Precautions
• Forward/Reverse Parking Distance Warning system may not sound
consistently depending on the speed
and shapes of the objects detected.
• Forward/Reverse Parking Distance Warning 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 12 in (30 cm) from the
sensor, or it may sense an incorrect
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. Sensor damage could occur.
• Do not spray the sensors or its surrounding area directly with a high
pressure washer. Shock applied from
high pressure water may cause the
device to not operate normally.
