Remote smart parking assist (RSPA)
(if equipped)
The Remote smart parking assist (RSPA)
system helps the drivers park their
vehicle by using sensors to measure
parking spaces and control the steering
wheel, gear shift and vehicle speed to
semi-automatically park the vehicle.
With the smart key, the driver can move
the vehicle forward or backward using
the rearward /forward buttons (5, 6) on
the smart key.
For information, refer to “Remote smart
parking assist (RSPA)” in this chapter.

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.
REVERSE PARKING COLLISION-AVOIDANCE ASSIST

Convenient Features5-90
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.

ODN8A059056ODN8A059056[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 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.

Types of warning sound and indicator
Types of warning sound Indicator
When an object is 24 in to 48 in (60 cm to 120 cm) from the rear
bumper : Buzz
er beeps intermittently.
When an object is 12 in to 24 in (30 cm to 60 cm) from the rear
bumper : Buzzer beeps more frequently.
When an object is within 12 in (30 cm) of the rear bumper :
Buzzer beeps continuously.
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.

Convenient Features5-98
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 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 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 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.
