WARNING
When Smart Cruise Control is
temporarily canceled, distance with the
front vehicle will not be maintained.
Always have your eyes on the road
while driving, and if necessary, depress
the brake pedal to reduce your driving
speed in order to maintain a safe
distance.
Smart Cruise Control conditions not
satisfied
OTM070112NOTM070112N
If the Driving Assist button, + switch,
- switch or switch is pushed
when Smart Cruise Control operating
conditions are not satisfied, the ‘Smart
Cruise Control conditions not met’ will
appear on the cluster, and an audible
warning will sound.
In traffic situation
OTM070114LOTM070114L
In traffic, your vehicle will stop if the
vehicle ahead of you stops. Also, if the
vehicle ahead of you starts moving, your
vehicle will start as well. In addition, after
the vehicle has stopped and a certain
time have passed, the ‘Use switch or
pedal to accelerate’ message will appear
on the cluster. Depress the accelerator
pedal or operate the + switch, - switch or
switch to start driving.
WARNING
While the message is displayed on the
cluster, if there is no vehicle in front or
the vehicle is far away from you, and the
+ switch, – switch or (Pause/Resume
) switch is operated, Smart Cruise
Control will automatically cancel and
EPB will be applied. However, if the
accelerator pedal is depressed, EPB
(Electronic Parking Brake) will not be
applied even though the function is
canceled. Always pay attention to the
road condition ahead.

On curves, Smart Cruise Control may
not detect a vehicle in the same lane,
and may accelerate to the set speed.
Also, vehicle speed may rapidly
decrease when the vehicle ahead is
detected suddenly.
Select the appropriate set speed on
curves and apply the brake pedal or
accelerator pedal according to the
road and driving conditions ahead.
OADAS015 OADAS015
Your vehicle speed can be reduced
due to a vehicle in the adjacent lane.
Apply the accelerator pedal and select
the appropriate set speed. Check
to be sure that the road conditions
permit safe operation of the Smart

Stopping vehicle and ending brake control
• When the vehicle is stopped due t
o emergency braking, the ‘Drive
carefully’ warning message will
appear on the cluster.
• For your safety, the driver should depress the brake pedal immediately
and check the surroundings.
• Brake control will end after the vehicle is stopped by emergency braking for
approximately 2 seconds.
• During emergency braking, braking control by Rear Cross-Traffic Collision-
Avoidance Assist will automatically
cancel when the driver excessively
depresses the brake pedal.
WARNING
Take the following precautions when
using Rear Cross-Traffic Collision-
Avoidance Assist :
• For your safety, only change the
Settings after parking the vehicle at a
safe location.
• If any other system’s warning
message is displayed or audible
warning is generated, Rear Cross-
Traffic Collision-Avoidance Assist
warning message may not be
displayed and audible warning may
not be generated.
• You may not hear the warning sound
of Rear Cross-Traffic Collision-
Avoidance Assist if the surroundings
are noisy.
• Rear Cross-Traffic Collision-
Avoidance Assist may not operate if
the driver applies the brake pedal to
avoid collision.
• During Rear Cross-Traffic Collision-
Avoidance Assist operation, the
vehicle may stop suddenly injuring
passengers and shifting loose
objects. Always have the seat belt on
and keep loose objects secured.
• Even if there is a problem with Rear
Cross-Traffic Collision-Avoidance
Assist, the vehicle’s basic braking
performance will operate normally.
• When Rear Cross-Traffic Collision-
Avoidance Assist is operating,
braking control by the function
will automatically cancel when the
driver excessively depresses the
accelerator pedal.
• Rear Cross-Traffic Collision-
Avoidance Assist does not operate
in all situations and cannot avoid all
collisions.

Rear Cross-Traffic Collision-
Avoidance Assist disabled
OTM070124NOTM070124N
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 Collision-Avoidance Assist.
If this occurs, the ‘Rear Cross-Traffic
Safety system disabled. Radar blocked’
warning message will appear on the
cluster.
Rear Cross-Traffic Collision-Avoidance
Assist will operate normally when
such foreign material or trailer, etc. is
removed.
If Rear Cross-Traffic Collision-Avoidance
Assist does not operate normally after it
is removed, have the vehicle inspected
by an authorized HYUNDAI dealer.
WARNING
• Even though the warning message
does not appear on the cluster, Rear
Cross-Traffic Collision-Avoidance
Assist may not operate properly.
• Rear Cross-Traffic Collision-
Avoidance Assist 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 Collision-
Avoidance Assist to install a trailer,
carrier, etc., or remove the trailer,
carrier, etc. to use Rear Cross-Traffic
Collision-Avoidance Assist.

WARNING
Take the following precautions when
using Reverse Parking Collision-
Avoidance Assist:
• Always exercise extreme caution
while driving. The driver is
responsible for braking and 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), Reverse Parking Collision-
Avoidance Assist 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 Reverse Parking
Collision-Avoidance Assist. 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.
• Reverse Parking Collision-Avoidance
Assist 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.
• 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
