NOTICE
Warning message
Blind-Spot Collision Warning (BCW) system disabled. Radar blocked
This warning message may appear when:
- One or both of the sensors on the rear bumper is blocked by dirt or snow or
a foreign object.
- Driving in rural areas where the sensor does not detect another vehicle for an
extended period of time.
- When there is inclement weather such as heavy snow or rain.
If any of these conditions occur, the light on the BCW switch and the system will turn off automatically.
When the BCW canceled warning message is displayed in the cluster, check to make sure that the rear bumper is free from any dirt or snow in the areas where the sensor is located. Remove any dirt, snow, or foreign material that could interfere with the radar sensors.
After any dirt or debris is removed, the system should operate normally after about 10 minutes of driving the vehicle.
If the system still does not operate normally have your vehicle inspected by an authorized HYUNDAI dealer.
