To operate the convertible roof, ensure the vehicle is stationary or moving at a low speed. Locate the convertible top control switch on the center console and press it forward to open or pull it backward to close. The process will complete automatically.
The recommended maintenance schedule includes regular checks every 10,000 miles or 12 months, whichever comes first. Key services include oil changes, brake inspections, tire rotations, and fluid level checks. Refer to the owner's manual for a detailed schedule.
If you're experiencing Bluetooth issues, try restarting your phone and the car's infotainment system. Ensure both devices are updated to the latest software. If problems persist, delete the Bluetooth profile and reconnect.
It is recommended to use high-performance summer or all-season tires that fit the OEM specifications: 225/45R18 for the front and 245/40R18 for the rear. Always consult the vehicle's manual or a dealer for specific brand and model recommendations.
To reset the service indicator, turn on the ignition without starting the engine. Use the steering wheel controls to navigate to the 'Trip' menu. Press and hold the call and OK buttons simultaneously until the service menu appears. Select 'Full Service' and confirm the reset.
First, check for any obstructions or debris in the roof mechanism. If clear, try resetting the system by turning the ignition off and back on. If the issue persists, consult a Mercedes-Benz service center as it might require professional repair.
To improve fuel efficiency, maintain regular service intervals, check tire pressure monthly, use cruise control on highways, and avoid rapid acceleration. Additionally, removing unnecessary weight and using the ECO driving mode can help.
To replace the wiper blades, lift the wiper arm away from the windshield. Press the release tab on the blade and slide it off the arm. Align the new blade with the arm hook and push it until it clicks into place. Lower the wiper arm gently back onto the windshield.
The emergency trunk release is located inside the trunk. If you need to access it from inside the car, fold down the rear seats and locate the glow-in-the-dark handle on the trunk lid interior. Pull the handle to open the trunk.
Start by checking the air conditioning refrigerant level and the cabin air filter for any blockages. Ensure the AC system is set to the correct temperature settings. If the problem continues, have the system inspected by a certified technician for potential leaks or compressor issues.
