Non-Operational Conditions
of Forward/Reverse Parking
Distance Warning System
Forward/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 Forward/
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 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
vehicle or injuries to its occupants
related to Forward/Reverse Parking
Distance Warning system. Always drive
safely and cautiously.

Forward/Reverse Parking
Distance Warning System
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.

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.

Check Blind-Spot Collision-Avoidance
Assist (BCA) system
If there is a problem with BCA system,
a w
arning message will appear. The
system will turn off automatically. BCW
will still operate even if BCA system turns
off due to malfunction. Have the vehicle
inspected by an authorized HYUNDAI
dealer.
Limitations of the System
The driver must be cautious in the below
situations, because the system may not
detect other vehicles or objects in certain
circumstances.
• The system may not work around 15 seconds after starting the vehicle or
the initialization or rebooting of the
front view camera.
• When a trailer or carrier is installed.
• The vehicle drives in inclement weather such as heavy rain or snow.
• The sensors are polluted with rain, snow, mud, etc.
• The rear bumper where the sensors are located is covered with a foreign
object such as a bumper sticker, a
bumper guard, a bike rack, etc.
• The rear bumper is damaged, or the sensor is out of the original default
position.
• The vehicle height gets lower or higher due to heavy loading in a trunk,
abnormal tire pressure, etc.
• When the temperature of the rear bumper is high.
• When the sensors are blocked by other vehicles, walls or parking-lot
pillars.
• The vehicle drives on a curved road.
• The vehicle drives through a tollgate.
• The road pavement (or the peripheral ground) abnormally contains metallic
components (i.e. possibly due to
subway construction).
• There is a fixed object near the vehicle, such as a guardrail.

• 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.

[A] : Noise barrier, [B] : Guardrail
• 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.

• Your vehicle may accelerate when a vehicle ahead of you disappears.
• When you are warned that the vehicle ahead of you is not detected, drive
with caution.
ODN8A069222ODN8A069222
• When driving in stop-and-go traffic, and a vehicle in front of you merges
out of the lane, the system may not
immediately detect the new vehicle
that is now in front of you. In this case,
you must maintain a safe braking
distance, and if necessary, depress
the brake pedal to reduce your driving
speed in order to maintain a safe
distance.
