Optimized Idle Procedure

p4 dm 03.08.000

Optimized idle can be started with the engine running or the engine off.

  1. With the key on, go to the Cab menu and select Optimized Idle. A caution notice will popup.
  2. Read the caution and press Enable.
  3. A screen may appear to start Standby or another mode. If this is the only option, press Enable.
  4. Otherwise a screen will appear with an Enable with Comfort button as an option. If you want to optimize the environment of the sleeper section, select the Enable with Comfort button.
  5. The vehicle will go into standby mode, an under hood alarm will briefly sound, and the engine will crank and achieve 900 rpm. The screen will change to the selected mode. A Disable button will be present.
  6. The engine and fan/air conditioning will run until it achieves the temperature requested by the driver. The engine will then shut down.
    Optimized idle can be shut off by ICUC controls or pressing the brake. If the sleeper fan is turned off, optimized idle will not shut down but the engine will.
