Rain sensor*

Depending on how wet the windshield

is, the rain sensor controls the opera-

tion of the windshield wipers.

Infrared light is carried along the sur-

face of the windshield in an optical con-

ductor in such a manner that it is re-

flected completely when the windshield

is dry. The quantity of reflected light is

measured.

If there is moisture on the glass, the

amount of light reflected is reduced

since the infrared light at the surface of

the windshield can escape. The quan-

tity of reflected light is thus a means of

gauging the degree of wetness on the

windshield.

When the system is set to the "Intermit-

tent" wiper speed, the wipers react im-

mediately – if water is splashed onto the

windshield by vehicles traveling ahead

of you, for example. As a result, the rain

sensor contributes to driving safety and

comfort.
