Adjust the mirror so that you can see the entire rear of the car in the mirror.
To reduce glare from headlights of a vehicle behind you when driving at night, use the control lever on the lower edge of the mirror.
Driving in daylight – the lever is in position 1. In this position the reflection is clearer.
Driving at night – the lever is in position 2.
Remember that as glare decreases, rear visibility is somewhat reduced.
