I know this is probably a dumb question but when in D what is the S for? are there any limitations on it like stay under 20 MPH?
does anyone use it?

Thanks

Extra engine breaking, more instant acceleration when I know I'm about to pass somebody. There's no real limitation on use.

As you can hear mainly pops the RPM's up higher on the torque curve.

There is one limitation listed in the manual: DO NOT accelerate while "downshifting".
