208 STARTING AND OPERATING or illuminates during driving, it means that the 4WD system is not functioning properly and that service is required. When operating your vehicle in 4LO, the engine speed is approximately three times that of the 2WD or 4HI positions at a given road speed. Take care not to overspeed the engine and do not exceed 25 mph (40 km/h). Proper operation of 4 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 4 wheel drive provides improved traction, there is a tendency to exceed safe turning and stopping speeds. Do not go faster than road conditions permit. WARNING! Always engage the parking brake when powering down the vehicle if the ؆SVC 4WD؆ light is illuminated. Not engaging the parking brake may allow the vehicle to roll which may cause personal injury. NOTE: Do not attempt to make a shift while only the front or rear wheels are spinning. The NV233 transfer case is not equipped with a synchronizer and therefore the front and rear driveshaft speeds must be equal for the shift to take place. Shifting while only the front or rear wheels are spinning can cause damage to the transfer case.
