The pedestrian monitoring system, including
the a dv
ance warning, is automatically con-
nected when the ignition is switched on
››› page 165.
SEAT recommends always having the pedes-
trian monitoring system connected. The ex-
ceptions set out for the Front Assist system
are equally valid for the pedestrian monitor-
ing system ››› page 210.
Switching the pedestrian monitoring system
on and off
With the ignition on, the pedestrian monitor-
ing system can be switched on and off as fol-
lows:
● Switch the system on and off in the info-
tainment

When the pedestrian protection system is
switched off, the dash panel display shows a
message indicating this ››› Fig. 188 . The
pedestrian monitoring system is switched off
with the Front Assist function. WARNING
The technology in the pedestrian monitoring
sy s

tem cannot defy the laws of physics and
only works within the system's limits. The
driver is always responsible for braking in
time. If the pedestrian monitoring system is- sues a warning, brake the vehicle immediate-
ly
w

ith the brake pedal or swerve to avoid the
pedestrian, depending on traffic conditions.
● The pedestrian monitoring system alone
cannot
avoid accidents or serious injury.
● In complex driving situations, the pedes-
trian monit
oring system may issue unneces-
sary warnings and intervene unnecessarily in
braking, such as in main roads with turnings.
● If the operation of the system is impaired,
for e
xample, because the radar sensor and
camera are covered or have lost their set-
tings, the system may issue unnecessary
warnings and intervene inopportunely in the
braking.
● The driver must always be ready to take
ov
er the control of the vehicle. Note
● When the v

ehicle is braked via the pedes-
trian monitoring system, the brake pedal be-
comes stiffer.
● Automatic interventions by the pedestrian
monitorin
g system on the brakes may be in-
terrupted by pressing the accelerator or mov-
ing the wheel.
● If the pedestrian monitoring system does
not w
ork as described in this chapter (e.g. if
it intervening unnecessarily several times),
switch if off, contact a specialist workshop
immediately and request to have the system
checked. SEAT recommends visiting a SEAT
dealership for this. Lane Assist system*
Intr oduction WARNING
The intelligent technology in the Lane Assist
sy s

tem 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
ro

ad 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-
rou
ndings.
● When the area of vision of the camera be-
come
s dirty, covered or is damaged, the Lane
Assist system function can be affected. » 213

en into account:
● Regularly clean the area of vision of the
camer
a and keep it in a clean state, without
snow or ice.
● Do not cover the area of vision of the cam-
era.
● Chec

k that the area of vision of the wind-
sc
reen camera is not damaged. Note
● The Lane As s

ist system has been exclusive-
ly developed for driving on paved roads only.
● If the Lane Assist system does not work as
des
cribed in this chapter, do not use it and

Operation Fig. 191
In the windscreen: field of vision of
the Lane As s

ist system camera. Using the camera located in the windscreen,
the Lane As
s

ist 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 . This 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 can 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
sys
tem are reached. ●
When the max
imum 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 s
teering movement.

wheel intervention. This occurs even if the
turn signal is activated in the corresponding
direction. If the driver over-regulates the
steering wheel intervention, an additional
warning is given through a vibration in the
steering wheel. Note
● Bef

Blind spot detector (BSD) with
p ark
ing assistance (RCTA)*
Introduction 

› ›
›
table on page 2
The blind spot detector (BSD) helps to detect
the traffic situation behind the vehicle.
The integrated parking assistant (RTA) 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
b lind 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
vehic
le 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 r
eady to intervene in the steering at any
time. ●
Pa

y attention to the control lamps that may
come on in the external rear view mirrors and
on the instrument panel, and follow any in-
structions they may give.
● The blind spot assistant could react to any
spec
ial 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
cr

oss 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-
rou
ndings.
● Never use the blind spot detector or the
park
ing assistant if the radar sensors are
dirty.
● The external rear view mirror control lamps
ma
y have limited functionality due to solar
radiation. CAUTION
● The r a

dar 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
properly, keep the rear bumper free of
snow and ice and do not cover it. ●
The r e

ar 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. Note
If the blind spot detector with parking assis-
t ant

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

The faster the vehicle approaches, the sooner
an indication will be displayed in the external

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 sit
uations the blind spot detector
may not interpret the traffic situation correct-

● in the case of lanes with different widths;
● at the top of slopes;
● in adverse weather conditions; »

Parking assistant (RTA) Fig. 196
Schematic representation of the rear
c r

oss traffic alert: monitored zone around the
vehicle being parked. The parking assistant uses the radar sensors
on the r
e

ar bumper ››› Fig. 193 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 road is approaching the rear of the vehi-
cle ››› Fig. 196, an acoustic alarm is heard. ●
The acou
stic alarm comes from the same
acoustic indicator used by the ParkPilot.
In addition to the acoustic alarm, the driver is
also informed by means of a visual signal on
the radio screen. This signal is displayed in
the form of a red strip at the back of the im-
age of the vehicle on the radio screen. This
strip displays the side of the vehicle towards
which traffic is approaching.
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 hard on the accelerator pedal or the
brake pedal in order to regain control of the
vehicle. WARNING
The smart technology incorporated into the
r e

ar cross 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
vi

sibility 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
surr
oundings, since the system often fails to
detect things such as bicycles or pedestrians.
● The rear cross traffic alert itself will not
brak
