There are multiple dashboard indicator lights in your Mercedes-Benz vehicle to warn you to probable problems in the different systems that make up the car’s infrastructure. The check engine light is one of the most important indicators to keep an eye on. When this light illuminates, it might indicate that there is an issue with the fuel injection system, the engine management system, the ignition system, the exhaust system, or the fuel system, which could send the engine into emergency mode. If this occurs, kindly seek assistance from your neighborhood Mercedes Benz service center.
Additional Meanings for the Warning Lights.
Coolant light
The Coolant Light is another critical indication. A defective temperature gauge or a low coolant level might cause this light to come on. The extreme temperatures that may follow from running an engine with insufficient coolant can be catastrophic, and the engine may be permanently damaged as a consequence.
Wheel Pressure Warning Lamp
A number of your tires may be underinflated if indeed the Wheel Pressure Light turns on. It’s important to check each tire’s tire pressure information on your dashboard.
Battery Light
The Battery Light’s job is to alert you when the battery is running low on power. Alternator failure or a problem with the vehicle’s electronics are two possibilities.
Brake Wear Light
You’ll know whether your brake pads and rotors need to be changed when the Brake Wear warning light comes on. A Mercedes Benz Service Department should be contacted immediately if this light turns on.
The airbag light
The Airbag Light will come on if there is a problem with the Supplemental Restraint System (SRS). A malfunction in this system might prevent an airbag from deploying in the event of an accident, therefore we urge you to get your car checked out as soon as you can.
Steering Wheel Light
There is a warning tone associated with the Steering Wheel light, which follows next. Your vehicle’s power steering assistance is faulty, and you’ll be aware of this since it will take more effort to steer.
Bulb Alert Light
You’ll also see a Bulb Alert light on your dash. Dimming or total failure may be detected in this way. It is possible that this light will be accompanied by a message that identifies which light is out.
Automatic Locking Brake Mechanism (ABS) Light
The Anti-Lock Brake System and maybe other connected systems are deactivated, according to the ABS Light, which is the last indicator. With or without the Anti-Lock Brake System, you may slow down and come to a full stop as normal.
Other Common Mercedes Warning Lights
The Fuel Light, for example, is one of the most often observed lights on the dashboard. In most cases, the presence of this light indicates a lack of petrol. The fuel pressure in the system may be too low, resulting in a potential petrol leak if you detect it even after you’ve topped out your tank with fuel.
When a car is in drive and traveling at a speed greater than 15 mph, the Seat Belt Monitor caution light alerts the motorist and front passenger when the seat belts are not secured.
Sometimes it’s easy to overlook the fact that the parking brake is still engaged. That’s why your Mercedes-Benz includes a parking brake light that tells you to remove the parking brake before starting the vehicle.
You may also notice a few more lights on your dashboard depending on the type of Mercedes-Benz you possess.
The owner’s handbook that came with your Mercedes-Benz should include a list of all of these lights. These lights should be paid attention to as when they turn on since they might save you money and time, and most critically, keep you safe from a breakdown.

Potential Causes and Solutions
Battery Reconnection Issue: After replacing the thermostat, if the battery was not reconnected properly, it could lead to starting issues.
Solution: Double-check the battery connections. Ensure the terminals are clean, properly connected, and tight.
Electronic System Reset Needed: Modern vehicles like the Mercedes W205 have complex electronic systems. Disconnecting the battery can sometimes require a system reset.
Solution: Try a simple reset by leaving the battery disconnected for about 30 minutes, then reconnecting it.
Error Codes and Sensor Issues: Replacing the thermostat might have inadvertently affected sensors or caused error codes in the electronic control unit (ECU).
Solution: Use an OBD-II scanner to check for any error codes. This can also be done at a service center.
Thermostat Installation Error: If the thermostat was not installed correctly, it could lead to issues.
Solution: Revisit the installation process, ensuring everything is correctly fitted and there are no leaks.
Fuse and Relay Check: Sometimes, the act of disconnecting the battery or working around the engine can disturb fuses or relays.
Solution: Check the fuse box and relays related to the starting system and replace any that are blown or damaged.
Engine Ground Connection: A poor ground connection can lead to starting issues.
Solution: Inspect and clean the engine ground connections.
I hope this helps! Otherwise its best to take to a qualified mechanic!
