Anti-Lock Brake System (ABS)

~3min read

WARNING

The Anti-lock Brake System (ABS) or Electronic Stability Control (ESC) will not prevent accidents resulting from improper or dangerous driving maneuvers. Although the vehicle offers improved control during emergency braking, always maintain a safe distance between you and the objects ahead. Vehicle speed must always be reduced under extreme road conditions. The braking distance for vehicles with ABS or ESC may be longer than for those without these systems on the following road conditions.

Drive your vehicle at a reduced speed under the following conditions:

  • Rough, gravel, or snow-covered roads.
  • On roads where the road surface is uneven or has differences in surface height.
  • Snow chains are installed on your vehicle.

ABS or ESC equipped vehicles must not be tested at high speed driving or cornering. This could endanger your own safety or others.

ABS is an electronic brake system that helps prevent brake lock-up. ABS allows the driver to steer and brake at the same time.

Using ABS

To get the maximum benefit from your ABS in an emergency, do not attempt to modulate brake pressure and do not attempt to pump the brakes. Press the brake pedal as hard as possible.

When you apply the brakes under conditions that may lock the wheels, you may hear noises from the brakes or feel a corresponding pulsation in the brake pedal. This is normal and means 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 in front of you.

ABS will not prevent skidding that results from sudden changes in direction, such as attempting to take a curve too fast or a sudden lane change. Always drive at a speed safe for the road and weather conditions.

ABS cannot prevent loss of stability. Always hold the steering wheel firmly when braking hard. Heavy or sudden steering movements may still cause your vehicle to swerve into oncoming traffic or off the road.

On loose or uneven road surfaces, the operation of the anti-lock brake system may result in a longer stopping distance than for vehicles equipped with a conventional brake system.

Restart the engine. If the ABS warning light does not come on, the ABS system is normal.

Information
