Driving with DISTRONIC PLUS
Pulling away and driving
XIf you want to pull away with DISTRONIC
PLUS: remove your foot from the brake pedal.
XBriefly pull the cruise control lever towards
you?.
or
XAccelerate briefly.
Your vehicle pulls away and adapts its speed
to that of the vehicle in front. If no vehicle is
detected in front, your vehicle accelerates to the set speed.
The vehicle can also pull away when it is facing
an unidentified obstacle or is driving on a differ-
ent line from another vehicle. The vehicle then
brakes automatically.
If there is no vehicle in front, DISTRONIC PLUS
operates in the same way as cruise control.
If DISTRONIC PLUS detects that the vehicle in
front has slowed down, it brakes your vehicle. In
this way, the distance you have selected is main-
tained.
If DISTRONIC PLUS detects a faster-moving
vehicle in front, it increases the driving speed.
However, the vehicle is only accelerated up to
the speed you have stored.
Selecting the drive program
DISTRONIC Plus supports a sporty driving style
when you select the SportorSport Plus drive
program (
Ypage 147). Acceleration behind the
vehicle in front or to the set speed is then notice-
ably more dynamic. If you have selected the
Comfort drive program, the vehicle accelerates more gently. This setting is recommended in
stop-and-start traffic.
Changing lanes
If you change to the passing lane, DISTRONIC
PLUS supports you when:
Ryou are driving faster than 45 mph (70 km/h)
Ryou switch on the appropriate turn signal
RDISTRONIC PLUS does not detect a danger of
collision
If these conditions are fulfilled, your vehicle is
accelerated. Acceleration will be interrupted if
changing lanes takes too long or if the distance
between your vehicle and the vehicle in front
becomes too small.
iWhen you change lanes, DISTRONIC PLUS
monitors the left lane on left-hand-drive vehi-
cles or the right lane on right-hand-drive vehi-
cles.
Stopping
GWARNING
When leaving the vehicle, even if it is braked
only by DISTRONIC PLUS, it could roll away if:
Rthere is a malfunction in the system or in
the voltage supply.
RDISTRONIC PLUS has been deactivated
with the cruise control lever, e.g. by a vehi-
cle occupant or from outside the vehicle.
Rthe electrical system in the engine com-
partment, the battery or the fuses have
been tampered with.
Rthe battery is disconnected.
Rthe accelerator pedal has been depressed, e.g. by a vehicle occupant.
There is a risk of an accident.
If you wish to exit the vehicle, always turn off
DISTRONIC PLUS and secure the vehicle
against rolling away.
If DISTRONIC PLUS detects that the vehicle in
front is stopping, it brakes your vehicle until it is stationary.
Once your vehicle is stationary, it remains sta-
tionary and you do not need to depress the
brake.
After a time, the electric parking brake secures
the vehicle and relieves the service brake.

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 sur-
roundings. 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 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.
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.
PARKTRONIC is deactivated for the rear area
when you establish an electrical connection
between your vehicle and a trailer.
PARKTRONIC is activated automatically when
you:
Rswitch on the ignition
Rshift the transmission to position D,Ror N
Rrelease the electric parking brake
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). It is reactivated at lower
speeds.

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 ;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. 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
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 driv-
ing past it, and until you are approximately 50 ft
(15 m) away from it.

canceled when you depress the accelerator
pedal.
Active Parking Assist no longer supports you
with steering interventions and brake applica-
tions. When Active Parking Assist is finished,
you must steer and brake again yourself.
PARKTRONIC is still available.
Parking tips:
RThe 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,
you should cancel the parking procedure with
Active Parking Assist.
RYou 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 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:
Rthe border of the parking space must be high enough at the front and the rear. A curb is too
small, for example.
Rthe 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 parking
space.
Ra 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.
iIf PARKTRONIC detects obstacles, Active
Parking Assist brakes automatically whilst the
vehicle exits the parking space. You are

Active Lane Keeping Assist
General notes
Active Lane Keeping Assist monitors the area in
front of your vehicle by means of multifunction
camera :at the top of the windshield. Various
different areas to the front, rear and side of your
vehicle are also monitored with the aid of the
radar sensor system. Active Lane Keeping
Assist detects lane markings on the road and
can warn you before you leave your lane unin-
tentionally. If you do not react to the warning, a
lane-correcting application of the brakes can
bring the vehicle back into the original lane.
This function is available in a speed range
between 40 mph and 120 mph (60 km/h and
200 km/h).
For Active Lane Keeping Assist to assist you
when driving, the radar sensor system must be
operational.
Important safety notes
If you fail to adapt your driving style, Active Lane
Keeping Assist can neither reduce the risk of
accident nor override the laws of physics. Active
Lane Keeping Assist cannot take into account
road, weather or traffic conditions. Active Lane
Keeping Assist is only an aid. You are responsi-
ble for the distance to the vehicle in front, for
vehicle speed, for braking in good time and for
staying in your lane.
Active Lane Ke
eping Assist cannot continuously
keep your vehicle in its lane.
GWARNING
Active Lane Keeping Assist cannot always
clearly detect lane markings.

RThe bumpers of your vehicle are not suitable
for installing detachable trailer couplings.
RDo not install hired trailer couplings or other
detachable trailer couplings on the bumpers
of your vehicle.
RIf you no longer need the ball coupling,
remove it from the ball coupling recess. This
will reduce the risk of damage to the ball cou-
pling.
When towing a trailer, set the tire pressure on
the rear axle of the towing vehicle for the max-
imum load. You will find the values in the tire
pressure table in the fuel filler flap of the vehicle
(
Ypage 349).
Please note that when towing a trailer, the fol-
lowing driving systems have limited availability
or are not available at all:
RPARKTRONIC (Ypage 186)
RBlind Spot Assist (Ypage 203)
RActive Lane Keeping Assist (Ypage 209)
On vehicles without level control, the height of
the ball coupling will alter according to the load
placed on the vehicle. If necessary, use a trailer
with a height-adjustable drawbar.
You will find installing dimensions and loads
under "Technical data" (
Ypage 376).
Driving tips
Observe the information on ESP®trailer stabili-
zation (Ypage 67) and on pulling away with a
trailer (Ypage 138).
The maximum permissible speed for vehicle/
trailer combinations depends on the type of
trailer. Before beginning the journey, check the
trailer's documents to see what the maximum
permissible speed is. Observe the legally pre-
scribed maximum speed in the relevant country.
For certain Mercedes-Benz vehicles, the maxi-
mum permissible rear axle load is increased
when towing a trailer. See "Technical data" to
find out whether this applies to your vehicle
(
Ypage 376). If you utilize any of the added
maximum rear axle load when towing a trailer,
the vehicle/trailer combination may not exceed
a maximum speed of 60 mph (100 km/h) for
reasons concerning the operating permit. This
also applies in countries in which the permissi-
ble maximum speed for vehicle/trailer combi-
nations is above 60 mph (100 km/h). When towing a trailer, your vehicle's handling
characteristics will be different in comparison
with when driving without a trailer.
Use the left-hand steering wheel paddle shifter
to shift into a lower gear in good time on long
and steep downhill gradients.
This also applies if you have activated cruise
control or DISTRONIC PLUS.
This will use the braking effect of the engine, so
that less braking will be required to maintain the
speed. This relieves the load on the brake sys-
tem and prevents the brakes from overheating
and wearing too quickly. If you need additional
braking, depress the brake pedal repeatedly
rather than continuously.
Driving tips
If the trailer swings from side to side:
XDo not accelerate.
XDo not counter-steer.
XBrake if necessary.
RMaintain a greater distance from the vehicle
in front than when driving without a trailer.
RAvoid braking abruptly. If possible, brake gen-tly at first to allow the trailer to run on. Then,
increase the braking force rapidly.
RThe values given for gradient-climbing capa-
bilities from a standstill refer to sea level.
When driving in mountainous areas, note that
the power output of the engine and, conse-
quently, the vehicle's gradient-climbing capa-
bility, decreases with increasing altitude.
Installing the ball coupling
GWARNING
If the ball coupling is not correctly installed
and secured, it can come loose during the
journey and endanger other road users. There is a risk of an accident and injury.
Always install and secure the ball coupling as
described. Before every journey, ensure that
the ball coupling is secured with the bolt and
the corresponding spring cotter.
