Hi Guys
Just a small problem you someone may have the answer to. When I select reverse the mirrors tilt down as they should, except the drivers mirror does not tilt enough. I thought it was sticking, so with reverse selected I manually tilt mirror down, so I know the movement is free. Question is it possible to program how far the mirrors tilt , if so how is it done ?
Also a question from the wife I cant answer.....if you exit the car with the engine running and someone else drives the car away..will the car stop when it realises the key is not present ?
Cheers
Ken
