Hi.
Our MY09 VR dual-cab Auto Diesel is my first Auto car with an overdrive, so I wanted to ask members, how best to use it.
Our dealer suggested we drive with it OFF (so the instrument light for it glows OFF) around town, and only switch it on when above 80km/h (i.e. Highway, Expressway, divided road with 80km/h+ speed limit), however I'd like to hear more opinions on this as we're getting rather poor economy in our town cycle according to the avg. consumption gauge..
Discuss.
