Engine Low Temperature Regulation; Def/Adblue® Freeze Warning - Kubota M5N-091 Operator's Manual

BEngine Low Temperature Regulation
In order to prevent engine damage due to rapid
acceleration, if starting the engine when coolant
temperature is approximately 0°C (32°F) or below, the
engine rpm will be kept at approximately 1400 for up to 3
minutes, and the operator will be informed by indicator
and intermittent buzzer. The regulation time varies in
response to the coolant temperature.
During regulation, perform warm-up operation without
using the accelerator. After regulation, the engine rpm can
be gradually increased. When regulation has been
completely released, the indicator will go off and the
buzzer stop.

BDEF/AdBlue® Freeze Warning
[M5N-091, M5N-111]
When operating in cold weather, the DEF/AdBlue® is
automatically thawed while the engine is running.
However, in weather conditions of under -30
the DEF/AdBlue® cannot be completely thawed and thus,
an error/warning code (P208B) appears on the instrument
panel's LCD screen.
If the error/warning code (P208B) appears on the screen,
stop the engine and restart it after 10 seconds. After
restarting the engine, the error/warning code(P208B) will
disappear and the thawing of the DEF/AdBlue® will
resume.
In case the error/warning code (P208B) remains on the
screen even after restarting the engine several times,
contact your local KUBOTA Dealer.
