Airbag deployment requires a relative speed greater than 50km/h and a reverse-direction acceleration of over 40g at the moment of collision. Below are specific details about airbags: 1. Airbag deployment: The controller relies on three acceleration sensors (not speed sensors) to send the deployment command to the airbag. Therefore, even at high speeds, if the acceleration value (impact force) during collision does not exceed the set threshold, the airbag will not deploy. 2. Function of airbags: The electronic-control safety airbag system is a passive safety (see vehicle safety performance) protection system. When used in conjunction with seat belts, it provides effective collision protection for occupants. During a vehicle collision, airbags can reduce head injury rates by 25% and facial injury rates by approximately 80%.

Why is the Volkswagen Tacqua so cheap?

Tacqua, as a new compact SUV under the Volkswagen brand, is priced between 114,900 and 159,900 yuan, with the entry-level model starting at just over 100,000 yuan. It is relatively inexpensive due to high modularization saving significant costs, a variety of powertrain options, and average interior materials. The main reasons for Tacqua's affordability are as follows: 1. High modularization saves substantial costs; Tacqua's engine, chassis, and even exterior and interior designs are products of modularization, which is why Volkswagen cars often give a very similar impression. Modular production means various components can use the same molds and standards, saving considerable costs in R&D and design, allowing the vehicle's pricing to be lower than competitors and offering greater discounts. 2. A variety of powertrain options; Tacqua offers three powertrain choices: 1.5L, 1.2T, and 1.4T. From the powertrain configurations across different models, it's clear that the 1.5L version is the main focus. Considering that the engine accounts for a significant portion of a car's cost, savings here can elevate the vehicle's configuration level, which is why Tacqua's entire lineup is well-equipped. 3. Average interior materials; Compact SUVs from joint-venture brands generally use average materials and craftsmanship, naturally aimed at cost savings. Inside the Tacqua, most touchable areas are made of soft-touch plastic materials, which, despite some texture, still feel very plasticky.

What documents are needed to activate ETC?

To activate ETC, the required documents are: the vehicle owner's ID card and vehicle license. If the process is handled by an authorized agent, the agent's ID card must also be presented. ETC activation method: Insert and remove the ETC card twice consecutively until the electronic tag screen displays "Bluetooth is on." If "Tag invalid" appears when inserting and removing the card twice without attaching the electronic tag, this is normal and does not affect activation. Alternatively, you can press the button on top of the electronic tag to enable Bluetooth. Turn on your phone's Bluetooth, open the corresponding mobile app (usually a download QR code is provided on the electronic tag), and enter the device activation interface. Click "Device Connection" and wait patiently for the "Connection Successful" prompt. Once connected, upload a photo of the vehicle's front to complete activation. How ETC works: Through dedicated short-range communication between the vehicle-mounted electronic tag installed on the windshield and the microwave antenna in the ETC lane at toll stations, the system uses computer networking technology to process backend settlements with the bank. This allows vehicles to pass through highway or bridge toll stations without stopping while paying the required fees.

What does a gear with an exclamation mark on the dashboard mean?

A gear with an exclamation mark inside is the automatic transmission fault warning light, indicating that there is a fault in the transmission or the transmission lubricant is below the normal range. It is necessary to replace the transmission oil promptly. The exclamation mark is a common fault warning in cars. In addition to the exclamation mark inside a gear, there are four other forms of exclamation marks: an exclamation mark inside a triangle, an exclamation mark in the middle of a circle with parentheses, an exclamation mark in the middle of a horizontal line below parentheses, and a yellow bulb with an exclamation mark. Below is a detailed analysis of these four situations: General fault: An exclamation mark inside a triangle. If this symbol lights up, it indicates a fault in the general performance or components and functions of the car. Main issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, engine oil pressure sensor failure, etc. It is necessary to go to a 4S shop for inspection to identify the source of the fault. Brake system fault: An exclamation mark in the middle of a circle with parentheses. This represents a warning for the brake system, mainly indicating a brake system malfunction or low brake fluid level. The brake system should be inspected immediately to avoid accidents. Tire pressure abnormality: An exclamation mark in the middle of a horizontal line below parentheses. This represents the tire pressure monitoring warning light, which lights up when the tire pressure of the car is too low. Check the tire pressure and restore it to the normal range. Lighting fault: A yellow bulb with an exclamation mark. This is the lighting fault indicator, indicating a fault in one of the car lights. Solution: Go to a 4S shop for inspection and repair as soon as possible, or you can check it yourself, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to see where the problem lies.

What are the tips for the reverse parking test in Subject 2?

Reverse parking operation tips: After getting into the car, the driver should first adjust the seat and rearview mirrors, fasten the seat belt, then shift the car into reverse gear, release the parking brake lever, and start reversing at idle speed while observing the garage through the right rear window. When the black edge of the right rear window aligns with the right boundary line of the garage, turn the steering wheel steadily to the right to the limit position. After the car enters the garage, the driver should look back at the left rearview mirror. When the entire left boundary line of the garage appears, immediately straighten the steering wheel. When the left door handle is level with the bottom line of the garage as seen in the left rearview mirror, stop the car immediately. Points deduction items for reverse parking are as follows: Not following the prescribed route or sequence: deduct 100 points; vehicle body crossing the line: deduct 100 points; failing to park in the garage: deduct 100 points; stopping midway: deduct 100 points. The full score for Subject 2 is 100 points, with evaluation criteria set for failing, deducting 20 points, deducting 10 points, and deducting 5 points. The test is passed if the following conditions are met: ① For large passenger vehicles, tractors, city buses, medium passenger vehicles, and large trucks, a score of 90 or above is required; ② For other vehicle types, a score of 80 or above is required.

How to Exit the Parking Space Without Scraping the Adjacent Vehicle?

Turning the steering wheel to full lock should be fine. There's a reference point: when you see the wheel, maintain at least 3 meters from it; when you see the bumper, keep 1 meter; and when you see the license plate, it's about... you can try it out~ When you reverse into the parking space, you might often encounter the phenomenon where the left side is too wide while the right side is too narrow. This indicates that you turned the steering wheel to full lock too early at the starting line. The correct timing is to turn the steering wheel to full lock right at the moment when the left rearview mirror aligns with the starting line. This is the first point. The second point is, after reversing into the parking space and noticing the right side is too narrow, you should adjust the steering wheel to the left (adjust towards the wider side), and vice versa. When the rear of the car is centered, immediately straighten the steering wheel. This way, the issue of one side being wider than the other won't occur. Exiting the parking space is similar to making a sharp turn. If there's still space behind before exiting, you can reverse further to position the car as close to the right side of the parking space as possible. Then, shift into drive and move forward. When you feel that half of the car body has passed the parking space line (the driver has already exited the parking space line), you can turn the steering wheel to full lock left and observe the distance between your car body and other vehicles through the left rearview mirror. If this distance is too close, straighten the steering wheel and move forward until the rear wheels pass, then turn the steering wheel to full lock again. If you cannot continue forward due to obstacles ahead, straighten the steering wheel, shift into reverse, and back up. Then, turn the steering wheel to the right to increase the distance and repeat this process to adjust the car's position for a successful exit. Especially in parking lots, if there's a vehicle in front of the parking space exit, here's how to avoid scraping the front car when exiting: when you see the upper edge of the rear bumper of the front car, the distance is approximately 1m. When you see the lower edge of the rear bumper, the distance is about 2m. When you see the lower edge of the rear tire, the distance is roughly 3m.

What is the function of a car condenser?

Car condenser's function is to dissipate heat and cool down the high-temperature and high-pressure refrigerant vapor discharged by the compressor, condensing it into a high-pressure liquid refrigerant. It can cool and liquefy the high-pressure, high-temperature gaseous refrigerant delivered from the compressor. The condenser is a component that continuously compresses the refrigerant from gas to liquid, which is a process of condensation and also a heat dissipation process. More information about car condensers is as follows: 1. The condenser is a component of the refrigeration system, belonging to a type of heat exchanger. It can transform gas into liquid and quickly transfer the heat in the tubes to the air near the tubes. 2. The working principle of the condenser: The refrigerant enters the evaporator, where the pressure decreases, changing from high-pressure gas to low-pressure gas. This process absorbs heat, so the surface temperature of the evaporator is very low. With the help of a fan, cold air can be blown out. The condenser cools the high-pressure, high-temperature refrigerant from the compressor into high-pressure, low-temperature refrigerant. Then, it is vaporized through the capillary tube and sent to the evaporator for evaporation. 3. In car air conditioning systems, the condenser and evaporator are collectively referred to as heat exchangers. The performance of the heat exchanger directly affects the refrigeration performance of the car air conditioning system. They consume a large amount of metal materials, have a large volume, and their mass accounts for 50% to 70% of the total mass of the car air conditioning unit. The space they occupy directly affects the effective volume of the car, making their arrangement very difficult. Therefore, using high-efficiency heat exchangers is extremely important. The condenser and evaporator in the car air conditioning system must match the compressor and also be compatible with the throttle expansion mechanism. The working state of the condenser and evaporator directly affects the capacity (cooling capacity) of the refrigeration system, the power consumption of the compressor, and the overall economy of the air conditioning unit.
