Active Parkin gAssist is merely an aid and may
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 insta nce,this ma ybethe case
when the vehicle parked in front of or behind
the space changes its position or when an
obstacle is moved int othe parkin gspace.
Active Parking Assist does not reliev eyou of
the responsibilit yofpaying attention. If you

Parking tips:
R on narrow roads, driv easclosely as possi-
ble past the parkin gspace.
R parking spaces that are littered, overgrown
or partially occupied by trailer drawbars
