What Causes Uneven Tire Pressure?

The reason for uneven tire pressure is: each tire experiences slightly different driving conditions, especially in summer when the side exposed to sunlight has a higher temperature, resulting in slightly higher tire pressure. Additionally, ground friction coefficients and minor variations during inflation for each tire contribute to the differences. As long as the discrepancy is not significant, it is not a problem. Factors affecting tire pressure: 1. Seasonal factors: In winter, it is advisable to increase the standard tire pressure by 0.2bar appropriately, while in summer, when the car is parked outdoors, the pressure can be 0.1bar lower than the standard to prevent blowouts due to high temperatures; 2. Tire pressure measurement environment: The tire pressure of a cold tire differs from that of a hot tire, and the difference should be noted to be around 0.3bar when measuring.

Why Does the Car Fan Keep Running After the Engine Is Turned Off?

The reasons why the car fan keeps running after the engine is turned off are: 1. The higher the coolant temperature after parking; 2. Short circuit in the fan motor or control circuit; 3. Damage to the water temperature sensor or stuck contacts of the fan relay. The function of the fan is: to increase the air velocity through the radiator core, enhance the cooling effect, and accelerate the cooling of water. The solutions for a car fan that keeps running after the engine is turned off include: 1. Wait for ten minutes to observe whether the fan continues to run; 2. Conduct a comprehensive inspection of the cooling system; 3. Unplug the fan wiring harness for separate power-off treatment; 4. Go to a repair shop to replace the sensor or relay with a new one.

Will Water Enter the Car When Parking Uphill on a Slope During Rain?

Parking uphill on a slope during rain will not cause water to enter the car. Here are the relevant details: 1. Hazards of parking on a slope: Damage to the handbrake braking system; Impact on the suspension; Risk of the car rolling; Increased likelihood of scraping accidents. 2. Harm caused by rainwater to the vehicle: Paint aging and corrosion; Corrosion of the chassis; Moisture and mold inside the car; Breeding of bacteria; Impact on electrical circuits, damaging the engine; Damage to headlights, etc. The chassis can be eroded by acid rain. Thunderstorm weather can also lead to water accumulation on the road. After the vehicle passes through waterlogged areas, acidic rainwater can adhere to the chassis. Retention of acid rain on the chassis can lead to rusting of the chassis.

Should the Dashcam's G-Sensor Be Enabled?

Dashcam's G-sensor can be enabled, but it is recommended to set it to a low sensitivity option and regularly format the memory card to prevent the card from storing too many non-overwritable videos, which would reduce the available space for loop recording. The G-sensor, also known as collision detection storage, works by the dashcam's CPU detecting when the values from the gravity sensor exceed the preset threshold, at which point it assumes a collision has occurred and protects the current video segment from deletion, thereby achieving the function of automatically storing footage during collisions. A dashcam is an instrument that records images, sounds, and other relevant information during vehicle operation. It can utilize high-definition lenses to comprehensively document driving footage, audio, and vehicle status data.

Should You Use High Beams or Low Beams When Driving in the Rain?

When driving in the rain, use low beams along with position lights, and turn on fog lights when the rain is heavy. High beams can create a dazzling glare in rainy or foggy conditions, affecting surrounding vehicles, so they should not be used. Hazard lights should also not be used indiscriminately while driving; they should only be activated when parked or during emergency braking. Tips for driving in the rain: 1. Before heading out, check if the windshield wipers are functioning properly and clearing water effectively; 2. If fog forms on the windshield, quickly turn on the defroster or air conditioning to maintain clear visibility; 3. Reduce speed and maintain a safe distance from the vehicle ahead when driving on wet or slippery roads; 4. Slow down before turning, appropriately increase the turning radius, and steer gently to prevent loss of vehicle control.
