Odometer and tripmeter modes
Pushing the “ SELECT” button switches the display
between the odometer mode “ ODO” and the trip-
meter modes “ TRIP A” and “ TRIP B ” in the follow-
ing order:
ODO → TRIP A → TRIP B → ODO
To reset a tripmeter, select it by pushing the “SE-
LECT ” button, and then push the “ RESET” button
for at least three seconds. The tripmeters can be
used to estimate the distance that can be traveled
with a full tank of fuel. This information will enable
you to plan future fuel stops.TIPPushing and holding in the “SELECT ” button, and
turning the key to “” (on) while the button is
pushed, switches the display between “mph” and
