parking assi stance sy stem with ultrasound. It
monitors the area around your vehicle using six
sensors 1inthe front bumper and six sensors
in there ar bumper. Parking Assist PARKTRONIC
indicates visually and audibly the dis tance
between your vehicle and an object.
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
to ne sounds from a di stance of appr oximately
0.3 m toan obs tacle. A continuous tone sounds
from a di stance of appr oximately 0.2 m. You can
set thewa rning tone in the multimedia sy stem
so that it will sound earlier at a greater dis tance
of appr oximately 1.0 m (→ page197).
