7-38 Starting and operating/Electronic Brake Force Distribution (EBD) system following distance from other vehicles. . When driving on badly surfaced roads, gravel roads, icy roads, or over deep newly fallen snow, stopping distances may be long- er for a vehicle with the ABS than one without. When driving under these conditions, therefore, re- duce your speed and leave ample distance from other vehicles. . When tire chains are installed, stopping distances may be long- er for a vehicle with the ABS than one without. Be sure to reduce your speed and maintain a safe distance from the vehicle in front. . When you feel the ABS operating, you should maintain constant brake pedal pressure. Do not pump the brake pedal since doing so may defeat the opera- tion of the ABS. & ABS self-check Just after the vehicle is started, you may feel on the brake pedal a vibration similar to when the ABS operates, and you may also hear the sound of the ABS working from the engine compartment. This is caused by an automatic functional test of the ABS being carried out and does not indicate a malfunction. Electronic Brake Force Dis- tribution (EBD) system & ABS warning light The EBD system maximizes the effective- ness of the brakes by allowing the rear brakes to supply a greater proportion of the braking force. It functions by adjusting the distribution of braking force to the rear wheels in accordance with the vehicle’s loading condition and speed. The EBD system is an integral part of the ABS and uses some of the ABS compo- nents to perform its function of optimizing the distribution of braking force. If any of the ABS components used by the EBD system malfunction, the EBD system also stops working. Refer to “ABS warning light” F3-21. When the EBD system is operating, you may hear a chattering noise or feel a slight vibration in the brake pedal. This is normal and does not indicate a malfunction.
