The Control Trac® system functions in four
modes:
• 2H delivers power to the rear wheels
only. The information display will
momentarily display 2H when this
mode is selected. This mode is
appropriate for normal on-road driving
on dry pavement and provides the best
fuel economy.
• 4A provides electronic control
four-wheel drive with power delivered
to all four wheels, as required, for
increased traction. The information
display will display 4A 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.

Four-Wheel Drive
(If Equipped)
• 4H provides electronically locked
four-wheel drive power to front and
rear wheels. The information display
will display 4H 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.
• 4L provides electronically locked
four-wheel drive when extra power at
reduced speeds is required. The
information display will display 4L
when this mode is selected. This mode
is not recommended for use on dry
pavement. Use this mode for off-road
low-speed operation or when extra
power is required, such as climbing
steep grades, going through deep sand
or pulling a boat out of the water.
Shifting between system modes
Note: Momentarily releasing the accelerator
pedal while a shift in progress message
displays will improve
engagement/disengagement performance.
Note: Do not perform this operation if the
rear wheels are slipping.
Note: Some noise may be heard as the
system shifts or engages; this is normal.
You can move the control from 2H, 4A or
4H at a stop or while driving. The
information display may display a message
indicating a 4X4 shift is in progress. Once
the shift is complete the information
display will then display the system mode
selected.
Shifting to or from 4L
Note: 4L mode is not intended for use on
dry pavement.
1. Bring the vehicle to a rolling speed of
3 mph (5 km/h) or less.
2. Place the gearshift in neutral (N).
