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.
Four–wheel drive (4WD) supplies power to all four wheels. 4WD should
not be operated on dry pavement; driveline damage may occur.
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. Refer
to Shifting to/from 4WD Low for proper operation.
