in the lane. (A vehicle will appear in
front of your vehicle in the LCD dis‐
play only when there is an actual ve‐
hicle in front of you)
• If the vehicle ahead speeds up, your vehicle will travel at a steady cruising
speed after accelerating to the selec‐
ted speed.
CAUTION
•The warning chime sounds andLCD display blinks if it is hard tomaintain the selected distance tothe vehicle ahead.
•If the warning chime sounds, ac‐tively adjust the vehicle speed bydepressing the brake pedal accord‐ing to the road condition aheadand driving condition.

Collision alert
0+'
When the ASCC system is on, and there
is a high risk of collision due to sudden braking of the vehicle in front or not
securing enough space with the vehicle
in front, the driver needs to control the brake system or the steering wheel
manually. In this case, the collision alert
warning displays on the instrument cluster and warning sounds. Decrease
vehicle speed immediately.
WARNING
•Even when the indicator displayingthe distance with the vehicle infront does not blink or the collisionalert does not sound, always drivesafely.
•Depending on the use of radio,sound quality, and driving condi‐tions, you may not be able to hearthe warning sound. Therefore, al‐ways pay close attention to trafficin front.

The driver may choose to only use the
cruise control mode (speed control function) by doing as follows: 1. Turn the advanced smart cruise control system on (the cruise indi‐
cator light will be on but the sys‐
tem will not be activated).
2. Push the distance to distance switch for more than 2 seconds.
3. Choose between "Advanced smart cruise control (SCC) mode" and
"Cruise control (CC) mode".
WARNING
When using the cruise control mode,you must manually access the dis‐tance to other vehicles as the sys‐tem will not automatically brake toslow down for other vehicles.
Limitations of the system
0+'
The advanced smart cruise control sys‐
tem may have limits to its ability to de‐ tect distance to the vehicle ahead due
to road and traffic conditions.
On curves
• On curves, the advanced smart cruise control system may not detect a
moving vehicle in your lane, and then your vehicle could accelerate to the
set speed. Also, the vehicle speed will
rapidly down when the vehicle ahead
is recognized suddenly. • Select the appropriate set speed on
curves and adjust your vehicle speedby depressing the accelerator or
brake pedal according to the road
condition ahead and driving condition.
0+'
• Your vehicle speed can be reduced due to a vehicle in the adjacent lane.
Adjust your vehicle speed by depress‐ ing the brake pedal according to the
road condition ahead and driving con‐
dition. Apply the accelerator pedal
and select the appropriate set speed.
Check to be sure that the road condi‐ tions permit safe operation of the
advanced smart cruise control.

On inclines
0+'
• During uphill or downhill driving, theadvanced smart cruise control sys‐
tem 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 down
when the vehicle ahead is recognized
suddenly.
• Select the appropriate set speed on inclines and adjust your vehicle speed
by depressing the accelerator or
brake pedal according to the road
condition ahead and driving condition.
Lane changing
0+'
• A vehicle which moves into your lane from an adjacent lane cannot be rec‐
ognized by the sensor until it is in the sensor's detection range.
• The sensor may not detect immedi‐ ately 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, yourspeed 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.
0+'
• Your vehicle may accelerate when a vehicle ahead of you disappears.

- Narrow vehicles such as motorcycles
or bicycles
- Vehicles offset to one side
- Slow-moving vehicles or sudden-de‐
celerating vehicles
- Stopped vehicles
- Vehicles with small rear profile such
as trailers with no loads A vehicle ahead cannot be recognized
correctly by the sensor if any of follow‐
ing occurs:
- When the vehicle is pointing upwards
due to overloading in the trunk
- While making turns by steering
- When driving to one side of the lane
- When driving on narrow lanes or on
curves
Adjust your vehicle speed by depressing
the brake pedal according to the road
condition ahead and driving condition.

•Keep a safe distance according toroad conditions and vehicle speed.If the vehicle to vehicle distance istoo close during a high-speed driv‐ing, a serious collision may result.
•The advanced smart cruise controlsystem cannot recognize a stop‐ped vehicle, pedestrians or an on‐coming vehicle. Always look aheadcautiously to prevent unexpectedand sudden situations from occur‐ring.
•SCC system may have difficulty inmaintaining the correct distance orspeed, if the vehicle is driving on asteep incline or towing a trailer.
•When other vehicles are changinglanes in front of you frequently,the advanced smart cruise controlsystem may not operate appropri‐ately. Always look ahead cautious‐ly to prevent unexpected and sud‐den situations from occurring.

•The advanced smart cruise controlsystem is not a substitute for safedriving practices but a conveniencefunction only. It is the responsibili‐ty of the driver to always checkthe speed and the distance to thevehicle ahead.
•Always be aware of the selectedspeed and vehicle to vehicle dis‐tance.
•Always maintain sufficient brakingdistance and decelerate your vehi‐cle by applying the brakes if nec‐essary.
•As the advanced smart cruise con‐trol system may not recognizecomplex driving situations, alwayspay attention to driving conditionsand control your vehicle speed.
•For safe operation, carefully readand follow the instructions in thismanual before use.
•After an engine start, please stopfor several seconds. If system ini‐tialization is not completed, theSCC does not normally operate.
