First, replace the battery in the key fob. If the problem persists, try re-synchronizing the key by inserting it into the ignition and starting the car. If it still doesn't work, consult your dealership.
First, ensure the vehicle is on a flat surface and apply the parking brake. Locate the spare tire, jack, and lug wrench. Loosen the lug nuts, jack up the vehicle, remove the lug nuts and tire, mount the spare tire, and tighten the lug nuts in a star pattern. Lower the vehicle and ensure all lug nuts are fully tightened.

The recommended tire pressure is typically 32 PSI for the front tires and 35 PSI for the rear tires, but it's best to check the sticker located on the driver’s side door jamb for specific information.
A burning smell can be caused by a variety of issues including oil leaks, debris trapped in the exhaust, or worn-out brakes. It's advisable to have a professional inspection to diagnose and rectify the issue.
The 2018 C-Class typically has a sealed transmission, and checking the fluid level should be done by a professional. If you suspect a transmission issue, it's best to visit a Mercedes-Benz service center.
Follow the Mercedes-Benz Service A and Service B schedules, which generally include oil changes, brake inspections, fluid level checks, and other necessary maintenance every 10,000 miles or once a year, alternating between Service A and B.
