Id only be guessing.
I know where all mine are cos Ive done a fair bit of bulb swapping.
On mine (if you couldnt see it from the front), there is no indication from the back as to where the sidelight bulb is.
You have to take off the cover behind the main beam bulb and then down low is the sidelight bulb and wiring.
The wiring routes in from the side.
auto lights,I dont know.
Mine does have an auto dip (on or off) option on the menu but its only for the drl lights on or off
One thing ..my manual does have a reasonable guide on where all the bulbs are and how to change them even if it says dealer only for some of them.
You can now dload the original owners manual for your car both here and in the UK (if you dont have one)..Check the renault site or links here on the forum.
Go to the autobulbsdirect site ( http://www.autobulbsdirect.co.uk/
and enter your car details there , you can see the sidelight and indicator bulbs are separate.
Your sidelight bulb appears to be the 501 w5w wedge type (same as mine)
Final note,Halfords I believe do a bulb changing service for a small fee ,when you buy bulbs..you could watch n know for the next time.
