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.

on various factors. These include the
position and shape of the vehicles parked
in front and behind it and the conditions of
the location. It may be the case that Active
Parking Assist guides you too far into a
parking space, or not far enough into it. In
some cases, it may also lead you across or
ontothe curb. If necessary, you should
cancel the parking procedure with Active
Parking Assist.
RYou can also engage forward gear
prematurely. The vehicle redirects and
does not drive as far into the parking space.

ATTENTION ASSIST
Important safety notes
ATTENTION ASSIST is only an aid to the
driver. It might not always recognizefatigue
or increasing inattentiveness in time or fail to
recognizethem at all. The system is not a
substitute forawell-rested and attentive
driver.
General notes
ATTENTION ASSIST helps you during long,
monotonous journeys, such as on highways.
It is active in the range between 50 mph
(80 km/h) and 112 mph (180 km/h).
If ATTENTION ASSIST detects typical
indicators of fatigue or increasing lapses in
concentration on the part of the driver, it
suggests you takeabreak.
ATTENTION ASSIST assesses your level of
fatigue or lapses in concentration by taking
the following criteria into account:
Ryour personal driving style, e.g. steering
characteristics
Rjourney details, e.g. time of day and length
of journey
The functionality of ATTENTION ASSIST is
restricted and warnings may be delayed or
not occur at all:
Rif the road condition is poor, e.g. if the
surface is uneven or if there are potholes
Rif there isastrongside wind
Rif you have adoptedasporty driving style
with high cornering speeds or high rates of
acceleration
Rif you are predominantly driving slower
than 50 mph (80 km/h) or faster than
112 mph (180 km/h)

Checking the tire pressures
Important safety notes
Observe the notes on tire pressure
(Ypage 338).
Information on air pressure for the tires on
your vehicle can be found:
Ron the vehicle's Tire and Loading
Information placard on the B-pillar
(Ypage 345)
Ron the tire pressure label on the fuel filler
flap (Ypage 165)
Rin the "Tire pressure" section

Checking tire pressures manually
To determine and set the correct tire
pressure, proceed as follows:
XRemove the valve cap of the tire that is to
be checked.
XPress the tire pressure gauge securely onto
the valve.
XRead the tire pressure and compare it with
the recommended value on the Tire and
Loading Information placard (Ypage 338).
XIf the tire pressure is too low, increase it to
the recommended value.
XIf the tire pressure is too high, release air
by pressing down the metal pin in the valve.
Use the tip ofapen, for example. Then,
check the tire pressure again using the tire
pressure gauge.
XScrew the valve cap onto the valve.
XRepeatthese steps for the other tires.
Tire pressureloss warning system
(Canada only)
General notes
While the vehicle is in motion, the tire
pressure loss warning system monitors the
set tire pressure using the rotational speed of
the wheels. This enables the system to detect
significant pressure loss inatire. If the speed
of rotation ofawheel changes asaresult of
aloss of pressure,acorresponding warning
message will appearinthe multifunction
display.
You can recognizethe tire pressure loss
warning by theRun Flat Indicator
Active Press 'OK' to Restartmessage
which appears in theServ.menu of the
multifunction display. Further information on
the message displaycan be found under
"Restarting the tire pressure loss warning
system" section (Ypage 342).
Important safety notes
The tire pressure warning system does not
warn you of an incorrectly set tire pressure.
Observe the notes on the recommended tire
pressure (Ypage 338).
The tire pressure loss warning does not
replace the need to regularly check the tire
pressure. An even loss of pressure on several
tires at the same time cannot be detected by
the tire pressure loss warning system.
The tire pressure monitor is not able to warn
you ofasudden loss of pressure, e.g. if the
tire is penetrated byaforeign object.Inthe
event ofasudden loss of pressure, bring the
vehicle toahalt by braking carefully. Avoid
abrupt steering maneuvers.
The function of the tire pressure loss warning
system is limited or delayed if:
Rsnow chains are mounted on your vehicle's
tires.
Rroad conditionsare wintry.
Ryou are driving on sand or gravel.
