Ram 1500/2500/3500: To Start The Engine While In Autostop Mode

While in DRIVE the engine will start when the brake pedal is released or the throttle pedal is depressed. The transmission will automatically reengage upon engine restart. During this transition the brakes will hold the vehicle to avoid undesired vehicle movement.
