What Should You Know About Being a Car Salesperson?

To be a car salesperson, you should know how to combine the car products you are selling with an understanding of the competition. Below is a relevant introduction regarding considerations when buying a car: 1. Determine your budget: When buying a car, first determine your budget range and reasonably estimate your financial capability. Avoid blindly choosing high-priced cars that exceed your financial capacity. The cost of the car, plus insurance and routine maintenance, can be a significant expense. Act within your means to prevent the car from becoming a burden. If you are not in a hurry to buy, it's best to choose a time when car prices are lower and market prices are stable, typically during the off-season from March to August. 2. Inspection upon delivery: When picking up the car, pay attention to the body gaps and paintwork. Check the door gaps and the gaps on the front and rear bumpers. Open the doors to observe if there is any color difference between the interior and exterior paint. Inside the car, check the odometer reading, whether the seat protective packaging and the plastic sheets on the dashboard are intact, and if there are any stains on the seats or dashboard. Also, note if there is a significant gap between the manufacturing date and the delivery date. If the gap is too long, the car might be a display model or a refurbished vehicle (test drive car). Start the car to feel its operating condition, such as any unusual noises or if any warning lights are on.

How Long Can a Car Be Driven Continuously?

Continuous driving of a car should not exceed four hours. According to Article 62 of the 'Regulations for the Implementation of the Road Traffic Safety Law': If driving a motor vehicle continuously for more than 4 hours, the driver must stop to rest, with a rest period of no less than 20 minutes. According to the 'New Traffic Regulations on Driver's License Deduction Rules': Driving a medium-sized or larger passenger vehicle or a hazardous materials transport vehicle continuously for more than 4 hours without stopping to rest or with a rest period of less than 20 minutes will result in a 12-point deduction. Driving any other motor vehicle continuously for more than 4 hours without stopping to rest or with a rest period of less than 20 minutes will result in a 6-point deduction. The main causes of driving fatigue are as follows: Sleep quality: Going to bed too late, insufficient sleep time; poor sleep quality; noisy sleep environment that affects sleep quality; Vehicle environment: Poor air quality, inadequate ventilation; excessively high or low temperatures; severe noise and vibration; improperly adjusted seats; Driving experience: Low skill level, unfamiliarity with operations; short driving time, lack of experience; poor safety awareness. Hazards of fatigue driving: Driving fatigue affects the driver's attention, sensation, perception, thinking, judgment, willpower, decision-making, and movement. When fatigued, drivers may experience blurred vision, soreness in the back and waist, stiff movements, weakness in limbs, slow reactions, lack of concentration, reduced judgment, increased operational errors, and even unsafe factors such as mental haziness or momentary memory loss. If the driver continues to drive under these conditions, it can easily lead to traffic accidents.

What is the aoff button?

This is the off button for the auto start-stop system, where 'off' means to turn off. Cars equipped with the auto start-stop function have an off button, and pressing it can deactivate the auto start-stop. The off button for the auto start-stop is a circle with an 'A' inside and 'off' below the circle, indicating the deactivation of the auto start-stop. Cars with the auto start-stop function will shut off the engine when stopped at a red light, provided the battery has sufficient charge and the engine coolant has reached normal operating temperature. If the battery charge is insufficient, the auto start-stop system will not function, and the system's indicator light on the dashboard will flash yellow. If the system is operational, the indicator will flash green. When the aoff light is on, it means the vehicle's engine auto start-stop function is active. This function effectively protects the engine from damage, reduces fuel consumption, and is very practical. The aoff button is primarily used when the car is moving at low speeds or repeatedly stopping, helping to automatically shut off the engine, reduce idle time, and consequently minimize engine carbon buildup. For the auto start-stop function to work, certain conditions must be met: the engine coolant temperature must reach at least 85 degrees Celsius, and the engine oil must also reach operating temperature. After the car starts, the auto start-stop function enters the active mode. For example, when approaching a traffic light, stopping and pressing the brake for 1 to 2 seconds will automatically shut off the engine. To restart when the light turns green, lightly press the accelerator or turn the steering wheel, and the engine will start again. In some manual transmission cars, the computer determines the need to shut off the engine based on actions like pressing the clutch, shifting to neutral, and pulling the handbrake. The engine will restart when the clutch is pressed again. However, in congested traffic when moving slowly, reversing into a parking space, or on steep slopes, you may choose to turn off this function. When driving through water, always remember to turn off this function to prevent water from entering the exhaust pipe and then the engine, which could prevent the engine from starting. Precautions for auto start-stop: Avoid using the start-stop system on slopes; Turn off the system during irregular stop-and-go traffic; Do not activate the system when the air conditioning is on; Disable the system during low-speed parking; Do not refuel when the start-stop system has shut off the engine; It is advisable to turn off the system when the fuel light is on; Always deactivate the system when driving through water.

What is the fuel consumption of the Changan CS95 four-wheel drive?

The Changan CS95 four-wheel drive has 2 models on sale, including the Changan CS95-2021-2.0T-Four-wheel Drive Premium and Four-wheel Drive Luxury models, both equipped with a 233 horsepower engine, with an NEDC fuel consumption of 9.4L per 100 kilometers. The fuel tank capacity of different Changan CS95 models is the same. The distance that can be covered with a full tank of fuel is as follows: For models equipped with a 233 horsepower engine, the fuel tank capacity is 74L, and the distance that can be covered with a full tank of fuel is 74/9.4*100=787KM. The fuel consumption of a car is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. Specific factors that can increase car fuel consumption are as follows: Driving habits: Aggressive driving, such as sudden acceleration, frequent overtaking, and not easing off the throttle before a red light, can increase fuel consumption. The car itself: Cars with larger displacements consume more fuel than those with smaller displacements because larger displacements generally mean higher power, requiring more gasoline to burn and perform work. Cars with greater weight consume more fuel because greater weight requires larger driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases car resistance and fuel consumption. Low environmental temperature: When the engine block temperature is low, the gasoline injected during a cold start does not atomize easily, requiring more gasoline to be injected for combustion, which increases fuel consumption. Additionally, at low temperatures, the engine computer controls the engine to run at higher RPMs to warm up, which also increases fuel consumption.

What is the mileage for vehicles that need to replace the timing belt?

It is generally recommended to replace the car's timing belt every 80,000 to 100,000 kilometers. If the timing belt is not replaced by 200,000 kilometers, there is a risk of breakage. Since the timing belt is made of rubber, it naturally ages over time with use. If it continues to be used for an extended period, it may break, leading to engine failure. Here is some additional information: 1. Regular inspection and replacement: The timing belt operates at high speeds for long periods, inevitably leading to wear and tear. As a consumable part, it requires regular replacement. Regularly check the belt surface for cracks and signs of wear. If the wear is severe or cracks are present, it should be replaced promptly. If not replaced, continued use may result in breakage. Once the belt breaks, the engine may produce abnormal noises, the vehicle may stall, and it can cause valve damage. In severe cases, it may lead to engine component damage, rendering the engine inoperable and making the car unusable. 2. New car belt replacement cycle: For new cars, the timing belt can be replaced after 100,000 to 130,000 kilometers, but this depends on the actual usage of the vehicle. If the car is often driven without heavy loads, it can be inspected at 80,000 kilometers, and if no issues are found, it can continue to be used until replacement at 100,000 to 130,000 kilometers. If the car is frequently driven under heavy loads, causing greater belt wear, it should be inspected around 60,000 to 80,000 kilometers and replaced around 100,000 kilometers.

Is 92 or 95 Octane Gasoline Better?

95 octane gasoline is better than 92 octane gasoline. Generally speaking, the higher the octane rating of gasoline, the higher the octane number and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. In addition to checking the appropriate gasoline grade in the car manual, you can also check it on the fuel tank cap, which will also be marked. Usually, you can also decide the gasoline grade based on the engine's compression ratio. Cars with an engine compression ratio between 8.6-9.9 should use 92 octane gasoline, while cars with an engine compression ratio between 10.0-11.5 should use 95 octane gasoline. If the compression ratio is higher, 98 octane gasoline should be used. However, with the use of some new technologies, the gasoline grade cannot be determined solely based on the compression ratio. A high compression ratio can also be adjusted to use lower octane gasoline. This is because, in addition to the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Occasionally using the wrong gasoline grade only requires switching back to the correct grade after use. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended for low octane gasoline, using higher octane gasoline will not cause damage, but the increase in octane number will change the fuel's ignition point, leading to delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, resulting in poorer performance. For vehicles recommended for high octane gasoline, using lower octane gasoline can cause engine knocking. Because the octane number is too low, the gasoline's ignition point decreases, causing it to ignite prematurely during the compression stroke. If combustion occurs before the spark plug ignites during the compression stroke, resistance will occur during the upward stroke. This resistance will make the engine run very unstably. If it is only mild knocking, the noise will increase, but the damage to the engine is not significant. If there is obvious knocking, it indicates the engine's condition is very severe. The vibration not only affects driving stability but also causes abnormal wear on the piston and cylinder, and in severe cases, cylinder scoring.
