The trunk switch for the BMW 3 Series is located on the center console and the remote control. Alternatively, you can press the trunk switch on the remote control. More details about the BMW 3 Series are as follows: 1. Exterior dimensions: The standard wheelbase version measures 4719mm in length, 1827mm in width, and 1459mm in height, with a wheelbase of 2851mm. The long wheelbase version measures 4829mm in length, 1827mm in width, and 1463mm in height, with a wheelbase of 2961mm. 2. Configuration: The 2021 model comes standard with keyless entry on all models except the 320, and also offers an optional comfort package, which includes a sensor-activated trunk and four-way electric lumbar adjustment for the seats. Additionally, the standard features on the 320 model, such as rearview camera, automatic parking, and track reverse, have been changed to optional configurations.

I remember helping a friend find the trunk switch for this car, and actually there are several ways to open it. Let me start with the most obvious one: There's a button near the driver's left foot, just look down and you'll see it with a trunk icon on it. You can also open it with the car key—just press and hold the round button in the middle for three seconds. This generation of BMW also has a cool hands-free feature: stand behind the trunk with the key, swipe your foot under the bumper, and the trunk will open automatically. The mechanical switch below the rear window is still there—just lift the small groove to find the button. By the way, a reminder: for the hands-free trunk opening, make sure the key is within 1 meter, and avoid wet shoe soles on rainy days to prevent malfunctions. Also, be careful not to accidentally press the key button while washing the car—I've seen cases where the trunk opened automatically and soaked the washing tools.

As a 3 Series owner, I use this feature every day. The trunk switches are quite ergonomically placed. With the doors unlocked, simply press the indentation in the middle of the trunk lid to pop it open. The car key has three buttons, right? Hold down the bottom one marked with the trunk icon to open it. There's also a physical switch on the left floor near the driver's seat, by the knee area next to the door. The most special feature of this generation is the hands-free opening, which is super convenient when wearing a skirt or carrying items in both hands. Just keep the key in your pocket and sweep your foot under the rear of the car—the lights will flash twice, and it will open. Note that the sensor area is 20 cm directly below the emblem, so don't kick the bumper as it won't work. If you've applied a thick paint protection film, it might reduce sensitivity, so stand closer when operating.

What grade of engine oil is suitable for the 1.5T Ford Kuga?

According to Ford's official recommendation, the Kuga 1.5T requires 5W-20 engine oil. The original factory oil is a light green oil produced by Castrol. You can refer to the vehicle's user manual, which provides detailed instructions. Follow the manual's guidelines when adding engine oil. Precautions for using engine oil are as follows: 1. First and foremost, ensure the oil is genuine. 2. Using counterfeit or substandard oil not only fails to protect the engine but can also damage it. 3. Since the Kuga 1.5T is equipped with a turbocharged engine, and the turbo operates under high temperature and high-speed conditions, failing to use fully synthetic oil will prevent effective engine protection, potentially causing damage and reducing the engine's lifespan.

What are the correct steps for hill starting?

The correct steps for hill starting: 1. On the slope, pull up the handbrake, press the clutch with your left foot, and shift the car into first gear; 2. Slowly and gently lift your left foot to release the clutch while pressing the accelerator with your right foot, feeling the car's forward momentum; 3. Press the handbrake button and push it downward to release the handbrake; 4. The car climbs upward, completing the hill start. The correct starting procedure is: when the car body shakes after releasing the clutch with your left foot, slowly release the brake with your right foot. Avoid releasing the brake too quickly, and keep the clutch steady. If the car shows signs of rolling backward after completing these steps, quickly press the brake and clutch to stop the car, then start again. Stalling usually occurs when the clutch is not held steadily at the semi-engaged point, requiring repeated practice to improve clutch control.

What are the effects of not changing brake fluid?

Not changing the brake fluid will reduce braking force, causing air resistance in the brake lines, thereby affecting braking performance. It may also corrode the brake lines, leading to damage to the internal valves of the anti-lock braking hydraulic assembly, severely impacting the transmission response of the brake system. Prolonged use of brake fluid can also cause wear to the rubber cups and pistons in the brake pump, resulting in contaminated brake fluid. Brake fluid is a solution that easily mixes with water. Over time, some moisture or impurities may enter through the holes in the fluid reservoir, and mixing with water can significantly lower the boiling point of the brake fluid. Once it reaches a certain level, when the driver uses the braking system, many air resistances due to high-temperature evaporation may appear in the pipelines. At this point, the braking force will noticeably decrease or even fail, increasing the risk of driving.
