CONTROLS AND INSTRUMENTS
WARNING
• Run the engine at standard idling speeds before driving.
• Driving the vehicle with idling speeds higher than normal is dangerous because
it could cause abrupt forward movement. It will also consume more fuel during
subsequent driving and shorten the clutch life.
ADVICE
• The idling control switch is used to increase the efficiency of the heater and/
or the defroster during engine idling, or to manually increase the engine idle
speed.
NOTE
• The idling speed will not be accurate in the following conditions:
- When the engine coolant temperature is low
- When the power take-off (PTO) is operating if your vehicle is equipped with a
PTO
Idling Control Switch
This switch adjusts the idling speed when
warming up the engine. The engine speed
will rise when the "+" side of the switch is
pressed. After the engine is warmed up,
press the "-" side to fully reduce the engine
speed.
While the vehicle is stationary, the idling
speed cannot be adjusted with this switch
unless the gearshift lever is in the "N"
position.
If the idling speed is not within the standard
values, or the engine does not smoothly
turn over, contact the nearest Isuzu Dealer.
Standard idling speed
450 - 500 r/min
