To connect your smartphone via Bluetooth, first ensure your device's Bluetooth is on. Then, navigate to the "Telephone" menu on the COMAND system, select "Connect Device," and choose your phone from the list. Confirm the pairing code on both devices to complete the connection.
Ensure the GPS signal is not obstructed by buildings or tunnels. Check for any updates available for the navigation maps. If the problem persists, reset the COMAND system to factory settings or consult your dealer for further assistance.
Mercedes-Benz recommends changing the engine oil every 10,000 miles or once a year, whichever comes first. Always use the recommended oil type for optimal performance.
To reset the TPMS, go to the "Service" menu on the instrument cluster, select "Tire Pressure," and follow the prompts to reset. Ensure all tires are inflated to the recommended pressure before performing the reset.
Software updates for the COMAND system can be performed at an authorized Mercedes-Benz dealership. Alternatively, if you have a USB update drive, you can insert it into the system and follow the on-screen instructions.
For long-term storage, ensure the fuel tank is full, the tires are inflated to the correct pressure, and the battery is either disconnected or connected to a trickle charger. Consider using a car cover to protect the vehicle from dust and debris.
To replace the cabin air filter, locate the filter housing under the glove compartment. Remove the cover, slide out the old filter, and insert the new one. Ensure it is properly seated before replacing the cover.
First, replace the battery in the key fob. If the issue persists, check for any interference from nearby electronic devices. If the problem continues, consult your dealer as there might be a need to reprogram the system.
To improve fuel efficiency, maintain regular service intervals, ensure tires are properly inflated, reduce excess weight in the vehicle, and drive smoothly by avoiding rapid acceleration and braking.
Common causes include a loose gas cap, faulty oxygen sensor, or a malfunctioning catalytic converter. It's important to have the vehicle diagnosed with an OBD-II scanner to determine the specific cause and address it accordingly.
