On curves
On curves, the smart cruise control
system may not immediately
detect a moving vehicle in your
lane, and then your vehicle could
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 curves and adjust your vehicle
speed by depressing the accelera-
tor or brake pedal according to the
road and driving conditions ahead. Your vehicle speed can be reduced
due to a vehicle in the adjacent
lane. Adjust your vehicle speed by
depressing the brake pedal
according to the road and driving
conditions ahead. Apply the accel-
erator pedal and select the appro-
priate set speed. Check to be sure
that the road conditions permit safe
operation of the smart cruise con-
trol.
On inclines
During uphill or downhill driving,the smart cruise control system
may not immediately detect a mov-
ing vehicle in your lane, and may
cause your vehicle to accelerate to
the set speed. Also, the vehicle
speed will rapidly down when the
vehicle ahead is recognized sud-
denly.
Select the appropriate set speed on inclines and adjust your vehicle
speed by depressing the accelera-
tor or brake pedal according to the
road condition ahead and driving
condition.

Vehicle recognition
Some vehicles ahead in your lane
cannot be recognized by the sensor
as follows:
- Narrow vehicles such as motorcy-
cles or bicycles
- Vehicles offset to one side
- Slow-moving vehicles or sudden- decelerating vehicles
- Stopped vehicles
- Vehicles with small rear profiles such as trailers with no loads A vehicle ahead cannot be recog-
nized correctly by the sensor if any of
following occurs:
- When the vehicle is pointing
upwards due to overloading in the
trunk(tailgate)
- 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 accord-
ing to the road condition ahead and
driving condition. When vehicles are at a standstill
and the vehicle in front of you
changes to the next lane, be care-
ful when your vehicle starts to
move because it may not immedi-
ately recognize the stopped vehicle
in front of you.
In this case, you must maintain a
safe braking distance, and if neces-
sary, depress the brake pedal to
reduce your driving speed in order to
maintain a safe distance.

Driving your vehicle
Always look out for pedestrianswhen your vehicle is maintaining a
distance with the vehicle ahead. Always be cautious when
approaching vehicles that are taller
with higher clearance, or vehicles
carrying loads that stick out of the
back of the vehicle.

WARNING
When using the Smart Cruise
Control take the following pre-
cautions:
If an emergency stop is nec-essary, you must apply the
brakes. The vehicle cannot be
stopped at every emergency
situation by using the Smart
Cruise Control system.
Keep a safe distance accord- ing 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 deceler-
ate your vehicle by applying
the brakes if necessary.
The Smart Cruise Control sys- tem cannot recognize a
stopped vehicle, pedestrians
or an oncoming vehicle.

SMART mode (if equipped)
SMART mode selects the
proper driving mode
among ECO, COMFORT
and SPORT by judging the
driver's driving habits (i.e.
Economical or Aggressive)
from the brake pedal
depression or the steering
wheel operation.
Press the DRIVE MODE button to activate SMART mode. When
SMART mode is activated, the
indicator illuminates on the instru-
ment cluster.
The indicator illuminates in blue, when the driver's driving is catego-
rized to be mild. It illuminates in
white, when the driver's driving is
categorized to be normal. It illumi-
nates in red, when the driver's driv-
ing is categorized to be dynamic
during abrupt braking or sharp
curving. The vehicle starts in SMART
mode, when the engine was turned
OFF in SMART mode.
SMART mode automatically con- trols the vehicle driving, such as
gear shifting patterns, engine
torque, riding quality in accordance
with the driver's driving habits.
✽ ✽ NOTICE
• When you mildly drive the vehicle
in SMART mode, the driving
mode changes to ECO mode to
improve fuel efficiency. However,
the actual fuel efficiency may dif-
fer in accordance with your driv-
ing situations (i.e. upward/down-
ward slope, vehicle
deceleration/acceleration).
• When you dynamically drive the vehicle in SMART mode by
abruptly decelerating or sharply
curving, the driving mode changes
to SPORT mode. However, it may
adversely affect fuel economy.SMART

Various driving situations, which you
may encounter in SMART mode
The driving mode automatically
changes to ECO mode after a cer-
tain period of time, when you gen-
tly depress the accelerator pedal
(Your driving is categorized to be
mild.).
The driving mode automatically changes from SMART ECO mode
to SMART COMFORT mode after
a certain period of time, when you
sharply or repetitively depress the
accelerator pedal.
The driving mode automatically changes to SMART COMFORT
mode with the same driving pat-
terns, when the vehicle starts to
drive on an upward slope of a cer-
tain angle. The driving mode auto-
matically returns to SMART ECO
mode, when the vehicle enters a
leveled road. The driving mode automatically
changes to SMART SPORT, when
you abruptly accelerate the vehicle
or repetitively operate the steering
wheel (Your driving is categorized
to be sporty.). In this mode, your
vehicle drives in a lower gear for
abrupt accelerating/decelerating
and increases the engine brake
performance.
You may still sense the engine brake performance, even when you
release the accelerator pedal in
SMART SPORT mode. It is
because your vehicle remains to
be in a lower gear over a certain
period of time for next acceleration.
Thus, it is a normal driving situa-
tion, not indicating any malfunc-
tion.
The driving mode automatically changes to SMART SPORT mode
only in harsh driving situations. In
most of the normal driving situa-
tions, the driving mode sets to be
either in SMART ECO mode or in
SMART COMFORT mode. Limitation of SMART mode
The SMART mode may be limited in
following situations. (The OFF indica-
tor illuminates in those situations.)
The driver manually moves the
shift lever : It deactivates SMART
mode. The vehicle drives, as the
driver manually moves the shift
lever.
The cruise control is activated : The cruise system may deactivate
the SMART mode. When a higher
system is set by the cruise system,
it starts to control vehicle speed
and deactivates SMART mode.
(SMART mode is not deactivated
just by activing the cruise system.)
The transmission oil temperature is either extremely low or extremely
high : The SMART mode can be
active in most of the normal driving
situations. However, an extremely
high/ low transmission oil tempera-
ture may temporarily deactivate the
SMART mode, because the trans-
mission condition is out of normal
operation condition.

Driving your vehicle
✽ ✽NOTICE
• Even though the steering is assist-
ed by the system, the driver may
control the steering.
• The steering wheel may feel heav- ier when the steering wheel is
assisted by the system than when it
is not.
The system will be cancelled when:
You change lanes with the turn sig-
nal.
- Using the turn signal to changelanes.
- If you change lanes without the turn signal on, the steering wheel
might be controlled.
LKA can transit to steering assist mode when the car is near to mid-
dle of the lane after system on or
the lane was changed. LKA can
not assist steering if the vehicle fol-
lows lane marker too close contin-
uously before transition to steering
assist mode.
The control of ESC (Electronic Stability Control) or VSM (Vehicle
Stability Management) is activated.
The steering will not be assisted when you drive fast on a sharp
curve. The steering will not be assisted
when vehicle speed is below 40
mph (64 km/h). and over 110 mph
(177 km/h). Always obey all traffic
laws and drive safely.
The steering will not be assisted when you change lanes quickly.
The steering will not be assisted when you brake suddenly.
The steering will not be assisted when the lane is very wide or nar-
row.
The steering will not be assisted when only one side lane marker is
detected.
There are more than two lane markers such as a construction
area.
Radius of a curve is too small.
When you turn steering wheel sud- denly, the LKA will be disabled
temporarily.
Driving on a steep slope or hill.
