the brakes from overheating and wearing too
quickly.
If a slower-moving vehicle is detected in front,
DISTRONIC PLUS causes your vehicle to
brake and maintain a preset distance to the
vehicle in front.
G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid.
G
Risk of accident
DISTRONIC PLUS is only an aid designed to
assist driving. The driver remains fully respon-
sible for the vehicle's distance from other
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
Risk of accident
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 324).
Y
If you want DISTRONIC PLUS to assist you,
the radar sensor system must be activated
( page 208) 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 while driving on
roads with steep gradients.
G
Risk of accident
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
Driving systems
depending on its speed.
