In the windscreen: field of vision of
the Lane As s
i

st system camera. Using the camera located in the windscreen,
the Lane As
s
i

st system detects the possible
lines dividing the lanes. When the vehicle in-
voluntarily approaches a dividing line it has
detected, the system notifies the driver with
a corrective steering movement . This move-
ment can be over-regulated at any time.
No warning is produced with the turn signals
activated, given that the Lane Assist system
understands that a lane change is required.
Steering wheel vibration
The following situations can cause vibration
in the steering wheel and require the driver
to take active control of driving:

Driver assistance systems
In the FR and X-PERIENCE models equipped
w ith dy
n
amic chassis control and Navi Sys-
tem Plus, 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-
hic
l
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 r

educed.
In manual gearbox vehicles, Eco1)
mode cau-
ses the gear change recommendation indica-
tions that appear on the instrument panel to
vary, facilitating more efficient driving.
Dynamic chassis control (DCC)

››› table on page 2
DCC continuously adapts the shock absorb-
ers to the condition of the road and current
driving conditions, according to the pre-set
programme.
In the event of a fault in the DCC, the follow-
ing message is displayed on the instrument
screen Fault: damping setting .
Address
Power steering becomes more robust in
Sport mode to enable a sportier driving
style. In the Leon Cupra the power steering
becomes more robust in Cupra mode.
Air conditioning
In vehicles with Climatronic, this can operate
in eco 1)
mode, especially restricting fuel con-
sumption. Ambient lighting
The ambient lightin
g guides located in the in-
terior front door panels of the Leon FR and
the Leon Cupra change colour from white to
red depending on the driving mode selected.
Adaptive Cruise Control (ACC) 2)
According to the active driving profile, the ac-
celeration gradient of the adaptive cruise
control varies.
Electronic self-locking differential 2)
The self-locking differential adapts its behav-
iour depending on the driving profile chosen.
Normal mode or Cupra mode can be selected
to prioritise improved traction in sport driv-
ing. 1)

ormation on speed limits or if
overtaking is prohibited at that moment.
The traffic signs and additional information
detected by the system are represented on
the instrument panel display and in the visu-
al presentation of the Infotainment system
(representation of the navigation system
map).
Countries in which it works
When this instruction manual went to print,
the traffic sign detection system was operat-
ing in the following countries:
Andorra, Austria, Belgium, Bulgaria, Croatia,
Czech Republic, Denmark, Finland, France,
Germany, Greece, Hungary, Ireland, Italy, Lux-
embourg, the Netherlands, Norway, Poland,
Portugal, Romania, San Marino, Slovakia,
Slovenia, Spain, Sweden, Switzerland, the
United Kingdom and the Vatican City. WARNING
The technology in the traffic sign detection
sys t

em cannot change the limits imposed by
the laws of physics and only works within the
system's limits. Do not let the extra conven-
ience afforded by the traffic sign detection system tempt you into taking any risks when
drivin
g.

The system is not a replacement for
driver awareness.
● Adapt your speed and driving style to suit
vis
ibility, weather, road and traffic condi-
tions.
● Poor visibility, darkness, snow, rain and fog
may
lead to the system failing to display traf-
fic signs or not displaying them correctly.
● If the camera's field of vision is dirty, cov-
ered or dam
aged, system operation may be
impaired. WARNING
The driving recommendations and traffic indi-
cation s

shown on the traffic sign detection
system may differ from the actual current
traffic situation.
● The system may not detect or correctly
show al
l the traffic signs.
● Traffic signs and traffic regulations have
priority ov
er the recommendations and dis-
plays provided by the system. Note
In order not to compromise the system's op-
eration, p l

ease take the following points into
account:
● Regularly clean the area of vision of the
camera and k
eep it in a clean state, without
snow or ice. ●
Do not c o

ver the field of vision of the cam-
era.
● Check that the windscreen is not damaged
in the area of
the camera's field of vision. Note
● The u se of out

dated maps on the naviga-
tion system may cause the system to show
traffic signs incorrectly.
● In the route points mode of the navigation
syst
em, the traffic sign detection system is
only partly available. 208

table on page 2
The Tiredness detection informs the driver
when their driving behaviour shows signs of
fatigue. WARNING
Do not let the comfort afforded by the Tired-
nes s

detection system tempt you into taking
any risks when driving. Take regular breaks,
sufficient in length when making long jour-
neys.
● The driver always assumes the responsibil-
ity of driv
ing to their full capacity. ●
Never driv e if

you are tired.
● The system does not detect the tiredness of
the driver in al
l circumstances. Consult the in-
formation in the section ››› page 211, System
limitations.
● In some situations, the system may incor-
rectly int
erpret an intended driving manoeu-
vre as driver tiredness.
● No warning is given in the event of the ef-
fect c
alled microsleep!
● Please observe the indications on the in-
strument p
anel and act as is necessary. Note
● Tiredne s

s detection has been developed for
driving on motorways and well paved roads
only.
● If there is a fault in the system, have it
check
ed by a specialised workshop.210

s
s detection symbol. Tiredness detection determines the driving
beh
av
iour of

the driver when starting a jour-
ney, making a calculation of tiredness. This is
constantly compared with the current driving
behaviour. If the system detects that the driv-
er is tired, an audible warning is given with a
sound and an optic warning is shown with a
symbol and complementary message on the
instrument panel display ››› Fig. 212. The
message on the instrument panel display is
shown for approximately 5 seconds, and de-
pending on the case, is repeated. The system
stores the last message displayed.
The message on the instrument panel display
can be switched off by pressing the button on the windscreen wiper lever or the

System limitations
The Tiredness detection has certain limita-
tions inherent to the system. The following
conditions can limit the Tiredness detection
or prevent it from functioning. ● At speeds below 65 km/h (40 mph)
● At speeds above 200 km/h (125 mph)
● When cornering
● On roads in poor condition
● In unfavourable weather conditions
● When a sporty driving style is employed
● In the event of a serious distraction to the
driver Tir
edne
ss detection will be restored when the
vehicl
e is stopped for more than 15 minutes,
when the ignition is switched off or when the
driver has unbuckled their seat belt and
opened the door.
In the event of slow driving during a long pe-
riod of time (below 65 km/h (40 mph) the
system automatically re-establishes the tired-
ness calculation. When driving at a faster
speed the driving behaviour will be recalcula-
ted.

● Never refuel with fuels containing a large
proportion of
ethanol (for example, E50, E85).
This could damage the fuel system.
● Just filling one full tank of leaded fuel or

● In those countries where unleaded petrol is
not avai
lable, you may refuel with a fuel with
a low lead content. Diesel fuel
Please note the information on the inside of
the f
uel
t

ank flap.
We recommend the use of diesel fuel which
complies to European standard EN 590. If
diesel fuel which meets European standard
EN 590 is not available, the Cetane number
(CZ) must, at minimum, be 51. If the engine
is equipped with a particulate filter, the sul- phur content 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 1)

to c
o

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 nitrogen and carbon dioxide content
than type L. The higher the heating power of the natural gas, the lower the consumption
wil

l 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 31.
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.
● Move away from the vehicle or switch off
obj
ects that may cause sparks or a fire.
● If you continue to smell gas, do not contin-
ue drivin g! ●
Seek s pec

ialist assistance. Have the fault
repaired. WARNING
Failure to act when you can smell gas in the
vehic l

e or when refuelling can cause serious
injuries.
● Carry out the necessary operations.
● Leave the danger zone.
● If necessary, warn the emergency services. WARNING
The vehicle is not prepared to use liquefied
nat ur

al gas (LNG) and this fuel must not be
added under any circumstances. Liquefied
natural gas can cause the natural gas tank to
explode, resulting in serious injury. Note
Have the natural gas system checked regular-
ly b y

a specialised workshop, according to
the Maintenance Programme. 245
