Driving 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. Use of 4X4 mode on these surfaces may produce some noise (such as occasional clunks) but will not damage drive components. Your 4x4 features the heavy-duty Control Trac system which includes a computer-operated transfer case. This unique system is interactive with the road, continually monitoring and adjusting torque delivery to the front and rear wheels to optimize vehicle control. System indicator messages The Control Trac system indicator messages display in the reconfigurable telltale (RTT) location in the message center only under the following conditions. If these messages display when driving in 4X2, contact your authorized dealer as soon as possible. Refer to Warning lights and chimes in the Instrument Cluster chapter. • 4X4 AUTO - displays when 4X4 AUTO is selected. • 4X4 - displays when 4X4 is selected. Positions of the Control Trac system The Control Trac system functions in three modes: • 4X2 (2WD) delivers power to 4X4 4X2 4X4 the rear wheels only. This is AUTO 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 RTT location in 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 RTT location in 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. 276 2009 Navigator (nav) Owners Guide, 2nd Printing USA (fus)

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.
Use of 4X4 mode on these surfaces may produce some noise (such as
occasional clunks) but will not damage drive components.
Your 4x4 features the heavy-duty Control Trac system which includes a
computer-operated transfer case. This unique system is interactive with
the road, continually monitoring and adjusting torque delivery to the
front and rear wheels to optimize vehicle control.
System indicator messages
The Control Trac system indicator messages display in the reconfigurable
telltale (RTT) location in the message center only under the following
conditions. If these messages display when driving in 4X2, contact your
authorized dealer as soon as possible. Refer to
Warning lights and
chimes
in the
Instrument Cluster
chapter.
4X4 AUTO
– displays when 4X4 AUTO is selected.
4X4
– displays when 4X4 is selected.
Positions of the Control Trac system
The Control Trac system functions
in three modes:
4X2 (2WD)
delivers power to
the rear wheels only. 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 RTT location in 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 RTT location in 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.
