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

vehicles. In some circumstances, Active Park-
ing Assist may therefor eguide you into the
parking space too early. This may lead to a
