Range of the sensors
To function properly, the sensors must be
free of dirt, ice snow and slush. Clean the
sensors regularly, being careful not to
scratch or damage the sensors.
Front sensors
Center approx. 40 in (100 cm)
Corners approx. 48 in (120 cm)
Rear sensors
Center approx. 48 in (120 cm)
Corners approx. 32 in (80 cm)
!
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.
Controls in detail
Driving systems
Minimum distance
Center approx. 8 in (20 cm)
Corners approx. 6 in (15 cm)
If you encounter an obstacle in this range,
all the warning lamps light up and you hear
a warning signal. If the obstacle is closer
than the minimum distance, the actual dis-
tance may no longer be indicated by the
system.
Warning indicators
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.
