Blind spot information system does not operate in park (P) or reverse (R).
The system may not alert you if a vehicle quickly passes through the detection zone.
Note:   For vehicles without blind spot information system with trailer coverage, aftermarket trailer tow modules or tow bars may interfere with the system. In this situation it is recommended that you switch the system off when you attach a trailer. For vehicles with a trailer tow module and tow bar approved by the manufacturer, the system automatically turns off when you attach a trailer.
