What does the Mercedes-Benz ECO Start/Stop do?

The Mercedes-Benz ECO Start/Stop system saves fuel and reduces the vehicle’s emissions by shutting off the engine in situations where the vehicle is not in motion. The most common occurrence would be when drivers are stopped at traffic lights. It is available on select models in every Mercedes-Benz class excepting the SL-class and SLK-class Mercedes-Benz models.

When stopped for any reason, the ECO system will automatically shut off the engine, with seamless functioning. When the brake is released, the vehicle is shifted into reverse, a seatbelt is unclipped or the door is opened, the ECO system deactivates and the engine will turn back on. The engine will also remain on if the climate control system needs the engine running to heat or cool the cabin.

How do you turn on/off Mercedes-Benz’s ECO Start/Stop?

As soon as you turn on your Mercedes-Benz, the ECO Start/Stop system is activated as is the E-Mode for the transmission. When the conditions are met for system use, the ECO indicator on the instrument cluster display will light up green. While the system is being used, the ECO indicator will remain green even when the engine shuts off.

If conditions for ECO Start/Stop are not met, the indicator will be yellow and the engine will not shut off when the vehicle is stopped. To turn off the ECO Start/Stop system and E-Mode manually, simply press the ECO and E-Mode buttons on the console next to the COMAND control. Selecting Sport Mode also turns off the ECO system.

The ECO Start/Stop system is ideal for situations where there are prolonged stops. For instances such as four-way stops or driving that includes short, frequent stops, the ECO system is slightly less efficient.

    I find Eco Mode saves gas for me as it doesn’t allow me to speed quickly away at Stop signs/lights. It momentarily kicks in when you would have stepped on the gas to pull away fast, but it reminds you to slow down, which is a great thing for me because I always wanted to pull away fast, it’s teaching me to stop that! Therefore, economizing gas.

    Silly question, however I have a 2013 C250 petrol coupe and the ECO remains yellow at all times – should I assume it is indicating that the battery is not charging fully?

    Thanks in advance (from Australia).
