In the 0003or0002 position, the appropriate
wiping frequency is set automatically
according to the intensity of the rain. In
the 0002 position, the rain sensor is more
sensitive than in the 0003position, causing
the windshield wipers to wipe more
frequently.
If the wiper blades are worn, the windshield
will no longer be wiped properly. This could
prevent you from observing the traffic
conditions. Replace the wiper blades twice a

WARNING
DISTRONIC PLU Scanno talway sclearly
identify othe rroad users and complex traffic
situations.
In such cases, DISTRONIC PLUS may:
R give an unnecessary warning and then
brake the vehicle
R neither give awarning nor intervene
R accelerate unexpectedly
There is arisk of an accident.
Continue to drive carefully and be ready to
brake, in particular when warned to do so by
DISTRONIC PLUS. G
WARNING
DISTRONIC PLUS brakes your vehicle with up
to 40% of the maximum braking force. If this
braking force is insufficient ,DISTRONIC PLUS
warns you visually and audibly. There is arisk
of an accident.
In such cases, apply the brakes yourself and
try to take evasive action.
! If DISTRONIC PLUS or the HOLD function
is activated, the vehicle brakes
automatically in certain situations. To
prevent damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or other similar situations:
R when towing the vehicle
R in the car wash
If you fail to adapt your driving style,
DISTRONIC PLUS can neither reduce the risk
of accident nor override the laws of physics.
DISTRONIC PLUS cannot take into account
the road, traffic and weather conditions.
DISTRONIC PLUS is only an aid. You are
responsible for the distance to the vehicle in front,f
or vehicle speed, for braking in good
time and for staying in your lane.
Do not use DISTRONIC PLUS:
R in road and traffic conditions which do not
allow you to maintain aconstant speed e.g.
in heavy traffic or on winding roads
R on slippery road surfaces. Brakin gor
accelerating could cause the drive wheels
to lose traction and the vehicle could then
skid
R when there is poor visibility, e.g. due to fog,
heavy rain or snow
DISTRONIC PLUS may not detect narrow
vehicles driving in front,e .g. motorcycles, or
vehicles driving on adifferent line.
In particular, the detection of obstacles can
be impaired if:
R dirt on the sensors or anything else
coverin gthe sensors
R snow or heavy rain
R interference by other radar sources
R strongr adar reflections, for example, in
parking garages
If DISTRONIC PLUS no longer detect sa
vehicle in front,D ISTRONIC PLUS may
unexpectedly accelerate the vehicle to the
stored speed.
This speed may:
R be too high if you are driving in afilter lane
or an exit lane
R be so high in the right lane that you pass
vehicles driving on the left (left-han ddrive
countries)
R be so high in the left lane that you pass
vehicles driving on the right (right-hand
drive countries)
If there is achange of drivers, advise the new
driver of the speed stored.
General notes DISTRONIC PLUS regulates the speed and
automatically helps you maintain the
distance to the vehicle detected in front.
Vehicles are detected with the aid of the radar178
Driving systemsDriving and parking

sensor system. DISTRONIC PLUS brakes
automaticallysot hat the set speed is not
exceeded.
Change into alower gear in good time on long
and steep downhill gradients. This is
especially important if the vehicle is laden. By
doing so, you will make use of the braking
effect of the engine. This relieves the load on
the brake system and prevents the brakes
from overheating and wearing too quickly.
If DISTRONIC PLUS detects that there is arisk
of ac ollision, you will be warned visually and
acoustically.D ISTRONIC PLUS cannot
prevent acollision without your intervention.
An intermittent warning tone will then sound
and the distance warning lamp will light up in
the instrument cluster. Brake immediately in
order to increase the distance to the vehicle
in front or take evasive action provided it is
safe to do so.
For DISTRONIC PLUS to assist you, the radar
sensor system must be operational.
If there is no vehicle in front,D ISTRONIC
PLUS operates in the same way as cruise
control in the speed range between 20 mph
(Canada: 30 km/h) and 120 mph (Canada:
200 km/h). If avehicle is driving in front of
you, it operates in the speed range between
0m ph (0 km/h) and 120 mph (Canada:
200 km/h).
Do not use DISTRONIC PLUS while driving on
roads with steep gradients.
As DISTRONIC PLUS transmits radar waves,
it can resemble the radar detectors of the
responsible authorities. You can refer to the
relevant chapter in the Operator's Manual if
questions are asked aboutt his.

Load compensation
The vehicle can compensat
edifferences in
th ev ehicle level by raisin gorlowering the
rear axle. This is the case, for example, if
people get out or if luggage is being loaded.
Load compensation takes place if:
R ad oor or the trunk lid/tailgate is opened
R the parked vehicle is unlocked
For larger level changes, the engine must be
running. 4MATIC (permanent four-wheel drive)
If you fail to adapt your driving style, 4MATIC
can neither reduce the risk of accident nor
override the laws of physics. 4MATIC cannot
take account of road, weather and traffic
conditions. 4MATIC is only an aid. You are
responsible for the distance to the vehicle in
front,f or vehicle speed, for braking in good
time and for staying in your lane.
If ad rive wheel spins due to insufficien tgrip:
R Only depress the accelerator peda lasfar
as necessary when pulling away.
R Accelerate less when driving.
! Never tow the vehicl ewith one axle
raised. This may damage the transfer case.
Damag eofthis sort is not covered by the
Mercedes-Benz Limited Warranty. All
wheels must remai neithe ront he ground
or be fully raised. Observe the instructions
for towing the vehicle with all wheels in full
contact with the ground.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if
you use winter tires (M+S tires), with snow
chains if necessary.
4MATIC ensures that allf our wheels are
permanently driven. Together with ESP ®
,it
improves the traction of you rvehicle
whenever adrive wheel spins due to
insufficient grip. PARKTRONIC
Important safet ynotes PARKTRONIC is an electronic parkin
gaid with
ultrasonic sensors. It indicates visually and
audibly the distanc ebetween your vehicle
and an object.
PARKTRONIC is only an aid. It is not a

parkin gspace, make sure that ther eare no
persons, animals or objects in the area in
which you are maneuvering.
! When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer drawbars.
PARKTRONIC does not detec tsuch objects
when they are in th eimmediat evicinity of
th ev ehicle. You could damag ethe vehicle
or the objects.
The sensors may not detect snow and other
objectst hat absorb ultrasonic waves.
Ultrasonic sources such as an automatic
car wash, the compressed-air brakes on a
truck or apneumatic drill could cause
PARKTRONIC to malfunction.
PARKTRONIC may not function correctly on
uneven terrain.
PARKTRONIC is activated automatically when
you:
R switch on the ignition
R shift the transmission to position D,Ror N
R release the parking brake
PARKTRONIC is deactivated at speeds above
