2-4. Using other driving systems n Shifting between 2WD and 4H l Reduce your speed to less than 62 mph (100 km/h) and set the front wheel drive control switch between 2WD and 4H. When the ambient temperature is 5.0°F (-15° C) or lower, shifting from 2WD to 4H can be performed with the vehicle speed below 43 mph (70 km/h). l If the 4HI indicator does not go off when you shift from 4H to 2WD, drive straight ahead while accelerating or decelerating, or drive in reverse. n Four-wheel drive usage frequency You should drive in four-wheel drive for at least 10 miles (16 km) each month. This will assure that the front drive components are lubricated. n The center differential lock switch can be operated when l The front wheel drive control switch is in the 4H or 4L position. l The vehicle speed is less than 62 mph (100 km/h) n Center differential lock system l When the front wheel drive control switch is in the 4L position and the center differential is locked, the VSC is automatically turned off. l When the front wheel drive control switch is turned to the 2WD position, the center differential is automatically unlocked. l If the operation is not completed, the center differential lock indicator blinks. If the indicator does not go off when unlocking the center differential, drive straight ahead while accelerating or decelerating, or drive in reverse. n If the 4LO indicator, 4HI indicator or the center differential lock indicator blinks l If the 4LO indicator continues to blink when shifting between 4H and 4L, stop the vehicle completely, move the shift lever to N and operate the switch again. l If the shift lever is moved before the 4LO indicator turns on/off, the transfer mode may not be shifted completely. The transfer mode disengages both the front and rear driveshafts from the powertrain and allows the vehicle to move regardless of the shift position. (At this time, the indicator blinks and the buzzer sounds.) 218
