4MATIC
! Never tow the vehicle with one axle raised.
This may damage the differential. 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 vehi-
cle with all wheels in full contact with the
ground.
4MATIC, together with ESP ®
, improves the trac-
tion of your vehicle whenever a drive wheel
spins due to insufficient grip.
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.
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. 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.
Suspension with Adaptive Damping
System
General notes A suspension with the Adaptive Damping Sys-
tem provides improved driving comfort and con-
tinuously controls the calibration of the damp-
ers. The damping characteristics adapt to the
current operating and driving situation.
The damping is tuned individually to each wheel
and depends on: R
your driving style, e.g. sporty R
the road surface conditions R
the drive program selected
The drive program can be set using the
DYNAMIC SELECT button ( Y
page 127).
Selecting Comfort mode In the Comfort drive program, the driving char-
acteristics of your vehicle are more comforta-
ble. Therefore, select this drive program if you
prefer a more comfortable driving style. Also
select the Comfort drive program when driving
fast on straight roads, e.g. on straight stretches
of highway. X
Press DYNAMIC SELECT button ( Y

Parking Assist PARKTRONIC
Important safety notes Parking Assist PARKTRONIC is an electronic
parking aid with ultrasound. It monitors the area
around your vehicle using six sensors in the
front bumper and six sensors in the rear
bumper. Parking Assist PARKTRONIC visually
and audibly indicates the distance between your
vehicle and an object.
Parking Assist PARKTRONIC is only 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. 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 maneuver-
ing.
! When parking, pay particular attention to
objects above or below the sensors, such as
flower pots or trailer drawbars. Parking Assist
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 of a truck or
a pneumatic drill could cause Parking Assist
PARKTRONIC to malfunction.
Parking Assist PARKTRONIC may not function
correctly on uneven terrain.
Parking Assist PARKTRONIC is activated auto-
matically when you: R
switch on the ignition R
shift the transmission to position D , R or NR
release the electric parking brake
Parking Assist PARKTRONIC is deactivated at
speeds above 11 mph (18 km/h). It is reactiva-
ted at lower speeds. Range of the sensors General notes Parking Assist PARKTRONIC does not take into
account obstacles located: R
below the detection range, e.g. people, ani-
mals or objects. R
above the detection range, e.g. overhanging
loads, tail sections or loading ramps of goods
vehicles.
C
Sensors in the front bumper, left-hand side
(example)
The sensors must be free from dirt, ice or slush.
They can otherwise not function correctly. Clean
the sensors regularly, taking care not to scratch
or damage them ( Y

Parking Pilot
General notes Parking Pilot is an electronic parking aid with
ultrasound. It measures the road on both sides
of the vehicle. A parking symbol indicates a suit-
able parking space. Active steering intervention
and brake application can assist you during
parking and when exiting a parking space. Park-
ing Assist PARKTRONIC is also available
( Y
page 160).
Important safety notes
Parking Pilot is only an aid. It is not a replace-
ment for your attention to your immediate sur-
roundings. 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 Parking Assist PARKTRONIC is deactiva-
ted, Parking Pilot 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 Parking Pilot
parking procedure.
! If unavoidable, you should drive over obsta-
cles such as curbs slowly and not at a sharp
angle. Otherwise, you may damage the
wheels or tires.162
Driving systems
Driving and parking

Parking Pilot may also display spaces not suita-
ble for parking, e.g.: R
where parking or stopping is prohibited R
in front of driveways or entrances and exits R
on unsuitable surfaces
Parking tips: R
On narrow roads, drive as close to the parking
space as possible. R
Parking spaces that are littered or overgrown
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 a parking
space being measured inaccurately. R
Pay attention to the warning messages of
Parking Pilot PARKTRONIC during the parking
procedure ( Y
page 161).R
You can intervene to correct the steering pro-
cedure at any time. Parking Pilot will then be
canceled. R
When transporting a load that protrudes from
your vehicle, you must not use Parking Pilot. R
Never use Parking Pilot when snow chains are
mounted. R
Make sure that the tire pressures are always
correct. This has a direct influence on the
parking characteristics of the vehicle.
Use Parking Pilot for parking spaces that are: R
that are parallel or at right-angles to the direc-
tion 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 detection range of
Parking Pilot will not be detected when the park-
ing space is measured. These are not taken into
account when the parking procedure is calcula-
ted, e.g. overhanging loads, truck overhangs or
loading ramps.
G WARNING
If there are objects above the detection range: R
Parking Pilot may steer in too early R
the vehicle may not stop in front of these
objects You may cause a collision as a result. There is
a risk of an accident.
If objects are located above the detection
range, stop and deactivate Parking Pilot.
For further information on the detection range
( Y
page 160).
Parking Pilot does not assist you parking in
spaces perpendicular to the direction of travel if: R
two parking spaces are located directly next
to one another R
the parking space is directly next to a low
obstacle such as a low curb R
you forward-park
Parking Pilot does not assist you parking in
spaces parallel or perpendicular to the direction
of travel if: R
the parking space is on a curb R
the system reads the parking space as being
blocked, for example by foliage or grass pav-
ing blocks R
the area is too small for the vehicle to maneu-
ver into R
the parking space is bordered by an obstacle,
e.g. a tree, a post or a trailer

that are parallel to the direction of travel and
at least 39.5 in (1.0 m) longer than your vehi-
cle 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 Parking Pilot 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 parking symbol D as a
status indicator in the instrument cluster. When
a parking space has been detected, an arrow
towards the right or the left also appears. Park-
ing Pilot only displays parking spaces on the
front-passenger side as standard. Parking
spaces on the driver'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 activated until you confirm the
use of Parking Pilot by pressing the v button
on the multifunction steering wheel. The system
automatically determines whether the parking
space is parallel or at right-angles to the direc-
tion of travel.
A parking space is displayed while you are driv-
ing past it, and until you are approximately 50 ft
(15 m) away from it.

G WARNING
If you leave the vehicle when it is only being
braked by Parking Pilot, 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 are tam-
pered with. R
the battery is disconnected. R
the vehicle is accelerated, e.g. by a vehicle
occupant.
There is a risk of an accident.
Before leaving the vehicle, always secure it
against rolling away.
i If Parking Assist PARKTRONIC detects
obstacles, Parking Pilot brakes automatically whilst the vehicle is parking. You are respon-
sible for braking in good time. X

Driving and parking

As soon as the parking procedure is complete,
the Parking Pilot Ended message appears in
the multifunction display and a warning tone
sounds. The vehicle is now parked.
The vehicle is kept stationary without the driver
having to depress the brake pedal. The braking
effect is canceled when you depress the accel-
erator pedal.
Parking Pilot no longer supports you with steer-
ing interventions and brake applications. When
Parking Pilot is ended, you must steer and brake
again yourself. Parking Assist PARKTRONIC is
still available.
Parking tips: R
The way your vehicle is positioned in the park-
ing space after parking is dependent on vari-
ous 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 Parking Pilot 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 abort the parking procedure with Park-
ing Pilot. R
You can also select preselect transmission
position D . The vehicle redirects and does not
drive as far into the parking space. Should the
transmission change take place too early, the
parking procedure will be canceled. A sensi-
ble parking posi tion can no longer be ach-
i
eved from this position.
Exiting a parking space In order for Parking Pilot to support you when
exiting the parking space: R
you need to have parked using Parking Pilot. R
the border of the parking space must be high
enough at the front and the rear. A curb stone
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 maneuvered into the parking
space. R
a maneuvering distance of at least 3.3 ft
(1.0 m) must be available .
Parkin g Pilo t can assist you with exiting a park-
ing space only if you have parked the vehicle
parallel to the direction of travel using Parking
Pilot. i If Parking Assist PARKTRONIC detects
obstacles, Parking Pilot brakes automatically
whilst the vehicle is exiting the parking space.
