Mercedes E 400 Workshop Manuals and Repair Manuals

To change the oil in your Mercedes E 400, start by locating the oil drain plug underneath the engine, and use a wrench to remove it. Allow the old oil to drain completely, and then replace the drain plug tightly. Next, locate the oil filter and use an oil filter wrench to remove it. Before installing the new oil filter, make sure to lubricate the rubber gasket with fresh oil. Finally, refill the engine with the recommended amount of new oil, and check the oil level using the dipstick.

To check the tire pressure on your Mercedes E 400, start by ensuring the tires are cold (not driven for at least an hour). Locate the tire pressure monitoring system (TPMS) reset button, usually located in the glove compartment or on the center console. Press and hold the TPMS reset button until the tire pressure monitoring light blinks three times. Then, release the button and the system will enter the tire pressure monitoring mode. Check each tire's pressure using a reliable tire pressure gauge and adjust as needed. Once all tires are properly inflated, press and hold the TPMS reset button again until the light stops blinking, indicating the tire pressure has been reset.

To jump-start your Mercedes E 400, you will need a set of jumper cables and a functioning vehicle with a similar voltage battery. Park the assisting vehicle close enough to your Mercedes E 400 so that the jumper cables can reach both batteries comfortably. Ensure both vehicles are turned off, and connect the red clamp of the jumper cables to the positive terminal of the dead battery and the positive terminal of the assisting vehicle's battery. Then, connect the black clamp to the negative terminal of the assisting vehicle's battery, and the other black clamp to a solid, unpainted metal surface on your Mercedes E 400 away from the battery. Start the assisting vehicle and let it run for a few minutes, then attempt to start your Mercedes E 400. Once started, let both vehicles run for a few more minutes before disconnecting the jumper cables in the reverse order.

To replace a headlight bulb in your Mercedes E 400, first, open the hood and locate the back of the headlight assembly. Disconnect the electrical connector from the bulb by gently pressing the release tab and pulling it away. Next, remove the bulb retaining clip by releasing the clips or screws holding it in place. Carefully remove the old bulb and replace it with a new one, making sure not to touch the glass portion. Reinstall the retaining clip and reconnect the electrical connector, then test the new bulb to ensure it is working properly before closing the hood.

To replace the air filter in your Mercedes E 400, first, locate the air filter housing, which is typically located near the engine. Open the housing by removing any clips, screws, or latches. Take note of the filter orientation before removing the old air filter to ensure proper installation of the new one. Remove the old filter and clean the housing if necessary. Install the new air filter, ensuring it is properly aligned and seated in the housing. Close the housing securely, making sure all clips, screws, or latches are properly fastened. It is recommended to check and replace the air filter at regular intervals for optimal engine performance and fuel efficiency.

To replace the cabin air filter in your Mercedes E 400, start by locating the filter housing, which is typically located behind the glove compartment or under the hood near the windshield. Open the housing by removing any clips or screws holding it in place. Carefully remove the old cabin air filter and clean the filter housing if necessary. Install the new cabin air filter, ensuring it is properly aligned with the arrows indicating the airflow direction. Close the housing by reattaching any clips or screws, and test the air conditioning and heating system to ensure proper airflow.

To replace the spark plugs in your Mercedes E 400, start by ensuring the engine is cool and the ignition is turned off. Locate the spark plug wires or ignition coils, depending on your specific engine model. Carefully disconnect the wires or coils from the spark plugs, taking note of their original order. Use a spark plug socket and a ratchet to remove the old spark plugs from the engine cylinder head. Check the gap on the new spark plugs using a spark plug gap tool, and adjust if necessary. Install the new spark plugs by hand, then tighten them with a torque wrench to the specifications provided in your vehicle's owner's manual.

To replace the windshield wipers on your Mercedes E 400, start by lifting the wiper arm away from the windshield. Locate the small tab or release mechanism on the wiper blade assembly, and press or slide it to release the blade from the wiper arm. Remove the old wiper blade and install the new one by aligning the adapter or clips with the wiper arm. Ensure the new blade is securely attached, then carefully lower the wiper arm back onto the windshield. Test the new wipers to ensure proper operation and clear visibility.

To reset the service indicator on your Mercedes E 400, follow these steps: Start with the ignition turned off. Press and hold the trip reset button while turning the ignition on (position 1).

When you turn the ignition back on, the service indicator should no longer be displayed. If the indicator persists, it may require further diagnosis from a qualified technician.

The frequency of brake pad replacement on a Mercedes E 400 can vary depending on driving habits, conditions, and overall wear. As a general guideline, it is recommended to inspect the brake pads every 10,000 miles and replace them if the thickness is less than 3mm. However, it is important to also pay attention to any warning signs such as squeaking or grinding noises, reduced braking performance, or the brake pad wear indicator light illuminating on the dashboard. If any of these signs are present, immediate replacement is necessary to ensure safe braking operation.

The recommended tire pressure for your Mercedes E 400 can vary depending on the tire size, load conditions, and driving preferences. To find the specific recommendations, refer to the tire information placard located on the driver's side door jamb or the owner's manual. The placard will provide the recommended tire pressure for both the front and rear tires, usually specified in PSI (pounds per square inch). It is essential to regularly check and maintain the tire pressure within the recommended range for optimal safety, fuel efficiency, and tire longevity.

For your Mercedes E 400, it is recommended to use an ethylene glycol-based coolant that meets the specifications outlined in your vehicle's owner's manual. This type of coolant provides effective protection against freezing and boiling, as well as corrosion and cavitation. It is important to never mix different types of coolant, as this can lead to damage to the cooling system. If unsure, it is best to consult the owner's manual or contact a certified Mercedes technician for further guidance.

It is crucial to use the correct engine oil for your Mercedes E 400 to ensure optimum performance and longevity of the engine. Refer to your vehicle's owner's manual for the recommended engine oil specifications, including viscosity grade and quality standards. Typically, Mercedes-Benz recommends using synthetic engine oil with the appropriate viscosity rating for your specific engine model. Using the wrong type of oil or not adhering to the manufacturer's recommendations can lead to engine damage and potential warranty issues.
