If the control levers are at neutral, this switch (2) automatically
lowers the engine speed and turns on the function to reduce fuel
consumption.

Auto-deceleration function
When the auto-deceleration function is ON, if the work
equipment control and travel levers are returned to the N
position, the engine speed will drop after 4 seconds from the
operating speed to idle speed.
This makes it possible to reduce fuel consumption.
If any lever is operated when the machine is in this condition,
engine speed will return to the previous operating speed to
make it possible to perform operations.

auto-deceleration function is turned ON, the mode is displayed

screen returns to the standard screen.

up.
(When the auto-deceleration is OFF, it does not light up.)
