Adjusting the Auto-Dim Function of the Rearview Mirror
Bright light from behind the vehicle, for example from the headlights of following vehicles, could reflect in the rearview mirror and door mirrors and cause glare. Use the auto-dim function when light from behind is distracting.
Auto-Dim
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.
The sensitivity level for dimming will affect both the rearview mirror and door mirrors.
To change the sensitivity level of the auto-dim function:
- Tap Settings in the Top view in the center display.
- Tap My Car
Mirrors and Convenience. - Under Rearview Mirror Auto-Dim, 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.
