OPERATING OPTIMIZED IDLE
The following conditions must be met to activate Optimized Idle:
• The ignition switch must be in the “ON” position and the engine idling
• Hood, cab, or engine compartment door(s) closed
• Transmission in neutral and in high--range (if equipped)
• Park brake set
• Idle Shutdown Timer must be enabled
NOTE:
Keep vehicle park brake properly maintained.
If this vehicle is equipped with Cruise Control, the Cruise Master Switch must be
moved to the “ON” position after the vehicle is idling and the above conditions are
set. If the Cruise Master Switch is on prior to the vehicle idling, turn it to “OFF.”
Turn the Cruise Master Switch to “ON” after the vehicle is idling and the above
conditions are met.
NOTE:
To disable Optimized Idle, turn off the ignition, turn the Cruise
Master Switch OFF, or use the drive away feature (Section 6, Refer to
section "DRIVE AWAY"). If the engine is not running, pressing the clutch
(optional) will disable Optimized Idle. The Optimized Idle active light is on
when Optimized Idle is active.
NOTE:
The transmission lever should not be moved while Optimized Idle is
active, since this could disable Optimized Idle. If the lever is moved, verify
that the transmission is not in gear and that Optimized Idle is still active.
The engine compartment alarm sounds briefly prior to any Optimized Idle engine
start. After Optimized Idle starts the engine, the speed will be increase to the
parameterized target RPM (default = 1000, 900 if equipped with Clean Idle option).
Once the above conditions are met:
• The Optimized Idle active light will flash
• The active light will stop flashing and stay on after the idle shutdown timer
expires
The Optimized Idle active light flashing indicates that Optimized Idle will begin
operation after the idle shutdown timer expires. When the active light stops flashing
and stays on (after the idle shutdown timer expires) the operator can no longer use
other DDEC features, including the foot pedal. This condition continues until the
park brake is released, the hood or engine compartment door(s) is opened, the
transmission is put in gear, or the Cruise Switch is turned off. Optimized Idle may
continue to run the engine to warm--up the engine, or heat (cool) the interior.
Optimized Idle will shut down the engine when the battery voltage, engine
temperature, or cab temperature values are met. The engine will restart only when
the ECM determines that the engine needs to start to charge the battery, warm the
engine, or heat (cool) the interior.
