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

WARNING
Overloaded tires can overheat, causing a
blowout. Overloaded tires can also impair the
steering and driving characteristics and lead
to brake failure. There is arisk of accident.
Observe the load rating of the tires. The load
rating must be at least half of the GAWR of
your vehicle. Never overload the tires by
exceeding the maximum load.
Two instruction labels on your vehicle show
the maximum possible load.
(1) The Tire and Loading Information placard is on the B-pillar on the driver's side. The
Tire and Loading Information placard
shows the maximum permissible number

Treadwear The treadwea
rgrade is acomparative rating
based on the wearr ate of thetirew hen tested
unde rcontrolled conditions on aspecified
U.S. government course. For example, atire
graded 150 would wear one and one-half
times as well on the government course as a
tire graded 100.
The relative performanc eoftires depends
upon the actual conditions of their use,
however, and may depart significantly from
the norm, due to variations in driving habits,
service practices and differences in road
characteristics and climate conditions.
Traction G
WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
! Avoid wheelspin. This can lead to damage
to the drive train.
The traction grades, from highest to lowest,
are AA, A, B, and C. Those grades represent
the tire's ability to stop on awet surface as
measured under controlled conditions on
specified government test surfaces of asphalt
and concrete. Atire marked Cmay have poor
traction performance. The safe speed on
awet, sno wcovered or icy
road is always lower than on dry road
surfaces.
You should pay special attention to road
conditions when temperatures are around
freezin gpoint.
Mercedes-Ben zrecommends aminimum
tread dept hof001Fin(4 mm )ona ll four winter
tires. Observe the legally required minimum
tire tread depth (Y page335). Winter tires can
reduce the braking distance on snow-covered
surfaces in comparison with summer tires.
The braking distance is still much further than
on surfaces that are not icy or covered with
snow. Take appropriate care when driving.

tires) (Y page336).
Temperature G
WARNING
The temperature grade for this tire is
established for atire that is properly inflated
and not overloaded. Excessive speed,
underinflation, or excessive loading, either
separately or in combination, can cause
excessive heat build-up and possible tire
failure.
The temperature grades are A(the highest),
B, and C. Thes erepresent the tire's

temperature can cause the material of the tire
to degenerat eand reduce tire life, and
excessive temperature can lead to sudden
tire failure. The grade Ccorresponds to alevel
of performanc ewhich all passenger car tires
must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades Band A
represent higher levels of performanc eonthe
