nction of Parking Assist PARKTRONIC
Pa rking Assist PARKTRONIC is an electronic
parking assi stance sy stem with ultrasound. It
monitors the area around your vehicle using mul‐
tiple sensors on the front bumper and on the
re ar bumper. Parking Assist PARKTRONIC sho ws
yo uth e dis tance between your vehicle and a
de tected obs tacle visually and audibly.
Pa rking Assist PARKTRONIC is on lyan aid. It is
not a substitute foryo ur attention tothe sur‐
ro undings. The responsibility for safe manoeu‐
vring and parking remains with you. Make sure
th at there are no persons, animals or objects in
th e manoeuvring area while manoeuvring and
parking in/exiting parking spaces.
In thest andard setting, an intermit tent wa rning

0.3 m toan obs tacle in front and appr oximately 1.
0 m toan obs tacle behind. A continuous warn‐
ing tone sounds from a di stance of appr ox‐
imately 0.2 m. Using theWarn early setting in
th e multimedia sy stem, thewa rning tones for
front and side impact pr otection can be set to
sound at a greater dis tance of appr oximately
1. 0 m in front and 0.6 m on the sides
(/ page 220).
