Always pay attention to traffic conditions
even when DISTRONIC PLUS is activated.
Otherwise, you may fail to recognise dangers
in time, cause an accident and injure yourself
and others.
The radar sensor system is switched off auto-
matically in the vicinity of radio telescope
facilities ( page 375).

If you want DISTRONIC PLUS to assist you,
the radar sensor system must be activated
( page 242) and operational.

If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control in the speed range between
30 km/h and 200 km/h. If a vehicle is driving
in front of you, DISTRONIC operates in the
speed range between 0 km/h and
200 km/h.
Do not use DISTRONIC PLUS on roads with
steep gradients.

WARNING
DISTRONIC PLUS brakes your vehicle up to a
2
maximum of 4 m/s
This corresponds to approximately 40% of
your vehicle's maximum braking power. You
must also apply the brakes yourself if this
braking power is not sufficient.
If DISTRONIC PLUS detects a risk of collision
with a vehicle in front, an intermittent warning
tone sounds. In addition, the · distance
warning lamp in the instrument cluster lights
up. Brake to avoid a collision.
