Brake Disc Cleaning (BDC)

If there is surface rust on the brake disc or squeal can be heard, the use BDC function to reduce noise and rust. While using the BDC function, the regenerative brake system will be temporarily deactivated and energy consumption may increase.

Operation

  • Press AUTO HOLD button for more than 3 seconds.

    • If the message displays on the instrument cluster, BDC function is activated.

    • Depress the brake pedal around 10 times and the regenerative braking will be temporarily deactivated. The rust and noise will be reduced. BDC operation time can change per braking conditions.

    • BDC function will automatically deactivate after operation. To manually turn it off, turn the vehicle to off position or press AUTO HOLD button for more than 3 seconds.

CAUTION

  • Do not drive with your foot resting on the brake pedal. This will create abnormally high brake temperatures which can cause excessive brake lining and pad wear.

  • Do not continue to drive with worn brake pads. Continuing to drive with worn brake pads can damage the braking system and result in costly brake repairs.

NOTICE

  • Do not continue depressing the brake pedal if the READY indicator is OFF. The battery may be discharged.

  • Noise and vibration generated during braking is normal.

  • Under normal operation, electric brake pump noise and motor vibration may occur temporarily in below cases.

    • When the pedal is depressed suddenly.

    • When the pedal is repeatedly depressed in short intervals.

    • When the ABS function is activated while braking.

  • If none are found and the condition persists, have your vehicle towed to a professional workshop and inspected. Kia recommends visiting an authorized Kia dealer/service partner.

  • Brake dust may accumulate on the wheels, even under normal driving conditions. Some dust is inevitable as the brakes wear and contribute to brake noise.

  • The driving efficiency could decrease due to regenerative system deactivated.

  • When stepping on the brake pedal under a certain driving or weather condition, you may witness your car make a sound of squealing or some other noises. This is not a brake malfunction but a normal phenomenon.

  • When driving on the road treated with de-icing chemicals, the vehicle may experience noises from the brake or abnormal abrasion of tires due to such chemicals. You should operate brake additionally so that you would be able to remove the deicing chemicals on the brake disk and pad under a safe traffic condition.

WARNING

  • Avoid applying the parking brake to stop the vehicle while it is moving except in an emergency situation. Applying the parking brake while the vehicle is moving at normal speeds can cause a sudden loss of control of the vehicle. If you must use the parking brake to stop the vehicle, use great caution in applying the brake.

  • Avoid continuous application of the brakes when descending a long or steep hill. Continuous brake application will cause the brakes to overheat and could result in a temporary loss of braking performance.

  • Do not ignore high-pitched wear sounds from your brakes. If you ignore this audible warning, you will eventually lose braking performance, which could lead to a serious accident.
