The reasons for the car display screen not lighting up are as follows: 1. The battery cable was removed when the car left the factory and was reconnected upon delivery; check if the cable connection is loose. 2. First, check if the fuse is blown. 3. Check if the ribbon cable is loose. 4. Check if the backlight bulb is burned out; generally, the bulb power supply is 12V. 5. If the bulb is not damaged, check if the power supply chip for the LCD bulb on the motherboard is faulty. Solutions for a car display screen that does not light up and is unresponsive to touch: 1. If the DVD freezes during operation, causing the car display screen to go black and become unresponsive to touch, restart the power supply of the car display screen. 2. Third-party software is incompatible with the system; check if any new software has been downloaded recently. Freezing may be caused by unstable programs or insufficient memory. In this case, free up some memory and uninstall the related software. 3. If it is a hardware issue, you can only take the car to a 4S shop for maintenance or to a repair shop for inspection. 4. Check if the software version is outdated or not updated in time, which may cause the display screen to malfunction. If so, simply upgrade the software version. 5. Finally, if many methods have been tried and none work, you can only perform a car inspection and replace the navigation device.

What is the fuel tank capacity of the Baojun 730 in liters?

The fuel tank capacity of the Baojun 730 is 52 liters, as officially announced. Owners who have purchased the Baojun 730 can also check this information on the vehicle's configuration sheet. The Baojun 730 uses 92-octane fuel, with a fuel consumption of 6.8 to 7.6L per 100 kilometers. A full tank can cover a distance of approximately 684 to 765 kilometers. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically done by observing the fuel gauge inside the vehicle. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when only 2 segments remain to avoid running out of fuel midway. In actual refueling situations, the amount of fuel added may exceed the marked capacity. This is because the manufacturer's specified tank capacity is measured from the bottom of the tank to the safety limit, and there is additional space from the safety limit to the tank opening. This extra space ensures that the fuel can expand when temperatures rise without overflowing. If fuel is filled up to the tank opening during refueling, the actual amount added may exceed the marked capacity.

Is a Used Kia Carens Worth Buying?

Used Kia Carens is also worth purchasing. Kia Carens Powertrain: In terms of power and handling, the Kia Carens is equipped with a 2.0L engine, delivering a maximum power of 152 horsepower and a peak torque of 194 Nm. The steering wheel offers a refined feel with adjustable steering effort, though the force feedback is somewhat excessive. The Sport mode is not particularly user-friendly. The throttle response is brisk, maintaining good acceleration consistency throughout, with no noticeable power drop-off in the mid-to-high speed range. The brake pedal feels slightly heavy, which can be tiring in congested traffic. Advantages of the Kia Carens: As a newer MPV model, it remains relatively niche—a decent imported vehicle that hasn't gained strong sales traction in China. One reason is the lagging domestic demand for MPVs, as consumers prefer SUVs, even opting for cramped 7-seat SUVs over MPVs, possibly because non-premium MPVs lack perceived prestige. Another factor is the Kia Carens' slightly higher manufacturer's suggested retail price (MSRP), which weakens its competitiveness compared to rivals.

Should You Release the Handbrake or Shift Gear First in an Automatic Transmission?

When starting an automatic transmission vehicle, you should shift into gear first and then release the handbrake, as this is the safest operating sequence. Of course, whether you shift gear first or release the handbrake first will not have any impact on the vehicle's transmission components. The purpose of releasing the handbrake last is to prevent the vehicle from rolling. The specific steps for starting the vehicle after getting in are as follows: 1. Insert the key into the ignition switch, press the brake pedal to start the vehicle, and release the brake pedal after the engine starts. Wait for 1 minute. 2. In winter, you may extend this time slightly to allow the engine to be fully lubricated. During this time, you can fasten your seatbelt, adjust your seat, check the dashboard for any abnormal warnings, and ensure the rearview mirrors provide good visibility. Turn on the appropriate lights if necessary. Then, press the brake pedal, shift into gear, and finally release the handbrake. After checking the surrounding environment, you can release the brake pedal and prepare to start moving. 3. Developing such a good starting habit ensures that even in urgent situations, you will instinctively complete this series of actions, reducing the risk of danger.

Where is the engine number of Volkswagen Sagitar located?

For the Volkswagen Sagitar 1.4T, the engine number is located at the junction between the engine and the transmission. To access it, you need to remove the air intake inlet and the air intake box, but the battery does not need to be disconnected. A wide-mouth pliers is required to remove the clip connecting the intake duct to the air box. After removal, the engine number will be visible. Additional information: 1. The engine number is stamped on a relatively flat surface of the engine block, consisting of a combination of letters and numbers. Due to the narrow space, it may be difficult to observe, so cleaning the surface dust may help. 2. When registering and licensing the vehicle, the engine number needs to be imprinted. Some regions use red oil for imprinting, while others use white paper. Specific requirements vary by region, so it's advisable to clarify before imprinting. 3. The engine number is like the engine's ID card, with uniqueness and traceability. Once registered, the engine has legal effect, entitling rights while requiring obligations to prevent illegal modifications and unauthorized use. Moreover, within a 30-year cycle, no two engine numbers are the same until the vehicle is deregistered upon scrapping.

What is the best engine oil for Geely Vision?

According to the manufacturer's manual requirements, the Geely Vision should use engine oil of the following grades: 1. Summer: 20W-50 and 15W-40 - API SJ or SL multi-grade oil. 2. Winter: 10W-30 and 5W-30 - API SJ or SL multi-grade oil. Here is some extended information about engine oil: 1. The "0W-30" on the engine oil packaging label refers to the oil's viscosity grade, which is classified according to the SAE standard. The "W" stands for winter, and the smaller the number before it, the better the oil's low-temperature fluidity, indicating a lower usable environmental temperature and better engine protection during cold starts. The higher the number after it, the higher the oil's viscosity at high temperatures, providing better lubrication for the engine. 2. It is recommended to use fully synthetic oil. Semi-synthetic and fully synthetic oils are two categories of engine oil. The main difference between them is that fully synthetic oil can be used over a wider temperature range and has a longer service life. For the same oil film requirements, fully synthetic oil can achieve the desired performance with a lower viscosity, whereas semi-synthetic oil requires a relatively higher viscosity to meet the same requirements.
