If the vehicle has a diesel engine it could have an engine idle shutdown feature.
This feature automatically shuts down the engine after it idles continuously for five minutes and if the following conditions are met:
| • | The parking brake is set. |
| • | The vehicle is at a complete stop. |
| • | The automatic transmission is in N (Neutral) or P (Park). |
If the parking brake is not engaged, then the engine shuts down after 15 minutes of continuous idling operation.
The driver can reset the engine shutdown timer by momentarily changing the position of the accelerator, brake, or clutch pedal or by shifting the transmission out of P (Park) or N (Neutral). Once reset, the engine idle shutdown will restart the shutdown sequence described above, and will continue to do so until the engine shuts down or the vehicle is driven.
The engine will not go into idle shutdown mode if:
| • | The Power Take-Off (PTO) equipment is operating. See Power Take-Off (PTO) for more information. |
| • | The engine coolant temperature is below 60° F. The engine idle shutdown will be activated once the vehicle coolant reaches 60°F or above. |
| • | The Diesel Particulate Filter (DPF) is in regeneration mode and the green DPF lamp is illuminated to notify the driver that DPF is regenerating. The engine idle shutdown mode will be overridden for the time necessary to complete the regeneration process, up to a maximum of 30 minutes. |
| • | Service or maintenance is being performed on the engine. The engine idle shutdown mode may be deactivated, by using a diagnostic scan tool, for a period of up to a maximum of 60 minutes. |
The ENGINE SHUTDOWN WARNING LIGHT will come on and a continuous chime will alert the driver 30 seconds before the engine goes into idle shutdown mode. The engine shutdown warning light and chime will stay on for the entire duration of the idle shutdown event to inform the driver that the engine is in idle shutdown mode. See Engine Shutdown Warning Light for more information.
After the engine shutdown occurs, the engine is no longer running, and the ignition is still in the ON/RUN position, all accessories can be used. Turn the ignition switch to START to restart the engine or turn it to LOCK or OFF to prevent the battery from draining.
