Range Selection Mode
In Brief
The Range Selection Mode switch,
if equipped, is on the shift lever.

all lower gears accessible. As
an example, when 5 (Fifth)
gear is selected, 1 (First)
through 5 (Fifth) gears are
available.
2. Press the plus/minus buttons
on the shift lever to select the
desired range of gears for
current driving conditions. See
Manual Mode 0 258.
While using Range Selection Mode,

Mode can be used.
Grade Braking is not available when
Range Selection Mode is active.
See Tow/Haul Mode 0 261.
