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.

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.
