VEHICLE DYNAMIC CONTROL (VDC) SYSTEM 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 GT-R certified NISSAN dealer. The Vehicle Dynamic Control (VDC) system uses various sensors to monitor driver inputs and vehicle motion. Under certain driving situations, the system will control braking and engine output to help keep the vehicle on its steered path. . The VDC mode can be changed using the VDC setup switch. ( "VDC, TRANSMISSION AND SUSPENSION SETUP SWITCHES" page 5-21) When the VDC system is operating, the indicator in the instrument panel blinks. If the indicator blinks, the road conditions may be slippery. Be sure to adjust your speed and driving to these conditions. Be sure to drive carefully. ( "Slip indicator light" page 2-29) ( "Vehicle Dynamic Control (VDC) off indicator light" page 229) Indicator light If a malfunction occurs in the system, the and indicator lights illuminate in the instrument panel. As long as these indicators are illuminated, the VDC system function is canceled. The VDC system uses an Active Brake Limited Slip (ABLS) function to improve vehicle traction. The ABLS system works when one of the driving wheels is spinning on a slippery surface. The . ABLS system brakes the spinning wheel, which distributes the driving power to the other drive wheel. If the vehicle is operated with the VDC setup switch pushed and the VDC system turned off, all VDC systems will be turned off. The ABLS system and ABS will still operate with the VDC system off. While the VDC system is operating, you may feel a pulsation in the brake pedal and hear a noise or feel a vibration from under the hood. This is normal and indicates that the VDC system is working properly. The VDC system 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 forward or backward. When the self-test occurs, you may hear a "clunk" noise and/or feel a pulsation in the brake pedal. This does not indicate that there is a malfunction. Normal operation The ABS operates at speeds above 3 to 6 MPH (5 to 10 km/h). The speed varies according to road conditions. 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. . . . WARNING The VDC system is designed to help improve driving stability but does not prevent accidents due to abrupt steering operation at high speeds or due to careless or dangerous driving techniques. Reduce vehicle speed and be especially careful when driving and cornering on slippery surfaces and always drive care- 5-40 Starting and driving
