Driving and Operating
"Switch" regeneration will be interrupted in
the following circumstances.
.
Accelerator pedal is pressed
.
Selector lever is moved to a driving range
(R, OD, 3, 2, or 1) position
.
Vehicle speed is above 0 km/h (0 MPH)
.
Engine speed increases
Operation noise caused by interruption is
louder when depressing the accelerator
pedal than other operations. This is not a
failure.
DPF Regeneration during Prolonged
Idling
Automatic DPF regeneration may be
initiated during prolonged idling. If this
occurs, the high exhaust system
temperature indicator light will come on.
This is normal and does not indicate a
failure.
If Automatic regeneration that is started as
a result of prolonged idling is interrupted
(by either driving the vehicle or activating a
PTO), the high exhaust system temperature
indicator light will go out and the DPF
warning light will come on. Perform "Switch"
regeneration soon in order to complete the
DPF regeneration.
Prolonged idling may require more frequent
DPF regeneration.

Diesel Exhaust Fluid
Diesel exhaust fluid (DEF) is used exclusively
for the selective catalytic reduction (SCR)
system. Be sure to use only API certified
DEF. When the SCR system detects DEF level
is nearly empty or incorrect fluids (such as
water or low concentrated DEF.) are added,
the SCR system will turn on warning and
indicator lights and reduce engine power in
progressive stages to encourage you to have
the condition corrected. Continuing to drive
for too long after these lights come on will
eventually result in a severe vehicle speed
limitation. See
The DEF freezes below
−
11 °C (12 °F). The SCR
system is equipped with a heating function
which utilizes the engine coolant, so the
engine can be started even when DEF is
frozen.
Handling of DEF
Use only API certified DEF (or ISO: AUS 32).
DEF is a colorless, transparent solution.
It may smell depending on the conditions,
but this is not abnormal.
DEF is available from your local authorized
dealer. In addition, the U.S. Department of
Energy has created an on-line DEF locator
that can be accessed at
https://www.afdc.energy.gov/afdc/locator/
def/. The American Petroleum Institute (API)
also maintains a list of API-certified
distributors of DEF on its web page at
https://www.apidef.org/searchresults.asp.

Warning
Avoid getting Diesel Exhaust Fluid (DEF)
on your skin or in your eyes as it could
cause irritation. For more safety,
handling, and storage information, see
the Diesel Exhaust Fluid container label.
