the vehicle has been driven.
Trip meter
The trip meter can record the total distance
of two trips. One is recorded in trip 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.
NOTE
 y (Vehicles with type B audio) If the fuel economy data is reset using
the fuel economy monitor, or trip A

function which synchronizes the fuel
economy monitor and the trip meter is
on, the fuel economy data and trip A are
reset simultaneously.
 Refer to Fuel Economy Monitor on page 4-85 .
 y Only the trip meters record tenths of
kilometers (miles).
 y The trip record will be erased when:
 y The power supply is interrupted
(blown fuse or the battery is
disconnected).
 y The vehicle is driven over 9999.9 km
(mile).
