Indicator and warning display
1 Yellow indicator lamp/red warning lamp
When Blind Spot Assist is activated, indicator lamp 1 lights up yellow in the exterior mirrors up to a vehicle speed of 20 mph (30 km/h). When the vehicle speed exceeds 20 mph (30 km/h), the indicator lamp goes out and Blind Spot Assist is ready for use.
When your speed exceeds approximately 20 mph (30 km/h), warning lamp 1 lights up red on the corresponding side whenever a vehicle is detected in the blind spot monitoring range. This warning is always given when a vehicle enters the blind spot monitoring range from behind or from the side. When you are passing another vehicle, the warning is emitted only if the difference in speed is less than 7 mph (12 km/h).
The yellow indicator lamp goes out if the reverse gear is engaged. In this event, Blind Spot Assist is no longer active.
The brightness of the indicator/warning lamps is adjusted automatically according to the ambient light.
WARNING 
Blind Spot Assist is not active at speeds under
approximately 20 mph (30 km/h). The
indicator lamps in the exterior mirrors are
yellow. Vehicles in the monitoring range are
then not indicated.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognize dangers in time, cause an accident
and injure yourself and others.
