Minimum Distance; Range - Mercedes-Benz 2009 CLS-Class Operator's Manual

! Special attention must be paid to objects
with smooth surfaces or low silhouettes
(e.g. trailer couplings, painted posts, ele-
vated crossbars or road curbs). Such
objects may not be detected by the system
and can damage the vehicle.
During parking maneuvers, pay special
attention to objects located above or below
the height of the sensors (e.g. street curbs,
painted posts, or trailer hitches etc.). 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 sources
(e.g. truck air brakes, car wash, or jack-
hammers) may impair the operation of the
Parktronic system.

If the Parktronic system detects an obstacle
in this range, all the distance warning seg-
ments illuminate and you hear a warning sig-
nal. If the obstacle is closer than the minimum
distance, the actual distance may no longer
be indicated by the Parktronic system.
Warning indicators
Visual signals indicate to the driver the rela-
tive distance between the sensors and an
obstacle.
