Parking brake break-in Break in the parking brake shoes whenever the holding effect of the parking brake is weakened or whenever the parking brake shoes are replaced, in order to maintain optimum braking performance. This procedure is described in the vehicle Service Manual, and it can be performed by a NISSAN certified LEAF dealer. ANTI-LOCK BRAKING SYSTEM (ABS) WARNING • The Anti-lock Braking System (ABS) is a sophisticated device, but it cannot prevent accidents resulting from careless or dangerous driving techniques. It can help maintain vehicle control during braking on slippery surfaces. Remember that stopping distances on slippery surfaces will be longer than on normal surfaces even with 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 driver is responsible for safety. • Tire type and condition may also affect braking effectiveness. - When replacing tires, install the specified size of tires on all four wheels. - For detailed information, see ؆Wheels and tires؆ in the ؆Maintenance and do-it-yourselfЉ section of this manual. The Anti-lock Braking System (ABS) controls the brakes so the wheels do not lock during hard braking or when braking on slippery surfaces. The system detects the rotation speed at each wheel and varies the brake fluid pressure to prevent each wheel from locking and sliding. By preventing each wheel from locking, the system helps the driver maintain steering control and helps to minimize swerving and spinning on slippery surfaces. WARNING Do not pump the brake pedal. Doing so may result in increased stopping distances. Self-test feature The ABS includes electronic sensors, electric pumps, hydraulic solenoids and a computer. The computer has a built-in diagnostic feature that tests the system each time you push the power switch in the READY to drive position 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 does not indicate a malfunction. If the computer senses a malfunction, it switches the ABS off and illuminates the ABS warning light on the instrument panel. The brake system then operates normally, but without anti-lock assistance. If the ABS warning light illuminates during the self-test or while driving, have the vehicle checked by a NISSAN certified LEAF dealer. Using the system Depress the brake pedal and hold it down. Depress the brake pedal with firm steady pressure, but do not pump the brakes. The ABS will operate to prevent the wheels from locking up. Steer the vehicle to avoid obstacles.
