eled since they were last set to zero)●a clock
●an hour meter (which shows the total time the
engine has been running)●a fuel meter●a self-diagnosis device
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
“km/h”.
