Cars with automatic headlights do not require manual control of the lights; the vehicle will automatically turn the lights on or off based on the surrounding light conditions. Automatic Low Beam: Automatic headlights simply mean the vehicle can automatically control the low beam switch according to the surrounding lighting conditions. When the automatic headlights are active, the vehicle has essentially turned on the low beams. Automatic headlights can be understood as an automated program that eliminates the need for manual operation of the low beam switch, making daily use more convenient. Automatic High Beam: The function of automatic high beams is quite similar to that of automatic headlights, as they can automatically control the high beam switch based on road lighting conditions. However, the conditions for activating automatic high beams are more stringent. Generally, automatic high beams will not turn on automatically in urban areas; they only activate on poorly lit highways or rural roads.

How to Reset the Maintenance Light on Changan CS75?

After maintenance, the maintenance light should be reset. The "SERVICE" indicator on the dashboard display is the maintenance cycle indicator. When the ignition switch is in the ON position, the "SERVICE" indicator on the display will flash, and it will disappear after starting the engine, indicating that the vehicle requires maintenance. After maintenance, the maintenance light should be reset. Below are additional details: 1. The maintenance schedule for the Changan CS75 is similar to other fuel-powered vehicles, divided into minor and major maintenance. Minor maintenance is required every 5,000 kilometers, while major maintenance is recommended around 40,000 kilometers. The transmission fluid is maintenance-free for the lifetime of the vehicle. 2. The Changan CS75 comes with a warranty of four years or 100,000 kilometers, whichever comes first. The warranty periods for different components may vary. 3. In terms of specific maintenance items, the engine oil and oil filter should be replaced during every maintenance service. The cabin air filter should be replaced every 10,000 kilometers, the engine air filter every 20,000 kilometers, the coolant every 20,000 kilometers, the spark plugs every 20,000 kilometers, and the brake fluid every 40,000 kilometers. 4. Please refer to the vehicle's maintenance manual for specific maintenance items. Of course, maintenance can be adjusted based on actual conditions to reduce vehicle operating costs.

What Lights to Turn On When Driving into a Tunnel?

When driving into a tunnel, turn on the contour lights and low-beam headlights. It is not recommended to use high-beam headlights in either one-way or two-way tunnels. Using high beams in two-way tunnels can impair the vision of oncoming drivers, while in one-way tunnels, high beams reflect off the rearview mirrors of vehicles ahead, which can hinder the driver's ability to observe the road conditions behind them and may also affect their driving mood. Before entering a tunnel, it is essential to slow down in advance, turn on the lights, and pay attention to the traffic signs at the tunnel entrance, especially speed limit indicators. Once inside the tunnel, avoid overtaking, speeding, stopping, or making U-turns. Additionally, maintain a safe following distance, as the significant difference in light levels when entering and exiting the tunnel can cause temporary visual disorientation.

Is It Necessary to Clean the Car Intake System?

Cleaning the car intake system is necessary. Generally, the intake system should be cleaned every 20,000 to 30,000 kilometers. Long-term intake obstruction can lead to high fuel consumption, clogged fuel injectors, unstable car idling, and throttle sticking. The solution is to regularly check the air filter or replace it directly, as carbon deposits in the intake system are formed by impurities in the air combined with moisture from the intake. Regular cleaning is essential. Intake tract cleaning primarily removes gum and carbon deposits generated during combustion, protects the fuel injectors, extends their service life, enhances engine power, and reduces fuel consumption.

Where is the throttle valve located in a car?

The throttle valve of a car is located between the air filter of the intake system and the engine block. The throttle valve is a controllable valve that regulates the amount of air entering the engine. After the air enters the intake manifold, it mixes with gasoline to form a combustible mixture, which then burns to generate power. It is one of the key components in the fuel injection system of an engine. Throttle valves are categorized into: 1. Traditional engine throttle valves: Their operating mechanism works via a cable or linkage rod, with one end connected to the accelerator pedal and the other to the throttle linkage plate. 2. Electronic throttle valves: These use a throttle position sensor to control the opening angle of the throttle valve based on the engine's energy requirements, thereby adjusting the amount of air intake.

What Are the Functions of an Automotive Throttle Position Sensor?

The function of an automotive throttle position sensor is to detect whether the engine is in idle condition or under load, whether it is accelerating or decelerating. Essentially, it is a variable resistor with several switches, installed on the throttle body. The throttle position sensor is also known as the throttle opening sensor. The resistor's rotating shaft is linked to the throttle and has two contacts: a full-open contact and an idle contact. When the throttle is in the idle position, the idle contact closes, sending an idle condition signal to the computer. When the throttle is in other positions, the idle contact opens, outputting voltage signals corresponding to different throttle angles. The computer then identifies the engine's load based on the signal voltage value.

What is the function of an automotive thermostat?

The function of an automotive thermostat is to automatically regulate the amount of coolant entering the radiator based on the coolant temperature, thereby adjusting the cooling system's heat dissipation capacity to ensure the engine operates within an appropriate temperature range. When the coolant temperature is below the specified value, the refined paraffin wax inside the thermostat's temperature-sensing element remains in a solid state, and the thermostat valve closes the passage between the engine and the radiator under the action of a spring, causing the coolant to return to the engine via the water pump. When the coolant temperature reaches the specified value, the paraffin wax begins to melt and gradually turns into a liquid, expanding in volume and compressing the rubber tube to make it contract. As the rubber tube contracts, it exerts an upward thrust on the push rod, allowing the coolant to flow back to the engine via the radiator and thermostat valve, and then through the water pump.
