2. The engine RPM will go up to 1100 RPM. To increase
the RPM, press and hold the ACCEL/RESUME switch
and the idle speed will increase to approximately 1500
RPM. To decrease the RPM, press and hold the DECEL
switch and the idle speed will decrease to approximately
1100 RPM.
3. To cancel the Idle–Up feature, either press the CAN-
CEL switch, press the ON/OFF switch, or press the brake
pedal.
Stopping The Engine
Idle the engine a few minutes before routine shutdown.
After full load operation, idle the engine three to five
minutes before shutting it down. This idle period will
allow the lubricating oil and coolant to carry excess heat
away from the combustion chamber, bearings, internal
components, and turbocharger. This is especially impor-
tant for turbocharged, charge air-cooled engines.
NOTE:
•
During engine shut down on vehicles equipped with
manual transmissions, it is normal for the diesel
engine to resonate heavily for a moment during engine
shut off. When the engine is connected to a manual
transmission, this resonance causes load gear rattle
from the transmission. This is commonly referred to as
“shut down rattle.” The manufacturer recommends
performing engine shut down with the clutch pedal
pushed to the floor (clutch disengaged). When engine
shut down is performed in this manner the rattle is
reduced (not eliminated).
