Parking Assist PARKTRONIC
Important safety notes
Parking Assist PARKTRONIC is an electronic
parking aid with ultrasound. It monitor sthe area
around your vehicle using six sensors in the
front bumper and six sensors in the rear
bumper. Parking Assist PARKTRONIC visually
and audibly indicates the distance between your
vehicle and an object.
Parking Assist PARKTRONIC is only an aid. It is
not areplacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking and
exiting aparking space. Make sure that there
are no persons, animals or object sinthe maneu-
vering area while maneuvering and parking in/
leaving parking spaces.
!When parking, pay particular attention to
object sabove or below the sensors, such as
flower pots or trailer drawbars. Parking Assist
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
object sthat absorb ultrasonic waves.
Ultrasonic sources such as an automatic car
wash, the compressed-air brakes of atruck or
ap neumatic drill could cause Parking Assist
PARKTRONIC to malfunction.
Parking Assist PARKTRONIC may not function
correctly on uneven terrain.
Parking Assist PARKTRONIC is activated auto-
matically when you:
Rswitch on the ignition
Rshift the transmission to position h,kor
i
Rrelease the electric parking brake Parking Assist PARKTRONIC is deactivated at
speeds above 11 mph (18 km/h). It is reactiva-
ted at lower speeds.
Range of the sensors
General notes
Parking Assist PARKTRONIC does not take into
account obstacles located:
Rbelow the detection range, e.g. people, ani-
mals or objects.
Rabove the detection range, e.g. overhanging
loads, tail section
sorloading ramps of trucks.
:Sensors in the front bumper, left-hand side
(example)
The sensors must be free from dirt, ice or slush.
They can otherwise not function correctly. Clean
the sensors regularly,t aking care not to scratch
or damage them (

Parking Pilot
General notes
Parking Pilot is an electronic parking aid with
ultrasound. It measures the road on both sides
of the vehicle. Aparking symbol indicates asuit-
able parking space. Active steering intervention
and brake application can assist you during
parking and when exiting aparking space. Park-
ing Assist PARKTRONIC is also available
(
Ypage 161).
Important safety notes
Parking Pilot is only an aid. It is not areplace-
ment for your attention to your immediate sur-
roundings. You are always responsible for safe
maneuvering, parking and exiting aparking
space. Make sure that no persons, animals or
object sare in the maneuvering range.
When Parking Assist PARKTRONIC is deactiva-
ted, Parking Pilot is also unavailable.
GWARNING
While parking or pulling out of aparking
space, the vehicle swings out and can drive
onto areas of the oncomingl ane. This could
result in acollision with another road user.
There is arisk of an accident.
Pay attention to other road users. Stop the
vehicle if necessary or cancel the Parking Pilot
parking procedure.
!If unavoidable,y ou should drive over obsta-
cles such as curbs slowly and not at asharp
angle. Otherwise, you may damage the
wheels or tires.
Parking Pilot may also display spaces not suita-
ble for parking, e.g.:
Rwhere parking or stopping is prohibited
Rin front of driveways or entrances and exits
Ron unsuitable surfaces
Parking tips:
ROn narrow roads, drive as close to the parking
space as possible.
RParking spaces that are littered or overgrown
might be identified or measured incorrectly.
RParking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly.
RSnowfall or heavy rain may lead to aparking
space being measured inaccurately.
RPay attention to the warning messages of
Parking Pilot PARKTRONIC during the parking
procedure (
Ypage 162).
RYou can intervene to correct the steering pro-
cedure at any time. Parking Pilot will then be
canceled.
RWhen transporting aload that protrudes from
your vehicle, you must not use Parking Pilot.
RNever use Parking Pilot when snow chains are
mounted.
RMake sure that the tire pressures are always
correct.T his hasadirect influence on the
parking characteristics of the vehicle.
Use Parking Pilot for parking spaces that are:
Rthat are paralleloratr ight-angles to the direc-
tion of travel
Ron straight roads, not bends
Ron the same level as the road, e.g. not on the
pavement
Detecting parking spaces
Object slocated above the detection range of
Parking Pilot will not be detected when the park-
ing space is measured. These are not taken into
account when the parking procedure is calcula-
ted, e.g. overhanging loads, truck overhangs or
loading ramps. Parking Pilot may therefore
guide you into the parking space too early.
Parking Pilot does not assist you parking in
spaces perpendicular to the direction of travel if:
Rtwo parking spaces are located directly next
to one another
Rthe parking space is directly next to alow
obstacle such as alow curb
Ryou forward-park
Parking Pilot does not assist you parking in
spaces parallelorp erpendicular to the direction
of travel if:
Rthe parking space is on acurb
Rthe system reads the parking space as being
blocked, for example by foliage or grass pav-
ing blocks
Rthe area is too small for the vehicle to maneu-
ver into
Rthe parking space is bordered by an obstacle,
e.g. atree, apost or atrailer

GWARNING
If there are objects above the detection range:
RParking Pilot may steer in too early
Rthe vehiclem ay not stop in front of these
objects
You may caus eacollision as aresult. There is
ar isk of an accident.
If objects are located above the detection
range, stop and deactivate Parking Pilot.
:Detected parking space on the left
;Parking symbol
=Detected parking space on the right
Parking Pilot is activated automatically when
driving forward. The system is operational at
speeds of up to approximately 22 mph
(35 km/h) .Whileino peration, the system inde-
pendently locates and measures parking spaces on both sidesoft he vehicle.
Parking Pilot wil lonly detect parking spaces:
Rthat are paralleloratr ight-angles to the direc-
tion of travel
Rthat are paralleltot he direction of travel and
at least 59 in (1.5 m) wide
Rthat are paralleltot he direction of travel and
at least 39.5 in (1.0 m)longer than your vehi-
cle
Rat right angles to the direction of travel and at
least 39.5i n(1.0m )wider than your vehicle
iNotet hat Parking Pilot cannot measure the
lengt hofap arking space if it is at right angles
to the direction of travel. You will need to
judge whether your vehicle will fit int othe
parking space.
When drivingats peeds below 19 mph
(30 km/h), you will see parking symbol ;as a
status indicator in the instrumentc luster. When
ap arking space has been detected, an arrow
towards the right or the left also appears. Park-
ing Pilot only displays parking spaces on the
front-passenge rside as standard. Parking
spaces on the driver's side are displayed as soon as the turn signal on the driver's side is
activated. When parking on the driver's side,
this must remain activated until you confirm the
use of Parking Pilot by pressing the
abutton
on the multifunction steeringw heel. The system
automatically determines whether the parking
space is parallel or at right-angles to the direc-
tion of travel.
Ap arking spac
e is displayed while you are driv-
ing past it, and until you are approximately 50 ft
(15 m) away fromi t.

Parking tips:
RThe way you rvehicle is positioned in the park-
ing space after parking is dependent on vari-
ous factors. These include the positiona nd
shape of the vehiclesp arked in front and behind it and the conditions of the location. It
may be the case that Parking Pilotg
uides you
too far into aparking space, or not far enough
into it. In some cases, it may also leady ou
across or onto the curb. If necessary ,you
shoul dcancel the parking procedure with
Parking Pilot.
RYou can also preselect transmission position
h.T he vehicle redirects and does not drive
as far into the parking space. Should the
transmission change take place too early, the parking procedure is canceled. Asensible
parking positionc an no longer be achieved

Exitingap arking space
In order for Parking Pilottos upport you when
exiting the parking space:
Ryou need to have parked using Parking Pilot.
Rthe border of the parking space must be high enough at the front and the rear. Acurb stone
is too small,f or example.
Rthe border of the parking space must not be
too wide, as the positionoft he vehicle must
not exceed an angle of 45° to the starting
positionasitism aneuvered into the parking
space.
