Sensor to detect distance to the
vehicle ahead (Front view camera
and Front Radar)
„„Front view camera
ODN8A069024
Front view camera
The front view camera is a sensor
detecting the lane. If the sensors are
covered with snow, rain or foreign
substance, the system may temporarily
be cancelled and not work properly
until the system is cancelled due to the
degradation of the sensor’s detection
performance. Always keep the sensor clean. 
Refer to “Lane Keeping Assist (LKA)”
for cautions for the front camera.
„„Front radar
ODN8A069023
Front radar
The front radar is a sensor detecting
vehicles in front and maintains the
distance between them. If the sensors are covered with snow, rain
or foreign substance, the system may
temporarily be cancelled and not work
properly until the system is cancelled
due to the degradation of the sensor’s
detection performance. Always keep the sensor clean.
CAUTION
• Do 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 pressurized
water directly on the sensor or
sensor cover.
• Be careful not to apply unnecessary

Limitations of the System
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
OADAS014SD
• 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 recognized suddenly.
• Select the appropriate set speed
on curves and apply the brakes or
accelerator pedal if necessary.
OADAS015SD
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. On inclines
OADAS012SD
• 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.

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.
• If a faster vehicle which moves into
your lane, your vehicle will accelerate
to the set speed. Vehicle recognitionODN8H069198
• Some vehicles in your lane cannot be
recognized by the sensor:
- Narrow vehicles such as motorcycles or bicycles
