Reverse Parking Collision-Avoidance
Assist (PCA) is a supplemental system
that can warn the driver or apply braking
force to reduce the possibility of collision
with pedestrians when the vehicle is
reversing.
WARNING
• Always look around your vehicle to
make sure there are no objects or
pedestrian before moving the vehicle
in any direction to prevent a collision.
• Do not solely rely on Reverse Parking
Collision-Avoidance Assist system.
The system might not assist the
driver leading to pedestrian injury or
vehicle damage.
• Be aware that some objects may
not be visible on the screen or be
detected by the rear ultrasonic
sensors, due to the objects’ distance,
size or material, all of which can limit
the effectiveness of the sensors.
System Setting and Operation
System setting
Parking Collision-Avoidance Assist-
Reverse (PCA-R) can be activated from
the Settings menu in the LCD display or
infotainment system display by following
the procedure below.
1. Set the Engine Start/Stop button to
the ON or START position.
2. Select ‘User Settings → Driver Assistance → Parking Safety → Active
Assist / Warning Only / Off’ in the
LCD display or infotainment system
display.
- The system is ready for operation when ‘Active Assist’ is selected. In
the event of an imminent collision
with a pedestrian or an object, the
system warns the driver or applies
braking force to help avoid the
collision.
- The system is ready for operation when ‘Warning Only’ is selected. In
the event of an imminent collision
with a pedestrian, the system warns
the driver but does not assist in
braking.
- The system deactivates when ‘Off’ is selected.

Operating conditions
Reverse Parking Collision-Avoidance
Assist system enters the ready status,
when ‘Active Assist’ or ‘Warning Only’ is
selected in the AVN system screen and
the following conditions are satisfied:
• The trunk is closed
• The shift lever is in R (Reverse)
• Vehicle speed is below 6 mph (10 km/h)
• System components such as the rear view camera and the rear ultrasonic
sensors are in normal conditions
The driver needs to select ‘Active Assist’
on the LCD display or infotainment
system display for collision-avoidance
assist.
The solid lines behind the vehicle in the
cluster LCD display indicates that the
system is ready to assist the driver.
Note that the system assists the driver
only once. The driver has to shift the gear
to R (Reverse) from another gear position
to reactivate the system.
The performance of Reverse Parking
Collision-Avoidance Assist system may
vary under certain conditions. If the
vehicle speed exceeds 2 mph (3 km/h),
the system can assist only pedestrian
collision avoidance.
As always, be careful when backing
up your vehicle and be aware of your
surroundings.

the vehicle, the system will warn the
driver with audible warning, steering
wheel vibration, and warnings on
the cluster LCD display and the
infotainment system display.
• If the system detects imminent collision with a pedestrian or an object
behind the vehicle, the system may
apply braking power. The driver needs
to pay attention as the brake will
release within 2 seconds. The driver
must immediately depress the brake
pedal and check surroundings.

ODN8A059303ODN8A059303Rear view camera
The rear view camera acquires images
f
or 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 sensor
s 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.

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 48
in (120 cm) 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 3 mph (5 km/h), the
system may not detect objects.
• If vehicle speed exceeds 6 mph (10 km/h), 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.
