Brake fluid needs to be replaced because: After being used for a period of time, brake fluid will deteriorate, affecting the braking system. Additionally, the volume of brake fluid changes with temperature variations. The brake fluid reservoir is equipped with a vent hole, through which absorbed air may contain moisture or impurities, leading to reduced braking force or brake failure. Brake fluid plays a transmission role in the vehicle's braking system. When you press the brake pedal with your foot, with the assistance of the vacuum booster, it pushes the master cylinder, which in turn pushes the brake fluid. The force from your foot is transmitted through the brake fluid to the brake calipers at each of the four wheels. The brake calipers then push the brake pads, which squeeze the brake discs to generate braking force.

How to Use the Delayed Headlight Shut-off Feature on MG6?

To deactivate the delayed headlight shut-off feature on the MG6, simply flick the light stalk twice in the same manner as turning it on. Below are the detailed steps to disable the MG6's delayed headlight shut-off: 1. To set up the delayed headlight shut-off function, first turn off the headlights, then remove the key after turning off the engine. Immediately flick the light stalk twice as if turning it on to activate the delayed shut-off feature. To set the duration before the headlights automatically turn off, you can find this option in the dashboard settings and adjust the time according to your personal preference and needs. 2. The delayed headlight shut-off, also known as the 'Follow Me Home' feature, essentially keeps the headlights on for a period after the vehicle is turned off, providing external lighting for the owner after exiting the car. This design originally stemmed from many people in Europe and America living in detached houses with private garages, where the vehicle could still offer brief lighting service after parking and closing the garage door. However, some car owners in China do not prefer this feature, in which case they can choose to disable the delayed headlight shut-off.

How Many Months Should You Not Exceed When Buying Tires?

Do not buy tires that are more than 6 months old. Below is relevant information about car tires: 1. Main material of tires: The main material of tires is rubber. A characteristic of rubber is that it ages over time or after prolonged storage, leading to significant changes in the tire's physical properties such as hardness and wear resistance. If aged tires continue to be used, it may lightly affect vehicle performance or, in severe cases, lead to tire blowouts. 2. Tire lifespan: Generally, all-season or economy tires have a lifespan of 3-5 years, with a mileage of about 50,000 kilometers. Under normal circumstances, tires have a sufficient lifespan of 1 year from the date of manufacture. However, for high-performance tires, the lifespan is only 20,000-30,000 kilometers. If the price is reduced, purchasing them may also be considered.

What Are the Common Malfunctions of ETC Cards?

ETC card device failure may result in no response, displaying that the card is not properly inserted, or ETC card deduction failure. Below are solutions for ETC malfunction indicators: 1. Reduce speed and maintain distance when passing through ETC lanes: When vehicles pass through ETC lanes, their speed must not exceed the limit indicated by on-site speed signs, and a safe distance should be maintained from the vehicle ahead. 2. Manual lanes can be used if ETC lanes malfunction: If encountering a malfunction or congestion in an ETC lane, drivers can choose to pass through a manual lane without losing any discount benefits. 3. Pass only when the onboard electronic tag displays normal status: Before entering an ETC lane with a vehicle equipped with an onboard electronic tag (OBU), drivers should insert the ETC co-branded card into the electronic tag. The vehicle can proceed through the ETC lane only after the electronic tag shows normal operation. 4. Some vehicles may require cutting the metal explosion-proof film on the windshield: Due to the metal explosion-proof film on the windshields of certain vehicle models, microwave signals may be blocked, preventing OBU installation and activation or successful passage through ETC lanes after installation. It is recommended to seek a professional auto beauty shop to cut the corresponding area on the explosion-proof film.

What Are the Advantages of LED Taillights?

LED taillights possess a series of technical advantages. Below is a detailed introduction about LED taillights: 1. Automobile taillights, including the lamps and bulbs in the rear of the vehicle. Among them, the function of the lamps is to aggregate and then emit the light from the bulbs, thereby enhancing the brightness and range of the light emitted by the bulbs, as well as changing the color of the bulb's light through the color of the lamps. Currently, there are mainly three types of bulbs: halogen automotive bulbs, HID automotive bulbs, and the emerging LED automotive bulbs. 2. LED taillights are an innovative type of brake lights and taillights that use long-lasting LED light sources. The bulbs are made of diodes, which are brighter than ordinary bulbs and have a faster response speed. LED (Light-Emitting Diode, meaning light-emitting diode in Chinese) is a semiconductor that can convert electrical energy into visible light. It changes the principle of incandescent tungsten filament lighting and energy-saving lamp three-primary-color powder lighting, instead using electric field lighting. They can signal other vehicles and pedestrians when the car brakes, turns around, or changes direction. LED taillights have excellent light source intensity, maintaining extremely high visibility even in foggy conditions.

Is a 2.3-meter parking space compliant with standards?

2.3-meter parking spaces do not meet the standard. Generally, 2.5x5.3m is considered the optimal standard parking space size, with the minimum width for parking spaces (excluding compact spaces) being 2.4 meters. Parking spaces are categorized into two types based on size: Large parking spaces: 15.6 meters in length and 3.25 meters in width, suitable for medium and large vehicles. Small parking spaces: 6 meters in length and 2.5 meters in width, suitable for small vehicles. Parking spaces are also classified into three types based on arrangement: Parallel parking spaces: Standard length of 6 meters and width of 2.5 meters. Angled parking spaces (30°, 45°, 60° angles): Diagonal length of 6 meters, width of 2.8 meters, with a perpendicular distance between the two diagonal lines maintained at the standard 2.5 meters. Perpendicular parking spaces: Length greater than or equal to 5 meters (typically set at 6 meters), width of 2.5 meters. Generally, 2.5x5.3m is considered the optimal standard parking space size.

What are the dimensions (length, width, height) of the Ford Focus Hatchback?

The body dimensions of the Ford Focus Hatchback are 4378mm in length, 1810mm in width, and 1468mm in height, which are the official data. The length of the Ford Focus Hatchback refers to the distance between two vertical planes perpendicular to the vehicle's longitudinal symmetrical plane and touching the outermost protruding points at the front and rear of the vehicle. The width refers to the distance between two planes parallel to the vehicle's longitudinal symmetrical plane and touching the outermost rigid fixed protruding points on both sides of the vehicle. The height refers to the distance between the highest point of the vehicle and the supporting plane. The Ford Focus Hatchback is equipped with a 1.5T engine paired with an 8-speed automatic transmission, delivering a maximum horsepower of 174Ps and a maximum torque of 234 Nm. There are national regulations regarding vehicle dimensions. According to the national standard "GB1589-89," the total width of a vehicle does not include side mirrors. The limitation on vehicle width is to provide sufficient lateral clearance for overtaking between adjacent lanes. This means that, under national standards, the significance of vehicle width data is to ensure enough space during overtaking, preventing accidents due to excessive width or situations where road markings are narrower than the vehicle's width. Additionally, national regulations stipulate that the total width of a vehicle must not exceed 2.5m to meet the requirements of public road usage.
