The warning light will go out and the buzzer
will stop when the door is closed or the
parking brake is applied.
Regeneration Required Warning Light
REGEN. REQUIRED
This light (amber) comes on when Running
regeneration or Switch regeneration is
required. When this light comes on, perform
DPF regeneration soon. If the engine
continues to run without performing DPF
regeneration, this light will change color
from amber to red. If this light turns red,
perform DPF regeneration immediately.
If you do not perform DPF regeneration, the
check engine malfunction indicator light and
reduced engine power indicator light will
come on, imposing performance restriction
on the vehicle. If this happens, the vehicle
must be serviced at your dealer. See Diesel
Particulate Filter 0 147.
If your vehicle is equipped with a power
take-off (PTO), monitor the DIC for DPF
related indicators. PTO and other slow speed
applications may require more attention.

Required Warning Light
SEL REGEN. REQUIRED
Performing the Selectable regeneration:
After the Checking PM Level Light is shown,
this light comes on in amber when
Selectable regeneration is possible. When
the DPF switch is pressed with this light ON,
"Selectable" regeneration starts.
When the selectable regeneration or switch
regeneration is interrupted: This light
(amber) comes on when the "Selectable"
regeneration or "Switch" regeneration is
interrupted. When this light comes on,
perform DPF regeneration promptly by
following the procedure for the "Switch"
regeneration. If you continue to operate the
vehicle without performing DPF
regeneration, the color of this light changes
to red from amber. When this light comes
on in red, perform DPF regeneration
immediately by following the procedure for
the switch regeneration. If you do not
perform DPF regeneration, the check engine
malfunction indicator light and reduced
engine power indicator light will come on,
imposing performance restriction on the
vehicle. If this situation happens, the vehicle
must be serviced. See Diesel Particulate Filter

take-off (PTO), monitor the DIC for DPF
related indicators. PTO and other slow speed
applications may require more attention.
Regeneration in Progress Light
REGEN. IN PROGRESS
When this light is ON, DPF regeneration is in
progress. When the vehicle is stationary, the
exhaust sound changes as the engine speed
increases. Also, operating sounds of the
exhaust throttle may be heard. Keep people
and flammable objects away from the
exhaust pipe, because the exhaust
temperature becomes high during
regeneration. When regeneration is
completed, the light goes out automatically.
See Diesel Particulate Filter 0 147.
During extended engine idling, this light
may appear on the DIC and the DPF may be
automatically regenerated.
