Brake disc cleaning

If there is a surface rust on the brake disc or squeal can be heard, operate brake disc cleaning to clean the brake disc.

Electric energy economy may decrease whilst using brake disc cleaning because regenerative braking system is limited.

Operation

  • Press and hold AUTO HOLD button more than 3 seconds.

    • Brake disc cleaning starts when an alarm appears on the instrument cluster.

    • Regenerative braking system is limited whilst braking about 10 times when you drive, eliminating squeal and rust on the brake.

    • Brake disc cleaning is turned off automatically when the operation is over. You can also turn off the system by pressing and holding the AUTO HOLD button more than 3 seconds.

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.

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.

NOTE

  • 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 to which deicing chemicals are applied, the vehicle may witness noises from the brake or abnormal abrasion of tires because of such deicing 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.
