Vehicle level Important safety notes

WARNING
People's limbs may become trapped if they
are located underneat hthe vehicle or
between the vehicle body and the tyres when the vehicle is lowering. There is adanger of
injury.
When lowering the vehicle, make sure no one
is underneat hthe vehicle or in the immediate
vicinit yofthe wheel arches. G
WARNING
Vehicles with level control:
The vehicle is slightly lowered if you:
R have selected comfor tsuspension tuning
and
R you lock the vehicle within approximately
60 seconds of switchin goff the engine
You and people in the vicinit yofthe wheel
arch or the underbody may thus become trap- ped. There is arisk of injury.
Make sure that nobody is in the vicinit yofthe
wheel arch or the underbody when you lock
the vehicle. !
The vehicle is lowered by about 15 mm if:
R you have selected "Comfort tuning"
R you switch off the engine and
R you lock the vehicle within approximately
60 seconds
When parking, position your vehicle so that it does not make contact with the kerb as
the vehicle is lowered. Your vehicle could
otherwise be damaged.
If you unlock the vehicle within 60 seconds of
having switched the engine off, the vehicle is
lowered slightly when Comfort suspension
mode is selected.
Observe the notes on driving with atrailer
(Y page 267).
Your vehicle regulates its height automati-
cally. All-roun dlevel control ensures the best
possible suspension and constant ground
clearance, even with aladen vehicle. When
you drive fast, the vehicle is lowered auto-
matically to improve driving safety and to
reduce fuel consumption.
The following vehicle levels are possible:
R Normal
R Raised (vehicles without 4MATIC): the vehi-
cle is raised by approximately 25 mm when compared with the normal level
R Raised (vehicles with 4MATIC): the vehicle
is raised by approximately 35 mm when
compared with the normal level
R Lowered: the vehicle is lowered by approx-
imately 10 mm when compared with the
normal level
The "Normal" and "Raised" vehicle levels can be set manually.
The "Lowered" vehicle level is set automati-
cally:
R at speeds above 140 km/h
R if you have selected "Sport mode"

25 mm
.The leve lchange also occurs when
stationary.
If you drive faster than 170 km/h, the rear
axle leve lisset to amiddle level. Thi sincrea-
ses road safety and reduces airr esistance. If
you then drive slower than 150 km/h, the
leve loft he rear axle is again adjusted to cor-
respond to the selected suspension mode.
Load compensation
The vehicle can compensate differences in
the vehicle leve lbyraising or lowering the
rear axle .Thisist he case ,for example, when
people get out of the vehicle or whe nlug gage
is removed.
Al oadc ompensation occurs if:
R ad oor, the boot lid or the tailgate is opened
R the parked vehicle is unlocked
The engine needs to be running for larger level
changes. 4MATIC (permanent all-whee
ldrive)
If you fai ltoadapt you rdriving style, 4MATIC
can neither reduce the risk of an accident nor override the laws of physics. 4MATIC cannot
take account of road ,weather and traffic con-
ditions. 4MATIC is only an aid. You are
responsibl efor the distance to the vehicle in
front, for vehicle speed, for braking in good
time, and for staying in lane.
If ad rive wheel spins due to insufficient grip:
R whe npulling away,o nly depress the accel-
erato rpedal as far as is necessary.
R accelerate les swhend riving.
! Never tow the vehicle with one axle
raised. Thi smay damage the transfer case.
Damag eofthis sort is not covered by the
Mercedes-Benz implied warranty. All
wheels must remain eithe ronthe ground or
be fully raised. Observe the instructions for towing the vehicle with allw heels in full
contact with the ground.
i In wintry driving conditions, the maximum
effect of 4MATIC can only be achieved if you use winter tyres
(M+S tyres), with snow
chains if necessary.
4MATIC ensures that allf our wheels are per-
manently driven. Together with ESP ®
,it
improves the traction of you rvehicle when-
ever adrive wheel spins due to insufficient
grip. PARKTRONIC
Important safety notes PARKTRONI
Cisanelectronic parking aidw ith

PARKTRONI Cisonly an aid. It is not asubsti-
tute for you rattention to the immediate sur-

PARKTRONI Cdoes not detect such objects

Parking tips:
R on narrow roads, drive as closely as possi-
ble past the parking space.
R parking spaces that are littered or over-
grown might be identified or measured
incorrectly.
R parking spaces that are partially occupied
by trailer drawbars might not be identified
as such or be measured incorrectly.
R snowfall or heavy rain may lead to aparking
space being measured inaccurately.
R pay attention to the PARKTRONIC
(Y page 237) warning messages during the
parking procedure.
R you can intervene in the steerin gprocedure
to correc titatany time. Active Parking
Assist will then be cancelled.
R when transportin gaload which protrudes
from your vehicle, you should not use
Active Parking Assist.
R never use Active Parking Assist when snow
chains are fitted.
R make sure that the tyre pressures are
alway scorrect. This has adirect influence
on the parking characteristics of the vehi-
cle.
Use Active Parking Assist for parking spaces
that are:
R parallel or at right angles to the direction of
travel
R on straight roads, not bends
R on the same level as the road, e.g. not on
the pavement
Detecting parking spaces Objects located above the height range of
Active Parking Assist will not be detected
when the parking space is measured. These
are not taken into account when the parking
procedure is calculated, e.g. overhanging
loads, tail sections or loading ramps of goods
vehicles. G
WARNING
If there are object sabove the detection range:
R Active Park Assist may steer too early
R the vehicle may not stop in fron tofthese
objects.
This could cause acollision. There is arisk of
an accident.
If object sare located above the detection
range, stop and switch off Active Parking
Assist.
For further information on the detection
range (Y page 236).
Active Parking Assist does not assist you
parking in spaces at right angles to the direc-
tion of travel if:
R two parking spaces are located directly
next to one another
R the parking space is directly next to alow
obstacle such as alow kerb
R you forward park
Active Parking Assist does not assist you
parking in spaces that are parallel or at right
angles to the direction of travel if:
R the parking space is on akerb
R the system reads the parking space as
being blocked, for example by foliage or
grass paving blocks
R the area is too small for the vehicle to
manoeuvre into
R the parking space is bordered by an obsta-
cle, e.g. atree, apost or atrailer Example: detected parking space

can take over the steering before the vehicle has exited the parking space completely. This
is useful,f or example when you recognise
that it is already possibletop ull out of the

Towing atrailer For vehicles with
atrailer tow hitch, the min-
imum length for parking spaces is slightly
increased.
If you have attached atrailer to your vehicle,
you should not use Active Parking Assist.
Once the electrical connection is established between your vehicle and the trailer, Active
Parking Assist is no longer available.
