WARNING
Blind Spot Assist monitors certain area sinthe
immediate vicinity of yourv ehicle. Vehicles
that approach and drive past 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 complet ewidth of the
neighbourin glane. For this reason, vehicles in
the nextl ane may no tbedetected, especially
if they are driving in astaggered formation in
differen tlanes .This may be the case if vehi-
cles are driving at the edge of their lane that
is furthest away from your vehicle.
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 others. Blind Spot Assist monitors the area up to
3.0 mbehind your vehicle and directly nextto
your vehicle, as shown in th ediagram.
If th elanes are narrow ,vehicles drivin ginthe
lan ebeyond th elan en exttoy our vehicl emay
be indicated, especially if th evehicles are not
drivin ginthemiddle of their lane. This may
be th ecaseift here are vehicles at th eedge
of their lan enearest your vehicle. Due to th
enature of th esystem:
R warnings may be issued in error when driv-
ingc lose to crash barrier sorsimilar solid
lane borders.
R warnings may be interrupted when driving
alongside long vehicles, for example lor-
ries, for aprolonged time.
The two radar sensors for Blin dSpot Assist
are integrated int othe sides of the rear
bumper .Make sure that th ebumpe risfree of
dirt, ice or slush in the vicinity of the sensors.
The sensors must not be covered, for exam-
ple by cycle racks or overhanging loads. Fol-
lowing asevere impact or in the event of dam-
age to the bumpers, have the function of the
sensors checked at aqualified specialist
workshop. Blind Spot Assist may otherwise
not work properly.
Indicator and warning display G
WARNING
Blind Spot Assist is not active at speeds below
30 km/h. The indicator lamps in the exterior
mirrors are yellow. Vehicles in the monitoring
range are then not indicated.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognise dangers in time, cause an accident
and injure yourselfa nd others. :
Yellow indicator lamp/red warning lamp
If Blind Spo tAssist is switched on, indicator
lamp :in the exterior mirrors lights up yel-
low up to aspeed of 30 km/h. At speeds
above 30 km/h, the indicator lamp goes out

WARNING
Active Blind Spot Assist is only an aid and may
detec tvehicles/obstacles incorrectly or not
at all.
The system may be impaired or may not func-
tion if:
R there is poor visibility, e.g. due to snow,
rain, fog or spray.
R the rear and/or fron tsensor sare dirty.
Active Blind Spot Assist may not detect nar-
row vehicles, such as motorcycles or bicycles,
or only detect them too late. It cannot detect
vehicles which are overtaken at asmall dis-
tanc eand then enter the blind spot area.
Active Blind Spot Assist cannot detect road
and traffic conditions .Itisnotas ubstitute for
attentive driving. You are responsible for the
vehicle's speed, braking in good time, and
steering correctly. Always adapty our 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.
General notes
Active Blind Spot Assist uses aradar 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 braking may help you avoid acol-
lision. To support the course-correcting brake
application, Active Blind Spot Assist uses the
forward-facin gradar sensor system. The free
space in the direction of travel is then evalu-
ated.
Active Blind Spot Assist supports you from a
speed of approximately 30 km/h.
The radar sensor system is switched off auto-
matically in the vicinit yofradio telescope
facilities (Y page 368).
For Active Blind Spot Assist to assist you
when driving, the radar sensor system must
be activated (Y page 225) and operational.
Monitoring range G
WARNING
Active Blind Spot Assist monitors certain
areas in the immediate vicinit yofyour vehicle.
Vehicles that approach and drive past 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 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.
This may be the case if vehicles are driving at
the edge of their lane that is furthest away
from your vehicle.
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 others. Driving systems

other obstacles. If it is necessary to drive over
kerbs, speed humps or similar elevations, try
to do so slowly and at an obtuse angle. Oth-
erwise, the tyres, particularly the sidewalls,
may be damaged. Regular checking of wheels and tyres
G
WARNING
Damaged tyres can cause tyre inflation pres-
sure loss. As aresult, you could lose 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 driving off-road or on rough
roads. Damaged wheels can cause aloss of
tyre pressure. Pay particular 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 329). If necessary, turn
the front wheels to full lock in order to inspect
the inner side of the tyre surface.
All wheels must have avalve cap to protect
the valve against dirt and moisture. Do not fit
anything ontot he 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 331).
Observe the notes on the emergenc yspare
wheel (Y page 351). The service life of tyres depends on various
factors, including the following:
R
driving style
R tyre pressure
R tyre mileage Tyret

WARNING
Insufficient tyre tread will 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 limit for the minimum
tyre tread depth is reached.. Selecting, fitting and replacing tyres
R Only fit tyres and wheels of the same type
and make.
R Only fit tyres of the correc tsize ontot he
wheels.
R Run in new tyres at moderate speeds for
the first 100 km. They only reach their full
performanc eafter this distance.
R Do not drive with tyres which have too little
tread depth. This otherwise significantly
reduces the traction on wet roads (aqua-
planing).
R Replace the tyres after six years at the lat-
est, regardless of wear. Operation

ombinations General notes
! For safety reasons, Mercedes-Benz rec-
ommends that you only use tyres and
wheels which have been approved by
Mercedes-Benz specifically for your vehi-
cle. These are specially adapted to the control
systems, such as ABS or ESP
®
and are
marked as follows:
R MO =Mercedes-BenzO riginal
R MOE =Mercedes-Benz Original Extended
(tyres featuring run-flat characteristics)
R MO1 =Mercedes-BenzO riginal (only cer-
tain AMG tyres)
Mercedes-Benz Original Extended tyres
may only be usedonw heels that have been
specifically approved by Mercedes-Benz.
Only use tyres, wheels or accessories tes-
ted and approved by Mercedes-Benz. Cer-
tain characteristics, e.g. handling, vehicle
noise emissions or fuel consumption, may
otherwise be adversely affected. In addi-
tion, when driving with aload, tyre dimen-
sion variations could cause the tyres to
come into contact with the bodywork and
axle components.T his could result in dam-
age to the tyres or the vehicle.
Mercedes-Ben zaccepts no liability for
damag eresulting from the us eoftyres,
wheel soraccessorie sothe rthan those tes-
ted and approved.
Further information about wheels, tyres
and approved combinations can be
obtained from any qualified specialist
workshop.
! Retreaded tyres are neither tested nor
recommended by Mercedes-Benz, since
previous damage cannot always be detec-
ted on retreaded tyres. As aresult,
Mercedes-Ben zcannot guarante evehicle
safety if retreade dtyres are fitted. Do not
fit used tyres if you have no information
about their previous usage.
! Large wheels :the lower the section width
for acertain wheel size, the lower the ride
comfort is on poor road surfaces. Roll com-
fort and suspension comfort are reduced
and the risk of damage to the wheels and
tyres as aresult of driving over obstacles
increases. Wheel and tyrec
