When the anti-lock brake system function is in action, you may feel the brake pedal pulsating and hear a noise. In this situation, to let the anti-lock brake system work for you, just hold the brake pedal down more firmly. Do not pump the brake. The brake pedal pulsation caused by the anti-lock brake system may indicate hazardous road surface conditions. Although the anti-lock brake system assists in providing vehicle control, it is still important to drive with all due care, because the antilock brake system cannot overcome the laws of physics that act on your vehicle: S Braking capability is dependent on tire friction with the road surface. S Even though the anti-lock brake system is operating, a driver cannot maintain full control on certain slippery road surfaces, when cornering at high speeds, or in violent maneuvers. S Avoid high speeds on wet roads. The anti-lock brake system cannot eliminate the risk of hydroplaning and loss of tire friction. Always maintain a safe distance from the vehicle in front of you. Compared with vehicles not fitted with an anti-lock brake system, your vehicle may require a longer stopping distance in the following cases: S Driving on rough, gravel or snow-covered roads. S Driving with tire chains installed. S Driving on roads where the road surface is pitted or has other differences in surface height. ! CAUTION Do not use tires other than the manufacturer's designated tires, and do not mix tires or wheels of different sizes. You may prevent the antilock brake system from operating at full effectiveness. Vehicles with rear differential lock system-The anti-lock brake system does not operate when the rear differential is locked. It is normal operation for the "ABS" warning light to be on at this time.
