Tips for driving with DISTRONIC PLUS General notes
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. Driving systems
177Driving and parking Z

Cornering, going into and coming out of a
bend
The ability of DISTRONIC PLU
Sto 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,
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, for
example, the detected vehicle turns a corner
and reveals an obstacle or stationary vehicle,
DISTRONIC PLUS will not brake for these.178
Driving systemsDriving and parking

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

The vehicle is kept stationary without the
driver having to depress the brake pedal.
The braking effect is canceled and the HOLD
function deactivated when you depress the
accelerator pedal to pull away.
i Do not use the HOLD function when
driving off-road, on steep uphill or downhill
gradients or on slippery or loose surfaces.
The HOLD function cannot hold the vehicle

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 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 detec tsuch objects
when they are in the immediate vicinity of
the vehicle. You could damag ethe 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 180
Driving systemsDriving and parking

truck or a pneumati
cdrill 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 parking brake
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). It is reactivated at lower
speeds.
PARKTRONIC monitors the area around your
vehicle using six sensors in the front and four
sensors in the rear. 0002
Sensors in the front bumper, left-hand
side (example)
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
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
