WINDSHIELD LIGHT AND RAIN SENSOR

Light and rain
sensor
Details and Technology
Combined light and rain sensor fitted in the base of the interior mirror. Depending on the light switch
position, the low beam headlamps are switched on when it gets dark, when the vehicle enters a tunnel,
or when rain or snow are falling. The light sensor continuously compares the ambient light level outside
the vehicle with a set value and, when appropriate, switches the headlamps on and off. Depending on the
position of the windshield wiper combination stalk, the windshield wipers are also automatically activated
when conditions require. The sensor aims an infrared light beam at the windshield at a defined angle.
The intensity with which the light is reflected back depends on how wet the windshield is. Based on
the amount of reflected light, the system adjusts the wiper interval to anything from a single wipe to
continuous wiping. The sensing zone is heated to help prevent ice and condensation forming.
Benefits and Arguments
• Automatically controlled optimal wiping interval
• Low beam headlamps switched on and off automatically
Stress-free driving is ensured at all times, even in poor weather, since the driver does not have to adjust the
wiping interval manually. If only isolated drops are falling, wiping is not triggered as soon. The ideal wiping
interval is ensured under all weather conditions. The headlamps are switched on and off automatically in
response to changes in the ambient light level outside the vehicle.
