VEHICLE DYNAMIC CONTROL (VDC) SYSTEM (if so equipped) WARNING Do not pump the brake pedal. Doing so may result in increased stopping distances. When the ABS senses that one or more wheels are close to locking up, the actuator rapidly applies and releases hydraulic pressure. This action is similar to pumping the brakes very quickly. You may feel a pulsation in the brake pedal and hear a noise from under the hood or feel a vibration from the actuator when it is operating. This is normal and indicates that the ABS is operating properly. However, the pulsation may indicate that road conditions are hazardous and extra care is required while driving. When accelerating or driving on slippery surfaces, the tires may spin or slide. With the Vehicle Dynamic Control (VDC) system, sensors detect these movements and control the braking and engine output to help improve vehicle stability. ● When the vehicle dynamic control (VDC) system is operating, the SLIP indicator in the instrument panel blinks. ● If the 4WD transfer case is shifted into 4LO indicator light will come on and the the VDC system will be turned off. See "Transfer case shifting procedures" earlier in this section. ● If the SLIP indicator blinks, the road conditions are slippery. Be sure to adjust your speed and driving to these conditions. See "Slip indicator light", and "Vehicle dynamic control (VDC) off indicator light" in the "Instruments and controls" section. If the battery is removed or discharged, the traction control system may be disabled and the SLIP and indicator lights will not turn off after 2 seconds when the ignition switch is turned to the ON position. Perform the following procedure to reset the system: ● Start the engine and set the steering wheel in the straight forward position. 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 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 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 dealer. Normal operation The ABS operates at speeds above 3 - 6 MPH (5 - 10 km/h). 5-30 Starting and driving
