Driver assistance systems
●
The AC C
may not be able to detect all situa-
tions properly.
● “Stepping” on the accelerator may cause
the ACC
not to intervene in braking. Driver
braking will have priority over intervention by
the speed control or adaptive cruise control.
● Always be ready to use the brakes!
● Observe country-specific provisions gov-
erning ob
ligatory minimum distances be-
tween vehicles.
● It is dangerous to activate control and re-
sume the progr
ammed speed if the road, traf-
fic or weather conditions do not permit this.
Risk of accident! Note
● The progr ammed s

peed is erased once the
ignition or the ACC are switched off.
● When the traction control system (ASR) is
deactivat
ed during acceleration or else the
ESC is activated in Sport* Mode
( ››› page 118), the ACC switches off automati-
cally.
● In vehicles with the Start-Stop system, the
engine swit
ches off automatically during the
ACC stopping phase and restarts automatical-
ly to begin driving. Driver messages
 ACC not available
The sy s

tem can no longer continue to guar-
antee safe vehicle detection and will be de-
activated. The sensor has lost its setting or is
damaged. Take the vehicle to a specialised
workshop and have the fault repaired.
 ACC and Front Assist: currently not availa-
ble. No sensor vision
This message will be displayed to the driver if
the radar sensor's vision is impaired due, for
example, to leaves, snow, heavy fog or dirt.
Clean the sensor.
 ACC: currently not available. Gradient too
steep
The maximum road slope has been excee-
ded, hence safe ACC operation cannot be
guaranteed. The ACC cannot be switched on.
 ACC: only available in D, S or M
Select the D/S or M position on the selector
lever.
 ACC: parking brake applied
The ACC is deactivated if the parking brake is
applied. The ACC is available once again after
the parking brake is released.  ACC: currently not available. Intervention
of
s

tability control
The message for the driver is displayed when
the electronic stability control (ESC) inter-
venes. In this case, the ACC is automatically
switched off.
 ACC: Take action!
The message for the driver is displayed if,
when the vehicle starts up on a hill with a
mild slope, the vehicle rolls back even al-
though the ACC is activated. Apply the brake
to stop the vehicle from moving/colliding
with another vehicle.
 ACC: speed limit
The message for the driver is displayed if, in
vehicles with manual gearbox, the current
speed is too low for the ACC mode.
The speed to be stored must be at least
30 km/h (18 mph). The speed limiter
switches off if the speed falls below 20 km/h
(12 mph).
 ACC: available as of the 2nd gear
The ACC is operational as of the 2nd gear
(manual gearbox).
 ACC: engine speed
The message for the driver is displayed if,
when the ACC accelerates or brakes, the driv-
er does not shift up or down a gear in time, »

active, vehicle detected in an outer lane. The adaptive cruise control (ACC) has a func-
tion th
at
help

s avoid overtaking while driving
in inside lanes at certain speeds.
If another vehicle is detected travelling at a
slower speed in an outer lane, it is displayed
on the multifunction display ››› Fig. 198.
To avoid overtaking while driving in an inside
lane the system will gently brake, and in ac-
cordance with the speed will prevent the car
from overtaking. The driver can override this
function at any time by pressing the accelera-
tor pedal. At low speeds the function is inac-
tive, for greater comfort in a traffic jam or in
city traffic.
Deactivating the Adaptive Cruise Con-
trol
ACC temporarily in certain situa-
tions In the following situations the Adaptive
C
rui
se C

ontrol (ACC) should be deactivated
due to the system's limitations ››› :
● When changing lanes, on tight bends and
r ou
nd

abouts, in acceleration and decelera-
tion lanes on motorways or in sections with
road works to prevent involuntary accelera-
tion to reach the programmed speed.
● When going through a tunnel, as operation
coul
d be affected.
● On roads with several lanes, when other ve-
hicle
s are driving more slowly in the overtak- ing lane. In this case, slower vehicles will be
over

taken on the right.
● In case of heavy rain, snow or spray, as the
vehicl
e in front might not be detected proper-
ly or, in certain circumstances, might not be
detected at all. WARNING
If the ACC does not switch off in the situa-
tions de

scribed, serious accidents and inju-
ries may occur.
● Always switch off the ACC in critical situa-
tions. Note
If you do not switch off the ACC in the afore-
mentioned sit uation

s, you may commit a le-
gal offence. 216

ph
y
s

ical limitations inherent in the system.
For example, certain reactions of the ACC, in
certain circumstances, may be unexpected or
come late from the driver's point of view. So
pay attention in order to intervene if necessa-
ry.
For example, the following traffic situations
call for the utmost attention:
Starting driving after a stopping phase (only
vehicles with automatic gearbox)
After a stopping phase, the ACC may begin
driving automatically when the vehicle in
front drives off ››› .When the ACC halts the vehicle (e.g. traffic
j
am), the in
s

trument panel display shows the
ACC ready to start message. If the ve-
hicle ahead drives off again, the ACC will also
do so automatically.
If the vehicle ahead does not drive off again,
the vehicle can be kept indefinitely in the
ACC ready to start status by operating
the third lever repeatedly towards position 2

or b
y pressing the brake pedal.
If the Press the brake message is shown
on the instrument panel, press the brake. If
you do not, an acoustic warning will be heard
and the ACC will switch to inactive mode
(Standby). At this point, the vehicle may be-
gin to move towards the stopped vehicle
ahead ››› .
Ov er
t

aking
When the turn signal lights up before the ve-
hicle begins an overtaking manoeuvre, the
ACC accelerates the vehicle automatically
and thus reduces the distance from the vehi-
cle in front.
When the vehicle enters the overtaking lane,
if the ACC does not detect another vehicle in
front, it accelerates until it reaches the pro-
grammed speed and maintains it.
System acceleration can be interrupted at
any time by pressing the brake or moving the
third lever backwards ››› page 213. »

Operation
Driving through a bend
On ent erin
g or e
xiting bends, the radar sen-
sor may no longer determine the vehicle in
front or react to a vehicle in the adjacent lane
››› Fig. 199 A. In these situations the vehicle
may brake unnecessarily or fail to react to re-
act to the vehicle in front. In this case, the
driver has to intervene by accelerating or in-
terrupting the braking process by applying
the brake or pushing the third lever back-
wards ››› page 213.
Driving in tunnels
When driving through tunnels the radar sen-
sor may be limited. Switch off the ACC in tun-
nels.
Narrow or misaligned vehicles
The radar sensor can only detect narrow or
misaligned vehicles when they are within
range ››› Fig. 199 B. This applies particularly
to narrow vehicles such as motorbikes. In
these cases, you should brake as necessary.
Vehicles with special loads and accessories
Special loads and accessories of other vehi-
cles that jut out over the sides, backwards or
over the top may be out of the ACC's range.
Switch off the ACC when driving behind vehi-
cles with special loads and accessories or
when overtaking them. In these cases, you
should brake as necessary. Other vehicles changing lanes
Vehicl
es changing lanes a short distance
away from your own can only be detected
when they are within range of the sensors.
Consequently, the ACC will take longer to re-
act ››› Fig. 200 C. In these cases, you should
brake as necessary.
Stationary vehicles
The ACC does not detect stationary objects
while driving, such as traffic tails or damaged
vehicles.
If a vehicle detected by the ACC turns or
moves over and there is a stationary vehicle
in front of it, the ACC will not react to it
››› Fig. 200 D. In these cases, you should
brake as necessary.
Vehicles driving in the opposite direction
and vehicles crossing your path
The ACC does not react to vehicles approach-
ing from the opposite direction or vehicles
crossing your path.
Metal objects
Metal objects, e.g. rails on the road or sheets
used in road works, can confuse the radar
sensor and cause the ACC to react wrongly. Factors that may affect how the radar sensor
operate
s
If laser sensor operation is impaired, due to
heavy rain, spray, snow or mud, the ACC is
deactivated temporarily. The relevant text
message will appear in the dash panel dis-
play. If necessary, clean the radar sensor.
When the radar sensor begins to operate
properly again, the ACC will automatically be
available again. The message on the instru-
ment panel screen will switch off and the ACC
will be reactivated again.
ACC operation may be affected by a strong ra-
dar reverse reflection, for example in a closed
car park.
Trailer mode
When driving with trailer the ACC controls
less dynamically.
Overheated brakes
If the brakes overheat, for example after
abrupt braking or in long and steep slopes,
the ACC may be deactivated temporarily. The
relevant text message will appear in the dash
panel display. In this case, adaptive cruise
control cannot be activated.
Adaptive cruise control can be reactivated
once brake temperature has cooled suffi-
ciently. The message will disappear from the
instrument panel display. If the message ACC
not available remains on for quite a long
218

time it means that there is a fault. Contact a
s pec
i
alised workshop. SEAT recommends vis-
iting a SEAT dealership. WARNING
If you do not heed the Press the brake
mes s

age, the vehicle may initiate an involun-
tary movement and could crash into the vehi-
cle ahead. In any event, before driving off,
check that the road is clear. The radar sensor
may not detect obstacles on the road. This
could cause an accident and serious injuries.
If necessary, apply the brake. 219Technical data

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

ed an
y other vehicles in the area ››› .
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)

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

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.
