Learn how to check a Mercedes-Benz vehicle’s brake, coolant, and windshield washer fluid. It is recommended to check fluids and top-of-the-level before each road trip. Remember that many 2015 and newer Mercedes-Benz use electric steering, so your vehicle may not have a power steering pump.
Check Brake Fluid Level
- Open the driver’s door and pull the hood release under the dashboard. Then go to the front of the vehicle and unlock the hood latch. Pull the hood up and use the hood strut to hold the hood.
- Locate the brake fluid reservoir on the driver’s side of the engine compartment. To check the fluid level, shake the reservoir a little to see where the fluid lines. To add brake fluid, open the cap by turning it counterclockwise. Close the cap by turning it clockwise. Use the brake fluid recommended by the vehicle’s manufacturer and ensure that it is from a sealed container.
Check / Add Windshield Washer Fluid
- Locate the windshield washing tank on the driver’s side of the engine compartment. To add fluid, open the blue cap by simply pulling it out. Close the cap by pressing it back to the tank.
Check Engine Coolant Level
- Allow the engine to cool down.
- Locate the coolant reservoir on the passenger side of the engine compartment. Remove the cap on the coolant reservoir to check and add fluid by turning it counterclockwise. Close the cap when done adding coolant.
