To reset the service indicator, turn the ignition to position 1. Use the steering wheel buttons to scroll to the "Service" menu. Press and hold the reset button until a confirmation message appears. Release and then press the reset button again to confirm.
The 2012 Mercedes-Benz R-Class typically requires synthetic motor oil with a viscosity of 5W-40. Always refer to the owner's manual for confirmation and ensure the oil meets Mercedes-Benz specifications.
Check for error messages on the dashboard, inspect the air compressor and air lines for leaks, and ensure the fuse for the air suspension system is intact. If problems persist, consult a certified Mercedes-Benz technician.
Park the vehicle on a level surface, engage the parking brake, and place wheel chocks behind the wheels. Use the jack to raise the car, remove the lug nuts, and replace the flat tire with the spare. Tighten the lug nuts in a star pattern.
Press the small button to release the key from the fob. Use a small flathead screwdriver to open the key fob casing. Replace the old battery with a new CR2025 battery, ensuring the positive side faces up. Snap the cover back into place.
Brake squeaking can be caused by worn brake pads, glazed rotors, or accumulated brake dust. Consider cleaning the brake components and, if necessary, replacing the pads or rotors to resolve the issue.
Activate Bluetooth on your phone and set it to discoverable. In the vehicle, access the Bluetooth menu via the COMAND system, select "Add Device," and choose your phone from the list. Confirm the pairing code on both devices.
At 60,000 miles, perform an oil change, replace the air and cabin filters, check and replace the spark plugs if necessary, inspect the brakes, and ensure all fluids are topped up and clean.
Ensure regular maintenance, including timely oil changes and air filter replacements. Maintain proper tire pressure, reduce excess weight, and use cruise control on highways to improve fuel efficiency.
Check for any obvious issues such as a loose gas cap. If the light remains on, use an OBD-II scanner to read the error codes or take the vehicle to a professional to diagnose and address the underlying issue.
