Warning: Do not leave the vehicle unattended with the engine running. If you leave the vehicle and the engine is running, the vehicle can move suddenly, which could result in personal injury or property damage.

On vehicles with MD series transmissions, do the following steps if you have to leave the cab with the engine running (for example, when checking the transmission fluid):

  1. Bring the vehicle to a complete stop using the service brake.
  2. Put the transmission in N (neutral).
  3. Ensure that the engine is at low idle (500 to 800 rpm).
  4. Apply the parking brake and emergency brakes, and make sure they are properly engaged.
  5. Chock the rear tires and take any other steps necessary to keep the vehicle from moving.
