What does the small bulb with an exclamation mark in the middle on the car dashboard mean?

The small bulb with an exclamation mark in the middle on the car dashboard indicates a malfunction in the vehicle's lighting system. At this point, the driver should get out of the car and check which light is malfunctioning. The lighting system in a car includes turn signals, headlights, brake lights, fog lights, and width indicator lights, all of which are crucial for safe driving. If any of these lights malfunction, it can compromise safety. The most commonly malfunctioning lights are the brake lights and turn signals. When the driver presses the brake pedal, the brake lights illuminate, alerting drivers behind to maintain a safe distance and prevent rear-end collisions. Most brake light failures are caused by burnt-out bulbs, which can be resolved by replacing the bulb. When turning or changing lanes, the driver should activate the turn signals in advance to inform other drivers of their intention. If the turn signal flashes at an unusually fast rate, it indicates a malfunction, and the bulb should be replaced immediately.

What to Pay Attention to When Signing a Contract at a 4S Store for Car Purchase?

Pay close attention to all the details in the contract. Confirm the car model, color, and other information; confirm the price; confirm any gifts or perks discussed with the salesperson; confirm the payment method, whether it's full payment or financing; confirm the delivery time. When buying a car at a 4S store, pay attention to various documents: 1. Purchase invoice: The purchase invoice is the most important proof when buying a car and is also one of the necessary documents for vehicle registration. Therefore, be sure to obtain the purchase invoice from the dealer and confirm its validity. 2. Vehicle certificate of conformity: The certificate of conformity is another crucial document and is required for vehicle registration. Only cars with a certificate of conformity meet the national standards for motor vehicle quality and related requirements. 3. Warranty service card: According to relevant regulations, if a car experiences malfunctions or damages due to manufacturing defects within a certain period or mileage, the warranty service card entitles the owner to free services from the manufacturer. However, consumable parts like bulbs and rubber are not included. 4. Vehicle user manual: Users must operate the vehicle according to the instructions in the user manual. Damage caused by not following the manual's instructions will not be covered by the manufacturer's warranty. The user manual also includes key technical parameters and necessary maintenance data, serving as a reference for repairs. 5. Other documents or accessories: Some car engines come with a separate user manual, and certain optional equipment may have specific requirements or regulations. In such cases, consumers should request the relevant documents from the dealer.

What Causes the ECO Light on the Dashboard to Illuminate?

When the ECO indicator light on your car illuminates, it indicates that the vehicle's economy mode has been activated. ECO is an English abbreviation formed from the words Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The ECO mode is further divided into active ECO driving mode and passive ECO driving mode. ECO mode can be either active or passive. The difference lies in the fact that the active mode has a dedicated button, allowing the driver to choose whether to enable it. When the driver presses the ECO mode switch, the dashboard indicator light turns on, and the vehicle automatically adjusts settings such as throttle opening, transmission shift logic, and air conditioning output power. Passive ECO mode does not have a dedicated button. When the dashboard ECO indicator light illuminates, it serves only as a reminder. ECO automatically evaluates your driving behavior, and if your current driving operation achieves the optimal fuel supply, the dashboard will display the ECO indicator light accordingly. Most cars use the active ECO driving mode, which means they have a dedicated switch button. In daily driving, we can enable ECO mode, except in situations such as driving over 120 km/h, idling, being in N/P gear, or manual mode—especially when climbing hills. In these cases, enabling ECO mode would not highlight its fuel-saving characteristics and could even affect performance. Additionally, ECO mode typically deactivates under the following conditions: When the vehicle speed exceeds 120 km/h, the car prioritizes speed, and ECO mode automatically deactivates. When idling or in N/P gear or manual mode, ECO mode may also deactivate. When high torque output is required, such as when climbing a hill, the engine control unit prioritizes delivering sufficient power to drive the vehicle, and ECO mode will not operate.
