The speedometer indicates the speed of the vehicle.
The display mode can be changed from odometer to trip meter A to trip meter B and then back to odometer by pressing the selector while one of them is displayed. The selected mode will be displayed.

Odometer
The odometer records the total distance the vehicle has been driven.
Trip meter
The trip meter can record the total distance of two trips. One is recorded in trip meter A, and the other is recorded in trip meter B.
For instance, trip meter A can record the distance from the point of origin, and trip meter B can record the distance from where the fuel tank is filled.
When trip meter A is selected, pressing the selector again within one second will change to trip meter B mode.
When trip meter A is selected, TRIP A will be displayed. When trip meter B is selected, TRIP B will be displayed.
The trip meter records the total distance the vehicle is driven until the meter is again reset. Return it to “0.0” by depressing and holding the selector for one second or more. Use this meter to measure trip distances and to compute fuel consumption.
