System Limitations
The system uses a camera mounted in the windshield and radar on the front bumper to monitor driving conditions in front of the vehicle. The system may not work properly if any situation is outside of the sensing range or may not operate properly.
| The System may be limited when : |
| • |
The radar sensor or camera is restricted with a foreign object or debris. |
| • |
The camera lens is contaminated due to tinted filmed or coated windshield, damaged glass, or stuck of foreign matter (sticker, bug, etc.) on the glass. |
| • |
Inclement weather such as heavy rain or snow obscures the field of view of the radar sensor or camera. |
| • |
The target in front is too small to be detected |
| • |
The vehicle in front is an oversize vehicle or trailer that is too big to be detected by the camera recognition system (for example a tractor trailer, etc.). |
| • |
The camera's field of view is not well illuminated (either too dark or too much reflection or too much backlight that obscures the field of view) |
| • |
The vehicle in front does not have their rear lights ON or their rear lights are located in an unsual location (modified). |
| • |
The windshield glass is fogged up and the clear view of the road has been obstructed. |
| • |
The camera or radar is damaged. |
