Anti-Lock Brake System (ABS)

~3min read

WARNING

The Anti-lock Brake System (ABS) or Electronic Stability Control (ESC) system will not prevent accidents caused by improper or hazardous driving maneuvers. Although vehicle control is improved during emergency braking, always maintain a safe distance between your vehicle and objects in front of you. Vehicle speed should always be reduced under extreme road conditions. Braking distance for vehicles equipped with ABS or ESC may be longer than for vehicles without these systems under the following road conditions.

Drive at reduced speed under the following conditions:

  • Rough, gravel, or snow-covered roads.
  • Roads with a damaged surface or uneven height.
  • Snow chains are installed on your vehicle.

Do not test the safety functions of a vehicle equipped with ABS or ESC at high speed or while cornering. This may endanger your safety or the safety of others.

ABS is an electronic brake system that helps prevent wheel lock-up during braking. ABS allows the driver to steer the vehicle while braking.

Using ABS

To get the maximum benefit from ABS in an emergency, do not try to modulate brake pressure or pump the brakes. Depress the brake pedal as firmly as possible.

When you apply the brakes under conditions that may lock the wheels, you may hear brake noise or feel a pulsation in the brake pedal. This is normal and indicates that your ABS is active.

ABS does not reduce the time or distance required to stop the vehicle.

Always keep a safe distance from the vehicle ahead.

ABS cannot prevent skidding caused by sudden changes of direction, such as entering a curve too fast or changing lanes abruptly. Always drive at a safe speed for the road and weather conditions.

ABS cannot prevent loss of directional stability. Always hold the steering wheel firmly when braking hard. Sudden or excessive steering may cause your vehicle to slide into oncoming traffic or leave the road.

On loose or uneven road surfaces, ABS operation may result in a longer braking distance than vehicles equipped with a conventional brake system.

ABS warning light (Hyundai Elantra. Anti-lock Brake System (ABS)) remains on for a few seconds after turning the ignition switch to the ON position. During this time, the ABS performs a self-diagnosis and the light turns off if everything is normal. If the light stays on, there may be a problem with the ABS. Contact an authorized HYUNDAI dealer as soon as possible.

WARNING

If the ABS warning light ( Hyundai Elantra. Anti-lock Brake System (ABS) ) stays illuminated, there may be a problem with the ABS. Your conventional brakes will still function normally. To reduce the risk of serious injury or death, contact an authorized HYUNDAI dealer as soon as possible.

CAUTION

When driving on a road with poor traction, such as an icy road, and applying the brakes continuously, ABS will be active continuously and the ABS warning light ( Hyundai Elantra. Anti-lock Brake System (ABS) ) may illuminate. Pull your vehicle over to a safe location and turn off the engine.

Restart the engine. If the ABS warning light does not illuminate, your ABS system is operating normally. Otherwise, there may be a problem with the ABS system. Contact an authorized HYUNDAI dealer as soon as possible.

Information

When you start your vehicle from an external power source due to a discharged battery, the ABS warning light ( Hyundai Elantra. Anti-lock Brake System (ABS) ) may illuminate at the same time. This is caused by low battery voltage. It does not mean that your ABS is malfunctioning. Charge the battery before driving the vehicle.
