STARTING AND OPERATING 235 Anti-Lock Brake System (ABS) The Anti-Lock Brake System (ABS) provides increased vehicle stability and brake performance under most braking conditions. The system automatically "pumps" the brakes during severe braking conditions to prevent wheel lock-up. The Electronic Brake Force Distribution (EBD) prevents the rear wheels from over-braking and provides greater control of available braking forces applied to the rear axle. When the vehicle is driven over 7 mph (11 km/h), you may also hear a slight clicking sound as well as some related motor noises. These noises are the system performing its self check cycle to ensure that the ABS system is working properly. This self check occurs each time the vehicle is started and accelerated past 7 mph (11 km/h). ABS is activated during braking under certain road or stopping conditions. ABS-inducing conditions can include ice, snow, gravel, bumps, railroad tracks, loose debris, or panic stops. You also may experience the following when the brake system goes into Anti-Lock: • The ABS motor running (it may continue to run for a short time after the stop), • The clicking sound of solenoid valves, • Brake pedal pulsations, and • A slight drop or fall away of the brake pedal at the end of the stop. These are all normal characteristics of ABS. 5
