244 Driving and Operating
Manual Mode
Range Selection Mode
Range Selection Mode helps controlthe vehicle's transmission andvehicle speed while driving downhillor towing a trailer by letting youselect a desired range of gears.
To u s e t h i s f e a t u r e :
1. Move the shift lever toM(ManualMode).
2. Press the plus/minus button onthe shift lever to select thedesired range of gears forcurrent driving conditions.
When the shift lever is moved fromD(Drive) to M(Manual Mode), anumber displays next to the M,indicating the current transmissionrange.
This number is the highest gear thatthe transmission will command whileoperating in M (Manual Mode). Allgears below that number areavailable. As driving conditionschange, the transmission canautomatically shift to lower gears.For example, when 5 (Fifth) isselected, 1 (First) through 5 (Fifth)gears are automatically shifted bythe transmission, but 6 (Sixth)cannot be used until the plus/minusbutton on the shift lever is used tochange to the range.
When the shift lever is moved fromD(Drive)toM(ManualMode),adownshift may occur. The gear thatthe transmission is operating inwhen the shift lever is moved fromD(Drive) to M(Manual Mode)determines if a downshift occurs.See the following chart.
