The TC warning light being on is usually caused by accidentally turning off the traction control switch next to the gear shift lever. Simply turn the switch back on to resolve the issue. If the possibility of accidental switch deactivation by the driver is ruled out, it indicates a malfunction in the traction control system, and the vehicle should be promptly taken to a repair shop for inspection. The traction control system is designed to ensure stable traction under various driving conditions. An illuminated TC light signifies a fault in the traction control system, which could be due to issues such as a faulty solenoid valve, dirty engine oil clogging the solenoid valve filter screen, or wear in the actuator gears and impeller leading to oil pressure leakage. These conditions can all result in traction control system malfunctions. Additionally, a dirty throttle body with an opening reaching 20% may cause the engine control unit to misdiagnose a TC system fault.

Will the back seat of a private car be fined for not wearing a seat belt?

Fine. The following is an introduction to the penalties for not wearing a seat belt in the back seat: 1. Introduction 1: Whether the back seat will be fined for not wearing a seat belt varies from city to city. Taking Shenzhen as an example, the back seat in Shenzhen will be fined for not wearing a seat belt. Since July 4, 2016, the Shenzhen traffic police have strictly investigated the behavior of passengers not wearing seat belts. If the back seat passengers do not wear seat belts, the driver will also be punished. Whether it is the front seat passengers or the back seat passengers, as long as they do not wear seat belts according to the regulations, the driver will face a fine and 2 points deduction. 2. Introduction 2: As for the regulation that "the driver is punished for the passenger's violation," the Shenzhen traffic police's attitude is very clear. The driver is the person responsible for driving safety. The driver must not drive a motor vehicle when the passengers do not use the seat belt as required. If the passengers do not wear seat belts, the traffic police will punish the driver according to the law.

How Long Does It Take to Charge a Car After the Battery Dies?

When a car battery is dead, the car engine needs to maintain a speed of over 2000 RPM, and the car must be driven for at least 4 hours to fully recharge the battery. Here are the specific details about car batteries: 1. Function: The battery stores electrical energy. Without it, the car cannot operate normally. 2. Charging while driving: Typically, household car batteries are 12V, with a no-load voltage around 13V and a load voltage not lower than 11V. If the voltage drops below this level, it may cause difficulty in starting the car. The battery can be charged by the alternator while the car is running. If the car is parked for an extended period, the battery may lose its charge, making it difficult to start the car. Therefore, during long-term parking, it is recommended to start the car at least once a week for more than 5 minutes to recharge the battery. 3. Charging precautions: Generally, it takes 4-5 hours to fully charge the battery, and overcharging should be avoided.

What is the Function of a Car Air Conditioner?

Car air conditioners primarily function in temperature regulation, humidity regulation, and airflow regulation. Temperature Regulation: This is the main function of a car air conditioner. In summer, the cooling system generates cold air to lower the temperature inside the cabin; in winter, except for large commercial vehicles that use independent combustion heaters for warmth, most other vehicles utilize residual heat from the engine for heating. Humidity Regulation: Humidity significantly affects the thermal comfort of passengers inside the car. The humidity inside the cabin should generally be maintained between 30% and 70%. Standard car air conditioners do not have the capability to regulate cabin humidity; this can only be achieved through ventilation systems or advanced luxury cars equipped with integrated heating and cooling air conditioners. Airflow Regulation: The speed and direction of airflow greatly influence passenger comfort. If the air is blowing directly, the speed should be limited to a certain range when the temperature is appropriate. The airflow speed can be adjusted based on passengers' living environment, age, health condition, and personal preferences regarding temperature.

How to use the rear wiper switch of the Tiguan L?

The rear wiper switch of the Tiguan is located on the wiper lever on the right side of the steering wheel. It controls the rear wiper by pushing or pulling the lever, along with the front wiper. More details about wipers are as follows: 1. Wipers, also known as windshield wipers, are devices used to wipe away raindrops and dust attached to the vehicle's windshield to improve the driver's visibility and enhance driving safety. Due to legal requirements, almost all cars are equipped with wipers. Rear windows of hatchbacks and SUVs are also fitted with wipers. 2. There are generally two types of wipers: the traditional intermittent type, which is the most common wiper with three to four segments, allowing the driver to adjust according to the rain intensity and visibility conditions; and the rain-sensing type, mostly used in mid-to-high-end models. A good wiper must be heat-resistant, cold-resistant, acid and alkali-resistant, corrosion-resistant, able to fit the windshield, reduce the motor's burden, produce low noise, have strong water-repellency, and be soft enough not to scratch the windshield, ensuring clear vision for the driver. 3. Maintenance personnel recommend replacing the wipers annually to ensure driving safety.

How Many Meter Models Are There for Concrete Pump Trucks?

Concrete pump trucks come in 7 length specifications: 21 meters, 24 meters, 28 meters, 30 meters, 33 meters, 38 meters, and 35 meters. Different pump truck models are designed based on requirements such as chassis dimensions, mixer efficiency, and boom length. For instance, while maintaining other configurations of a 33-meter pump truck unchanged, optimizing the boom design and adjusting the overall layout can lead to the development of a 35-meter concrete mixing pump truck. Additional information: 1. Boom height: Based on boom height, concrete pump trucks can be categorized into short boom (13-28 meters), long boom (31-47 meters), and ultra-long boom (51-62 meters). Currently, short and long boom models are most common in the market. 2. Theoretical output: Pump trucks can be divided into three types by output capacity: small (44-87 m³/h), medium (90-130 m³/h), and large (150-204 m³/h). 3. Pumping pressure: This refers to the concrete pressure at the pump outlet during operation. Classification includes low pressure (2.5-5.0 MPa), medium pressure (6.1-8.5 MPa), high pressure (10.0-18.0 MPa), and ultra-high pressure (22.0 MPa).

What documents and certificates are required for new car delivery?

The required documents include the car purchase invoice, compulsory traffic insurance policy, owner's ID card (non-local owners need to provide residence permit), and vehicle qualification certificate. In addition to the above documents, you also need the vehicle purchase tax certificate, engine and chassis number rubbing strips, and original factory photos of the vehicle. Car delivery precautions: 1. Body paint surface: Check the flatness of body steel plates and bumpers, which should not have abnormal protrusions or depressions. Carefully inspect all paint surfaces, especially areas prone to scratches during transportation. The exterior color should be coordinated, uniform, full, flat, and smooth, without pinholes, pits, wrinkles, bubbles, flow marks, or scratches. 2. Interior: Door windows should move up and down freely, reaching the top when raised and the bottom when lowered. Front seats should move forward and backward freely with multiple fixed positions for passengers to choose appropriate seating positions. Door panels and interior trim should be properly installed and not loose when pushed. 3. Tires: Check if tires are complete, if rims are clean and perfect, without protrusions or scratches. Also inquire about or measure tire pressure to ensure normal pressure and equal pressure in all four tires. Additionally, push and pull the upper side of the tire from the side to check for looseness. For disc brakes, inspect if the brake discs are complete without significant wear or dirt.
