Radar sensors
The radar sensors for Blind Spo tAssist are inte-
grated into the rea rbum per. Make sure tha tthe
bumpers are free from dirt, ice or slush. The
sensors must not be covered ,for exampl eby
cycl eracks or overhanging loads. Following a
severe impact or in the event of damage to the
bumpers, have the functio nofthe radar sensors
checked at aquali fied specialist workshop.
Blind Spo tAssist ma ynolonger work properly. Monitorin
