traveled)
a tripmeter (which shows the distance traveled
since it was last set to zero)
Odometer and tripmeter modes
Pushing the “SELECT” button switches the display
between the odometer mode “ODO” and the trip-
meter mode “TRIP” in the following order:
ODO → TRIP → ODO
To reset the tripmeter, select it by pushing the “SE-

key to “ON”, and keeping them in this position for
at least two seconds switches the display between“mph” and “km/h”.
