FOUR-WHEEL DRIVE (4WD) OPERATION (IF EQUIPPED)
WARNING: For important information regarding safe operation
of this type of vehicle, see Preparing to drive your vehicle in
this chapter.
Four–wheel drive (4WD) supplies power to all four wheels. 4WD should

no reason for concern. Refer to Shifting to/from 4L (4X4 Low) for
proper operation.
