Methods to open the trunk of a BMW M4 when there's no power: Remove the triangular cover on the left front door of the BMW M4, where you'll find a keyhole. Use mechanical unlocking to open the trunk. When there is power, you can press the trunk switch on the remote key. Hold this switch down, and the trunk lid will automatically pop open. Here are some items that should not be placed in the trunk: 1. Flammable and explosive items. As temperatures rise, these can become hazardous. If caught by traffic police, fines can go up to 100,000 yuan. 2. Fruits. Fruits can easily rot. The car interior is an enclosed space that can get hot, causing fruits to spoil and release unpleasant odors.

After all these years of repairing cars, a dead battery in the BMW M4's trunk is really not a big issue. The car key usually comes with a small metal emergency key. You'll need to locate the area near the trunk button where there might be a small plastic cover. Gently pry it open, insert the key and turn it - usually counterclockwise - to manually unlock it. If that doesn't work, BMW trunks have an emergency release mechanism inside. You'll need to access it by climbing through the rear seats to find a small pull tab hidden on the inner side of the trunk lid. Just pull it to open. Be careful when climbing to avoid scratching the interior or hurting yourself. Safety first - if the battery is completely dead, check why afterwards. It might just be an aging battery that needs replacement at a shop. BMWs are well-designed cars - regular maintenance goes a long way in preventing such hassles.

What are the methods for car tire repair?

Car tire repair methods can include patch repair, mushroom plug repair, and hot vulcanization repair. Below are detailed introductions to these repair methods: 1. Patch repair: This method involves removing the tire from the rim, locating the puncture, cleaning the surrounding area of debris, and then applying a specialized repair patch to the inside of the tire to seal the leak. The advantages of patch repair are its affordability and relatively durable repair effect, without damaging the tire tread. However, the downside is that it cannot address damage on the outer side of the tire. After prolonged high-speed driving or water exposure, the repaired area may start leaking again. 2. Mushroom plug repair: The principle is quite similar to patch repair, with the key difference being that a mushroom-shaped plug is used instead of a patch in the final step, hence the name. The advantage of this method is that it can repair both inner and outer tire damage, addressing the limitations of patch repair. It seals the puncture site, ensuring the tire's airtightness, and blocks the puncture channel, providing dual protection for the tire damage. 3. Hot vulcanization repair: This method builds on the patch repair by using a vulcanizing machine for high-temperature vulcanization treatment. The advantage of hot vulcanization repair is its superior airtightness and stronger bond between the patch and the tire. However, this method requires a higher level of technical skill. If not performed expertly, it can easily damage the tire. Therefore, this method is not suitable for passenger car tires but is more appropriate for thicker truck tires.

What does it mean when the Mercedes-Benz Run-Flat Indicator stops working?

When the Mercedes-Benz Run-Flat Indicator stops working, it indicates that the pressure in at least one tire deviates from the pressure recorded during the last reset. It is necessary to check the tire pressure and perform a reset. If the tire pressure is insufficient, the dashboard will reactivate the Run-Flat Indicator. The vehicle owner should first check the pressure in all four tires. If the indicator persists after adjustments, the tire pressure needs to be restored and reset. If one or more tires have low pressure, first identify which tire(s) are affected. The recommended pressure is 2.4 bar for the front tires and 2.6 bar for the rear tires. After addressing any leaks, turn the ignition to position 2. Use the buttons on the steering wheel to access the maintenance menu on the dashboard, select 'Tire Pressure Normal,' and confirm to stop the warning. Reset method: Turn the key to position 2, use the left menu button on the steering wheel to display the odometer interface on the dashboard, then press the up button on the left side of the steering wheel; The dashboard will display 'Run-Flat Indicator Reactivated,' press the R button on the dashboard; The dashboard will show whether the tire pressure is normal; Press the plus button on the right side of the steering wheel, wait for 10 seconds, then turn off the key and restart the vehicle.

Do I need to turn on Bluetooth for ETC?

When using ETC on highways, there is no need to turn on the car's Bluetooth or mobile phone Bluetooth. The ETC junction box installed in our car has a short-distance communication response system inside, which will automatically communicate with the sensors on the road, and our car and mobile phone do not need to turn on Bluetooth. There should be about 20 domestic manufacturers. When using ETC, Bluetooth does not need to be turned on. The ETC Bluetooth switch is only used when the ETC device is activated or when the ETC is charging. It will automatically sense when passing through a highway ETC toll station, and Bluetooth does not need to be turned on all the time. ETC is the abbreviation of Electronic-Toll-Collection, meaning electronic toll collection system. To apply, you need to provide the original and photocopy of the vehicle owner's valid ID card and driving license. If it is not the owner who is applying, the agent's valid ID card is also required. The photocopy of the driving license needs to include the page with the most recent annual inspection seal; a bank card for deducting highway tolls; the applicant must be between 18 and 60 years old; and the vehicle must be under the applicant's name. How ETC works: Through the vehicle-mounted electronic tag installed on the windshield, it communicates with the microwave antenna in the ETC lane at the toll station, and uses computer networking technology to settle with the bank in the background, allowing the vehicle to pay the highway or bridge toll without stopping when passing through the toll station. Benefits of installing ETC: Saves time: Eliminates the hassle of waiting in line; Green and environmentally friendly: Green and low-carbon, vehicles pass through the toll station without stopping, reducing noise and exhaust emissions and pollution; Saves wear and tear: Saves costs, reduces the frequency of vehicle starting and braking, reduces wear and fuel consumption, and users can enjoy toll discounts; Improves efficiency: The ETC lane passage efficiency can theoretically be increased by 2-3 times or more, making traditional ETC newer, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.
