What is the normal tire pressure for cars in winter?

In winter, the standard tire pressure for regular tires is generally between 2.6-2.7 bar, while reinforced tires have a tire pressure range of 3.0-3.1 bar. Due to seasonal factors, winter tire pressure typically increases by about 0.2 bar. You can check the tire pressure using a tire pressure monitoring system (TPMS). TPMS automatically monitors the tire pressure in real-time while driving and alerts you to tire leaks or low pressure to ensure driving safety. If the tire pressure monitoring indicator light comes on (a yellow symbol with an irregular circle, no stamp on top, four small spikes at the bottom, and an exclamation mark inside), there are generally three possible reasons: 1. Abnormal tire pressure. The system usually triggers an alarm if the pressure is below 1.8 bar or above 3.0 bar. In this case, you need to inspect the tires and adjust the pressure. 2. The tire pressure monitoring system has not been reset. After inflating the tires, if the system isn't reset promptly, it may still display the old data, causing the indicator light to stay on. Simply reset the tire pressure monitoring system to resolve this issue. 3. A faulty tire pressure sensor. The sensor, installed inside the tire and connected to the inflation valve, monitors tire pressure. If the sensor is damaged during driving (e.g., due to impact), the tire pressure warning light may illuminate. In such cases, the only solution is to replace the sensor with a new one.

In winter, the normal tire pressure range for sedans is around 32 to 35 PSI, but this should be based on your vehicle's manual. For every 10-degree drop in temperature, tire pressure decreases by about 1-2 PSI, so check more frequently in cold weather. It's recommended to measure with a tire pressure gauge once a week, using readings from a cold tire. If the pressure is too low, tires are prone to deformation, slipping, and poor braking; if too high, the center of the tire wears out faster and can cause loss of control on slippery winter roads. I've seen a friend who, eager to save fuel, ended up with overinflated tires leading to a blowout. For safety, make it a habit: check right after parking, and if it's below 32, add air—don’t wait for problems to arise. Also, new cars usually come with a tire pressure monitoring light—don’t ignore it when it lights up. It can save you from accident repair costs and extend your tire’s lifespan by several years.

How to Deal with the Urea Fault Light on HOWO China V Vehicles?

Use a diagnostic tool to read the fault code. This situation may be caused by severe urea crystal blockage. Removing and cleaning the exhaust elbow pipe can resolve the fault. It is necessary to inspect the vent of the urea tank and the water heating valve of the urea tank. If the water heating valve is damaged, replacing it will eliminate the fault.

Where is the emergency release switch for the Sagitar fuel tank cap?

The Sagitar fuel tank cap is located on the right side of the vehicle body. Press the fuel tank cap lightly when the vehicle is unlocked to open it. For most cars, the fuel filler port is located on the left rear or right rear side. Therefore, finding the correct direction of the fuel filler port essentially means identifying which side of the vehicle it is on.

What is the method for removing the rear air vents of the Tiguan?

The air vents are generally installed on the dashboard using snap-fit connections. To remove them, tools that can be used for prying are usually required. If you prefer not to pry, you can press down and then pull forward to easily remove the vent. Some air vents are located near the central control display or audio system, so consideration should be given to whether these components also need to be removed during the process.

How to Read the Coolant Temperature Gauge on a Skoda Fabia?

The coolant temperature gauge is located below the tachometer on the left side of the instrument panel. The pointer moves clockwise from the left along a semicircle to the right, with the corresponding scale indicating the coolant temperature. As long as the pointer is within the normal scale range, the temperature is considered normal. The pointer entering the red zone indicates overheating. Generally, using the manufacturer-recommended coolant (antifreeze) is sufficient. Do not arbitrarily add water to the radiator.
