What does it mean when the small car exclamation mark light turns yellow?

When a yellow exclamation mark appears on the car dashboard, there are four possible scenarios: general malfunction, automatic transmission failure, abnormal tire pressure, and lighting system failure. Below is a detailed analysis of these four situations: General Malfunction: A triangle with an exclamation mark inside indicates a malfunction in the car'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 necessary 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 failure warning light, indicating a transmission malfunction or transmission fluid level below the normal range. Transmission fluid should be replaced promptly. Abnormal Tire Pressure: An exclamation mark inside a horizontal line under a bracket represents the tire pressure monitoring warning light. This light turns on when the car's 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 one of the car's lights. 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. Additionally, a red exclamation mark inside a circle with a bracket represents a brake system warning, indicating either brake system failure or low brake fluid level. Immediate inspection of the brake system is required to avoid accidents.

Do you need to shift to N gear when the car has AUTOHOLD?

No, you don't need to shift to N gear when using AUTOHOLD. AUTOHOLD is equivalent to an automatic handbrake. When you press the brake, the electronic handbrake will automatically engage. Combined with the auto start-stop function, since the brake is fully pressed, both AUTOHOLD and auto start-stop work simultaneously, the engine is in a shutdown state, and there's no need to consider gear shifting. It's important to note that the purpose of using the AUTOHOLD function is for convenience, such as when waiting at a red light. There's no need to change gears in such situations. However, when parked for an extended period, you should not keep the car in D gear. How the AUTOHOLD button works: AUTOHOLD is an extension function of the ESP system, controlled by the ESP components. When the vehicle is temporarily stopped and needs to restart shortly, the parking is handled by the ESP-controlled brakes. The computer uses a series of sensors to measure the vehicle's level and wheel torque, determining the tendency of the vehicle to move and applying an appropriate braking force to keep the vehicle stationary. This braking force is just enough to prevent the vehicle from moving, ensuring that when you press the accelerator again to move forward, there won't be a severe lurch. If the temporary parking exceeds a certain time limit, the braking system switches to mechanical rear-wheel parking, replacing the previous four-wheel hydraulic braking. When the vehicle is about to move forward, the electronic system detects the pressure on the accelerator pedal and, for manual transmission models, the clutch pedal's travel to determine whether to release the brake.

What are the solutions for tire pressure monitoring system malfunctions?

Generally, it is caused by a malfunction in the tire pressure detector or receiver module, and it needs to be resolved at a 4S shop or repair shop. Below is extended information about tire pressure monitoring: 1. Working Principle: The tire pressure monitoring system uses the sensing function of ABS to compare the rotational counts of the tires. Insufficient tire pressure shortens the circumference of the tire, resulting in different rotational counts compared to other tires during driving. 2. Tire Pressure Alert: The tire pressure monitoring alerts based on the comparison of rotational speeds by wheel speed sensors. Tire pressure display can be checked with a pressure gauge. While driving, the tire pressure loss display monitors the inflation pressure of the tires. If the inflation pressure in a tire is significantly lower than in other tires, the system will alert. When the internal pressure of the tire decreases, the working radius of the wheel changes accordingly, thus altering the rotational speed of the wheel.

What are the differences between Hamilton White and Pearl White?

White car bodies give a bright, lively, and generous impression. As a neutral color, white blends well with the external environment, creating a clean and simple feeling. White has better visual recognition, improving driving safety, and is less prone to showing dirt compared to black. Here are the differences between the two: 1. Material Composition: Pearl White and standard white are two different types of car paint. Pearl White contains fluorescent powder in its paint layer, which reflects shiny particles under sunlight, whereas standard white paint does not contain fluorescent powder and remains pure white from inside out, without emitting any fluorescent effect under sunlight. 2. Paint Characteristics: Pearl White is a type of metallic paint, while standard white is a non-metallic solid color paint with no metallic luster. In terms of long-term use, standard white tends to yellow over time, while Pearl White is more prone to color mismatch during touch-ups due to the unique properties of its paint.

What is the difference between a D license and a C1 license?

The difference between a D license and a C1 license lies in the completely different types of vehicles they authorize to drive. A D license allows driving all types of three-wheeled motorcycles and two-wheeled motorcycles; a C1 license permits driving all types of small passenger vehicles, which are essentially family cars. There is no compatibility between the two. Vehicles authorized for C1 license: The scope of a C1 driver's license includes small and mini passenger vehicles, light and mini cargo vehicles, and light, small, and mini special-purpose vehicles. Small passenger vehicles must have a seating capacity of 9 or fewer people. A C1 driver's license does not authorize driving: large buses, tractor units, city buses, medium-sized buses, large trucks, regular three-wheeled motorcycles, regular two-wheeled motorcycles, mopeds, wheeled self-propelled machinery, trolleybuses, and trams. Additionally, a C1 license does not permit driving vehicles with more than 9 seats or trucks with a total length exceeding 6 meters.

How many kilometers can you drive after the fuel gauge light comes on?

After the fuel gauge light comes on, you can generally drive approximately 40-60 kilometers. Below is more information about the fuel gauge light: 1. Introduction: The fuel gauge light is one of the essential components in a car, used to monitor the remaining fuel quantity in the fuel tank. 2. Consequences: Driving until the car runs out of fuel can cause damage to the vehicle, potentially harming the fuel pump. 3. Refueling: When refueling the car, avoid filling the tank too full. In high-temperature summer environments, gasoline can evaporate into vapor, and with no extra storage space in the tank, this not only pollutes the environment but also increases the car's fuel consumption. In winter, overfilling the tank can damage the car and fill the interior with the smell of fuel, affecting human health. There is also a risk of danger if exposed to open flames. It is generally recommended to refuel when the fuel level drops to one-quarter and to fill the tank to only 80%-90% capacity.
