status. If the indicator blinks, have the vehicle inspected by an authorized
HYUNDAI dealer.

Non-Operational Conditions
of Forward/Reverse Parking
Distance Warning
Forward/Reverse Parking Distance
Warning 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
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 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.

Reverse Parking Collision-Avoidance
Assist is a supplemental function 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 function 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.
Reverse Parking Collision
Avoidance Assist Setting and
Operation
System setting
Parking Collision-Avoidance Assist-
Reverse 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 function 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 function 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 function deactivates when ‘Off’
is selected.
REVERSE PARKING COLLISION-AVOIDANCE ASSIST (PCA)

Operating conditions
Reverse Parking Collision-Avoidance
Assist enters the ready status, when
‘Active Assist’ or ‘Warning Only’ is
selected in the H/UNIT 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 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 y our vehicle and be aware of your
surroundings.
Warning and Control
Active assist

Convenience Features
5-98
The brake assist will turn off when:
• The driver shifts the gear to P (Park) or
D (Drive)
• The driver depresses the brake pedal
with sufficient power
• The braking has been assisted for
approximately 2 seconds
The warning will turn off when:
• The driver shifts the gear to P (Park), N
(Neutral), or D (Driv e)
The brake control may not operate
properly depending on the status of the
ESC (Electronic Stability Control). There
will only be a warning when:
• The ESC (Electronic Stability Control)
warning light is on
• The ESC (Electronic Stability Control)
is engaged in a different function
Warning only
• If Reverse Parking Collision Avoidance
Assist detects a risk of collision with
a pedestrian or an object, the system
will warn the driver with audible
warning and warnings on the cluster
LCD display or infotainment system
display.
• If ‘Warning Only’ is selected, braking
will not be assisted.
The warning will turn off when:
• The driver shifts the gear to P (Park), N
(Neutral), or D (Drive)
WARNING
• Reverse Parking Collision-Avoidance
Assist may not operate properly or
may operate unnecessarily in some
circumstances.
• Always pay extreme caution while
driving. The driver is responsible for
controlling the brake appropriately.
CAUTION
• Always pay attention to road and
traffic conditions while driving,
whether or not there is a warning.
• Playing the vehicle audio system at
high volume may prevent occupants
from hearing Reverse Parking
Collision-Avoidance Assist warning
sounds.
• If any other warning sound, such
as seat belt warning chime, is
already generated, Reverse Parking
Collision-Avoidance Assist warning
may not sound.
Information
Reverse Parking Collision Avoidance
Assist can detect a pedestrian or an object
when:
• A pedestrian is standing behind the
vehicle.
• A large obstacle, such as a vehicle, is
parked in the rear center of the vehicle.
