What is the difference between buying a car from a 4S store and an auto trade store?

The main differences between buying a car from a 4S store and an auto trade store are: 1. Price-wise, 4S stores tend to be more expensive. Auto trade stores are not subject to manufacturer price controls and adjust prices based entirely on the market. Moreover, due to lower operating costs, auto trade stores can adopt a small-profit quick-turnover strategy. 2. Vehicle sources: Auto trade stores source their cars from 4S stores, while 4S stores receive vehicles directly from manufacturers. 4S stores can only sell cars of a single brand, whereas auto trade stores can sell multiple brands. 3. Quality assurance: 4S stores generally provide better quality guarantees. The likelihood of purchasing inventory cars or problematic vehicles from auto trade stores is significantly higher than from 4S stores. 4. After-sales service: 4S stores are more reliable in this aspect.

How to Charge a Car Battery Quickly?

Car battery charging can be accelerated by using fast charging methods. A car battery, also known as a storage battery, is a type of battery that works by converting chemical energy into electrical energy. Precautions for charging a car battery include: 1. In cold weather, check if the electrolyte is frozen before charging; do not charge a frozen battery. 2. Before charging, check the electrolyte level; do not charge if the electrolyte is insufficient. 3. During charging, measure the density and voltage of the electrolyte approximately every hour and monitor its temperature. 4. Ensure the charging area is well-ventilated and strictly prohibit open flames. 5. Stop charging if unattended.

Are Rearview Mirror Rain Guards Actually Useful?

Rearview mirror rain guards are useful as they prevent the mirrors from becoming blurry during rainy weather. To install, clean the mounting area thoroughly, attach the rain guard using 3M adhesive tape, and press firmly. The car's rearview mirrors display conditions behind, beside, and below the vehicle, allowing the driver to indirectly view these areas. They function as "eyes in the back," expanding the driver's field of vision and assisting in road condition awareness during driving, making them crucial components of a vehicle. Here are specific details about rearview mirrors: 1. Without rearview mirrors, driving would be disastrous for the driver. Maneuvers like turning, making U-turns, or overtaking become extremely hazardous without their assistance. 2. During rain, drivers must view the rearview mirror through the side window glass and the mirror itself. The multiple layers of obstruction combined with rain interference make it difficult to see clearly, introducing safety risks. Thus, ensuring clear visibility through rearview mirrors in rainy conditions is particularly important. 3. Many car owners opt to install rain guards on their rearview mirrors to mitigate rain-related visibility issues. Adding rain guards is indeed a simple and practical solution. As a traditional rain prevention method, rain guards offer some effectiveness. They work well in light rain but may still be less effective during heavy rainfall. Additionally, rain guards can affect the vehicle's aesthetics and may interfere with the rearview mirror's adjustability.

What does the teapot symbol on the car dashboard mean?

The teapot symbol on the car dashboard refers to the engine oil warning light. The reasons for its illumination are: 1. Insufficient engine oil level; 2. Engine temperature is too high; 3. Oil pump wear causing abnormal operation; 4. Improper internal engine coordination; 5. Excessive carbon deposits clogging the oil filter; 6. Pressure relief valve set pressure is too low or improperly adjusted. Engine oil, also known as engine lubricant, is composed of base oil and additives. It serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine. The method to reset the oil light is: 1. Turn off the ignition switch and hold the set button; 2. Turn on the ignition switch and press the button on the left side of the instrument panel.

Should You Shift to Neutral When Starting on a Slope?

Starting on a slope requires shifting to neutral. Steps for stopping at a designated point on an uphill slope: Upon hearing the instruction "stop at the designated point on the uphill slope," turn on the right turn signal and steer the vehicle toward the right side of the road. As you approach the roadside, slightly turn the steering wheel to the left, then quickly straighten it to the right to align the right side of the vehicle parallel to the roadside, maintaining a distance within 50 cm (using the white line of the parking spot ahead as a reference, do not cross the white line). Press the clutch and slowly approach the stopping point. When the midpoint of the right fender aligns with the parking sign, press the brake, stop the car, and pull the handbrake (until you hear two clicks). Turn off the turn signal. Before starting, shift to 1st gear, turn on the left turn signal, and honk the horn once. Slowly release the clutch while holding the handbrake lever, ready to start at any moment. When you feel the car shaking or hear gear engagement sounds, release the handbrake, and the car will move forward. Method for starting on a slope: The key to starting on a slope is clutch control. Use the centerline of the car hood as a marker to align the vehicle parallel to the lane lines on both sides. Use the lower right corner of the windshield and the marker pole on the right side of the solid line on the slope as two main reference points. When driving up the slope, look through the windshield. When the distance between the marker pole and the lower right corner of the windshield is 25 to 30 cm, brake and then pull the handbrake. Taller drivers should have a shorter distance, no less than 25 cm. When starting on the slope, press the clutch and shift to 1st gear. Slowly release the clutch—releasing it too quickly may cause the car to stall. When you feel the car shaking the most, keep the clutch position steady, release the handbrake, and the car will start moving. Practice is needed to gauge the shaking amplitude, as insufficient shaking may cause the car to roll backward.
