In the windscreen: field of vision of
the l ane a
s

sist system camera. Using the camera located in the sun visor,
the l
ane a
s

sist system detects the possible
lines dividing it. When the vehicle involuntar-
ily approaches a dividing line it has detected,
the system will notify the driver with a correc-
tive intervention. It is possible to over-regu-
late the corrective intervention at any time.
If the turn signal is connected, there will be
no warning as the lane assist system under-
stands that you wish to change lanes volun-
tarily. Steering wheel vibration
The fol

lowing situations cause the steering
wheel to vibrate and require the driver to take
active control of the steering:
● If the limits inherent to the system are
reac
hed.
● If the maximum rotational torque during
the correctiv
e intervention is not enough to
keep the vehicle inside the lane.
● If during the corrective intervention by the
syst
em the lane is no longer detected.

Driver assistance systems
Blind spot detector (BSD) with
r e
ar c
ross traffic alert (RCTA)
Related video Fig. 220
Blind Spot De-
tector (BSD) Introduction
The blind spot detector (BSD) helps detect
the tr
affic
s

ituation to the sides and 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
al
er

t 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,
and be rea
dy 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-
structions they may give.
● The blind spot assistant may react in the
face of
any special constructions that may be
present on the sides of the vehicle: e.g., high
or irregular protective fences. This may cause
erroneous warnings.
● 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 with rear
cro
ss traffic alert if the radar sensors are
dirty, covered or damaged. The system may
work incorrectly in these cases. 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
park
in

g space. This may result in the system
disconnecting itself, or at least having 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
incorrectly if other paints are used.
● The external rear view mirror control lamps
may
have their functionality limited in the
event of solar radiation. Note
If the blind spot detector with rear cross traf-
fic a l

ert does not work as described in this
chapter, do not use it and have it checked by
a specialised workshop. Control lamps

Operation
Flashes
The blind spot detector has detected a vehicle in the
blind spot and the turn signal has been turned on in the
direction of the detected vehicle
›››
.
For vehicles that are also equipped with Lane Assist
››› page 222, a warning to switch lanes will also appear
even though the turn signal has not been engaged. If there are no indications from the control
lamp in the e
xt

ernal rear view mirror, this
means that the blind spot detector has not
detected any other vehicles in the area ››› in Introduction on page 225.
If
the dip
ped be

am is on, then the control
lamps in the external rear view mirrors will be
dimmed (night mode). WARNING
If the warning lamps and the corresponding
mes s

ages are ignored when they light up, the
vehicle may stall in traffic and cause acci-
dents and severe injuries.
● Never ignore the warning lamps or messag-
es.
● Carr

y out the necessary operations. CAUTION
Failure to heed the control lamps and corre-
spondin g t

ext messages when they light up
may result in damage to the vehicle. Blind spot detector (BSD)

Rear view of the vehicle: radar sen-
sor z one

s. The Blind spot detector uses radar sensors to
monit
or the ar
e

as to the side and behind the
vehicle. The system does this by measuring
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. 221 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 A indicates the traffic situation
to the left of the vehicle, and the control lamp
of the right-hand external mirror B, indicates
the traffic situation to the right of the vehicle.
226

Driver assistance systems
In the case of tinted windows or windows
w ith tint
ed fi
lm, the indications of the exter-
nal mirrors may not be seen clearly or correct-
ly.
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 sensor are located on the left and
right of the bumper, and are not visible from the outside
››› Fig. 222. The sensors have a
range of approx. 20 metres behind the vehi-
cle, including the blind spots to the left and
right of the vehicle. The range to the sides of
the vehicle is roughly 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 an
y), and can also detect stationary
objects such as dividers, and thus give an in-
correct indication.

with a speed differential of approx. 10 km/h
(6 mph). If the vehicle is passing at a consid- erably higher speed, no indication will be
disp

layed.
The faster the vehicle approaches, the sooner
an indication will be displayed in the external
mirror, because the blind spot detector takes
into account the speed differential with other
vehicles. Thus even though the distance from
the other vehicle is identical, the indication
will appear sooner in some cases and later in
others. Physical limitations inherent to the system
In some situation
s the blind spot detector
may not interpret the traffic situation correct-
ly. E.g. in the following situations:
● on tight bends
● in the case of lanes with different widths
● at the top of slopes
● in adverse weather conditions

on the r

ear bumper ››› Fig. 222 to moni-
tor the traffic crossing behind the vehicle as
it backs out of a perpendicular parking space
or as it is being manoeuvred, for example in
very low visibility conditions.
If the system detects that someone else on
the road is approaching the rear of the vehi-
cle ››› Fig. 225, an acoustic alarm will sound. ●
In vehic
les without ParkPilot a “gong” will
sound and a message will be displayed on
the instrument panel.
● If the vehicle is equipped ParkPilot, the
ParkPilot
acoustic alarm will sound continu-
ously.
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 can interrupt the automatic braking by
stepping forcefully 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. Do not
let the extra convenience afforded by the rear
cross traffic alert 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 is not guaran-
teed to detect things such as bicycles or pe-
destrians in all situations.
● The rear cross traffic alert itself will not
brake the
vehicle to a complete stop. Using the blind spot detector (BSD)

Operation
●  BSD
●  P arking Assist.
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.
The control lamp of the instrument panel in-
dicates the system's status.
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-
tector (BSD)
The radar 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 det

ector 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.
