STARTING AND OPERATING 253 BRAKE SYSTEM Your vehicle is equipped with dual hydraulic brake systems. If either of the two hydraulic systems loses normal capability, the remaining system will still function. There will be some loss of overall braking effectiveness. This may be evident by increased pedal travel during application, greater pedal force required to slow or stop, and potential activation of the Brake Warning Light. In the event power assist is lost for any reason (for example, repeated brake applications with the engine off) the brakes will still function. The effort required to brake the vehicle will be much greater than that required with the power system operating. Anti-Lock Brake System - If Equipped The Anti-Lock Brake System 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. 5
