The amount of black smoke trapped is indicated
by the trapping indicator lamp, the alarm indi-
cator lamp and the buzzer, in that order.
(4) If a malfunction occurs in the DPF System,
the alarm indicator lamp comes on and the
buzzer rings for 5 seconds.
Caution
When the alarm indicator lamp comes on,
stop operation and request an inspection from
your Toyota dealer.

Carry out DPF maintenance when a day's op-
eration is over.
Toyota DPF-II System maintenance
method (Option)
Caution on maintenance
• Use a single phase AC200~240V external
power source, rated 15 A or more. Connect
securely to a power source earth.
• Have any repairs to the external power sup-
ply plug done by an electrical specialist.
• Always fit an electromagnetic switch (with
earth leakage breaker) to the external cur-
rent plug electrical source.
• Do not allow water into the DPF air cleaner
when washing the vehicle, etc.
• When there is a power cutoff due to power
failure etc., the system might sense a malfunc-
tion making the alarm indicator lamp come
on. In this case, request an inspection from
your Toyota dealer.
• Check that there are no objects that can eas-
ily catch fire around the DPF System before
carrying out maintenance.
Select a location for maintenance which is well
ventilated (with a draught), away from the
rain and not near any waste paper etc. that
can easily catch fire.
• Do not handle the power plug with wet
hands. A high voltage is used (single phase
AC200~240V), so there is a danger of electric
shock.
• Before starting DPF maintenance opera-
tion, make sure that a specified external
power is supplied to the machine.
So long as the external power is not supplied,
regeneration will fail to start, even if at-
tempted.
• During maintenance operation, combus-
tion smoke is emitted out of the tail pipe.

ply connection socket and turn it in the locking
direction.

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.
• Always use your fingertip to operate the
switch panel on the display.
• If the maintenance indicator lamp should
come on without the buzzer sounding, ask a
Toyota dealer for an inspection.
(4) When maintenance starts, the maintenance
indicator lamp and the trapping indicator lamps
(all six) come on.
Note: The microcomputer (ECU) automatically
carries out maintenance, so the operator does not
have to attend to the vehicle.
