R you actively change lane
R you switch on the turn signal
R you take your hands off the steering wheel or
do not steer for a prolonged period of time
i Once you have finished changing lanes,
Active Steering Assist automatically reacti-
vates.
Active Steering Assist cannot provide assis-
tance:
R on very sharp corners
R when towing a trailer
R when a loss of tire pressure or a defective tire
has been detected and displayed
Observe the important safety notes on Active
Distance Assist DISTRONIC (Y page 158).
The steering interventions are carried out with a limited steering moment. The system requires
the driver to keep his hands on the steering
wheel and to steer himself.
If you do not steer yourself or if you take your
hands off the steering wheel for a prolonged
period of time, the system will first alert you with
a visual warning. A steering wheel symbol
appears in the multifunction display. If you have
still not started to steer and have not taken hold of the steering wheel after five seconds at the
latest, a warning tone also sounds to remind you
to take control of the vehicle. Active Steering
Assist is then switched to passive. Active Dis-
tance Assist DISTRONIC remains active.

General notes The HOLD function can assist the driver in the
following situations:
R when pulling away, especially on steep slopes
R when maneuvering on steep slopes
R when waiting in traffic
The vehicle is kept stationary without the driver
having to depress the brake pedal.
The braking effect is canceled and the HOLD
function deactivated when you depress the
accelerator pedal to pull away.
i Do not use the HOLD function when driving
off-road, on steep uphill or downhill gradients or on slippery or loose surfaces. The HOLD
function cannot hold the vehicle on such sur- faces. Driving systems
165Driving and parking Z

The electric parking brake secures the vehicle
automatically if the HOLD function is activated
when the vehicle is stationary and:
R a system malfunction occurs
R the power supply is insufficient
On steep uphill or downhill gradients or if there
is a malfunction, the transmission may also be
automatically shifted to position 005D.4MATIC
4MATIC ensures that all four wheels are perma-
nently driven. Together with ESP ®
and 4ETS, it
improves the traction 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.
! 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 vehi-
cle with all wheels in full contact with the
ground.
! A function or performance test should only
be carried out on a two-axle dynamometer.
Before you operate the vehicle on such a
dynamometer, please consult a qualified
workshop. You could otherwise damage the
drive train or the brake system.
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. DSR (Downhill Speed Regulation)
General notes DSR is an aid to assist you when driving down-
hill. It keeps the speed of travel at the speed
selected on the on-board computer. The steeper
the downhill gradient, the greater the DSR brak- ing effect on the vehicle. When driving on flat
stretches of road or on an uphill gradient, the
DSR braking effect is minimal or nonexistent.
DSR controls the vehicle’s speed when it is acti-
vated and the transmission is in position 005B,005E
or 005C. You can drive at a higher or a lower speed
than that set on the on-board computer at any
time by accelerating or braking.
Important safety notes G
WARNING
If the speed driven and the set speed deviate and you activate DSR on a slippery road sur-
face, the wheels may lose traction. There is an
increased danger of skidding and accidents.
Before switching DSR on, please take into
consideration the road surface and the differ- ence between driving speed and the set
speed.
If you fail to adapt your driving style, DSR can
neither reduce the risk of accident nor override the laws of physics. DSR cannot take account of
road, weather and traffic conditions. DSR is only
an aid. You are responsible for the distance to
the vehicle in front, for vehicle speed, for brak-
ing in good time and for staying in your lane.
You are always responsible for keeping control
of the vehicle and for assessing whether the
downhill gradient can be managed. DSR may not always be able to keep to the set speed, depend-
ing on road surface and tire conditions. Select a
set speed suitable for the prevailing conditions
and when necessary, apply the brakes manually.

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. Make sure that there
are no persons, animals or objects in the maneu- vering area while maneuvering and parking in/
leaving parking spaces.
! 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.
PARKTRONIC may not function correctly on
uneven terrain.
! Fold in the ball coupling if the trailer tow
hitch is not required. PARKTRONIC measures
the minimum detection range to an obstacle
from the bumper, not the ball coupling.
Parking Assist PARKTRONIC is deactivated for
the rear area when you establish an electrical
connection between your vehicle and a trailer. Parking Assist PARKTRONIC is activated auto-
matically when you:
R switch on the ignition
R shift the transmission to position 005B,005Eor
005C
R 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, such as persons,
animals or objects
R above the detection range, such as overhang-
ing loads, truck overhangs or loading ramps 0043
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 page 305). Driving systems

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 inter-
vention and brake application can assist you
during parking. Parking Assist PARKTRONIC is
also available (Y page 173).
Important safety notes Active Parking Assist is merely an aid. It is not a
replacement for your attention to your immedi-
ate surroundings. You are always responsible
for safe maneuvering, parking and exiting a
parking space. Make sure that no persons, ani-
mals or objects are in the path of your vehicle.
When Parking Assist PARKTRONIC is deactiva-
ted, 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
cause you to collide with other road users or
objects. There is a risk of an accident.
Pay attention to other road users or objects.
Stop the vehicle if necessary or cancel the
Active Parking Assist parking procedure.
! If they cannot be avoided, drive over obsta-
cles such as curbs slowly and at an obtuse
angle. Otherwise, you may damage the
wheels or tires.
Active Parking Assist may also show parking
spaces that are not suitable for parking, e.g.: R where parking or stopping is prohibited
R in front of driveways or entrances and exits
R on unsuitable surfaces 176
Driving systemsDriving and parking

R
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 Active Parking Assist cannot
measure the size 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 0044as a
status indicator in the instrument cluster. When
a parking space has been detected, an arrow
towards the right or the left also appears. By
default, Active Parking Assist only displays park- ing spaces on the front-passenger side. 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 Active Parking Assist by pressing the
0076 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 driv- ing past it, and until you are approximately 50 ft
(15 m) away from it.
Parking G
WARNING
If you leave the driver's seat when the vehicle is being braked only by the Active Parking
Assist, it could roll away in the following sit-
uations:
R if there is a malfunction in the system or in
the voltage supply
R if the electrical system in the engine com-
partment, the battery or the fuses have
been tampered with
R if the battery is disconnected
R if the vehicle is accelerated, e.g. by a vehi-
cle 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, Active Parking Assist will brake
automatically whilst the vehicle is parking.
You are responsible for braking in good time.

tions. When Active Parking Assist is finished,
you must steer and brake again yourself. Park-
ing 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 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,
cancel the parking procedure with Active
Parking Assist.
R You can also preselect transmission position
005B. 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 position can no longer be ach-
ieved from this position.
Exiting a parking space In order that Active Parking Assist can support
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. Your vehicle can be maneuvered
into a position at a maximum of 45° to the
starting position in the parking space.
R a maneuvering distance of at least 3.3 ft
(1.0 m) must be available.
Active Parking Assist can only assist you with
exiting a parking space if you have parked the
vehicle parallel to the direction of travel using
Active Parking Assist.
i If Parking Assist PARKTRONIC detects
obstacles, Active Parking Assist brakes auto-
matically whilst the vehicle is exiting the park- ing space. You are responsible for braking in
good time.
