ference) between the speed of the vehicle
ahead and the set speed comes on.
If Distronic calculates that there is a dan-
ger of collision ( page 216):
The distance warning lamp l in the
instrument cluster comes on.
An intermittent warning sounds.
Immediately brake the vehicle to avoid
a collision.
Under no circumstances should the
driver await the intermittent warning
sound before braking.

lamp l goes out when the neces-
sary distance to the vehicle ahead is
again established.
