4. If the coolant level is low, add coolant to the reservoir until it reaches the “MAX” mark.
5. Close the hood and start the engine.
6. The coolant light should turn off after a few seconds.

If the coolant light does not turn off after you have reset it, there may be a problem with your coolant system. You should take your Mercedes-Benz to a qualified Mercedes-Benz dealer or repair shop for diagnosis and repair.

What to do if the coolant light is still on after resetting it?

If the coolant light on your Mercedes-Benz is still on after you have reset it, there may be a problem with your coolant system. You should take your Mercedes-Benz to a qualified Mercedes-Benz dealer or repair shop for diagnosis and repair.

Here are some possible causes of a coolant light that stays on:

• Low coolant level: The most common cause of a coolant light is a low coolant level. If the coolant level is low, it can cause the engine to overheat.
• Coolant leak: A coolant leak can also cause the coolant level to drop and the coolant light to come on.
• Faulty coolant sensor: The coolant sensor is a sensor that detects the coolant level in the engine. If the coolant sensor is faulty, it can cause the coolant light to come on even if the coolant level is normal.
• Faulty coolant pump: The coolant pump is responsible for circulating coolant through the engine. If the coolant pump is faulty, it can cause the coolant level to drop and the coolant light to come on.

If you have a coolant light that stays on, it’s important to have it diagnosed and repaired as soon as possible. A low coolant level or a coolant leak can damage your engine, so it’s important to take action to prevent further damage.

Here are some tips for preventing coolant light problems:

• Check the coolant level regularly and add coolant as needed.
• Look for signs of coolant leaks, such as puddles of coolant under your car or a sweet-smelling liquid on the engine.
• Have your coolant system checked and serviced regularly.

By following these tips, you can help prevent coolant light problems and keep your Mercedes-Benz running smoothly.
