2015 Seat Leon 5D start stop button

Operation
If the selector lever is placed in position R
durin g the s
t
opping phase, the engine will
start up again.
Change from position D to P to prevent the
engine from accidentally starting when
changing and passing by position R. Note
● You c an c

ontrol whether the engine should
switch off or not by reducing or increasing the
brake force applied. While the vehicle re-
mains stopped, the engine will not stop if the
brake pedal is slightly pressed, in traffic jams
with frequent stopping and starting for exam-
ple. As soon as strong pressure is applied to
the brake pedal, the engine will stop.
● In vehicles with manual gearbox, during
the stop
ping phases the brake pedal must re-
main depressed to prevent the vehicle from
moving.
● If the engine “stalls” in vehicles with man-
ual g
earbox, it can be directly started up
again by immediately pressing the clutch
pedal. General notes

Function and operation Fig. 212
On the instrument panel display:
tir edne
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
b
utt
on  on the multi function steering
wheel

Conditions of operation
Driving behaviour is only calculated on
speeds above about 65 km/h (40 mph) up to
around 200 km/h (125 mph).
Switching on and off
Tiredness detection can be activated or deac-
tivated in the Easy Connect system with 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.
Parking aid
General
information Various systems are available to help you
when p
ark
in

g or manoeuvring in tight
spaces, depending on the equipment fitted
on your vehicle.
The rear parking aid is an audible assistant
that warns about obstacles located behind
the vehicle ›››
page 213.
During parking, Parking System Plus assists
the driver by visually and audibly warning
them about obstacles detected in front and
behind the vehicle ›››

CAUTION
● If an y
fuel is spilt onto the vehicle, it
should be removed immediately. It could oth-
erwise damage the paintwork.
● Never run the tank completely dry. An irreg-
ular f
uel supply could cause misfiring. As a
result, unburnt fuel could enter the exhaust
system and damage the catalytic converter.
● When filling the fuel tank after having run it
compl
etely dry on a vehicle with a diesel en-
gine, the ignition must be switched on for at
least 30 seconds before starting the engine.
When you then start the engine it may take
longer than normal (up to one minute) to
start firing. This is because air needs to be
bled from the fuel system while starting. For the sake of the environment
Do not overfill the fuel tank, it may cause the
fuel t

o overflow if it becomes warm. Note
Diesel vehicles are fitted with a protective de-
vic e th

at prevents the insertion of the wrong
fuel hose 1)
. It is only possible to refuel with
Diesel nozzles.
● If the pump nozzle is worn, damaged, or if
it is
very small, it is possible that it will not
be able to open the protective device. Before
trying to insert the pump nozzle by turning it, try a different pump or request specialist
help.
●
If

you fill the tank from a reserve fuel canis-
ter, the pr
otective device will not open. One
way to resolve this is to pour the fuel in very
slowly. Refuelling with natural gas

The vehicle is not prepared for refuelling with
liquefied natural gas (LNG) ››› . Before refu-elling with natural gas, make sure you add
the ap

ate type of fuel ››› page 243.
Opening the fuel tank cap
The natural gas filler mouth is behind the fuel
tank cap, next to the petrol filler mouth.
● Unlock the vehicle with the key or with the
central
locking button  situated on the driv-
er door ››

● Press on the rear area of the flap and open
it.
Ref

uelling
Special feature: if the ambient temperature is
very high, the natural gas pump protection
against overheating disconnects this auto-
matically.
● Remove the plug from the gas filler mouth
›››
Fig. 233 1 .
● Connect the pump filling nozzle to the gas
fi l
l

er mouth.
● The fuel tank will be full when the p
ump
compressor automatically cuts the supply.
● If you wish to finish refuelling in advance,
pres
s the button on the pump to stop the
flow. 1)
