Ensure the vehicle is parked in a safe location.
Make sure the vehicle is in "Park" mode.
Verify that you have the latest version of the Tesla app and that your phone is charged.

Open the front trunk (frunk) to access the 12V battery.
Using a multimeter, check the voltage of the 12V battery; it should be around 12.6V or higher.
If the voltage is low, consider replacing the 12V battery.
