Topping up coolant on Mercedes c280?

To top up the coolant on a Mercedes C280, first ensure the engine is cool to avoid burns. Open the hood and locate the coolant reservoir, which is usually a translucent tank marked with minimum and maximum levels. Carefully remove the cap, and add the appropriate coolant mixture (typically a mix of antifreeze and water) until it reaches the maximum level. Replace the cap securely and check for any leaks after topping up.
