Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Trip computer and displaying/erasing text messages
The left-hand control stalk is used to control the trip computer and to display and erase text messages in the driver information module (DIM) (5/1).
The steering wheel module (SWM) (3/254) transmits data to the central electronic module (CEM) using LIN communication to indicate the selected function. The central electronic module (CEM) (4/56) forwards this data to the driver information module (DIM) via the CAN network.
The trip computer menu is controlled using the ring on the left-hand control stalk. Turn the ring forwards or backwards to scroll through the menu one step at a time. Some menu selections, such as average speed and fuel consumption, can be reset using the RESET button.
Error messages displayed in the driver information module (DIM) display are erased using the READ button.
For additional information about the trip computer and text messages, see DRIVER INFORMATION MODULE, TIRE PRESSURE MONITORING - DESIGN AND FUNCTION .
