The recommended maintenance schedule for the 2018 C-Class Cabriolet includes service intervals at 10,000 miles or 12 months, whichever comes first. Regular maintenance includes oil changes, brake inspections, fluid checks, tire rotations, and multi-point inspections.
To reset the service indicator, turn the ignition to position 1 (do not start the car), use the steering wheel buttons to navigate to the 'Trip' menu, press and hold the 'Call' and 'OK' buttons until the service menu appears, then select 'Full service' and confirm the reset.
Mercedes-Benz recommends using synthetic motor oil with a viscosity of 0W-40, 0W-30, or 5W-40 that meets the MB-Approval 229.5 specification for the 2018 C-Class Cabriolet.
If the convertible top is not opening, check for obstructions, ensure the trunk partition is correctly positioned, and verify that the vehicle is stationary with the parking brake engaged. If the issue persists, inspect the fuse or consult a professional technician.
If the check engine light illuminates, ensure the gas cap is tightly secured. If the light remains on, use a diagnostic tool to check for error codes or visit a Mercedes-Benz service center for a thorough inspection.
To pair your smartphone, enable Bluetooth on your device, navigate to the vehicle's multimedia system, select 'Telephone', then 'Connect Device', and follow the prompts to complete the pairing process.
To replace the key fob battery, remove the mechanical key by sliding the release catch, open the battery compartment, and replace the old battery with a new CR2025 battery, ensuring the correct polarity.
To improve fuel efficiency, maintain proper tire pressure, use recommended motor oil, reduce excess weight, and avoid aggressive driving. Regular maintenance also helps in optimizing fuel economy.
Common causes of squeaky brakes include worn brake pads, glazed surfaces, or debris caught in the braking system. Inspect the brake components and replace or clean them as necessary.
The 2018 C-Class Cabriolet does not have a traditional transmission dipstick. Checking the transmission fluid level typically requires a visit to a Mercedes-Benz service center, where they use specialized tools to measure the fluid level accurately.
