Anti-Lock Brake System (ABS)

ABS provides enhanced vehicle stability and braking efficiency under most braking conditions. The system automatically prevents wheel lock-up and helps maintain steering control during braking.

ABS performs a self-check each time the vehicle is started and driven to make sure the ABS is working properly. During this self-check, you may hear a slight clicking sound and some related motor noise.

ABS activates during braking when the system detects that one or more wheels are beginning to lock up. Road conditions such as ice, snow, gravel, bumps, railroad tracks, loose debris, or emergency stops may increase the likelihood of ABS activation.

You may also notice the following normal characteristics when ABS activates:

• ABS pump motor noise or clicking sounds (you may continue to hear them for a short time after stopping)
• Brake pedal pulsation
• Slight brake pedal drop at the end of a stop

ABS is designed to work with original equipment manufacturer (OEM) tires. Modification may degrade ABS performance.

• The ABS contains complex electronic equipment that may be susceptible to interference caused by improper installation or high-output radio transmitting equipment. This interference may result in possible loss of anti-lock braking capability. Installation of such equipment must be performed by qualified specialists.
• Pumping the brakes of an anti-lock brake system will reduce braking effectiveness and may result in a collision. The pump increases braking distance. Only apply firm pressure to the brake pedal when you need to slow down or stop.
• ABS cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase braking or steering efficiency beyond what is dictated by the condition of the vehicle's brakes and tires or by traction.
• ABS cannot prevent collisions, including those resulting from excessive speed in turns, following another vehicle too closely, or hydroplaning.
• Never misuse the capabilities of a vehicle equipped with ABS in a careless or hazardous manner that could compromise the safety of the user or others.

Anti-Lock Brake System (ABS) Warning Light

The amber ABS warning light illuminates when the ignition is in the ON/RUN position and may remain on for up to four seconds.

If the ABS warning light remains on or illuminates while driving, the anti-lock portion of the brake system is not functioning and service is required. However, the conventional brake system will continue to operate normally while the ABS warning light is on.

If the brake warning light is on, the brake system should be serviced as soon as possible to restore the benefits of the anti-lock brake system. If the ABS warning light does not illuminate when the ignition is in the ON/RUN position, have the light serviced as soon as possible.
