1. Turn the switch to position → Fig. 1 A .
WARNING
The rain and light sensor cannot always detect all precipitation sufficiently and activate the wipers. If visibility is restricted, this can
cause accidents and serious or fatal injuries.
● If necessary, switch on the wipers manually if the water on the windscreen restricts the field of vision.
Some settings can be stored in the personalised user accounts and therefore change when the user account changes.
Washer fluid level too low
The indicator lamp lights up yellow.
1. Fill up the washer fluid reservoir as soon as possible (→ Washer fluid).
Fault in wipers
The indicator lamp lights up yellow.
The wipers do not wipe.
1. Go to a suitably qualified workshop. Volkswagen recommends using an authorised Volkswagen repairer.
Fault in rain and light sensor

The wipers are not switched on automatically if it rains during rain and light sensor operation.

Changes in the response of the rain and light sensor
Possible causes for faults and misinterpretations relating to the sensitive surface of the rain and light sensor (→ Front view) include:
—
a film of water or smears caused by damaged wiper blades can increase the time the wipers are switched on,
can shorten the length of the intervals between wipes or cause the wipers to run quickly and continuously.
insects hitting the windscreen surface can cause the wipers to be activated.
—

—
in winter, salt deposits can cause the wipers to continue to wipe the windscreen when it is almost dry.
dry dust, wax, windscreen coatings (lotus effect), or detergent deposits (from an automatic car wash) can cause the rain and
light sensor to become less sensitive and react too slowly, or prevent it from reacting at all. Clean the sensitive surface of the rain
and light sensor at regular intervals and inspect the wiper blades for damage (→ Vehicle care, exterior).
—
a wipe cycle will be triggered if the rain and light sensor is switched on when the windscreen is impacted
by a stone. The rain and light sensor will then register the reduction in sensitivity of the surfaces and adjust accordingly. The size of
the crack can affect the way in which the rain and light sensor activates the wipers.
The wipers will try to wipe away any obstacles that are on the window. The wipers will stop moving if the obstacle blocks their
path.
1. Remove the obstacle and switch the wipers back on again.
