The trip meter records the total distance
the vehicle is driven until the meter is
again reset. Return it to 0.0 by holding
the selector depressed for more than 1
second. Use this meter to measure trip
distances and to compute fuel
consumption.

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).
The vehicle is driven over 999.9
km (mile).

The tachometer shows engine speed in
thousands of revolutions per minute
