when is it best to push to E or s mode and what is the differnce
"E" Economy mode to help conserve fuel and improve MPG. "S" Sport Mode for more aggressive, sporty driving.
ALL DEPENDS ON YOU, DO YOU WHAT TO SAFE FUEL WITH E OR GO BANANAS WITH SPORTY S, YOUR MOOD DETERMINES THE MODE
The exact answer is this: In "E" mode (some Benz's have it as "C" mode) the car will start off in 2nd gear and has lower shift points as you accelerate thru the gears. In the "S" mode, the transmission starts off in first gear and generally has higher shift points as you accelerate. Normally you should expect better gas mileage (especially on city driving) when the car is in "C" or "E" mode.
