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
force on the radar sensor or sensor
cover. If the sensor is forcibly
moved out of proper alignment,
Smart Cruise Control system
may not operate correctly. In this
case, a warning message may not
be displayed. Have the vehicle
inspected by an authorized HYUNDAI
dealer.
• If the front bumper becomes
damaged in the area around the
radar sensor, Smart Cruise Control
system may not operate properly.
Have the vehicle inspected by an
authorized HYUNDAI dealer.
• Use only genuine HYUNDAI parts to
repair or replace a damaged sensor
or sensor cover. Do not apply paint to
the sensor cover.
