Driving systemsDriving and parking

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 yourv ehicle.In
this way,t he distance you have selected is main-
tained.
If DISTRONIC PLUS detects afaster-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 asporty driving style
when you have selected the Sor S+ drive pro-
gram (Y page 161). Acceleration behind the
vehicle in front or to the set speed is then notice- ablym ore dynamic. If you have selected the Cor
E drive program, the vehicle accelerates more
gently. This setting is recommended in stop-
start traffic.
Changing lanes
If you change to the overtaking lane, DISTRONIC
PLUS supports you if:
R you are driving faster than 70 km/h
R you switch on the respective turn signal
R DISTRONIC PLUS does not detect adanger of
collision
If these conditions are met, yourv ehicle is accel-
erated. Acceleration willbei nterrupted if chang-
ing lanes takes too long or if the distance
betwee nyourv ehicle and the vehicle in front
becomes too small.
i Vehicles with COMAND Online:
when you
change lanes, DISTRONIC PLUS monitors the right lane in the case of left-side traffic or the
left lane in the case of right-side traffic.
Vehicles with Audio 20: when you change
lanes, DISTRONIC PLUS monitors the left lane
on left-hand-drive vehicle sorthe right lane on
right-hand-drive vehicles. Road and traffic conditions i
The following function is only available in
vehicle swith the Driving Assistance Plus
package.
The function is not operational in all coun-
tries.
DISTRONIC PLUS uses additional information
from yourn avigation system so that it can adapt
to certain traffic situations. This is the case if,
whilef ollowing avehicle,D ISTRONIC PLUS is
active and you:
R approach or drive around aroundabout
R approach aT-junction
R turn off at amotorway exit
R approach atollgate
Even if the vehicle in front leaves the detection
range, DISTRONIC PLUS temporaril ymaintains
the current driving speed and does not acceler- ate. This is basedont he current map data in the
navigation system.
Afterwards, the vehicle accelerates back to the
speed you set.
The system takes into account the fact that
overtaking on the right is not permitted on
motorway sorhigh-speed major roads at speeds
above 80 km/h. The driving speed is adjusted to the speed of the queueofv ehiclesinthe adja-
cent lane to the left.
i Prevention of overtaking on the right applies
to countries where traffic drives on the right.
In countries where traffic drives on the left,
overtaking on the left is prevented accord-
ingly. Driving systems

Tip sfor driving with DISTRONIC PLUS General notes
Pay particular attention in the followin gtraffic
situations:
R Cornering, enterin gand exiting abend: the
ability of DISTRONIC PLUS to detec tvehicles
when cornering is limited. Your vehicle may
brak eunexpectedly or late.
R Driving on adifferen tline: DISTRONIC PLUS
may not detec tvehicles which are not driving
in the middle of their lane. The distance to the
vehicle in fron twill be too short.
R Other vehicles changing lane: DISTRONIC
PLUS has not detected the vehicle cuttin gin
yet. The distance to this vehicle will be too
short.
R Narro wvehicles: DISTRONIC PLUS has not
yet detected the vehicle in fron tonthe edge
of the carriageway because of its narrow
width. The distance to the vehicle in fron twill
be too short.
R Obstacles and stationar yvehicles:
DISTRONIC PLUS does not brak efor obsta-
cles or stationar yvehicles. If, for example, the
detected vehicle turn sacorner and reveals an
obstacle or stationar yvehicle, DISTRONIC
PLUS will not brak efor these.
R Crossin gvehicles: DISTRONIC PLUS may mis-
takenly detec tvehicles that are crossin gyour
lane. Activatin gDISTRONIC PLUS at traffic
light swith crossin gtraffic ,for example, could
cause your vehicle to pull away unintention-
ally.
In such situations ,brak eifn ecessary.

X Switch the ignition back on. The problem may be caused by an external source of radio or ultra-
sound waves.
X See if PARKTRONIC functions in adifferent location. Active Parking Assist
General notes Active Parking Assist is an electronic parking aid
with ultrasound. It measures the road on both
sides of the vehicle. Aparking symbol indicates
as uitable parking space. Active steering inter-
vention and brake application can assist you
during parking and when exiting aparking
space. You may also use PARKTRONIC
(Y page 197).
Important safety notes Active Parking Assist is only an aid. It is not a
substitute for your attention to the immediate
surroundings. The responsibility for safe
manoeuvring and parking remains with you.
Make sure that no persons, animals or objects
are in the manoeuvring range.
When PARKTRONIC is deactivated, Active Park-
ing Assist is also unavailable.
For vehicles with the trailer tow hitch folded out,
the minimum length for parking spaces is
slightly longer.
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. PARKTRONIC is
deactivated for the rear area. G
WARNING
While parking or pulling out of aparking
space, the vehicle swings out and can drive
onto areas of the oncomingl ane. This could
cause you to collide with other road users.
There is arisk 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 obsta-
cles such as kerbs slowly and not at asharp
angle. Otherwise, you may damage the
wheels or tyres.
Active Parking Assist may also display spaces
not suitable for parking, e.g.: R parking or stopping restrictions
R in front of driveways or entrances and exits
R unsuitable surfaces Driving systems
201Driving and parking Z

Parking tips:
R on narrow roads, drive as closely as possible
past the parking space
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 aparking
space being measured inaccurately
R pay attention to the PARKTRONIC
(Y page 199) warning messages during the
parking procedure
R you can intervene in the steerin gprocedure to
correc titata ny 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 always
correct. This has adirect influenc eonthe
parking characteristics of the vehicle.
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 Object
slocated 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 cal- culated, e.g. overhangin gloads, 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 frontoft hese
objects
This could cause acollision. There is arisk of
an accident. If object
sare located above the detection
range, stop and deactivate Active Parking
Assist.
For further information on the detection range
(Y page 198).
Active Parking Assist does not assist you park-
ing in spaces at right angles 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 alow
obstacle such as alow kerb
R you forward park
Active Parking Assist does not assist you park-
ing 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 pav-
ing blocks
R the area is too small for the vehicle to
manoeuvre into
R the parking space is bordered by an obstacle,
e.g. atree, apost or atrailer :
