Advice
CAUTION
●
Do not ref
uel 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 example, E50, E85).
This could damage the fuel system.
●
Just filling one full tank of leaded fuel or
fuel containing other metal additives would
seriously impair the efficiency of the catalytic
converter.
●
Only use fuel additives that have been ap-
proved by SEAT. Octane boosting 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 ma
y use petrol with a high octane num-
ber than the one recommended for your en-
gine.
●
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 t
ank 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 available, the Cetane number
(CZ) must, at minimum, be 51. If the engine
is equipped with a particulate filter, the sul-
phur 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 al-
so offer winter diesel with improved fluidity
when cold (winter-grade diesel).
CAUTION
●
The vehic
le is not designed for the use of
FAME fuel (biodiesel). The fuel system would
be damaged if you used biodiesel.
●
Do not mix fuel additives, the so-called
“thinners”, petrol or similar additives with
diesel fuel.
●
If poor-quality diesel fuel is used, it may be
necessary to drain the fuel filter more fre-
quently than is specified in the Maintenance
Programme. We recommend having this done
by a specialised workshop. If water is allowed
to collect in the filter, this can cause engine
perform
ance problems.
Selective catalytic reduction*
(AdBlue)
Introduction
In vehicles with “Selective Catalytic Reduc-
tion”, a speci
al urea solution (AdBlue) is in-
jected into the exhaust gas system in front of
the catalytic converter to reduce nitrogen ox-
ide emissions.
The consumption of AdBlue depends on indi-
vidual driving style, the temperature at which
the system operates and the outside temper-
ature where the vehicle is driven.
AdBlue is kept in an independent tank in the
vehicle and should be refilled at an official
supplier. The AdBlue tank holds approxi-
mately 17 litres.
The AdBlue fill level must be checked when
the vehicle is being serviced.
WARNING
If the AdBlue fill level is too low, the vehicle
may
not restart after switching the ignition
off. The emergency start or jump start will not
be possible either!
