Auto Neutral

sdp dm 14.02.013

Warning: Do not leave the driver’s seat without placing the shift stalk lever in the neutral position and applying the parking brake, failure to do so could cause property damage and personal injury.

General Information, Auto Neutral Feature

The auto neutral feature will shift the Detroit transmission into neutral if the drive direction switch is left in drive or reverse for an extended period of time. The driver is warned of a pending shift with a flashing ‘N’ in the gear position display of the instrument cluster. A brief warning buzzer will sound when the transmission shifts into neutral. See  for all the conditions and indicators that are possible.

Note:  If the auto neutral feature is activated, apply the service brake and cycle the gear direction switch into neutral, and back into the desired position.

Additionally for vehicles equipped with CPC3Evo, if the engine is shutdown without the drive direction switch in the 'N' position, the warning buzzer will provide a long duration activation, and a pop-up will prompt the driver to place the shifter into the neutral position.

Warning: If the transmission doesn't achieve neutral before shutdown, it will not restart until it can complete the shift to neutral.

If neutral gear is not achieved, a pop-up encourages the driver to start the engine to allow the transmission to achieve neutral gear.
