Both of the trip odometers can be used simultaneously.
TRIP A could be used to track the distance to a
destination. TRIP B could be used to track maintenance
periods. The trip odometers can be reset by pressing
the RESET button on the DIC.
There is also a miles since last ignition feature that
displays the number of miles (kilometers) driven since
you last started the vehicle. Press and hold the
RESET button for three seconds, then release it.
The miles (kilometers) since the last ignition cycle will
be set into the trip odometer.
