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

Driver assistance systems
Switching off the Lane Assist system
in the following situations Due to the limits of the Lane Assist system,
switch it off in the following situations:
● When more attention is required of the
driver
● When driving in a sporty style
● In unfavourable weather conditions
● On roads in poor condition
● In areas of road works Note
The Lane Assist system deactivates when

Profile)*
Introduction 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 functions, pro-
viding different driving experiences. In the FR and X-PERIENCE models equipped
with dynamic chassis control and Navi Sys-
tem Plus, the
Comfort profile is also availa-
b l
e.
In the Leon Cupra model the four profiles are Comfort, Sport, Cupra and Individual.
The Individual profile can be configured ac-
cor

ding to personal preferences. The other
profiles are fixed.
Description Depending on the equipment fitted in the ve-
hicle, 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 Eco1)
mode activates the In- ertia function, enabling consumption to be
further reduced.
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)
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. »1)
In the Leon Cupra model, Eco mode is selected
through the Individual profile.

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
button  and the function button

ment h

as been activated.
System limitations
The Tiredness detection has certain limita-
tions inherent to the system. The following
172

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.)
