Important safety notes

WARNING
It is dangerous to shift the automatic transmission out of parking position P or neutral position N if the engine speed is higher than idle speed. If your foot is not firmly on the brake pedal, the vehicle could accelerate quickly forward or in reverse. You could lose control of the vehicle and hit someone or something. Only shift into gear when the engine is idling normally and when your right foot is firmly on the brake pedal.

WARNING
Keep in mind that turning off the engine alone only will shift the automatic transmission into neutral position N automatically.
Always shift the automatic transmission into park position P before turning off the engine.
Otherwise the vehicle could roll away which could result in an accident and/or serious personal injury.
