Important safet ynotes G
WARNING
Never depress the brake pedal continuously
while the vehicle is in motion ,e.g. never cause
the brakes to rub by applying constant slight
pedal pressure. This causes the brake system
to ove rheat, increases the braking distance
and can lead to the brakes failing completely. G
WAR
NING
Do not change down for additional engine
braking on aslippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. G
WARNING
SPEEDTRONIC is only an aid designed to
assist driving. You are responsible for the
vehicle's speed and for braking in good time. G
WARNING
If ther eisac hange of drivers, advise the new
drive rofthe limit speed stored.
Only use variable SPE EDTRONI Cifyou will not
have to accelerate suddenl ytoaspeed above
that stored as the limit speed. You could oth-
erwise cause an accident.
You can only exceed the limit speed stored if
you deactivate variable SPE EDTRONIC:
R using the cruise control lever
R by depressin gthe accelerator pedal
beyon dthe pressure point (kickdown)
It is not possible to deactivate variable

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
