The W205 model was introduced in 2015.

Periodically, a cautionary notification emerges on the information display panel located inside the dashboard while entering the vehicle.
Please be advised. Please begin the engine. Please refer to the owner's manual.

However, the handbook does not include any mention of this. I have documented telephone conversations with the manufacturer, MB, as well as three authorised dealerships. Regrettably, none of the aforementioned parties have responded to my inquiries. The vehicle consistently exhibits reliable ignition, often occurring within minutes after engine shutdown, such as while refuelling. On the contrary, in the event that I am departing on a business trip and will be gone for a week, I have the option to leave my car behind. Upon my return, without any prior notice, I may encounter a situation where the car's battery has been depleted, leaving me unable to start the vehicle.

What is the cause or explanation for this situation? Does anybody have any suggestions or ideas?

Thank you for your response.

The occurrence of the "Please Start Engine" notification indicates that the battery voltage has fallen below the standard threshold. Consequently, the vehicle is requesting the user to start the engine in order to replenish the battery's charge.

If one asserts that the battery is in satisfactory condition, it is possible that the charging of the battery is sporadic, maybe due to an alternator malfunction.

Thank you, I will get it examined. One can speculate that the connections were not adequately secured subsequent to the service.

Apologies for reviving a dormant discussion, but I just received a notification upon returning from a week-long vacation, during which my battery was adequately charged.

During a two-month absence for business purposes, I left my previous Mercedes-Benz vehicle unattended. Upon my return, I saw that the vehicle started without any issues. Consequently, I am curious to know whether the current model of Mercedes-Benz would experience a depletion of its power supply during a two-week vacation, or if it employs a mechanism that gradually shuts down non-essential components in order to ensure successful engine start-up even after a prolonged period of inactivity.

It is challenging to provide a definitive answer.

While it is true that current automobiles include a greater number of active systems even when the vehicle is not in use, potentially leading to increased battery drainage compared to previous cars, it is important to note that contemporary vehicles often have an auxiliary battery to mitigate this issue.

Conversely, it is plausible that your previous vehicle lacked the low voltage warning functionality, hence potentially resulting in an equivalent battery loss that went unnoticed due to the absence of a warning message feature.

Indeed, your assertion is accurate. I possess a high level of confidence in the novelty of the message in question with regards to the C205.

It is hypothesised that a contemporary automobile may experience a rapid depletion of its battery power upon the initial cessation of engine operation, estimated to be around 200 watts. However, it is expected that this power consumption would thereafter stabilise when the vehicle's different systems deactivate.

The occurrence of battery drainage within a week may indicate either a malfunction in the proper shutdown of some components or a heightened sensitivity of the vehicle to the battery's charge level prior to displaying the aforementioned notice. Has anybody else seen this warning within a short span of time?

It seems that the issue I encountered is similar in nature.

Based on empirical observations, it seems that the vehicle's behaviour may be attributed to a genuine depletion of battery-powered electrons, rather than mere paranoia. Furthermore, the rapid rate at which the battery is being drained is deemed to be unwarranted. It may be inferred that the event has not occurred thereafter.

Have you perused the aforementioned publication, The Post?

The information pertaining to the battery consumption logs? Thank you for your response. I am considering seeking assistance from Mercedes in regards to the observed issue with my vehicle. Specifically, I have noticed that after the car has been stationary on the driveway for a few days, it takes around one hour of driving before the start-stop feature becomes operational.
