Detecting Special Conditions
2021 Genesis G80 2.5T Advanced, AWDSECTION Detecting Special Conditions
- Rain sensor
Special Condition Operation based on special conditions detecting Splash When integrated rain sensor detects a high level of water (splash) in Direct or Intermittent mode, the system switches from Park to High speed. Then, wiping is done once in High speed and once more in Low speed. If the condition of rainfall does not change after wiping, it returns to the original condition (Direct or Intermittent). Smearing Smearing is a thin oil film that has dried fast and occurs when a small amount of rainfall is wiped by a dirty or worn-out wiper blade. Operational signal should not be issued when smearing occurs in Direct or Intermittent mode. Dirt When no change is detected after wiping, integrated rain sensor determines that the windshield is dirty. In this state, operational signal should not be issued. If the windshield becomes clean (for example, by washer fluid), the integrated rain sensor returns to the normal condition. Automatic change of sensitivity between day and night Integrated rain sensor automatically adjusts the sensitivity between day and night using a day & night sensor. Compensating for the level of illumination in the surrounding area The system operates normally by compensating for the interference due to illumination in the surrounding area. Washer fluid Integrated rain sensor does not respond to the washer fluid during the Washer mode. In other words, wiping speed does not change even if the washer fluid is sprayed (automatic operation of the washer pump is not reflected in the functioning of integrated rain sensor). - Light sensor
Special Condition Operation based on special conditions Pedestrian overpasses/high rise buildings/street trees Integrated rain sensor prevents the head lamp from blinking when it detects the light while passing by the pedestrian overpasses, high rise buildings, or street trees during the day. However, head lamp might turn on when the sensor determines it as night time while passing by the places mentioned above. Tunnels Integrated rain sensor recognizes a tunnel when the vehicle passes by it during the day. When entering the tunnel, the integrated rain sensor recognizes the tunnel and turns on the head lamp immediately and turns off the head lamp several seconds after escaping the tunnel.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
