The appearance of an exclamation mark on the car dashboard indicates an abnormality or malfunction in the corresponding system. There are many indicator lights on the car dashboard with exclamation marks, such as the tire pressure indicator, lighting fault indicator, steering system fault indicator, brake system fault light, transmission fault indicator, and wiper fault indicator. Below is a detailed introduction to the exclamation mark fault lights: General Fault: A triangle with an exclamation mark inside. If this symbol lights up, it indicates a fault in the car's general performance, components, or functions. Main issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, engine oil pressure sensor failure, etc. It is necessary to go to a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside. This is the automatic transmission fault warning light, indicating a fault in the transmission or that the transmission lubricant is below the normal range. The transmission oil should be replaced promptly. Brake System Fault: An exclamation mark inside a circle with parentheses. This represents a warning for the brake system, mainly indicating a fault in the brake system or low brake fluid level. The brake system should be inspected immediately to avoid accidents. Tire Pressure Abnormality: An exclamation mark with a horizontal line below parentheses. This represents the tire pressure monitoring warning light, which lights up when the car's tire pressure is too low. The tire pressure should be checked and restored to the normal range. Lighting Fault: A yellow bulb with an exclamation mark. This is the lighting fault indicator, indicating a fault in one of the car lights. Solution: Go to a 4S shop for inspection as soon as possible, or check by yourself, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the problem. In addition, during daily use of the vehicle, the fault lights displayed on the vehicle dashboard are divided into two different colors, yellow and red: Yellow indicates a fault in the corresponding system, but the problem is not very serious. The vehicle should be driven at a reduced speed to the nearest repair point for maintenance to eliminate potential safety hazards in time. Red indicates a very serious problem in the corresponding system. In this case, do not continue driving. Pull over immediately and call for professional help to prevent unpredictable dangers to the vehicle and personal safety caused by forced driving. It should be noted that when the car is started, all lights will turn on, and the system will perform an automatic check. After the check is completed, the lights will turn off automatically. If a light does not turn on when the ignition is switched on, remains on without turning off, or lights up while driving, it indicates a fault in the related system. In such cases, professional help should be sought promptly for car inspection to eliminate potential safety hazards.

Is it necessary to install a main stand for motorcycles?

It is necessary to install a main stand for motorcycles. It is generally used for maintenance and repairs. Below are the relevant explanations: 1. Side stand: The direction of force is upward, or vertical, not lateral. Additionally, the tilt angle of the vehicle is limited, and the upward force required on the side is not significant. The side stand supports the side of the vehicle, and the further outward it is, the less force is needed, which is based on the lever principle. 2. Support characteristics: The main stand is stable and can lift both the front and rear wheels off the ground. However, it is less convenient to use compared to the side stand but offers greater stability. Motorcycles, driven by gasoline engines and steered by handlebars for front-wheel turning, are two or three-wheeled vehicles known for their lightweight, agility, and speed. They are widely used for patrols, passenger and cargo transport, and also serve as sports equipment.

What is the espoff button?

espoff button means turning off the Electronic Stability Program. It is a manual control switch. After pressing the espoff button, an espoff icon will appear on the dashboard, indicating that the ESP is now turned off. For all vehicles equipped with ESP, the system is enabled by default after starting the engine. The espoff button needs to be pressed only under certain specific circumstances. When the vehicle is stuck in mud or driving on sand, the speed difference between the wheels on both sides is significant. In this case, if ESP is activated, the engine torque will be continuously consumed by the wheels with less rolling resistance, and ESP will also limit the engine speed. Even if the accelerator pedal is pressed hard, it will be difficult for the vehicle to get out of trouble. At this time, turning off the ESP will make driving easier.
