The wipers do not wipe. 
The indicator lamp lights up yellow. 
Switch the ignition off and on. 
If the problem persists, go to a qualified workshop. 
Changes in the activation behaviour of the rain/light sensor 
Possible causes for faults and misinterpretations relating to the sensitive surface of the rain/light 
sensor 
Damaged wiper blades: 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: insects hitting the windscreen can cause the wipers to be activated. 
Salt deposits: in winter, salt deposits can cause the wipers to continue to wipe the windscreen when 
it is almost dry. 
Dirt: dry dust, wax, windscreen coatings (lotus effect), or detergent deposits (from an automatic car 
wash) can cause the rain/light sensor to become less sensitive and react too slowly, or prevent it 
from reacting at all. Clean the sensitive surface of the rain/light sensor Caring for and cleaning the 
vehicle exteriorat regular intervals and inspect the wiper blades for damage. 
Crack in the windscreen: a wipe cycle will be triggered if the rain/light sensor is on when the 
windscreen is impacted by a stone. The rain/light sensor will then register the impairment of the 
sensitive surfaces and adjust accordingly. Depending on the size of the stone impact, the activation 
behaviour of the rain/light sensor may be changed. 
We recommend that you use an alcohol-based glass cleaner to remove wax and polish. 
 
The wipers will try to wipe away any obstacles that are on the window. The wiper will stop moving if 
the obstacle continues to block its path. Remove the obstacle and switch the wiper back on again.
