Main Menu Table Of Contents Driving with the Paddle Shifters Downshifting with the paddle shifter allows you to increase the engine braking when going down steep or long hills, and provides more power when climbing uphills. You can upshift the transmission manually to reduce the rpm. Driving in the higher gear helps fuel economy. The transmission also shifts automatically as the vehicle comes to a complete stop. It downshifts to first gear when the vehicle speed reaches 6 mph (10 km/h) or less. The automatic transmission will not allow you to change shift if: You downshift before the engine speed reaches the upper limit of the lower gear. If you try to do this, the gear position indicator will flash the number of the lower gear several times, then return to a higher gear. You upshift before the engine speed reaches the lower limit of the higher gear. You try to shift to third or a higher gear when the vehicle is stationary. You press both paddle shifters at the same time. You press one of the two paddle shifters with another paddle shifter being pressed. Here are the speed ranges for upshifting and downshifting.
