When you lock the car, some of its functions and systems are either shut down or activated to help protect the car from theft. For example, the alarm is automatically armed.
Warning
Alarm
The alarm is automatically armed when you lock the car and disarmed when you unlock it.
You can adjust the alarm sensitivity in settings.
Immobiliser
The immobiliser is an anti-theft system that prevents your car from being driven until it is started using a valid key. If your car can't find the key or fails to authenticate it, your car will remain immobilised. A notification appears in the display if the key can't be found or has a low battery. If your car is unresponsive to a battery-powered key, try using a key card. If the car appears to have no power, the cause could be flat batteries or something affecting its electrical systems.
Steering wheel lock
Your car's steering wheel lock is automatically engaged when you lock the car. This is to prevent unauthorised driving of your car, such as if it's stolen. When you unlock your car, the steering wheel is also unlocked.
Double lock
The double lock feature allows you to simultaneously lock your car from the outside and the inside. This is to prevent unauthorised attempts to open the car using the inner door handles.
There isn't a specific setting to activate or enable double locking. For double locking to take effect, you need to disable the reduced alarm setting and then lock the doors as usual. The double lock system then activates after a few seconds.
Warning
Volvo recommends not leaving people or pets in a locked car. 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.
Note
Presence warning
By default, the car alerts you when it suspects that there are occupants in the car when locking. When this happens, the car will not activate the double lock. This is intended to help you be more aware of and responsibly use double locking.
