as title, according to the manual my Astra J Sri should have welcome lighting. unlocking with keyfob turns on lights, puddle lights, interior lights etc etc. apparently it facilitates locating the vehicle in the dark.
Ive looked all thru the Vehicle personalisation menu's for "Exterior ambient lighting" but it aint there.
I assumed it was a standard feature as its not mentioned anywhere in the brochure as a optional extra.
