R
at any time, you can intervene in the steer-

when transporting a load which protrudes
from your vehicle, you should not use
Active Parking Assist.
R
never use Active Parking Assist when snow
chains are fitted.
R
make sure that the tyre pressures are
always correct. This has a direct influence

General notes
Active Parking Assist is an electronic parking
aid with ultrasound. Ultrasound is used to
measure the road on both sides of the vehicle.
A suitable parking space is indicated by the
parking symbol. Active steering intervention
can assist you during parking.
You may also use PARKTRONIC
(
Y page 182). When PARKTRONIC 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
Detecting parking spaces
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.
G WARNING
If objects are located above the detection
range, Active Parking Assist may start to steer
into the parking space too soon. As a result,
you could cause a collision. There is a risk of
an accident.
If objects are located above the detection
range, stop the vehicle and switch Active
Parking Assist off.
For further information on the detection
range (
Y page 183).
Active Parking Assist does not support you
parking in spaces that are parallel to the
direction of travel if:
R
the parking space is on a kerb stone
R
the parking space appears to be blocked,
for example by foliage or grass paving
blocks
R
the range of movement is too small
R
the parking space is bordered by an obsta-
cle which is not clearly defined such as a
tree or a trailer

Active Parking Assist is activated automati-
cally 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 the vehicle.
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
i In the case of parking spaces that are at
right angles to the direction of travel,
please ensure that the parking space is
long enough to accommodate your vehicle.
