Operation
Blind spot detector (BSD) with
p ark
in
g assistance (RCTA)*
Introduction The blind spot detector (BSD) helps to detect
the traffic
s

ituation behind the vehicle.
The integrated parking assistant (RCTA) helps
the driver when backing out of a parallel
parking spot and in manoeuvring.
The blind spot detector has been developed
for driving on paved roads. WARNING
The smart technology incorporated into the
blind s pot

detector (BSD) with parking assis-
tance (RCTA) included cannot overcome the
limits imposed by the laws of physics; it only
works within the limits of the system. Acci-
dents and severe injury may occur if the blind
spot detection system or the rear cross traffic
alert are used negligently or involuntarily.
The system is not a replacement for driver
awareness.
● Adapt your speed and safe distance to the
vehicl
e in front of you at all times to suit visi-
bility, weather, road and traffic conditions.
● Keep your hands on the wheel at all times
to be re
ady to intervene in the steering at any
time.
● Pay attention to the control lamps that may
come on in the ext
ernal rear view mirrors and on the instrument panel, and follow any in-
struction
s

they may give.
● The blind spot assistant could react to any
speci
al constructions that might be present
on the sides of the vehicle: e.g. high or irreg-
ular dividers. This may cause erroneous warn-
ings.
● Never use the blind spot detector with rear
cro
ss traffic alert on unpaved roads. The blind
spot detector with rear cross traffic alert has
been designed for use on paved roads.
● Always pay attention to the vehicle's sur-
roundin
gs.
● Never use the blind spot detector or the
parkin
g assistant if the radar sensors are
dirty.
● The external rear view mirror control lamps
may
have limited functionality due to solar
radiation. CAUTION
● The ra d

ar sensors on the rear bumper may
be damaged or shifted in the event of a colli-
sion, for example, when entering or exiting a
parking space. This may result in the system
disconnecting itself, or at least possibly hav-
ing its functionality diminished.
● In order to ensure that the radar sensors
work pr
operly, keep the rear bumper free of
snow and ice and do not cover it.
● The rear bumper should only be painted
with paint
authorised by SEAT. The blind spot detector's functions may be limited or work
incorr
ectly

if other paints are used. Note
If the blind spot detector with parking assis-
t ant doe

s not work as described in this chap-
ter, do not use it and contact a specialised
workshop. Control lamps

as behind the vehicle
››› Fig. 202. The system does this by measur-
ing the vehicle's distance from other vehicles
and its speed differential. The blind spot de-
tector will not work at speeds of less than ap-
prox. 15 km/h (9 mph). The system uses opti-
cal signals in the external rear view mirrors to
notify the driver.
Indication in the external rear view mirrors
The control lamp (expanded view) provides
an indication in the corresponding external
mirror ››› Fig. 201 regarding the traffic situa-
tion behind the vehicle, if it is deemed to be
critical. The control lamp of the left-hand ex-
ternal mirror indicates the traffic situation to
the left of the vehicle, and the control lamp of
the right-hand external mirror indicates the
traffic situation to the right of the vehicle. »

Operation
In the case of retrofitted tinted windows or
w indo
w
s with tinted film, the indications of
the external mirrors may not be seen clearly
or correctly.
Keep the external mirrors clean and free of
snow and ice, and do not cover them with ad-
hesives or other similar materials.
Radar sensors
The radar sensors are located on the left and
right of the bumper and are not visible from the outside
››› Fig. 202. The sensors monitor
both the blind spot and traffic behind the ve-
hicle ››› Fig. 203, ››› Fig. 204. The range to the
sides of the vehicle is a bit larger than the
width of a lane.
The lane width is not detected individually,
but is rather pre-configured in the system.
Thus if you are driving in wide lanes or in be-
tween two lanes, the indications may be in-
correct. Furthermore, the system can detect
vehicles driving in the lane next to you (if there are any), and can also detect stationary
obj
ects such as dividers, and thus give an in-
correct indication.

ar b

umper ››› Fig. 202 to monitor the
traffic crossing behind the vehicle as it backs
out of a parallel parking space or as it is be-
ing manoeuvred, for example in very low visi-
bility conditions. If the system detects that someone else on
the roa

d is approaching the rear of the vehi-
cle ››› Fig. 205, an acoustic alarm is heard.
In addition to the acoustic alarm, if the vehi-
cle is equipped with the park assist system,
the driver is also informed by means of a vis-
ual signal on the radio screen. This signal is
displayed in the form of a red strip at the
back of the image of the vehicle on the radio
screen. This strip displays the side of the ve-
hicle towards which traffic is approaching. 1)
Automatic braking to reduce damages
If the rear cross traffic alert detects that
someone else on the road is approaching the
rear of the vehicle and the driver does not
step on the brake, the system will engage the
brakes automatically.
The parking system helps the driver by auto-
matically engaging the brakes to reduce any
damage. The system will brake automatically
if the vehicle is reversing at a speed of ap-
proximately 1-12 km (1-7 mph). Once it has
detected that the vehicle has stopped, the
system will keep the vehicle stopped for ap-
prox. 2 seconds.
After automatically braking to reduce dam-
age, the system will not be able to automati- cally brake again for approximately 10 sec-
onds.
You c
an interrupt the automatic braking by
stepping hard on the accelerator pedal or the
brake pedal in order to regain control of the
vehicle. WARNING
The smart technology incorporated into the
re ar c

ross traffic alert cannot overcome the
limits imposed by the laws of physics; it only
works within the limits of the system. The
parking assistant function should not tempt
you into taking any risks. The system is not a
replacement for driver awareness.
● The system should never be used in limited
vis
ibility conditions or complicated traffic,
e.g., in high-traffic areas or when crossing
multiple lanes.
● Be sure to always be aware of the vehicle's
surrou
ndings, since the system often fails to
detect things such as bicycles or pedestrians.
● The rear cross traffic alert itself will not
brake the
vehicle to a complete stop. 1)
It is only displayed if the vehicle is equipped with
a park in

g system.

If

the verification box on the control panel is
checked , the functionality will be automat-
ically activated at ignition.
When the blind spot detector is ready to op-
erate, the indications in the external mirrors
will turn on briefly as confirmation.
When the vehicle is restarted, the last adjust-
ment in the system will remain active.
If the blind spot detector was automatically
deactivated, it will only be possible to restart
the system after turning the vehicle off and
restarting it. Automatic deactivation of the blind spot de-
tect
or (BSD)
The r

adar sensors of the blind spot detector
with rear cross traffic alert will be automati-
cally deactivated when, among other rea-
sons, one of the sensors is detected to be
permanently covered. This may be the case if,
for example, there is a layer of snow or ice in
front of one of the sensors.
The relevant text message will appear in the
dash panel display.
Trailer mode
The Blind spot detector and the rear cross
traffic alert will be automatically deactivated
and it will be impossible to activate them if
the tow hitch is electrically connected to a
trailer or other similar object.
As soon as the driver starts to drive with a
trailer connected electrically to the vehicle, a
message will appear on the instrument panel
display indicating that the blind spot detec-
tor and the rear cross traffic alert are deacti-
vated. Once the trailer has been unhitched
from the vehicle, if you want to use the blind
spot detector and the rear cross traffic alert,
you will have to reactivate them in the corre-
sponding menu.
If the towing hitch is not factory equipped,
then the blind spot detector and the rear
cross traffic alert will have to be deactivated
manually when driving with a trailer. SEAT Drive Profile*
Introduction SEAT Drive Profile enables the driver to
choo
se betw

een four profiles or modes, Nor-
mal , Sport , Eco and Individual , that
modify the behaviour of various vehicle func-
tions, providing different driving experiences.
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. »

symbol and complementary message on the
instrument panel display ››› Fig. 208. 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 Fatigue detection h

as certain limitations
inherent to the system. The following condi-
tions can limit the Fatigue detection or pre-
vent 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
Fatigue det

ection 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. Park Assist*
Introduction The Park Assist system is an additional func-
tion of P
arkPi

lot ››› page 240 and helps the
driver to:
● find a suitable parking space,
● select a parking mode,
● park driving in reverse in suitable perpen-
dicul
ar and parallel spaces,
● park driving forwards in suitable perpen-
dicu l

ar spaces,
● exit a parking space driving forwards from
a paral
lel space.
In vehicles with a Park Assist system and fac-
tory radio the front, rear and side areas are
represented, and the position of obstacles is
shown relative to the vehicle.
The Park Assist system is subject to certain
limitations inherent to the system and its use
requires special attention by the driver ››› .
WARNING
The technology used in the park assist sys-
tem in v

olves a series of limitations inherent
in the actual system and in the use of ultra-
sonic sensors. The use of Park Assist should
never tempt you to take any risk that may 232

Driver assistance systems
compromise safety. The system is not a re-
pl
ac
ement for driver awareness.
● Any accidental movement of the vehicle
coul
d result in serious injury.
● Adapt your speed and driving style at all
times t
o suit visibility, weather, road and traf-
fic conditions.
● Certain surfaces of objects and garments
do not refl
ect the ultrasound sensors' sig-
nals. The system cannot detect, at least cor-
rectly, these objects or people wearing such
clothes.
● Ultrasound sensor signals may be affected
by e
xternal sound sources. In certain circum-
stances this may prevent them from detect-
ing people or objects.
● The ultrasound sensors have blind spots in
which ob
stacles and people are not regis-
tered.
● Monitor the area around the vehicle at all
times, sinc
e the ultrasound sensors do not
detect small children, animals or certain ob-
jects in all situations. WARNING
Quick turns of the steering wheel when park-
ing or e x

iting a parking space with Park As-
sist can cause serious injury.
● Do not hold the steering wheel during ma-
noeuvre
s to park or exit a parking space until
the system requests it. Doing so disables the
system during the manoeuvre, resulting in
the parking being cancelled. CAUTION
● In cer t

ain circumstances, the ultrasonic
sensors do not detect objects such as trailer
tongues, bars, fences, posts or thin trees, or
an open (or opening) rear lid, which could
damage the vehicle.
● Retrofitting of certain accessories to the ve-
hicle, s
uch as a bicycle rack, may interfere
with the operation of the Park Assist system
and cause damage.
● The Park Assist system uses as a reference
parked
vehicles, curbs and other objects.
Make sure that the tyres and wheels are not
damaged while parking. If necessary, oppor-
tunely interrupt the parking manoeuvre to
avoid damaging the vehicle.
● The ultrasound sensors on the bumper may
be damag
ed or shifted in the event of a colli-
sion, for example, when entering or exiting a
parking space.
● If you use high-pressure or vapour equip-
ment to c
lean the ultrasound sensors, do not
apply it directly unless very briefly and al-
ways from a distance of more than 10 cm.
● A registration plate or plate holder on the
front w
ith larger than the space for the regis-
tration plate, or a registration plate that is
curved or warped can cause:
–false detections,
– loss of sensor visibility.
– cancellation of the parking manoeuvre or
defective parking. ●
If one of the u

ltrasonic sensors is damaged,
the area corresponding to that group of sen-
sors (front or rear) is deactivated and cannot
be activated until the fault is corrected. How-
ever, you can still use the sensors of the oth-
er bumper as per usual. If there is a fault in
the system, consult a specialist workshop.
SEAT recommends visiting a SEAT dealership
for this. Note
● In or der t o guar

antee good system opera-
tion, keep the ultrasound sensors of the
bumper clean, free of snow or ice, and do not
cover them with adhesives or other objects.
● Certain sources of noise, such as rough as-
phalt
or paving stones and the noise of other
vehicles can induce the Park Assist system or
ParkPilot to give erroneous warnings.
● In order to become familiar with the system
and its f
unctions, SEAT recommends that you
practice operating the Park Assist system in
an area where there is not too much traffic or
in a car park. 233

Prematurely stopping or automatically inter-
rupting the manoeuvres for parking or exit-
ing a parking space
Park Assist interrupts the manoeuvres for
parking or exiting a parking space in any of
the following cases:
● Press the  button. ●
The s
peed ex

ceeds approximately 7 km/h
(4 mph).
● The driver takes hold of the steering wheel.
● The parking manoeuvre does not end with-
in appro
ximately 6 minutes following activa-
tion of the automatic steering.
● There is a fault in the system (the system is
temporari
ly unavailable).
● ASR is switched off.
● ASR or ESC intervene with regulation.
● The driver door is opened.
To re
start the manoeuvre it is necessary that
none of these things occur and that the 
button is pressed again.
Special Characteristics
The Park Assist system is subject to certain
limitations inherent to the system. For exam-
ple, it is therefore not possible to enter or exit
a parking space on sharp bends.
While entering or exiting a parking space, a
brief signal sounds to prompt the driver to
change between forward and reverse gears
(depending on the case). In successive ma-
noeuvres, the assistant tells the driver to
change gears, at the latest, when the contin- uous audible signal is given (object present
at a dis

tance of ≤30 cm) by Park Pilot.
When the Park Assist system turns the steer-
ing wheel with the vehicle stationary, the in-
strument panel also displays the symbol .
Keep the brake pedal depressed while the
symbol remains on the dash panel display to
turn the wheels with the vehicle stopped.
This way, the system will require fewer ma-
noeuvres to complete the parking action.
Trailer mode
The Park Assist system cannot be switched
on if the factory-fitted towing bracket
››› page 249 is electrically connected to a
trailer.
After changing a wheel
If, after changing a wheel, the vehicle stops
entering and exiting parking spaces correctly,
the circumference of the new wheel may be
different and the system may need to adapt
to it. The adaptation is automatic and takes
place during driving. Making turns slowly and
in both directions (20 km/h [12 mph]) for a
few minutes may contribute to this adapta-
tion process ››› in Introduction on
