Hyundai Ioniq (AE): Warning and Indicator Lights / Parking Brake & Brake Fluid Warning Light

Hyundai Ioniq. Parking Brake & Brake Fluid Warning Light

This warning light illuminates:

  • When you place the Engine Start/ Stop button to the ON position.
    - It illuminates for approximately 3 seconds.
    - It remains on if the parking brake is applied.
  • When the parking brake is applied.
  • When the brake fluid level in the reservoir is low.
    - If the warning light illuminates with the parking brake released, it indicates the brake fluid level in the reservoir is low.
  • When the regenerative brake does not operate.

If the brake fluid level in the reservoir is low:

1. Drive carefully to the nearest safe location and stop your vehicle.

2. With the engine stopped, check the brake fluid level immediately and add fluid as required (For more details, refer to "Brake Fluid" in chapter 7). After adding brake fluid, check all brake components for fluid leaks. If a brake fluid leak is found, or if the warning light remains on, or if the brakes do not operate properly, do not drive the vehicle. Have the vehicle inspected by an authorized HYUNDAI dealer.

Dual-diagonal braking system

Your vehicle is equipped with dualdiagonal braking systems. This means you still have braking on two wheels even if one of the dual systems should fail.

With only one of the dual systems working, more than normal pedal travel and greater pedal pressure is required to stop the vehicle.

Also, the vehicle will not stop in as short a distance with only a portion of the brake system working.

If the brakes fail while you are driving, shift to a lower gear for additional engine braking and stop the vehicle as soon as it is safe to do so.

WARNING
