To reset the service indicator, turn on the ignition without starting the car. Use the steering wheel buttons to navigate to the "Service" menu option. Hold the "OK" button until the service menu appears, then select "Reset" and confirm by pressing "OK" again.
Use synthetic motor oil that meets Mercedes-Benz specification MB 229.5 or MB 229.51, typically SAE 5W-30 or 5W-40. Always refer to the owner's manual for the recommended oil specification.
To update the navigation system, visit the Mercedes-Benz navigation update website, download the latest map data onto a USB drive, and insert it into the vehicle's USB port. Follow the on-screen instructions to complete the update.
First, check the battery in your key fob and replace it if necessary. If the problem persists, try re-synchronizing the key by holding it next to the driver's side door handle. If these steps don't work, consult a Mercedes-Benz dealer.
Activate Bluetooth on your smartphone and on the car's multimedia system. Navigate to the "Phone" menu in the car, select "Connect new device," and choose your phone from the list. Confirm the pairing code on both devices to complete the process.
The recommended tire pressure for the E-Class Coupe 2021 can vary based on the tire size and load conditions. Generally, it should be around 36 psi for the front and 39 psi for the rear tires. Always refer to the sticker inside the driver's door for exact specifications.
The ECO start/stop function is activated by default. If it's not active, press the ECO button on the center console. This feature automatically turns off the engine when the vehicle comes to a stop and restarts it when you release the brake pedal.
Check the battery connections and ensure the battery has a sufficient charge. Verify that the car is in "Park" or "Neutral" and that the brake pedal is fully pressed. If the issue persists, it may require professional diagnostics from a Mercedes-Benz service center.
Use the seat adjustment controls located on the door panel to adjust the seat position, backrest angle, and headrest height. For additional comfort, activate the lumbar support and seat heating options if available.
Software updates are typically available through the Mercedes me connect app or directly via the vehicle's infotainment system. Connect the car to a stable Wi-Fi network and follow the prompts on the screen to download and install any available updates.
