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
replacemen tfor your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking
and exiting aparkin gspace. When
maneuvering, parkin gorpulling out of 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
11 mph (18 km/h). It is reactivated at lower
speeds.
PARKTRONIC monitors the area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper. Driving systems

When
aparking space has been detected, an
arrow towards the right or the left also
appears. By default, Active Parking Assist
only displays parking spaces on the front-
passenger side. Parking spaces on the
driver's side are displayed as soon as the turn
signal on the driver's side is activated. When
parking on the driver's side, this must remain
switched on until you acknowledge the use of
Active Parking Assist by pressing the 000C
button on the multifunction steering wheel.
i Take note that Active Parking Assist
cannot measure the size of parking spaces
that are at right angles to the direction of

supports you from aspeed of 60 km/h. If
miles is selected as the display unit, the
assistanc erange begins at 40 mph.
For Active Lane Keeping Assist to assist you
when driving, the radar sensor system must
be operational.
Important safet ynotes
If you fail to adapt your driving style, Active
Lane Keeping Assist can neither reduce the
risk of acciden tnor override the laws of
physics. Active Lane Keeping Assist cannot
take into account road, weather or traffic
conditions. It cannot detect possible road and
traffic conditions. Active Lane Keeping Assist
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. Active Lane Keeping Assist cannot
continuously keep your vehicle in its lane. G
WARNING
Active Lane Keeping Assist cannot always
clearly detect lane markings.
In such cases, Active Lane Keeping Assist
can:
R give an unnecessary warning and then
make acourse-correcting brake application
to the vehicle
R not give awarning or intervene
There is arisk of an accident.
Always pay particular attention to the traffic
situation and keep within the lane, especially
if Active Lane Keeping Assist alerts you.
Terminate the intervention in anon-critical
driving situation.
The system may be impaired or may not
function if:
R there is poor visibility, e.g. due to
insufficient illumination of the road, or due
to snow, rain, fog or spray
R there is glare, e.g. from oncoming traffic,
the sun or reflections (e.g. when the road
surface is wet)
R the windshield is dirty, fogged up, damaged
or covered, for instance by asticker, in the
vicinit yofthe camera
R the radar sensors in the front or rear
bumper or in the radiator grill are dirty, e.g.
due to snow
R there are no, several or unclear lane
markings for alane, e.g. in areas with road
construction work
R the lane markings are worn away,d ark or
covered up, e.g. by dirt or snow
R the distance to the vehicle in front is too
small and the lane markings thus cannot be
detected
R the lane markings change quickly, e.g.
lanes branch off, cross one another or

scraper. You could otherwise scratch or
damage the surfaces and protective film.
! Do not park the vehicle for an extended
period straight after cleanin git, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for afew minutes after
cleaning. Braking heats the brake discs and
the brake pads/linings, thus drying them.
The vehicle can then be parked. Regular care of your vehicle is
acondition for
