Driving If equipped with the Electronic Shift 4WD System, and the instrument panel control is moved to 4WD Low while the vehicle is moving, the system will not engage and no damage will occur to the 4WD system. Before 4WD Low can be engaged, the vehicle must be at a complete stop with the brake pedal depressed and the transmission in N (Neutral). 4H or 4L operation is not recommended on dry pavement. Doing so could result in difficult disengagement of the transfer case, increased tire wear and decreased fuel economy.

Automatic operation of the hub locks is recommended. • For proper operation, make sure that the arrow and the indicator dot on the hub are aligned. 4WD system indicator lights The 4WD system indicator lights illuminate only under the following conditions.
