 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 AC
C 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
gear The ACC is operational as of the 2nd gear
(manual 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

Operation
Note
If you do not switch off the ACC in the afore-
mentioned sit uation
s, you may commit a le-
gal offence. Special driving situations

e turning and another stationary. The adaptive cruise control (ACC) has certain
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 224.

Driver assistance systems
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. 200 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 224.
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. 200 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. 201 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. 201 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 SEAT
badge ››› Fig. 196.
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»

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

st 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 . The purpose
is not only to warn the driver, but also to
keep the vehicle inside the lane. 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. Indications on the display and lamps Fig. 203

Driver assistance systems
Operation of Emergency Assist
Emer g
ency
Assist detects when the driver
ceases to perform any activity and repeatedly
requests that he/she regain active control of
the vehicle, through the use of optical and
acoustic warnings and by applying the
brakes.
If the driver continues to do nothing, the sys-
tem automatically takes over the accelerator,
brakes and steering in order to brake the ve-
hicle and keep it in its lane ››› . When the
Emer g
ency

Assist is actively adjusting, the
hazard warning lights come on ››› page 149
and the vehicle makes slight zigzag move-
ments in the lane in order to warn other driv-
ers.
If the remaining braking distance is suffi-
cient, if necessary the system slows down the
vehicle until it stops completely and auto-
matically switches on the electronic parking
brake ››› page 186.
Switching the Emergency Assist on and off
The Emergency Assist is switched on auto-
matically when the Lane Assist is switched on
››› page 230.
Technical requirements for using the Emer-
gency Assist ● The adaptive cruise control (ACC) must be
switc
hed on ››› page 221. ●
The Lane Assi
st must be switched on
››› page 230.
● The selector lever must be in the D/S posi-
tion or in the
Tiptronic selector gate.
● The system must have detected a lane sep-
aration line on both side
s of the vehicle
››› Fig. 204.
The following conditions may cause the
Emergency Assist not to react or to switch off
automatically:
● If the driver accelerates, brakes or moves
the steerin
g wheel.
● If any of the conditions mentioned in
›››
page 235, Technical requirements for us-
ing the Emergency Assist are not fulfilled.
● If any of the conditions required for opera-
tion of the Lane Ass
ist are not met
››› page 230.
● If any of the conditions necessary for the
adaptiv
e cruise control (ACC) to work are no
longer fulfilled ››› page 221. WARNING
The smart technology incorporated into the
Emerg ency

Assist cannot overcome the limits
imposed by the laws of physics; it only works
within the limits of the system. The driver is
responsible for driving the vehicle.
● Adapt your speed and safe distance to the
vehicl
e in front of you at all times to suit the visibility, weather, road and traffic condi-
tions.
● Keep

your hands on the wheel at all times
to be re
ady to intervene in the steering at any
time.
● The Emergency Assist alone cannot always
avoid acc
idents or serious injuries.
● If the operation of the Emergency Assist is
impaired, f
or example if the radar sensor of
the adaptive cruise control (ACC) or the Lane
Assist camera are covered or have lost their
settings, the system may intervene inoppor-
tunely in braking or in steering.
● The Emergency Assist does not react to
people or anim
al or vehicles crossing your
path or which approach you head-on in the
same lane. WARNING
If the Emergency Assist Intervenes inoppor-
tu nely

, serious accidents and injuries may oc-
cur.
● If the Emergency Assist does not operate
properly, sw
itch off the Lane Assist

Parking assistant (RCTA) Fig. 211
Schematic representation of the rear

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. 208 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. 211, an acoustic alarm is heard.
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. 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 can interrupt the automatic braking by
step
ping 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

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
