Radar sensors
On the front bumper: radar sensors.

Driver assistance systems
A radar sensor is fitted on the front bumper
›››
Fig. 164.
The radar sensor's visibility may be impaired
by dirt, or by environmental influences such
as rain or mist. In this case the adaptive cruise
control (ACC) does not work. The instrument
panel displays the following message: ACC:
Clean the radar sensor
No sensor vision!
›››
.
When the radar sensor begins to operate
properly, the ACC will become available. The
message on the screen will switch off and the
ACC may be reactivated.
ACC operation may be affected by a strong
radar reverse reflection. This may occur, 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 should not be covered with adhesives,
additional or similar headlights, as this may
negatively affect ACC operation.
If the front of the vehicle is not properly re-
paired or structural modifications are made
to it, ACC operation may be affected. In this
scenario, SEAT recommends visiting a SEAT
dealership.
CAUTION
If you have the sensation that the radar
sensor is damaged or has lost its settings,
disconnect the ACC. This way you can
avoid possible damage. If this occurs have
it adjusted.
The sensor may not be adjusted correct-
●
ly if it receives an impact. This may com-
promise the system's efficacy or discon-
nect it.
Repairs to the radar sensor require spe-
●
cialist 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.
