teach me -light question
turns on my L shaped "fog lights" .I'm not sure how functional they are but I like the the way they look while they are on.Since I leave the lights on auto all the time do I have to manually turn these on when I want them much like the c/s button?
I will say that even after re-reading the manual several times I'm amazed at how unclear this section is. (To me anyway).
On/off/auto would have been enough but we have on 1/on 2/off/auto/adaptive/fog geez!
But functionally at least at 530am the only thing it did was turn on/off the Lower lights that I always assumed were the DTR lights. When I press it I get orange fog lamp on dash.
In the US it is simply a nice extra safety convenience. In Europe it is mandatory to be used in foggy conditions. Your car (if European spec) would not even pass the TUV inspection if it didn't work. I say this due to my 14 years of driving experience in Germany while serving in the USAF.

Picture me manual in hand in the dark pushing buttons and running around looking. Pretty funny actually.

At night do the DTR lights not also come on? It looked as if they only came on with the press of that button. At least in auto mode anyway.
Just like the look of them being on basically all the time but couldn't figure it out. So I asked here.
The 1/2 on 1/2 off are you parking lights. Turn the switch to that mode and push your indicator down or up to light up the left or right side lights on the car. Very useful when parking on dark streets.
The rest are pretty self explanatory but here is the manual for them:

You want to be looking under the "Lights" section.
Maybe in auto mode pushing that turns the lights to full from 10%
Maybe I didn't appreciate the10% illumination.
I will look again but I do know that nothing illuminated on the rear .
I did get one rear fog to come on but they seem to alternate function with the front DTRLs.
Never got both working. But who cares. i did see the dimmer version of the DTRLs when auto actually kicked in briefly (was overcast/raining).
So it is still sort of a mystery. The rear fog button under some circumstances turns on the rear fogs but also controls the front DTRLs when in auto. For me only the left rear fog ever came on (dead bulb?). Front DTRLs did not consistently come on with the headlights after multiple pushes on the rear fog button.
First time I tried them after turning on the car DTRLs were dimmed but I hit the button above and they came on full bright. After that they seemed detached from subsequent pushes . Really on odd setup.
That is a cool little trick. It basically turns the lights on regardless of ambient light.
Why only one side?
Remember that contrary to the US (where people love to turn on the fogs in clear weather) European law requires the rear fog to be used when visibility is under 50 meters (@50 yards) and a ticket is issued if the fog light is used in better visibility. Since the fog is intended to be used when the other lights aren't visible, the single fog identifies the driver's side of the car.
