To pair your smartphone with the Bluetooth system, first ensure that your phone's Bluetooth is turned on. Navigate to the 'Telephone' menu on the COMAND system, select 'Connect Device', and choose 'Search for Phones'. Once your phone appears on the screen, select it and confirm the pairing request on your phone. Enter the passkey if prompted.
Mercedes-Benz recommends using synthetic motor oil that meets MB 229.5 or MB 229.51 specifications. It is important to check your owner's manual for the exact type and viscosity suitable for your vehicle's engine.
To reset the tire pressure monitoring system, ensure that all tires are properly inflated. Then, navigate to the 'Service' menu using the steering wheel controls and select 'Tire Pressure'. Follow the prompts to confirm the reset.
If the keyless entry system stops working, first check the batteries in your key fob and replace them if necessary. If the issue persists, try re-synchronizing the key by inserting it into the ignition and starting the car. If neither step resolves the problem, consult a Mercedes-Benz service center.
The air suspension system should be inspected during regular maintenance intervals, typically every 10,000 miles or once a year. However, if you notice any changes in ride quality or handling, have it checked immediately.
To update the navigation system maps, you can purchase the latest map update from the Mercedes-Benz website or a dealership. Insert the update USB into the vehicle's USB port and follow the on-screen instructions to complete the update.
If the check engine light illuminates, first ensure that the gas cap is properly tightened, as a loose cap can trigger the light. If the light remains on, use an OBD-II scanner to check for diagnostic trouble codes or visit a certified mechanic for a thorough diagnosis.
If the electronic trunk release fails, you can manually open the trunk using the mechanical key. Slide the release lever on the key fob to access the mechanical key, then insert it into the lock cylinder located near the license plate and turn it to open the trunk.
The cabin air filter should be replaced approximately every 15,000 to 20,000 miles or once a year, depending on driving conditions. If you notice reduced airflow or unusual odors, consider replacing it sooner.
To improve fuel efficiency, maintain proper tire pressure, follow recommended service intervals, and drive smoothly by avoiding rapid accelerations and decelerations. Additionally, removing unnecessary weight and using the ECO mode can help reduce fuel consumption.
