Trip recorder
Fig. 40 Instrument pan-
el: Odometer and reset
button
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

⇒  Fig. 40.
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. 

Driver assistance systems
For the sake of the environment
Under-inflated tyres lead to increased fuel consumption and tyre wear.
Note
● Driving for the first time with new tyres at a high speed can cause them
to slightly expand, which could then produce an air pressure warning.
● Only replace used tyres with those authorised by SEAT for the corre-
sponding type vehicle.
● Do not only rely on the tyre monitoring system. Regularly check your
tyres to ensure that the tyre pressure is correct and that the tyres are not
damaged due to puncture, cuts, tears and impacts/dents. Remove objects
from the tyres only when they have not pierced the tyres. 
Tyre monitor indicator warning lamp
lights upPossible causeSolution

The pressure in one or more
tyres has clearly reduced in
comparison to the tyre pres-
sure set by the driver or the
tyre has structural damage.
Additionally, an audible warn-
ing can be heard and a text
message can be seen on the
instrument panel display. Stop the vehicle! Reduce
speed immediately! Stop the
vehicle safely as soon as pos-
sible. Avoid sudden manoeu-
vres and braking! Check all
tyres and pressures. Replace
any damaged tyres.
flashesPossible causeSolution

System malfunction. The con-
trol lamp flashes for about one
minute and then lights up per-
manently.
If the tyre pressure is correct,
switch the ignition off and on
again. If the control lamp re-
mains lit up, the tyre monitor-
ing indicator can be calibra-
ted. Have the system reviewed
by a specialised workshop.
Several warning and control lamps light up for a few seconds when the igni-
tion is switched on while the function is verified. They will switch off after a
few seconds.
WARNING
When the tyres are inflated at different pressures or at a pressure that is
too low then a tyre may be damaged resulting in a loss of control of the
vehicle and a serious or fatal accident.
● If the warning lamp  lights up, stop immediately and check the
tyres.
● If the tyres are inflated at different pressures or if a tyre pressure is
too low, this will increase tyre wear, negatively affecting vehicle stability
and increasing braking distances.
● If tyres are inflated at different pressures or a tyre pressure is too low,
a tyre may be damaged and burst resulting in a loss of control of the ve-
hicle.
● The driver is responsible for ensuring that all of the vehicle tyres are
correctly inflated to the right pressure. The recommended tyre pressure
is indicated on the label ⇒ page 307.
● The tyre monitoring system can only operate correctly if all of the
tyres are inflated to the correct pressure when cold. 

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. 

247
Checking and refilling levels
● Only use fuel additives that have been approved by SEAT. Octane boost-
ing or anti-knock additives may contain metal additives that could seriously
damage the engine or the catalytic converter. These additives must not be
used.
● High engine speed and full throttle can damage the engine when using
petrol with an octane rating lower than the correct grade for the engine.
Note
● You may use petrol with a high octane number than the one recommen-
ded for your engine.
● In those countries where unleaded petrol is not available, you may refuel
with a fuel with a low lead content. 
Diesel Fuel
Please note the information on the inside of the fuel tank
flap.
We recommend the use of Diesel fuel which complies to European standard
EN 590. If diesel fuel which meets European standard EN 590 is not availa-
ble, the Cetane number (CZ) must, at minimum, be 51. If the engine is
equipped with a particulate filter, the sulphur content of the fuel must be
below 50 parts per million.
Winter-grade diesel
Summer fuel becomes thicker in winter and it is more difficult to start the
engine. For this reason petrol stations in some countries also offer winter
diesel with improved fluidity when cold.
CAUTION
● The vehicle is not designed for the use of biodiesel (FAME fuel). The fuel
system would be damaged if you used biodiesel.
● Do not mix fuel additives, the so-called “thinners”, petrol or similar ad-
ditives with diesel fuel.
● If poor-quality diesel fuel is used, it may be necessary to drain the fuel
filter more frequently than is specified in the Service Plan. We recommend
having this done by a specialised workshop. If water is allowed to collect in
the filter, this can cause engine performance problems. 
Natural gas
Natural gas
Natural gas, in addition to others, can be in compressed or liquid form.
Liquefied natural gas (LNG) is the result of heavy cooling of natural gas.
Therefore its volume is considerably reduced compared with compressed
natural gas (CNG). In vehicles with a natural gas engine, liquefied natural
gas cannot be directly refilled, given that the gas would expand excessively
in the vehicle gas tank.
Therefore, vehicles with a natural gas engine must only be refuelled using
compressed natural gas ⇒ 
.
Natural gas quality and consumption
Natural gas is divided into the groups H and L depending on its quality.
Gas type H has a superior heating power and inferior nitrogen and carbon
dioxide content than type L. The higher the heating power of the natural
gas, the lower the consumption will be.
However, the heating power and the proportion of nitrogen and carbon di-
oxide can fluctuate within the quality groups. Therefore, vehicle consump-
tion can also vary, even when using one type of gas only. 

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

Before refuelling, the engine and the ignition, mobile telephone and heat-
ing must be switched off separately
⇒ .
Read the instructions on how to use the natural gas pump carefully.
The vehicle is not prepared for refuelling with liquefied natural gas (LNG)
⇒ 
. Before refuelling with natural gas, make sure to add the appropriate
type of fuel ⇒ page 246.
Opening the fuel tank cap
The natural gas filler mouth is behind the fuel tank cap, next to the petrol
filler mouth.
● Unlock the vehicle with the key or with the central locking button 
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. 
