Navigation-based Smart Cruise Control
system will help automatically adjust
your speed when a curved road is ahead
by receiving road information from
the navigation while the Smart Cruise
Control is operating.
WARNING
• Navigation-based Smart Cruise
Control system is not a substitute
for safe driving practices, but a
convenience function. It is the
responsibility of the driver to always
be aware of the surroundings and
drive safely.
• Navigation-based Smart Cruise
Control system relies entirely on
the road information provided by
the navigation system and may
accelerate above speed limit. It is the
responsibility of the driver to follow
traffic laws and avoid accidents.
• For your safety, please read the
owner's manual before using the
system.
Information
• Navigation-based Smart Cruise Control
system is available only on controlled
access road of certain highways.  Controlled access road indicates
roads with limited entrances and exits that allow uninterrupted high
speed traffic flow. Only passenger
cars and motorcycles are allowed on
controlled access roads.

System in operation
If the vehicle decelerates in a curve, the
symbol on the cluster will
illuminate green. • This system works only for curved
sections located on highway main lines.
• Depending on the curve ahead on the
road, the vehicle will decelerate, and
after passing curve, the vehicle will
accelerate to Smart Cruise Control set speed.
• The higher the driving speed, the
faster the vehicle is decelerated.
• The system responds to curves
located on the destination set in the
navigation. If the destination is not
set, the system will respond to road
information of the expected route.

Information
• Navigation-based Smart Cruise Control
is limited in other countries.
• The system may not operate due to the existence of leading vehicles and the driving situations of the vehicle.
• The system operates regardless of
whether the sharp curve warning appears on the navigation, but the time
gap could occur between the warning and system operation.
• The navigation only provides curve information within permitted speed ranges so that the system may not
decrease its speed during extreme over-speed driving.
• The system is not designed to work on
highways other than mentioned as a
controlled access road.
• The system automatically cancels when
you leave the highway. •
Highway Driving Assist and Navigation-based Smart Cruise
Control uses the same
symbol
that indicates the status of the system.
Therefore, even if Navigation-based
Cruise Control is off, the
symbol
may be displayed.
• If there is a problem with Navigation-
based Smart Cruise Control, the system
cannot be activated in the AVN system
screen, and the
symbol will turn
off. However, if Highway Driving Assist is activated, the
symbol will be
displayed.
• After you pass through a tollgate on a
highway, the system operates based
on the first lane. If you enter one of
the other lanes, the system might not
properly decelerate.
• If you over speed, the system may not decelerate the vehicle in a curve.
• Deceleration by the system may not be
sufficient if the driver accelerates while the system is operating,
• Deceleration by the system may not be
sufficient due to road conditions such
as uneven road surfaces, narrow lanes, etc.
• If the road is controlled, due to
construction or holiday events, the
system might not work properly.

or canceled by resetting the
navigation.
• The vehicle enters a service station
or rest area.
• A section of the highway’s shape has changed.
• Android Auto or Car Play is operating.
• The navigation cannot detect the

Lane Following Assist system helps
detect lane markers on the road
with a front view camera at the front
windshield, and assists the driver’s
steering to help keep the vehicle
between lanes.
WARNING
Lane Following Assist system is not a
substitute for safe driving practices,
but a convenience function. It is the
responsibility of the driver to always be
aware of the surroundings and steer the
vehicle.
WARNING
Take the following precautions when
using Lane Following Assist system: • Do not turn the steering wheel
suddenly when the steering wheel is
being assisted by the system.
• LFA system helps the driver to keep
the vehicle in the center of the lane
by assisting the driver’s steering.
However, the driver should not solely
rely on the system but always pay
attention on the steering wheel to
stay in the lane.
• The operation of LFA system can
be canceled or not work properly
according to road condition and
surroundings. Always be cautious when driving.
• Do not disassemble LFA system
camera temporarily to tint the
window or attach any types of
coatings and accessories. If you
disassemble the camera and
assemble it again, have the vehicle
inspected by an authorized HYUNDAI
dealer.
• When you replace the windshield
glass, LFA system camera or related
parts of the steering wheel, have the
vehicle inspected by an authorized
HYUNDAI dealer.
• The system helps detect lane
markers and controls the steering
wheel by a camera, therefore, if the
lane markers are hard to detect, the
system may not work properly.
• Please refer to “Limitations of the
S y s t e m ”.
• Do not remove or damage the related
parts of LFA system.
• You may not hear a warning sound
of LFA system if the audio volume is high.

•
Do not place objects on the
dashboard that reflects light such as
mirrors, white paper, etc. This may
prevent LFA system from functioning
properly.
• Always have your hands on the
steering wheel while LFA system is
activated. If you continue to drive
with your hands off the steering
wheel after the “Keep hands on
steering wheel” warning message
appears, the system will turn off
automatically.
However, if the driver has their
hands on the steering wheel again,
the system will start controlling the
steering wheel.
• The steering wheel is not
continuously controlled so if the
vehicle speed is at a higher rate
when leaving a lane the vehicle may
not be controlled by the system. The
driver must always follow the speed
limit when using the system.
• If you attach objects to the steering
wheel, the system may not assist
steering or the hands off alarm may
not work properly.
