restart the engine. The engine must be star-
ted manually.
Start-Stop system: Fault! Function not available
There is a fault in the Start-Stop system. Take
the vehicle to a workshop to have the fault
repaired.
Cruise control system (CCS)* How it works The cruise control system (CCS) is able to
maintain the set speed from 20 km/h (15
mph). The CSS only reduces vehicle speed by ceas-
ing to accelerate, not by actively braking the
vehicle
››› .
WARNING
Use of the cruise control could cause acci-
dents and severe injuries if it is not possible
to drive at a constant speed maintaining the
safety distance.
● Do not use the cruise control in heavy traf-
fic, if the distance from the vehicle in front is
insufficient, on steep roads, with several
bends or in slippery circumstances (snow,
ice, rain or loose gravel), or on flooded roads.
● Never use the CCS when driving off-road or
on unpaved roads.
● 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.
● To avoid unexpected operation of the cruise
control system, turn it off every time you fin-
ish using it.
● It is dangerous to use a set speed which is
too high for the prevailing road, traffic or
weather conditions.
● When travelling down hills, the CCS cannot
maintain a constant speed. The vehicle tends
to accelerate under its own weight. Select a
lower gear or use the foot brake to slow the
vehicle. Warning and control lamp

Operation
Safety
The essentials

Operation
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 160 km/h (100 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 81),
the ACC switches off automatically.
● 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
it stops completely if a vehicle in front of it
stops.
The ACC will still be available for a few sec-
onds. The vehicle will restart by itself if the
vehicle in front moves (traffic jam assistant).
Disconnection criteria
The ACC will switch off if the driver applies
the brake pedal or the driver's door is
opened.
If the vehicle in front remains stationary for
more than 3 seconds, the ACC will also
switch off for safety reasons.
In this case the
driver should take control and apply the
brake. In the latter case, when the ACC is switched
off with the vehicle stationary, the vehicle
has to be braked by the pedal, since al-
though the car is idling it can move, as there
is a gear engaged.
Restarting the vehicle with the ACC manually
The ACC can be activated again by moving
the lever to position
2
››› Fig. 154 . WARNING
Your vehicle can start up even if there is an
obstacle between your vehicle and the vehi-
cle detected in front. Risk of accident! CAUTION
● If your vehicle with ACC does not start up
as expected, you can drive off by briefly step-
ping on the accelerator.
● The Start-Stop system usually acts if you
are driving with ACC. 156

Driver assistance systems
Radar sensor Fig. 159
On the front bumper: radar sensor. A radar sensor is installed on the front bump-
er to determine the traffic situation
››› Fig. 159 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
Front Assist monitoring system does not
work. The instrument panel displays the fol-
lowing message: Front Assist: No sensor vi- sion! If necessary clean the radar 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.
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. Operating the Front Assist monitoring

If the Front Assist is not switched off in the
situations described, serious accidents and
injuries may occur.
● Switch off the Front Assist in critical situa-
tions. System limitations
The Front Assist Monitoring System has cer-
tain physical limitations inherent in the sys-
tem. Thus, in certain circumstances some of
the system's reactions may be inopportune
or be delayed from the driver's standpoint.
So pay attention in order to intervene if nec-
essary.
The following conditions may cause the Front
Assist Monitoring System not to react or do
so too late:
● On taking tight bends.
● Pressing the accelerator all the way down.
● If the Front Assist is switched off or dam-
aged.
● If the ASR has been manually disconnec-
ted.
● If the ESC is controlling.
● If several brake lights of the vehicle or elec-
trically connected trailer are damaged.
● If the radar sensor is dirty or covered.

Parking aid
General information Various systems are available to help you
when parking or manoeuvring in tight spaces, depending on the equipment fitted
on your vehicle.
The
rear parking aid
is an audible assistant

Durin

g parking, the
parking system plus as-
sists you visually and audibly about obsta-
cles detected in front and behind
the vehicle
››› page 174. WARNING
● Always 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.
● Take into account that the system is not al-
ways in conditions to recognise or represent
certain surfaces, such as dress fabric: Risk of
causing an accident!
● The sensors and cameras have blind spots,
making the detection of people and objects
impossible. Pay special attention to children
and animals: Risk of causing an accident!
● Always keep visual control of the vehicle
surroundings: use the rear vision mirrors for
additional help. CAUTION
● Under certain circumstances, the system
does not detect or display certain objects:
– Objects such as snow chains, trailer draw
bars, bars or fences.
– Objects that are located above the sen-
sors, such as protrusions in a wall.
– Objects with certain surfaces or struc-
tures, such as wire mesh fences or pow-
der snow.
● Please note that low obstacles detected by
the system may no longer be registered by
the sensors as the car moves closer, so the
system will not give any further warning. In
certain circumstances, objects such as high kerbs that could damage the bottom of the
vehicle are not detected either.
● If the first warning from the Park Pilot is ig-
nored, the vehicle could suffer considerable
damage.
● The knocks or damage on the radiator
grille, bumper, wheel arch and vehicle under-
body can adjust the orientation of the sen-
sors. This can affect the parking aid function.
Have the function checked by a specialised
workshop. Note
● In certain situations, the system can give a
warning even though there is no obstacle in
the detected area, e.g: » 173

– Press the  button, or
– switch the ignition off. Segments of the visual indication
The distance of separation from the obstacle
can be estimated using the segments around
the vehicle.
The graphic display of the segments varies
according to the vehicle's equipment:
The yellow trail indi-
cates the vehicle's expected journey
based on the steering wheel angle. A
white
segment is displayed when the
obstacle is not within the vehicle's tra-
jectory or the direction of travel would
avoid it entering the vehicle's trajectory.
If the obstacle is within the vehicle’s tra-
jectory, a yellow segment is displayed
(at

a distance of more than 30 cm) or a
red
segment (at a distance of less than
30 cm) at the same time as the corre-
sponding audible warning sounds.
The
yellow trail indicates the vehicle's ex-
pected journey based on the steering
