NOTE
•
The system will not detect high objects,
such as a loading dock, etc.
•
Certain materials or fabrics may not be
detected by the sensors. Objects made of
these materials or people wearing cloth-
ing made of these fabrics may not be
detected.
•
Children or animals near the vehicle may
not always be detected.
•
Objects such as chains, thin shiny poles
or low objects may temporarily not be
detected by the system. This may result
in the pulsing tone unexpectedly stopping
instead of changing to a constant tone as
the vehicle approaches the object. In
such cases, use caution when backing up
or stop the vehicle to help avoid damage.
•
In certain circumstances, the park assist
system may give unexpected warning sig-
nals that can be caused by external
sound sources that use the same ultra-
sound frequencies as the system. This
may include such things as the horns of
other vehicles, wet tires on asphalt, pneu-
matic brakes, motorcycle exhaust pipes,
other vehicles with similar ultrasound sys-
tems, etc. This does not indicate a fault in
the system.

Cleaning the sensors
Location of the Park Assist sensors
The sensors must be cleaned regularly to ensure
that they work properly. Clean them with water
and a suitable car washing detergent.
NOTE
If the sensors are obstructed by e.g., dirt,
snow, or ice, this could result in false warning
signals from the park assist system or the
system may not function at all.
