Upshift according to the following chart:

The instrument cluster will show the current selected gear you are in.

In order to prevent the engine from running at too low an RPM, which may cause it to stall, the SST will automatically make some downshifts even if it has determined that you have not downshifted in time.

Although the SST will make some downshifts for you, it will still allow you to downshift at any time as long as the SST determines that the engine will not be damaged from over-revving.

Engine damage may occur if excessive engine revving is held without shifting.
