opti idle for international truck????

You have to have the sleeper pretty heated prior to turning on the apu. So idle it up and crank the heat till it gets nice and toasty. Shut off the engine and set your temp at what you want and you should be sweating your acorns off before you know it!☺

 

Turn truck on. If you have the controls on the dash push them both up till they are running in the back for a minute. It will show the levels where the odometer is. Once they are set, turn truck off and immediately go in to the sleeper and push the heater button so the green light comes on. This will start the heat to continue. Now you can adjust the levels in the sleeper.
