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 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 
will 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 t
o P (Park) or D 
(Drive).
 - The driver depr
esses the brake 
pedal with sufficient power
 - Braking assis
t has last for 
approximately 2 seconds
•	 The warning will turn off when:
 - The driver shifts the gear t
o 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 S
tability 
Control) warning light is on
 - ESC (Electronic S
tability 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.
OTM070079
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 
snow or rain, it may adversely affect 
sensor performance and Reverse Parking 
Collision-Avoidance Assist may not 
operate normally. Always keep the rear 
bumper clean.

 WARNING
Take the following precautions when 
using Reverse Parking Collision-
Avoidance Assist:
•	Always pay extreme caution while 
driving. The driver is responsible for 
controlling the brake for safe driving. 
•	 Always pay attention to road and 
traffic conditions while driving, 
whether or not there is a warning.
•	 Always look around your vehicle to 
make sure there are no pedestrians 
or objects before moving the vehicle.
•	 The performance of Reverse Parking 
Collision-Avoidance Assist may 
vary under certain conditions. If 
vehicle speed is above 2 mph (4 
km/h), the system will provide 
collision avoidance assist only when 
pedestrians are detected. Always 
look around and pay attention when 
backing up your vehicle.
•	 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.
•	 Reverse Parking Collision-Avoidance 
Assist may not operate properly 
or may operate unnecessarily 
depending on the road conditions 
and the surroundings.
•	 Do not solely rely on the system. 
Doing so may lead to vehicle damage 
or injuries.
 CAUTION
•	Noise may be heard when sudden 
braking occurs to avoid a collision. 
•	 If any other warning sound such 
as the seat belt warning chime is 
already generated, Reverse Parking 
Collision-Avoidance Assist warning 
may not sound. 
•	 The system may not work properly 
if the bumper has been damaged, 
replaced or repaired.
•	 Reverse Parking Collision-Avoidance 
Assist may not operate normally if 
interfered by strong electromagnetic 
waves.
•	 Playing the vehicle audio system at 
high volume may prevent passengers 
from hearing Reverse Parking 
Collision-Avoidance Assist warning 
sounds.
•	 Turn off Reverse Parking Collision-
Avoidance Assist when towing a 
trailer. If towing and moving in 
reverse, Reverse Parking Collision-
Avoidance Assist will activate as it 
detects the trailer.

 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.
•	 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.
•	 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.
•	 Never disassemble or strike the rear 
view camera or the rear ultrasonic 
sensors components.
•	 Do not strike or pry 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. We recommend that 
the vehicle be inspected by an 
authorized HYUNDAI dealer.
 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,

vehicle sensors to help the driver park 
and exit parking spaces remotely from 
outside the vehicle by controlling the 
steering wheel, vehicle speed and 
gearshifts.

 CAUTION
Take the following precautions to 
maintain optimal performance of the 
detecting sensors:
•	Never disassemble the detecting 
sensor or sensor assembly, or apply 
any impact on it.
•	 If the detecting sensor have been 
replaced or repaired, we recommend 
that you have your vehicle inspected 
by an authorized HYUNDAI dealer. 
•	 Remote Smart Parking Assist 
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.
