Auto defogging system (if equipped)
Auto defogging reduces the probability of
fogging up the inside of the windshield byautomatically sensing the moisture ofinside the windshield.This indicator illuminates
when the auto defoggingsystem senses the moistureof inside the windshield and
operates.
If more moisture is in the vehicle, the
higher steps operate as follow. For exam-
ple if auto defogging does not defoginside the windshield at step 1 Outside
air position, it tries to defog again at step
2 Blowing air toward the windshield.
Step 1 : Outside air positionStep 2 :Blowing air toward the windshield
Step 3 : Increasing air flow toward the windshield
Step 4 : Operating the air conditioning
Step 5 : Maximizing the air conditioning
✽✽ NOTICE
 If the A/C off or recirculated air posi- tion is manually selected while the
auto defogging system is on, the auto
defogging indicator will blink 3 times
to give notice that manual operation is
canceled.
 If the air quality system (AQS) is
selected while the auto defogging sys-
tem is operating at the step 1 outside
air position, the recirculated air posi-
tion may operate when the outside air
is polluted.

CAUTION
Do not remove the sensor cover
located on the upper end of the pas- senger side windshield glass.Damage to system parts could occur and may not be covered by

Driving your vehicle
Decreasing the vehicle speed to lessthan approximately 10km/h (6.2mph)
as the vehicle in front of you.
Accelerating the vehicle speed to more than approximately 180km/h(113mph).
The ESP is turned off.
The sensor or the cover is stained with foreign matter.
Each of these actions will cancel smart
cruise control operation (the SET indica-
tor light, set speed and vehicle to vehicledistance on the LCD screen will go out),but it will not turn the system off. If youwish to resume smart cruise control
operation, push the RES+ switch locatedon your steering wheel. You will return toyour previously preset speed.
To resume cruising speed at
more than approximately 10 km/h(6.2 mph):
If any method other than the cruise
ON/OFF switch was used to cancel cruis-
ing speed and the system is still activat-ed, the most recent set speed will auto-
matically resume when the RES+ switchis pushed.
It will not resume, however, if the vehicle
speed has dropped below approximately10 km/h (6.2 mph) when the sensor
detects the vehicle ahead or if the vehicle
speed has dropped below approximately30 km/h (18.6 mph) when there is no
vehicle in front of your vehicle.
✽✽ NOTICE
Always check the road conditions when
pressing the RES+ switch to resume the
speed.
To turn cruise control off, do one
of the following:
Push the cruise ON/OFF button (the CRUISE indicator light in the instru- ment cluster will go out).
Turn the engine off.
Both of these actions cancel smart cruise control operation. If you want to resume smart cruise control operation, repeat
the steps provided in “To set cruise con- trol speed” on the previous page.OVI059030
CAUTION
If the sensor cover is dirty orobstructed, the smart cruise control
operation will cancel automatically.

Sensor to detect distance to the
vehicle ahead
The sensor detects distance to the vehi- cle ahead.
If the sensor is covered with dirt or other
foreign matter, the vehicle to vehicle dis-
tance control may not operate correctly.
Always keep the sensor clean.Sensor malfunction indicator
If the sensor or cover is dirty or obscured
with foreign matter such as snow, the
indicator will illuminate. Clean the sensor
by using a soft cloth.
SCC (Smart cruise control) malfunc-
tion indicator
The warning light illuminates when the
vehicle to vehicle distance control sys-
tem is not functioning normally.
Take your vehicle to an authorized
HYUNDAI dealer and have the system
checked.

Limitations of the system
The smart cruise control system may
have limits to its ability to detect distance
to the vehicle ahead due to road and traf-
fic conditions.
On curves
On curves, the smart cruise controlsystem may not detect a moving vehi-
cle in your lane, and then your vehicle
could accelerate to the set speed. Also,
the vehicle speed will slow down when
the vehicle ahead is recognized sud-
denly.
Select the appropriate set speed on curves and apply the brakes or accel-
erator pedal if necessary. 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 cruise con-trol.
OBH058030OBH058029
CAUTION
Do not install accessories around
the sensor and do not replace the
bumper by yourself. It may inter-fere with the sensor performance.
Always keep the sensor and bumper clean.
To prevent sensor cover damage from occurring, wash the car witha soft cloth.
Do not damage the sensor or sen- sor area by a strong impact. If thesensor moves slightly off posi-
tion, the smart cruise control sys-tem will not operate correctly.
If this occurs, have your vehiclechecked by an authorizedHYUNDAI dealer as soon as pos-
sible.
Use only a genuine HYUNDAI sensor cover for your vehicle.

On inclines
During uphill or downhill driving, the
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 slow down when the vehicle ahead
is recognized suddenly.
Select the appropriate set speed on inclines and apply the brakes or accel-
erator pedal if necessary.
Lane changing
A vehicle which moves into your lanefrom an adjacent lane cannot be rec-
ognized by the sensor until it is in the
sensor's detection range.
The sensor may not detect immediate- ly when a vehicle cuts in suddenly.
Always pay attention to the traffic, road
and driving conditions.
If a vehicle which moves into your lane is slower than your vehicle, your speed
may decrease to maintain the distance
to the vehicle ahead.
If a vehicle which moves into your lane is faster than your vehicle, your vehicle
will accelerate to the selected speed.
Vehicle recognition
Some vehicles ahead in your lane cannot
be recognized by the sensor as follows:
- Narrow vehicles such as motorcycles orbicycles
- Vehicles offset to one side
- Slow-moving vehicles or sudden-decel- erating vehicles
- Stopped vehicles
- Vehicles with small rear profile such as trailers with no loads

Driving your vehicle
A vehicle ahead cannot be recognized
correctly by the sensor if any of followingoccurs:
- When the vehicle is pointing upwardsdue to overloading in the trunk
- While the steering wheel is operating
- When driving to one side of the lane
- When driving on narrow lanes or on curves
Apply the brakes or accelerator pedal if
necessary.(Continued)
The smart cruise control system is not a substitute for safe driving
practices but a convenience
function only. It is the responsi-
bility of the driver to always
check the speed and the distance
to the vehicle ahead.
Always be aware of the selected speed and vehicle to vehicle dis-
tance.
Always maintain sufficient brak- ing distance and decelerate your
vehicle by applying the brakes if
necessary.
As the smart cruise control sys- tem may not recognize complex
driving situations, always payattention to driving conditions
and control your vehicle speed.
For safe operation, carefully read and follow the instructions in this
manual before use.WARNING
The vehicle cannot be stopped by using the smart cruise control system.
If an emergency stop is neces-
sary, you must apply the brakes.
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, it may causea serious collision.
The smart cruise control system can not recognize a stopped
vehicle, pedestrians or an
oncoming vehicle. Always look
ahead cautiously to prevent
unexpected and sudden situa-
tions from occurring.
In front of you, vehicles moving 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 look ahead
cautiously to prevent unexpected
and sudden situations fromoccurring.
(Continued)
CAUTION
The smart cruise control systemmay not operate temporarily due to electrical interference.
