Driving
Modes of the Control Trac system
The Control Trac system functions
in three modes:
• 4X2 (2WD) delivers power to
the rear wheels only. The
message center will momentarily
display "4x2" when this mode is
selected. This is appropriate for
normal on-road driving on dry
pavement and provides best fuel economy.
• 4X4 AUTO provides electronic control four-wheel drive with power
delivered to all four wheels, as required, for increased traction. The
message center will display "4X4 AUTO" when this position is
selected. This mode is acceptable for all on-road driving but
recommended when wet pavement, snow, or loose gravel conditions
are expected.
• 4X4 provides electronically locked four-wheel drive power to front and
rear wheels. The message center will display "4X4" when this position
is selected. This position is not recommended for use on dry
pavement. This position is only intended for severe winter or off-road
conditions, such as deep snow, ice or shallow sand.
Note: The AdvanceTrac with RSC stability enhancement system can
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
while driving in deep sand, very deep snow or more strenuous off-road
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.
