Should front fog lights or rear fog lights be turned on when driving in foggy conditions?

When driving in foggy conditions, both front fog lights and rear fog lights should be turned on. The front fog lights serve to provide the driver with better visibility, while the rear fog lights help vehicles behind to see more clearly. Generally, fog lights are used in conjunction with hazard warning lights. Additional information: Below is an introduction to car lights: 1. Front fog lights: The color is green. On the left are three diagonal lines crossed by a curved line, and on the right is a semi-elliptical shape. Front fog lights are used to improve illumination in unclear road conditions ahead, providing a high-intensity scattered light source that penetrates thick fog, serving to alert oncoming drivers. 2. Rear fog lights: The color is yellow. On the left is a semi-elliptical shape, and on the right are three diagonal lines crossed by a curved line. The purpose of rear fog lights is to make the vehicle more visible to other road users behind in low-visibility conditions such as fog, snow, or rain. They are installed at the rear of the vehicle and have a higher luminous intensity than tail lights.

Is the Front Windshield Film Applied on the Inside or Outside?

The front windshield film is applied on the inside. Applying it on the outside would expose it to wind and sun, significantly reducing its lifespan. Applying it on the inside provides better protection and, in case of an accident, helps hold shattered glass together, preventing injuries to passengers from flying glass. If applied on the outside, broken windshield glass could pose a risk to the driver and passengers, failing to serve its anti-shatter purpose. Car window film is a thin layer applied to the front and rear windshields, side windows, and sunroof. This film, also known as solar film or anti-shatter heat insulation film, primarily blocks UV rays, reduces heat, and prevents injuries from sudden glass breakage. Additionally, its one-way visibility feature helps protect personal privacy.

Where is the oil dipstick on the BMW X1?

The BMW X1 uses an electronic system to record oil levels, which differs from the traditional dipstick used in other vehicle models. This vehicle employs an electronic system to inform the driver about the engine oil condition and quantity. Owners can follow the maintenance schedule prompted by the system or as recommended by dealers for regular service at 4S shops. The BMW X1 is a compact SUV model, available in both four-wheel drive and rear-wheel drive configurations. It offers four variants: xDrive18i, xDrive18d, xDrive20d, and the top-tier X1 xDrive28i. The dimensions of the BMW X1 are 4454mm in length, 1798mm in width, and 1545mm in height, with a wheelbase of 2760mm.

What to Do If the Car Is Not Driven for a Long Time?

If a car is not driven for a long time, the following precautions should be taken when parking: 1. Give the car body a thorough cleaning before long-term parking: This helps prevent corrosion and oxidation of the car body. Use a car cover to protect the vehicle from dust and other damage. 2. Disconnect the negative terminal of the battery (power off): This prevents power consumption. When restarting, simply reconnect the terminal. This ensures the car won't fail to start due to a drained battery from prolonged inactivity. 3. Check the tire pressure: For long-term parking, such as over six months, check the tire pressure and inflate the tires if the pressure is insufficient. 4. Do not leave food or drinks in the car: Avoid placing food or beverages inside the car during long-term parking. Opened food and drinks can mold within three to four days, causing air pollution inside the car.

Who is responsible if the front car suddenly brakes and causes a rear-end collision?

The responsibility lies with the rear car. Below are explanations of several common rear-end collision scenarios: 1. Rear-end collision caused by the front car reversing or rolling back: These situations often occur, typically at intersections while waiting for traffic signals. If the front car fails to engage the foot brake or mistakenly shifts into reverse, or if the vehicle rolls back while starting on a slope, the front car bears full responsibility. As long as the rear car did not move before the collision, this can be proven. 2. Emergency braking by the front car: If the rear car maintains a safe distance, a collision would not occur. However, a complete determination requires reviewing the rear car's dashcam footage. If the front car intentionally brakes suddenly, it may also share some responsibility. 3. Rear-end collision caused by the front car changing lanes or cutting in: Overtaking or lane changes must not affect normally moving vehicles. In such cases, regardless of whether lane changes are permitted on that road section, the lane-changing vehicle bears full responsibility, and the normally moving vehicle is not at fault. 4. Rear-end collision caused by the front car parking illegally: Illegal parking here refers to stopping arbitrarily on a normally flowing road, which may cause the rear car to misjudge the front car's movement and lead to a collision. In this situation, the front car is already in violation, so it bears full responsibility, and the rear car is not at fault.

What needs to be replaced for a 15,000-kilometer maintenance?

A 15,000-kilometer maintenance requires replacing the engine oil, oil filter, air filter, and cabin air filter. Engine oil is the lifeblood of the engine and is crucial for its operation. Inside the engine, oil not only lubricates but also cleans, seals, cushions, prevents rust, and dissipates heat. Without engine oil, the engine cannot function properly. Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain components of the vehicle, also known as vehicle servicing. Modern car maintenance primarily includes the engine system (engine), transmission system, air conditioning system, cooling system, fuel system, power steering system, and other related areas. The purpose of car maintenance is to keep the vehicle clean, ensure normal technical conditions, eliminate potential hazards, prevent faults, slow down deterioration, and extend the service life.
