2014 Seat Leon 5D steering wheel

Operation
Note
The Official Service or a specialist workshop
can tell you if your vehicle is equipped with
this system. Start-Stop system*
Description and operation The Start-Stop system helps save fuel and re-
duce CO
2 emissions.
In Start-Stop mode, the engine will automati-
cally switch off when the vehicle stops, when
stopping at traffic lights for example. The ig-
nition remains switched on during the stop-
ping phase. The engine automatically
switches back on when required.
As soon as the ignition is switched on, the
Start-Stop function is automatically activa-
ted.
Basic requirements for the Start-Stop mode ● The driver door must be closed.
● The driver must have their seat belt fas-
tened.
● The bonnet must be closed.
● The vehicle must have travelled at more
than 4 km/h (2 mph) since the last stop.
● The vehicle cannot be towing a trailer. WARNING
● Never switch the engine off until the vehi-
cle is stationary. The brake servo and power
steering functions will not be completely cov-
ered under warranty. More force may also be
needed to turn the steering wheel or to brake.
As you cannot steer and brake in the normal
manner, there is a greater risk of accidents
and serious injury.
● Never remove the key from the ignition if
the vehicle is in motion. Otherwise, the steer-
ing could lock making it impossible to steer
the vehicle.
● To avoid injury, make sure that the Start-
Stop system is switched off when working in
the engine compartment ››› page 149. CAUTION
The Start-Stop system must always be
switched off when driving through flooded
areas ››› page 149. Stop/Start the engine
Vehicles with a manual gearbox
– When the vehicle is stopped, put it into
neutral and release the clutch pedal. The
engine will switch off. The warning lamp 
will appear on the instrument panel dis-
play. –
When the clutch pedal is pressed the en-
gine will start up again. The warning lamp
will switch off.
Vehicles with an automatic gearbox
– Use the foot brake to bring the vehicle to a
stop and keep the brake pedal pressed
down with your foot. The engine will switch
off. The warning lamp  will appear in the
di s
play.
– When you take your foot off the brake pedal
the engine will start up again. The warning
lamp will switch off.
Additional information related to the
automatic gearbox
The engine stops when the selector lever is in
the positions P, D, N and S, in addition to
when in manual mode. With the selector lev-
er in position P, the engine will also remain
switched off when you take your foot off the
brake pedal. In order to start the engine up
again the accelerator must be pressed, or an-
other gear engaged or the brake released.
If the selector lever is placed in position R
during the stopping 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.

Driver assistance systems
Note
● You can control 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 stopping phases the brake pedal must re-
main depressed to prevent the vehicle from
moving.
● If the engine “stalls” in vehicles with man-
ual gearbox, it can be directly started up
again by immediately pressing the clutch
pedal. General notes
The system can interrupt the Start-Stop mode
frequently for different reasons.
The engine does not switch off
Before the stopping phase, the system veri-
fies whether certain conditions are met. The
engine
does not
sw
it ch off, in the following
situations for example:
● The engine has not yet reached the mini-
mum required temperature for the Start-Stop
mode. ●
The interior temperature selected for the air
conditioner has not yet been reached.
● The interior temperature is very high/low.
● Defrost function button activated
›››  page 26.
● The park

ing aid* is switched on.
● The battery is very low.
● The steering wheel is overly turned or is be-
ing turned.
● If there is a danger of misting.
● After engaging reverse gear.
● In case of a very steep gradient.
The indication  is shown on the instrument
panel display, and in addition, the driver in-
formation system* shows, .
The engine starts by itself
During a stopping phase the normal Start-
Stop mode can be interrupted in the follow-
ing situations: The engine restarts by itself
without involvement from the driver.
● The interior temperature differs from the
value selected on the air conditioner.
● Defrost function button activated
›››  page 26.
● The brak

e has been pressed several times
consecutively.
● The battery is too low.
● High power consumption. Note
In vehicles with an automatic gearbox, if the
selector lever is placed in position D, N or S
after engaging reverse gear, the vehicle must
be driven at a speed faster than 10 km/h (5
mph) for the system to return to conditions in
which the engine can be stopped. Manually switching on/off the Start-
Stop system

Operation
in braking, such as in work areas or if there
are metal rails.
●
If the operation of the City Emergency brak-
ing function is impaired, for example, by dirt
or because the radar sensor has lost its set-
tings, the system may issue unnecessary
warnings and intervene inopportunely in the
braking.
● During driving, the City Emergency braking
function does not react to people or animals
or vehicles crossing your path or which ap-
proach you head-on in the same lane. Note
● When the City Emergency braking function
causes a braking, the brake pedal is “hard-
er”.
● Automatic interventions on the brakes by
the City Emergency braking function may be
interrupted by pressing the clutch, accelera-
tor or moving the wheel.
● The City Emergency braking function can
brake the vehicle until it stops completely.
However, the brake system does not halt the
vehicle permanently. Use the foot brake!
● If several inopportune intervenes occur,
switch off the Front Assist and with it the City
Emergency braking function. Take it to a spe-
cialised workshop, SEAT recommends visiting
a SEAT dealership.
● If numerous unnecessary interventions oc-
cur, the City Emergency braking function may
switch off automatically. Lane Assist system*
Introduction WARNING
The intelligent technology in the Lane Assist
system cannot change the limits imposed by
the laws of physics and by the very nature of
the system. Careless or uncontrolled use of
the Lane Assist system may cause accidents
and injury. The system is not a replacement
for driver awareness.
● Always adapt your speed and the distance
to the vehicles ahead in line with visibility,
weather conditions, the condition of the road
and the traffic situation.
● Always keep your hands on the steering
wheel so it can be turned at any time.
● The Lane Assist system does not detect all
road markings. The road surfaces, road struc-
tures or objects in poor condition can be in-
correctly detected as road markings under
certain circumstances by the Lane Assist sys-
tem. In such situations, switch the Lane As-
sist system off immediately.
● Please observe the indications on the in-
strument panel and act as is necessary.
● Always pay attention to the vehicle's sur-
roundings.
● When the area of vision of the camera be-
comes dirty, covered or is damaged, the Lane
Assist system function can be affected. CAUTION
In order to avoid influencing the operation of
the system, the following points must be tak-
en into account:
● Regularly clean the area of vision of the
camera and keep it in a clean state, without
snow or ice.
● Do not cover the area of vision of the cam-
era.
● Check that the area of vision of the wind-
screen camera is not damaged. Note
● The Lane Assist system has been exclusive-
ly developed for driving on paved roads only.
● If the Lane Assist system does not work as
described in this chapter, do not use it and
contact a specialised workshop.
● If there is a fault in the system, have it
checked by a specialised workshop. 166

Operation
Operating mode Fig. 164
In the windscreen: field of vision of
the Lane Assist system camera. Using the camera located in the windscreen,
the Lane Assist 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
.
Thi s 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 cause vibration in
the steering wheel and require the driver to
take active control of driving:
● When the limits of the very nature of the
system are reached. ●
When the maximum rotational torque dur-
ing the corrective steering movement is not
enough to keep the vehicle inside the lane.
● When no lane is detected during the correc-
tive steering movement.
Switching the Lane Assist system on or off
Through the Easy Connect system
● Push the Easy Connect button CAR ●
Push the Setup function button
● Press the function button driver assistance to
open the menu.
Alternatively: through the driv
in
g assist but-
ton on the turn signal level*.
The Lane centring guide is activated/deactiva- ted in the Easy Connect system using the CAR button and the button on the
Setup function

Self -de

activation:
the Lane Assist system can
be automatically deactivated if there is a sys-
tem malfunction. The control lamp disap-
pears.
Hands-Off Function
● If the driver does not exert any physical ac-
tion on the steering wheel for approximately
10 to 12 sec. the function deactivates.
● Visual and audible warnings on the instru-
ment panel. ●
The function switches off 2 seconds after
the warning.
The lane assist system is active but it is not
available (the control lamp is lit up yellow)
● When driving at speeds below 65 km/h (38
mph).
● When the Lane Assist system does not de-
tect the dividing lines of the road. For exam-
ple, in the event warnings indicating road
works, and snow, dirt, moisture or reflec-
tions.
● When the radius of a curve is too small.
● When no road markings can be seen.
● When the distance to the next marking to
too great.
● When the system does not detect any clear
and active steering movement during a long
period of time.
● Temporarily, in the event of very dynamic
driving styles.
● If a turn signal is activated.
● With the stability control system (ESC) in
Sport mode or switched off. Note
● Before starting a journey, verify that the
field of vision of the camera is not covered

era clean. 168

Operation
WARNING
Please note that if the road surface is slip-
pery or wet, the kick-down feature could
cause the driving wheels to spin, which could
result in skidding. Tiredness detection (break
recommendation)*
Introduction The Tiredness detection informs the driver
when their driving behaviour shows signs of
fatigue.
WARNING
Do not let the comfort afforded by the Tired-
ness 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 driving to their full capacity.
● Never drive if you are tired.
● The system does not detect the tiredness of
the driver in all circumstances. Consult the in-
formation in the section ››› page 172, System
limitations.
● In some s it
uations, the system may incor-
rectly interpret an intended driving manoeu-
vre as driver tiredness. ●
No warning is given in the event of the ef-
fect called microsleep!
● Please observe the indications on the in-
strument panel and act as is necessary. Note
● Tiredness detection has been developed for
driving on motorways and well paved roads
only.
● If there is a fault in the system, have it
checked by a specialised workshop. Function and operation
Fig. 167
On the instrument panel display:
tiredness detection symbol. Tiredness detection determines the driving
behaviour 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. 167 . The
me s

sage 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
button
 on the multi function steering
wheel ››› page 72 .
The me s

sage can be recalled to the instru-
ment panel display using the multifunction
display ››› page 72.
Condition

s 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

Driver assistance systems
As you approach the obstacle, the time inter-
val between the audible warnings will be re-
duced.
If you maintain separation from the obstacle,
the volume of the warning begins to reduce
after four seconds (does not affect the tone
of the constant warning).
Activating/Deactivating Fig. 169
Centre console: parking aid button. Fig. 170
Miniature indication of automatic ac-
tivation Switching on
– Engage reverse gear or
– Press the switch  in the centre console
››› Fig. 169 . A short confirmation signal will
be he ar
d and the button symbol will light
up yellow.
With certain equipment (Adaptive Cruise Con-
trol - ACC), the system will be activated auto-
matically when the vehicle reverses for a cer-
tain distance (about 10 cm if an obstacle is
detected in the rear area and about 20 cm if
no obstacle is detected in the rear area).
Switching off
– Drive forwards at more than 10 km/h (6
mph), or
– Press the  button, or
– switch the ignition off. Segments of the visual indication
The distance of separation from the obstacle
can be estimated using the segments around
the vehicle.
The graphic display of the segments varies
according to the vehicle's equipment:
The yellow trail indi-
cates the vehicle's expected journey
based on the steering wheel angle. A
white
segment is displayed when the
obstacle is not within the vehicle's tra-
jectory or the direction of travel would
avoid it entering the vehicle's trajectory.
If the obstacle is within the vehicle’s tra-
jectory, a yellow segment is displayed
(at

a distance of more than 30 cm) or a
red
segment (at a distance of less than
30 cm) at the same time as the corre-
sponding audible warning sounds.
The
yellow trail indicates the vehicle's ex-
pected journey based on the steering
wheel angle. A white segment is dis-
pl

ayed when the obstacle is not within
the vehicle's trajectory or the direction
of travel would avoid it entering the ve-
hicle's trajectory. If the obstacle is with-
in the vehicle’s trajectory, a red
segment
is displayed at the same time as the cor-
responding audible warning sounds. »

Advice
The retract function may not operate properly
in very dirty belts. Make sure that the inertia
reel seat belts are completely dry before al-
lowing them to retract. CAUTION
● Do not remove the seat belts from the vehi-
cle to clean them.
● Do not use chemical cleaning agents on the
seat belts, as this can damage the webbing.
Ensure that the seat belts do not come into
contact with corrosive fluids.
● If you find any damage to the belt webbing,
belt fittings, the belt retractor or the buckle,
the belt in question must be replaced by a
specialised workshop. Intelligent technology
Electro-mechanical steering Electro-mechanical power steering assists
the driver when steering.
Electro-mechanical power steering adapts
electronically to the speed of the car, torque
and t
urnin
g angle.
If the power steering should fail at any time
or the engine is switched off (for instance
when being towed), the car can still be
steered. However, more effort than normal
will be required to turn the steering wheel.
Driver warning lamps and messages  (in red) Faulty steering! To park the vehicle
If the warning lamp remains on and the driver
indication appears, the power steering could
be faulty.
Do not continue driving. Seek specialist as-
s

istance.
 (in yellow) Steering: System fault! You
may continue driving.
If the warning lamp comes on, the steering
could react with more difficultly or more sen-
sitivity than normal. In addition, when driving
in a straight line the steering wheel may be
off-centre. Drive slowly to a specialised workshop and
have the fault repaired.
 (in yellow) Steering lock: fault! Go to an
Official Service
The electronic steering lock is malfunction-
ing.
Go to a specialised workshop as soon as
possible and have the fault repaired. WARNING
Take it immediately to a specialised work-
shop and have the fault repaired: risk of acci-
dent! Note
If the lamp  (in red) or else  (in y
ellow)
lights up briefly, you may continue driving. Progressive steering
Depending on the vehicle equipment, the
progressive steering can adapt steering hard-
ness to the current driving situation. The
power steering only works when the engine
is running.
In
city traffic
y
ou do not need to turn so much
on p
arking, manoeuvring or in very tight
turns.
On the
road or on the motorway, progressive
steering transmits, for example, in bends, a

Wheels
Depending on the vehicle, tyre pressure can
be adjusted (“comfort” tyre pressure) to in-
crease driving comfort. 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 pressures: 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 wheel alignment causes excessive
tyre wear, impairing the safety of the vehicle.
If you notice excessive tyre wear, you should
check wheel alignment at a SEAT Official
Service.
WARNING
● Always adapt the tyre pressure accordingly
when the vehicle load changes.
● A tyre with low air pressure has to flex a lot
more when the vehicle is heavily loaded or at
high speeds, therefore causing overheating
to occur. Under these conditions, the tyre
bead may be released or the tyre may burst.
Risk of accident! For the sake of the environment
Under-inflated tyres will increase fuel con-
sumption. Wear indicators
Fig. 177
Tyre tread: tread wear indicators Tread wear indicators indicate if a tyre is
worn.
The original tyres on your vehicle have
1.6 mm high “tread wear indicators” running
across the tread. Depending on the manufac-
turer, there will be 6 to 8 of them spaced at
equal distances around the tyre. Markings on
the tyre sidewall (for instance the letters
“TWI” or a triangle) indicate the positions of
the tread wear indicators.
The minimum tread depth required by law is
1.6 mm (measured in the tread grooves next
to the tread wear indicators). (Different fig-
ures may apply in other countries.)
