Driving Your Explorer RWARNING The Anti-lock system does NOT assist the vehicle in stopping quickly on wet or icy surfaces. Heavy braking combined with poor road conditions could cause you to lose steering control of your vehicle. Using anti-lock brakes The operation of a vehicle with 4WABS is not similar to the operation of normal brakes. Some differences exist and are listed below: s Apply the brake steadily. In the event of a panic stop, do NOT "pump" the brakes. "Pumping" the brakes during an Anti-lock stop will diminish braking effectiveness. s During an Anti-lock stop, the driver will notice a brake pedal pulsation and hear some noise from the engine compartment. This is an indication that the 4WABS system is working correctly and is normal. RWARNING The Anti-lock system does NOT decrease the time necessary to apply the brakes. Always leave enough room between the vehicle in front of you and your vehicle. 4WABS driver warning light The 4WABS computer continuously monitors the system while driving for any electrical faults or system malfunctions. In addition, the 4WABS computer performs an initial system check called bulb proveout when the vehicle ignition is switched on. During bulb proveout, the ABS light on the instrument cluster will momentarily illuminate and then go out. NOTE: After starting the vehicle and upon initial drive-off, the driver may notice a single pulse of the brake pedal and a noise from the engine compartment. This is part of the initial system check and is normal. 263
