Headlight washers
How do they work - or are they dummies?
I can't find anything in the manual, and when I spray the windshield with the lights on (automatic mode), they do not function.

Headlamp cleaning system
The headlamps are cleaned automatically if
the "Wipe with washer fluid" function is
operated five times (Y page 136) while the
lights are on and the engine is running. When
you switch off the ignition, the automatic
headlamp cleaning system is reset and
counting is resumed from 0.

I tested this out on my 2015 GL today since it was raining. I repeatedly pushed the windshield washer button and on the 5th time, the headlight washer also activated.

Mine don't work. I cannot get the washers to function. With the car in park, engine running, lights manually turned on... Pushing 5x, even 25x on the wash button does nothing.
Maybe the car needs to be drive, or it has to be dark, or it needs to be raining?!
MB should just put a button on the dash or turn stalk!

No dummy
So I know this thread is old but I was trying to figure out how they worked also. I had an Audi that worked anytime the headlights were on and sprayer was in for more than like 2 seconds. I had to replace the airmatic compressor today and poked the trap door open from behind. I have a nozzle and a hose supplying it. I’m sure I hit the windshield washers at least 5x but maybe lights need on manual and not auto? 2010 Gl450
