In a car, 'KEY' refers to the key. Vehicles equipped with smart keys will display a 'KEY' indicator light on the dashboard if the car cannot detect the key (either the smart key is not inside the car or is not within the effective range). Here are some solutions for when you lose your car key: 1. Spare key: Generally, cars nowadays come with two keys, one for regular use and the other as a spare. 2. Professional locksmith: If the spare key is far away or also lost, you will need to call a professional locksmith to unlock the car. 3. 4S shop: Every car comes with an anti-theft code. The owner can provide the vehicle license and identification information to the 4S shop, which can then retrieve the anti-theft code based on the provided information and configure a new key. Additionally, the data of the lost key can be erased, meaning the lost key will become invalid and unable to start the car, though it may still open the doors. Therefore, the 4S shop may also recommend replacing all the locks in the car to ensure security.

Honestly, when people ask me what a car key means, I feel like it's just talking about the 'key' in daily car life. Back when I first bought my car, the key was simple—just a small metal piece you inserted into the door. But now, there are more variations. It's not just for unlocking doors; it's also a security tool. For example, pressing a remote key can flash the lights and honk the horn, while a smart key automatically unlocks when you're near the car—super convenient. Some keys even come with chips that the engine recognizes to start, preventing theft. If the key breaks or runs out of battery, like when the remote range shortens, you'll need to replace the battery or visit a repair shop for a new key. I always advise beginners to first check the manual to understand their key type and avoid tampering with settings. A friend at the dealership said maintaining the key is crucial—regular cleaning to prevent rust and avoiding high-temperature areas can extend its lifespan.

Should You Repair or Replace a Tire with a Nail Puncture?

Tire puncture caused by a nail can be either repaired or replaced, depending on the location of the puncture and the depth of penetration. Here are the details: Nail puncture on the tire sidewall must be replaced: The tire sidewall is the most vulnerable part of the tire. If a nail punctures the sidewall, the overall toughness and safety performance of the tire will be greatly reduced. Therefore, if the sidewall is punctured by a nail, the tire should be replaced immediately. Damage exceeding 6mm must be replaced: Regardless of where the nail punctures the tire, if the damaged area exceeds 6mm, even after repair, it can easily lead to secondary air leakage and the risk of a blowout, posing a significant safety hazard. Therefore, it is recommended to replace the tire directly.

How Much Fuel Should Be Added to a New Car?

When refueling a new car, stop when the fuel nozzle automatically shuts off. Here are some precautions for refueling a car: Refuel according to the fuel tank capacity: The fuel tank capacity indicated in the vehicle's user manual is smaller than the actual capacity of the tank because it represents the safe capacity (i.e., the maximum reasonable volume). Therefore, the amount of fuel added should not exceed this safe capacity. As long as you do not exceed the safe capacity indicated in the manual, you can add as much fuel as you want. Refuel based on the remaining fuel level: One important point to note is that you should refuel when the fuel level drops to 1/4 of the tank's capacity. If you wait until the tank is almost empty before refueling, the accumulated impurities at the bottom of the tank can be drawn into the fuel system, leading to poor fuel supply.

Should the clutch be pressed when decelerating in Subject 3?

Subject 3 deceleration does not require pressing the clutch, which should only be used in emergency situations. The following are precautions for deceleration during the Subject 3 test: Scenarios requiring deceleration: In many regions, voice announcements no longer remind candidates of special areas such as school zones, bus stops, and crosswalks. However, candidates must perform corresponding deceleration or yielding operations based on the project signs and road markings. Correct deceleration method: First, release the accelerator with the right foot, then lightly press the brake for 2 seconds (pressing too briefly may not be recognized). Only press the brake without the clutch, and downshift appropriately based on the situation after deceleration.

What does the R inside a tire mean?

The R in the tire model refers to the tire being a radial tire. Radial tires are named after the internal cord fabric arrangement direction, which forms a 90-degree angle with the tread centerline, resembling the meridians on a globe. Below is a detailed introduction to radial tires: Characteristics of radial tires: The crown part of radial tires is reinforced with steel belts, allowing them to withstand greater internal pressure stress. They feature less tread deformation, better ground grip, and stability, making them more suitable for high-speed driving. Nowadays, passenger cars commonly use radial tires. Meaning of tire model codes: Tire types have internationally standardized tire codes, expressed in millimeters to indicate the section width and the percentage of the aspect ratio. These are followed by the tire type code, rim diameter (in inches), load index (permissible load mass code), and permissible speed code.
