2016 Seat Leon 5D fuel consumption

Driving
the Start-Stop system it is worth switching off
the en gine, f
or e
xample, 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 already
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 dur-
ing this initial warm-up phase. It is therefore
best to drive off immediately after starting
the engine. 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 re-
turn to a normal level.
Check tyre pressure
Always make sure the tyres are inflated to the
correct pressures ››› page 272 to save fuel. If
the pressure is below half bar, fuel consump-
tion may increase by 5%. Due to the greater
rolling resistance, under-inflation also increa-
ses tyre wear and impairs handling.
Do not use winter tyres all year round as they
increase fuel consumption by up to 10%.
Avoid carrying unnecessary loads
Given that every kilo of extra weight will in-
crease the fuel consumption, it is advisable
to always check the luggage compartment to
make sure that no unnecessary loads are be-
ing transported.
Since the luggage rack increases the aerody-
namic drag of the vehicle, you should remove
it when not needed. At speeds of 100-120
km/h (62-75 mph), this will save 12% of fuel.
Save electrical energy
The engine drives the alternator, thereby gen-
erating electricity. This implies that any in-
crease in power consumption also increases
fuel consumption! For this reason, switch off any unneeded electrical devices. Devices that
use a lot of
electricity includes the blower at
a high setting, the rear window heating or
the seat heating*.

SEAT Drive Profile enables the driver to
choose between four profiles or modes, Nor-
mal , Sport , Eco and Individual , that
modify the behaviour of various vehicle func-
tions, providing different driving experiences.
In the FR and X-PERIENCE models equipped
with dynamic chassis control, the Comfort
profile is also available.
In the Leon Cupra model the four profiles are Comfort , Sport, Cupra and Individual .
The Individual profile can be configured
according to personal preferences. The other
profiles are fixed. 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 en-
gine responds more spontaneously or more
in harmony with the movements of the accel-
erator. Additionally, when Eco mode is selec-
ted, the Start-stop function is automatically
activated.
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, Eco1)

Advice
In these situations you will be aware that the
po w
er m
anagement system is intervening to
control the distribution of electrical power.
When the vehicle is parked for long periods
If you do not drive your vehicle for a period of
several days or weeks, the power manage-
ment will gradually shut off the electrical de-
vices one by one or reduce the amount of cur-
rent they are using. This limits the amount of
power consumed and helps to ensure relia-
ble starting even after a long period. Some
convenience functions, such as remote vehi-
cle opening, may not be available under cer-
tain circumstances. These functions will be
restored when you switch on the ignition and
start the engine.
With the engine switched off
For example, if you listen to the sound sys-
tem with the engine switched off the battery
will run down.
If the energy consumption means there is a
risk that the engine will not start, a text will
appear in vehicles with a driver information
system*.
This driver indicator tells you that you must
start the engine so that the battery can re-
charge. When the engine is running
Although the altern
ator generates electrical
power, the battery can still become dis-
charged while the vehicle is being driven.
This can occur when a lot of power is being
consumed but only a small amount supplied,
especially if the battery is not fully charged
initially.
To restore the necessary energy balance, the
system will then temporarily shut off the elec-
trical devices that are using a lot of power, or
reduce the current they are consuming. Heat-
ing systems in particular use a large amount
of electrical power. If you notice, for instance,
that the seat heating* or the rear window
heater is not working, they may have been
temporarily switched off or regulated to a
lower heat output. These systems will be
available again as soon as sufficient electri-
cal power is available.
You may also notice that the engine runs at a
slightly faster idling speed when necessary.
This is quite normal, and no cause for con-
cern. The increased idling speed allows the
alternator to meet the greater power require-
ment and charge the battery at the same
time. Checking and refilling levels

fuel tank is “full”. Do not try to put in more
fuel after the nozzle cuts out, as this will fill

Advice
is equipped with a particulate filter, the sul-
phur c ont
ent
of the fuel must be below 50
parts per million.
Winter-grade diesel
Summer fuel becomes thicker in winter and it
is more difficult to start the engine. For this
reason, petrol stations in some countries al-
so offer winter diesel with improved fluidity
when cold (winter-grade diesel).
Water in the fuel filter 1)
If your vehicle has a diesel engine and is
equipped with a fuel filter with a water sepa-
rator, the instrument panel may display the
following warning:  Water in the
fuel filter. If this is the case, take the
vehicle to a specialised workshop so that
they can drain the fuel filter. CAUTION
● The v ehic

le is not designed for the use of
FAME fuel (biodiesel). The fuel system would
be damaged if you used biodiesel.
● Do not mix fuel additives, the so-called
“thinners”, petro
l or similar additives with
diesel fuel.
● If poor-quality diesel fuel is used, it may be
neces
sary to drain the fuel filter more fre-
quently than is specified in the Maintenance Programme. We recommend having this done
by
a s

pecialised workshop. If water is allowed
to collect in the filter, this can cause engine
performance problems. Natural gas


table on page 2
Natural gas
Natural gas can be compressed or in liquid
form, addition to others.
Liquefied natural gas (LNG) is the result of
heavy cooling of natural gas. Therefore its
volume is considerably reduced compared
with compressed natural gas (CNG). In vehi-
cles with a natural gas engine, liquefied nat-
ural gas cannot be directly refilled, as the gas
would expand excessively in the vehicle gas
tank.
Therefore, vehicles with a natural gas engine
must only be refuelled using compressed
natural gas ››› .
Nat ur
a

l gas quality and consumption
Natural gas is divided into the groups H and
L depending on its quality. Gas type H has a superior heating power and
inferior nitrog

en and carbon dioxide content
than type L. The higher the heating power of
the natural gas, the lower the consumption
will be.
However, the heating power and the propor-
tion of nitrogen and carbon dioxide can fluc-
tuate within the quality groups. Therefore, ve-
hicle consumption can also vary when using
a single type of gas only.
The engine management automatically
adapts to the natural gas used according to
its quality. Therefore, different quality gases
can be mixed in the tank, without the need
for comprehensive draining before applying a
different quality gas.
Updated information relating to natural gas
quality is displayed on the instrument panel
›››  page 30.
Natural gas and safety
If you can smell gas or suspect that there is a
leak ››› :
● Stop the vehicle immediately.
● Switch the ignition off.
● Open the doors to appropriately ventilate
the v
ehic

le.
● Extinguish cigarettes immediately. 1)

Advice
Tyre useful life Fig. 243
Location of the tyre pressure sticker. Correct inflation pressures and sensible driv-
in
g h
ab
its will increase the useful life of your
tyres.
– Check tyre pressure at least once a month,
and also prior to an

y long trip.
– The tyre pressure should only be checked
when the tyre

s are cold. Do not reduce the
pressure of warm tyres.
– Adjust tyre pressure to the load being car-
ried by the

vehicle. –
In vehic
les with a tyre pressure indicator,
save the modified pressure of tyres
››› page 275.
– Avoid fast cornering and hard acceleration.
– Inspect the tyres for irregular wear from
time to time.
The usef

ul life of your tyres depends on the
following factors:
Tyre pressure
Tyre pressure values are indicated on the
sticker on the inside of the fuel tank flap
››› Fig. 243.
Insufficient or excessive pressure greatly re-
duces the useful life of the tyres and adverse-
ly affects vehicle performance and ride. Cor-
rect inflation pressures are very important,
especially at high speeds.
Depending on the vehicle, tyre pressure can
be adjusted to medium load to improve driv-
ing comfort (tyre pressure ). When driving
with comfort tyre pressure fuel consumption
may increase slightly.
The tyre pressure must be adjusted according
to the load the vehicle is carrying. If the vehi-
cle is going to carry the maximum load, the
tyre pressure should be increased to maxi-
mum value indicated on the sticker on the in-
side of the fuel tank flap. Do not forget the spare wheel when checking
the tyre 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 Offi-
cial Service.

Using winter tyres with V-rating
Please note that the generally applicable
240 km/h (150 mph) speed rating for winter
tyres with the letter V is subject to technical
restrictions; the maximum permissible
speed for your vehicle may be significantly
lower. The maximum speed limit for these
tyres depends 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 for
the wint er ty

res fitted on your car can cause
tyre failure, resulting in a loss of control of
the vehicle – risk of accident. For the sake of the environment
Summer tyres should be fitted again as soon
as po

ssible after the winter period; they give
better handling on roads which are free of
snow and ice. Summer tyres perform with
less rolling noise, tyre wear and – most im-
portant – reduce fuel consumption. 280
