Replacing the key's battery

The battery in the key must be replaced when it is discharged.

 Note

All batteries have a limited service life and must eventually be replaced. The battery's service life varies depending on how often the vehicle/key is used.

The key battery should be replaced if
  • the information symbol illuminates and the message Vehicle key battery low See Manual is displayed in the instrument panel

 Note

Move closer to the vehicle and try to unlock it again.

The battery in the buttonless key (Key Tag) cannot be replaced – contact Polestar Customer Support.

 Warning

  • Keep batteries out of reach of children.
  • Do not leave batteries lying about where they could be swallowed by children or pets.
  • Never dismantle, short-circuit or throw a battery into an open flame.
  • Do not charge non-rechargeable batteries, as this could cause them to explode.

Make sure the key is undamaged before use. If any damage is detected, for example, if the battery cover doesn't close properly, the product should not be used. Keep defective products out of the reach of children.

 Important

Be sure to dispose of end-of-life batteries in a way that protects the environment.
