4WD switch positions
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: If your vehicle is equipped with AdvanceTrac® with RSC®, the
system will automatically turn off the stability enhancement feature
when you shift the 4WD system into 4L (4X4 LOW). You can manually
turn the system off by pressing the AdvanceTrac button, see the
Traction Control chapter for more information. This will disable the
engine management feature, allowing the vehicle to maintain full power
and enhanced momentum through the obstacle. The brake traction
enhancement feature will still be enabled.
Note: The Control Trac® selector knob should not be changed while the
rear wheels are slipping.
The Control Trac® 4WD system functions in
four modes:
• 2H (4X2) delivers power to the rear wheels
only. The message center will momentarily
display 4x2 when this mode is selected. This
mode is appropriate for normal on-road
driving on dry pavement and provides best
fuel economy.
• 4A (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 mode is selected. This mode is
appropriate for all on-road driving conditions, such as dry road
surfaces, wet pavement, snow or gravel.
• 4H (4X4) provides electronically locked four-wheel drive power to
front and rear wheels. The message center will display 4X4 when this
mode is selected. This mode is not recommended for use on dry
pavement. This mode is only intended for severe winter or off-road
conditions, such as deep snow, ice or shallow sand.
