2H (4X2) - For general on-road driving, this mode provides optimal smoothness and fuel economy at high speeds. Sends power to the rear wheels only.
4A (4X4 AUTO) - Provides electronic controlled four-wheel drive with power delivered to the front and rear wheels, as required, for increased traction. This is appropriate for all on-road driving conditions, including dry road surfaces, but is especially useful on wet pavement, snow, dirt, or gravel.
4H (4X4 HIGH) - Provides electronically or mechanically locked four-wheel drive power to both the front and rear wheels for use in off-road or winter conditions such as deep snow, sand or mud. This mode is not for use on dry pavement.
4L (4X4 LOW) - Provides electronically or mechanically locked four-wheel drive power to both the front and rear wheels for use on low traction surfaces, but does so with additional gearing for increased torque multiplication. Intended only for off-road applications such as deep sand, steep grades, or pulling heavy objects. 4L (4X4 low) will not engage while your vehicle is moving above 3 mph (5 km/h); this is normal and should be no reason for concern. Refer to Shifting to or from 4L (4X4 low) for proper operation.
