When shifting up: Move the shift selector to the + (up) side. (Shifts to higher range.) When shifting down: Move the shift selector to the (Shifts to lower range.) (down) side. ● In the manual shift mode, the transmission may shift up automatically to a higher range than selected if the engine speed is too high. When the vehicle speed decreases, the transmission automatically shifts down and shifts to 1st gear before the vehicle comes to a stop. ● CVT operation is limited to automatic drive mode when CVT fluid temperature is extremely low even if manual shift mode is selected. This is not a malfunction. When CVT fluid warms up, manual mode can be selected. ● When the CVT fluid temperature is high, the shift range may upshift in lower rpm than usual. This is not a malfunction. ● The transmission will automatically downshift the gears. (For example, if you select the 3rd range, the transmission will shift down between the 3rd and 1st gears.) ● Moving the shift selector rapidly to the same side twice will shift the ranges in succession. When canceling the manual shift mode: Return the shift selector to the D (Drive) position to return the transmission to the normal driving mode. ● In the manual shift mode, the transmission may not shift to the selected gear. This helps maintain driving performance and reduces the chance of vehicle damage or loss of control.
