decrease in power.
Super unleaded petrol with a minimum of 95 octanes
You should use super petrol with a minimum of 95 octanes.
If super is not available, in an emergency you may refuel with normal 91 oc-
tane petrol. In this case only use moderate engine speeds and a light throt-
tle. Refuel with super as soon as possible.
Super unleaded 98 octane or super 95 octane unleaded petrol
We recommend you use super plus 98 octane petrol. If this is not available:
super 95 octane petrol, with a slight decrease in power.
If super is not available, in an emergency you may refuel with normal 91 oc-
tane petrol. In this case only use moderate engine speeds and a light throt-
tle. Refuel with super as soon as possible. Petrol additives
The quality of the fuel influences the behaviour, performance and service
life of the engine. This is why the petrol you use should carry suitable addi-
tives already included by the petrol industry, free of metals. These additives
will help to prevent corrosion, keep the fuel system clean and prevent de-
posits from building up in the engine.
If good quality petrol with metal-free additives is not available or engine
problems arise, the necessary additives must be added when refuelling
⇒ 
.
Not all petrol additives have been shown to be effective. The use of unsuita-
ble petrol additives may cause significant damage to the engine and the
catalytic converter. Metal additives should never be used. Metal additives
may also be contained in petrol additives for improving anti-detonation rat-
ings or octane ratings ⇒ 
.
SEAT recommends “Genuine Volkswagen Group fuel additives for petrol en-
gines”. These additives can be bought at SEAT Authorised Services, where
information on how to use them can also be obtained.
CAUTION
● Do not refuel if the filler indicates that the fuel contains metal. LRP (lead
replacement petrol) fuels contain high concentrations of metal additives.
Using them may damage the engine!
● Never refuel with fuels containing a large proportion of ethanol (for ex-
ample, E50, E85). This could damage the fuel system.
● Just filling one full tank of leaded fuel or fuel containing other metal ad-
ditives would seriously impair the efficiency of the catalytic converter. 

248Checking and refilling levels
The engine management automatically adapts to the natural gas used ac-
cording to its quality. Therefore, different quality gases can be mixed in the
tank, without the need for comprehensive draining before applying a differ-
ent quality gas.
The instrument panel display shows information on the current natural gas
quality ⇒ page 73.
Natural gas and safety
If you can smell gas or suspect that there is a leak ⇒ 
:
● Stop the vehicle immediately.
● Switch the ignition off.
● Open the doors to appropriately ventilate the vehicle.
● Extinguish cigarettes immediately.
● Move away from the vehicle or switch off objects that may cause sparks
or a fire.
● If you continue to smell gas, do not continue driving!
● Seek specialist assistance. Have the fault repaired.
WARNING
Failure to act when you can smell gas in the vehicle or when refuelling
can cause serious injuries.
● Carry out the necessary operations.
● Leave the danger zone.
● If necessary, warn the emergency services.
WARNING
The vehicle is not prepared to use liquefied natural gas (LNG) and this
fuel must not be added under any circumstances. Liquefied natural gas
can cause the natural gas tank to explode resulting in serious injury.
Note
Have natural gas system checked regularly by a specialised workshop in ac-
cordance with the Maintenance Programme. 
Filling the tank Filling the tank
Fig. 151 Fuel tank flap
with tank cap attached
The flap that covers the tank cap is unlocked and locked automati-
cally by the central locking.
Opening the fuel tank cap
– Open the fuel tank flap, by pressing on the left side.
– Unscrew the fuel tank cap anti-clockwise. 

250Checking and refilling levels
For the sake of the environment
Do not overfill the fuel tank – it may cause the fuel to overflow if it becomes
warm.
Note
Diesel vehicles are fitted with a protective device that prevents the insertion
of the wrong fuel hose 1)
. It is only possible to refuel with Diesel nozzles.
● If the pump nozzle is worn, damaged, or if it is very small, it is possible
that it will not be able to open the protective device. Before trying to insert
the pump nozzle by turning it, try a different pump or request specialist
help.
● If you fill the tank from a reserve fuel canister, the protective device will
not open. One way to resolve this is to pour the fuel in very slowly. 
Refuelling natural gas

situ-
ated on the driver door ⇒ page 87.
● Press on the rear area of the flap and open it.
Refuelling
Thing to note: if the ambient temperature is very high, the natural gas pump
protection against overheating may disconnect this automatically.
● Remove the plug from the gas filler mouth ⇒ Fig. 152 1
.
● Connect the pump filling nozzle to the gas filler mouth.
● The fuel tank will be full when the pump compressor automatically cuts
the supply.
● If you wish to finish refuelling in advance, press the button on the pump
to stop the flow.
Closing the fuel tank cap
● Check that the gas filler mouth retainer 2
is not trapped with the filler
nozzle. If necessary, place it in the filler mouth again.
● Insert the plug in the filler mouth.
● Close the tank flap. Make sure you hear it click into place. 

Checking and refilling levels
WARNING
Natural gas is a highly explosive, easily flammable substance. Incorrect
handling of the natural gas can cause accidents serious burns and other
injuries.
● Before refuelling with natural gas, engage the filler neck correctly. If
you smell gas, stop refuelling immediately.
WARNING
The vehicle is not prepared to use liquefied natural gas (LNG) and this
fuel must not be added under any circumstances. Liquefied natural gas
can cause the natural gas tank to explode resulting in serious injury.
Note
● The filling nozzles of all natural gas pumps might not be operated in the
same way. 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 pres-
ence of damage to the system.
● The vehicle natural gas system is prepared both for refuelling with a
small compressor (slow refuel) and a large compressor (fast refuel) in natu-
ral gas service stations. Bonnet
Working on components in the engine compartment
Extra caution is necessary when working on components in
the engine compartment. Always be aware of the danger of injury and scalding as well as the risk of
accident or even fire when working in the engine compartment (e.g. when
checking and refilling fluids). Always observe the warnings listed below
and follow all general safety precautions. The engine compartment of the
vehicle is a potentially hazardous area ⇒ 
.
WARNING
● Switch the ignition off.
● Remove the ignition key.
● Apply the handbrake.
● If the vehicle has a manual gearbox, place the lever in neutral; if it
has an automatic gearbox, place the selector lever in position P.
● Wait for the engine to cool down.
● Keep children away from the engine compartment.
● Never spill liquids used for vehicle operation on the engine compart-
ment, as these may catch fire (e.g. the antifreeze in coolant).
● Take care not to cause short circuits in the electrical system, especial-
ly when working on the battery.
● If working inside the engine compartment, remember that, even when
the ignition is switched off, the radiator fan may start up automatically,
and therefore there is a risk of injury.
● Do not unscrew the cap on the coolant expansion tank when the en-
gine is hot. The cooling system is under pressure. 
