Front sensors
Rear sensorsMinimum distance

range, all the warning lamps light up and
you hear a warning signal. If the obstacle is
closer than the minimum distance, the ac-
tual distance might no longer be indicated
by the system.
Warning indicators
1Left front area warning indicator2Right front area warning indicator
Visual signals indicate to the driver the rel-
ative distance between the sensors and an
obstacle. The warning indicators for the
front area are located above the left air
vents1 and center air vents2 in the dash-
board. The warning indicator for the rear
area is integrated in the rear trim.
Each 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.Center

!During parking maneuvers, pay special
attention to objects located above or
below the height of the sensors (e.g.
planters or trailer hitches). The Park-
tronic system will not detect such ob-
jects at close range and damage to
your vehicle or the object may result.
Ultrasonic signals from outside sourc-
es (e.g. truck air brakes or jackham-
mers) may impair the operation of the
Parktronic system.
