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 traffic conditions.
On curves
The Smart Cruise Control Systemmay 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 recognized suddenly.
Select the appropriate set speed on curves and apply the brakes or
accelerator pedal if necessary.
Do not install accessories
around the radar and do not
replace the bumper by your-
self. It may interfere with the
radar performance.
Always keep the radar and
bumper clean.
To prevent radar cover dam-
age from occurring, wash the
car with a soft cloth.
Do not paint the radar cover.
Do not damage the radar or
radar area by a strong impact.
If the radar moves slightly off
position, the Smart Cruise
Control System will not oper-
ate correctly. If this occurs,
have your vehicle checked by
an authorized HYUNDAI deal-
er.
Use only a genuine HYUNDAI
radar cover for 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 the
Smart Cruise Control.
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 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 yourlane from an adjacent lane cannot
be recognized by the radar until it
is in the radar'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 moves into your lane, your vehicle will accelerate to
the set speed.

Vehicle recognition
Some vehicles in your lane cannot
be recognized by the radar:
- 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 profile such as trailers with no loads A vehicle ahead cannot be recog-
nized correctly by the radar if any of
following occurs:
- When the vehicle is pointing
upwards due to overloading in the
trunk
- 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.

NOTICE
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 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
System cannot recognize a
stopped vehicle, pedestrians
or an oncoming vehicle.
Always look ahead cautiously
to prevent unexpected and
sudden situations from occur-
ring.
(Continued)
WARNING (Continued)
Vehicles moving in front of you
with a frequent lane change
may cause a delay in the sys-
tem'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 sudden
situations from occurring.
Always be aware of the select-
ed speed and vehicle to vehi-
cle distance.
The Smart Cruise Control
System may not recognize
complex driving situations so
always pay attention to driv-
ing conditions and control
your vehicle speed.

Prerequisite for activation
The AEB gets ready to be activated,
when the AEB is selected on the
LCD display, and when the following
prerequisites are satisfied.
- The ESC is activated.
- To enable the system to detectpedestrians ahead, the vehicle
driving speed must be between 5 -
40 mph (8 - 65 km/h).
- To enable the system to detect a vehicle ahead, the vehicle driving
speed must be between 5 - 110
mph (8 - 180 km/h).
When traveling above 50 mph (80
km/h), the AEB system only initiates
partial braking. This is to prevent
unintended full braking to stop in the
middle of the highway.
AEB warning message and
system control
The AEB produces warning mes-
sages and warning alarms in accor-
dance with the collision risk levels.
Also, it controls the brakes in accor-
dance with the collision risk levels.The AEB automatically acti-
vates upon placing the igni-
tion switch to the ON position.
The driver can deactivate the
AEB by canceling the system
setting on the LCD display.
The AEB automatically deacti-
vates upon canceling the
ESC. When the ESC is can-
celed, the AEB cannot be acti-
vated on the LCD display.

Emergency braking (3rdwarning)
This warning message appears on
the LCD display with a warning
alarm.
Additionally, automatic emergency braking of the vehicle is applied in
order to avoid a collision.
- If your vehicle is traveling lessthan 40 mph (65 km/h) and a
pedestrian is detected within the
Emergency Braking stage, auto-
matic emergency braking of the
vehicle is applied. In this condi-
tion, your vehicle speed will
decelerate sharply to avoid a col-
lision. - When your vehicle drives slower
than 40 mph (65 km/h) with a
passer-by in front, the driving
speed may abruptly decrease.
When your vehicle drives faster
than 40 mph (65 km/h) with a
pedestrian in front, the AEB does
not operate.
Brake operation
In an urgent situation, the braking system enters into the ready status
for prompt reaction against the dri-
ver’s depressing the brake pedal.
The AEB provides additional brak- ing power for optimum braking per-
formance, when the driver depress-
es the brake pedal.
The braking control is automatical- ly deactivated, when the driver
sharply depresses the brake pedal,
or when the driver abruptly oper-
ates the steering wheel.
The braking control is automatical- ly canceled, when risk factors dis-
appear.
OLF056451N
The driver should always use
extreme caution while operating
the vehicle, whether or not there
is a warning message or alarm
from the AEB system.
