RCCA Malfunction and Limitations

RCCA malfunction

When RCCA or a related component malfunctions, a warning message and the Master X warning light appears on the instrument cluster. Also, when the rear view mirror is not working properly, a warning message and the Master X warning light appears on the instrument cluster. When the detecting sensors are obscured, the system may be temporarily limited or disabled. The system operates properly when foreign material is removed from the sensors. If the system does not operate properly after it is removed, have your vehicle inspected by an authorized HYUNDAI dealer.

For more information, refer to Driver Assistance System Warnings and Indicators.

Turn off RCCA to install or remove a trailer, carrier, or another attachment. Turn on RCCA when finished.

Detecting sensors

RCCA uses the following sensor:

  • Rear corner radars

For more information, refer to Sensor Information and Blind-Spot Collision-Avoidance Assist (BCA).

Braking control may not work, driver's attention is required in the following circumstances:

  • The vehicle severely vibrates while driving over a bumpy road, uneven road, or concrete patch

  • Driving on a slippery surface due to snow, water puddle, ice, etc.

  • When you are towing a trailer or another vehicle, turn off RCCA for safety reasons.

  • RCCA may not operate properly if interfered by strong electromagnetic waves.

  • RCCA may not operate for 3 seconds after the vehicle is started, or the rear corner radars are initialized.

  • If the vehicle is turned off and restarted while the radar is blocked or malfunctioned, the condition is maintained. Therefore, RCCA may not operate properly.
