According to different brands, the distance may vary. Generally, at a speed not exceeding 80KM/H, it can drive about 80 kilometers. The following is a detailed introduction about run-flat tires: 1. Definition: The scientific name of run-flat tires is "Run-flat System Component", abbreviated as RSC. It usually consists of an outer tire, a common inner tube, a spare inner tube, a steel rim, a gas generator (or gas storage chamber), a pressure sensor, and a control unit. 2. Working principle: The reason why run-flat tires do not collapse after losing air is mainly due to the thickened rubber sidewall. Even if the air pressure is lost, the sidewall can still support the weight of the vehicle without causing severe deformation. Therefore, a flat tire does not seriously affect the vehicle's driving, and the owner may not even feel it.

What Do the Indicator Lights on the Car Dashboard Represent?

Car dashboard indicator lights are divided into three categories. Below is a detailed introduction to the indicator lights on the car dashboard: 1. Indicator Lights: The most common lights while driving, such as light signal indicators, turn signal indicators, parking lights, etc. Their function is to indicate the status of various vehicle functions. 2. Warning Lights: These have a warning function, such as the fuel indicator light, door status indicator light, seat belt indicator light, etc. Generally, warning lights turn off after the driver performs the corresponding action, for example, the seat belt indicator light turns off after the seat belt is fastened. 3. Fault Lights: The most important indicator lights, such as the generator fault indicator light, ABS fault indicator light, transmission fault indicator light, etc. Normally, these fault lights rarely illuminate, or they may light up briefly when starting the engine and then turn off. If a fault light remains lit and is accompanied by a warning sound, it indicates that the vehicle has a fault or abnormality. Never underestimate fault lights; ignoring them could potentially damage the vehicle and seriously endanger driving safety. If a fault light remains lit, immediate inspection and repair are required.

Will I be penalized for driving at 75 in a 70 speed limit zone?

If the speed limit is 70 km/h, driving at 75 km/h will not result in penalty points. The penalties and point deductions for speeding by ordinary vehicles are as follows: 1. No penalty: Speeding within 10% of the prescribed speed limit will not be penalized. 2. Penalty cases: Exceeding the prescribed speed limit by more than 10% but less than 20% will result in a fine of 200 yuan and 3 penalty points. Exceeding by more than 20% but less than 30% will result in a fine of 200 yuan and 6 penalty points. Exceeding by more than 30% but less than 50% will result in a fine of 200 yuan and 6 penalty points.

What are the effects of not changing spark plugs for a long time on a car?

Not changing spark plugs for a long time can directly cause various problems such as leakage in the vehicle's ignition system, vehicle shaking, increased fuel consumption, difficulty in acceleration, and reduced power. The most significant issue is difficulty in ignition, which affects the normal use of the vehicle. Typically, the service life of a spark plug is 15,000 kilometers, while long-life spark plugs can last up to 30,000 kilometers. The purpose of a spark plug is to ignite. During use, the electrodes of the spark plug consume electricity through spark discharge, especially when the center electrode reaches a higher temperature and is consumed by acidification. The amount of electrode consumption varies based on the melting point, strength, and hardness of the electrode material. To reduce this consumption, materials such as nickel alloy, platinum, or iridium are used in the electrodes, which can extend the lifespan even with very fine electrodes. Timely replacement of spark plugs ensures complete combustion of gasoline, thereby achieving optimal power and reducing fuel consumption.

What is the reason why the Mercedes-Benz S400 hybrid cannot start?

The reasons why the Mercedes-Benz S400 hybrid cannot start include: 1. Mechanical damage to the throttle front drive mechanism; 2. Missing engine speed signal; 3. Collision signal in the ignition sequence; 4. Insufficient battery power; 5. Low fuel pressure; 6. Engine system failure. When the car cannot start, first check the car's voltage. If the battery voltage is sufficient, it indicates that the battery is working normally. Then check the car's fuel pressure gauge. If the fuel pressure gauge is normal, it may be due to insufficient battery power or engine failure. It could also be that the car computer has generated a fault code. After the fault code appears, it is necessary to go to a 4S store and use professional equipment for inspection. The corresponding fault needs to be repaired before the fault code generated by the car computer can be cleared. The dimensions of the Mercedes-Benz S400 are 5230 mm in length, 1871 mm in width, and 1485 mm in height.

Can the Car Pickup Be Postponed for Several Months After Ordering?

After placing an order for a car, it is possible to postpone the pickup for several months, provided that you discuss and agree with the dealer in advance. Normally, when ordering a car from a 4S store, the pickup can be expected within one month. However, due to various factors at the 4S store, the pickup time may be extended significantly, sometimes up to three months. Below are some key considerations when picking up the car: 1. Required documents: purchase invoice, vehicle certification, vehicle conformity certificate, motor vehicle registration certificate, warranty certificate, vehicle user manual, and new car delivery confirmation form. If the 4S store is responsible for license plate registration and insurance processing, you will also need to collect the original insurance policy, insurance invoice, compulsory traffic insurance invoice, vehicle and vessel tax invoice, purchase tax invoice, tax payment certificate, and compulsory traffic insurance label from the salesperson. 2. Thoroughly inspect the vehicle: Exterior checks should include the paint, production date of the window glass, tires, trunk, and engine. For the interior, focus on checking the functionality of features such as lights, wipers, windows, rearview mirrors, dashboard, air conditioning, and audio system.
