three stages you prefer.
Slow:Vehicle speed to the vehicle ahead
to maintain the set distance to the
vehicle ahead is slower than nor-
mal speed.
Normal: Vehicle speed to the vehicle ahead
to maintain the set distance to the
vehicle ahead is normal
Fast: Vehicle speed to the vehicle ahead
to maintain the set distance to the
vehicle ahead is faster than normal
speed.
✽ ✽ NOTICE
The last selected mode remains in
the system.
To convert to cruise control

Limitations of the system
The 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
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.

Driving your vehicle
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 and driving conditions ahead.
Lane changing
A vehicle which moves into yourlane from an adjacent lane cannot
be recognized by the sensor until it
is in the sensor's detection range.
The sensor may not detect imme- diately when a vehicle cuts in sud-
denly. 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 main-
tain 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.

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.
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 your vehicle
When vehicles are at a standstilland 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. Always look out for pedestrians
when 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.

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 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.
(Continued)
(Continued)Always look ahead to prevent
unexpected and sudden situa-
tions from occurring.
Vehicles moving in front of you 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 drive cautiously to
pre-vent unexpected and sud-
den situations from occur-
ring.
Always be aware of the select- ed speed and vehicle to vehi-
cle distance. The driver
should not solely rely on the
system but always pay atten-
tion to driving conditions and
control your vehicle speed.
(Continued)(Continued)
The Smart Cruise Control sys-tem may not recognize com-
plex driving situations so
always pay attention to driv-
ing conditions and control
your vehicle speed.
For safe operation, carefully read and follow the instruc-
tions in this manual before
