Manual Transmissions
Note: See General Information in the Manual Transmissions and Clutch chapter for manual transmission operating instructions.
If equipped, a transmission range control and splitter valves are attached to the gear shift knob.
The range-preselection lever allows the selection of the low or high range for each transmission ratio. It is used once during an upshift sequence and once during a downshift sequence.
Dependent on the transmission model, some ratios can be split using the splitter-control button.
