OJX1070028R
When you are driving forward out of a
parking space, if the function judges
that there is a collision risk with an
approaching vehicle in the blind spot,
the function will help avoid a collision by
applying the brake.
Information
In the following text, Blind-Spot Collision-
Avoidance Assist will be referred as
Blind-Spot Safety system.
Detecting sensor

Refer to the picture above for the
detailed location of the detecting
sensors.
CAUTION
Take the following precautions to
maintain optimal performance of the
detecting sensor:

[Never disassemble the rear corner
radar or radar assembly, or apply any
impact on it.

[If there is impact on the rear corner
radar or near the radar, even though
the warning message does not
appear on the cluster, Blind-Spot
Safety system may not operate
properly. We recommend that the
function be inspected by a HYUNDAI
authorised repairer.

[Changing lanes
OADAS030R
[A] : Your vehicle, [B] : Lane changing vehicle
When a vehicle moves into your lane
from an adjacent lane, it cannot be
detected by the sensor until it is in the
sensor's detection range. Smart Cruise
Control may not immediately detect
the vehicle when the vehicle changes
lanes abruptly. In this case, you must
maintain a safe braking distance, and
if necessary, depress the brake pedal
to reduce your driving speed in order
to maintain a safe distance.
[Detecting vehicle
OJX1070181R
In the following cases, some vehicles
in your lane cannot be detected by the
sensor:
- Vehicles offset to one side
- Slow-moving vehicles or sudden-
decelerating vehicles
- Oncoming vehicles
- Stopped vehicles
- Vehicles with small rear profile, such
as trailers
- Narrow vehicles, such as
motorcycles or bicycles
- Special vehicles
- Animals and pedestrians
Adjust your vehicle speed by
depressing the brake pedal according
to the road and driving conditions
ahead.

Driver assistance system

OBC3070011
In the following cases, the vehicle
in front cannot be detected by the
sensor:
- Vehicles with higher ground
clearance or vehicles carrying loads
that stick out of the back of the
vehicle
- Vehicles that has the front lifted due
to heavy loads
- You are steering your vehicle
- Driving on narrow or sharply curved
roads
Adjust your vehicle speed by
depressing the brake pedal according
to the road and driving conditions
ahead.

[When a vehicle ahead disappears
at an intersection, your vehicle may
accelerate.
Always pay attention to road and
driving conditions whilst driving.
OJX1070294R

[When a vehicle in front of you merges
out of the lane, Smart Cruise Control
may not immediately detect the new
vehicle that is now in front of you.
Always pay attention to road and
driving conditions whilst driving.

Rear Cross-Traffic Collision-
Avoidance Assist disabled
OTM070124L
When the rear bumper around the rear-
side radar or sensor is covered with
foreign material, such as snow or rain,
or installing a trailer or carrier, it can
reduce the detecting performance and
temporarily limit or disable Rear Cross-
Traffic Safety system.
If this occurs, the ‘Rear cross-traffic
VDIHW\IXQFWLRQVGLVDEOHG5DGDUEORFNHG
T
warning message will appear on the
cluster.
The function will operate normally when
such foreign material or trailer, etc. is
removed.
If the function does not operate normally
after it is removed, we recommend that
the function be inspected by a HYUNDAI
authorised repairer.
WARNING

[Even though the warning message
does not appear on the cluster, Rear
Cross-Traffic Safety system may not
operate properly.

[Rear Cross-Traffic Safety system may
not operate properly in an area (for
example: open terrain), where any
substance are not detected after
turning ON the engine.
CAUTION
Turn off Rear Cross-Traffic Safety
system to install a trailer, carrier, etc.,
or remove the trailer, carrier, etc. to use
Rear Cross-Traffic Safety system.
Limitations of Rear Cross-Traffic
Collision-Avoidance Assist
Rear Cross-Traffic Safety system may
not operate normally, or the function
may operate unexpectedly under the
following circumstances:

[Departing from where trees or grass
are overgrown

[Departing from where roads are wet

[Speed of the approaching vehicle is
fast or slow

attention is required in the following
circumstances:

[The vehicle severely vibrates whilst
driving over a bumpy road, uneven
road or concrete patch

[Driving on a slippery surface due to
snow, water puddle, ice, etc.

from the Settings menu, Reverse Parking
Collision-Avoidance Assist will be in
the ready status when the following
conditions are satisfied:
- The tailgate is closed
- The gear is shifted to R (Reverse)
- The vehicle is below 6 mph (10 km/h)
- Function components such as the rear
view camera and the rear ultrasonic
sensors are in normal conditions
When Reverse Parking Collision-
Avoidance Assist activates, a line
appears behind the vehicle image in the
instrument cluster.
Reverse Parking Collision-Avoidance
Assist operates only once after the gear
is shifted to R (Reverse). To reactivate
Reverse Parking Collision-Avoidance
Assist, shift the gear from another gear
to R (Reverse).

Active assist

[If the function detects a risk of
collision with a pedestrian or an
object, the function will warn the
driver with an audible warning,
steering wheel vibration (if equipped)
and warning message on the cluster.
When Rear View Monitor is operating,
a warning will appear on the
infotainment system screen.

[If the function detects an imminent
collision with a pedestrian or an object
behind the vehicle, the function 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 to P (Park) or D
(Drive).
- The driver depresses the brake pedal
with sufficient power
- Braking assist has last for
approximately 2 seconds

[The warning will turn off when:
- The driver shifts the gear to 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 Stability Control)
warning light is on
- ESC (Electronic Stability Control) is
engaged in a different function

WARNING
Take the following precautions when
using Reverse Parking Collision-
Avoidance Assist:

[Always pay extreme caution whilst
driving. The driver is responsible for
controlling the brake for safe driving.

[Always pay attention to road and
traffic conditions whilst 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
the vehicle speed is above 2 mph
(4 km/h), the function 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 function.
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 function 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.
