A tire pressure of 195 kPa is not normal. Driving with a tire pressure of 195 kPa is not advisable. The normal range for tire pressure is 230 to 250 kPa. When driving with insufficient tire pressure, the most noticeable effect is increased fuel consumption. Low tire pressure increases the contact area between the tire and the road, leading to greater friction and added driving resistance, which in turn increases fuel consumption. Additionally, insufficient tire pressure accelerates tire wear and reduces the tire's lifespan. The relationship between tire pressure and vehicle handling stability: Cornering stiffness is a crucial parameter that determines a vehicle's handling stability. Tires should have high cornering stiffness to ensure good handling stability. Tire pressure significantly affects cornering stiffness—the higher the tire pressure, the greater the cornering stiffness. However, beyond a certain point, increasing the pressure does not further change the stiffness. Introduction to standard tire pressure: According to the international standard GBT2978-2008, the recommended tire pressures are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: should not exceed 3.5 bar.

How to Drain the Windshield Washer Fluid in Baojun 310?

The most straightforward method is to spray it out using the windshield washer lever. Alternatively, you can drain the windshield washer fluid using the siphon principle. Here is a brief introduction about windshield washer fluid: 1. Origin of Windshield Washer Fluid: Windshield washer fluid is a vehicle-specific solution made from deionized water and various environmentally friendly additives. It functions to clean, repel water, prevent freezing, resist static electricity, and prevent corrosion. It effectively removes dust, lubricating oil, residual polishing wax, tree sap, bird droppings, and insect residue from highways. 2. Steps to Drain Windshield Washer Fluid in Baojun 310 Using the Siphon Principle: Open the hood, locate the windshield washer fluid reservoir cap, insert a 2-meter-long soft hose into it, pushing it as deep as possible. Then, connect the other end of the hose to a syringe, and extract the fluid from the reservoir. When the fluid level reaches a position equivalent to the headlights, remove the syringe, place the soft hose on the ground, and allow the windshield washer fluid to drain from the reservoir.

Will speeding always be captured by electronic eyes?

Speeding may not always be captured by electronic eyes. Here are the reasons why speeding may not necessarily be captured by electronic eyes: Traffic violation captures rely on electronic eyes, which depends on whether there are capture devices at the violation location. Additionally, it depends on whether the system or manual review identifies the violation. With increasingly advanced monitoring equipment, the accuracy of recognition is also improving, so it is essential to obey traffic rules. Here are two methods of vehicle violation capture: 1. Underground induction loops: Digital cameras are installed on crossbars to capture red-light running; 2. Installed cameras: Used for real-time recording of speeding, red-light running, illegal parking, etc. Here is an introduction to the review process after electronic eye capture: Violations captured by electronic eyes generally require manual review. For highway violations, the review process is usually faster, and sometimes the violation record can be checked the next day; for violations on ordinary roads, the process is slightly slower, and it may take until the third day to check the record.

Can the Dash Cam Continue Recording After the Car is Turned Off?

Whether the dash cam can continue recording after the car is turned off is explained as follows: If the dash cam is equipped with a parking monitoring function, it can continue recording after the vehicle is turned off, but the recording time is not long, as the dash cam cannot be charged when the vehicle is off. Additional information: 1. Classification of dash cams: The parking monitoring function of dash cams is divided into two types, one is full-time recording, and the other is short-time recording that only starts when the vehicle is shaken. However, there is no dash cam that can continuously and persistently record after the car is turned off. 2. Working time of dash cams: Dash cams operate using the car's power during the day, and when the vehicle is turned off, the dash cam stops working. Although many dash cams come with built-in batteries, some batteries can only last for four or five hours at most, while others can only maintain power for about half an hour. Therefore, generally, dash cams cannot continue recording for a long time after the car is parked and turned off.

What is the fuel consumption of the Corolla at idle speed?

The comprehensive fuel consumption of the Corolla is 4.0-5.6L/100km. There are a total of 12 models of the Corolla currently on sale. The E-CVT Pioneer version has a fuel consumption of 4L/100km. The E-CVT Elite version and E-CVT Flagship version have a fuel consumption of 4.1L/100km. The CVT Pioneer version has a fuel consumption of 5.1L/100km. The CVT Elite version, CVT Elite CARE version, and SPORT version have a fuel consumption of 5.2L/100km. The Pioneer PLUS version has a fuel consumption of 5.5L/100km. The Elite PLUS version, Flagship version, Luxury version, and Manual Pioneer version have a fuel consumption of 5.6L/100km. The above figures are NEDC comprehensive fuel consumption, which is the fuel consumption data measured under the NEDC test procedure. The actual fuel consumption ranges from 2.0-10.5L/100km. Here are 5 tips to help reduce fuel consumption while driving: When starting the vehicle, use a low gear, gently press the accelerator, and accelerate slowly. Avoid suddenly pressing the accelerator hard, as this can multiply fuel consumption. Light acceleration, light braking, and early braking: While driving, gently press the accelerator to avoid sudden increases in engine RPM and prevent the car from shaking, which helps save fuel. By anticipating road conditions and applying slow, even acceleration or braking, fuel economy can be improved by up to 20%. Maintain proper tire pressure: Keep tire pressure at the level recommended by the manufacturer. For every 2 PSI below the recommended value (equivalent to about 0.2 in metric units relative to the standard pressure of 2.4), fuel consumption increases by 1%. Regular maintenance or vehicle inspection: Timely oil changes can reduce carbon buildup (carbon deposits can cause ignition issues, sluggish acceleration, increased fuel consumption, and in severe cases, even cylinder misfires). Regularly check and replace the air filter if dirty, and clean or replace the fuel injectors, spark plugs, and throttle body as per the recommended mileage. Close windows while driving. Driving with windows open increases wind resistance, which in turn increases the resistance the car faces, requiring more power and thus increasing fuel consumption. To summarize, the following tips can help reduce fuel consumption while driving: Start in a low gear, press the accelerator gently, maintain proper tire pressure, perform regular maintenance or vehicle inspections, and close windows while driving.

What Does the Car Tire Pressure Warning Icon Look Like?

Tire pressure monitoring indicator is a yellow symbol, an irregular circle with no seal on top and four small spikes at the bottom, containing an exclamation mark inside. The illumination of the tire pressure monitoring indicator indicates abnormal tire pressure. Abnormal tire pressure generally has the following three causes: Abnormal tire pressure: It usually triggers an alarm when the pressure is below 1.8 bar or above 3.0 bar. At this time, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the tire pressure monitoring system will still record the previous data, causing the tire pressure monitoring indicator to light up. In this case, simply reset the tire pressure. Damaged tire pressure sensor: The tire pressure sensor is used to monitor tire pressure and is directly installed inside the tire, connected to the tire inflation port. If the tire pressure sensor is damaged due to impact while driving, it will also cause the tire pressure warning light to illuminate. For sensor damage issues, only replacement with a new component is possible.
