Press the maintenance switch on the display the buzzer
rings to start maintenance.
CAUTION!
• Remove your finger once the buzzer rings and the mainte-
nance indicator lamp comes on. Pressing the switch for a long
time stops maintenance operation procedure.
• With the engine switch ON, the power will not come on even if
you press the maintenance switch.
• If the external power is supplied, with the engine switch ON,
the buzzer will sound.

display.
• If the maintenance indicator lamp should come on without
the buzzer sounding, ask a BT dealer for an inspection.

When maintenance starts, the maintenance indicator lamp
and the trapping indicator lamps (all six) come on.
Note:
The microcomputer (ECU) automatically carries out mainte-
nance, so the operator does not have to attend to the vehicle.
5.
The trapping indicator lamps go out in sequence from right
to left (yellow / green) as maintenance proceeds (every 10
minutes).
6.
Once maintenance is over, all the indicator lamps go out and
maintenance automatically stops.
Note:
The time to complete maintenance is about 45 minutes, depend-
ing on the amount of trapping.
