Stop Vehicle leaving the engine running in P mode for at least 10 minutes will manually reset this dashboard warning. There are several models that can display this error message, including the C300, GLC300, E300, C200, C43 AMG, C250, and C180.
Do You Know How It Works?
It doesn’t matter what caused the low voltage, the warning light always appears. Depending on the situation, the driver or the car may display this warning light at start up or while driving. Chargers, alternators, or voltage regulators all most likely cause this problem while driving.
When your car is started in the morning after not being used overnight, this warning light may not appear right away. A malfunctioning battery or parasitic power loss can cause this problem if the battery is old or weak. Leaving a motor, a radio, or your headlights on while driving can also present this warning sign.
Cars say to stop the engine, but they leave them running. What is the reason for this?
Here are five reasons
A variety of factors can contribute to this, including:
1. Battery that is not working
Weak batteries are often responsible for this warning. It can be caused by an old or neglected battery. After three years, your Mercedes battery needs to be replaced.
2. Batteries with low current
After installing a new battery, there is the possibility that it is not powerful enough to power your Mercedes. Select an amp-rated battery for your Mercedes to ensure adequate power.
3. Batteries terminals
Securely connecting the terminals and posts of the battery is essential. An improperly connected alternator will prevent your Mercedes battery from charging. It is important to tighten both ends of the linkage at once to ensure a secure connection between the battery terminals.
If you install a new battery, your alternator must recharge it often. The effectiveness of a battery decreases over time if it is not charged regularly.
4. Parasite draining
This error can be caused by parasitic drains in a variety of situations. There is a possibility that the glove box lights may not be turned off properly if a locked door is opened.
5. Faulty alternator
If the “Stop Vehicle Leave Engine Running” error occurs due to a defective alternator, the problem may be related to the alternator. The alternator powers the vehicle’s systems. The device is capable of converting engine power into electrical power. Eventually, a dead battery results from an alternator malfunctioning, which drains the battery constantly.
What To Do When Your Mercedes Stops Running: 5 Tips:
Here are a few solutions you can try:
1. Drive with caution:
If you encounter this, be gentle and careful. Once you have stopped in a safe location, put your vehicle in Park (P). Some situations result in the message saying “Stop Vehicle Shift to P.” instead of “Stop Vehicle Leave Engine Running.”
2. Auto service station
Car maintenance shops can replace your Mercedes battery with the help of trained mechanics. It is necessary for the mechanic to install an additional 12v battery.
3. Take charge of the task
It’s easy to do yourself and you’ll save more than half the cost compared to a dealer with the right tools and battery size.
4. Idle the vehicle for a few seconds
Don’t move your Mercedes-Benz engine until it has been idle for 20 or 30 minutes. This method recharges car batteries. If you’re driving on a main road, you may be able to speed up. Performing this will make car batteries charge faster.
5. Replacement of the battery
In the event that the battery fails to charge, the warning won’t be removed. Another issue may arise, such as a dead battery.
