122 Driving and operating
■ An object was hanging out of the
tailgate during the last drive cycle.
Once the object is removed,
ultrasonic parking assist will return
to normal operation.
■ An object or cover is attached to the
front of the vehicle.
■ The bumper is damaged. Take the
vehicle to a workshop to repair the
system.
■ Other conditions, such as
vibrations from a jackhammer or
the compression of air brakes on
a very large truck, are affecting
system performance.
Should the system still do not work
properly, seek the assistance of
a workshop.

Important hints for using the
ultrasonic parking assist
systems
9 Warning
Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external noise sources may cause
the system to fail to detect
obstacles.
Special attention has to be paid to
low obstacles which can damage
the lower part of the bumper. If
such obstacles leave the detection
area of the sensors during
approach of the vehicle,
a continuous warning tone will
sound.
Caution
Performance of the ultrasonic
parking assist systems can be
reduced due to heavy loading.
Special conditions apply if there
are taller vehicles involved (e.g.
off-road vehicles, mini vans,
vans). Object identification in the
upper part of these vehicles
cannot be guaranteed.
Objects with a very small reflection
cross section, like objects of
narrow size or soft materials, may
not be detected by the system.
Ultrasonic parking assist will not
avoid a collision with objects which
are out of the detection range of
the sensors.
