Driving
Exhaust gas filtration system Catalytic converter
Applies to vehicles with petrol engine:
the
vehicle must only be used with unleaded pet-
rol, otherwise the catalytic converter will be
irreparably damaged.
Never drive until the tank is empty; an irregu-
lar supply of fuel can cause faulty combus-
tion. In these cases, unburned fuel reaches
the exhaust system, which can overheat and
damage the catalytic converter.
Diesel particulate filter
Applies to vehicles with diesel engine: the
diesel engine particulate filter eliminates
most of the soot from the exhaust gas sys-
tem. Under normal driving conditions, the fil-
ter cleans itself. The diesel particulate filter is
cleaned automatically without need for indi-
cation by the warning lamp . This may be
noticed because the engine idle speed in-
creases and an odour may be detected.
If automatic filter purification cannot be car-
ried out (because only short trips are taken,
for example), soot will accumulate on the fil-
ter and the Diesel particulate filter warning
lamp will  switch on.
Facilitate the automatic filter cleaning proc-
ess by driving in the following manner: drive
for approximately 15 minutes at a minimum
speed of 60 km/h in 4th or 5th gear (auto- matic gearbox: gear S). Maintain the engine
speed at approximately 2,000 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
specialised 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 fil-
ter), do not park the vehicle where the ex-
haust can come into contact with flammable
materials under the car (e.g. on grass or at
the forest edge). Fire hazard!
● Do not apply wax underneath the vehicle
around the area of the exhaust system: Fire
hazard! Driving through flooded roads
To prevent damage to the vehicle when driv-
ing through water, for example, along a floo-
ded road, please observe the following:
● The water should never come above the
lower edge of the bodywork.
● Drive at pedestrian speed. WARNING
After driving through water, mud, sludge,
etc., the braking effect can be delayed slight-
ly due to moisture build-up on the discs and
brake pads. Applying the brakes carefully
several times will remove the moisture and
restore the full braking effect. CAUTION
● Driving through flooded areas may severely
damage vehicle components such as the en-
gine, transmission, running gear or electrical
system.
● Whenever driving through water, the Start-
Stop system* must be switched off
››› page 148. Note
● Check the depth of the water before enter-
ing the flooded zone.
● Do not stop in the water, drive in reverse, or
stop the engine in any situation.
● Note that vehicles travelling in the opposite
direction may splash water that could exceed
the maximum permitted water height for your
vehicle.
● Avoid driving through salt water (corro-
sion). 141Technical specifications

The essentials

Advice
SEAT recommends “genuine Volkswagen
Group Fuel Additives for petrol engines”.
These additives can be bought at SEAT deal-
ers, 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
met a
l 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 may 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 tank flap.
We recommend the use of
diesel fuel which
c omp

lies 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). Water in the fuel filter
1)
If your vehicle has a diesel engine and is
equipped with a
fuel filter with a water sepa-
rator, the instrument panel may display the
following warning:  Water in the fuel filter.
If thi

s is the case, take the vehicle to a speci-
alised workshop so that they can drain the
fuel filter. CAUTION
● The vehicle 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
performance problems. Natural gas
Natural gas
Natural gas can be compressed or in liquid
form, addition to others.
