Deactivating DISTRONIC PLUS G
WARNING
DISTRONIC PLUS is deactivated and releases
the brakes if the vehicle is slowed down to a
speed below 20 mph (30km/h) by the system,
provided that DISTRONIC PLUS does not
detec tavehicle directly in front. At this point,
the driver must apply the brakes in order to
slow down further and bring the vehicle to a
standstill. Cruise control lever
There are several ways to deactivate
DISTRONIC PLUS:
X
Briefly press the cruise control lever
forwards 0002.
or
X Brake, unless the vehicle is stationary.
When you deactivate DISTRONIC PLUS, you

in the multifunction display for approximately
five seconds. i
The lasts peed stored remains stored until
you switch off the engine.
i DISTRONIC PLUS is not deactivated if you
depress the accelerator pedal. If you
accelerate to overtake, DISTRONIC PLUS
adjusts the vehicle's speed to the last
speed stored after you have finished
overtaking.
DISTRONIC PLUS is automatically
deactivated if:
R you engage the electric parking brake or if
the vehicle is automatically secured with
the electric parking brake.
R you are driving slower than 15 mph
(25 km/h) and there is no vehicle in front,
or if the vehicle in front is no longer
detected.

Tips for driving with DISTRONIC PLUS Important safety notes
G
WARNING
The DISTRONIC PLUS works to maintain the
speed selected by the driver unless a moving
obstacle proceeding directly ahead of it in the
same travel direction is detected (e.g.
following another vehicle ahead of you at your
set distance). Driving systems
193Driving and parking
Z

This means that:
R
Your vehicle can pass another vehicle after
you have changed lanes.
R While in a sharp turn or if the preceding
vehicle is in a sharp turn, the DISTRONIC
PLUS could lose sight of the preceding
vehicle. Your vehicle could then accelerate
to the previously selected speed.
The DISTRONIC PLUS regulates only the
distance between your vehicle and those
directly ahead of it. It may not register
stationary objects in the road, e.g.:
R a stopped vehicle in a traffic jam
R a disabled vehicle
R an oncoming vehicle
The driver must always be alert, observe all
traffic and intercede as required by means of
steering or braking the vehicle. G
WARNING
The DISTRONIC PLUS should not be used in
snowy or icy road conditions.
The following contains descriptions of certain
road and traffic conditions in which you must
be particularly attentive. In such situations,
brake if necessary. DISTRONIC PLUS is then
deactivated.
Cornering, going into and coming out of a
bend The ability of DISTRONIC PLUS to detect
vehicles when cornering is limited. Your
vehicle may brake unexpectedly or late. Vehicles traveling on
adifferent line DISTRONIC PLUS may not detect vehicles
traveling on a different line. The distance to
the vehicle in fron
twill be too short.
Other vehicles changing lanes DISTRONIC PLUS has not detected the
vehicle cutting in yet. The distance to this
vehicle will be too short.
Narrow vehicles
DISTRONIC PLUS has not yet detected the
vehicle in front on the edge of the road,194
Driving systemsDriving and parking

because of its narrow width. The distance to
the vehicle in fron
twill be too short.
Obstructions and stationary vehicles DISTRONIC PLUS does not brake for
obstacles or stationary vehicles. If, for
example, the detected vehicle turns a corner
and reveals an obstacle or stationary vehicle,
DISTRONIC PLUS will not brake for these.
Crossing vehicles DISTRONIC PLUS may mistakenly detect
vehicles that are crossing your lane.
Activating DISTRONIC PLUS at traffic lights
with crossing traffic, for example, could cause
your vehicle to pull away unintentionally. HOLD function

PARKTRONIC
Important safety notes PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It indicates visually and
audibly the distance between your vehicle
and an object.
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 objectsint he 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.
PARKTRONIC is activated automatically when
you:
R switch on the ignition.
R shift the transmission to position D,Ror
N.
R release the electric parking brake.
PARKTRONIC is deactivated at speeds above
11 mph (18km/h). It is reactivated at lower
speeds.
PARKTRONIC monitors the area around your
vehicle using six sensors in the front bumper
and four sensors in the rear bumper. Range of the sensors General notes
PARKTRONIC does not take objects into
consideration that are:
R
below the detection range, e.g. people,
animals or objects
R above the detection range, e.g.
overhanging loads, truck overhangs or
loading ramps. 0002

R
Snowfall or heavy rai nmay lead to a parking
space being measured inaccurately.
R Pay attentio nto the PARKTRONIC
(Y page 204) warning messages during the
parking procedure.
R You can intervene in the steering procedure
to correct it at any time. Active Parking
Assist will then be canceled.
R When transporting a load which protrudes
from your vehicle, you should not use
Active Parking Assist.
R Never use Active Parking Assist when snow
chains are installed.
R Make sure that the tire pressures are
always correct. This has adirec tinfluence
on the parking characteristics of the
vehicle.
General notes Active Parking Assist is an electronic parking
aid with ultrasound. Ultrasound is used to
measure the road on both sides of the vehicle.
As uitable parking space is indicated by the
parking symbol. Active steering intervention
can assis tyou during parking.
You may also use PARKTRONIC
(Y page 203). When PARKTRONIC is switched
off, Active Parking Assist is also unavailable.
Use Active Parking Assist for parking spaces:
R that are parallel to the direction of travel
R that are on straight roads, not bends
R that are on the same level as the road, e.g.
not on the pavement
Parking Important safety notes
Objects located 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 calculated, e.g. overhanging
loads, tail sections or loading ramps of goods
vehicles. In some circumstances, Active Parking Assist may therefore guide you into
the parking space too early. G
WARNING
If there are objects above the detection range,
Active Parking Assist may turn prematurely.
You may cause a collision as a result. There is
a risk of an accident.
If there are objects above the detection range,
stop and deactivate Active Parking Assist. G
WARNING
Active Parking Assist merely aids you by
intervening actively in the steering. If you do
not brake there is a risk of an accident.
Always apply the brakes yourself when
maneuvering and parking.
Detecting parking spaces Example: detected parking space
Active Parking Assist is switched on
automatically when driving forwards. The
system is 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. When driving at speeds below
19 mph (30 km/h), you will see parking
symbol 0003as a status indicator in the
instrumentc luster. When a parking space has
been detected, an arrow towards the right
0027 or the left 0002also appears.
By default, Active Parking Assist only displays
parking spaces on the front-passenger side.
Parking spaces on the driver's side are
displayed as soon as the tur nsignal on the
driver's side is activated. If you wish to park
in a space on the driver's side, the indicator
on the driver's side must remain on. The turn
signal must remain switched on until you Driving systems
