Toyota Yaris: Automatic Transaxle Controls / Active Adaptive Shift (AAS)

Toyota Yaris XP210 (2020-2023) Owner's Manual / When Driving / Transaxle / Automatic Transaxle Controls / Active Adaptive Shift (AAS)

Active Adaptive Shift (AAS) automatically controls the transaxle shift points to best suit the road conditions and driver input. This improves driving feel. The transaxle may switch to AAS mode when driving up and down slopes, cornering, driving at high elevations, or depressing the accelerator pedal quickly while the selector lever is in the D position. Depending on the road and driving conditions/vehicle operations, gear shifting could be delayed or not occur, however, this does not indicate a problem because the AAS mode will maintain the optimum gear position.
