drive the vehicle closer to the obstacle
than the minimum distance.Warning displays

The warning display is divided into 5 yellow
and 2 red segments for each side of the ve-
hicle. Parktronic is operational if yellow in-
dicator segments3 and5 light up.The selector lever position determines
whether the front and/or rear area is mon-

\4sixth segment, an intermittent warning
tone sounds for approximately

\4seventh segment, a continuous warn-
ing tone sounds. You have reached the
minimum distance.
Roll-back warning
Parktronic automatically begins to monitor
the area behind the vehicle if the vehicle
begins to roll backwards without reverse
gear engaged, e.g. after stopping on an up-
hill gradient.
