Changing Drive Mode [NOTICE] ◆ Operating the drive mode select switch when traveling or when the transmission is not in Neutral may damage the transmission or other components. Before operating the switch, be sure to stop the vehicle and shift into Neutral. ◆ In four-wheel drive mode, a greater torque load is applied to the drive system than in two-wheel drive mode. Therefore, traveling in four-wheel drive mode for long periods of time can cause the tires to wear quickly and can damage the drive system. If there is no reason to use four-wheel drive mode, return to two-wheel drive mode as soon as possible. ◆ Traveling with the indicator lamps which correspond to the actual condition of the drive mode select switch until will lead to damage to the transmission. ◆ Continuously driving the front wheels without driving the rear wheels damages the transmission bearings and other components. If there is need to drive the wheels when the tires are off the ground while the outriggers are extended, do so in the four-wheel drive mode. To perform this operation, position the tires straight ahead. Do not allow persons to come near the operating place.
