Blind Spot Information System Description

Blind Spot Information System (BSI)

The blind spot information system (BSI) that turns on the BSI alert indicators (A) beside the door mirrors when another vehicle in the next lane enters the "blind" area, where the driver cannot see the vehicle with his peripheral vision or with the inside and outside rearview mirrors.

NOTE:
The BSI system does not ensure the safety of the vehicle occupants, nor does it help in low visibility situations such as bad weather.
The BSI system turns on/blinks* the BSI alert indicator in the following situations.
*: When moving the turn signal lever toward the side with the BSI alert indicator on, the alert indicator blinks to alert driver.





1. Pass from rear
2. Vehicle operation speed: 6-99 mph (10-160 km/h)





3. Lane changes
4. Vehicle operation speed: 6-99 mph (10-160 km/h)
5. Relative speed: more less 12 mph (20 km/h)





6. Passing
7. Vehicle operation speed: 6-99 mph (10-160 km/h)
8. Relative speed: more less 12 mph (20 km/h)





9. Starting
10. Vehicle operation speed: 6-99 mph (10-160 km/h)





11. One or more lanes apart
12. Vehicle operation speed: 6-99 mph (10-160 km/h)





13. Oncoming cars
14. Vehicle operation speed: 6-99 mph (10-160 km/h)





15. Static objects
16. Vehicle operation speed: 6-99 mph (10-160 km/h)






Blind Spot Information (BSI) Control Unit

The BSI control unit obtains information from external sensors and switches that are connected to their respective control units.






BSI Radar Units

The blind spot information system (BSI) radar units are installed in the rear bumper on both sides.






Basic distance function

The BSI radar unit radiates 24 GHz radar waves within the range of 9.84 ft (3 m) toward the rear and 9.84 ft (3 m) on both sides horizontally and 20 degrees on both sides toward the rear. It receives the reflected radar waves when another vehicle enters in this alert area.

Aiming function

The BSI radar unit has a small amount of auto-aiming capability. Straighten the body when auto-aiming is not possible.

Self-diagnosis function

The BSI radar units have a self-diagnostic function that displays the self-diagnostic information in the MID when the system turns on with the ignition switch to ON (II).

Sensitivity-lowering detection function

When the detecting ability of the BSI radar units are hampered by dirt or other contaminants around the rear bumper that covers BSI radar units, the BSI radar units outputs this condition to the BSI control unit until the function recovers.
