materials come into contact with parts of the
vehicle which are hot. Take particular care not
to park on dry grassland or harvested grain
fields. G

safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect.Y

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

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

vehicle using six sensors in the front bumper
and four sensors in the rear bumper. Driving systems
