Range Selection Mode
The Range Selection Mode switch, if equipped, is located on the shift lever.
To enable the Range Selection feature:
1. Move the column shift lever to the M(Manual) position. The current range will appear next to the M. This is the highest attainable range with 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, located on the steering column shift lever, to select the desired range of gears for current driving conditions. See Manual Mode on page 9‑41.
While using Range Selection Mode, cruise control and the Tow/Haul mode can be used.
Grade Braking is not available when Range Selection Mode is active.
See Tow/Haul Mode on page 9‑42.
