2015 Rallye with Plus Package
If you have the shifter in "manual" mode, it doesn't make any difference whether you shift gears by moving the shifter or the paddle shifters. I rarely drive in manual mode, but still use the paddle shifters to either downshift (use engine braking), or upshift to lower the RPM. If you use the paddles in auto mode, the transmission will switch back to auto (Drive) mode when you step on the accelerator. To force the transmission to switch to auto mode (useful when downshifting for engine braking), hold the upshift paddle for a couple of seconds.
