It will gives you lots of useful informations about services and repairs.
The reset procedure is also in the owners manual.

1. Step into car, shut the door and turn on the ignition. Do not crank/start engine. On this step, the service due message will post. Allow five seconds to pass until normal/regular information display is shown.

2. I then pushed the up arrow button on steering wheel to display service interval. It read 'Service B is due now'.

3. Push reset button (also serves as dasboard dimmer dial) left of temp gauge for several seconds. Service display will then show press for 3 seconds to reset timer. After three seconds with finger on reset button, timer will reset. Mine read 'Service A 13,000 miles'.
