A "Check Engine" light can be triggered by various issues such as a loose gas cap, faulty oxygen sensor, or issues with the catalytic converter. It's best to have the vehicle checked with an OBD-II scanner to determine the specific error code.
To pair your phone, activate Bluetooth on your phone and make sure it's discoverable. On the car's COMAND system, select "Phone" then "Connect Device". Choose your phone from the list and enter the passcode if prompted.
First, try replacing the battery in the key fob. If it still doesn't work, try reprogramming the key or consult a Mercedes-Benz dealer as it might be a more complex issue.
To improve fuel efficiency, ensure regular maintenance like oil changes and air filter replacements. Keep tires properly inflated, reduce excess weight in the car, and avoid aggressive driving.
The recommended tire pressure for the 2012 S-Class is typically 32 PSI for the front tires and 35 PSI for the rear tires. However, you should check the sticker on the driver's side door for specific information for your model.
Air suspension issues can be due to a leak in the air springs, a faulty air compressor, or a malfunctioning height sensor. A diagnostic check is necessary to pinpoint the exact problem.
To replace the cabin air filter, open the glove compartment, remove the damper arm, and lower the compartment fully. Remove the cover of the filter housing, take out the old filter, and insert the new one. Replace the cover and reassemble the glove compartment.
