Start and driving
temperature for the vehicle is not too different
t
o the outside t
emper
ature. It is a good idea
to air the vehicle before starting your journey
and to drive a short distance with the win-
dows open. Then you can close the windows
and switch on the air conditioning. Keep win-
dows closed when travelling at high speeds.
Driving with the windows open increases fuel
consumption.
●
Switch off the seat heating when the seats
have warmed up.
●
Switch off the heated rear window when it
is not moist or covered in ice.
Avoid short journeys
Fuel consumption is much higher when the
engine is cold, immediately after it has been
started. It takes a few kilometres of driving for
the engine to warm up and to normalise con-
sumption.
The engine and catalytic converter need to
reach their proper working temperature in
order to minimise fuel consumption and emis-
sions. The ambient temperature has a deci-
sive influence.
Fig. 165 shows the difference in consumption
for the same journey at +20°C (+68°F) and at
-10°C (+14°F).
Therefore, unnecessary short journeys should
be avoided. Try to combine trips.
The vehicle uses more fuel in winter than in
summer, even when other conditions are the
same.
The engine takes a long time to warm up
when it is idling. In addition, mechanical wear
and pollutant emissions are also especially
high during this initial warm-up phase. It is
therefore best to drive off immediately after
starting the engine. Doing this avoids running
the engine at a high speed.
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, helps to re-
duce fuel consumption. These oils reduce the
resistance 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 ob-
serve service intervals (engine oil change in-
tervals).
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 consumption up to 0.3 l/100 km.
Remove any unnecessary objects or loads
from the vehicle.
Remove optional equipment and unneces-
sary accessories
The more aerodynamic the vehicle, the lower
the fuel consumption. Optional equipment
and accessories (such as roof racks or bike
carriers) reduce the aerodynamic benefits of
the vehicle.
Therefore, we recommend you remove all op-
tional and unnecessary equipment and
racks, especially if you intend to drive at high
speeds.
Other factors which increase fuel con-
sumption (examples):
●
Fault in engine management.
●
Driving on hills.
