Mercedes-Benz recommends using synthetic 5W-40 motor oil for the 2014 S-Class Sedan. Always check your owner's manual for the most accurate specifications.
To update the navigation system, visit the Mercedes-Benz dealership for the latest map updates. You can also purchase the update online and install it using a USB drive by following the instructions provided with the update package.
If the battery is new and the vehicle is still not starting, check the starter, alternator, and fuses. Additionally, ensure that the battery connections are clean and secure. It may also be a problem with the key fob, so try replacing its battery.
To change the cabin air filter, locate it under the dashboard on the passenger side. Remove the panel and the old filter, then replace it with a new one, ensuring it is oriented correctly according to the airflow direction indicated on the filter.
If the air suspension is not functioning correctly, check for air leaks in the suspension system, inspect the air compressor, and ensure the electrical connections are intact. It may also be necessary to scan for error codes using an OBD-II scanner.
To pair your smartphone, enable Bluetooth on your phone and go to the COMAND system in your car. Select 'Phone', then 'Connect Device'. Choose 'Search for Phone' and follow the prompts to pair your phone by entering the passcode if required.
Reduced fuel efficiency can be caused by several factors, including underinflated tires, dirty air filters, or worn spark plugs. It is also advisable to check for any diagnostic trouble codes that may indicate engine performance issues.
To enhance ride comfort, ensure that your tires are properly inflated and aligned. Regularly check the condition of the suspension components, including shocks and struts, and replace them as necessary.
Regular maintenance includes oil and filter changes every 10,000 miles, checking and topping off fluid levels, inspecting brakes, and rotating tires every 5,000 to 7,000 miles. Additionally, replace the air filter every 15,000 miles and the cabin filter every 20,000 miles.
