Hi Johndouglas, Thanks for the quick reply. I know what you said about the owner's manual. its generally for all ranges of same model. but inside the car setting menu, i have seen parking sensor is activated and i can deactivate too. so doesn't it mean that this specific car has this option. and what about the wing mirror? is it general for all cars? I can not see any movement of wings mirrors with rear gear action. BTW, i forgot to add, I can not get my climate control work when car is in ignition mode. it was working before but somehow i did something and now it doesn't work until i start the engine? you have been great helped. I'll look at the link that you have given. thank you very much..any more suggestion from anybody would be appreciated.
