Parking Assist PARKTRONIC
Important safety notes Parking Assist PARKTRONIC is an electronic
parking aid with ultrasound. It monitor st he 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 ar eplacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking and
exiting ap arking space. Make sure that there
are no persons, animals or object sint he maneu-
vering area while maneuvering and parking in/
leaving parking spaces.
! When parking, pay particular attention to
object sa bove 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 st hat absorb ultrasonic waves.
Ultrasonic sources such as an automatic car
wash, the compressed-air brakes of at ruck 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: R
switch on the ignition R
shift the transmission to position [ , ^ or
\\ R
release 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: R
below the detection range, e.g. people, ani-
mals or objects. R
above the detection range, e.g. overhanging
loads, tail section sorl oading ramps of trucks.
C
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 ( Y

Parking Pilot
General notes Parking Pilot is an electronic parking aid with
ultrasound. It measures the road on both sides
of the vehicle. Ap arking symbol indicates as uit-
able parking space. Active steering intervention
and brake application can assist you during
parking and when exiting ap arking space. Park-
ing Assist PARKTRONIC is also available
( Y
page 161).
Important safety notes Parking Pilot is only an aid. It is not ar eplace-
ment for your attention to your immediate sur-
roundings. You are always responsible for safe
maneuvering, parking and exiting ap arking
space. Make sure that no persons, animals or
object sa re in the maneuvering range.
When Parking Assist PARKTRONIC is deactiva-
ted, Parking Pilot is also unavailable.
G WARNING
While parking or pulling out of ap arking
space, the vehicle swings out and can drive
onto areas of the oncomin gl ane. This could
result in ac ollision with another road user.
There is ar isk 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 as harp
angle. Otherwise, you may damage the
wheels or tires.
Parking Pilot may also display spaces not suita-
ble for parking, e.g.: R
where parking or stopping is prohibited R
in front of driveways or entrances and exits R
on unsuitable surfaces
Parking tips: R
On narrow roads, drive as close to the parking
space as possible. R
Parking spaces that are littered or overgrown
might be identified or measured incorrectly. R
Parking spaces that are partially occupied by
trailer drawbars might not be identified as
such or be measured incorrectly. R
Snowfall or heavy rain may lead to ap arking
space being measured inaccurately. R
Pay attention to the warning messages of
Parking Pilot PARKTRONIC during the parking
procedure ( Y
page 162). R
You can intervene to correct the steering pro-
cedure at any time. Parking Pilot will then be
canceled. R
When transporting al oad that protrudes from
your vehicle, you must not use Parking Pilot. R
Never use Parking Pilot when snow chains are
mounted. R
Make sure that the tire pressures are always
correct .T his has ad irect influence on the
parking characteristics of the vehicle.
Use Parking Pilot for parking spaces that are: R
that are paralle loratr ight-angles to the direc-
tion of travel R
on straight roads, not bends R
on the same level as the road, e.g. not on the
pavement
Detecting parking spaces Object sl ocated 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: R
two parking spaces are located directly next
to one another R
the parking space is directly next to al ow
obstacle such as al ow curbR
you forward-park
Parking Pilot does not assist you parking in
spaces paralle lorp erpendicular to the direction
of travel if: R
the parking space is on ac urbR
the system reads the parking space as being
blocked, for example by foliage or grass pav-
ing blocks R
the area is too small for the vehicle to maneu-
ver into R
the parking space is bordered by an obstacle,
e.g. at ree, ap ost or at railer

Parking tips: R
The way you rv ehicle is positioned in the park-
ing space after parking is dependent on vari-
ous factors. These include the positio na nd
shape of the vehicle sp arked in front and behind it and the conditions of the location. It
may be the case that Parking Pilo tg uides you
too far into ap arking space, or not far enough
into it. In some cases, it may also lea dy ou
across or onto the curb. If necessary ,y ou
shoul dc ancel the parking procedure with
Parking Pilot. R
You can also preselect transmission position
[ .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. As ensible

Exitin gap arking spaceIn order for Parking Pilo ttos upport you when
exiting the parking space: R
you need to have parked using Parking Pilot. R
the border of the parking space must be high
enough at the front and the rear. Ac urb stone
is too small ,f or example. R
the border of the parking space must not be
too wide, as the positio noft he vehicle must
not exceed an angle of 45° to the starting
positio nasitism aneuvered into the parking
space. R
am aneuvering distance of at least 3.3 ft
(1.0 m) must be available.
Parking Pilo tc an assist you with exiting ap ark-
ing space only if you have parked the vehicle
