• 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 BCW sensor does not detect
another vehicle for an extended period of time.
- When there is inclement weather
such as heavy snow or rain.
- A trailer or carrier is installed. To use the BCW
system, remove the trailer or carrier from your vehicle.
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 BCW 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.
Information
Turn off the system by pressing the BCW switch and deselecting Rear Cross-Traffic Collision warning (RCCW) from the User Settings mode on the cluster, when using a trailer or carrier behind your vehicle.
