WARNING
When the vehicle is being lowered, people
could become trapped if their limbs are
between the vehicle body and the wheels or
underneath the vehicle. There is a risk of
injury.
Make sure no one is underneath the vehicle or in the immediate vicinity of the wheel arches
when the vehicle is being lowered. G
WARNING
Vehicles with level control: The vehicle is slightly lowered if:
R you have selected comfort suspension tun-
ing and
R you lock the vehicle within approximately
60 seconds of switching off the engine
You and people in the vicinity of the wheel
arch or the underbody may thus become trap- ped. There is a risk of injury.
Make sure that nobody is in the vicinity of thewheel 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 then
R you lock the vehicle within approximately
60 seconds
When parking, position your vehicle so that it does not make contact with the curb 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.
Your vehicle regulates its height automati-
cally. All-round level control ensures the best possible suspension and constant ground
clearance, even with a laden 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: the vehicle is raised by approx-
imately 0.80 in (20 mm) when compared
with the normal level
R Lowered: the vehicle is raised by approx-
imately 0.40 in (10 mm) when compared
with the normal level
i These changes in level are so slight that
you are hardly aware of them.
The "Normal" and "Raised" vehicle levels can
be set manually. Driving systems
193Driving and parking Z
When changing from Comfort to Sport or
Sport +, the axle is lowered approximately
1.0 in (25 mm). When changing from Sport or Sport + to Comfort, the axle is raised approx-
imately 1.0 in (25 mm). This level change also
takes place when the vehicle is stationary.
If you drive faster than 105 mph (170 km/h), the rear axle level is set to a middle level. Thisincreases driving safety and reduces air
resistance. If you then drive slower than
93 mph (150 km/h), the level of the rear axle
is again adjusted to correspond to the selec-
ted suspension mode.
Load compensation
The vehicle can compensate differences in
the vehicle level by raising or lowering the
rear axle. This is the case, for example, if peo- ple get out or if luggage is being loaded.
Load compensation takes place if:
R a door, the trunk lid or the 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 con-
ditions. 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.
If a drive wheel spins due to insufficient grip:
R Only depress the accelerator pedal as far as
necessary when pulling away.
R Accelerate less when driving.
! Never tow the vehicle with one axle
raised. This may damage the transfer case.
Damage of this sort is not covered by the
Mercedes-Benz Limited Warranty. All
wheels must remain either on the 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 all four wheels are per-
manently driven. Together with ESP ®
, it
improves the traction of your vehicle when-
ever a drive wheel spins due to insufficient
grip. PARKTRONIC
Important safety notes PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It monitors the area
around your vehicle using six sensors in the
front bumper and six sensors in the rear
bumper. PARKTRONIC indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is only an aid. It is not a replace-
ment for your attention to your immediate
surroundings. You are always responsible for
safe maneuvering, parking and exiting a park-
ing space. When maneuvering, parking or
pulling out of a parking space, make sure that there are 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 detect such objects
when they are in the immediate vicinity of
the vehicle. You could damage the vehicle
or the objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic
car wash, the compressed-air brakes on a
truck or a pneumatic drill could cause
PARKTRONIC to malfunction. Driving systems
197Driving and parking Z
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.
Range of the sensors General notes
PARKTRONIC does not take objects into con-
sideration that are:
R below the detection range, e.g. people, ani-
mals or objects.
R above the detection range, e.g. overhang-
ing loads, truck overhangs or loading
ramps. :
Sensors in the front bumper, left-hand

General notes Active Parking Assist is an electronic parking
aid with ultrasound. It measures the road on
both sides of the vehicle. A parking symbol
indicates a suitable parking space. Active
steering intervention and brake application
can assist you during parking. You may also
use PARKTRONIC (Y page 197).
Important safety notes Active Parking Assist is merely an aid. It is not
a replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking
and exiting a parking space. Make sure that
no persons, animals or objects are in the
maneuvering range.
When PARKTRONIC is switched off, Active
Parking Assist is also unavailable. G
WARNING
While parking or pulling out of a parking
space, the vehicle swings out and can drive
onto areas of the oncoming lane. This could
result in a collision with another road user.
There is a risk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active Park- ing Assist parking procedure.
! If unavoidable, you should drive over
obstacles such as curbs slowly and not at a sharp angle. Otherwise, you may damage
the wheels or tires.
Active Parking Assist may possibly indicate
parking spaces which are not suitable for
parking, for example:
R where parking or stopping is prohibited
R in front of driveways or entrances and exits
R on unsuitable surfaces 200
Driving systemsDriving and parking
operational at speeds of up to approximately
22 mph (35 km/h). While in operation, the
system independently locates and measures
parking spaces on both sides of the vehicle.
Active Parking Assist will only detect parking spaces:
R parallel or at right angles to the direction of
travel
R that are parallel to the direction of travel
and at least 59 in (1.5 m) wide
R that are parallel to the direction of travel
and at least 39.5 in (1.0 m) longer than your vehicle
R that are at right angles to the direction of
travel and at least 39.5 in (1.0 m) wider
than your vehicle
i Note that Active Parking Assist cannot
measure the length of a parking space if it
is at right angles to the direction of travel.
You will need to judge whether your vehicle
will fit into the parking space.
When driving at speeds below 19 mph
(30 km/h), you will see the parking symbol as a status indicator in the instrument cluster.
When a parking space has been detected, anarrow towards the right or the left also
appears. By default, Active Parking Assist
only displays parking spaces on the front-
passenger side. Parking spaces on the driv-
er's side are displayed as soon as the turn
signal on the driver's side is activated. When
parking on the driver's side, this must remain
switched on until you acknowledge the use of
Active Parking Assist by pressing the a
button on the multifunction steering wheel.
The system automatically determines
whether the parking space is parallel or at
right angles to the direction of travel.
A parking space is displayed while you are
driving past it, and until you are approx-
imately 50 ft (15 m) away from it. Parking G
WARNING
If you leave the vehicle when it is only being
braked by Active Parking Assist it could roll
away if:
R there is a malfunction in the system or in
the voltage supply.
R the electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
R the battery is disconnected.
R the accelerator pedal has been depressed,
e.g. by a vehicle occupant.
There is a risk of an accident.
Before leaving the vehicle, always secure it
against rolling away.
i When PARKTRONIC detects obstacles,
Active Parking Assist brakes automatically
during the parking process. You are respon- sible for braking in good time.

Parking tips: R The way your vehicle is positioned in the
parking space after parking is dependent
on various factors. These include the posi-
tion 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
onto the curb. If necessary, you should can- cel the parking procedure with Active Park-
ing Assist.
R You can also select preselect transmission
position D. The vehicle redirects and does
not drive as far into the parking space.
Should a gear be changed too early, the
parking procedure will be canceled. A sen- sible parking position can no longer be ach-
ieved from this position.
Exiting a parking space In order that Active Parking Assist can sup-
port you when exiting the parking space:
R the border of the parking space must be
high enough at the front and the rear. A
curb is too small, for example.
R the border of the parking space must not be
too wide, as the position of the vehicle must
not exceed an angle of 45° to the starting
position as it is maneuvering into the park-
ing space.
R a maneuvering distance of at least 3.3 ft
(1.0 m) must be available.
i If PARKTRONIC detects obstacles, Active
Parking Assist brakes automatically whilst
the vehicle exits the parking space. You are
responsible for braking in good time.

General notes Example: CLS Coupe
Rear view camera :is an optical parking and
maneuvering aid. It shows the area behind
your vehicle with guidelines in the Audio 20 or
COMAND display.
The area behind the vehicle is displayed as a
mirror image, as in the rear view mirror.
i The text shown in the Audio 20 or
COMAND display depends on the language
setting. The following are examples of rear view camera messages in the COMAND
display.
Important safety notes The rear view camera is only an aid. It is not a
replacement for your attention to your imme- diate surroundings. You are always responsi-
ble for safe maneuvering and parking. When
maneuvering or parking, make sure that there are no persons, animals or objects in the area
in which you are maneuvering.
Under the following circumstances, the rear
view camera will not function, or will function
in a limited manner:
R if the trunk lid or tailgate is open
R in heavy rain, snow or fog R
at night or in very dark places
R if the camera is exposed to very bright light
R if the area is lit by fluorescent bulbs or LED
lighting (the display may flicker)
R if there is a sudden change in temperature,
e.g. when driving into a heated garage in
winter
R if the camera lens is dirty or obstructed.
Observe the notes on cleaning
(Y page 321)
R if the rear of your vehicle is damaged. In this
event, have the camera position and setting
checked at a qualified specialist workshop
The field of vision and other functions of the
rear view camera may be restricted due to
additional accessories on the rear of the vehi-
cle (e.g. license plate holder, bicycle rack).
On vehicles with height-adjustable chassis,
leaving the standard height can result in inac- curacies in the guide lines, depending on
technical conditions.
i The rear view camera is protected from
raindrops and dust by means of a flap.
When the rear view camera is activated,
this flap opens.
The flap closes again when:
R you have finished the maneuvering proc-
ess
R you switch off the engine
R you open the trunk
Observe the notes on cleaning
(Y page 321).
For technical reasons, the flap may remain
open briefly after the rear view camera has been deactivated.
