Active Parking Assist
General notes
Active Parking Assist is an electronic parking aid
with ultrasound. It measures the road on both
sides of the vehicle. Aparking symbol indicates
as uitable parking space. Active steering inter-
vention and brake application can assist you
during parking and when exiting aparking
space. You may also use PARKTRONIC
(
Ypage 174).
Important safety notes
Active Parking Assist is merely an aid. It is not a
replacement for your attention to your immedi-
ate surroundings. You are always responsible
for safe maneuvering, parking and exiting a
parking space. Make sure that no persons, ani-
mals or object sare in the maneuvering range.
When PARKTRONIC is switched off, Active Park-
ing Assist 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 inacollision with another road user.
There is arisk of an accident.
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.:
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 PARKTRONIC
(Ypage 176) warning messages during the
parking procedure.
RYou can intervene in the steerin gprocedure
to correctitata ny time. Active Parking Assist
will then be canceled.
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.
RMake sure that the tire pressures are always
correct. This has adirect influenc eonthe
parking characteristics of the vehicle.
Use Active Parking Assist for parking spaces:
Rparallel or at right angles to the direction of
travel
Rthat are on straight roads, not bends
Rthat are on the same level as the road, e.g. not on the pavement
Detecting parking spaces
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.
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.
For further information on the detection range
(
Ypage 175). 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 park forwards
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
:Detected parking space on the left
;Parking symbol
=Detected parking space on the right
Active Parking Assist is switched on automati-
cally when driving forwards. The system is
operational at speeds of up to approximately
22 mph (35 km/ h).W hile in operation, the sys-
tem independentl yloc ate sand measures park-
ing spaces on both sides of the vehicle.
Active Parking Assist will only detect parking
spaces:
Rparalle loratr ight angle stothe direction of
travel
Rthat are paralle ltothe direction of travel and
at leas t59in(1.5 m) wid e

at leas t39.5 in (1.0 m)longer than your vehi-
cle
Rthat are at right angles to the direction of
travel and at least 39.5i n(1.0m )wider than
your vehicle
iNotet hat Activ eParking Assist cannot
measure the size of aparking space if it is at
right angles to the direction of travel. You will
need to judge whether your vehicle will fit into the parking space.
When drivingats peeds below 19 mph
(3 0k m/ h),y ou will see the 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. By
default,A ctiveP arking Assist only displays park-
ing spaces on the front-passenge rside. 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 switched on until you acknowl-
edge the use of Activ eParking Assist by press-
ing the abutton on the multifunction steer-
ing wheel. The system automatically determines
whether the parking space is parallel or at right
angles to the direction of travel.
Ap arking space is displayed while you are driv-
ing past it, and until you are approximately 50 ft (1 5m)a way fromi t.

GWARNING
If you leave the vehicle when it is only being
braked by Activ eParking Assist it could roll

partment, the battery or the fuses have
been tampered with.

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 conditions of the 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 ontot he curb. If necessary,
you should cancel the parking procedure with
Active Parking Assist.
RYou can also select preselect transmission
position D.The vehicle redirectsa nd does not
drive as far into the parking space. Should the
transmission change take place too early, the
parking procedure will be canceled. Asensi-
ble parking position can no longer be ach-
ieved from this 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, as the position of the vehicle must
not exceed an angle of 45° to the starting
position as it is maneuvering into 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
exitin gaparking space if you have parked the vehicle parallel to the direction of travel using
Active Parking Assist.
iIf PARKTRONIC detect
sobstacles, Active
Parking Assist brakes automatically whilst the
vehicle exits the parking space. You are
responsible for braking in good time.
