REAR ANTI-LOCK BRAKE SYSTEM (R-ABS) the brakes return to normal. Avoid driving the vehicle at high speeds until the brakes function correctly. ● Avoid resting your foot on the brake pedal while driving. This will overheat the brakes, wear out the brake linings and pads faster and reduce gas mileage. ● To help reduce brake wear and to prevent the brakes from overheating, before going down a slope or long grade, reduce speed and downshift to a lower gear. ● While driving on a slippery surface, be careful when braking, accelerating or downshifting. Abrupt braking actions or sudden acceleration could cause the wheels to skid. Normal Operation The anti-lock brake system does not operate at speeds below 3 to 6 MPH (5 to 10 km/h). (The speeds vary according to road conditions.) When driving in the 2-wheel drive mode, the rear anti-lock brake system controls the rear wheels so they will not lock when braking abruptly or when braking on a slippery road. Thus, difficult steering and swerving of the vehicle due to locked rear wheels is minimized. The system detects the rear wheel rotation rate and electronically controls the pressure applied to each rear brake. Slight vibration on the brake pedal accompanied by noise usually occurs while the ABS system is operating. Such vibration and noise encountered during abrupt braking is not a problem, but indicates that the system is functioning. Even with the rear anti-lock brake system, your front wheels can still lock. If this happens, release the brake pedal slightly and then reapply pressure. lenoids controlled by a computer. The computer has a built-in diagnostic feature that tests the system each time you start the engine and move the vehicle at a low speed in forward or reverse. When the self-test occurs, you may hear a ''clunk'' noise and/or feel a ''pulsation'' in the brake pedal. This is normal and is not an indication of any malfunction. If the computer senses any malfunction, it switches the rear anti-lock brake system off and turns on the ABS brake warning light in the dashboard. The brake system then operates normally, but without anti-lock assistance. If an abnormality occurs in the system, the rear anti-lock function will cease but the ordinary brakes will continue to operate normally. The ABS brake warning light will then come on. If the light comes on while you are driving, contact your NISSAN dealer for repair. The rear anti-lock brake system may only be effective when driving in the 2-wheel drive mode. When driving in the 4-wheel drive mode, the rear anti-lock brake system may not be effective in many cases because the front axle is connected with the rear axle through Self-test feature The rear anti-lock brake system consists of an electronic sensor and two hydraulic so4-26
