2020 Seat Leon fuel cap

Start and driving
Description Depending on the equipment fitted in the ve-
hicl
e
, SEAT Drive Profile can operate on the
following functions:
Engine
Depending on the profile selected, the engine
responds more quickly or smoothly to the ac-
celerator being pressed. When the Eco pro-
file is selected, the Start-stop function is acti-
vated.
In vehicles with automatic transmission, the
gear change timing is changed to put the
changes at higher or lower revolutions. The
Eco profile activates the Inertia function,
thereby reducing consumption. The rest of
the driving profiles will activate the inertia use
function when the selector lever is not in the S
position, depending on how the accelerator
pedal is released ››› page 234
. When the ve-
hicle is turned on again, the function is activa-
ted by default to reduce consumption.
With manual transmission, the Eco profile
changes the gear change recommendations
to facilitate more efficient driving.
Dynamic chassis control (DCC)*
The DCC continuously adapts the damping
of the suspension system to the characteris-
tics of the road surface and the driving situa-
tion (speed, acceleration and steering wheel angle) according to the selected driving pro-
fil
e

. The vehicle's dynamic behaviour is also
adapted to improve grip on curves and turn-
ing capacity. Within the Individual profile you
can also adjust the DCC level in a custom-
ised manner.
In the event of a fault in the DCC, the follow-
ing message is displayed on the instrument
screen Fault: shock absorber regula-
tion
Steering
The power steering varies its driving modes
and adapts to the profile selected, thus offer-
ing the best behaviour for each situation.
Air conditioning
The Climatronic can operate in Eco mode
with particularly limited consumption.
Adaptive Cruise Control (ACC)*
Depending on the driving profile, the perform-
ance of the ACC varies, to allow more sporty
acceleration and braking or a more respect-
ful fuel consumption.
PreCrash system
The PreCrash system adapts according to
the selected configuration. The Sport driving
profile has specific settings to adapt to driv-
ing characteristics ››› page 24
. Setting the driving profile There are several ways to select a driving
pr
ofil

e using the infotainment system:

educed.Economical and environmentally
friendly driving
Fuel consumption, environmental pollution
and w
ear t

o the engine, brakes and tyres all
depend largely on driving style. Consumption
can be reduced between 10-15% with an effi-
cient driving type. The following section gives
you some tips on lessening the impact on the
environment and reducing your operating
costs at the same time.
Active cylinder management (ACT®)*
Depending on vehicle equipment, the active
cylinder management (ACT®) may deacti-
vate some of the engine cylinders if the driv-
ing situation does not require too much pow-
er. The number of active cylinders can be
seen on the instrument panel display.

Foresight when driving
If you think ahead when driving, you will need
to brake less and thus accelerate less. Take
advantage of the inertia of the vehicle when-
ever possible, with a gear engaged. This takes advantage of the engine braking effect,
r
educing w

ear on the brakes and tyres. Emis-
sions and fuel consumption will drop to zero.
Changing gear to save energy
An effective way of saving is to change in ad-
vance to a higher gear.
Manual transmission: shift up from first to
second gear as soon as possible. Choosing
the right gear enables fuel savings. Select the
highest possible gear appropriate for the
driving situation (the engine should continue
functioning with cyclical regularity).
Automatic transmission: accelerate gradu-
ally and without reaching the “kick-down”
position.
Avoid driving at high speed
Avoid travelling at your vehicle’s top speed,
whenever possible. Fuel consumption, emis-
sion of harmful gases and noise pollution
multiply as speed is increased. Driving at
moderate speeds will help to save fuel.
Reduce idling time
In vehicles with the Start-Stop system idling is
automatically reduced. In vehicles without
the Start-Stop system it is worth switching off
the engine, for example, at level crossings
and at traffic lights that remain red for long
periods of time. When an engine has reached
operating temperature, and depending on the cylinder capacity, keeping it switched off
for a minimum of about 5 seconds alr
eady
saves more than the amount of fuel necessa-
ry for restarting.
The engine takes a long time to warm up
when it is idling. Mechanical wear and pollu-
tant emissions are also especially high during
this initial warm-up phase. It is therefore best
to drive off immediately after starting the en-
gine. Avoid running the engine at high speed.
Regular maintenance
Regular servicing helps in saving fuel even
before the engine is started. A well-serviced
engine gives you the benefit of improved fuel
efficiency as well as maximum reliability and
an enhanced resale value. A badly serviced
engine can consume up to 10% more fuel
than necessary.
Avoid short journeys
The engine and catalytic converter need to
reach their optimal operating temperature
in order to minimise fuel consumption and
emissions.
A cold engine consumes a disproportionate
amount of fuel. The engine reaches its work-
ing temperature after about four kilometres
(2.5 miles), when fuel consumption will return
to a normal level. »

The flap that covers the tank cap is unlocked
and locked automatically using the central
locking.

Wheels
design of summer tyres (width, rubber com-
pound, tr ead patt
ern) gives less grip on ice
and snow. This applies particularly to vehicles
equipped with wide section tyres or with
high speed tyres (code letters H, V or Y on
the sidewall).
Only use winter tyres of the correct type ap-
proved for your vehicle. The sizes of these
tyres are specified in the vehicle's documents
(e.g. EC Certificate of Conformity or COC 1)
).
The vehicle documentation varies depending
on the country of residence.
Winter tyres lose a great deal of their proper-
ties when the tread is worn down to a depth
of 4 mm.
The performance of winter tyres is also se-
verely impaired by ageing, even if the tread is
still much deeper than 4 mm.
A code letter indicating the speed limit is
stamped on all winter tyres ››› page 346
.
Vehicles capable of exceeding these speeds
must have an appropriate sticker attached
so that it is visible to the driver. Suitable stick-
ers are available from the SEAT Official Serv-
ice and specialised workshop. Please note
the regulations to this effect in your country.
“All-weather” tyres can also be used instead
of winter tyres. Using winter tyres with V-rating
Please not
e that the generally applicable
240 km/h (149 mph) speed for winter tyres
with the letter V is subject to technical re-
strictions; the maximum permissible speed
for your vehicle may be significantly lower.
The maximum speed limit for these tyres de-
pends directly on the maximum axle weights
for your car and on the listed weight rating of
the tyres being used.
It is best to contact a SEAT Official Service to
check the maximum speed which is permissi-
ble for the V-rated tyres fitted on your car on
the basis of this information. WARNING
Exceeding the maximum speed permitted
f or the wint

er tyres fitted on your car can
cause tyre failure, resulting in a loss of con-
trol of the vehicle – risk of accident. For the sake of the environment
When winter is over, change back to sum-
mer t yr

es at an appropriate moment. In
temperatures above +7°C (+45°F), perform-
ance will be improved if summer tyres are
used. Fuel consumption, wear and noises
while driving will all be reduced. Snow chains
Snow chains must only be fitted t
o the fr
ont
wheels, even on vehicles with four-wheel
drive.
