Diesel particulate filter
warning light
(diesel engine models)
! When diesel particulate filter warn-
ing light illuminates
The diesel particulate filter warning light
illuminates when the filter is not able to
automatically burn the soot and the
accumulated particulate matter exceeds
the specified limit.
When the diesel particulate filter warning
light illuminates, drive the vehicle under
the following conditions after the engine
has been warmed up completely.
. Engine speed: 1,800 to 2,500 rpm
. Vehicle speed: 60 km/h (37 mph) or
faster is preferred
. Driving time for burn treatment: 15
minutes or more
NOTE
. Do not accelerate rapidly. Accelerate
the vehicle according to the upshift
timing shown in the shift-up indicator
light. During regeneration of the diesel
Instruments and controls/Warning and indicator lights
particulate filter, the shift-up indicator
will prompt the driver to accelerate to
the engine speed necessary for regen-
eration. For details about the shift-up
indicator light, refer to "Shift-up indi-
cator light (MT models)" F3-30.
. If it is difficult to maintain all these
conditions, maintaining at least the
specified engine speed will have some
effect for burning soot.
Driving under these conditions will in-
crease the inside temperature of the filter
and burn the accumulated soot to elim-
inate it. The warning light turns off when
the soot is eliminated.
WARNING
Even if the diesel particulate filter
warning light illuminates, continuing
to drive does not damage the engine
and diesel particulate filter immedi-
ately. Safely drive the vehicle ac-
cording to all road laws and the
traffic conditions. Otherwise, it may
cause an accident or traffic viola-
tion.
NOTE
While the soot is burning in the diesel
particulate filter, the driveability, engine
revolutions, engine sound and smell of
emission gas may change.
! When diesel particulate filter warn-
ing light flashes
When the diesel particulate filter warning
light flashes, we recommend that you
consult the nearest SUBARU dealer for
an immediate inspection.
CAUTION
If you continue to drive the vehicle
while the diesel particulate filter
warning light is illuminated, the
warning light will begin to flash. In
this case, we recommend that you
consult the nearest SUBARU dealer
for an immediate inspection. Other-
wise, the engine and diesel particu-
late filter may be damaged.
&
Over-rev warning light
(yellow) (diesel engine
models)
If engine over-revving is likely to occur, a
buzzer will sound and the over-rev warn-
ing light on the combination meter will
flash in yellow. For more details, refer to
"Over-revving warning (diesel engine
models)" F7-15.
