62 STARTING AND OPERATING When operating in TOW/HAUL mode, the 2-Mode Hybrid Transmission will select gear ratios that maximize towing power, with less emphasis on fuel economy. NOTE: Electric only mode and engine stop-start are disabled then TOW/HAUL is activated. The TOW/HAUL light will illuminate in the instrument cluster to indicate when the switch has been activated. Pressing the switch a second time restores normal operation. FOUR-WHEEL DRIVE OPERATION MP 3010 "Active On Demand" Transfer Case The MP 3010 is a single speed (4 HI range only) transfer case which provides convenient full-time four-wheel drive. No driver interaction is required. Proper operation of four-wheel drive vehicles depends on tires of equal size, type and circumference on each wheel. Any difference in tire size can cause damage to the transfer case. Because four-wheel drive provides improved traction, there is a tendency to exceed safe turning and stopping speeds. Do not go faster than road conditions permit. This four-wheel drive (4WD) system allows the front and rear wheels to rotate at different speeds when required by the road condition or road surface. The "SVC 4WD" warning light monitors the electric shift 4WD system. If this light remains on after engine start up or illuminates during driving, it means that the 4WD system is not functioning properly and that service is required. See your authorized dealer for immediate service.
