What To Do IF Stop Vehicle Leave Engine Running?

Imagine you are driving a car and when you stop your vehicle and come out of it, you notice that your vehicle left the engine running. Now, what to do?

Mercedes Benz vehicles that display the warning “Stop Vehicle Leave Engine Running” on the dashboard almost always have a battery issue. This occurs for a variety of reasons. To determine the root of your issue and how to fix it, read the article below.

Reasons For Stopping A Car With The Engine Running

If the message “Stop Vehicle Leave Engine Running” shows on the dashboard of your Mercedes Benz car, your car battery is malfunctioning. The following are some of the causes of this. We’ll briefly go through each of these reasons below.

Use the Autel Scanner MaxiCOM MK808 Bidirectional Diagnostic Tool to assist in identifying the precise problem. It is a straightforward diagnostic scan tool that makes it simple to identify the precise origin of thousands of error codes.

1. Keeping The Lights On Too Long

One of the causes of a failing automobile battery is leaving the lights on for too long. It frequently discharges the backup battery. There may be energy loss when the automobile battery powers the headlights. This can be resolved by using a convenient portable jump starter, such as the Autowit SuperCap 2 Portable Car Jump Starter, to jumpstart the battery.

However, if you keep the car lights on for an extended period of time, your car battery’s life will probably be shortened.

2. Insect Drains

A parasitic drain brought on by a variety of circumstances might also cause the “Stop Vehicle Leave Engine Running” error. It can be due to glove box lights that do not properly switch off even when the door is closed. The headlights, underhood, and trunk lights of your automobile may all experience the same problem.

3. Unreliable Voltage Regulator

It’s possible that your Mercedes Benz has a defective voltage regulator if you ever see the warning “Stop Vehicle Leave Engine Running.” The battery will no longer be able to charge if the voltage regulator in your automobile burns out. The battery will eventually run out of power due to this.

The voltage regulator makes sure that the automotive battery receives efficient, stable charging voltage and power. It is also in charge of giving other electrical components enough voltage and power.

4. Use Of Accessories In Excess

If you have too many electronics permanently connected to your car’s auxiliary outlets, you can eventually run into a dead battery. An illustration of this would be if there were five of you in the car and you were all charging your iPhones at the same time. To accomplish this, a USB extension port is used.

Although the automobile radio is also on, it is not a good idea to use it, especially when traveling small distances. Your smartphones or other electronic devices won’t charge as quickly. Additionally, your car’s battery is being wasted. Even worse, sooner or later, the “Stop Vehicle Leave Engine Running” warning light can illuminate.

5. Battery Cannot Hold A Charge Anymore

If your Mercedes Benz’s dashboard displays the “Stop Vehicle Leave Engine Running” warning, the battery is probably the source of the issue. Your car’s other components might all be in good shape. Perhaps the only problem is the car battery itself.

Verify the main battery in your automobile. Try recharging it to see if it will still work before buying a new one. For all you know, you might still be able to use it and won’t need to purchase a new one.

What To Do IF Stop Vehicle Leave Engine Running?

These are the following ways which can save you from the engine running:

1. As You Stop, Drive Carefully And Slowly

If you come across this, drive cautiously and slowly while pulling over to the side. Make sure you are stopping in a secure location. After then, go to P or Park Mode.

Because of this, the notice may occasionally read “Stop Vehicle Shift to P Leave Engine Running” rather than just “Stop Vehicle Leave Engine Running.” In this method, you won’t forget to switch to park mode.

2. Turn Off The AC And All Of The Lights

The next step is to switch off all of the lights, the air conditioner, the radio, and any other devices that draw power from the vehicle’s battery. But keep the car’s engine running.


3. Allow The Vehicle To Idle For 20–30 Minutes

Give your Mercedes Benz between 20 and 30 minutes to idle. This will enable the vehicle’s battery to recharge. You can eventually travel down the highway, where you can drive the car quickly if you have the opportunity. In this manner, the automobile battery would also charge faster.

4. If The Warning Does Not Go Away, Replace The Car Battery

The battery isn’t charging if the warning doesn’t go away after a while. The automobile battery may need to be replaced, or there may be other issues that prevent it from charging.
