been changed due to accelerating or
decelerating of the front vehicle, the
distance on the LCD display may change.

Smart Cruise Control may have limits
to its ability to detect distance to the
vehicle ahead due to road and traffic
conditions.
OADAS014SDOADAS014SD
• Driving on a curved road
Smart Cruise Control 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
recognized suddenly.
Select the appropriate set speed
on curves and apply the brakes or
accelerator pedal if necessary.
OADAS015SDOADAS015SD
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 Smart Cruise Control.
OADAS012SDOADAS012SD
• Driving on an inclined road
During uphill or downhill driving,
Smart Cruise Control 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.

[A]: Your vehicle, [B]: Lane changing vehicle
• Changing lanes
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 immediately
when a vehicle cuts in suddenly.
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.
