can you switch from E to S mode while in motion or a complete stop?

since my c300 has a straight pipes and muffler delete, my car has pretty loud. I realized if i drive in E mode, it's ALOT quieter (around 30-40 mph, i swear it sounds like stock) and I don't want to be the douchebag that drives through a neighborhood at 2 am and waking up everybody. Can i switch from E mode to S mode while the car is in motion or do i have to make a complete stop? :] thanks

You can do it while in motion.

I am not aware of any way to have it save in "S" mode permanently. I also noticed the manual warns one not to switch between modes while in motion. I think this is "extremely conservative" but am careful that I do not have the car under heavy acceleration/deceleration when I do switch. I don't want to confuse the transmission software and cause the engine to over rev.

All it does is force a 1st gear start and change the shift points a bit.. no reason you can't do this in motion.

The older C-class cars used to default to S. Now they default to E - formerly C. Not sure what the reasoning was behind it.

The owners manual says the car must be stopped, to cover their behinds. No problem as others said, but to avoid confusing the trans, whether really needed or not, I always switched it when the engine was at light load.

I think it's refering to case where you change from Auto to manual drive program which requires the vehicle to be stationary. Like switching from E or S to manual.

It does not mention anything about the vehicle must be in stationary in the case of switching from E to S . Therefore, I think its fine to switch between E and S mode on the fly.

Please feel free to correct me if I'm wrong, but that is how I understand it from reading the manual.

My "older" C Class stays in whatever mode I put it in - C, Manual or S before switching off. It remains in that mode until I change it again. Just my 2 cents...

You do not need to be stationary to switch to manual mode, AFAIK.

The "new" ones does not. It reverses to E EVERYTIME you turn the car off.

I do this all the time. I am just carefully to not rev up while changing. I make sure the engine it is always around 1M RPM.

For the 2013 C class manual (Edition B) it clearly say you have to be in stationary.

Look on page 150 under automatic transmission.

"Only change from automatic drive program
E or S to manual drive program M when the
vehicle is stationary."

Thanks for the clarification, Tony. In our 2008 it doesn't say that. I suppose it's because our 2008 model doesn't have a proper "manual" mode. It's basically still a "D" mode that allows you to limit the max gear +/-.

That is an interesting discussion.

Actually, I have switched between S, E and M in motion numerous times... I can't find any logical reason not to.

I saw that according to MBUSA, the vehicle had to be stationary. However, on the other hand, according to the UK Interactive Manual, you can switch between S, E and M whenever you like (http://www4.mercedes-benz.com/manual...ual_base.shtml).

Perhaps this only applies to AMG model ?

My 2013 c300 4matic only has the E and S button (no E S M)

AMG's have a selector knob: C (comfort), S (sport), S+ (sport plus ), RS (race start)...i. e. not push button. Knob selection car must be stationary.
