Driving FOUR-WHEEL DRIVE (4WD) OPERATION (IF EQUIPPED) For important information regarding safe operation of this type of vehicle, see Preparing to drive your vehicle in this chapter. When Four-wheel drive (4WD) is engaged, power is supplied to all four wheels through a transfer case. 4WD power can be selected when additional driving power is desired. 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 brought to a complete stop with the brake pedal depressed and the transmission placed in neutral (or the clutch pedal depressed on manual transmissions). 4WD 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. Electronic shift on the fly (ESOF) 4x4 system (if equipped) The 4WD system: • provides 4x4 High engagement and disengagement while the vehicle is moving. • is operated by a rotary control located on the instrument panel that allows you select 2WD, 4x4 High or 4x4 Low operation. • uses hub locks that can be engaged and disengaged automatically by using a rotary control located on the instrument panel. 123
