WARNING
DISTRONIC PLUS canno ttake account of road
and traffic conditions. If DISTRONI Cdoes not
recognise or no longer recognises the vehicle
in front, do not activate DISTRONIC or, if it is
alr eady active, deactivate it. This is especially
the case:
R befor ecorners
R on filter lanes
R when changing to alane with faster moving
traffic
R in comple xdriving situations or where lanes
are diverte d,e.g. at roadworks on amotor-
way
DISTRONIC PLU Sotherwise maintains the
current spe ed setbyyou or accelerates up to
the set speed.
DISTRONIC PLU Scannot take account of
weather conditions. Deactivate, or do not
activate, DISTRONI CPLUS:
R if th eroads are slippery, snow-covered or
icy .The wheels coul dlose their grip when
brakin goraccelerating .The vehicle could
star ttos kid.
R if the sensors are dirty or there is poo rvis-
ibility, e.g. due to snow, rain or fog. Dis-
tance control may be impaired.
Always pay attention to traffic conditions
even when DISTRONIC PLU Sisactivate d.
Otherwise, you ma yfail to recognise dangers
in time, caus eanaccident and injure yourself
and others. G
WARNING
DISTRONIC PLUS brake syourvehicle up to a
maximu mof4m /s2
depending on its speed.
This corresponds to approximately 40% of
your vehicle's maximum braking power. You
must als oapply the brakes yourself if this
braking power is not sufficient.
If DISTRONI CPLUS detects arisk of collision
with avehicle in front, an intermit tent warning
tone sounds. In addition, the ·distance
warning lamp in the instrument cluste rlights
up. Brak etoavoidac ollision. G
WAR
NING
The vehicle can be braked when DISTRONIC
PLUS is activated. For this reason, deactivate
DISTRONIC PLUS if the vehicle is to be set in
motion by othe rmeans (e.g. in acar wash or
by towing).
The radar senso rsystem is automatically
deactivated near radio teles cope facilities
(Y page 38 0).
If you want DISTRONIC PLUS to assist you,
the radar sensor syste mmust be activated
(Y page 249 )and operational.
General notes DISTRONIC PLUS regulates the speed and
automati cally helps you maintain the dis-
tanc etot he vehicle detected in front. It
brakes automatically in orde rtoavoid
exceedi ngthe set speed.
On long and stee pdownhil lgradients, espe-
ciall yifthe vehicle is laden or towing atrailer,
yo um ust select shift range 1,2or 3in good
time. By doing so, you will make use of the
braking effec tofthe engine. This relieves the
load on the brake system and prevents the
brakes from overheating and wearing too
quickly.
If DI STRONIC PLUS detects aslower-moving
vehicle in front ,your vehicle is braked in order
to maintain the preset distance to the vehicle
in front.
If ther eisnov ehicle in front ,DISTRONIC
PLUS operate sinthe sam eway as cruise
control in the spee drange between
30 km/h and 200 km/h. If avehicle is driving
in fron tofyou, DI STRONIC operates in the
speed range betwee n0km/h and
200 km/h.

WARNING
If you depres sthe brake, DI STRONIC PLUS is
deactivated unless your vehicle is stationary.
DISTRONIC PLUS then no longe rbrake syour
vehicle. In such cases, control the distance
from vehicles travelling in front with the brake
alone. You coul dotherwis ecause an accident
and thereby injure yourself and others. The
driver remains fully responsible for the vehi-
cle's distance from other vehicles, the speed
being driven and for braking in good time.
If there is no vehicle in front ,DISTRONIC
PLUS operate sinthe sam eway as cruise
control.
If DISTRONIC PLUS detect sthat the vehicle
in front has slowed down, it brakes your vehi-
cle. In this way ,the distanc eyou have selec-
ted is maintained.
If DI STRONIC PLUS detects afaster-moving
vehicle in front ,itaccelerates your vehicle,
but only up to the speed you have stored. Changing lanes
If you wis
htochange to the passin glane (in
countries where traffic drives on the right, the
passing lane is the left-hand lane), DIS-
TRONIC PLUS supports you if:
R you are driving faster than 60 km/h.
R DISTRONIC PLUS is maintainin gthe dis-
tan cetoav ehicle in front.
R you switc honthe appropriate tur nsignals.
R DISTRONIC PLU Sdoes not detec tadanger
of collision.
If these conditions are met, your vehicle is
accelerated. Acceleration will be interrupted
if changin glanes takes too long or if the dis-
tanc ebetween your vehicle and the vehicle in
front becomes too small. G
WARNING
DI ST RONIC PLUS and Active Blind Spot Assist
are only an aid designed to assist driving.
The ydon ot relieve you of the responsibility
of payin gattention. The driver remains fully
responsibl efor the vehicle' sdistance from
other vehicles, the vehicle's speed and for
braking in good time. Always pay attention to
traffic conditions and your surroundings. Oth-
erwise, you may fail to recognise dangers in
time, cause an accident and injur eyourself
and others.
