Saw one of these threads on an old forum i was on and it was quite good to see what other people knew, little tricks, that your car can do with out you knowing! Things like: 1. Air Con goes into recirculation mobe when you put it in reverse and also when you use the front screen wash!!!! (only found that out yesterday!!! ) 2. The indicator sound that comes from the instrument cluster gets louder the faster your going! I know its a bit geeky but add things if you know anymore!
