The Mercedes has long been known for its smooth ride and quality construction. One of the key features is the Mercedes steering system. The Mercedes uses a hydraulic-powered system to make turning the wheels easier. When you turn the steering wheel, the fluid is sent to a pump that builds pressure and helps to push the steering gear. The steering gear, in turn, will move the steering arms that are connected to the wheels, making them move the Mercedes in the direction you are intending.
Open the bonnet to access the engine compartment. The power steering reservoir is located at the top of the engine to the bottom right of the air cleaner.
Unscrew the cap and pull it toward you. There will be a dipstick attached to the cap.
Wipe the dipstick off with a clean towel.
Stick the dipstick back into the reservoir. Tighten it down all the way.
Unscrew the dipstick and pull it back out. Notice where the fluid stops on the dipstick. The dipstick is marked with level indicators and will specify how much fluid is in the reservoir.
Insert a funnel into the reservoir if the fluid level is low.
Pour in 1/4 of a quart and continue checking till the level is at the Full mark.
Consult your owner's manual to ensure you purchase the proper type of power steering fluid. Inspect for any leaks around the reservoir and hoses after filling.
Do not check while the engine is hot. This may result in burns as the components are hot to the touch.
