What Does It Mean When an Exclamation Mark Lights Up on the Car?

An exclamation mark appearing on the car dashboard indicates an abnormality or malfunction in the corresponding system. There are many indicator lights on the car dashboard that feature an exclamation mark, 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 warning 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. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, engine oil pressure sensor failure, etc. It is necessary 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. 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 fluid should be replaced promptly. Brake System Fault: An exclamation mark inside a circled parenthesis. This represents a warning for the brake system, mainly indicating a brake system malfunction or low brake fluid level. The brake system should be inspected immediately to avoid accidents. Tire Pressure Anomaly: An exclamation mark with a horizontal line below a parenthesis. This represents the tire pressure monitoring warning light, which lights up when the car's tire pressure is too low. Check the car's tire pressure and restore it 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: 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. In addition, during daily vehicle use, the fault lights displayed on the 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. Reduce speed and proceed to the nearest repair point to eliminate potential safety hazards. Red indicates a very serious problem in the corresponding system. In such cases, do not continue driving. Pull over immediately and call for professional assistance to prevent unpredictable dangers to the vehicle and personal safety. It is important to note that when the car is started, all lights will illuminate for an automatic system check and will turn off after the check is completed. If a light does not turn on when the ignition is switched on, remains lit without turning off, or lights up while driving, it indicates a fault in the related system. In such cases, seek professional help promptly for inspection to eliminate safety hazards.

How to Drive an Automatic Car?

Steps to drive an automatic car: 1. The first thing after entering the car is to fasten the seat belt, and then press the left brake pedal before starting the car; 2. Insert the car key and, while keeping the brake pedal pressed, turn the key clockwise. You will hear the sound of the car engine starting; 3. Check if the car's dashboard is normal. The left gauge shows the engine speed, and the right gauge is the speedometer. Look for any warning lights on the dashboard; 4. If there are prompts such as a door not being closed properly, address them first. Also, check if the fuel gauge shows sufficient fuel. If the fuel level is too low, go to refuel; 5. Release the handbrake, keep the brake pedal pressed, shift the gear from Park (P) to Drive (D), release the brake, gently press the right accelerator pedal, slowly apply throttle to start the car, and pay attention to the surrounding traffic conditions.

Must the tire pressure be the same for all four tires?

It is not necessary for the tire pressure to be exactly the same for all four tires. Having slight differences in tire pressure between the car tires is perfectly normal. Even if all four wheels are inflated to the same pressure initially, the tire pressure values may vary slightly after some driving. As long as the tire pressure values remain within a reasonable range, it won't have a significant impact on the vehicle. Generally, a tire pressure difference of up to 0.1bar will not cause any issues. For household cars, the recommended tire pressure is typically between 2.3 and 2.5bar. However, if the tire pressure difference is too large, some car models may experience pulling to one side, especially if the front wheels have a significant pressure difference—the car may pull towards the side with lower tire pressure. If you notice your car pulling to one side while driving, it is advisable to first check the tire pressure.

What does 'media' mean in a car?

In a car, 'media' refers to the multimedia audio and video playback function, which is part of the car's entertainment features. Pressing the 'media' button will directly take you to the relevant interface to use the multimedia player. The central control multimedia system includes entertainment audio and video playback, navigation system, air conditioning control, call system, car information feedback, etc. Various settings and controls of the car can be operated through the central control screen. The car audio system consists of: 1. Audio source components, which provide front and rear CD players for different media such as radio, tapes, MP3, DVD, and TV; 2. Speaker components, including front and rear field speakers and subwoofers; 3. Cable components, including signal cables, speaker cables, and power cables.

What Does Maximum Torque Mean?

Maximum torque refers to the twisting force generated by the engine crankshaft. For vehicles with the same transmission ratio, greater torque means more power. Maximum power is the work done by torque and rotational speed per unit time. Under fixed power conditions, it has an inverse relationship with engine speed - the faster the speed, the smaller the torque, and vice versa, reflecting the vehicle's load capacity within a certain range. The engine's maximum torque is related to the design of its intake system, fuel supply system, and ignition system. The engine's power, torque, and rotational speed are interrelated, with the specific relationship being: power equals the product of conversion coefficient, torque, and rotational speed.

What is the brake warning light?

brake is the brake system warning light. The braking device generates friction between the brake pads and the drum or disc, converting the kinetic energy of the moving vehicle into heat energy during the friction process, thereby dissipating it. The brake system consists of the control system, hydraulic system, and power assist system. Most small vehicles use hydraulic braking because liquids are incompressible and can transmit force almost 100%. The basic principle of hydraulic braking is: when the driver presses the brake pedal, pressure is applied to the brake fluid in the master cylinder. The liquid transmits the pressure through the pipelines to the pistons of the brake calipers on each wheel. The pistons drive the brake calipers to clamp the brake discs, generating significant friction to slow down the vehicle.
