ACTIVE BRAKE LIMITED SLIP (ABLS) SYSTEM (if so equipped) ● When installing a spare tire, make sure it is the proper size and type as specified on the tire placard. For tire placard location information, refer to "Tire placard" in the "Technical and consumer information" section of this manual. ● Refer to "Wheels and tires" in the "Maintenance and do-it-yourself" section of this manual. ● 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. 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 (if so equipped) 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. 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. 5-30 Starting and driving
