Car switches 'on' and 'off' represent turning on and off. Additionally, there are some other buttons in the car: 1. The 'SEL' button is the menu selection confirmation button, usually located on the multifunction steering wheel; 2. The 'AC' button is the compressor switch, which is the air conditioning cooling switch; 3. 'MUTE' is the mute button, allowing for one-touch muting; 4. 'MODE' is the mode switching button; 5. 'SET' on the multifunction steering wheel is the cruise control function button; 6. The button with an encircled 'A' and 'OFF' beneath it is the auto start-stop function switch, which can be pressed to turn the engine auto start-stop function on or off.

I've been driving for many years, and 'on' and 'off' are the two most common words you'll see on car switches. Simply put, 'on' means to activate a certain function, while 'off' means to deactivate it. For example, take the headlight switch: turn it to 'on' and the lights illuminate the road; switch it to 'off' and the lights go out, saving battery power. The same goes for the air conditioning button—press 'on' to start the cooling system and blow cold air, press 'off' to stop it and avoid draining power. The key thing to note is that forgetting to switch to 'off' when parking can lead to excessive battery discharge, potentially leaving you unable to start the car the next day. I've encountered this situation a few times myself, and repairing the battery after it's drained cost quite a bit. Nowadays, even though new cars come with automatic modes, it's still important to pay attention to the basic manual switches and develop good habits with their 'on/off' states. Don't underestimate this—it can extend the lifespan of your electrical components and save you a lot of hassle.

What transmission is used in the Changan CS75 PLUS 1.5T?

The transmission brand used in the Changan CS75 PLUS 1.5T is Aisin. Established in 1969, Aisin is a world-renowned professional developer and manufacturer of automotive automatic transmissions. In the field of automotive automatic transmissions, Aisin's products hold the world's highest market share. The Changan CS75 PLUS 1.5T is equipped with an Aisin 6-speed automatic transmission (6AT) with manual shift mode. The manual shift mode essentially adds manual gear-shifting functionality to traditional AT or CVT transmissions. The purpose of this feature is to enhance the driving pleasure of automatic transmission vehicles. For the transmission of the Changan CS75 PLUS 1.5T, the following points should be noted during daily use: Do not delay transmission fluid changes for extended periods. Prolonged failure to change transmission fluid can damage internal components such as bearings and the transmission housing. Avoid prolonged coasting in neutral. While driving manual transmission vehicles, many experienced drivers tend to coast in neutral. However, for automatic transmission vehicles, coasting in neutral can cause the transmission to overheat, and shifting back into D (Drive) mode may result in noticeable jerking. Never shift into D/R (Drive/Reverse) before the vehicle comes to a complete stop. Some drivers, aiming for "smooth" operation, shift directly into reverse while the vehicle is still moving. This can severely damage transmission gears and may lead to gear grinding or other malfunctions over time. Avoid frequently climbing steep slopes in D mode. When tackling steep inclines, automatic transmission vehicles may overheat due to high load or shift prematurely, resulting in insufficient power for climbing. In such situations, use manual mode to lock in lower gears or switch to sport mode to protect the transmission. Do not tow the vehicle over long distances. In case of a breakdown, an automatic transmission vehicle should be transported using a flatbed tow truck with the transmission in N (Neutral) mode. Never use tow ropes or attempt to tow the vehicle directly with another vehicle.

What is the actual fuel consumption of the BYD Qin?

Overall, the fuel consumption of the BYD Qin hybrid in economic mode is approximately 6L/100km. In electric mode, the range with a full charge is around 40+ km. On flat terrain, with gentle driving and good road conditions, achieving the nominal 70 km range in pure electric mode is no problem. Here are some related details: 1. Definition of fuel consumption: Fuel consumption refers to the amount of fuel consumed corresponding to the distance traveled by a vehicle. Constant-speed fuel consumption is an indicator of fuel economy when a car is driving at a constant speed on good road surfaces. The commonly mentioned "liters per 100 kilometers" means how many liters of fuel a car consumes for every 100 kilometers traveled, where "liters" is equivalent to "L" (liters). 2. Factors affecting fuel consumption: The level of a car's fuel consumption is related to many factors, including driving environment and driving habits. Examples include prolonged engine idling, emergency braking, inconsistent driving speeds, insufficient tire pressure, aggressive acceleration, and long-distance driving at high speeds in low gears. Additionally, road conditions have a significant impact on fuel consumption, especially in urban traffic conditions where traffic jams are common.

How Often Should a Honda Vehicle Undergo Major Maintenance?

According to Honda's maintenance schedule, a major maintenance service should be performed every 20,000 kilometers. Here are the relevant details: 1. Major maintenance content: Major maintenance refers to the routine service performed at the manufacturer-specified time or mileage, which includes replacing the engine oil, oil filter, air filter, and fuel filter. 2. Major maintenance intervals: Major maintenance is based on the existence of minor maintenance, and these two types of services are generally performed alternately. The intervals vary depending on the vehicle brand, so please follow the manufacturer's recommendations. 3. Items involved in major maintenance: In addition to replacing the engine oil and oil filter, there are two other items in a major maintenance service: (1) Air filter: The engine draws in a large amount of air during operation. If the air is not filtered, the dust in it can accelerate the wear of the piston group and cylinder. Larger particles entering between the piston and cylinder can also cause severe "cylinder scoring." The air filter's role is to remove dust and particles from the air, ensuring that sufficient, clean air enters the cylinder. (2) Fuel filter: The fuel filter's function is to provide clean fuel to the engine by filtering out water and impurities from the gasoline. This optimizes engine performance and provides the best protection for the engine.
