Important
12 V terminal
In the event of a total loss of power, the car can't be unlocked as the locks are electrically operated. To access the car and charge it, the car can be powered for a short time using the externally accessible 12 V terminal. It can be accessed by removing a small panel below the front bumper, near the front left wheel.
Before any use of the 12 V terminal, consider the following:
- Polestar recommends that the 12 V terminal is only used by service technicians for the purpose of accessing the car as part of immobilisation recovery.
- Only use a 12 V charger with a maximum charging current below 30 A.
- Connecting any power source that delivers currents higher than 30 A blows the terminal's fuse, thereby disabling it.
- Only use the 12 V terminal for short amounts of time. This is not meant as a way of powering the car continuously.
