Rear Cross-Traffic Collision Warning (RCCW) system

If the vehicle detected by the sensors approaches from the rear left/right side of your vehicle, the warning chime will sound, the warning light on the outside rearview mirror will blink and a warning will appear on the LCD display. If the rear view monitor system is in activation, a warning will also appear on the audio or AVN screen.
The warning will stop when:
- the detected vehicle moves out of the sensing area or
- when the vehicle is right behind your vehicle or
- when the vehicle is not approaching your vehicle or
- when the other vehicle slows down.
