Control Buttons

Control Buttons





Two control buttons are located between the 2 large needle instruments. The left button (S/R for Set/Reset) is used to reset the trip odometer reading, to call up the test functions and to call up the reset menu for the service interval indicator.
The right button (clock symbol) is used to set the time and to switch the service interval indicator (remaining distance/service date or vice versa).
