What Causes Hard Braking?

What are the four situations where overtaking is not allowed?

The "Road Traffic Safety Law" clearly stipulates four situations where overtaking is not allowed: 1. When turning: The vehicle in front is turning left, making a U-turn, or in the process of overtaking; 2. When facing oncoming traffic: There is a possibility of overtaking vehicles coming from the opposite direction; 3. During emergency situations: Overtaking is allowed for vehicles performing emergency tasks, such as police cars, fire trucks, ambulances, or engineering rescue vehicles, when rushing to the scene, disaster relief, saving lives, or escorting important security items; 4. When road conditions are poor: Overtaking is not allowed on complex road sections, such as intersections, pedestrian crossings, railway crossings, narrow bridges, or steep descents, or during windy, rainy, snowy, or foggy weather when visibility is less than 30 meters.

How Far Can the Car Key Be from the Vehicle Before It Won't Open the Door?

The maximum reception distance for a car key remote is approximately 50 meters. This distance is achievable only under conditions without any electronic interference or physical obstructions. Typically, the signal remains strong and is most easily received within a range of about 10 meters. Additionally, the reception distance can vary depending on the quality of the remote key and other factors. A remote key allows users to lock and unlock the car doors from a distance without inserting the key into the lock. Its advantages include the ability to operate the lock conveniently from afar, regardless of whether it's day or night, and without needing to locate the keyhole. The remote key emits a weak radio signal, which is received by the car's antenna. The electronic control unit (ECU) then identifies the signal code, and the system's actuator performs the locking or unlocking action. This system primarily consists of two components: a transmitter and a receiver.

How Often Should Semi-Synthetic Engine Oil Be Changed?

Semi-synthetic engine oil is generally replaced every 7,500 kilometers. Below is extended knowledge about engine oil: 1. Classification: Mineral oil, semi-synthetic engine oil, and full synthetic engine oil. The classification is mainly based on the differences in base oils. Typically, mineral oil uses Group II and III base oils, semi-synthetic engine oil uses Group III and IV base oils, and full synthetic engine oil uses Group IV and V base oils. 2. Lubrication performance: Mineral oil has the poorest performance, full synthetic engine oil has the best performance, and semi-synthetic engine oil falls between the two. 3. Oil change intervals: Mineral oil is usually changed every 5,000 kilometers, semi-synthetic engine oil every 7,500 kilometers, and full synthetic engine oil every 10,000 kilometers. If a vehicle is left unused for more than three months, it is recommended to change the engine oil before using it again.

What causes the acceleration vibration in the 2017 Cadillac ATS-L?

The acceleration vibration in the 2017 Cadillac ATS-L can be caused by the following reasons: 1. Excessive carbon deposits: Incomplete absorption of gasoline into the engine leads to excessive carbon buildup, resulting in incomplete combustion. 2. Clogged filters: Failure to replace the oil filter, air filter, or cabin air filter for an extended period causes clogging by impurities, leading to incorrect information transmission by the engine control unit. 3. Severe gear wear: Prolonged use without replacement of the timing gear causes significant wear, resulting in loose meshing, abnormal noise, and jerking; uneven tire tread with bulges or foreign objects. 4. Damaged spark plugs: Worn spark plug electrode gaps affect insufficient spark, causing incomplete combustion of the air-fuel mixture and impacting acceleration.

Is the Engine Maintenance Kit Useful?

Engine maintenance kits are useful. Here are the specific details about engine maintenance kits: 1. Engine cleaning and maintenance: The primary function is to clean the sludge inside the engine and add an oil protector to extend the service life of engine components. 2. Fuel intake system cleaning: The main purpose is to clean the carbon deposits in the fuel intake system. 3. Catalytic converter cleaning: This process cleans the carbon deposits on the surface of the catalytic converter and enhances its reduction capability. It is recommended to perform this cleaning every 30,000 to 60,000 kilometers to extend the service life of the catalytic converter, which helps with fuel consumption and engine exhaust emissions.

Why is the left side too narrow when reversing into the left parking space?

Right reversing into the parking space, the left side is very wide, and the right side is very narrow for the following reasons: Unstable vehicle speed: The speed is too fast or sometimes fast and sometimes slow. The speed should be slow, and the speed of turning the steering wheel and stepping on the clutch should also be the same, not one fast and the other slow. Also, your own feeling of the car body is important. After reversing into the parking space, hold the steering wheel steadily and make some adjustments yourself. Practice a few more times. Misjudgment: Misjudgment of the 30 cm distance when reversing into the parking space. Turning the steering wheel too fast: The vehicle speed suddenly increases when turning the steering wheel. When the steering wheel is turned to the limit, part of the power provided by the engine will be absorbed by the power steering pump, resulting in a decrease in the power provided to the tires by the engine. At this time, you should release the clutch a little to maintain the original speed.
