""ODO/TRIP" knob This meter displays the odometer and two trip meters. To change the mode indication, push the "ODO/TRIP" knob briefly. Each time you push the knob, the mode changes in order from the odometer to trip meter A to trip meter B, then back to the odometer, etc. The odometer records the total distance the vehicle has been driven. The twin trip meter records two different distances independently. For example, you can use one meter to calculate the fuel economy and the other to measure the distance on each trip. To set the A trip meter to zero, display the A meter reading, push the knob and hold it. The same applies for the B trip meter. The data of trip meters will be cancelled if the electrical power source is disconnected. SERVICE REMINDER INDICATORS AND WARNING BUZZERS
