If your truck is equipped with optimized idle, this is one of the few procedures procedures: Make sure the parking brake is set, hood is latched, transmission in neutral Turn the ignition on or start the engine Double tap the button with the 2 squares icon (on the right hand side of the steering wheel) A Caution prompt. Freightliner recently downgraded their AC compressors, both replacement units and new-build units. The old units worked well at 600 RPM. The new units need around 900 RPM to work properly. If you have a new model AC compressor and opti-idle is set for 600 RPM, it is very likely that the method described above will not work consistently.

Same principle, Opti-Idle runs the engine as needed to maintain the main engine starting and running and the temp in the cab and sleeper. The hotter or colder it is outside, the more the engine will run to maintain those conditions Cummins has something similar, Opti-Idle was inflicted on us by Detroit, and I have never had a truck equipped.. This is what optimized idle mode is for. The procedure to use it is below. . . Decided to just post the procedure: With the engine on, crank the heat or AC to where you want it and allow the engine to auto shut down. This will "season" the cab temperatures. On the steering wheel scroll to optimized idle and press okay.
