Load compensation
The vehicle can compensatedifferences in
thevehicle level by raisingorlowering the
rear axle. This is the case, for example, if
people get out or if luggage is being loaded.
Load compensation takes place if:
Radoor or the trunk lid/tailgate is opened
Rthe 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,for vehicle speed, for braking in good
time and for staying in your lane.
Ifadrive wheel spins due to insufficientgrip:
ROnly depress the accelerator pedalasfar
as necessary when pulling away.
RAccelerate less when driving.
!Never tow the vehiclewith one axle
raised. This may damage the transfer case.
Damageofthis sort is not covered by the
Mercedes-Benz Limited Warranty. All
wheels must remaineitheronthe ground
or be fully raised. Observe the instructions
for towing the vehicle with all wheels in full
contact with the ground.
iIn 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 allfour wheels are
permanently driven. Together with ESP®,it
improves the traction of yourvehicle
wheneveradrive wheel spins due to
insufficient grip.
PARKTRONIC
Important safetynotes
PARKTRONIC is an electronic parkingaid with
ultrasonic sensors. It indicates visually and
audibly the distancebetween your vehicle
and an object.
PARKTRONIC is only an aid. It is not a
replacementfor your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking
and exitingaparkingspace. When
maneuvering, parkingorpulling out of a
parkingspace, make sure that thereare 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 detectsuch objects
when they are in theimmediatevicinity of
thevehicle. You could damagethe vehicle
or the objects.
The sensors may not detect snow and other
objectsthat absorb ultrasonic waves.
Ultrasonic sources such as an automatic
car wash, the compressed-air brakes on a
truck orapneumatic drill could cause
PARKTRONIC to malfunction.
PARKTRONIC may not function correctly on
uneven terrain.
PARKTRONIC is activated automatically when
you:
Rswitch on the ignition
Rshift the transmission to positionD,RorN
Rrelease 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.

Tire pressuremonitor
General notes
Ifatire pressure monitor is installed, the
vehicle's wheels have sensors that monitor
the tire pressures in all four tires. The tire
pressure monitor warns you if the pressure
drops in one or more of the tires. The tire
pressure monitor only functions if the correct
sensors are installed on all wheels.
Information on tire pressures is displayed in
the multifunction display. Afterafew minutes
of driving, the current tire pressure of each
tire is shown in theServicemenu of the
multifunction display. For further information
on displaying this message, refer to the
"Checking the tire pressure electronically"
section (Ypage 344).

one or more tires has dropped suddenly
and the tires must be checked.
Observe the instructions and safety notes in
the display messages in the "Tires" section
(Ypage 258).
iIf the wheel positions on the vehicle are
rotated, the tire pressures may be
displayed for the wrong positions for a
short time. This is rectified afterafew
minutes of driving, and the tire pressures
are displayed for the correctpositions.
Restarting the tire pressuremonitor
When you restart the tire pressure monitor,
all existingwarning messages are deleted and
the warning lamps go out. The monitor uses
the currently set tire pressures as the
reference values for monitoring. In most
cases, the tire pressure monitor will
automatically detect the new reference
values after you have changed the tire
pressure. However, you can also define
reference values manually as described here.
The tire pressure monitor then monitors the
new tire pressure values.
XSet the tire pressure to the value
recommended for the corresponding
driving situation on the Tire and Loading
Information placard on the B-pillar on the
driver's side (Ypage 338).
Additional tire pressure values for different
loads can also be found on the tire pressure
table on the inside of the fuel filler flap
(Ypage 338).
XMake sure that the tire pressure is correct
on all four wheels.
XMake sure that the SmartKey is in position

Loading the vehicle
Instruction labels for tires and loads
GWARNING
Overloaded tires can overheat, causing a
blowout. Overloaded tires can also impair the
steering and driving characteristics and lead
to brake failure. There isarisk 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
of occupantsand the maximum
permissible vehicle load. It also contains

Example:
RTreadweargrade:200
RTractiongrade:AA
RTemperature grade:A
All passengercar tires must conform to the
statutory safety requirements in additionto
these grades.
iTheactual values for tires arevehicle-
specificand maydeviate from the values in
the illustration.
Treadwear
The treadweargrade isacomparative rating
based on the wearrate of thetirewhen tested
undercontrolled conditions onaspecified
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 performanceoftires 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
GWARNING
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 onawet surface as
measured under controlled conditions on
specified government test surfaces of asphalt
and concrete.Atire markedCmay have poor
traction performance.
The safe speed onawet, snowcovered or icy
road is always lower than on dry road
surfaces.
You should pay special attention to road
conditions when temperatures are around
freezingpoint.
Mercedes-Benzrecommendsaminimum
tread depthofin(4mm)onall four winter
tires. Observe the legally required minimum
tire tread depth (Ypage335). 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.
Further informationonwinter tires (M+S
tires) (Ypage336).
Temperature
GWARNING
The temperature grade for this tire is
established foratire 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 areA(the highest),
B, and C. Theserepresent the tire's
resistancetothe generationofheat and its
ability to dissipate heat when tested under
controlled conditions onaspecified indoor
laboratory test wheel. Sustained high
temperature can cause the material of the tire
to degenerateand reduce tire life, and
excessive temperature can lead to sudden
tire failure. The gradeCcorresponds toalevel
of performancewhich all passenger car tires
must meet under the Federal Motor Vehicle
Safety Standard No. 109. GradesBand A
represent higher levels of performanceonthe
laboratory test wheel than the minimum
required by law.

DOT, Tire Identification Number (TIN)
U.S. tire regulations prescribe that every tire
manufacturer or retreader must imprintaTIN
in or on the sidewall of every tire produced.
The TIN isauniqueidentification number. The
TIN enables the tire manufacturers or
retreaders to inform purchasers of recallsand
other safety-relevant matters. It makes it
possible for the purchaser to easily identify
the affected tires.
The TIN is made up of manufacturer
identification code,tire size$,tire type
code!and manufacturing date.
DOT (Department of Transportation):tire
