What to Pay Attention to When Buying a Used Car in the US

When buying a used car in the US, check the vehicle's durability report, choose through standardized channels, research the car's condition online, estimate the transaction price by checking market prices, inspect and test drive the car carefully during in-person transactions, and ensure proper insurance and registration. Check the vehicle's durability report: Most used car dealerships or websites provide durability reports for their vehicles. It's important to review the most reliable durability reports, which contain detailed repair data from repair shops, offering direct reference value when selecting a used car. Choose through standardized channels: Either purchase directly from a dealership or buy from the owner. Research the car's condition online: Pay special attention to the vehicle's exact condition, including the number of previous owners, detailed engine specifications and displacement, accident history, production records, mileage records, maintenance history, and transaction history. Estimate the transaction price by checking market prices: Use authoritative used car valuation websites to check prices for different makes and models, helping estimate the transaction price and compare it with your budget. Inspect and test drive the car carefully during in-person transactions: During in-person transactions, thoroughly examine the engine and transmission. Verify that the engine's production number matches the vehicle's body, check for excessive noise during cold starts, and look for signs of transmission fluid leaks. Additionally, test the braking performance for stability and reliability—these are critical aspects of the inspection process and should be done carefully.

Will points be deducted for making a U-turn over a crosswalk?

Making a U-turn over a crosswalk will result in point deductions, as it is considered a traffic violation. According to Article 49 of the 'Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China': Motor vehicles are not allowed to make U-turns at locations with signs or markings prohibiting U-turns or left turns, as well as at railway crossings, pedestrian crosswalks, bridges, sharp curves, steep slopes, tunnels, or other sections of the road where accidents are prone to occur. Definition of yielding to pedestrians at crosswalks: Pedestrians walking on the right side of the crosswalk who have not reached the centerline of the road. Vehicles on the left side of the road should slow down and proceed cautiously, ensuring safety while allowing pedestrians to cross. Pedestrians waiting outside the boundary line between motorized and non-motorized lanes. If they have not entered the roadway, vehicles should slow down and proceed cautiously, ensuring safety while allowing pedestrians to cross. If pedestrians cross the dividing line between motorized and non-motorized lanes, vehicles failing to stop and yield is a violation and should be penalized. When pedestrians enter the motorized lane from the crosswalk, vehicles should slow down and proceed cautiously, ensuring safety while allowing pedestrians to cross. If vehicles fail to stop and yield, it is a violation and should be penalized. Pedestrians waiting at the centerline of the road without entering the motorized lane. Vehicles failing to stop and yield is a violation and should be penalized. Pedestrians crossing the centerline of the road and entering the motorized lane. Vehicles failing to stop and yield is a violation and should be penalized. When pedestrians are separated by a green belt in the middle of the road and are waiting in the median area, vehicles must slow down and proceed cautiously, ensuring safety while allowing pedestrians to cross. Permissible U-turn situations: Intersections with U-turn signs: If there is a clear U-turn sign at an intersection, a U-turn is permitted. If there is a U-turn traffic light, follow its instructions. If there is no traffic light, proceed with the U-turn based on the specific situation, ensuring it does not interfere with other vehicles or pedestrians. Intersections without explicit prohibitions on U-turns or left turns: If there are no signs explicitly prohibiting U-turns, a U-turn is allowed. 'No explicit prohibition' means the absence of 'No U-turn' or 'No left turn' signs and no solid centerline, allowing for a U-turn. Yellow grid lines also permit U-turns: Yellow grid lines are no-parking zones marked at intersections prone to congestion due to temporary stops, important entrances, or other designated areas. Stopping on these lines (including waiting for traffic lights) is a violation. Although parking is prohibited in yellow grid zones, U-turns are allowed. If there is no central barrier, yellow grid lines are equivalent to 'U-turn permitted.' When 'No left turn' and 'U-turn permitted' signs appear together: U-turns are allowed, but left turns are prohibited. However, 'No U-turn' does not mean 'No left turn.' Precautions when making U-turns at intersections: Observe road markings. If they are solid lines, U-turns are prohibited under any circumstances. Continue driving to find a suitable location for a U-turn. If there is a 'No left turn' sign ahead, even if there is no mention of prohibiting U-turns, U-turns are not allowed at that intersection because U-turns inherently involve a left turn. U-turns must be made from the innermost left-turn lane. If in the second left-turn lane, U-turns are not permitted at that intersection. Always yield to oncoming traffic when making a U-turn. Proceed only if it does not interfere with the normal flow of traffic; otherwise, you will bear full responsibility for any accidents. Near the stop line at intersections, lanes often have guiding arrows indicating permitted movements. The leftmost lane is not always for left turns; if it has a straight arrow, U-turns are prohibited even without explicit 'No U-turn' signs.

What does ECON mean in vehicle air conditioning?

The ECON in car air conditioning is actually a mode of the air conditioning system, which only takes effect when the air conditioning is turned on for cooling. The air conditioning compressor is driven by the engine and can consume up to 20% of the engine's power. After activating the ECON mode, the vehicle will reduce the power consumption of the air conditioning while ensuring its effectiveness, thereby achieving fuel savings. The method to turn on the air conditioning's economy mode is very simple: the owner just needs to press the "Econ" button after turning on the air conditioning. When the light on the button is on, the air conditioning cooling system is turned off, and only natural air or warm air is provided. Here is an introduction to the ECON mode of car air conditioning: Usually, car air conditioning has an A/C symbol to indicate whether the air conditioning is on or off, representing the economy mode of the air conditioning. In this state, the compressor also works. Compared to the normal mode, the control point of the compressor is raised, and the compressor does not remain engaged continuously during operation. The start and stop points of the compressor are controlled by the evaporation temperature. In normal mode, the compressor's start-stop point is between 2~4°C. In ECON mode, the compressor's start-stop point is between 8~10°C. The lower the temperature, the longer the compressor's working time and the greater its workload. Activating the ECON mode will save engine power output and conserve fuel. The functions of the car air conditioning: Using the continuous phase change cycle of the refrigerant to achieve cooling effects; Removing dust, odors, smoke, and toxic gases from the air inside the car to freshen the air, and humidifying the air inside the car to increase its relative humidity; Using the engine coolant, waste heat, or heat generated by a burner as a heat source for heating, which is then heated by a heater and blown into the car by a fan to raise the temperature at the air outlets for heating purposes; Drawing in fresh air from outside the car for ventilation and air exchange, which also helps prevent windshield fogging. Precautions for using air conditioning in the car: Do not set the air conditioning temperature too low. A large temperature difference between the inside and outside of the car can easily cause the driver to catch a cold, and excessively low temperatures may also increase the risk of arthritis for passengers. Control the direction of the air outlets. Based on the principle that cold air sinks and hot air rises, when using the air conditioning, set the air outlets upward when cooling and downward when heating. Do not turn on the air conditioning immediately after the car has been exposed to the sun. After exposure, the temperature inside the car will be very high. First, open the windows for ventilation, and then turn on the air conditioning after the hot air has been expelled.

What does the SPNFMI fault code mean?

SPNFMI fault code indicates excessive moisture in the vehicle's fuel filter. The solution is to drain the water from the fuel-water separator or replace the separator if necessary, while also checking for any sensor damage. When this issue occurs, the vehicle should not continue to be driven. Here's an introduction to fuel filters: Fuel filters can be categorized into three types - gasoline filters, diesel filters, and natural gas filters. The function of a fuel filter is to prevent particles, water, and impurities in the fuel from causing wear or other damage to the precision components of the fuel system.

What are the common causes of ABS pump damage?

ABS pump damage is commonly caused by frequent hard braking and emergency stops. Once this part is damaged, it is recommended that the owner promptly repair it. After the car's ABS pump is damaged, symptoms may include the ABS warning light turning on, the anti-lock braking function failing, and the brake pads not resetting. The following is an introduction to ABS: Car ABS refers to the Anti-lock Braking System. The function of car ABS is to automatically control the braking force during braking, preventing the wheels from locking up and maintaining a state of rolling and sliding (with a slip ratio of about 20%), ensuring maximum wheel-to-ground adhesion.

What Are the Uses of a Snorkel?

The functions of a snorkel: Increases the vehicle's wading depth; aids engine performance by allowing more efficient air intake. Additional details about snorkels are as follows: 1. The more official term for a snorkel is "high-mounted air intake" or "wading kit," which is essentially an extended air intake pipe. 2. Installing a snorkel significantly raises the engine's air intake position, ensuring that the engine does not ingest water during off-road wading, thus aiding engine performance and improving air intake efficiency. 3. When driving through water, a snorkel prevents water from entering the engine, avoiding potential engine failures.
