VEHICLE DYNAMIC CONTROL (VDC) SYSTEM WARNING ● The ABLS system helps provide increased traction, but will not prevent accidents due to abrupt steering operation or by careless driving or dangerous driving practices. Reduce vehicle speed and be especially careful when driving and cornering on slippery surfaces. Always drive carefully. ● Do not modify the vehicle's suspension. If suspension parts such as shock absorbers, struts, springs, stabilizer bars, bushings and wheels are not NISSAN approved for your vehicle or are extremely deteriorated, the ABLS system may not operate properly. This could adversely affect vehicle handling performance, and the slip indicator light may illuminate. ● If brake related parts such as brake pads, rotors and calipers are not NISSAN recommended or are extremely deteriorated, the ABLS system may not operate properly and the slip indicator light may illuminate. ● If wheels or tires other than the NISSAN recommended ones are used, the ABLS system may not operate properly and the slip indicator light may illuminate. The Vehicle Dynamic Control (VDC) system uses various sensors to monitor driver inputs and vehicle motion. Under certain driving conditions, the VDC System helps to perform the following functions: ● Controls brake pressure to reduce wheel slip on one slipping drive wheel so power is transferred to a non slipping drive wheel on the same axle. ● Controls brake pressure and engine output to reduce drive wheel slip based on vehicle speed (traction control function). ● If the 4WD transfer case is shifted into 4LO indicator light will come on and the the VDC system will be turned off. See "Using four wheel drive (4WD)" earlier in this section. ● Controls brake pressure at individual wheels and engine output to help the driver maintain control of the vehicle in the following conditions: - understeer (vehicle tends to not follow the steered path despite increased steering input) - oversteer (vehicle tends to spin due to certain road or driving conditions) The VDC system can help the driver to maintain control of the vehicle, but it can not prevent loss of vehicle control in all driving situations. indiWhen the VDC system operates, the cator in the instrument panel flashes so note the following: ● The road may be slippery or the system may determine some action is required to help keep the vehicle on the steered path. ● You may feel a pulsation in the brake pedal and hear a noise or vibration from under the hood. This is normal and indicates that the VDC system is working properly. ● Adjust your speed and driving to the road conditions. See "Slip indicator light" and "Vehicle Dynamic Control (VDC) OFF indicator light" in the "Instruments and controls" section. If a malfunction occurs in the system, the and indicator lights come on in the instrument panel. The VDC system automatically turns off when these indicator lights are on. The VDC OFF switch is used to turn off the VDC indicator illuminates to indisystem. The cate the VDC system is off. 5-34 Starting and driving
