Fuel consumption in litres per 100 km

, br
ak

e and tyre wear depend largely
on three factors:

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.

Start and driving
For the sake of the environment
Even when the emission control system is
working perf ectly, ther
e may be a smell of
sulphur under certain conditions. This de-
pends on the sulphur content of the fuel
used. Driving tips
Driving abroad In some countries, certain safety regulations
and r
equir
ements ar

e in force relating to ex-
haust gas emissions, which differ from the
technical characteristics of the vehicle. Be-
fore travelling abroad, SEAT recommends
you consult a technical service about the le-
gal requirements and the following points:

are on the pump and the tank lid of your vehi-
cle. The identification serves to prevent con-
fusion when choosing the fuel.
Petrol with ethanol (“E” stands for Etha-
nol). The number indicates the percent-
1 age of ethanol in the petrol. “E5” means,
f
or e
x

ample, an ethanol ratio of 5% max.
Diesel with biodiesel (“B” stands for Bio-
diesel). The number indicates the per-
centage of biodiesel in the diesel. “B7”
means, for example, a proportion of bio-
diesel of max. 7%.
Natural gas: “CNG” means Compressed
Natural Gas.
Type of petrol  Applies to v
ehicl
es: with petrol engine
The correct grade of petrol is listed inside the
fuel tank flap.
The vehicle is equipped with a catalytic con-
verter and must only be run on unleaded
petrol. The petrol must comply with the
standard EN 228 and be sulphur-free. Fuels
with a 10% ethanol ratio can be refuelled
(E10) 2)
. The types of petrol are differentiated
by using the octane numbers (RON) or via
the anti-knock index (AKI).
The following pieces of text show the infor-
mation included in the corresponding stickers
on the tank lid (examples): 2 3 Super unleaded petrol 95 octane petrol or

east
We recommend refuelling with super 95 oc-
tane petrol (91 AKI). If not available: normal 91
octane petrol (87 AKI) (with a slight power
loss).
Super unleaded petrol, 95 octanes at
least
You should use super 95 octane petrol (91
AKI) at least.
If super is not available, if necessary, use nor-
mal 91 octane petrol (87 AKI). In this case only
use moderate engine speeds and a light
throttle. Refuel with super as soon as possi-
ble.
Unleaded super plus 98 octane petrol or
super 95 octane petrol at least
We recommend refuelling with super plus 98
octane petrol (93 AKI). If not available: super
95 octane petrol (91 AKI) (with a slight power
loss).
If super is not available, if necessary, use nor-
mal 91 octane petrol (87 AKI). In this case only
use moderate engine speeds and a light 1)
