The radar sensor's visibility may be impaired
by dirt, or by environmental influences such
as rain or mist. In this case, the Front Assist
does not work. The instrument panel displays
the following message: Front Assist: No

Driving
When the radar sensor begins to operate
properly again, the Front Assist will be availa-
ble again. The message will disappear from
the screen.
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.
guard rails or sheets used in road works).
The area in front of and around the radar
sensor and the front camera should not be
covered with adhesives, additional or similar
headlights, as this may negatively affect
Front Assist operation.
If the front of the vehicle is not properly re-
paired or structural modifications are made
to it, Front Assist operation may be affected.
SEAT recommends visiting a SEAT dealership
for this purpose.
CAUTION
If the Front Assist does not work as descri-
bed in this chapter (e.g. it repeatedly inter-
venes unnecessarily), switch it off. Have the
system checked by a specialised work-
shop. SEAT recommends visiting a SEAT
dealership.
Always adapt your speed and distance
●
away from the vehicle in front of you at all
times to suit visibility, weather, road and
traffic conditions.
If the operation of the Front Assist is im-
●
paired by dirt or because the radar sensor
has lost its settings, the system may issue
unnecessary warnings and intervene inop-
portunely in the braking.
The Front Assist does not react to animals
●
or vehicles crossing your path or ap-
proaching head-on down the same lane.
If you have the feeling that the radar sen-
●
sor or the front camera are damaged or
have lost their settings, disconnect the
Front Assist. This will avoid possible dan-
gerous situations caused by the inade-
quate operation of the system. If this oc-
curs have it adjusted.
The sensor and the front camera may be
●
maladjusted if they receive an impact. This
may compromise the system's efficacy or
disconnect it.
Repairs to the radar sensor and the front
●
camera require specialist knowledge and
special tools. SEAT recommends visiting a
SEAT dealership for this purpose.
A registration plate or plate holder on the
●
front that is larger than the space for the
registration plate, or a registration plate
that is curved or warped can cause the ra-
dar to malfunction.
Clean away the snow with a brush and
●
the ice preferably with a solvent-free de-
icer spray.
