Hyundai Ioniq: Driving your vehicle / Braking System

Hyundai Ioniq (AE) 2017-2021 Owner's Manual / Driving your vehicle / Braking System

Power Brakes

Your vehicle has power-assisted brakes that adjust automatically through normal usage.

If the vehicle is not in the ready (Hyundai Ioniq. Braking System) mode or the vehicle is turned off while driving, the power assist for the brakes will not work.You can still stop your vehicle by applying greater force to the brake pedal than typical. The stopping distance, however, will be longer than with power brakes.

When the vehicle is not in the ready (Hyundai Ioniq. Braking System) mode, the reserve brake power is partially depleted each time the brake pedal is applied. Do not pump the brake pedal when the power assist has been interrupted.

Pump the brake pedal only when necessary to maintain steering control on slippery surfaces.

WARNING

Take the following precautions:

  • Do not drive with your foot resting on the brake pedal. This will create abnormal high brake temperatures, excessive brake lining and pad wear, and increased stopping distances.
  • When descending down a long or steep hill, move the gear shift lever to Manual Shift Mode and manually downshift to a lower gear in order to control your speed without using the brake pedal excessively. Applying the brakes continuously will cause the brakes to overheat and could result in a temporary loss of braking performance.
  • Wet brakes may impair the vehicle's ability to safely slow down; the vehicle may also pull to one side when the brakes are applied. Applying the brakes lightly will indicate whether they have been affected in this way. Always test your brakes in this fashion after driving through deep water. To dry the brakes, lightly tap the brake pedal to heat up the brakes while maintaining a safe forward speed until brake performance returns to normal. Avoid driving at high speeds until the brakes function correctly.

NOTICE

Do not depress the brake pedal continuously without the "Hyundai Ioniq. Braking System" indicator ON. The battery may be discharged.

  • Some noise and vibration may occur during braking. This is normal.
  • In below cases, some electric brake pump noise and motor vibration may occur temporarily. This is normal operation.
    - When the pedal is depressed very quickly
    - When the pedal is depressed multiple times in short intervals
    - When the ABS function is activated during braking
