sometimes recommen dparking spaces that
are not suitable for parking. For example,
these might be spaces where parking is pro-
hibited ,driveways, unsuitabl esurfaces, etc.
Active Parking Assis tmeasures the parking
space as you driv epast 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 positio norwhen an
obstacle is moved int othe parkin gspace.
Active Parking Assist does not reliev eyou of
the responsibilit yofpaying attention. If you
rely solel yonA ctive Parkin gAssist, you could cause an acciden

diate surroundings whe nparking and
manoeuvring. G
WARNING
Objects located above the heigh trange of
Active Parking Assis twill 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 therefor eguide you into the
parking space too early. This may lead to a
collision. For this reason, you should avoid
using Active Parking Assis tinsuch situations. Driving systems
