The driver starts driving by pushingthe toggle switch up (RES+) or
down (SET-) or depressing the
accelerator pedal, after stopping
the vehicle with a vehicle stopped
far away in front.
The accelerator pedal is continu- ously depressed for more than 5
minutes.
Each of these actions will cancel
the Smart Cruise Control opera-
tion. (The Set Speed and Vehicle-
to-Vehicle Distance on the LCD
display will go off.)
In a condition the Smart Cruise
Control is canceled automatically,
the Smart Cruise Control will not
resume even though the RES+ or
SET- toggle switch is pushed. Also,
the EPB will be applied when the
vehicle is stopped.
If the Smart Cruise Control is can-
celed by other than the reasons
mentioned, have your vehicle
checked by an authorized HYUNDAI
dealer. If the system is canceled, the warn-
ing chime will sound and a message
will appear for a few seconds.
You must adjust the vehicle speed by
depressing the accelerator or brake
pedal according to the road condition
ahead and driving condition.
Always check the road conditions.
Do not rely on the warning chime.To resume Smart Cruise Control
set speed
If any method other than the
CRUISE toggle switch was used to
cancel cruising speed and the sys-
tem is still activated, the cruising
speed will automatically resume
when you push the toggle switch up
(RES+) or down (SET-).
If you push the toggle switch up
(RES+), the speed will resume to the
recently set speed. However, if vehi-
cle speed has dropped below
approximately 20 mph (30 km/h), it

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. 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.

Driving your vehicle
Always be cautious for vehicles with higher height or vehicles car-
rying loads that sticks out from the
back of the vehicle. 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.

WARNING (Continued)
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 prevent unexpected and
sudden situations from occur-
ring.
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.
