The following objects may not be
recognized by the sensor:
• Sharp or slim objects such as
ropes, chains or small poles.
• Objects, which tend to absorb sen-
sor frequency such as clothes,
spongy material or snow.
WARNING
Your new vehicle warranty does
not cover any accidents or dam-
age to the vehicle or injuries to
its occupants related to a Rear
Parking Assist System. Always
drive safely and cautiously.
Rear parking assist system pre-
cautions
• The rear parking assist system may
not sound consistently depending on
the speed and shapes of the objects
detected.
• The rear parking assist system may
malfunction if the vehicle bumper
height or sensor installation has
been modified or damaged. Any
non-factory installed equipment or
accessories may also interfere with
the sensor performance.
• The sensor may not recognize
objects less than 30 cm (11 in.) from
the sensor, or it may sense an incor-
rect distance. Use caution.
• When the sensor is frozen or stained
with snow, dirt, or water, the sensor
may be inoperative until the stains
are removed using a soft cloth.
• Do not push, scratch or strike the
sensor with any hard objects that
could damage the surface of the
sensor. Sensor damage could occur.
• Do not spray the sensors or its sur-
rounding area directly with a high
pressure washer. Shock applied
from high pressure water may cause
the device to not operate normally.
