Radar sensor

Fig. 199 

On the front bumper: radar sensor.

A radar sensor is installed on the front bump-
er to determine the traffic situation

››› 

Fig. 199 

1

. This sensor can detect vehi-

cles in front up to a distance of approximately
120 m.

The radar sensor's visibility may be impaired
by dirt, mud or snow, or by environmental in-
fluences such as rain or mist. In this case the
adaptive cruise control (ACC) does not work.
The instrument panel displays the following
message: 

ACC: No sensor vision!

 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. This may occur, for ex-
ample, in a closed car park or due to the
presence of metallic objects (e.g. rails on the
road or sheets used in road works).

The area in front of and around the radar sen-
sor should not be covered with adhesives,
additional or similar headlights, as this may
negatively affect ACC operation.

If structural modifications are made to the ve-
hicle, for example, if the suspension is low-
ered or the front spoiler is modified, ACC op-
eration may be affected. So structural modifi-
cations should only be made by specialised
workshops. SEAT recommends visiting a SEAT
dealership for this purpose.

If work is done incorrectly on the front of the
vehicle, the radar sensor could be damaged
or lose its settings, and ACC operation may
be affected. So repair work should only be
made by specialised workshops. SEAT recom-
mends visiting a SEAT dealership for this pur-
pose.

CAUTION

If you have the sensation that the radar sen-
sor is damaged or has lost its settings, dis-
connect the ACC. This will avoid possible
damage. If this occurs have it adjusted.

●

The sensor may become damaged or lose

its settings when knocked, for example, dur-

ing a parking manoeuvre. This may compro-
mise the system's efficacy or disconnect it.

●

Repairs to the radar sensor require special-

ist knowledge and special tools. SEAT recom-
mends visiting a SEAT dealership for this pur-
pose.

●

Clean away the snow with a brush and the

ice preferably with a solvent-free de-icer
spray.

Conditions for the adaptive cruise control to
be activated

●

The selector lever must be at the 

D or S po-

sition or in the tiptronic selection track. In
manual gearbox any forward gear must be
engaged, except the 1st gear.

●

In vehicles with manual gearbox, if there is

no programmed speed, drive at least at
30 km/h (18 mph).

Speed control
When the ACC is connected, speed can be
programmed and adjusted. The programmed
speed must be different from the speed at
which the vehicle travels if the distance is be-
ing adjusted at the time.

What functions can be operated?
If you activate the ACC the current speed can
be programmed as the “control speed”.

During driving, control can be operated at
any time and the speed also modified.

The following settings can also be adjusted:

●

page 219

.

The following driving programmes items can
be selected:

●

Normal

●

Sport

●

Eco

In vehicles without the driving profile selec-
tion function, acceleration behaviour can be
influenced by selecting a driving programme
on the Easy Connect system using the 



button and the 

SETUP

 and 

Driver assistance

function buttons

.

The following conditions may lead the ACC
not to react:

●

If the accelerator is pressed.

●

If there is no gear engaged.

●

If the ESC is controlling.

●

If the driver is not wearing his/her seat

belt.

●

If several brake lights of the vehicle or elec-

trically connected trailer are damaged.

●

If the vehicle is reversing.

●

Driving faster than 210 km/h (150 mph).

WARNING

There is a danger of rear collision when the
minimum distance 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 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 obligatory minimum distances be-
tween vehicles.

Note

●

The programmed speed is erased once the

ignition or the ACC are switched off.

●

When the traction control system (ASR) is

deactivated during acceleration or else the
ESC is activated in Sport* Mode
(

››› 

page 110

), the ACC switches off automati-

cally.

●

In vehicles with the Start-Stop system, the

engine switches off automatically during the
ACC stopping phase and restarts automatical-
ly to begin driving.

Vehicles with an automatic gearbox

If the vehicle is equipped with automatic
gearbox, the ACC can brake the vehicle until

Operation

Function to avoid overtaking on the
wrong side

Fig. 204 

On the instrument panel display:

ACC active, vehicle detected in an outer lane

The adaptive cruise control (ACC) has a func-
tion that helps 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. 204

.

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 interrupt this
intervention at any time.

Deactivating the Adaptive Cruise Con-
trol ACC temporarily in certain situa-
tions

In the following situations the Adaptive
Cruise Control (ACC) should be deactivated
due to the system's limitations 

››› 

:

●

When changing lanes, on tight bends and

roundabouts, 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

could be affected.

●

On roads with several lanes, when other ve-

hicles are driving more slowly in the overtak-
ing lane. In this case, slower vehicles will be
overtaken on the right.

●

In case of heavy rain, snow or spray, as the

vehicle 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 described, 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 situations, you may commit a le-
gal offence.

(C) Vehicle changing lanes. (D) One

vehicle turning and another stationary.

The adaptive cruise control (ACC) has certain
physical 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.

Overtaking
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 200

.

Driving through a bend
On entering or exiting bends, the radar sen-
sor may no longer determine the vehicle in
front or react to a vehicle in the adjacent lane

››› 

Fig. 205

 

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 200

.

Driving in tunnels
When driving through tunnels the radar sen-
sor may be limited. Switch off the ACC in tun-
nels.

Operation

Narrow or misaligned vehicles
The radar sensor can only detect narrow or
misaligned vehicles when they are within
range 

››› 

Fig. 205

 

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
Vehicles 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. 206

 

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. 206

 

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
operates
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

time it means that there is a fault. Contact a
specialised workshop. SEAT recommends vis-
iting a SEAT dealership.

WARNING

If the message ACC ready to start ap-
pears on the instrument panel display and
the vehicle in front starts up, the vehicle will
start up automatically. In this case the radar
sensor may not detect obstacles on the road.
This could cause an accident and serious in-
juries.

●

Before driving off, check that the road is

clear. If necessary, apply the brake.

Driver assistance systems

Front Assist system including
City emergency braking and
pedestrian monitoring*

Introduction



 

››› 

table on page 2

The Front Assist system including City emer-
gency braking and pedestrian monitoring can
help avoid collisions.

The Front Assist system may warn the driver,
within the constraints of the system, of im-
pending collisions, prepare the vehicle for
emergency braking in case of danger, provide
support during braking and apply automatic
braking.

The City emergency braking and pedestrian
monitoring functions are an integral part of
the Front Assist system.

The Front Assist is not a replacement for
driver awareness.

Distance warning
If the system detects that safety is endan-
gered by the proximity of the vehicle in front,
it may warn the driver by means of a message
on the instrument panel when driving at a
speed of between approximately 60 km/h
(37 mph) and 250 km/h (156 mph)

››› 

Fig. 207

.

The warning moment varies depending on
the traffic situation and driver behaviour.

Advance warning
If the system detects a possible collision with
the vehicle in front, it may warn the driver by
means of an audible warning and an indica-
tion on the instrument panel when driving at
a speed of between approximately 30 km/h
(18 mph) and 250 km/h (156 mph)

››› 

Fig. 207

.

The warning moment varies depending on
the traffic situation and driver behaviour. At
the same time, the vehicle will prepare for a
possible emergency braking 

››› 

.

Critical warning
If the driver fails to react to the advance
warning, the system may actively intervene in
the brakes when driving at a speed of be-
tween approximately 30 km/h (18 mph) and
250 km/h (156 mph), generating a brief jolt
to warn of the imminent collision.

Automatic braking
If the driver also fails to react to the advance
warning, the system may brake the vehicle
automatically, by progressively increasing
braking effect driving at a speed of between
approximately 4 km/h (2.5 mph) and
250 km/h (156 mph). By reducing speed in
case of a possible collision, the system may

contribute to reducing the consequences of
an accident.

Front assist
If the Front Assist notices that the driver is
not braking sufficiently in case of a collision
hazard, the system can increase braking ef-
fect and thus avert the collision when driving
at a speed of between approximately 4 km/h
(2.5 mph) and 250 km/h (156 mph). Front
assist only acts while the brake pedal is
pressed down hard.

WARNING

The intelligent technology in the Front Assist
cannot change the laws of physics. The driver
is always responsible for braking in time. If
the Front Assist issues a warning, then, de-
pending on the traffic circumstances, you
must brake immediately or dodge the obsta-
cle.

●

Adapt your speed and safe distance to the

vehicle in front of you at all times to suit visi-
bility, weather, road and traffic conditions.

●

The Front Assist alone cannot avoid acci-

dents and serious injuries.

●

In complex driving situations, the Front As-

sist may issue unnecessary warnings and in-
tervene unnecessarily in braking, such as in
traffic islands.

●

If the operation of the Front Assist is im-

paired, for example, by dirt or because the ra-
dar sensor has lost its settings, the system

may issue unnecessary warnings and
intervene inopportunely in the braking.

●

During driving, the Front Assist does not re-

act to people or animals or vehicles crossing
your path or which approach you head-on in
the same lane.

●

The driver must always be ready to take

over the control of the vehicle.

Note

●

When the Front Assist causes a braking,

the brake pedal is “harder”.

●

Automatic interventions by the Front Assist

on the brakes may be interrupted by pressing
the clutch, accelerator or moving the wheel.

●

If the Front Assist does not work as descri-

bed in this chapter (e.g. in intervenes several
times unnecessarily), switch it off. Have the
system checked by a specialised workshop.
SEAT recommends visiting a SEAT dealership.

Radar sensor

Fig. 208 

On the front bumper: radar sensor.

A radar sensor is installed on the front bump-
er to determine the traffic situation

››› 

Fig. 208

. This sensor can detect vehi-

cles in front up to a distance of approximately
120 m.

The radar sensor's visibility may be impaired
by dirt, mud or snow, or by environmental in-
fluences such as rain or mist. In this case the
Front Assist monitoring system does not
work. The instrument panel displays the fol-
lowing message: 

Front Assist: No

sensor vision!

 If necessary clean the ra-

dar sensor 

››› 

.

When the radar sensor begins to operate
properly again, the Front Assist will automati-
cally be available again. The message will
disappear from the instrument panel display.

Driver assistance systems

Front Assist operation may be affected by a
strong radar reverse reflection. This may oc-
cur, for example, in a closed car park or due
to the presence of metallic objects (e.g. rails
on the road or sheets used in road works).

The area in front of and around the radar sen-
sor should not be covered with adhesives,
additional or similar headlights, as this may
negatively affect Front Assist operation.

If structural modifications are made to the ve-
hicle, for example, if the suspension is low-
ered or the front spoiler is modified, Front As-
sist operation may be affected. So structural
modifications should only be made by speci-
alised workshops. SEAT recommends visiting
a SEAT dealership for this purpose.

If work is done incorrectly on the front of the
vehicle, the radar sensor could be damaged
or lose its settings, and Front Assist opera-
tion may be affected. So repair work should
only be made by specialised workshops.
SEAT recommends visiting a SEAT dealership
for this purpose.

CAUTION

If you have the sensation that the radar sen-
sor is damaged or has lost its settings, dis-
connect the Front Assist. This will avoid pos-
sible damage. If this occurs have it adjusted.

●

The sensor may become damaged or lose

its settings when knocked, for example, dur-

ing a parking manoeuvre. This may compro-
mise the system's efficacy or disconnect it.

●

Repairs to the radar sensor require special-

ist knowledge and special tools. SEAT recom-
mends visiting a SEAT dealership for this pur-
pose.

●

Clean away the snow with a brush and the

ice preferably with a solvent-free de-icer
spray.

City Emergency braking function

Fig. 210 

On the instrument panel display: ad-

vance warning message

The City emergency braking function is part
of Front Assist and is active whenever the
system is switched on.

Depending on the equipment, the City emer-
gency braking function may be switched on
and off in the Easy Connect system using
the 



 button and the 

SETUP

 and

Driver assistance

.

The City Emergency braking function picks
up, at speeds between approximately 4 km/h
(2.5 mph) and 30 km/h (19 mph), the traffic
situation in front of the vehicle.

If the system detects a possible collision with
a vehicle in front of it, the vehicle prepares
for a possible emergency braking 

››› 

.

If the driver fails to react to a possible colli-
sion, the system may brake the vehicle auto-
matically, by progressively increasing braking
effect driving to reduce speed in the event of
a collision. The system can thus help to re-
duce the consequences of an accident.

Status display
Automatic deceleration by means of the City
Emergency braking function is displayed on
the instrument panel by means of the ad-
vance warning

WARNING

The smart technology included in the City
Emergency braking function cannot defy the
laws of physics. The driver is always respon-
sible for braking in time.

●

Adapt your speed and safe distance to the

vehicle in front of you at all times to suit visi-
bility, weather, road and traffic conditions.

●

The City Emergency braking function alone

cannot prevent accidents or serious injury.

●

In complex driving situations, the City

Emergency braking function may issue unnec-
essary warnings and intervene inopportunely
in braking, such as in work areas or if there
are metal rails.

●

If the operation of the City Emergency brak-

ing function is impaired, for example, by dirt
or because the radar sensor has lost its set-
tings, the system may issue unnecessary
warnings and intervene inopportunely in the
braking.

●

During driving, the City Emergency braking

function does not react to people or animals
or vehicles crossing your path or which ap-
proach you head-on in the same lane.

Note

●

When the City Emergency braking function

causes a braking, the brake pedal is “hard-
er”.

●

Automatic interventions on the brakes by

the City Emergency braking function may be
interrupted by pressing the clutch, accelera-
tor or moving the wheel.

●

The City Emergency braking function can

brake the vehicle until it stops completely.
However, the brake system does not halt the
vehicle permanently. Use the foot brake!

WARNING

The technology in the pedestrian monitoring
system 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 with 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 monitoring 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 example, 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

over the control of the vehicle.

››› 

table on page 2

WARNING

The intelligent technology in the Lane Assist
system 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

road 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-

roundings.

●

When the area of vision of the camera be-

comes dirty, covered or is damaged, the Lane
Assist system function can be affected.

CAUTION

In order to avoid influencing the operation of
the system, the following points must be tak-
en into account:

●

Regularly clean the area of vision of the

camera and keep it in a clean state, without
snow or ice.

●

Do not cover the area of vision of the cam-

era.

●

Check that the area of vision of the wind-

screen camera is not damaged.

Note

●

The Lane Assist system has been exclusive-

ly developed for driving on paved roads only.

●

If the Lane Assist system does not work as

described in this chapter, do not use it and
contact a specialised workshop.

●

If there is a fault in the system, have it

checked by a specialised workshop.
