Si-Drive Control
By changing the SI-DRIVE mode switch while driving in D range, shift control can be switched among three types according to each engine characteristics.
- I mode
When I mode engine characteristics is employed, shifting is performed at the optimum point to realize low fuel consumption. Compared to S and S# mode, slip lock-up range and full lock-up range are expanded.
- S mode
When S mode engine characteristics is employed, shifting characteristics is applied so that linear acceleration can be obtained and the acceleration is even in any vehicle speed range.
- S# mode
When S# mode engine characteristics is employed, shift timing is intended for higher speed than that of S mode and is set so that full engine performance can be obtained to provide driving with great response. In addition, adaptive control is operated more actively compared to I mode or S mode to realize sportier driving performance.
