Volvo XC90: Lighting / Adjusting the rearview mirror dimming function

Bright light entering the vehicle from behind, e.g. from the headlights of following vehicles, could reflect in the rearview mirror and door mirrors and cause a glare. Use the dimming function when light from behind is distracting.


If bright light enters the vehicle from behind, the door mirrors will automatically dim when it is dark outside or when lighting conditions are low, for example when driving in tunnels. Auto-dim is always active when the engine is running, except when reverse gear is engaged.


Adjustments to the sensitivity level will not be noticeable immediately but will instead take effect after a short period of time.

The sensitivity level for dimming will affect both the rearview mirror and door mirrors.

To change the dimming sensitivity level:

  1. Tap Settings in the Top view in the center display.
  2. Tap My Car Volvo XC90. Adjusting the rearview mirror dimming function Mirrors and Convenience.
  3. Under Rearview Mirror Auto Dimming, select Normal, Dark or Light.

The rearview mirror has two sensors - one pointing forward and one pointing rearward - which work together to identify and eliminate glare. The forward-pointing sensor monitors ambient light, while the rearward-pointing sensor monitors light from the headlights of following vehicles.

For the door mirrors to be equipped with autodim, the rearview mirror must also be equipped with auto-dim.


If the sensors are obstructed by e.g. a parking permit, transponder, sunshade or objects on the seats or in the cargo compartment in a way that prevents light from reaching the sensors, the auto-dim function in the door and rearview mirrors will be reduced.
