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 . This sensor can detect vehi-
1
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.
Driver assistance systems
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.
