Important safet ynotes Active Parking Assist is an electronic parking
aid with ultrasound. Ultrasound is used to
measure the road on both sides of the vehicle.
As uitable parking space is indicated by the

TRONIC is switched off, Active Parking Assist
is also unavailable. G
WARNING
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
rely solel yonA ctive Parkin gAssist ,you could

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, driv easclosely as possi-
ble past the parkin gspace.
R parking spaces that are littered, overgrown
or partially occupied by trailer drawbars
might be identified incor rectly or not at all.

on the parking characteristics of the vehi-
cle.
R the wa yyourv ehicle is positioned in the
parking space after parking is dependent
on various factor s. Theseinclude the posi-
tion and shape of the vehicles parked in
front and behind it and the conditions of the
location. In some cases, Active Parking
