Information
The distance is set to the last set dis-
tance when the system is used for the
first time after starting the vehicle.
When the lane ahead is clear:
The vehicle speed will maintain the
set speed.
When there is a vehicle ahead
of you in your lane:
Your vehicle speed will slow down
or speed up to maintain the select-
ed distance.
If the vehicle ahead speeds up,
your vehicle will travel at a steady
cruising speed after accelerating to
the set speed.
If distance from the front vehicle has
been changed due to accelerating
or decelerating of the front vehicle,
the distance on the LCD display
may change. (Only when there is a
vehicle in front, the front vehicle
appears in the LCD display.)

Even if the warning message
does not appear and warning
chime does not sound, always
pay attention to the driving
conditions to prevent danger-
ous situations from occur-
ring.
Playing the vehicle audio sys-
tem at high volume may pre-
vent occupants from hearing
the system warning sounds.
If the vehicle ahead (vehicle
speed: less than 20 mph (30
km/h)) disappears to the next
lane, the warning chime will
sound and a message "Watch
for surrounding vehicles" will
appear. Adjust your vehicle
speed for vehicles or objects
that can suddenly appear in
front of you by depressing the
brake pedal.
Always pay attention to the road
condition ahead.

In traffic situation
Use switch or pedal to accelerate
In traffic, your vehicle will stop if the
vehicle ahead of you stops. Also, if
the vehicle ahead of you starts
moving, your vehicle will start as
well. However, if the vehicle stops
for more than 3 seconds, you must
depress the accelerator pedal or
push up the toggle switch (RES+)
to start driving. If you push the Smart Cruise
Control toggle switch (RES+ or
SET-) while Auto Hold and smart
cruise control is operating the Auto
Hold will be released regardless of
accelerator pedal operation and
the vehicle will start to move. The
AUTO HOLD indicator changes
from green to white.
Sensor to detect distance to
the vehicle ahead
Smart Cruise Control uses a sensor
to detect distance to the vehicle
ahead.
If the sensor is covered with dirt or
other foreign matter, the vehicle to
vehicle distance control may not
operate correctly. Always keep the
sensor 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-
tion may stop temporarily. If this
occurs, a warning message will
appear on the cluster LCD display.
Remove any dirt, snow, or debris and
clean the radar sensor lens cover
before operating Smart Cruise
Control system. Smart Cruise
Control system may not properly
activate, if the radar is totally covered,
or if any substance is not detected
after the vehicle is in the ready ( )
mode (e.g. in an open terrain).
Information
For the SCC operation is temporarily
stopped if the radar is blocked, but
you wish to use cruise control mode
(speed control function), you must
convert to the cruise control mode
(refer to "To convert to Cruise
Control mode" in the following page.
i
OTM058061LDo 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, 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.

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.
Limitations of the system
Smart Cruise Control system may
have limits to its ability to detect dis-
tance to the vehicle ahead due to
road and traffic conditions.
On curves
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 decrease
when the vehicle ahead is recog-
nized suddenly.
Select the appropriate set speed
on curves and apply the brakes or
accelerator pedal if necessary.

Driving your vehicle
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 con-
ditions permit safe operation of
Smart Cruise Control.
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 your
lane 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 vehicle
ahead.
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 loadsA 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
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.
OAD058173N
OAD058174N
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 collision
when the system sets an object
as a target, not vehicles.
WARNING

5-108
Driving your vehicle
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. Always look out for pedestrians
when your vehicle is maintaining a
distance with the vehicle ahead. Always be cautious for vehicles
with higher height or vehicles car-
rying loads that sticks out from the
back of the vehicle.
