Rear view camera
The rear view camera acquires images
for rear pedestrian detection. If the
camera lens is covered with snow, rain,
or a foreign substance, the system may
not work properly. Always keep the
camera lens clean.
Rear ultrasonic sensors
The rear ultrasonic sensors detect
objects. The sensors are installed in
the rear bumper. If the rear ultrasonic
sensor(s) is covered with snow, rain, or
a foreign substance, the system may
not work properly. Always keep the rear bumper clean.
NOTICE
•
The system may turn off if interfered
by electromagnetic waves.
• Always keep the rear view camera
and the 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 the rear view
camera or the ultrasonic sensor
components or apply any impact
on the rear view camera or the
ultrasonic sensor components.
• Do not apply unnecessary force
on the rear view camera or the
ultrasonic sensors. The system
may not operate properly if the
rear view camera or the ultrasonic
sensor(s) is forcibly moved out of
proper alignment. Have the vehicle
inspected by an authorized HYUNDAI
dealer.
• Do not spray the rear view camera
or the ultrasonic sensors or their
surrounding area directly with a high
pressure washer. Shock applied from
high pressure water may cause the
device to malfunction.
• The system may not work properly if the bumper has been damaged, or if
the rear bumper has been replaced
or repaired.
• Do not apply foreign objects, such as
a bumper sticker or a bumper guard,
near the camera or sensors or apply
paint to the bumper. Doing so may
adversely affect the performance of
the system.

[A] : Rear Sensor
Reverse Parking Distance Warning
system assists the driver during reverse
movement of the vehicle by chiming if
an object is sensed within the distance of
120 cm (48 in) behind the vehicle.
This system is a supplemental system
that senses objects within the range and
location of the sensors, it cannot detect
objects in other areas where sensors are
not installed.
WARNING
• ALWAYS look around your vehicle to
make sure there are not any objects
or obstacles before moving the
vehicle in any direction to prevent a
collision.
• Always pay close attention when the
vehicle is driven close to objects,
particularly pedestrians, and
especially children.
• Be aware that some objects may
not be visible on the screen or be
detected by the sensors, due to the
objects distance, size or material, all
of which can limit the effectiveness
of the sensor.
Operation of Reverse Parking
Distance Warning System
Operating condition • This system will activate when
backing up with the ignition switch in
the ON position. However, if vehicle
speed exceeds 5 km/h (3 mph), the
system may not detect objects.
• If vehicle speed exceeds 10km/h (6
mph), the system will not warn you
even though objects are detected.
• When more than two objects are
sensed at the same time, the closest
one will be recognized first.

bumper : Buzzer beeps intermittently.
When an object is 30 cm to 60 cm (12 in to 24 in) from the rear
bumper : Buzzer beeps more frequently.
When an object is within 30 cm (12 in) of the rear bumper :

NOTICE
• The indicator may differ from the illustration depending on objects or sensors
status. If the indicator blinks, have the vehicle inspected by an authorized
HYUNDAI dealer.
• If the audible warning does not sound or if the buzzer sounds intermittently when
shifting into R (Reverse) position, this may indicate a malfunction with Reverse
Parking Distance Warning system. If this occurs, have the vehicle inspected by an
authorized HYUNDAI dealer.

• 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 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.
