When you finish driving, simply exit the vehicle. When you leave Model S with your phone key and key fob, it powers off automatically, turning off the instrument panel and touchscreen.
Model S also powers off automatically after being in Park for 30 minutes, even if you are sitting in the driver's seat.
Although usually not needed, you can power off Model S while sitting in the driver's seat, provided the vehicle is not moving. Touch Controls > Safety > Power Off. Model S automatically powers back on again if you press the brake pedal or touch the touchscreen.
NOTE: Model S automatically shifts into Park whenever it determines that you are exiting the vehicle (for example, the driver's seat belt is unbuckled and the vehicle is almost at a standstill). If you shift into Neutral, Model S shifts into Park when you open the door to exit. To keep Model S in Neutral, see Instructions for Transporters.
Power Cycling the Vehicle
You can power cycle Model S if it demonstrates unusual behavior or displays a nondescript alert.
NOTE: If the touchscreen is unresponsive or demonstrates unusual behavior, reboot it before you power cycle the vehicle (see Restarting the Touchscreen).
1. Shift into Park.
2. On the touchscreen, touch Controls > Safety > Power Off.
3. Wait for at least two minutes without interacting with the vehicle. Do not open the doors, touch the brake pedal, touch the touchscreen, etc.
4. After two minutes, press the brake pedal or open the door to wake the vehicle.
