Risk of accident
The vehicle can be braked when DISTRONIC
PLUS is activated. For this reason, deactivate
DISTRONIC PLUS if the vehicle is to be set in
motion by othe rmeans (e.g. in acar wash or
by towing).
You can activate DISTRONIC PLUS in the fol-
lowing circumstances:
R if the engine has been started and you have
been drivin gfor up to two minutes
R if the parkin gbrake is not applied
R if ESP ®
is acti vated
R if the transmission is in position D
R if the bonnet is closed
R if the driver' sdoor is closed and you shift
from Pto Dor your seat belt is fastened
R if the front-passenger door is closed
Activating while driving
When drivin gatspeeds below 30 km/h, you
can only acti vate DISTRONIC PLUS if the vehi-
cle in fron thas been detected and is shown
in the multifunction display. If the vehicle in
front is not shown in the multifunction display
and is no longe rbeing detected, because it
has changed lanes, for example, DISTRONIC
PLU Sisd eactivated and atone sounds. 162

Important safety notes G
Risk of accident
PARKTRONIC is only an aid and may not
detect all obstacles .This system does not
reliev eyou of the need to pay attention.
You are always responsible for safet yand
must continue to pay attention to your imme-

manoeuvring. You could otherwise endanger
yourself and others. G
Risk of injury
Make sure that no persons or animals are in
the manoeuvring range. Otherwise ,they
coul dbei njured.
PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It indicates visual lyand
audibly the distance between your vehicle
and an object.
PARKTRONIC is activated automatically when
you:
R switch on the ignition
R release the parking brake
PARKTRONIC is deactivated at speeds above
18 km/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. 174

X Switch the ignition back on. The problem may be caused by an exter
nalsource of radio or
ultrasoun dwaves.
X See if PARKTRONIC functions in adifferent location. Parking Guidance
Important safet ynotes Parking Guidance is an electronic parking aid
with ultrasound. Ultrasound is used to meas-
ure the road on both sides of the vehicle. A
suitable parking space is indicated by the
parking symbol. You receiv esteering instruc-
tions when parking. You may also use PARK-
TRONIC (Y page 174). G
Risk of accident
Parking Guidance is merely an aid and may
recommen dparking spaces that are not suit-
able for parking. For example, these might be
spaces where parking is prohibited ,drive-
ways, unsuitabl esurfaces, etc.
Parking Guidance measures the parking
space as you drive past it. Any later changes
to the parking space are not taken into
account. For instance, this may be the case when the vehicle parked in front of or behind
the space changes its position or when an
obstacle is moved into the parking space.
Parking Guidance does not relieve you of the
responsibility for paying attention. If you rely
solely on Parking Guidance, you could cause
an accident and injure yourself and others.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring.
G
Risk of accident
Objects located above the height range of
Parking Guidance will not be detected when
the parking space is measured. Thes eare not
take ninto account whe nthe parkin gproce-
dure is calculated, e.g .overhanging loads ,tail
sections or loading ramps of good svehicles.
