FORWARD/REVERSE PARKING DISTANCE WARNING (PDW)
Forward/Reverse Parking Distance
Warning will help warn the driver if an
obstacle is detected when the vehicle
is moving forward or in reverse at low
speeds.
WARNING
• Forward/Reverse Parking Distance
Warning is a supplemental system.
The operation of the system can be
affected by several factors (including
environmental conditions). It is the
responsibility of the driver to always
check the front and rear views before
and while parking.
• Pay close attention when driving
near objects, pedestrians, and
especially children.
Some objects may not be detected
by the ultrasonic sensors, due to the
objects distance, size or material, all
of which can limit the effectiveness
of the sensor.
• Your new vehicle warranty does not
cover any accidents or damage to
the vehicle caused by the driver.

CAUTION
Take the following precautions to
maintain optimal performance of the
detecting sensor:
• Never disassemble the detecting
sensor or sensor assembly, or apply
any impact on it.
• If the detecting sensors have been
replaced or repaired, have your
vehicle inspected by an authorized
retailer of Genesis Branded products.
• Forward/Reverse Parking Distance
Warning may not operate normally
when:
-Moisture is frozen to the sensor
-Sensor is covered with foreign
material, such as snow or water
(The system will operate normally
when such foreign material are
removed.)
• Forward/Reverse Parking Distance
Warning may malfunction when:
-Driving on uneven road, gravel
roads or bushes
-Objects that generates ultrasonic
waves such as vehicle horns, loud
motorcycle engine sound or truck
air brakes are near 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
-Affected by another vehicle’s
sensors
-Water flows on the surface of the
sensor
-Installing the license plate
differently from the original
location
• Detecting range may decrease when:
-Sensor is covered with foreign
material, such as snow or water
(The system will operate normally
when such foreign material are
removed.)
-The weather is extremely hot or
cold
• The following objects may not be
detected:
-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.
-Objects smaller than 40 in. (100
cm) in length and narrower than
6 in. (14 cm) in diameter.

• The corresponding indicator will illuminate whenever each ultrasonic senor detects
a object in its sensing range.
• Only the front sensors warn the driver when moving forward. The rear and front-
side sensors warn the driver when moving in reverse. However, the object must be
within 24 in. (60 cm) from the front-side sensors to operate.
• If an object is within 12 in. (30 cm) from the ultrasonic sensors, the sensors may not
detect the object, or a sensor out of the detecting range may warn the driver.
• Distance warning may not occur sequentially depending on vehicle speed or
obstacle shape.
• Indicators and warning sounds may differ from the illustration when obstacles are
located in the center of the sensor, obstacles are located in close proximity to the
vehicle, or in various circumstances.
• The shape of the indicator in the illustration may differ from the actual vehicle.

System Malfunction and
Precautions
System malfunction
Forward/Reverse Parking Distance
Warning has a self-diagnosis function
that can determine whether the
ultrasonic sensor is working properly.
After starting the engine, a beep will
sound when the gear is shifted to R
(Reverse) to indicate the system is
operating normally.
However, if one or more of the following
occurs, first check whether the ultrasonic
senior is damaged or whether the system
is in a non-operating condition. If it still
does not work properly, have the system
inspected by an authorized retailer of
Genesis products.
• The audible warning does not sound.
• The buzzer sounds intermittently.
• The ‘Parking sensor error or blockage’
warning message appears on the
cluster.
OJX1079125LOJX1079125L
System precautions
• Forward/Reverse Parking Distance
Warning may malfunction if the
vehicle bumper height or ultrasonic
sensor installation has been modified
or damaged. Any non-factory installed
equipment or accessories may also
interfere with the sensor performance.
• When the ultrasonic sensor is frozen
or stained with snow, dirt, or water,
the sensor may be not operate until
the stains are removed using a soft
cloth.
• Do not push, scratch or strike the
ultrasonic sensor. Sensor damage
could occur.
• Do not spray the ultrasonic sensors
or its surrounding area directly with a
high pressure washer.

Reverse Parking Collision-Avoidance
Assist may warn the driver or may
assist with braking to help reduce the
possibility of collision with a pedestrian
or an object when backing up.
WARNING
• ALWAYS look around your vehicle to
make sure there are no pedestrians
or objects before moving the vehicle.
• Do not solely rely on the system.
Doing so may lead to vehicle damage
or injuries.
• Some objects may not be detected
by the rear ultrasonic sensors due
to the objects distance, size or
material, all of which can limit the
effectiveness of the sensor.

CAUTION
Take the following precautions to
maintain optimal performance of the
detecting sensors:
• Always keep the rear view camera
and rear ultrasonic sensors clean.
• Do not use any cleanser containing
acid or alkaline detergents when
cleaning the rear view camera lens.
Use only a mild soap or neutral
detergent, and rinse thoroughly with
water.
• Never disassemble or apply impact
on the rear view camera or the rear
ultrasonic sensors components.
• Do not apply unnecessary force on
the rear view camera or the rear
ultrasonic sensors. The system may
not operate properly if the rear
view camera or the rear ultrasonic
sensor(s) is forcibly moved out of
proper alignment. Have the vehicle
inspected by an authorized retailer of
Genesis Branded products.
• Do not spray the rear view camera or
the rear ultrasonic sensors or their
surrounding area directly with a
high pressure washer. It may cause
the rear view camera or the rear
ultrasonic sensors to malfunction.
• The system may not work properly
if the bumper has been damaged,
replaced or repaired.
• Do not apply objects, such as a
bumper sticker or a bumper guard,
near the rear view camera or rear
ultrasonic sensors or apply paint to
the bumper. Doing so may adversely
affect the performance of the
system.
• Reverse Parking Collision-Avoidance
Assist may not operate normally if
interfered by strong electromagnetic
waves.

km/h)
-System components such as the rear
view camera and the rear ultrasonic
sensors are in normal conditions
Rear Warning Only
• If the system detects a risk of collision
with a pedestrian or an object, the
system will warn the driver with an
audible warning, steering wheel
vibration and warning message on
the cluster. When Rear View Monitor
is operating, a warning will appear on
the infotainment system screen.
• ‘If ‘Rear Warning Only’ is selected,
braking will not be assisted.
• The warning will turn off when the
gear is shifted to P (Park), N (Neutral)
or D (Drive). Rear Active Assist
• If the system detects a risk of collision
with a pedestrian or an object, the
system will warn the driver with an
audible warning, steering wheel
vibration and warning message on
the cluster. When Rear View Monitor
is operating, a warning will appear on
the infotainment system screen.
• If the system detects an imminent
collision with a pedestrian or an
object behind the vehicle, the system
may assist you with braking. The
driver needs to pay attention as the
brake assist will end within 2 seconds.
The driver must immediately depress
the brake pedal and check vehicle
surroundings.
• Brake control will end when:
-
The gear is shifted to P (Park) or D
(Drive).
-The driver depresses the brake
pedal with sufficient power
-Braking assist last for approximately
2 seconds
• The warning will turn off when:
-The driver shifts the gear to P (Park),
N (Neutral), or D (Drive)
• The brake control may not operate
properly depending on the status of
ESC (Electronic Stability Control).
There will only be a warning when:
-The ESC (Electronic Stability
Control) warning light is on
-ESC (Electronic Stability Control) is
engaged in a different function

The rear view camera is used as a
detecting sensor to detect pedestrians. If
the camera lens is covered with foreign
material, such as snow or rain, it may
adversely affect camera performance
and Reverse Parking Collision-Avoidance
Assist may not operate normally. Always
keep the camera lens clean.
OJX1079171L OJX1079171L
The rear ultrasonic sensors are located
inside the rear bumper to detect objects
in the rear area. If the sensors are
covered with foreign material, such as
