CONTROLS - Settings Level 1 Engine Derate The Level 1 Engine Derate is a suppressible pop-up and audio "beep" that is displayed when the ECU determines that engine power should be reduced to protect it from damage. A Level 1 Derate will reduce engine output by 25 percent. Settings NOTE Various settings may be changed using this function. The operator can change the time format (12hr/24hr), the time of day and alarm settings, units of measure for the display (mile/kilometer), display mode and the language being displayed. This menu is available only when the vehicle is parked.
There are times when the “Display Off” mode is not allowed or over-ridden by the system, for example if a “pop-up” message appears, the screen will turn back on, or if the truck is equipped with an adaptive cruise control system, the screen cannot be turned off when it is active. Increased Derate This message is a suppressible pop- up that warns the operator how much time remains before a Level 2 engine derate will occur. Once the popup is suppressed the popup will re-occur every 15 minutes to remind the operator of upcoming derate. 3 Level 2 Engine Derate The Level 2 Engine Derate is a NON- suppressible pop-up and has a continuous audio tone, until the vehicle is parked.
It is displayed when the ECU determines that engine power should be reduced to protect it from damage. A Level 2 Derate will reduce engine output by 40 percent. Changing settings functions are typically done one of two ways. Items can be toggled straight from the highlighted selection (at the branch level); these cases use dark blue text that changes to the set value. Others are menu selections that bring up new “leaf level” screens. The following shows examples of turning the alarm on/off vs. screens that are navigated to in order to set the clock time.
