.
The r
a
d
ar 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 sensor ›››
.
When the r
a
d
ar 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 the front of the vehicle is not properly re-
paired or structural modifications are made
to it, for example, if the suspension is low-
ered, ACC operation may be affected. In this
scenario, SEAT recommends visiting a SEAT
dealership.
CAUTION
If you have the sensation that the radar sen-
sor is d
amaged 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.
●
A registration plate or plate holder on the
front that is larger than the space for the reg-
istration plate, or a registration plate that is
curved or warped can cause the radar to mal-
function.
●
Cle
an away the snow with a brush and the
ice preferably with a solvent-free de-icer
spray.
