Driving 1 (First) Use 1 (First) to provide maximum engine braking on steep downgrades. Upshifts can be made by shifting to 2 (Second) or to (Overdrive). Selecting 1 (Low) at higher speeds causes the transmission to shift to a lower gear and will shift to 1 (First) after the vehicle decelerates to the proper vehicle speed. Forced Downshifts To gain acceleration in (Overdrive) or Drive (O/D OFF) when passing another vehicle, push the accelerator to the floor. The transmission will downshift to the appropriate gear: fourth, third, second or first gear. 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. 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. CONTROL-TRAC AUTOMATIC FOUR-WHEEL DRIVE SYSTEM (IF EQUIPPED) The 4WD system uses all four wheels to power the vehicle. This increases traction, enabling you to drive your 4x4 over terrain and road conditions not normally traveled by two-wheel drive vehicles. Power is supplied to all four wheels through a transfer case that allows you to select a four-wheel drive mode best suited for your current driving conditions. 154
