When Driving

Radar Sensor

   NOTE

y

  In the following cases, the radar sensor may not be able to detect vehicles ahead or 

obstructions.

y

  The rear surface of a vehicle ahead does not refl ect radio waves effectively, such as 

an unloaded trailer or an automobile with a loading platform covered by a soft top, 
vehicles with a hard plastic tailgate, and round-shaped vehicles.

y

  Vehicles ahead with low vehicle height and thus less area for refl ecting radio waves.

y

  Visibility is reduced due to a vehicle ahead casting off water, snow, or sand from its 

tires and onto your windshield.

y

  The trunk/luggage compartment is loaded with heavy objects or the rear passenger 

seats are occupied.

y

  Ice, snow, or soiling is on the front surface of the front emblem.

y

  During inclement weather such as rain, snow, or sand storms.

y

  When driving near facilities or objects emitting strong radio waves.

y

  In the following cases, the radar sensor may detect vehicles in the opposite lane or 

surrounding obstructions, or it may not be able to detect vehicles ahead or obstructions.

y

  The beginning and end of a curve.

y

  Roads with continuous curves.

y

  Narrow lane roads due to road construction or lane closures.

y

  The vehicle ahead enters the radar sensor's blind spot.

y

  The vehicle ahead is running abnormally due to accident or vehicle damage. 

y

  Roads with repeated up and down slopes

y

  Driving on poor roads or unpaved roads.

y

  The distance between your vehicle and the vehicle ahead is extremely short.

y

  A vehicle suddenly comes close such as by cutting into the lane. 

y

  To prevent incorrect operation of the system, use tires of the same specifi ed size, 

manufacturer, brand, and tread pattern on all four wheels. In addition, do not use tires 
with signifi cantly different wear patterns or tire pressures on the same vehicle. (Including 
the temporary spare tire)

y

  If the battery power is weak, the system may not operate correctly.

y

  When driving on roads with little traffi c and few vehicles ahead or obstructions for the 

radar sensor to detect, Forward Obstruction Warning/Smart City Brake Support (FOW/
SCBS) indicator light temporarily illuminates, however, this does not indicate a problem.
