Driving Refer to Brake system warning light in the Instrument Cluster chapter for information on the brake system warning light. ! P BRAKE Four-wheel anti-lock brake system (ABS) (if equipped) On vehicles equipped with an anti-lock 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, bumps, wet or snowy roads is normal and indicates proper functioning of the vehicle's anti-lock brake system. The ABS performs a self-check after you start the engine and begin to drive away. A brief mechanical noise may be heard during this test. This is normal. If a malfunction is found, the ABS warning light will come on. The ABS operates by detecting the onset of wheel lockup during brake applications and compensates for this tendency. The wheels are prevented from locking even when the brakes are firmly applied. Using ABS • In an emergency or when maximum efficiency from the four-wheel ABS is required, apply continuous force on the brake. The four wheel ABS will be activated immediately, thus allowing you to retain steering control of your vehicle and, providing there is sufficient space, will enable you to avoid obstacles and bring the vehicle to a controlled stop. • The anti-lock system does not reduce stopping distance. Always leave enough room between your vehicle and the vehicle in front of you to stop. • We recommend that you familiarize yourself with this braking technique. However, avoid taking any unnecessary risks. ABS warning lamp The ABS lamp in the instrument cluster momentarily illuminates when the ignition is turned on. If the light does not illuminate during start up, remains on or flashes, the ABS may be disabled and may need to be serviced. ABS 133 2004 Sable (sab) Owners Guide (post-2002-fmt) USA English (fus)
