The vehicle uses more fuel in winter than in
summer, even when other conditions are the
same.
"Warming" the engine is not only forbidden
in some countries, but in practice it is techni-
cally 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, 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.
Driving
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
unnecessary 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
consumption (examples):
Fault in engine management.
Driving on hills.
WARNING
Always adapt your speed and the distance to
the vehicles ahead in line with visibility,
weather conditions, the condition of the road
and the traffic situation.

system
Introduction
WARNING
The components of the exhaust system reach
very high temperatures. This could cause a
fire.
Always park your vehicle so that no part of
the exhaust system can come in contact with
flammable materials (such as dried grass).
Never apply additional underseal or anti-
corrosion coatings to the exhaust pipes, cata-
lytic converter or the heat shields on the ex-
haust system.
