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

Minimum distance
approx. 8 in (20 cm)
Center
Corners approx. 6 in (15 cm)
If the system detects an obstacle in this
range, all the distance warning segments
illuminate and you hear a warning signal. If
the obstacle is closer than the minimum
distance, the actual distance may no long-
er 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 located in the rear
passenger compartment in the roof dome.
Front area warning indicator
1 Left side of the vehicle
2 Right side of the vehicle
3 Readiness indicators
Each warning indicator is divided into five
yellow and two red segments for either
side of the vehicle. The Parktronic system
is operational when the readiness
indicators 3 are illuminated.
The position of the automatic transmission
determines which warning indicator will be
activated.
