What is the appropriate tire pressure for SUV vehicles?

SUV vehicle tire pressure should be maintained at 2.5 bar. In summer, the tire pressure should be between 2.3 and 2.4 bar, as higher pressure combined with high road temperatures may increase the risk of a tire blowout. In winter, a tire pressure of 2.5 bar is suitable. Strictly speaking, tire pressure refers to the air pressure inside the tire. There is a label on the rear of the driver's side door indicating the standard tire pressure, which refers to the pressure when the tire is cold—meaning the vehicle has been parked for at least three hours or driven no more than 1.6 km. Measuring tire pressure when the tire is cold provides the most accurate reading. Below is relevant information about vehicle tire pressure: Hazards of excessive tire pressure: 1. Reduced friction and adhesion of the tire, affecting braking performance. 2. Causes steering wheel vibration and deviation, reducing driving comfort. 3. Accelerates wear on the central tread pattern of the tire, shortening its lifespan. 4. Increases vehicle vibration, indirectly affecting the lifespan of other components. 5. Overstretches the tire cords, reducing the elasticity of the tire body and increasing the load on the vehicle during driving. 6. Decreases resistance to punctures, making it easier for sharp objects like nails or glass to penetrate the tire, leading to internal cracks or blowouts. Hazards of insufficient tire pressure: 1. Increases friction with the road surface, leading to higher fuel consumption. 2. Makes the steering wheel heavy and prone to deviation, compromising driving safety. 3. Increases movement in various parts of the tire, causing abnormal heat due to excessive rolling. 4. Reduces the functionality of the cords and rubber, leading to delamination or cord breakage, and excessive friction with the rim, damaging the tire bead area and causing abnormal wear. 5. Multiplies friction between the tire and the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving under such conditions may result in a blowout. 6. Low tire pressure increases tire body deformation, making the sidewalls prone to cracking and causing flexing movements, leading to excessive heat, rubber aging, cord fatigue, and breakage, while also increasing the tire's contact area and accelerating shoulder wear.

Does Using Toothpaste to Clean the Car Harm the Glass?

Toothpaste can harm the car glass when used for cleaning. Toothpaste is typically composed of many substances with abrasive properties, such as calcium hydrogen phosphate, calcium carbonate, silicon dioxide, calcium pyrophosphate, and aluminum hydroxide. These substances give toothpaste its friction function. If toothpaste is used to clean glass, under light, you can see numerous fine scratches. The correct method to clean car glass is to pour car glass cleaner into a spray bottle and evenly spray it on the interior glass. If you're concerned that the sprayed cleaner might affect other parts of the car, you can cover them with a cloth or plastic beforehand. Then, use a clean, soft towel to wipe the glass. For car glass maintenance, it's important to completely remove any dirt from the glass. The defogging and heating function should be turned off after 5 to 10 minutes to prevent the rear window from cracking. After replacing the glass, avoid washing the car for two days and try to drive on flat roads. If the wipers do not fit tightly against the glass, they can cause scratches and impair functionality, so regular maintenance or replacement is necessary. Also, regularly replace the rubber seals to prevent leaks due to aging.

How often should a sedan be started if not driven?

It is recommended to start the car once a month and drive for 3-5 kilometers. If the vehicle remains idle for an extended period, such as not being driven for 2 months, it will definitely cause adverse effects. This can lead to uneven deformation of the tires. The reason is actually quite simple. A car is like a human being - merely staying stationary is insufficient. Regular exercise is necessary to maintain good health. When a vehicle is parked for a long time, the most critical component affected is the battery. Even when not in use, the battery will self-discharge. Typically, a battery can be completely discharged within 3 months, so it's advisable to remove the battery when the car won't be used for an extended period. Otherwise, the electrical appliances in the car will still consume power. Failing to do so may require you to seek a repair shop or another vehicle for a jump-start after just 10 days. The main issues with prolonged vehicle storage are: the battery may become depleted from lack of charging, making it difficult to start the car; and the tires, which bear weight at fixed contact points, may develop uneven deformation over time. Therefore, it's generally best to start the car approximately every two weeks and drive it for about 3-5 kilometers. This allows the battery to recharge and shifts the weight-bearing points of the tires for the next parking period, preventing these issues.

What are the symptoms of poor battery contact?

Symptoms of poor battery contact in a car include overheating battery terminals or sparking. Poor battery contact can lead to unstable idling, damage to the battery, and may also harm the generator. The main grounding wire from the battery to the car body is a thick power ground wire, usually connected to the car frame, which carries the current flow from various parts of the vehicle. Additional information is as follows: 1. Cause: Due to the battery terminals being prone to corrosion and sulfation, this grounding wire often has poor contact with the battery. Poor engine grounding can result in the starter and generator not working properly, and sensors failing to detect accurate signals. The spark plugs may not produce strong sparks, directly affecting the engine's power. Loose grounding points can also cause sparks, and the resulting arcs can damage components. 2. How to determine poor battery contact: From the positive terminal of the battery, one wire is directly connected to the starter, and another is connected to various electrical devices via a current-limiting chip and fuses. If the starter can operate but most electrical devices do not work, it may be due to a blown current-limiting chip. However, if the entire electrical system loses function, it could be due to poor contact at the battery terminals or loose cables.

When driving on the highway, if the driver does not use the seatbelt as required, a fine of more than 50 yuan will be imposed, and 2 points will be deducted. 2. When driving on urban expressways, if the driver does not use the seatbelt as required, a fine of more than 50 yuan will be imposed, and 2 points will be deducted. 3. When a vehicle is traveling on the highway, if the passenger does not wear the seatbelt as required, a fine of more than 20 yuan will be imposed. 4. When driving on roads other than highways or urban expressways, if the driver does not use the seatbelt as required, a fine of more than 50 yuan will be imposed, but no points will be deducted. 5. When driving a motor vehicle on urban roads with a speed limit below 50 km/h, if the passenger does not wear the seatbelt as required but corrects the behavior immediately after being pointed out, an oral warning will be issued. 6. According to the Road Traffic Safety Law, when a motor vehicle is in motion, the front passenger must also wear a seatbelt. The regulation requiring the front passenger to wear a seatbelt has been clearly stipulated in the old traffic rules. For any front passenger who does not wear a seatbelt, the on-duty traffic police can impose a fine of 20 yuan.
