In responce to tow/haul question, if you have the 5 speed transmission it turns off 5th gear. If it still repeatedly shifts back and fourth between 3rd and 4th then you shoud push the tow/haul button again and it will disengage 4th gear and O/D Off will illuminate on your dash. Either mode raises you shift points and down shifts your transmission sooner to help aid in slowing down.
