Enabling automatic dimming

Bright lights, such as other vehicle headlights, can reflect in the rearview mirror. This can cause glare, but your vehicle's automatic dimming counteracts this.

Enable automatic dimming to avoid being distracted by light from behind. For everyone's safety and for your comfort, make sure that you activate it before you start driving. You turn it off in the same way that you turn it on.

 Note

If the light sensors in the rearview mirror are obstructed in a way that prevents light from reaching them, the automatic dimming effect will be reduced. For example, parking permits or sunshades placed high up on the windshield could stop light from reaching the sensors.
Press the vehicle symbol on the bottom bar and go to Settings.
Go to Controls → Mirrors and wipers → Auto dim rear view mirror.
Turn it on or off.
