Important safety notes G
WARNING
Active Parking Assist is merely an aid and may
sometimes recommend parking spaces that
are not suitable for parking. For example,
these might be spaces where parking is pro-
hibited, driveways, unsuitable surfaces, etc.
Active Parking Assist measures the parking
space as you drive past it. Any later changes
to the parking space are not taken into
account. For instance, this may be the case
when the vehicle parked in front of or behind
the space changes its position or when an
obstacle is moved into the parking space.
Active Parking Assist does not relieve you of
the responsibility of paying attention. If you
rely solely on Active Parking Assist, you could cause an accident and injure yourself and oth-
ers.
You are always responsible for safety and
must continue to pay attention to your imme-
diate surroundings when parking and
manoeuvring.
G
WARNING
Objects located 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 calculated, e. g. overhanging
loads, tail sections or loading ramps of goods
vehicles. In some circumstances, Active Park-
ing Assist may therefore guide you into the
parking space too early. This may lead to a
collision. For this reason, you should avoid
using Active Parking Assist in such situations. 194

G
WARNING
The front of the vehicle will veer out in the
direction of the oncoming traffic during the
parking operation. In some cases the vehicle
will also take you onto sections of the oncom-
ing lane during the parking procedure.
You are responsible for safety at all times and
must pay attention to any road users
approaching or passing. Stop the vehicle if
necessary or cancel the Active Parking Assist
parking procedure. G
WARNING
Make sure that no persons or animals are in
the manoeuvring range. Otherwise, they
could be injured.
! If unavoidable, you should drive over
obstacles such as kerbs slowly and not at
a sharp angle .Otherwise, you may damage
the wheels or tyres.
Active Parking Assist is an electroni cparking
aid with ultrasound. Ultrasound is used to
measure the road on both sides of the vehicle.
As uitable parking space is indicated by the
parking symbol. Active steering intervention
can assis tyou during parking. You may also
use PARKTRONIC (Y page 191). When PARK-
TRONIC is switched off, Active Parking Assist
is also unavailable.
Use Active Parking Assist for parking spaces:
R that are parallel to the direction of travel
R that are on straight roads, not bends
R that are on the same level as the road, e.g.
not on the pavement
Parking tips:
R on narrow roads, drive as closely as possi-
ble past the parking space.
R parking spaces that are littered, overgrown
or partially occupied by trailer drawbars
might be identified incorrectly or not at all.
R snowfall or heavy rain may lead to a parking
space being measured inaccurately. R
pay attention to the PARKTRONIC
(Y page 193) warning messages during the
parking procedure.
R at any time, you can intervene in the steer-
ing procedure to correct it. Active Parking
Assist will then be cancelled.
R when transporting a load which protrudes
from your vehicle, you should not use
Active Parking Assist.
R when snow chains or an emergency spare
wheel are fitted, you should not use Active
Parking Assist here either.
R make sure that the tyre pressures are
always correct. This has adirec tinfluence
on the parking characteristics of the vehi-
cle.
R the way your vehicle is positioned in the
parking space after parking is dependent
on various factors .These include the posi-
tion 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 a
parking space, or not far enough into it. In
some cases, it may also lead you across or
onto the kerb. If necessary, you should can-
cel the parking procedure with Active Park-
ing Assist.
R you can also engage forward gear prema-
turely. The vehicle redirects and does not
drive as far into the parking space. Should
a gear be changed too early to achieve a
sensible parking position, the parking pro-
cedure will be cancelled. Driving systems

Detecting parking spaces
Example: detected parking space
:
Detected parking space on the left
; Parking symbol
= Detected parking space on the right
Active Parking Assis tisswitched on automat-
ically when driving forwards. The system is
operational at speeds of up to approximately
35 km/h. While in operation, the system inde-
pendently locates and measures parking
spaces on both sides of th evehicle. When
driving at speeds below 30 km/h, you will see
the parking symbol as a status indicator in the
instrumen tcluster .Active Parking Assist only
displays parking spaces on the front-
passenger side as standard .Parking spaces
on the driver's side are displayed as soon as
the tur nsignal on the driver's side is activa-
ted. To park on the driver's side, you must
leave the driver's side tur nsignal switched
on. This must remain switched on until you
acknowledge the use of Active Parking Assist
by pressing the abutton on the multi-
function steering wheel.
When a parking space has been detected, an
arrow towards the right or the left also
appears.
Active Parking Assist will only detect parking
spaces:
R that are parallel to the direction of travel
R that are at least 1.5 m wide
R that are at least 1.3 m longer than your
vehicle
Ap arking space is displayed while you are
driving past it, and until you are approx-
imately 15 m away from it. Parking G
