1996 Mercury Sable Owner's Manual - Page 232

ABS has self-check capabilities. As described above, the system turns on the ABS light each time you start your engine. After the engine is started and the ABS light turns off, the system performs another test the first time the vehicle reaches 4-9 mph (6-15 km/h). The system turns on the ABS pump motor for approximately 1/2 second. At this time, a mechanical noise may be heard. This is a normal part of the self-check feature. If a malfunction is found during this check the ABS light will come on. Vehicles with ABS are identified with a label on the front door pillar. Ford Motor Company has not found any negative effects of mobile radio transmitting equipment installed on vehicles with the ABS system providing that the radio is installed according to the radio manufacturer's instructions. However, if you have had a mobile radio transmitter installed and the check ABS light comes on (at any time other than immediately after turning the key to the ON position) have your mobile radio dealer inspect the radio installation. Also, if the ABS system is activated other than during maximum braking, have your mobile radio installation checked. Parking Brake The parking brake should be used whenever you park your vehicle. This brake is suspended just below the bottom of the instrument panel to the left of the brake pedal. 205
