Tire pressure warning light coming on when the tires appear fine indicates that the pressure in the four tires is outside the normal range. This is usually caused by slow air leakage due to a puncture or overinflated tires. It is recommended to check all four tires to see which one is low on air. If it's not obvious, drive to a repair shop to have the tire pressure checked. If a tire is found to have low pressure, it means there is a leak, and it should be repaired. Hazards of overinflated tires: Reduced friction and adhesion, affecting braking performance; causes steering wheel vibration and veering, reducing driving comfort; accelerates wear on the central tread pattern, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; Excessive stretching of tire cords, reducing tire elasticity and increasing the load on the vehicle while driving; decreases puncture resistance. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, leading to internal cracks or blowouts.

What are the dimensions for parallel parking in driving school?

Parallel parking standard dimensions are as follows: 1. Large vehicle parking space: Width 4 meters, length 7 to 10 meters (varies by vehicle model). 2. Compact vehicle parking space: Width 2.2 to 2.5 meters, length 5 meters. 3. Adjacent road dimensions: Single-side parking requires 5 meters width, double-side 6 meters, large vehicles 8 meters. Additional information: Parallel parking is a key assessment point in the Category 2 driving test, designed to train drivers in properly parking vehicles along roadside spaces or garages to meet temporary parking needs in daily driving situations. The primary objective is to equip learners with skills for correctly positioning vehicles in roadside parking spots.

How to deal with a small dent in the sheet metal?

It may not have been handled properly during repair, and small dents should be repaired immediately. Here is more information about sheet metal repair: 1. Sheet metal repair can restore small dents caused by collisions on car doors, returning the deformed and dented door to its original shape. 2. Sheet metal repair is currently the most effective solution for damaged car doors. After sheet metal repair, the vehicle needs to be repainted because the metal panels may experience paint wear or peeling due to tool operations. After repair, the door panels will become smooth. 3. Sheet metal repair involves a significant amount of work and requires professional auto repair shops or 4S stores to perform the repair.

What do the numbers and the letter W on tires mean?

Tire numbers sequentially represent the tire's section width, aspect ratio, tire type code, rim diameter, load index, and speed rating. The letter W on a tire indicates its speed rating, with W corresponding to a speed rating of 270 kilometers per hour. Tire specifications are commonly represented by a set of numbers, where the first number indicates the tire's section width and the second number indicates the rim diameter, both measured in inches. Taking 215/60R1795H as an example, 215 refers to the tire width of 215mm, 60 refers to the aspect ratio, R indicates a radial tire, 17 means the tire diameter is 17 inches, 95 represents the load index, and H is the speed rating.

At what temperature gauge reading should you stop or drive at low speed?

When the temperature gauge reading reaches 100 degrees, you should stop or drive at low speed. Here are the details: 1. Introduction: The car temperature gauge usually has two letters, C and H, or uses white and red zones to indicate. C stands for cold, and H stands for hot. If the temperature gauge approaches the H or the red danger zone, and the temperature warning light comes on in severe cases, it indicates that the engine coolant is too high. 2. How the temperature gauge works: The sensor of the temperature gauge is a thermistor-type sensor. It is fixed to the engine cooling water passage with threads. The thermistor determines the current flowing through the coil winding of the temperature gauge, thereby driving the pointer to swing. In the past, tap water was used as the cooling water for car engines. Now, many car engine cooling systems use special coolant. Therefore, it is also called the coolant temperature gauge.

Can a water-soaked car dry out on its own?

Car soaked in water cannot dry out on its own. Here is relevant information: 1. Classification: There are two types of insurance related to vehicle water immersion—the most common one is vehicle damage insurance, and the other is called engine special loss insurance, commonly known as water immersion insurance. 2. Insurance compensation: The scope of water immersion insurance is relatively narrow, generally covering various expenses incurred when the engine is submerged in water under normal driving conditions, provided that the vehicle is not restarted after the engine is flooded. However, relatively few people opt for water immersion insurance. Currently, the main insurance that covers compensation for natural disasters such as heavy rain is vehicle damage insurance, which can basically cover all vehicle losses. If a vehicle is soaked in water, as long as the engine is not flooded and only parts replacement or circuit repairs are needed, these fall under the coverage of vehicle damage insurance.
