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) (3/130) transmits information to the driver information module (DIM) on the Control area network (CAN) indicating
which function is selected.
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 display are erased using the READ button.
For additional information about the trip computer and text messages, see Design and Function, driver information module (DIM).
