moving:
Stopping the engine while the vehicle is
moving for any reason other than in an
emergency is dangerous. Stopping the
engine while the vehicle is moving will
result in reduced braking ability due to the
loss of power braking, which could cause
an accident and serious injury.
1. Stop the vehicle completely.

When trip meter A is selected, pressing the
selector again within one second will
change to trip meter B mode.

When trip meter A is selected, TRIP A
will be displayed. When trip meter B is
selected, TRIP B will be displayed.

The trip meter records the total distance
the vehicle is driven until the 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
(Vehicles with type B audio)
If TRIP A is reset using the trip meter
when the function which synchronizes
(resets) the fuel economy monitor and
the trip meter (TRIP A) is on, the fuel
economy data resets in conjunction with
TRIP A.
Refer to Fuel Economy Monitor on page
4-69.
Only the trip meters record tenths of
kilometers (miles).
The trip record will be erased when:
The power supply is interrupted
(blown fuse or the battery is
disconnected).
