Where to Adjust the Headlight Height of the Avalon?

The headlight height adjustment switch for the Avalon is located in the engine compartment. The method to adjust the headlight height of the Avalon is as follows: 1. Find a wall and park the car 10 meters away from it; 2. Measure the height from the ground to the center of the headlights and the distance between the two headlights; 3. Place horizontal masking tape on the wall at a position 0.1 meters lower than the headlights, ensuring the tape is at the exact center of the car; 4. Turn on the headlights and adjust the vertical adjustment screw until the headlight beam is centered on the tape on the wall; 5. Continue adjusting the vertical adjustment screw until the headlight beam is pointing straight ahead.

How to Buy Insurance for a New Car?

New cars require the following types of insurance: 1. Compulsory Traffic Accident Liability Insurance: It is a mandatory insurance that must be purchased for motor vehicles. The insurance company compensates for personal injury, death, and property damage caused to victims (excluding passengers in the insured vehicle) in road traffic accidents within the liability limits. Simply put, it is a 'mandatory third-party liability insurance.' This insurance cannot be dropped at will, as doing so would be illegal. 2. Third-Party Liability Insurance: Abbreviated as 'TPL,' it covers accidental incidents caused by the insured or an authorized qualified driver while using the vehicle, resulting in direct personal injury, death, or property damage to a third party. The insurance company provides compensation, and the coverage limit is chosen by the insured, typically ranging from 50,000, 100,000, 150,000, 200,000, 300,000, 500,000, to 1,000,000, mainly supplementing the shortcomings of the compulsory insurance. 3. Vehicle Damage Insurance: This insurance covers losses to the insured vehicle caused by natural disasters (excluding earthquakes) or accidents within the scope of insurance liability. The insurer compensates according to the terms of the insurance contract, which is the opposite of third-party liability insurance.

What does AQS in cars mean?

AQS (Air-Quality-System) is an air quality sensor in cars, an automatic device that can sensitively detect the turbidity and humidity of the outside air and promptly switch the car's air circulation between internal and external modes. Here is the reaction sensitivity of AQS to different pollutants: 1. Advantages of AQS: AQS is highly sensitive to vehicle exhaust. For example, during traffic congestion in urban areas, if the vehicle ahead suddenly emits a large amount of exhaust, the intelligent air conditioning system can detect it within seconds and immediately switch to internal circulation mode, ensuring the cabin air remains fresh. 2. Limitations of AQS: AQS has a moderate response to road dust. When driving on roads with light dust, AQS will not switch immediately; it only switches to internal circulation mode when the road dust becomes severe. This is why frequent cleaning of the air filter is necessary for vehicles often driven on sandy or dusty roads. AQS also reacts slowly to colorless harmful gases.

What is the horsepower of the Yuchai 4108 intercooled engine?

This engine has 140 horsepower. It is a turbocharged diesel engine, and many diesel engines utilize turbocharging technology. Turbocharging technology can increase the engine's air intake without enlarging the engine displacement. By increasing the air intake and correspondingly increasing the fuel injection, the engine's power can be enhanced. Relevant details are as follows: 1. Fuel: The engine uses a mixture of air and fuel as its power source. Increasing the air intake and then the fuel injection effectively raises the amount of fuel in the cylinders. With more fuel in the cylinders, the energy released during each combustion cycle also increases, thereby boosting the engine's power. 2. Turbocharging technology: Initially, turbocharging technology was not applied to automobile engines but was used in aircraft engines. Turbocharging technology addresses the issue of insufficient air intake that aircraft engines face at high altitudes. Later, turbocharged engines were widely adopted in both gasoline and diesel automobile engines.

What does an exclamation mark on the car dashboard indicate?

There are five possible scenarios when an exclamation mark appears on the car dashboard: general malfunction, automatic transmission failure, brake system failure, abnormal tire pressure, and lighting system failure. Below is a detailed analysis of these five situations: General malfunction: A triangle with an exclamation mark inside indicates a malfunction in the vehicle's general performance, components, or functions. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor malfunction. It is recommended to visit a 4S shop for inspection to identify the source of the problem. Automatic transmission failure: A yellow gear with an exclamation mark inside is the automatic transmission warning light, indicating a transmission malfunction or low transmission fluid level. The transmission fluid should be replaced promptly. Brake system failure: An exclamation mark inside a circle with parentheses represents a brake system warning, typically indicating a brake system malfunction or low brake fluid level. Immediate inspection of the brake system is necessary to avoid accidents. Abnormal tire pressure: An exclamation mark with a horizontal line below parentheses is the tire pressure monitoring warning light, which illuminates when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting system failure: A yellow bulb with an exclamation mark is the lighting failure indicator, signaling a malfunction in the vehicle's lighting system. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue.

How to Solve the Issue of Brake Lights Staying On After Engine Shutdown

Here are the solutions for brake lights staying on after engine shutdown: 1. Faulty brake switch causing the brake lights to stay on after shutdown. Solution: Replace the brake switch. When replacing, remove the protective panel above the brake pedal, locate the brake switch, unscrew it counterclockwise, and then install the new brake switch by screwing it clockwise. Finally, reinstall the protective panel properly. 2. Overly worn or aged brake pads causing the brake lights to stay on. Solution: Have a professional replace the brake pads. 3. Some vehicle models come with a parking warning light feature, where the brake lights stay on after shutdown to alert surrounding vehicles. In this case, no action is required.
