To Turn off Reverse Parking
Distance Warning System
(if equipped)
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

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.

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 40
in (100 cm) and narrower than 6 in (14
cm) in diameter.
WARNING
Your new vehicle warranty does not
cover any accidents or damage to the

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 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 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.
• Tire chains are installed on your
vehicle.
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.

bumper is high.
• When the sensors are blocked by
other vehicles, walls or parking-lot

• Driving where the heights of the lanes
are different
BCW and BCA systems may not
operate properly when driving where
the heights of the lanes are different.
In certain instances, the system may
not detect the vehicle on a road with
different lane heights (i.e. underpass
joining section, grade separated
intersections, etc.).
Always pay attention to road and
driving conditions, while driving.

• Driving where there is a structure
beside the road
BCW and BCA systems may not
operate properly when driving where
there is structure beside the road.
In certain instances, the system may
wrongly recognize the structures
(i.e. noise barriers, guardrail, double
guardrail, median strip, bollard, street
light, road sign, tunnel wall, etc.)
beside the road.
Always pay attention to road and
driving conditions, while driving.
