2013 Seat Leon 5D fuel filter

Driving and the environment
Never drive until the tank is empty; an irregular supply of fuel can cause
faulty combustion. In these cases, unburned fuel reaches the exhaust sys-
tem, which can overheat and damage the catalytic converter.
Diesel particulate filter
Applies to vehicles with diesel engine: The diesel particulate filter can filter
out almost all soot particles contained in the exhaust gas. In normal driving
conditions the filter is self-cleaning. The Diesel particulate filter is cleaned
automatically without need for indication by the warning lamp . This may
be noticed because the engine idle speed increases and an odour may be
detected.
If automatic filter purification cannot be carried out (because only short
trips are taken, for example), soot will accumulate on the filter and the Die-
sel particulate filter warning lamp will  switch on.
Facilitate the automatic filter cleaning process by driving in the following
manner: Drive for approximately 15 minutes at a minimum speed of 60 km/
h (40 mph) in 4th or 5th gear (automatic gearbox: gear S). Maintain the en-
gine speed at approx. 2000 rpm. The rise in temperature causes the soot on
the filter to burn. On completion of the cleaning the warning lamp will
switch off. If the warning lamp does not switch off, go immediately to a spe-
cialised workshop to rectify the problem.
WARNING
● Because of the high temperatures which can occur in the exhaust gas
control system (catalytic converter or diesel particulate filter), do not
park the vehicle where the exhaust can come into contact with flamma-
ble materials under the car (e.g. on grass or at the forest edge). Fire haz-
ard!
● Do not apply wax underneath the vehicle around the area of the ex-
haust system: Fire hazard!
 Economic and ecological driving
Fuel consumption, environmental pollution and wear to the engine, brakes
and tyres depends largely on driving style. Fuel consumption can be re-
duced by 10-15% with an economical driving style and proper anticipation
of traffic conditions. The following section gives you some tips on lessening
the impact on the environment and reducing your operating costs at the
same time.
Foresight when driving
Acceleration causes the vehicle to consume more fuel. If you think ahead
when driving, you will need to brake less and thus accelerate less. Wherever
possible, let the car roll slowly to a stop, with a
gear engaged (for instance
when you can see that the next traffic lights are red). This takes advantage
of the engine braking effect, reducing wear on the brakes and tyres. Emis-
sions and fuel consumption will drop to zero due to the overrun fuel cut-off.
Changing gear to save energy
An effective way of saving is to change in advance to a higher gear. Running
the engine at high rpm in the lower gears uses an unnecessary amount of
fuel.
Manual gearbox : shift up from first to second gear as soon as possible. In
any case, we recommend that you change to a higher gear upon reaching
2000 rpm or so. Choosing the right gear enables fuel savings. Select the
highest possible gear appropriate for the driving situation (the engine
should continue functioning with cyclical regularity).
Automatic gearbox : accelerate gradually and without reaching the “kick-
down” position.
Avoid driving at high speed
Avoid travelling at top speed, whenever possible. Fuel consumption, emis-
sion of harmful gases and noise pollution multiply disproportionately as
speed is increased. Driving at moderate speeds will help to save fuel. 

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. 
