vehicles, the vehicle's speed and for braking
in good time.
DISTRONIC PLUS does not react in particular
to:
pedestrians
R
stationary obstacles on the road, e.g. stop-
R
ped or parked vehicles
oncoming and crossing traffic
R
DISTRONIC PLUS may not detect narrow vehi-
cles driving in front, e.g. motorcycles, or vehi-
cles driving on a different line. Therefore,
always pay attention to traffic conditions even
when DISTRONIC PLUS is activated. Other-
wise, you may fail to recognise dangers in
time, cause an accident and injure yourself
and others.
G WARNING
DISTRONIC PLUS cannot take account of road
and traffic conditions. If DISTRONIC does not
recognise or no longer recognises the vehicle
in front, do not activate DISTRONIC or, if it is
already active, deactivate it. This is especially
the case:
before corners
R
on filter lanes
R
when changing to a lane with faster moving
R
traffic
in complex driving situations or where lanes
R
are diverted, e.g. at roadworks on a motor-
way
DISTRONIC PLUS otherwise maintains the
current speed set by you or accelerates up to
the set speed.
DISTRONIC PLUS cannot take account of
weather conditions. Deactivate, or do not
activate, DISTRONIC PLUS:
if the roads are slippery, snow-covered or
R
icy. The wheels could lose their grip when
braking or accelerating. The vehicle could
start to skid.
if the sensors are dirty or there is poor vis-
R
ibility, e.g. due to snow, rain or fog. Dis-
tance control may be impaired.
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 automatically
deactivated near radio telescope facilities
( page 398).
Y
If you want DISTRONIC PLUS to assist you,
the radar sensor system must be activated
( page 247) and operational.
Y
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.
G
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.
Cruise control lever
With the cruise control lever, you can operate
DISTRONIC PLUS and variable SPEED-
TRONIC.
The LIM indicator lamp on the cruise control
lever indicates which system you have selec-
ted:
