Distronic displays in the speedometer
1
Set speed
If the Distronic is activated, one or two cruise
control speed segments come on around the
set speed.
The vehicle speed displayed on the
speedometer can briefly vary from the speed
setting on the Distronic system.
1

Cruise control speed segments
3
Speed of the vehicle ahead
If the Distronic detects a vehicle directly
ahead, the cruise control speed segments
2 appear in the speedometer. These
segments represent the difference between
the set speed of your vehicle 1 and the
speed of the preceding vehicle 3.
If the Distronic calculates that there is a
danger of collision, the distance warning lamp
l in the instrument cluster comes on and
an intermittent warning sounds.
X
Immediately apply the brakes to avoid a
collision.
Under no circumstances should the driver
await the intermittent warning sound
before braking.
The intermittent warning sound ceases and
the distance warning lamp l goes out
when the necessary distance to the vehicle
ahead is established again.
G
Warning!
An intermittent warning sounds and the
distance warning lamp l in the
instrument cluster is illuminated if the
Distronic system calculates that the
distance to the vehicle ahead and your
vehicle’s current speed indicate that the
Distronic will not be capable of slowing the
vehicle sufficiently to maintain the preset
following distance, which creates a danger
of a collision.
Immediately brake the vehicle to increase
your distance to the preceding vehicle. The
warning sound is intended as a final caution
in which you should intercede with your
own braking inputs to avoid a potentially
dangerous situation. Do not wait for the
operation of the warning signal to intercede
with your own braking. This will result in
potentially dangerous emergency braking
which will not always result in an impact
being avoided.
Tailgating increases the risk of an accident.
