ST RONIC PLUS has not detected the vehi-
cle cutting in yet. The distance to this vehicle
will be too short.
Narrow vehicles DISTRONIC PLUS has not yet detected the
vehicle in fron tonthe edge of the carriage-
way, because of its narrow width. The dis-
tance to the vehicle in front will be too short.
Obstruction sand sta tionary vehicles DISTRONIC PLUS does not brake for obsta-
cles or stationary vehicles. If, for example, the detected vehicle turns
acorner and reveals
an obstacle or stationar yvehicle, DI STRONIC
PLUS will not brake for these.
Crossin gvehicles DISTRONIC PLUS may mistakenly detect
vehicles that are crossing your lane. Activat-
ing DISTRONIC PLUS at traffic lights with
crossing traffic, for example, could cause
your vehicle to pull away unintentionally.

Important safety notes G
WARNING
Make sure that nobody is near the wheel arch
or vehicle underside when you make achange
to the vehicle level. Otherwise, you or others
ma ybet rapped. G
WARNING
Always select as lo wavehicle level as possi-
ble. If the vehicle level is high, the vehicle
centre of gravity shifts upwards. This increa-
ses the risk of the vehicle tippin gover.
Adapt you rdriving style to suit th evehicle
level. ESP ®
cannot reduc ethe risk of an acci-
dent if you drive too fast. ESP ®
cannot over-
rid ethe laws of physics.
! When driving on extremel yrough terrain,
select ahigh vehicle level in good time.
Make sure there is always sufficient ground Drivin

and audible collisio nwarning. For monitoring,
Active Blin dSpot Assist uses sensors in the
rear bumper.
For Blin dSpot Assist to assist you when driv-
ing, the rada rsensor system must be activa-
ted (Y page 283) and operational.
The rada rsensor system is switched off auto-
maticall yinthe vicinit yofradio telescope
facilities (Y page 433).
Monitoring range of the sensors G
WARNING
Blind Spot Assist monitors certain areas in the
immediate vicinit yofyour vehicle. Vehicles
that approach and driv epast at high speeds
are not detected. There is no display and no
warning.
If the lanes are very wide, it may not be pos-
sible to monitor the complete width of the
neighbouring lane. For this reason, vehicles in
the next lane may not be detected, especially
if they are driving in astaggered formation in
different lanes .This ma ybethe case if vehi-
cles ar edriving at th eedge of their lane that
is furthest away from your vehicle.
Alway spay attention to traffic conditions and
your surroundings. Otherwise ,you may fai lto
recognis edangers in time, cause an accident
and injure yourself and others. Blind Spot Assis
tmonitors the area up to
3. 0mb ehind your vehicle and direc tlyn extto
your vehicle, as shown in the diagram.
If the lanes are narrow, vehicles drivin gint he
lan ebeyond th elan en ext to your vehicle may
be indicated, especially if th evehicles are not
drivin gint he midd le of their lane. This may
be th ecase if there are vehicles at th eedge
of their lan eneares tyour vehicle.
Due to th enature of th esystem:
R warnings may be issued in error when driv-
ing close to crash barriers or similar solid
lane borders.
R warnings may be interrupted when driving
alongside long vehicles, for example lor-
ries, for aprolonged time.
Th et wo radar sensors for Blin dSpot Assist
are integrated int othe sides of the rear
bumper .Make sure that the bumper is free of
dirt, ice or slush in the vicinity of the sensors.
The sensor smust not be covered, for exam-
ple by cycle racks or overhanging loads .Fol-
lowin gasevereimpact or in th eevent of dam-
ag etot he bumpers, hav ethe function of the
sensor schecked at aqualified special ist
workshop. Blind Spot Assist may otherwise
not work properly.

tsafety notes G
WARNING
Active Blind Spo tAssist is only an aid and may
detect vehicles/obstacles incorrectly or not
at all.
The system ma ybeimpaired or may not func-
tio nif:
R there is po orvisibility ,e.g. due to snow,
rain, fog or spray.
R the rear and/or front sensors are dirty.
Active Blind Spot Assist may not detect nar-
row vehi cles, such as motorcycles or bicycles,
or only detect the mtoo late. It can notd etect
vehicles which are overtaken at asmall dis-
tance and then enter th eblind spot area.
Active Blind Spot Assist cannot detect road
and traffic conditions. It is not asubstitute for
attentive driving. You are responsible for the
vehicle's speed, braking in good time, and
steering correctly. Always adapt your driving
style to suit the prevailing road and weather conditions. Always pay attention to traffic
conditions and your surroundings. Otherwise,
you may fail to recognise dangers in time,
cause an accident and injure yourself and oth-
ers.
The radar sensor syste misautomatically
deactivated near radio telescope facilities
(Y page 433).
For Active Blind Spot Assis ttoassist you
when driving, the radar sensor syste mmust
be activated (Y page 283)and operational.
General notes
Active Blind Spot Assist use saradar sensor
system to monitor the area to the sides of
your vehicle which are behind the driver. A
warning display in the exterior mirrors draws
your attention to vehicles detected in the
monitored area. If you then switch on the cor-
responding turn signal to change lane, you
will also receive an optical and audible warn-
ing. If arisk of lateral collision is detected,
corrective brakin gmay help you avoid acol-
lision. To suppor tthe course- correcting brake
application ,Active Blind Spo tAssist uses the
forward-facin gradar senso rsystem. The free
space in the direction of travel is then evalu-
ated.
Active Blind Spot Assist supports you from a
speed of approximatel y30km/h.
Monitorin grange G
WARNING
Active Blin dSpot Assist monitors cer tain
areas in the immediate vicinit yofyour vehicle.
Vehicles that approach and driv epast at high
speeds are not detected. No visual nor audi-
ble warnings are emitted and the system does
not brake the vehicle to correc tyour course.
If the lanes are ver ywide, it may not be pos-
sible to monitor the complete width of the
neighbouring lane. For this reason, vehicles in
the next lane may not be detected, especially
if they are drivin ginastaggered formation.

kerbs, speed humps or similar elevations, try
to do so slowly and at an obtuse angle .Oth-
erwise ,the tyres, particularly the sidewalls,
ma ybed amaged. Regular checking of wheels and tyres
G
WARNING
Damaged tyres can cause tyre inflation pres-
sure loss .Asaresult,you coul dlose control
of your vehicle. There is arisk of accident.
Check the tyres regularly for signs of damage
and replace any damaged tyres immediately.
Regularly check the wheels and tyres of your
vehicle for damage at least once amonth, as
well as after drivin goff-road or on rough
roads .Damaged wheels can cause aloss of
tyr ep ressure. Pa yparticular attention to
damage such as:
R cuts in the tyres
R punctures
R tears in the tyres
R bulges on tyres
R deformation or severe corrosion on wheels
Regularly check the tyre tread depth and the
condition of the tread across the whole width
of the tyre (Y page 397). If necessary, turn
the front wheelst ofull lock in order to inspect
the inner side of the tyre surface.
All wheel smust have avalve cap to protect
the valve against dirt and moisture. Do not fit
anything onto the valve other than the stand-
ard valve cap or other valve caps approved by
Mercedes-Benz for your vehicle. Do not fit any
other valve caps or systems, e.g. tyre pres-
sure monitoring systems.
Regularly check the pressure of all the tyres,
particularly prior to long trips. Adjust the tyre
pressure as necessary (Y page 399).
Observe the notes on the emergenc yspare
wheel (Y page 414). The service life of tyres depends on various
factors, including the following:
R
driving style
R tyr ep ressure
R tyre mileage Tyre tread
G
WARNING
Insufficient tyre trea dwill reduce tyre trac-
tion. The tyre is no longer able to dissipate
water. This means that on wet road surfaces,
the risk of aquaplaning increases, in particular
where speed is not adapted to suit the driving
conditions. There is arisk of accident.
If the tyre pressure is too high or too low, tyres
may exhibit different levels of wear at differ-
ent locations on the tyre tread. Thus, you
should regularly check the tread depth and
the condition of the tread across the entire
width of all tyres.
Minimum tyre tread depth for:
R summer tyres: 3mm
R M+S tyres: 4mm
For safety reasons ,replace the tyres before
the legally prescribed limi tfor the minimum
tyr etrea ddepth is reached.. Selecting, fitting and replacing ty
res
R Only fi ttyres and wheels of the same type
and make.
R Only fit tyres of the correc tsize ont othe
wheels.
R Run in new tyres at moderate speeds for
the first 10 0km. They onl yreach their full
performanc eafter this distance.
R Do not drive wit htyres which have too little
tread depth .This otherwise significantly
reduce sthe traction on wet roads (aqua-
planing).
R Replace the tyres after six year satthe lat-
est, regardless of wear. Operation
