Driver assistance systems
Radar sensor Fig. 159
On the front bumper: radar sensor. A radar sensor is installed on the front bump-
er to determine the traffic situation
››› Fig. 159 1 . This sensor can detect vehi-
cles in front up to a distance of approximately
120 m.
The radar sensor's visibility may be impaired
by dirt, mud or snow, or by environmental in-
fluences such as rain or mist. In this case the
Front Assist monitoring system does not
work. The instrument panel displays the fol-
lowing message: Front Assist: No sensor vi- sion! If necessary clean the radar sensor ››› .
When the radar sensor begins to operate
properly again, the Front Assist will automati-
cally be available again. The message will
disappear from the instrument panel display.
Front Assist operation may be affected by a
strong radar reverse reflection. This may oc-
cur, for example, in a closed car park or due to the presence of metallic objects (e.g. rails
on the road or sheets used in road works).
The area in front of and around the radar sen-
sor should not be covered with adhesives,
additional or similar headlights, as this may
negatively affect Front Assist operation.
If structural modifications are made to the ve-
hicle, for example, if the suspension is low-
ered or the front spoiler is modified, Front As-
sist operation may be affected. So structural
modifications should only be made by speci-
alised workshops. SEAT recommends visiting
a SEAT dealership for this purpose.
If work is done incorrectly on the front of the
vehicle, the radar sensor could be damaged
or lose its settings, and Front Assist opera-
tion may be affected. So repair work should
only be made by specialised workshops.
SEAT recommends visiting a SEAT dealership
for this purpose.
CAUTION
If you have the sensation that the radar sen-
sor is damaged or has lost its settings, dis-
connect the Front Assist. This will avoid pos-
sible damage. If this occurs have it adjusted. ● The sensor may become damaged or lose
its settings when knocked, for example, dur-
ing a parking manoeuvre. This may compro-
mise the system's efficacy or disconnect it.
● Repairs to the radar sensor require special-
ist knowledge and special tools. SEAT recom- mends visiting a SEAT dealership for this pur-
pose.
● Clean away the snow with a brush and the
ice preferably with a solvent-free de-icer
spray. Operating the Front Assist monitoring

Switching the Front Assist Monitoring
System off in the following situations In the following situations the Front Assist
Monitoring System should be deactivated
due to the system's limitations
››› :
● When the vehicle is to be towed.
● If the vehicle is on a test bed.
● When the radar sensor is damaged.
● If the radar sensor takes a heavy knock, for
example in a rear collision.
● If it intervenes several times unnecessarily.
● If the radar sensor is covered temporarily
with some kind of accessory, such as an ad-
ditional headlight or the like.
● When the vehicle is to be loaded on a lorry,
ferry or train. WARNING
If the Front Assist is not switched off in the
situations described, serious accidents and
injuries may occur.
● Switch off the Front Assist in critical situa-
tions. System limitations
The Front Assist Monitoring System has cer-
tain physical limitations inherent in the sys-
tem. Thus, in certain circumstances some of
the system's reactions may be inopportune
or be delayed from the driver's standpoint.
So pay attention in order to intervene if nec-
essary.
The following conditions may cause the Front
Assist Monitoring System not to react or do
so too late:
● On taking tight bends.
● Pressing the accelerator all the way down.
● If the Front Assist is switched off or dam-
aged.
● If the ASR has been manually disconnec-
ted.
● If the ESC is controlling.
● If several brake lights of the vehicle or elec-
trically connected trailer are damaged.
● If the radar sensor is dirty or covered.
164

Driver assistance systems
● If there are metal objects, e.g. rails on the
road or sheets used in road works.
● If the vehicle is reversing.
● If the vehicle over-accelerates.
● In case of snow or heavy rain.
● In case of narrow vehicles, such as motor-
bikes.
● Misaligned vehicles.
● Vehicles crossing the other's path.
● Vehicles approaching in the opposite direc-
tion.
● Special loads and accessories of other ve-
hicles that jut out over the sides, backwards
or over the top. City Emergency braking function Fig. 161
On the instrument panel display:
pre-warning message The City Emergency braking function is part
of the Front Assist monitoring and is active
whenever the system is switched on.
Depending on the equipment, the pre-warn-
ing function can be switched on or off in the
Easy Connect system with the button
 and
the function buttons  and
Driver Assist ›››
 page 17
.
The C ity
Emergency braking function picks
up, at speeds between 5 km/h (3 mph) and
30 km/h (19 mph) approximately, the traffic
situation in front of the vehicle up to a dis-
tance of about 10 m. If the system detects a possible collision with
a vehicle in front of it, the vehicle prepares
for a possible emergency braking
››› .
If the driver fails to react to a possible colli-
sion, the system may brake the vehicle auto-
matically, by progressively increasing braking
effect driving to reduce speed in the event of
a collision. The system can thus help to re-
duce the consequences of an accident.
Status display
Automatic deceleration by means of the City
Emergency braking function is displayed on
the instrument panel by means of the pre-
warning ››› Fig. 161 1)
. WARNING
The smart technology included in the City
Emergency braking function cannot defy the
laws of physics. The driver is always respon-
sible for braking in time.
● Adapt your speed and safe distance to the
vehicle in front of you at all times to suit visi-
bility, weather, road and traffic conditions.
● The City Emergency braking function alone
cannot prevent accidents or serious injury.
● In complex driving situations, the City
Emergency braking function may issue unnec-
essary warnings and intervene inopportunely »1)

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)

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

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

Driver assistance systems
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
Tiredness detection will be restored when the
vehicle 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 parking or manoeuvring in tight spaces, depending on the equipment fitted
on your vehicle.
The
rear parking aid
is an audible assistant
th
at warns about obstacles located behind
the vehicle ››› page 174.
Durin

g parking, the
parking system plus as-
sists you visually and audibly about obsta-
cles detected in front and behind
the vehicle
››› page 174. WARNING
● Always pay attention, also when looking
straight ahead, to traffic and the vehicle sur-
roundings. The assistance systems are not a
replacement for driver awareness. When in-
serting or removing the vehicle from a park-
ing space, or when performing similar ma-
noeuvres the driver always assumes the re-
sponsibility.
● Take into account that the system is not al-
ways in conditions to recognise or represent
certain surfaces, such as dress fabric: Risk of
causing an accident!
● The sensors and cameras have blind spots,
making the detection of people and objects
impossible. Pay special attention to children
and animals: Risk of causing an accident!
● Always keep visual control of the vehicle
surroundings: use the rear vision mirrors for
additional help. CAUTION
● Under certain circumstances, the system
does not detect or display certain objects:
– Objects such as snow chains, trailer draw
bars, bars or fences.
– Objects that are located above the sen-
sors, such as protrusions in a wall.
– Objects with certain surfaces or struc-
tures, such as wire mesh fences or pow-
der snow.
● Please note that low obstacles detected by
the system may no longer be registered by
the sensors as the car moves closer, so the
system will not give any further warning. In
certain circumstances, objects such as high kerbs that could damage the bottom of the
vehicle are not detected either.
● If the first warning from the Park Pilot is ig-
nored, the vehicle could suffer considerable
damage.
● The knocks or damage on the radiator
grille, bumper, wheel arch and vehicle under-
body can adjust the orientation of the sen-
sors. This can affect the parking aid function.
Have the function checked by a specialised
workshop. Note
● In certain situations, the system can give a
warning even though there is no obstacle in
the detected area, e.g: » 173

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. »
