Starting and operating/ABS (Anti-lock Brake System) ABS (Anti-lock Brake Sys- tem) S07AL WARNING Always use the utmost care in driv- ing – overconfidence because you are driving with an ABS equipped vehicle could easily lead to a serious accident. CAUTION . The ABS does not always de- crease stopping distance. You should always maintain a safe following distance from other vehicles. . When driving on badly surfaced roads, gravel roads, icy road, 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 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. The ABS prevents the lock-up of wheels which may occur during sudden braking or braking on slippery road surfaces. This helps prevent the loss of steering control and directional stability caused by wheel lock-up. When the ABS is operating, you may hear a chattering noise or feel a slight vibration in the brake pedal. This is normal when the ABS operates. The ABS will not operate when the vehicle speed is below approximately 6 mph (10 km/h). & ABS self-check S07AL01 You may feel a slight shock in the brake pedal and hear the operating noise of the ABS from the engine compartment just after the vehicle is started. This is caused by an automatic functional test of the ABS being carried out and does not indicate any abnormal condition. 7-31 Electronic Brake Force Dis- tribution (EBD) system S07AM 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 function fails, the EBD system also stops working. 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. & ABS warning light Refer to “ABS warning light” F3-19. S07AL02 – CONTINUED –
