To reset the tire pressure monitoring system, start the vehicle and use the steering wheel controls to navigate to the 'Service' menu on the dashboard. Select 'Tire Pressure' and choose 'Reset'. Confirm the action and drive for a few miles to allow the system to calibrate.
It is recommended to use Mercedes-Benz approved engine oils that meet MB 229.5 or MB 229.51 specifications. Always refer to your owner’s manual for the most accurate information.
To connect your smartphone, activate Bluetooth on your phone and select 'Phone' on the infotainment system. Choose 'Connect Device', select your phone from the list, and confirm the pairing code on both devices.
If the electronic parking brake does not release, ensure the vehicle is in a running state with the driver's seatbelt fastened. Press the brake pedal firmly and try releasing the parking brake again. If the issue persists, consult a Mercedes-Benz service center.
Regular maintenance should be performed every 10,000 miles or once a year, whichever comes first. Always adhere to the service intervals specified in your vehicle's maintenance booklet.
To change the cabin air filter, locate the filter housing under the dashboard on the passenger side. Remove the cover, take out the old filter, and insert the new filter. Ensure the airflow direction matches the arrow on the filter. Reattach the cover securely.
To update the navigation system, insert a USB drive with the latest map data into the USB port. Follow the on-screen prompts on the infotainment display to complete the update. Ensure the vehicle is running during the update process.
Adaptive cruise control may vary speed due to traffic conditions or if the sensors detect a slower vehicle ahead. Ensure the sensors are clean and not obstructed. If the issue persists, have the system inspected by a professional.
To enable the ECO start/stop function, press the ECO button located on the center console. The system will automatically turn off the engine when the vehicle comes to a stop and restart it when you release the brake pedal.
If the key fob battery is low, replace it with a new CR2032 battery. To do this, slide the release switch on the back of the fob, remove the mechanical key, and use it to open the battery compartment. Replace the battery, ensuring the positive side faces up.
