The trunk switch is located at the bottom of the window lift switch on the driver's door. Pull the button up for more than 3 seconds to automatically open the trunk. You can also open it by pressing the button on the car key. Stand at the rear of the vehicle and perform a kicking motion within the detection range of the sensor under the bumper. You will hear an alarm sound when the trunk opens or closes. Pay attention to the placement of items. "Large items at the bottom, small items on top; heavy items in the front, light items in the back."

Last time I helped my best friend deal with her Mercedes-Benz C200's locked trunk issue, I discovered there are actually three solutions. Everyone knows how to use the trunk button located below the steering wheel's lower left side, right? If it malfunctions, don't panic. There's a keyhole beneath the chrome strip above the license plate – just insert the key and turn it clockwise all the way. The real lifesaver is the emergency release handle in the top-left corner inside the trunk; lift the cover and pull it to open. Friendly reminder: The handle is usually covered by felt fabric – you'll need to feel for the small square cover and pry it open to see it. I recall news reports about children getting trapped in trunks while parents panicked, so it's crucial to familiarize yourself with these emergency mechanisms in advance.

My relative's Mercedes-Benz C200 suddenly couldn't open the trunk one time, leaving us squatting by the roadside trying to figure it out. Actually, there's a physical keyhole hidden at the very bottom of the trunk lid—you have to crouch down to spot the small slit above the license plate frame. Insert the mechanical key and turn it all the way to the right. If it malfunctions in a parking lot, you can also fold down the rear seats to crawl inside; there's a pull handle at the shoulder of the seat that releases it when tugged. From inside, feel for the yellow plastic pull handle on the left side of the interior lining and give it a hard yank. However, Mercedes hides this handle deep—you'll need to peel back some of the left interior lining's felt to reach it properly.

Having run a repair shop for over a decade, I've found that 80% of Mercedes trunk malfunctions are due to electrical control issues. For manually opening a C200's trunk, first locate the metal strip on the car key, pry it open to extract the mechanical key. Crawl under the rear bumper - slightly left of center between the license plate lights there's a hidden access panel. Insert the key until it catches, then forcefully turn it 90 degrees to release the trunk. If the trunk is jammed by objects and won't open, there's a small yellow emergency handle on the inner ceiling lining that can save the day. Mercedes designs these emergency features quite discreetly, but they prove invaluable in critical situations.
