146Starting, changing gears, parking
Unnecessary short journeys should be avoided. Try to combine trips.
The vehicle uses more fuel in winter than in summer, even when other con-
ditions are the same.
“Warming” the engine is not only forbidden in some countries, but in prac-
tice it is technically superfluous as it is a waste of fuel.
Adjusting type pressures.
Having the correct pressure in your tyres helps to reduce rolling resistance
and, as a result reduces fuel consumption. Increasing the tyre pressure
slightly (+ 0.2 bar / + 3 psi / + 200 kPa) can help to save fuel.
When you buy new tyres, make sure they are optimised for minimum rolling
resistance.
Use low friction engine oil
The use of low viscosity totally synthetic oils, known as low friction engine
oil, help to reduce fuel consumption. Low friction engine oils reduce the re-
sistance caused by friction in the engine, they flow around the engine more
quickly and efficiently, particularly in cold starts. The effect is particularly
noticeable in vehicles frequently used for short journeys.
Always check the engine oil level and observe service intervals (engine oil
change intervals).
When purchasing engine oil, always observe legal requirements and ensure
that the oil is approved by SEAT.
Avoid carrying unnecessary loads
The lighter the vehicle, the more economical and ecological the driving
style. For example, an additional weight of 100 kg will increase fuel con-
sumption up to 0.3 ltr/100 km.
Remove any unnecessary objects or loads from the vehicle. Remove optional equipment and unnecessary accessories
The more aerodynamic the vehicle, the lower the fuel consumption. Option-
al equipment and accessories (such as roof racks or bike carriers) reduce
the aerodynamic benefits of the vehicle.
Therefore, we recommend you remove all optional and unnecessary equip-
ment and racks, especially if you intend to drive at high speeds.

WARNING (Continued)
– If you are using a metal fuel canister, the nozzle must always touch
the canister while it is being filled to avoid static electricity.
– Follow the legal requirements for the use, storage and transport of
spare fuel canisters.
– Insure that the fuel container complies with manufacturing stand-
ards, for example, ANSI or ASTM F852-86.
CAUTION
● Always remove any fuel spilled anywhere on the vehicle to avoid dam-
age to the wheel housing, the tyre and vehicle paintwork.
● Refuelling a petrol engine with diesel can cause serious engine and fuel
system damage; the resulting malfunctions are not covered by the SEAT
warranty. If you refuel with the wrong type of fuel, never start the engine.
This applies to even the smallest amount of the wrong fuel. You should ob-
tain professional assistance. With the engine running, the composition of
the wrong fuel could significantly damage the fuel system and the engine
itself.
For the sake of the environment
Fuels can contaminate the environment. Collect any spilt service fluids and
allow a professional to dispose of them. Control lamps and fuel gauge

Several warning and control lamps light up for a few seconds when the igni-
tion is switched on while a test of the function is being carried out. They will
switch off after a few seconds.
In natural gas engines
The warning lamp  lights up when both fuel types (petrol and natural gas)
have reached reserve level.
The warning lamp  lights up when the vehicle is running in natural gas op-
erating mode. The warning lamp 
switches off when the natural gas is exhausted. The
engine changes to operate with petrol.
Problem: If the vehicle is left parked for a long time immediately after refuel-
ling, the gas level indicator does 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 techni-
cal reasons after a cooling phase immediately after refuelling.
WARNING
Driving with insufficient fuel reserve could result in the vehicle breaking
down in traffic and a serious accident.
● If the fuel level is too low then the fuel supply to the engine can be-
come irregular especially on slopes.
● If the engine “is choked” or stalls due to lack of or irregularity of the
fuel supply, the power steering as well as all of the driver assistance sys-
tems including braking assistance will stop working.
● Always refuel when there is only one quarter of the fuel tank left to
avoid running out of fuel.
CAUTION
● Always pay attention to any lit lamps and to the corresponding descrip-
tions and instructions to avoid damage to the vehicle.
● Never run the fuel tank completely dry. An irregular fuel supply may lead
to ignition faults and unburnt fuel could enter the exhaust system. This
could damage the catalytic converter.

Types of fuel
The type of fuel to use when refilling will depend on the vehicle's engine.
You will find a factory-fitted sticker containing information on the type of
fuel for your vehicle on the inside of the fuel tank flap.
SEAT recommends the use of sulphur-free or low sulphur fuel to reduce con-
sumption and prevent engine damage.

Petrol types
Vehicles with petrol engines must refuel using unleaded petrol according to
European norm EN 228 ⇒ 
.
Petrol types are categorised according to their octane number (e.g. 91, 95,
98 or 99 RON (RON = “Research Octane Number”). You may use petrol with
a high octane number than the one recommended for your engine. Howev-
er, this has no advantage in terms of fuel consumption and engine power.
SEAT recommends refuelling with a low sulphur content or sulphur-free fuel
to reduce fuel consumption for petrol engines.
Petrol additives
The quality of the fuel influences running behaviour, performance and serv-
ice life of the engine. Therefore, it is recommended to refuel with good qual-
ity petrol containing the corresponding petrol additives. These additives will
help to prevent corrosion, keep the fuel system clean and prevent deposits
from building up in the engine.
If good quality petrol with additives are not available or engine problems
arise, the necessary additives must be added when refuelling ⇒ 
.
Vehicle diagramPrior to a journey...While drivingCare, cleaning and mainte-
nanceIf and whenTechnical Data

178At the filling station
Not all petrol additives have been shown to be effective. The use of unsuita-
ble petrol additives could seriously damage the engine and the catalytic
converter. Petrol additives with metal additives must never be used.
Available petrol additives for improvements in Anti-detonation ratings or oc-
tane ratings may contain metal additives ⇒ 
.
SEAT recommends “Genuine SEAT Additives for petrol engines”. These addi-
tives are available from Specialised workshops, who will inform you of their
application.
CAUTION
● Only use fuel with an octane rating that is in line with the norm EN 228,
otherwise significant damage could be caused to the engine and fuel sys-
tem. Furthermore, it could lead to a loss of performance with the conse-
quent engine fault.
● The use of unsuitable petrol additives could seriously damage the en-
gine and the catalytic converter.
● If, in exceptional circumstances, petrol with a lower octane rating to that
recommended is used, only use moderate engine speeds and a light throt-
tle. Avoid using full throttle and overloading the engine. Otherwise engine
damage may occur. Fill up with fuel of a suitable octane rating as soon as
possible.
● Do not refuel if the filler indicates that the fuel contains metal. LRP (lead
replacement petrol) fuels also contain high concentrations of metal addi-
tives. This could damage the engine!
● Just filling one full tank of leaded fuel or with other metal additives
would seriously impair the efficiency of the catalytic converter and could
damage it. 
Natural gas
Natural gas, in addition to others, can be in 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 when using one type of gas only.
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.
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.
● Immediately extinguish cigarettes.
● 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!
● You should obtain professional assistance. Have the fault repaired. 
