NOTE
  Under the following conditions,
the radar sensor (front) may not
be able to detect vehicles ahead
or obstructions correctly and each
system may not operate normally.
 


 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.
 


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




 Visibility is reduced due to a
vehicle ahead casting off water,
snow, or sand from its tyres and
onto your windscreen.
 


 The luggage compartment is
loaded with heavy objects or the
rear passenger seats are occupied.
 


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


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

construction or lane closures.
 


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


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

slopes
 


 Driving on poor roads or unpaved
roads.
 


 The distance between your vehicle

short.
 


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


 To prevent incorrect operation of
the system, use tyres of the same
specifi ed size, manufacturer, brand,
and tread pattern on all four wheels.
In addition, do not use tyres with
signifi cantly different wear patterns
or tyre pressures on the same vehicle
(Including the temporary spare tyre).
  If the battery power is weak, the
system may not operate correctly.
  When driving on roads with little
traffi c and few vehicles ahead or
obstructions for the radar sensor to
detect, Smart Brake Support/Smart
City Brake Support (SBS/SCBS)
Warning Light (amber) temporarily
illuminates, however, this does not
