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 the transfer gear. The rear wheels lock if the front wheels lock. If this happens, the rear anti-lock brake system may cease functioning but the ordinary brakes will continue to operate normally. The ABS brake warning light will then come on. The above condition is not a malfunction and the rear anti-lock brake system recovers when the engine is started again. The ABS brake warning light then goes off. some conditions, but remember that the stopping distance on slippery surfaces will be longer than on normal surfaces even with rear wheel ABS. Stopping distances may also be longer on rough, gravel, or snow covered roads, or if you are using tire chains. Always maintain a safe distance from the vehicle in front of you. Ultimately, the responsibility for safety of self and others rests in the hands of the driver. Tire type and condition may also affect braking effectiveness. ● When replacing tires, install the specified size of tires on all four wheels. ● When installing a spare tire, make sure it is the proper size and type as specified on the tire placard. See ''Tire placard'' in the ''Technical and consumer information'' section. Using the System Depress the brake pedal and hold it down. WARNING Do not pump the brake pedal. Doing so may result in increased stopping distances. WARNING The rear anti-lock brake system is a sophisticated device. But it cannot prevent accidents resulting from careless or dangerous driving techniques. It can help maintain vehicle control under 4-26
