To open the BMW 3 Series trunk with foot sensing, you can swipe your foot near the rear bumper sensor camera, next to the exhaust pipe, to activate the opening mechanism. The BMW 3 Series models include: BMW 320i, BMW 325im, BMW 320lim, BMW 325lixdrivem, and BMW 320li. Taking the 2021 BMW 320i as an example, it is a mid-size car with body dimensions of: length 4719mm, width 1827mm, and height 1459mm. The 2021 BMW 320i is equipped with a 2.0t turbocharged engine, delivering a maximum horsepower of 156ps, a maximum torque of 250nm, and a maximum power of 115kw, paired with an 8-speed automatic transmission.

Having driven a BMW 3 Series for several years, I can say the foot-activated trunk opening feature is an absolute lifesaver. When standing at the rear with both hands full, just gently sweep your foot under the bumper - the trunk opens automatically. The sensor is usually located slightly below center on the rear bumper. The motion should be smooth, like a soccer kick, not forceful. Keep your key fob on you as it typically needs to be within 1-2 meters for detection. My car's Comfort Access system works reliably even in rain, though keeping the sensor area clean helps prevent accidental activations. Some newer 3 Series models even add control options in the mobile app - the whole design is thoughtful and convenient.

As a tech enthusiast, I'm particularly fascinated by the kick-to-open trunk feature on the BMW 3 Series. It relies on key fob detection and underbody sensors to activate electric opening upon detecting leg motion. To operate, stand near the rear of the vehicle and make a slight kicking motion in the area beneath the bumper - the system will unlock upon recognition. The technology involves trendy hands-free design principles similar to those used in premium vehicles. Just keep the key in your pocket; if unresponsive, check for dead batteries or sensor obstructions. This innovation allows owners quick access in crowded parking lots, demonstrating superb user-friendliness.

As a homemaker who shuttles kids and shops daily, this foot-activated sensor is a lifesaver. When my arms are full and I approach the rear, just a gentle foot motion opens the trunk—no fumbling for switches. Located centrally beneath the rear bumper, a simple sweep does the trick (keep keys nearby). It saves me precious time and feels safer when the trunk's slippery after rain. The operation is intuitive and dependable—highly recommend new owners try this convenience booster.

Can the Volkswagen Daytime Running Lights Be Turned Off?

Volkswagen daytime running lights cannot be turned off. Daytime running lights do not have an off switch and serve as a signal rather than providing illumination. They make the vehicle more easily identifiable during daytime driving. When the car engine starts, the daytime running lights automatically turn on and gradually increase in brightness to attract the attention of other motor vehicles, non-motor vehicles, and pedestrians on the road. Definition of Daytime Running Lights: There are generally two, with the outer one being the light switch. Daytime running lights are designed to signal the presence of the vehicle to the front during the day and are installed on both sides of the front end. When the car engine starts, the daytime running lights automatically turn on and gradually increase in brightness to attract the attention of other motor vehicles, non-motor vehicles, and pedestrians on the road. Night Mode: When night falls and the driver manually turns on the low beam headlights, the daytime running lights automatically turn off.

What is the difference between the large emblem and small emblem of Mercedes-Benz?

Mercedes-Benz large emblem and small emblem mainly represent the difference between standard version and sports version. More details are as follows: Large Emblem: The large emblem of Mercedes-Benz is used in sports version models and sporty exterior modifications. Models with the large emblem are referred to as sports edition vehicles. Additionally, Mercedes-Benz SUV series models and AMG performance series models also adopt the large emblem. Later-released more sporty exterior designs also feature the large emblem. Meanwhile, standard version models and more business-oriented S-Class series models still use the small emblem. Small Emblem: The original Mercedes-Benz emblem consisted of "Benz" surrounded by wheat ears. In 1926, Daimler and Benz merged, and the star emblem was finally combined with the Benz wheat ears, with "Mercedes-Benz" written below the emblem. Later, the wheat ears were replaced with a circle, and the "Mercedes-Benz" wording was removed. With the merger of these two oldest car manufacturers, the company reapplied for a patent for the trademark, and the star emblem within the circle evolved into today's design, which has been used ever since and became one of the world's top ten famous trademarks. This is the small emblem.

Can you get on the highway without ETC?

It is possible to get on the highway without ETC. According to the regulations of the State Council, starting from 2020, vehicles without ETC will not enjoy toll discounts. In the future, only one manual lane will be retained at highway toll stations, and tolls can only be paid through the manual channel. Additionally, newly installed ETC devices cannot be used immediately on the highway; they need to be activated first. During free holiday periods, vehicles can still use the highway. For vehicles already equipped with ETC, passing through ETC lanes will not incur charges. ETC charging principle: There will be one or more ETC lanes on the highway. Through dedicated short-range microwave communication between the vehicle's electronic tag installed on the windshield and the microwave antenna in the ETC lane at the toll station, the computer network technology is used to settle accounts with the bank in the background. This achieves the purpose of vehicles not needing to stop at toll stations to pay road and bridge fees, all based on the principle of passing first and deducting fees later. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and environmentally friendly: Green and low-carbon, vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution; Reduced wear and tear: Saves costs, reduces the frequency of vehicle starts and brakes, lowers wear and fuel consumption, and users can also enjoy a 5% discount on tolls; Improved efficiency: The theoretical efficiency of ETC lanes can be increased by 2-3 times, making traditional ETC more updated, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council clearly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation cards in key city clusters will be basically achieved, and the proportion of vehicles equipped with ETC will be significantly increased." It also explicitly set the goal in the "13th Five-Year" comprehensive transportation development indicators that "by 2020, the ETC usage rate for road passenger vehicles will reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and the ETC usage rate for passenger vehicles, efforts will be made in the future to promote the use of ETC for trucks and explore the deep integration of the ETC system with vehicle-to-vehicle communication, vehicle-road coordination, and other smart transportation development directions, providing comprehensive travel services for vehicle owners. This means more application scenarios will support ETC applications.

How many points will be deducted for making an illegal U-turn over a solid line?

Making a U-turn over a solid line is a traffic violation. According to Article 26 of the Road Traffic Safety Law, violators will be fined 200 yuan and receive a 3-point penalty. Generally, on long roads, white solid lines are usually present in the middle section or before intersections. If the line is a yellow dashed line or white dashed line, a U-turn is allowed. However, U-turns are strictly prohibited over any solid line. Scenarios where U-turns are permitted: If there is a clear U-turn sign at the intersection, a U-turn can be made. If there is a U-turn traffic light, the U-turn must follow the signal's instructions. If there is no traffic light, a U-turn can be made based on the specific situation, provided it does not obstruct other vehicles or pedestrians. Intersections without explicit prohibitions against U-turns or left turns allow U-turns: If a location is not explicitly marked as prohibiting U-turns, then U-turns are allowed. 'No explicit prohibition against U-turns' means that as long as there are no 'No U-turn' signs, 'No Left Turn' signs, or solid lines in the middle of the road, a U-turn can be safely made. U-turns are also allowed over yellow grid lines: Yellow grid lines are no-parking zones typically painted at intersections prone to congestion due to temporary parking, important facility entrances, or other necessary locations. Any vehicle stopping on these grid lines (including waiting for traffic lights) is committing a violation. Although parking is not allowed in yellow grid zones, U-turns are permitted as long as there are no central road barriers. Yellow grid lines without central barriers are equivalent to 'U-turn permitted.' Intersections with U-turn traffic lights: This is straightforward—if there is a U-turn traffic light, follow the signal; a U-turn is only allowed on green. When 'No Left Turn' and 'U-turn Permitted' signs appear together: U-turns are allowed, but left turns are prohibited. However, 'No U-turn' does not mean the same as 'No Left Turn.' Precautions when making U-turns at intersections: Observe the road markings. If they are solid lines, U-turns are prohibited under any circumstances. Continue driving to find a suitable location for a U-turn. If there is a 'No Left Turn' sign ahead, even if there is no mention of prohibiting U-turns, making a U-turn at that intersection is not allowed because the actions for left turns and U-turns are very similar, and a U-turn always involves a left turn first. U-turns must be made from the innermost left-turn lane. If you are in the second left-turn lane, a U-turn at that intersection is also not allowed. When making a U-turn, always yield to vehicles going straight. Only proceed with the U-turn if it does not interfere with straight-moving traffic; otherwise, you will bear full responsibility for any accidents. Near the intersection stop line, lanes usually have guiding arrows for vehicles to choose their direction. The leftmost lane does not always have a left-turn arrow. On some roads, if there is a straight arrow, even without explicit 'No U-turn' signs, U-turns are not permitted. Making a U-turn on a pedestrian crosswalk is also a traffic violation.

Is a signature required for vehicle damage assessment?

Damage assessment reports are issued by insurance companies and do not require signatures from both vehicle owners. Below are the procedures to follow after a traffic accident occurs: Stop and call the police: In case of a serious collision between two vehicles, immediately stop the car, turn on the hazard lights, place a triangular warning sign 150 meters behind the vehicle, and then call the traffic police. Protect the scene: For major traffic accidents, it is necessary to protect the accident scene until the traffic police arrive for investigation. Accident claims: If there are casualties, keep all hospital documents. You can go to the 4S shop or damage assessment center designated by the insurance company for assessment. Based on the insurance company's investigation and the determination of the liability statement, the insurance company will provide certain compensation.

Who is responsible for organizing and implementing the secondary maintenance of vehicles?

Vehicle secondary maintenance is organized and implemented by maintenance enterprises. The following is a detailed introduction to vehicle secondary maintenance: Engine: Secondary maintenance of a vehicle requires checking whether the engine's idle, medium, and high-speed operating conditions meet standards, as well as whether the cylinder pressure and vacuum degree are up to par. Clutch: This item involves checking the convenience, smoothness, and reliability of clutch operation to ensure that the clutch is easy to use, free of abnormalities, and that the hydraulic system does not leak oil. Tires: Check whether the tire pressure is normal, whether there are debris such as small stones in the tire tread that could damage the tires, and whether there are signs of aging or bulging in the tires.
