2018 Seat Leon fuel

Driving
Description Depending on the equipment fitted in the ve-
hicle
, SEAT Driv
e Profile can operate on the
following functions:
Engine
Depending on the profile selected, the engine
responds more spontaneously or more in har-
mony with the movements of the accelerator.
Additionally, when Eco mode is selected, the
Start-stop function is automatically activa-
ted.
In vehicles with automatic transmission, the
gear change points are modified to position
them in lower or higher engine speed ranges.
Additionally, the Eco 1)
mode activates the In-
ertia function, enabling consumption to be
further reduced.
In manual gearbox vehicles, Eco 1)
mode cau-
ses the gear change recommendation indi-
cations that appear on the instrument panel
to vary, facilitating more efficient driving.
Dynamic chassis control (DCC)
DCC continuously adapts the shock absorb-
ers to the condition of the road and current driving conditions, according to the pre-set
progr
amme

.
In the event of a fault in the DCC, the follow-
ing message is displayed on the instrument

tion
Address
Power steering becomes more robust in
Sport mode to enable a sportier driving style.
In the Leon Cupra the power steering be-
comes more robust in Cupra mode.
Air conditioning
In vehicles with Climatronic, this can operate
in eco 1)
mode, especially restricting fuel con-
sumption.
Adaptive Cruise Control (ACC) 2)
The acceleration and braking gradient of the
adaptive cruise control varies according to
the active driving profile

Fuel Identification of the fuel 1)Fig. 306
Identification of fuels according to
Eur opean Union (EU) Dir
ectiv
e 2014/94/Fuels are identified with different symbols.
Depending on the fuel, the diff
er
ent symbol

s
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-
age of ethanol in the petrol. “E5” means,
for example, an ethanol ratio of 5% max.
Diesel with biodiesel (“B” stands for Bio-
diesel). The number indicates the per-
1 2 centage of biodiesel in the diesel. “B7”
means, f
or e
x

ample, a proportion of bio-
diesel of max. 7%.
Natural gas: “CNG” means Compressed
Natural Gas.
Type of petrol  Applies to vehicles: with petrol engine
The corr ect gr

ade 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): 3 Super unleaded petrol 95 octane petrol or
normal 91 oct
ane petr
ol at l

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

Practical tips
Do not forget the spare wheel when checking
the t yr
e pr
essures: Keep this spare wheel in-
flated to the highest pressure required for the
road wheels.
In the case of a minimised temporary spare
wheel (125/70 R16 or 125/70 R18) inflate to a
pressure of 4.2 bar as indicated on the tyre
pressure label on the fuel tank flap.
Driving style
Fast cornering, heavy acceleration and hard
braking (squealing tyres) all increase tyre
wear.
Wheel balance
The wheels on new vehicles are balanced.
However, certain circumstances may lead to
imbalance (run-out), which is detected as vi-
brations in the steering wheel.
Unbalanced wheels should be rebalanced,
as they otherwise cause excessive wear on
steering, suspension and tyres. A wheel must
also be rebalanced when a new tyre is fitted
or if a tyre is repaired.
Incorrect wheel alignment
Incorrect running gear alignment causes ex-
cessive tyre wear, impairing the safety of the
vehicle. If you notice excessive tyre wear, you
should check wheel alignment at a SEAT Of-
ficial Service. WARNING
