Your Mercedes-Benz relying on sensors and safety 
Unfortunately, the owner’s manual doesn’t say anything about this warning message and this “yellow battery symbol Start Engine See Owner's Manual” or On Mercedes-Benz Sprinter it could show start engine see operator's manual (as each model may display similar but little bit different message) warning message typically makes it difficult for the car owner to understand the actual problem when this message pops up on their dashboard and how to respond this could really be cumbersome. A Genuine Mercedes Benz battery is specifically designed to stay durable for at least 6-8 years to work optimally and usually requires replacement even after that long time.
When to consider your Mercedes Benz battery needs a change?
You really don’t have to be an automobile technician to know when your Mercedes battery will need replacement. Over time, the components inside the battery will wear out and become less effective resulting in a slow engine start or sometimes the check engine light is on; sending you signals on dying battery of your Mercedes Benz. It is recommended to consider replacement of your car’s battery when it starts weakening due to being too old, signaling any malfunctioning or being corroded.
What’s really annoying about this start engine warning message on the dashboard is that it says start engine – but you cannot do it because the battery is depleted.
You can jump start a car- no problem at all, you can change a battery on the spot by bringing a new car battery with you. Alternatively, you can tow the car to the dealer but it is the most expensive option of all, yet the safest on the other hand.
Charging your Mercedes Battery is another Option
All cars re-charge battery whilst driving and receiving a “Start Engine” warning message may mean that the battery voltage has dropped below the normal threshold (i.e around 12.6 volts or above with engine off)and the car is asking you to start the engine to recharge battery. Leave the engine running a few minutes or drive for 10-15 minutes to allow for battery regeneration.
Get a new battery installed
This may happen to a car parked for sometime or for a week or long but once it is ignited and message displayed, there is literally no way to put the car back in neutral gear. Sadly, it will remain parked until towed. If you are a DIY car enthusiast, you can change your vehicle’s battery yourself on the spot. Other option is same as mentioned before; to jump start a car and then turn off all possible functions such as A/C, Radio, lights and so on and taking it to a good driver to let it recharge. All you need to know is the right specifications and power capacity. The majority of models from the automaker are equipped with an AGM H8 battery but if you are concerned about replacing the battery in your vehicle with an exact match; consult the user’s manual for specs or contact the dealership to identify and install the true type of Mercedes battery.
