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

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

Parking assistant (RCTA) Fig. 205
Schematic representation of the rear
c r

ss traffic alert: zone monitored around the
vehicle exiting the parking space. The parking assistant uses the radar sensors
on the r
e
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 road 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 i

s 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.
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
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

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: ●
Button  is pressed.
● The speed exceeds approximately 7 km/h
(4 mph).
● The driver takes hold of the steering wheel.
● The parking manoeuvre does not end with-
in ap pr
o

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 button  is pressed again.

al 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. If
this signal does not sound, the gear change will be indicated when the continuous signal
sounds

(object at 30 cm) in ParkPilot.
When the Park Assist system turns the steer-
ing wheel with the vehicle stationary, the in-
strument panel also displays the symbol .
Press down the brake pedal so that the turn
takes place with the vehicle stationary and
the smallest possible number of manoeuvres
take place in the parking space.
Trailer mode
The Park Assist system cannot be switched
on if the factory-fitted towing bracket
››› page 245 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, at
less than 20 km/h (12 mph) may contribute
to this adaptation process ››› in Introduc-

Autom atic

braking intervention to avoid ex-
ceeding the speed limit
To avoid exceeding the speed limit of approx-
imately 7 km/h (4 mph) when entering or
leaving a parking space, the brakes may acti-
vate automatically. After automatically acti-
vating the brakes, the manoeuvres to enter or
exit a parking space may continue.
The brakes are only automatically activated
once for each attempt to enter or exit a park-
ing space. If the speed of approximately
7 km/h (4 mph) is exceeded again, the corre-
sponding operation is halted.
Automatic braking to reduce damages
Depending on certain conditions, the Park
Assist system can automatically brake the ve-
hicle when faced with an obstacle, briefly ac-
tioning and holding down the brake ped-
al ››› . Following this the driver must press
the br ak
e ped

is not a replacement for driver awareness.
● The Park Assist system is subject to certain
limitations
inherent to the system. In certain
situations, the automatic braking interven-
tion may only work in a limited way or not

● Alw a

ys 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.
● Adapt your speed and driving style at all
times t
o suit visibility, weather, road and traf-
fic conditions.
● The ultrasound sensors have blind spots in
which ob
stacles and people are not regis-
tered. Pay special attention to children and
animals.
● Always keep visual control of the vehicle

ndings: use the mirrors for additional
help. CAUTION
Parking Aid functions may be negatively af-
fect ed b

y different factors that may lead to
damage to the vehicle or its immediate sur-
rounds:
● Under certain circumstances, the system
does not
detect or display certain objects:
– Objects such as chains, trailer draw bars,
fences, posts and thin trees.
– Objects that are located above the sen-
sors, such as protrusions in a wall. 236

Braking while manoeuvring function* 3 Only
valid with Parking System Plus
The emer
gency braking function is used to
minimise damage in the event of a collision.
Depending on the equipment, if the Parking
Aid is active, the braking while manoeuvring
function activates emergency braking when it
detects an obstacle in the vehicle’s path that
could cause a collision, driving forwards or in
reverse.
The function will not brake if the Parking Aid
is activated automatically. For the system to
operate, manoeuvring speed must be greater
than 2.5 km/h and less than 10 km/h.
Following an intervention, the braking while
manoeuvring function will be inactive in the same direction of travel for 5 metres. Once
the ge
ar i

s changed, or the selector lever’s
position is changed, the function will be ac-
tive again. The Parking Aid’s limitations ap-
ply.
The braking while manoeuvring function is
controlled in the Easy Connect system with
the  menu and the
S
