Display
Lamp in the exterior mirror housing
Prewarning
The dimmed lamp in the exterior mirror hous‐
ing indicates when there are vehicles in the
blind spot or approaching from behind.
Acute warning
If the turn signal is set while a vehicle is in the
critical zone, the steering wheel vibrates briefly
and the lamp in the exterior mirror housing
flashes brightly.
The warning stops when the turn signal is
switched off, or the other vehicle leaves the
critical zone.
Brief flashing
A brief flashing of the lamp during vehicle un‐
locking serves as system self-test.
