ODN8059057L
Push the button to turn off Reverse
Parking Distance Warning system. The
indicator light on the button will turn on.
Non-Operational Conditions
of Reverse Parking Distance
Warning System
Reverse Parking Distance Warning
system may not operate normally when: • Moisture is frozen to the sensor.
• Sensor is covered with foreign matter,
such as snow or water, or the sensor
cover is blocked.
There is a possibility of Reverse
Parking Distance Warning system
malfunction when: • Driving on uneven road surfaces such
as unpaved roads, gravel, bumps, or
gradient.
• Objects generating excessive
noise such as vehicle horns, loud
motorcycle engines, or truck air
brakes can interfere with the sensor.
• Heavy rain or water spray is present.
• Wireless transmitters or mobile
phones are present near the sensor.
• The sensor is covered with snow.
• Any non-factory equipment or
accessories have been installed, or if
the vehicle bumper height or sensor
installation has been modified.
Detecting range may decrease when: • Outside air temperature is extremely
hot or cold.

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 sensor
frequency such as clothes, spongy
material or snow.
• Undetectable objects smaller than 100
cm (40 in) and narrower than 14 cm (6
in) in diameter.
WARNING
Your new vehicle warranty does not
cover any accidents or damage to the
vehicle or injuries to its occupants
related to Reverse Parking Distance
Warning system. Always drive safely
and cautiously.
Reverse Parking Distance
Warning System Precautions
• Reverse Parking Distance Warning
system may not sound consistently depending on the speed and shapes
of the objects detected.
• 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 30 cm (12 in) 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 with any hard objects that
could damage the surface of 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.

Anti-lock Brake System (ABS)
WARNING
An Anti-Lock Braking System (ABS) or
an Electronic Stability Control (ESC)
system will not prevent accidents
due to improper or dangerous driving
maneuvers. Even though vehicle
control is improved during emergency
braking, always maintain a safe
distance between you and objects
ahead of you. Vehicle speeds should
always be reduced during extreme
road conditions. The braking distance
for cars equipped with ABS or ESC
may be longer than for those without
these systems in the following road
conditions.
Drive your vehicle at reduced speeds
during the following conditions: • Rough, gravel or snow-covered
roads.
• On roads where the road surface is
pitted or has different surface height.
The safety features of an ABS or ESC
equipped vehicle should not be tested
by high speed driving or cornering. This
could endanger the safety of yourself or
others.
ABS is an electronic braking system that
helps prevent a braking skid. ABS allows
the driver to steer and brake at the same time.
