PARKTRONIC
General notes
PARKTRONIC is an electronic parking aid. The
system is equipped with ultrasonic sensors in
the front and rear bumpers to monitor the area
around your vehicle. PARKTRONIC indicates vis-
uallya nd audibly the distance between your
vehicle and an object.
Your vehicle features two separate sound emit-
ters with different frequencies for the warning
tones. The warning ranges in front of and behind the vehicle are indicated by different warning
tones.
PARKTRONIC is activated automatically when
you:
Rturn the key to position 2in the ignition lock
Rrelease the parking brake and
Rmove the selector lever to D,Nor R
PARKTRONIC is deactivated at speeds above
11 mph (18 km/h). PARKTRONIC is reactivated
at speeds below 10 mph (16 km/h).
Important safety notes
PARKTRONIC is only an aid. It cannot replace
your own awareness of the immediate surround-
ings. You are responsible for safe maneuvering,
parking and pulling away.W hen maneuvering,
parking and pulling away,m ake sure that there
are no persons, animals or object sinthe maneu-
vering area.
!Pay particular attention to obstacles above
or below the sensors when parking, such as
flower pots or trailer towbars. PARKTRONIC
does not recognizes uch objectswhen they
are in the immediate vicinity of the vehicle.
You could damage the vehicle or objects.
PARKTRONIC can suffer interference from:
Rultrasonic sources such as atruck's
compressed-air brakes, an automatic car
wash or apneumatic drill
Rattachments to the vehicle, e.g. rear moun-
ted racks
Rnumber plates (vehicle license plates) that
are not affixed flat against the bumper
Rdirty or icy sensors
Remove adetachable trailer coupling if it is no
longer required. PARKTRONIC measures the
minimum detection range to an obstacle from
the bumper, not the ball coupling.

Active Parking Assist
General notes
Active Parking Assist is an electronic parking
aid. The system uses ultrasound sensors to
measure the road on both sides of the vehicle
and indicates suitable parking spaces. It can
then actively steer and brake the vehicle to help
you to park and exit the parking space.
Active Parking Assist includes the PARKTRONIC
parking aid which indicates visuallya nd audibly
the distance between your vehicle and an
object .Todot his, PARKTRONIC uses the ultra-
sonic sensors of the Active Parking Assist
(
Ypage 150).
Important safety notes
Active Parking Assist is only an aid. It is not a
substitute for your attention to the immediate
surroundings. You are responsible for safe maneuvering, parking and pulling away.M
ake
sure that no persons, animals or object sare in
the maneuvering range.
When you deactivate PARKTRONIC, Active Park-
ing Assist will also be deactivated.
For vehicles with atrailer coupling installed, the
minimum length for parking spaces will be
slightly increased.
If you have attached atrailer to your vehicle, you
should not use Active Parking Assist. Once the
electrical connection is established between
your vehicle and the trailer, Active Parking
Assist is no longer available. PARKTRONIC is
then deactivated for the rear area.
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.
154Driving systems
Driving and parking

Pay attention to other road users. Stop the
vehicle if necessary or cancel the Active Park-ing Assist parking procedure.
!If unavoidable, you should drive over obsta-
cles such as curbs slowly and not at asharp
angle. Otherwise, you may damage the
wheels or tires.
Active Parking Assist may also display spaces
not suitable for parking, e.g.:
Rin az onew here parking or stopping is pro-
hibited
Rin frontofd riveways or entrances and exits
Ron unsuitable surfaces
Parking tips:
Ron narrow roads, drive as closely as possible
past the parking space.
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 PARKTRONIC warning
messages (Ypage 152) during the parking
procedure.
Ryou can intervene in the steerin gprocedure to
correctitata ny time. Parking assistanc ewill
then be canceled and Active Parking Assist
stopped.
Rwhen transportin gaload which protrudes
from your vehicle, you should not use Active
Parking Assist.
Rnever use Active Parking Assist when snow
chains are installed.
Ralwayse nsure that the tire pressure is cor-
rect.T his has adirect influenc eonthe parking
characteristics of the vehicle.
Use Active Parking Assist for parking spaces
that are:
Rparallel or at right angles to the direction of
travel.
Ron straight roads, not bends
Ron the same level as the road, e.g. not on the
pavement
Detecting parking spaces
GWARNING
If there are object sabove the detection range:
RActive Park Assist may steer too early
Rthe vehicle may not stop in frontoft hese
objects
You may cause acollision as aresult. There is
ar isk of an accident.
If object sare located above the detection
range, stop and deactivate Active Parking
Assist.
Objectsl ocated above the height range of Active
Parking Assist will not be detected when the
parking space is measured. These are not taken
into account when the parking procedure is cal-
culated, e.g. overhangin gloads, tail sections or
loading ramps of goods vehicles.
For further information on the detection range
(
Ypage 151).
Active Parking Assist does not assist you park-
ing in spaces at right angles 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
Active Parking Assist does not assist you park-
ing in spaces that are parallel or at right angles
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

Active Parking Assist no longer supports you
with steering interventions and brake applica-
tions. Once active parking assistance has been
stopped, you must steer and brake again your-
self. PARKTRONIC is still available.
Parking tips:
RThe way your vehicle is positioned in the park- ing space after parking is dependent on vari-
ous factors. These include the position and
shape of the vehicles parked in front and
behind it and the conditionsoft he location. It
may be the case that Active Parking Assist
guides you too far into aparking space, or not
far enough into it. In some cases, it may also
lead you across or onto the curb. In this case,
cancel the active parking assistance.
RYou can also preselect transmission position
D.T he vehicle redirects and does not drive as
far into the parking space. If you change direc-
tion too early, parking assistance is canceled
and Active Parking Assist is stopped. It is then
not possible to achieve asensible parking
position from the current position.
Exiting aparking space
In order that Active Parking Assist can support
you when you exit the parking space:
Rthe border of the parking space must be high
enough at the front and the rear. Acurb is too
small, for example.
Rthe border of the parking space must not be
too wide. Your vehicle can be maneuvered
into aposition at amaximum of 45° to the
startin gposition in the parking space.
Ram aneuvering distance of at least 3.3 ft
(1.0 m) must be available.
Active Parking Assist can only assist you with
exiting aparking space if you have parked the
vehicle parallel to the direction of travel using
Active Parking Assist.
If PARKTRONIC detects obstacles, Active Park-
ing Assist brakes automatically when exiting
from the parking space. You are responsible for
