Visual signals indicate to the driver the rel-
ative distance between the sensors and an
obstacle. The warning indicator for the
front area is located above the center air
vents in the dashboard. The warning indi-
cator for the rear area is integrated in the
rear trim.Front area warning indicator1Left side of the vehicle
2Right side of the vehicleEach warning indicator is divided into six
yellow and two red segments for either
side of the vehicle. The Parktronic system
is ready when the border around the indi-
cator is illuminated.
The position of the gear selector lever de-
termines which warning indicators will be
activated.As your vehicle approaches an object, one
or more segments will light up, depending
on the distance. When the eighth segment
lights up, you have reached the minimum
distance.
Front area: An intermittent acoustic
warning will sound as the seventh seg-
ment lights up and a constant acoustic
warning lasting a maximum of three
seconds will sound for the eighth seg-
ment.
Rear area: An intermittent acoustic
warning will sound when the first seg-
ment lights up. This signal quickens
with each additional segment lit. When
the eighth segment illuminates, the
acoustic warning becomes a constant
signal. The signal is canceled when the
selector lever is placed in position D
