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

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.

cluster if the following situations occur:
- The rear vie

w camera is covered with
foreign material, such as snow or rain,
etc.
- There is inclemen

t weather, such as

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.

Driver assistance system
7-122
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.
