ification of the distance level. There are 5 dis-
tance levels to choose from. SEAT recom-
mends level 3. The set distance can be
changed when the vehicle is stopped or dur-
ing driving, as you like ››› .
C onnectin
g and activ

ating the ACC
To connect and activate the ACC, the position
of the gearbox selector lever, the vehicle
speed and the position of the third level of
the ACC must all be taken into account.
● With a manual gearbox, the gearbox selec-
tor lev
er must be in any gear except first, and
speed must be greater than approximately 30
km/h. With an automatic gearbox, the gear-
box selector lever must be in position D or S.
● To activate the ACC, with the third lever in
position 1 press the
 butt
on or mo
ve the
third lever of the ACC to position 2 ›››
Fig. 196. At thi s

point, the image of the
ACC on the instrument panel display will
switch to Active mode ››› Fig. 194. When the ACC function is active, the vehicle

Driver mes
sages
 ACC not available
The system 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: cur-
rently not available. 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 ››› Fig. 195.
 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 stability con-
trol
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

Operation
The ACC is operational as of the 2nd gear
(m anual
g
earbox).
 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,
which means exceeding or not reaching the
permissible engine speed. The ACC switches
itself off. A buzzer warning is heard.  ACC: clutch pressed
Vehicles with a manual gearbox: pressing the
clutch pedal for longer abandons control
mode. Door open
Vehicles with automatic gearbox: the ACC
cannot be activated with the vehicle station-
ary and the door open. WARNING
There is a danger of rear collision when the
minimum dis t

ance to the vehicle in front is
exceeded and the speed difference between
both vehicles is so great that a speed reduc-
tion by the ACC will not suffice. In this case
the brake pedal should be applied immedi-
ately.
● The ACC may not be able to detect all situa-
tions pr
operly.
● “Stepping” on the accelerator may cause
the ACC
not to intervene in braking. Driver braking will have priority over intervention by
the speed c
ontr

ol 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 pr ogrammed 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 122), 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. Function for preventing overtaking in

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.
220

Operation
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
› ››
Fig. 196
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 217. Driving through a bend
On entering 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 217.
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.
222

Driver assistance systems
Factors that may affect how the radar sensor
oper at
e
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
››› Fig. 195.
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 ACCnot available
remain s on for quite a long
time it means that there is a fault. Contact a
specialised 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. 223

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 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.

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
