the vehicle ahead
Smart Cruise Control uses a sensor
to detect distance to the vehicleahead.
If the sensor is covered with dirt or
other foreign matter, the vehicle to
vehicle distance control may not
operate correctly. Always keep thesensor clean.
Warning message
Smart Cruise Control disabled.
Radar blocked
When the sensor lens cover is
blocked with dirt, snow, or debris,
Smart Cruise Control system opera-

Check Smart Cruise Control
System
The message will appear when the
vehicle to vehicle distance control
system is not functioning normally.
We recommend that you take your
vehicle to an authorized HYUNDAI
dealer and have the system checked.
i
Do not apply license plate
frame or foreign objects such
as a bumper sticker or a
bumper guard near the radar
sensor. Doing so may
adversely affect the sensing
performance of the radar.
Always keep the radar sensor
and lens cover clean and free
of dirt and debris.
Use only a soft cloth to wash
the vehicle. Do not spray pres-
surized water directly on the
sensor or sensor cover. (Continued)
CAUTION
(Continued)
Be careful not to apply unnec-
essary force on the radar sen-
sor or sensor cover. If the sen-
sor is forcibly moved out of
proper alignment, the Smart
Cruise Control system may
not operate correctly. In this
case, a warning message may
not be displayed. Have the
vehicle inspected by an
authorized HYUNDAI dealer.
If the front bumper becomes
damaged in the area around
the radar sensor, Smart
Cruise Control system may
not operate properly. We rec-
ommend you to have the vehi-
cle inspected by an author-
ized HYUNDAI dealer.
Use only genuine HYUNDAI
parts to repair or replace a
damaged sensor or sensor
cover. Do not apply paint to
the sensor cover.

On inclines
During uphill or downhill driving,Smart Cruise Control system may
not detect a moving vehicle in your
lane, and cause your vehicle to
accelerate to the set speed. Also,
the vehicle speed will rapidly
decrease when the vehicle ahead
is recognized suddenly.
Select the appropriate set speed on inclines and apply the brake or
accelerator pedal if necessary.
Lane changing
A vehicle which moves into yourlane from an adjacent lane cannot
be recognized by the sensor until it
is in the sensor's detection range.
The radar may not detect immedi- ately when a vehicle cuts in sud-
denly. Always pay attention to the
traffic, road and driving conditions.
If a slower vehicle moves into your lane, your speed may decrease to
maintain the distance to the vehicleahead.
If a faster vehicle which moves into your lane, your vehicle will acceler-ate to the set speed.
Vehicle recognition
Some vehicles in your lane cannot
be recognized by the sensor:
- Vehicles offset to one side
- Slow-moving vehicles or sudden-decelerating vehicles
- Stopped vehicles
- Vehicles with small rear profile such as trailers with no loads

Driving your vehicle
A vehicle ahead cannot be recog-
nized correctly by the sensor if any of
following occurs:
- When the vehicle is pointingupwards due to overloading in the
luggage compartment
- While the steering wheel is operat- ing
- When driving to one side of the lane
- When driving on narrow lanes or on curves
Apply the brake or accelerator pedal
if necessary. Your vehicle may accelerate when
a vehicle ahead of you disappears.
When you are warned that the vehicle ahead of you is not detect-
ed, drive with caution. When driving in stop-and-go traffic,
and a vehicle in front of you
merges out of the lane, the system
may not immediately detect the
new vehicle that is now in front of
you. In this case, you must main-
tain a safe braking distance, and if
necessary, depress the brake
pedal to reduce your driving speed
in order to maintain a safe dis-
tance.
OAD058174NOAD058168L
Smart Cruise Control is basical-
ly designed to set vehicles as a
target. Always look ahead cau-
tiously to cope with unexpected
situations such as a collisionwhen the system sets an object
as a target, not vehicles.
WARNING

Driving your vehicle
The lane marker is very thick orthin.
The lane is very wide or narrow.
The lane marker ahead is not visi- ble due to rain, snow, water on the road, damaged or stained road
surface, or other factors.
The shadow is on the lane marker by a median strip, trees, guardrail,
noise barriers, etc.
The lane markers are complicated or a structure substitutes for the
lines such as a construction area.
There are crosswalk signs or other symbols on the road.
The lane marker in a tunnel is stained with oil, etc.
The lane suddenly disappears such as at the intersection. When external condition is inter-vened
The brightness outside changes
suddenly such as when entering or
exiting a tunnel, or when passing
under a bridge.
The brightness outside is too low such as when the headlamps are
not on at night or the vehicle isgoing through a tunnel.
There is a boundary structure in the roadway such as a concrete
barrier, guardrail and reflector post
that is inadvertently being detected
by the camera.
When light coming from a street light or an oncoming vehicle is
reflected on a wet road surfacesuch as a puddle in the road.
The field of view in front is obstructed by sun glare.
There is not enough distance between you and the vehicle in
front to be able to detect the lane
marker or the vehicle ahead is driv-
ing on the lane marker. Driving on a steep grade, over a
hill, or when driving on a curvedroad.
The adverse road conditions cause excessive vehicle vibrations while
driving.
The surrounding of the inside rear view mirror temperature is highdue to direct sunlight, etc.
When front visibility is poor
The windshield or the camera lens is blocked with dirt or debris.
The windshield glass is fogged up; a clear view of the road is obstruct- ed.
Placing objects on the dashboard, etc.
The sensor cannot detect the lane because of fog, heavy rain or snow.

Detecting Sensor
The rear radars are located inside
the rear bumper for detecting the
side and rear. Always keep the rear
bumper clean for proper operation ofthe system. The system may not work prop-
erly when the bumper has been
damaged, or if the rear bumperhas been replaced or repaired.
The system may turn off if inter- fered by strong electromagnetic
waves.
Always keep the sensors clean.
NEVER disassemble the sensor component or apply any impact on the sensor component.
Be careful not to apply unneces- sary force on the radar sensor or
sensor cover. If the sensor is
forcibly moved out of proper
alignment, the system may not
operate correctly. In this case, a
warning message may not be dis-
played. We recommend that you
have the vehicle inspected by an
authorized HYUNDAI dealer.
