What is the method for replacing the key battery of Changan CS75?

What are the reasons for brakes making abnormal noises, failing, and then returning to normal?

The reasons for brakes making abnormal noises, failing, and then returning to normal are: 1. Lack of necessary maintenance on the brake system, excessive impurities in the brake master cylinder, poor sealing, failure of the vacuum booster pump, or dirty brake fluid; 2. Mechanical failure due to improper operation; 3. Severe overloading of the vehicle, which increases the vehicle's inertia under the effect of gravitational acceleration, directly leading to brake failure. The causes of brake failure include: 1. Impurities in the brake master cylinder and poor sealing; 2. Failure of the vacuum booster pump; 3. Dirty brake fluid; 4. Leakage in the brake master cylinder or wheel cylinder; 5. Leakage in the air reservoir or pipeline connections; 6. Severe overloading; 7. Carbonization of the brake drum; 8. Insufficient brake fluid in the brake master cylinder; 9. Wear of the brake master cylinder piston.

What is the replacement interval for BMW B48 spark plugs?

For BMW models equipped with the B48 engine, it is recommended to replace the spark plugs every 30,000 kilometers. If spark plugs are not replaced for a long time, it can lead to various issues such as electrical leakage in the ignition system, increased fuel consumption, reduced power, and most importantly, difficulty in starting the engine, which affects the normal use of the vehicle. Spark plug replacement interval: Under normal maintenance conditions, spark plugs should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is advisable to follow the owner's manual. The following standards can be used as a reference for maintenance and replacement: platinum spark plugs should be replaced at 40,000 kilometers, standard nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Steps for replacing spark plugs: Open the hood and lift the plastic cover of the engine. Remove the high-voltage ignition wires, marking each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris like leaves or dust and ensure they are thoroughly cleaned. Place the new spark plugs into the spark plug holes, hand-tighten them a few turns, and then use the socket to tighten them further. Reinstall the high-voltage ignition wires in the correct firing order and secure the cover back in place.

What does 'back' mean on a car?

In the context of a car, 'back' refers to making a U-turn. A U-turn is an operation that changes the direction of the car by 180 degrees under road conditions where it is permitted. Sometimes, a U-turn is also required in non-road conditions such as parking lots, and the method is basically the same. Making a U-turn must strictly comply with the regulations of road traffic management. Motor vehicles are not allowed to make U-turns at railway crossings, crosswalks, curves, narrow roads, bridges, steep slopes, ramps, or sections of the road where it is prone to danger. The precautions for making a U-turn are: 1. Choose a safe section of the road where U-turns are allowed, with less traffic, and do not hinder the normal passage of vehicles and pedestrians; 2. Choose to make a U-turn at a dashed line, not at a solid line; 3. When making a U-turn at an allowed section of the road or intersection, turn on the left turn signal in advance.

What is the tire pressure for Tesla?

Tesla's tire pressure range depends on the type of tires installed. The recommended tire pressures for different tires are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: should not exceed 3.5 bar. Hazards of overinflated tires: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates uneven wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Excessive stretching of tire cords reduces elasticity, increasing the load on the vehicle during driving; Decreases puncture resistance. Sharp objects like nails or glass can easily penetrate the tire, leading to internal cracks or blowouts. Hazards of underinflated tires: Increases friction with the road surface, raising fuel consumption; Causes heavy steering and deviation, compromising driving safety; Increases movement of tire components, leading to abnormal heat due to excessive rolling; Reduces the functionality of cords and rubber, causing delamination or cord breakage, and excessive friction with the rim, damaging the bead area and causing abnormal wear; Multiplies friction with the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing strength. High-speed driving may result in blowouts; Increases tire deformation, leading to sidewall cracks and excessive flexing, causing overheating, rubber aging, cord fatigue, and breakage, while also enlarging the contact area and accelerating shoulder wear.
