Wiper Switch
The wiper switch is also a momentary switch. It does not engage in fixed positions for its various functions.
The control concept incorporates a sequential mode. That means that the wiper speed settings are selected by tapping the stalk repeatedly the required number of times in the desired direction.
The wiper switch also incorporates an axial (push-button) switch (1). The Rain/Light sensor (RLS), system is switched on and off by this switch. The function is indicated by an LED (3).
When the ignition is switched "OFF", the wiper and the rain sensor are switched off at the same time.
The rain sensor is activated by means of the push-button switch on the wiper stalk. The LED then lights up.
When the rain sensor is switched on, the windshield wipers are controlled automatically according to how much precipitation (rain or snow) is on the windshield.
That includes switching them on and off and selecting the required setting from intermittent to continuous wipe. The rain sensor is switched off by touching the push-button switch again or automatically when the ignition is switched OFF.
The adjuster wheel sets the sensitivity of the rain sensor to a choice of 4 levels.
