Step-by-Step Guide to Resetting the Coolant Light
If you’re seeing the coolant light illuminated on your Mercedes dashboard, it’s important not to ignore it. The coolant light usually indicates that there may be an issue with the engine’s cooling system, such as low coolant level or a malfunctioning sensor. Fortunately, resetting the coolant light on a Mercedes is a fairly simple process that you can do at home.
To start, make sure the engine is turned off and the key is removed from the ignition. Open the hood of the car and locate the coolant reservoir, which is usually a translucent plastic tank with a cap labeled “coolant.” Carefully remove the cap and check the coolant level.
If the coolant level is low, you will need to add more coolant until it reaches the maximum level line. Once you’ve checked and filled the coolant level, replace the cap securely. Now, you can reset the coolant light by using the onboard computer system.
Insert the key into the ignition and turn it to the “on” position, but do not start the engine. Use the buttons on the steering wheel or console to navigate to the vehicle settings menu. From there, locate the option to reset or clear the coolant light.
Follow the on-screen prompts or refer to your owner’s manual for specific instructions on how to reset the coolant light on your Mercedes model. Once you’ve successfully reset the coolant light, turn off the ignition and start the car to ensure that the light is no longer illuminated. If the coolant light continues to stay on after resetting it, it may be an indication of a more serious issue that requires professional inspection and repair.

Step 2: Open the hood
In order to reset the coolant light in your vehicle, the first step is to open the hood. This may seem like a simple and straightforward task, but it is an important one. By opening the hood, you gain access to the engine compartment and the coolant reservoir, which is where you will find the coolant light sensor.
To open the hood, locate the hood release lever inside the vehicle. This is usually located near the driver’s side footwell or under the steering column. Pull the lever and then go to the front of the vehicle to locate the hood latch.
Release the latch by pushing it to the side or pulling it up, depending on your vehicle’s make and model. Once the latch is released, lift the hood up and secure it with the prop rod or hood support arm. Opening the hood is the first step in the process of resetting the coolant light and allows for further access and troubleshooting.
Now that the hood is open, we can move on to the next step in the process.
Step 3: Locate the coolant reservoir
In order to reset the coolant light in your vehicle, you first need to locate the coolant reservoir. This is where the coolant is stored and circulated throughout the engine to keep it at a safe operating temperature. The coolant reservoir is typically a plastic tank that is either clear or opaque, and it is usually located near the radiator.
In some vehicles, it may be located on the side or front of the engine compartment. To find the coolant reservoir, you can refer to your vehicle’s owner manual for specific instructions or look for any plastic tanks with hoses connected to them. Once you have located the coolant reservoir, you can proceed to the next steps in resetting the coolant light.

Common Issues and Troubleshooting
If you’re a Mercedes owner and you’ve noticed that your coolant light is on, you may be wondering how to reset it. The coolant light usually comes on when the coolant level is low or when there is a problem with the cooling system. To reset the coolant light on a Mercedes, you first need to make sure that the coolant level is correct.
If it’s low, you’ll need to top it up with the appropriate type of coolant. Once the coolant level is correct, you can reset the light by following these steps: Turn on the ignition, but don’t start the engine.
Use the multifunction steering wheel controls to navigate to the vehicle settings menu.
Find the maintenance section and select it. Look for an option to reset the coolant light and select it.
Confirm the reset and then turn off the ignition. After following these steps, the coolant light should be reset and no longer illuminated.
However, if the light continues to come on or if you’re unsure about how to reset it, it’s always best to consult the owner’s manual or take your vehicle to a Mercedes dealership for assistance.
Issue 1: Coolant level is low
“coolant level is low” One common issue that car owners may encounter is a low coolant level. Coolant, also known as antifreeze, is an important component in the car’s cooling system. It helps regulate the engine’s temperature and prevent it from overheating.
So, when the coolant level is low, it can cause several problems and may affect the overall performance of the vehicle. But what causes the coolant level to drop? There could be several reasons why the coolant level is low. One possibility is a leak in the cooling system.
Over time, hoses, fittings, or the radiator itself can develop small cracks or holes, leading to coolant leakage. Another potential cause is a faulty radiator cap. If the cap is not properly sealed, it can allow coolant to escape.
So, what can you do if you notice that your coolant level is low? The first step is to check for any visible signs of leaks. Inspect the radiator, hoses, and fittings for any signs of coolant dripping or pooling. If you can’t find any leaks, it’s a good idea to have a professional mechanic perform a pressure test to identify any hidden leakages.
In some cases, the low coolant level may be due to evaporation over time. If this is the case, you can simply top up the coolant to the recommended level. However, if there is a persistent coolant loss, it is essential to address the issue to avoid potential damage to the engine.
Remember, a low coolant level can lead to engine overheating, which can result in costly repairs. So, it’s crucial to address the issue promptly. If you’re not comfortable troubleshooting the problem yourself, it’s best to take your car to a trusted mechanic who can diagnose and fix the underlying cause of the low coolant level.
Issue 2: Coolant light keeps coming back on
One common issue that many drivers face is the coolant light coming back on in their car. This can be a frustrating problem, as it often indicates that there is an issue with the car’s cooling system. There are a few common reasons why the coolant light may continue to come on, and troubleshooting these issues can help resolve the problem.
One possible cause is that there is a leak in the cooling system, which is causing the coolant level to drop below the minimum level. Another possible reason is that the coolant sensor is faulty and is giving incorrect readings to the car’s computer. Additionally, a malfunctioning thermostat or a clogged radiator can also cause the coolant light to come on.
To troubleshoot these issues, it is recommended to check for any visible leaks in the system and to ensure that the coolant levels are topped up. If there are no obvious leaks, then it may be necessary to have the car inspected by a mechanic to diagnose and fix the issue. By addressing these common issues, drivers can prevent the coolant light from coming back on and ensure that their car’s cooling system is functioning properly.
Issue 3: The coolant light is on but the coolant level is normal
If you notice that the coolant light is on in your vehicle, but the coolant level appears to be normal, there could be a few potential issues at play. One possibility is that there is a faulty sensor or wiring issue that is causing the coolant light to illuminate incorrectly. Another possibility is that there is a problem with the cooling system itself, such as a clogged or blocked radiator or a malfunctioning thermostat.
It’s important to address this issue promptly, as driving with a malfunctioning cooling system can lead to overheating and potential damage to your engine. To troubleshoot the problem, you may want to start by checking the coolant levels again, ensuring that the engine is cool and the vehicle is on level ground. If the levels are indeed normal, you may need to take your car to a mechanic or dealership to have the problem diagnosed and repaired.
