To set vehicle to vehicle distance:
This system assists you can set the dis-
tance from the vehicle ahead and main-
tain the selected distance even if you did
not push the accelerator or the brake
pedal.The vehicle to vehicle distance will auto-
matically activate when the smart cruise
control system is on.
Select the appropriate distance accord-
ing to road conditions and vehicle speed.
Each time the button is pressed, the vehi-
cle to vehicle distance changes as fol-
lows;
Distance 3 →Distance 2 →Distance 1
For example, if you drive at 80 km/h (50
mph), the distance maintain as follows;
Distance 3 - approximately 55 m
Distance 2 - approximately 40 m
Distance 1 - approximately 26 m
✽NOTICE
The 'Distance 3' is always set when the
system is used for the first time after
starting the engine.
When the lane ahead is clear:
• The vehicle speed will maintain the set
speed.

Driving your vehicle
When there is a vehicle ahead of you
in your lane:
• Your vehicle speed will slow down or
speed up to maintain the selected dis-
tance.
• If the vehicle ahead speeds up, your
vehicle will travel at a steady cruising
speed after accelerating to the select-
ed speed.• The warning chime will sound and a
message will appear when the vehicle
speed decrease to less than 10 km/h
(6.2 mph) due to a vehicle ahead, and
the smart cruise control system will
automatically cancel.

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 control
system 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.

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 with
a soft cloth.
• Do not damage the sensor or sen-
sor area by a strong impact. If the
sensor moves slightly off posi-
tion, the smart cruise control sys-
tem will not operate correctly.
If this occurs, have your vehicle
checked by an authorized
HYUNDAI 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 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 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 or
bicycles
- 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 following
occurs:
- When the vehicle is pointing upwards
due 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 pay
attention 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 cause
a 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 from
occurring.
(Continued)
CAUTION
The smart cruise control system
may not operate temporarily due to
electrical interference.

VSM detects the distance from the vehi-
cle ahead with the sensor, to warn you
before collision and protect you in certain
hazardous situations.• If the VSM senses the object ahead too
near the vehicle and if driver's operat-
ing of the brake pedal or the steering
wheel should be needed, the warning
light illuminates.
Immediately reduce your speed.
• If the VSM senses more dangerous,
the warning sound also operates and
the accelerator pedal/seat belt
vibrates. Immediately reduce your
speed.
VEHICLE STABILITY MANAGEMENT (VSM) (IF EQUIPPED)
CAUTION
Always check the road conditions
to prevent danger even if the warn-
ing light does not illuminate, the
warning sound does not operate or
the accelerator pedal/seat belt does
not vibrate.

Brake operating
• If the VSM senses the collision, the
brake system comes to standard mode
to react promptly when the driver oper-
ates the brake pedal.
• If the driver releases the accelerator
after warning in hazardous situations,
the VSM automatically brakes the vehi-
cle gently.
• If the driver hits the brake to reduce
vehicle speed, the brake assistant sys-
tem operates to raise efficiency of
braking.
• If danger disappears, if the driver
depresses the accelerator or if the driv-
er releases the brake pedal, the brake
operating stop.
Seat belt operating
The seat belt tightens when the vehicle
senses a collision.
To cancel the VSM
• If you press the VSM OFF button, the
warning operating and brake operating
will cancel and the VSM OFF indicator
illuminates on the instrument cluster.
To turn on the VSM, press the VSM
OFF button again. The VSM OFF indi-
cator goes out.
• If you press the ESP OFF button to
turn off the ESP, the VSM will cancel,
too.
WARNING
The VSM does not stop the vehicle
completely and does not avoid col-
lision. Always look ahead cautious-
ly to prevent unexpected and sud-
den situations from occurring.
WARNING
The VSM operates according to the
distance from the vehicle ahead,
relative velocity and driver's opera-
tion of the brake or accelerator
pedal. Do not drive dangerously to
operate the VSM.

Malfunction indicator
• The VSM OFF indicator will illuminate
when the engine start/stop button is
turned ON, but should go off after
approximately 3 seconds. If the indica-
tor does not come on, or continuously
remains on after coming on for about 3
seconds when you turn the engine
start/stop button to the ON position, or
if the indicator comes on while driving,
the VSM is not working properly. Take
your vehicle to an authorized
HYUNDAI dealer and have the system
checked.
• The VSM OFF indicator may illuminate
when the ESP indicator or SCC indica-
tor comes on, but it does not indicate
malfunction of the VSM.
