be turned off manually by pressing the AdvanceTrac with RSC button
(refer to AdvanceTrac with Roll Stability Control™ (RSC) Stability
Enhancement System in this chapter) while operating in 2H, 4A or 4H

maneuvers. This will disable the engine management feature, allowing
the vehicle to maintain full power and enhanced momentum through the
obstacle.
WARNING: Utility and four-wheel drive vehicles are not
designed for cornering at speeds as high as passenger cars any
more than low-slung sports cars are designed to perform satisfactorily
under off-road conditions. Avoid sharp turns or abrupt maneuvers in
these vehicles.
Note: The Control Trac selector switch should not be changed while the
rear wheels are slipping.
Shifting between Control Trac system modes

message center may display 4X4 SHIFT IN PROGRESS during the
system shift. The message center will then display “4X4 AUTO” if 4X4
AUTO is selected or “4X4” if 4X4 is selected. The message center will
momentarily display “4X2” if 4X2 is selected
Note: Some noise may be heard as the system shifts or engages.
