If there is a transfer case tooth blockage a
message appears in the instrument cluster
display. To alleviate this condition, place
the transmission in a forward gear, move
your vehicle forward approximately 5 ft
(1.5 m), and shift the transmission back to
neutral (N) to allow the transfer case to
complete the range shift.
Note: You could hear some noise as the
system shifts or engages, this is normal.
If the system detects a fault, a warning
message appears in the instrument cluster
display. See Four-Wheel Drive –
Information Messages (page 239).
