USING FOUR-WHEEL DRIVE (4WD) (IF EQUIPPED )
WARNING: For important information regarding safe operation
of this type of vehicle, see General Information in the Wheels
and Tires chapter.
Note: Do not use 4X4 mode on dry, hard surfaced roads. Doing so will
produce excessive noise, increase tire wear and may damage drive
components. 4X4 mode is only intended for consistently slippery or loose
surfaces.
Note: If 4X4 low is selected while the vehicle is moving above 3 mph
(5 km/h), the 4WD system will not perform a shift. This is normal and
should be no reason for concern. Refer to Shifting to/from 4L (4X4
Low) for proper operation.

remain in whichever 4X4 mode was selected prior to the fault condition
occurring. It will not default to 4X2 in all circumstances. When this
warning is displayed, have your vehicle serviced by an authorized dealer.
