Tips for driving with DISTRONIC PLUS General notes
The following contains description
sofcertain
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 detec
tvehicles
traveling on adifferent line. The distance to
the vehicle in fron twill be too short. Other vehicles changing lanes
DISTRONIC PLUS has not detected the
vehicle cuttin
ginyet. The distanc etothis
vehicle will be too short.
Narrow vehicles DISTRONIC PLUS has not yet detected the
vehicle in front on the edge of the road,
because of its narrow width
.The distance to
the vehicle in front will be too short.
Obstructions and stationary vehicles DISTRONIC PLUS does not brake for
obstacles or stationary vehicles. If, for170
Driving systemsDriving and parking

example, the detected vehicle turn
sacorner
and reveals an obstacle or stationary vehicle,
DISTRONIC PLUS will not brake for these.

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 four 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
replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking
and exiting
aparking 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 172
Driving systemsDriving and parking

truck or
apneumati cdrill coul dcause
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 (18 km/h) .Itisreactivated at lower
speeds.
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. 001A
Sensors in the front bumper, left-hand
side (example) Side view Top view
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
