Double lock
The double lock feature allows you to simultaneously lock the doors from the outside and the inside.
The double lock feature is intended as an anti-theft system. When enabled, the double lock system activates a few seconds after the car is locked from the outside. Once the car is double-locked, it can't be unlocked from the inside.
Note
For safety reasons, the car will not double lock when the occupant detection system senses that someone is still inside the car.
Warning
Volvo recommends not leaving people or pets in a locked car. By allowing occupant locking it will be possible to lock the car even when it has detected people or pets inside. Certain car systems will remain active and the car doors can still be opened from inside. The driver remains responsible for the well-being and safety of anyone left in the car. Some regions have laws prohibiting people or pets being left inside a locked vehicle.
