There are three methods to open the trunk of the CS5, detailed as follows: 1. Mechanical Key Opening: Insert the key into the trunk lock cylinder to open or close the trunk. This is the mechanical method, harking back to the era when car trunks first appeared and relied solely on mechanical keys. Nowadays, this method is considered quite cumbersome and has largely been phased out. 2. Remote Key Direct Opening: Using the remote key to open the car trunk is the most straightforward and simplest method. It's quite easy to use—simply press the trunk opening button on the remote key to open it. 3. Pressing the Unlock Button Directly: Some car models may not have a dedicated trunk opening button on the remote key. In such cases, pressing the unlock button will also release the trunk lock. 4. Smart Key + Trunk Switch: Additionally, some models come equipped with a smart key. As long as the remote key is within a certain range (usually about 1 meter), pressing the switch on the trunk will directly open it.

As an experienced driver who has driven many cars, opening the trunk of the CS55 is actually quite simple. Normally, I just press the trunk button on the key fob for two seconds, and it pops open automatically. If the key isn’t handy, simply walk to the rear of the car and press the physical button above the license plate frame—just make sure the key is in your pocket for it to detect. There’s also a mechanical lever under the driver’s seat; just bend down and pull it to open. Higher-end models are even more advanced—just wave your foot under the rear bumper with the key on you, and the trunk opens by itself. The most practical feature is the kick-to-open function when your hands are full, but remember to move swiftly and step back after the motion to avoid getting hit by the tailgate. Normally, pressing the tailgate button won’t open it when the car is locked—you’ll need to unlock it with the remote first.

As a working mom, I open the CS55's trunk several times daily for school runs. The most convenient method is using the key fob—just long-press the trunk icon button to pre-open it in parking lots. When my hands are full with shopping bags, a quick foot sweep under the rear bumper triggers a beep and automatic opening—this sensor feature is incredibly handy. For base models without kick sensors, there's a recessed button lower-center on the trunk lid. Remember to keep the key nearby—once I left it in the living room and couldn't open it. There's also an electronic button on the driver's door panel, but I rarely use it since walking around isn't much trouble.

Last time I drove my friend's CS55, I discovered four ways to open the trunk: 1) Press and hold the trunk button on the remote key for three seconds; 2) Directly press the black button in the middle of the trunk lid; 3) Use the manual lever near the driver's left foot position; 4) For models with a smart key, swipe your foot under the rear bumper to activate the sensor. The mechanical button is located slightly below the center of the tailgate, with anti-slip texture for easy identification. Simply press the button when unlocked; if locked, you need to unlock first. Note that when using the foot sensor, the motion should be smooth—quickly swipe your foot horizontally near the rear radar area. Successful activation will be indicated by flashing hazard lights. Base models don't have the foot-sensing feature, but the other methods are universally applicable.

When I first got my CS55, I spent quite some time figuring out the trunk. Now I've got it all figured out. The mechanical method is the easiest to find—just press the round button in the middle of the rear license plate lights to open it. The remote key is even more convenient: within five meters, press and hold the button with the trunk icon for three seconds, and the tailgate will pop open automatically. The luxury version supports foot-sensing—just stand at the rear with the key and wave your foot under the bumper for half a second to trigger it. The in-car switch is located near the driver's left knee, a square button with a rear car icon. If none of these methods work, first check if the child lock was accidentally activated or try using the mechanical key in the emergency hole on the tailgate. In practice, the foot-sensing method has the highest success rate, but keep your distance from the bumper on rainy days to avoid accidental triggers.

Since I often help people move, I pay special attention to trunk opening. The CS55's standard operation is to use the key fob—press and hold the button with the car icon for three seconds. In practice, I recommend using the physical button instead, located right below the license plate frame. A simple press instantly unlocks the tailgate. The hands-free sensor on higher trims is the most impressive feature—just swipe your foot under the middle of the trunk to open it automatically, which is especially handy when carrying large cardboard boxes. Note that the sensor area is at the center of the rear bumper, and your leg should sweep sideways, not kick up and down. If it doesn’t respond, you might be standing too close or the key might be blocked in your bag—try hanging it on your waist for faster recognition. For a temporary manual override, pull the metal lever near the driver’s seat, but don’t yank too hard to avoid damaging the cable.
