Volvo S90 2019 Owner's Manual page 171

The rearview mirror instead has two sensors -
one pointing forward and one pointing rear-
ward - which work together to identify and
eliminate glare. The forward-pointing sensor
monitors ambient light, while the rearward-
pointing sensor monitors light from the head-
lights of following vehicles.
For the door mirrors to be equipped with auto-
dim, the rearview mirror must also be equip-
ped with auto-dim.
NOTE
If the sensors are obstructed by e.g. a
parking permit, transponder, sunshade or
objects on the seats or parcel shelf in a
way that prevents light from reaching the
sensors, the auto-dim function in the rear-
view and door mirrors will be reduced.
