Engine Shutdown
Note: If parking the vehicle for more than two days, turn the cab load disconnect switch (CLDS) to the OFF position.
If parking the vehicle for more than two days and the vehicle is not equipped with a CLDS, or if parking the vehicle for more than five days, disconnect the batteries.
Even with the CLDS off, the vehicle draws a small amount of battery power.
Disconnecting the batteries when parking the vehicle for extended periods prevents battery discharge and helps prolong battery life.
- With the vehicle stopped, set the parking brake and place the transmission in neutral.
- Allow the engine to idle one to two minutes before shutting it down. This allows the lubricating oil and the coolant to carry heat away from the combustion chambers, bearings, shafts, and seals.
- Turn off the ignition switch and shut down the engine.
Notice: Idle the engine one to two minutes before shutting it down. After hard operation, shutting down the engine without idling may cause damage to the turbocharger.
