The reasons for a strong gasoline smell when starting the car are: 1. Insufficient air intake in the car's throttle, leading to incorrect air flow information; 2. Excessive carbon buildup in the cylinder combustion chamber and pistons, causing insufficient cylinder pressure; 3. Excessive carbon buildup inside the engine, resulting in poor atomization of the air-fuel mixture; 4. Leakage in the gasoline pipe, forming sludge at the pipe connections, with the odor entering the car through the air conditioning system. Solutions for a strong gasoline smell when starting the car include: 1. Replace the rubber hoses of the gasoline purification carbon canister; 2. Tighten or repair the gasoline pipe connections; 3. Repair or reinstall the fuel pump; 4. Avoid filling the car's fuel tank too full.

What does the exclamation mark on the Geely Emgrand GS dashboard mean?

There are five possible scenarios when an exclamation mark appears on the car dashboard: general fault, automatic transmission fault, braking system fault, abnormal tire pressure, and lighting fault. Below is a detailed analysis of these five situations: General Fault: A triangle with an exclamation mark inside indicates a general performance or component malfunction. Possible causes 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 fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a transmission issue or low transmission fluid level. Transmission fluid should be replaced promptly. Braking System Fault: An exclamation mark inside a circle with parentheses represents a braking system warning, typically indicating a braking system malfunction or low brake fluid level. Immediate inspection and repair of the braking system are 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 adjust it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunctioning light. 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 lights to identify the issue.

How to Use Hill Descent Control?

Hill Descent Control (HDC) utilizes the mechanical rotational friction of transmission gears to reduce vehicle speed when descending slopes. This system activates automatically. Below are the key features: 1. The HDC system enhances controllability on steep slopes by applying brief braking force to the front axle, complementing engine braking. 2. When any wheel loses traction, the system employs anti-lock strategies to restore traction. Each low gear in the system is preset with a target descent speed. 3. During steep descents, HDC continuously compares actual vehicle speed with the predetermined target speed, applying braking force whenever necessary to maintain the target speed.

How to use Volkswagen CleanAir?

When the car owner turns on the internal or external air circulation, the Volkswagen CleanAir function will automatically activate. Below is a detailed introduction to the CleanAir function: 1. Activated carbon air conditioning filter: The car's CleanAir is an air purification feature, typically equipped in mid-to-high-end vehicles. It adds an activated carbon layer that can adsorb more harmful substances onto the filter. 2. Negative ion air purification: Through a high-voltage circuit, plasma is generated. The protein membrane on the surface of bacteria is destroyed by positive and negative ions, causing them to lose vitality and die, thereby achieving the goal of eliminating bacteria in the air.
