The yellow TC light with a slash in the Envision is the Traction Control System indicator. Press the button below the gear shift mechanism, then turn off the ignition and restart to reset the system, and the yellow TC light with a slash will turn off. If the warning light remains on or lights up again while driving, repairs are needed. Possible causes for the TC light to illuminate include: solenoid valve failure; dirty oil clogging the solenoid valve filter; wear on the actuator gear and impeller, leading to oil pressure leakage and triggering the alarm; dirty throttle with an opening reaching 20%; or the engine computer misjudging a TC fault. The working principle of the Traction Control System involves replacing the mechanical connection between the accelerator pedal and the throttle with an electronic throttle device. Sensors transmit the accelerator pedal's information to the ECU, which then generates a control voltage signal based on this information. The motor adjusts the throttle according to the signal, thereby reducing the throttle opening and controlling wheel slip. For drivers operating vehicles in rainy or snowy conditions, this can help reduce occurrences of wheel slip or loss of control.

Can a motorcycle still be inspected after 6 years of overdue inspection?

A motorcycle that has not been inspected for 6 years cannot participate in the annual inspection. If a motorcycle has not been inspected for 3 consecutive inspection cycles, it will be deregistered. Driving a vehicle with an overdue inspection is illegal and may result in a warning from the public security traffic management department. Motorcycle inspection schedule: For motorcycles within 6 years of registration, inspection must be applied for every 2 years at the public security traffic management department to obtain the inspection compliance label; motorcycles over 6 years old must be inspected annually. Motorcycle inspection process: For the motorcycle inspection, basic identification documents must be brought, and the motorcycle must be driven to the designated vehicle inspection site on a working day for registration and inspection. The motorcycle inspection mainly covers three aspects: the braking system, the lighting system, and exhaust emissions. Motorcycle overdue inspection: If the motorcycle inspection is overdue for less than 3 months, it can be directly rectified, usually with a verbal warning; if overdue for more than 3 months but less than 2 years, rectification may involve an unspecified fine. If the inspection is overdue for more than 2 years, the vehicle's registration will be directly canceled. Once the inspection is overdue, the vehicle owner will be fully liable for any accidents.

What is the Difference Between Commercial and Non-commercial Vehicles?

Commercial and non-commercial vehicles are primarily distinguished by whether they are used for profit-making purposes. A commercial motor vehicle refers to a vehicle engaged in road transport operations for profit-making purposes, meaning it generates and obtains economic benefits through transport activities related to business operations. Examples include taxis, chartered minibuses, private large dump trucks, and small trucks. In short, commercial motor vehicles are those used for profit-making purposes, such as transporting passengers or goods. Non-commercial motor vehicles are those not used for profit-making purposes. Generally, private cars and company-owned vehicles fall under this category. Non-commercial vehicles cannot participate in commercial transport activities. The vehicle registration certificate specifies whether a vehicle is commercial or non-commercial. There are no special requirements for the driver's license, but if you drive a commercial vehicle, you must obtain a professional qualification certificate from the transport department. This is not required for non-commercial vehicles. The "use nature" section of the registration certificate for commercial vehicles will state "commercial," and the vehicle must obtain a road transport permit from the transport management department. In addition to holding a driver's license for the specific vehicle type, the driver must also obtain a professional qualification certificate. Commercial vehicles are required to pay regular transport management fees to the transport management department. Non-commercial vehicles do not incur any transport management fees and thus do not need to pay such fees. The "use nature" section of their registration certificate will state "non-commercial," and they do not require a road transport permit. Drivers only need a valid driver's license for the specific vehicle type.

How many points are deducted for not wearing a seat belt while driving?

When driving on urban expressways, if the driver fails to use the seat belt as required, they will be fined and have 2 points deducted. When driving on roads other than highways or urban expressways, if the driver fails to use the seat belt as required, they will be fined but no points will be deducted. Passengers who do not wear seat belts as required will also be fined. Below is an introduction to seat belts: Types of seat belts: high-altitude work type, semi-full-body type, bungee equipment type, and automotive type. Function of seat belts: The function of automotive seat belts is to instantly tighten and secure the loosely worn seat belt when a vehicle collision occurs or emergency braking is applied, firmly restraining the occupant in the seat to prevent secondary collisions. Once the tightening force of the seat belt exceeds a certain limit, the force-limiting device will appropriately loosen the seat belt to maintain stable chest pressure. Therefore, automotive seat belts play a role in restraining displacement and buffering, absorbing impact energy, dissipating inertial force, and avoiding or reducing the severity of injuries to drivers and passengers. Automotive accident investigations show that in frontal collisions, wearing a seat belt can reduce fatalities by 57%, in side collisions by 44%, and in rollovers by 80%.

Does E or F indicate a full fuel tank?

In a car's fuel gauge, F stands for 'FULL', indicating the tank is full. The F on the fuel gauge is derived from the English word 'FULL', signifying a full tank, which can be translated as full or complete. E stands for 'Empty', representing low fuel. When the needle points towards the F, it means there is more fuel, and the closer it is to E, the less fuel remains. Many car fuel gauges also have a red mark near the E, indicating that the tank is almost empty and should be refueled promptly. Do not wait until the warning light comes on to refuel: This is because the fuel pump is located inside the fuel tank and relies on gasoline for cooling and lubrication. Insufficient fuel can hinder the proper operation of the fuel pump and reduce its lifespan. It is not advisable to fill the tank completely when refueling: This is because gasoline expands when heated and evaporates into gasoline vapor under high temperatures in summer, requiring space to accommodate this. If the tank is filled to the brim without any space, gasoline vapor or even liquid gasoline may enter the carbon canister for storage. Once the carbon canister is full, the excess may escape into the air, leading to both waste and environmental pollution.

Do Vehicles Need to Be Started Occasionally During Long-Term Parking?

Vehicles parked for an extended period should have their engines started occasionally, preferably once a week. There are several precautions to take when a vehicle is not driven for a long time. Clean Thoroughly: Before parking the vehicle, it should be thoroughly cleaned and tidied up, ensuring no mud stains remain. Tire pressure should be adjusted to normal levels, and all electrical circuits should be confirmed as turned off. Regular Charging: Disconnect the battery terminals. Before long-term parking, the battery should be fully charged and then disconnected. If the parking duration is very long, the battery should be periodically recharged during the parking period. Keep Dry: Parking in a garage is ideal (if not available, use a car cover) to avoid moisture corrosion from rain and to keep the vehicle dry. Seal the Fuel Tank: The gasoline tank should be tightly sealed. During long-term parking, the octane rating of gasoline decreases as light components evaporate and gum content increases, thereby reducing its anti-knock properties. Therefore, the gasoline tank must be tightly sealed, and exposure to high temperatures should be avoided. It is also advisable not to store gasoline for too long.

Is Engine Heat Normal?

Engine heating is normal. Cylinder Temperature: The temperature inside the engine cylinders during combustion can reach several hundred degrees Celsius, and the engine typically maintains this temperature range. As heat dissipates, the temperature of surrounding components will gradually rise. The car engine is one of the vital components of a vehicle, requiring regular checks on its operating condition. Precautions: When the engine coolant temperature is high, you should pull over as soon as possible and keep the engine idling. Do not turn off the engine immediately. Turn the car's heater to its maximum setting. If the engine hasn't overheated (boiled over), you can open the hood to assist with cooling. Wait until the coolant temperature returns to the normal range before shutting off the engine.
