WARNING
When using Smart Cruise Control take
the following precautions:
• If an emergency stop is necessary,
you must apply the brakes. The
vehicle cannot be stopped at every
emergency situation by using Smart
Cruise Control system.
• Keep a safe distance according to
road conditions and vehicle speed. If
the vehicle to vehicle distance is too
close during a high-speed driving, a
serious collision may result.
• Always maintain sufficient braking
distance and decelerate your vehicle
by applying the brakes if necessary.
• Smart Cruise Control system cannot
recognize a stopped vehicle,
pedestrians or an oncoming vehicle.
Always look ahead cautiously to
prevent unexpected and sudden
situations from occurring.
• Vehicles moving in front of you with
a frequent lane change may cause
a delay in the system's reaction or
may cause the system to react to a
vehicle actually in an adjacent lane.
Always drive cautiously to prevent
unexpected and sudden situations
from occurring.
• Always be aware of the selected
speed and vehicle to vehicle
distance. The driver should not solely
rely on the system but always pay
attention to driving conditions and
control your vehicle speed.
• Smart Cruise Control system may not
recognize complex driving situations
so always pay attention to driving
conditions and control your vehicle
speed.
• Smart Cruise Control system may
recognize a pedestrian, bicycle,
motorcycle, etc. as a vehicle. Always,
look ahead cautiously to prevent
unexpected and sudden situations
from occurring.
• Turn off Smart Cruise Control system
when the vehicle is being towed.
NOTICE

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.


Contr
olled 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.
Available highway

white.
ODN8A069214
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.
