BLIND SPOT DETECTION SYSTEM (BSD) (IF EQUIPPED)
06.-
The BSD (Blind spot detection) system
uses a radar sensor to alert the driver while driving.
It senses the rear side territory of the
vehicle and provides information to the
driver. 1. BSD (Blind spot detection)
Warning range is dependent on
your vehicle speed. However, if the
speed of your vehicle is faster by
10 km/h or more than other nearby
vehicles, the warning is not operat‐
ed.
2. LCA (Lane change assist) When vehicles are approaching toyour vehicle at high speed, the
warning is operated.
3. RCTA (Rear cross traffic alert) When your vehicle moves back‐
ward, the sensor detects approach‐
ing vehicles to the left or right side
direction and warning is operated.
WARNING
•Always check the road conditionwhile driving for unexpected situa‐tions even though the BSD (Blindspot detection) system is operat‐ing.
•BSD (Blind spot detection) systemis a system made for convenience.Do not solely rely on the systembut always pay attention to drivesafely.
