Hyundai Tucson: Warning and Indicator Lights / Parking brake warning light

This warning light illuminates:

  • When the ignition switch is in the ON position. The Parking Brake warning light illuminates for about 3 seconds and then goes off once the parking brake is released.
  • Whenever the parking brake is applied.
  • Whenever 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.

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 information, refer to the “Brake Fluid” section in Chapter 9). 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 the dualdiagonal braking system. This means you still have braking on two wheels even if one of the dual systems fails.

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

Also, the vehicle does not stop in a short distance if only a portion of the braking system is working.

If you experience a malfunction with the braking system while driving, attempt to slow your vehicle by coasting or by using engine braking. You may be able to reduce your vehicle speed by manually downshifting to a lower gear. Use manual shift mode using either the gear shift lever (if equipped) or the paddle shifters (if equipped) to shift to a lower gear.

WARNING

If the Parking Brake warning light illuminates with the parking brake released, it indicates that the brake fluid level is low. Have the vehicle inspected by an authorized HYUNDAI dealer.
