EXPLANATION OF COMPONENTS
When stopping the engine during regeneration of the aftertreat-
ment devices, stop the regeneration first, then stop the engine
after running it at low idle for approximately 5 minutes.

DEF low level guidance
If the operable time estimated from the current DEF level and
the latest average DEF consumption is shorter than 8 hours,
the low DEF level message is displayed.
The low DEF level message goes out more than 10 seconds
after or when switch F5 is pressed.
METER DISPLAY
ENGINE COOLANT TEMPERATURE GAUGE
Engine coolant temperature gauge shows the engine coolant
temperature.
If the indicator is in green range during operations, it is normal.
When the indicator goes beyond (A) of red range during opera-
tions, the overheat prevention system is actuated.
(A) to (B): Red range
(A) to (C): Green range
(C) to (D): White range
The overheat prevention system is actuated as follows.
Red range (A) position: Engine coolant temperature caution
lamp (E) shows abnormality display.
Red range (B) position: Engine speed changes to low idle, engine coolant temperature caution lamp (E) shows
abnormality display and alarm buzzer sounds at the same time
The overheat prevention system continues to operate until the indicator enters the green range.
When the engine is started, if the indicator is at position (D), engine coolant temperature caution lamp (E) shows
the low-temperature display.
In this case, perform warm-up operation. For details, see "METHOD FOR ENGINE WARM-UP OPERATION".
