ACTIVE BRAKE LIMITED SLIP (ABLS) SYSTEM (if so equipped) 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. ● ABLS is a form of traction control using sensors from the Anti-lock Brake System (ABS) to transfer power from a slipping drive wheel to a wheel with more traction. The ABLS system applies braking to the slipping wheel, which helps redirect power to another wheel. ● On 4WD models the ABLS system operates in both 4H and 4LO modes. If 4WD mode is engaged, the ABLS system will operate for both drive axles. On 2WD vehicles, the ABLS system operates on the drive axle only. ● The ABLS system is always ON unless the system detects brake pad overheating. If high brake pad temperature is detected, it will turn OFF, but normal brake function will continue. ABLS will function even when the VDC system (if so equipped) is turned OFF. VEHICLE DYNAMIC CONTROL (VDC) SYSTEM 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. ● 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 may be 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. WARNING The ABLS system provides 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, and always drive carefully. 5-34 Starting and driving
