It puts the transmission into Manual mode. C=Comfort, S=Sport, M=Manual.

Does the transmission automatic match the correct engine rev on downshifts, like the amg speedshift does on M mode??

Thanks

No rev matching.

Matching the RPM's to the MPH of the car. When you downshift your revs should be higher. For example, you're going 40MPH in 3rd and your RPMs are 3000. If you downshift to 2nd at 40MPH your revs might be 3800 to match your speed.

The primary reason that it is done is to keep the car stable and not upset the balance. At high speed, if you go into a lower gear without rev matching the car loses traction in the rear.

It's the reason people learn "heel/toe" shifting in a manual car. H/T lets you brake and work the accelerator with your right foot while clutching with the left.

You can still use the paddles or the shift lever to manually shift even while in C or S mode. The M mode just provides faster, more responsive manual shifts.
