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 can be selected when additional driving power is desired. 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) If equipped with the Electronic Shift 4WD System, and 4WD Low is selected while the vehicle is moving, the 4WD system will not engage. This is normal and should be no reason for concern. Before 4WD Low can be engaged, the vehicle must be brought to a complete stop, the brake pedal depressed and the transmission placed in N (Neutral). 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 auto-manual hub locks that can be engaged and disengaged automatically based on the 4x4 mode selected. 146 2004 U137 Excursion (hdw) Owners Guide (post-2002-fmt) USA English (fus)
