WARNING An increase in pedal travel will result in reduced braking capability. The brake system should be checked immediately. Rear Anti-lock Brakes Your vehicle may be equipped with a Rear Anti-lock Brake System. This system prevents at least one and often both rear wheels from completely locking up when the brakes are applied in a panic stop, for example. On vehicles equipped with an antilock braking system (ABS), a noise from the hydraulic pump motor and pulsation in the pedal may be observed during ABS braking events. Pedal pulsation coupled with noise while braking under panic conditions or on loose gravel, wet or snowy roads is normal and indicates proper functioning of the vehicle's antilock brake system. If the vehicle has continuous vibration or shudder while braking, felt mainly in the steering wheel, the vehicle most likely needs service. Even with the Anti-lock Brake System, you should be careful when braking. Front brake lock up on any surface, even on smooth pavement causes loss of steering control. Heavy braking on roads with loose surfaces such as snow or gravel, or severe pavement irregularities could also cause you to lose steering control of your vehicle. WARNING If the anti-lock brake system warning light remains on or comes on while driving, have the braking system checked by a qualified service technician as soon as possible. 156
