Standard tires require 2.4-2.5 bar, while reinforced tires need 2.8-2.9 bar. Below is relevant information about tire pressure: 1. Introduction to tire pressure: Strictly speaking, tire pressure refers to the air pressure inside the tire. In automotive maintenance, the engine is the heart of the car—its failure means the end of the car's life—while tire pressure is like the car's blood pressure. The level of tire pressure plays a crucial role in the car's performance and power. 2. Importance of maintaining proper tire pressure: Excessive tire pressure reduces friction and adhesion, affecting braking performance; it causes steering wheel vibration and deviation, reducing driving comfort; it accelerates wear on the central tread pattern, shortening tire lifespan. Insufficient tire pressure increases the friction coefficient with the road surface, raising fuel consumption; it makes the steering wheel heavy and prone to deviation, creating factors that compromise driving safety.

As a seasoned driver, I believe maintaining proper tire pressure is crucial. The general recommendation is between 30-35 PSI. For instance, my family car stays stable year-round at 32 PSI. Don't underestimate this – insufficient pressure leads to faster tire wear and increased fuel consumption. I've even experienced a scary blowout incident. Overinflation makes the ride uncomfortably bumpy and significantly reduces traction. I make it a habit to check monthly using a household pressure gauge, especially in winter when temperatures drop quickly – topping up promptly saves trouble. Remember to check the door frame sticker or manual and follow the guidelines. Safety comes first – this small detail safeguards family trips. Once it becomes routine, your car will last longer with fewer worries.

Where is the daytime running light switch for the CS75?

cs75 daytime running lights do not have an independent switch. When the Changan CS75 vehicle is started, the daytime running lights will automatically turn on. Daytime running lights are lamps that make the vehicle more easily recognizable during daytime driving. These lamps are not for illumination but serve as signal lights. Daytime running lights can improve visibility and make the vehicle more conspicuous. This technology, specifically researched for daytime use, is more direct and effective than existing lighting devices. If equipped with daytime running lights, road users can detect and recognize the vehicle earlier and better. In the dark, if the driver turns on the regular headlights, the daytime running lights will automatically turn off. The CS75 has a body length, width, and height of 4650mm, 1850mm, and 1695mm respectively, with a wheelbase of 2700mm.

Is It Normal for the Rear Wheels to Have Uneven Gaps Between the Wheel and the Wheel Arch?

It is not normal for the rear wheels to have uneven gaps between the wheel and the wheel arch. One side being higher than the other could be due to a significant difference in tire pressure between the left and right sides, excessive load on one side of the vehicle, or a damaged shock absorber on one side. A vehicle with one side higher than the other can compromise its balance and stability. In such cases, it is necessary to promptly identify the cause of the issue and carry out repairs. A significant difference in tire pressure between the two sides is also a common issue. In this case, it is necessary to check whether the tires are damaged or leaking. If a tire is damaged or leaking, it needs to be replaced. It is best to replace a pair of tires at the same time. Replacing only one tire may also affect the driving experience. Excessive load on one side of the vehicle can also cause the body to be higher on one side than the other. This is often due to the shock absorber system reaching the end of its lifespan. At this point, the shock absorber system can no longer provide sufficient support for the vehicle. The solution is to replace the shock absorbers and springs. In vehicles that have been in use for a long time, the shock absorber system is prone to failure. Common issues with the shock absorber system include oil leakage from the shock absorbers and loss of elasticity in the shock absorber springs. Both of these problems can lead to insufficient support from the shock absorber system, resulting in uneven height on both sides of the vehicle. The solution is to replace the shock absorber system.

What does the red key warning light on the dashboard mean?

The reasons for the red key warning light on the dashboard: There are two types of dashboard key flashing red lights. One type does not have a KEY symbol and is the engine immobilizer indicator light. If this light is on, it indicates a fault in the anti-theft system, and you should take your car to a 4S shop or auto repair shop for inspection. The other type has a KEY symbol, which indicates that the car key battery is low. You should check it immediately to determine whether the battery needs to be replaced. If the battery is low, it should be replaced as soon as possible to avoid inconvenience in using the car. The dashboard is a rigid panel or structural component used to install instruments and related devices. It can be classified into screen-type dashboards, frame-type dashboards, channel-type dashboards, and cabinet-type dashboards. Some indicators and warning lights are also included.

Why Does Brake Fluid Need to Be Replaced?

Brake fluid needs to be replaced because: after a certain period of use, the boiling point of brake fluid decreases, it becomes contaminated, and undergoes varying degrees of oxidation and deterioration. Brake fluid absorbs moisture from the air, and the hydraulic braking system must allow the brake fluid to be exposed to the atmosphere to function properly. Over time, the brake fluid absorbs moisture, which turns into bubbles under high temperatures. When bubbles form in the brake fluid lines, braking efficiency decreases. Therefore, brake fluid should be regularly checked for quality and performance based on climate, operating environment, seasonal changes, and working conditions, and replaced on schedule. Brake fluid should generally be replaced every two years or 50,000 kilometers. When selecting brake fluid, different types should not be mixed to avoid chemical reactions that could affect braking performance.

Why is a car considered totaled after being submerged in water?

It is not always the case that a car is considered totaled after being submerged in water. Here are the relevant details: 1. Water-crossing vehicle: Water reaches the wheels, but the interior remains dry. This is commonly referred to as a water-crossing situation, which is relatively common and generally causes no damage to the vehicle. 2. Water-damaged vehicle: Water reaches halfway up the wheels, and the interior is flooded up to below the dashboard (generally called a water-damaged vehicle). This situation causes damage to the vehicle's performance, but with professional treatment, the car can still be used. 3. Flood-damaged vehicle: The water level exceeds the wheels, and the interior is flooded up to the dashboard (generally called a flood-damaged vehicle). In such cases, the water level has already caused severe damage to the engine, transmission, and electrical systems, and it is not recommended to continue using the vehicle even after repairs.
