What Lights Should Be Turned on in a Car on Rainy Days?

On rainy days, cars should turn on headlights, position lights, front fog lights, and rear fog lights. Precautions for driving in the rain include: 1. Maintain a safe distance from the vehicle in front; 2. Avoid excessive speed; 3. Remember to use hazard lights to alert vehicles behind during heavy rain; 4. Check waterlogged areas on foot to prevent the car from getting stuck; 5. Do not restart the engine if it stalls. The types and functions of car lights include: 1. Brake lights: Warn people or vehicles behind; 2. Turn signals: Alert vehicles and pedestrians around; 3. License plate lights: Illuminate the car's license plate at night; 4. High beams: Check distant road conditions; 5. Low beams: Clearly see the road ahead; 6. Fog lights: Strong penetration in fog, making it easier for vehicles and pedestrians to notice early; 7. Running lights: Draw attention from other traffic participants; 8. Hazard warning lights: Remind vehicles behind to yield.

What is the difference between Mobil AFE and EP?

Here are the differences between Mobil AFE and EP: 1. Formula: Mobil EP is a long-life engine oil, claimed to last up to 24,000 kilometers or one year before needing a change (likely due to added high-temperature antioxidants); AFE is a fuel-saving formula, meaning it is thinner. AFE has the highest engine noise, while EP offers the best overall performance. 2. Advantages: AFE's advantage is its very low low-temperature pumpability viscosity (MRV), which helps save fuel and allows the oil temperature to rise quickly, making it suitable for winter use; EP has better overall performance, especially in terms of flash point and evaporation loss, meaning superior high-temperature performance. Here is some additional information: 1. Mobil: Mobil is a high-performance lubricant formulated with advanced base oils and balanced additive packages, specifically designed for operation under harsh conditions. 2. Design: Mobil is designed for heavy-duty, low-speed gears that frequently operate under boundary lubrication conditions. These products are formulated with synthetic base oils, offering unique low-temperature fluidity despite their high viscosity grades.

What does Envision 20T mean?

Envision 20T refers to the model equipped with a 1.5L engine. The 20T designation represents the 1.5L powertrain configuration, specifically a 1.5L turbocharged engine. This is a naming convention used by General Motors for their vehicle badging, where 28T denotes a 2.0L displacement model and 40T indicates a 3.0L displacement model. The Envision 20T has dimensions of 4686mm in length, 1839mm in width, and 1686mm in height, with a wheelbase of 2750mm. Its curb weight is 1610kg, and the fuel tank capacity is 66L. The Envision 20T is powered by a 1.5L turbocharged 4-cylinder LFV engine, delivering a maximum horsepower of 169Ps, a maximum power output of 124KW, and a peak torque of 250N·m. It is paired with a 7-speed dry dual-clutch transmission. The Envision 20T features front-wheel drive, with a front suspension using MacPherson strut independent suspension and a rear multi-link independent suspension. It employs a unibody construction.

Is It Okay to Keep the Engine Running with the Air Conditioning On?

It is not recommended to keep the engine running with the air conditioning on for extended periods. The main concern with idling the engine while using the air conditioning is the engine temperature, especially in older vehicles equipped with mechanical fans. Mechanical fans are driven by the engine crankshaft, and at idle, the crankshaft rotates at a slower speed, causing the cooling fan to spin more slowly. Prolonged idling can lead to insufficient engine cooling, resulting in overheating. Below are the hazards of continuously running the air conditioning: 1. Health risks: Continuing to use the air conditioning after the vehicle has stopped can cause the engine to idle, leading to incomplete fuel combustion and the release of exhaust gases containing high levels of carbon monoxide. Since the interior space of the car is small, if the vehicle remains stationary with the air conditioning on and the windows closed, the air inside cannot circulate, leading to poor air quality. Additionally, if carbon monoxide from the exhaust leaks into the cabin, the concentration of toxic gases like carbon monoxide will rise, posing health risks to passengers. 2. Engine damage: Continuing to use the air conditioning after the vehicle has stopped can cause the engine to start with the air conditioning compressor engaged during the next ignition, increasing the load. Over time, this can cause damage to the engine.

Why is there abnormal noise when starting with a CVT transmission?

CVT transmission produces abnormal noise during startup due to suspension system failure. Below is an introduction to related transmission content: 1. 6AT Transmission: Except for shifting from P to D at the start and from D to P when parking, the D gear can be used from beginning to end. The Sport gear can be used when starting, but on flat roads, the speed increase with Sport gear is not as fast as with D gear. The S gear has excellent acceleration performance and is used for overtaking after reaching a certain speed. When the car is running, shifting the D gear to the left switches to M gear mode, allowing control of the gear by pushing the gear lever forward or backward. 2. Classification: Automotive transmissions can be divided into manual transmissions and automatic transmissions, with AT being the commonly referred automatic transmission. Generally, automatic transmissions have gears such as P, R, N, D, 2, 1, or L. 6AT indicates six forward gears, meaning there are six sets of gear groups with different transmission ratios. Others include 4AT, 8AT, 9AT, and even 10AT. Although the preceding numbers differ, they are all derivatives of automatic transmission technology.

What are the symptoms of a broken clutch cable?

Damage to the clutch cable can result in symptoms such as clutch slippage, vibration, and abnormal noises. Below are the related symptoms of a damaged clutch cable: 1. Clutch slippage: When starting the car in a low gear, after releasing the clutch pedal, the car fails to start or has difficulty starting; during acceleration, the speed does not increase with the engine RPM, making the car feel underpowered. In severe cases, a burning smell or smoke may occur. 2. Incomplete clutch disengagement: When the clutch pedal is fully depressed, the power between the clutch driven plates cannot be completely cut off, leading to difficulties in shifting gears, gear grinding, inability to stop, or clutch overheating. 3. Clutch vibration: During startup, the entire vehicle shakes, especially when idling and gradually releasing the clutch pedal in low gear, resulting in continuous jerking. 4. Abnormal clutch noise: When the clutch pedal is slightly depressed, as the inner end of the release bearing just contacts the release lever, the clutch emits a continuous "click, click, click" sound; noise accompanied by shaking occurs during startup or while disengaging while driving.
