The function of the vehicle's front emblem
The core function of the vehicle's front logo is to serve as brand identity recognition and visual image communication, fulfilling both legal compliance and cultural dissemination roles.
Core Function:
Brand Identification: As the "identity card" of the vehicle, it enables the public to identify the manufacturer and vehicle model at a distance or in an instant, serving as the most direct visual symbol to distinguish different car manufacturers.
Cultural Concept Carrier: Condensing the brand's history, technical philosophy, and values (such as the Mercedes-Benz three-pointed star symbolizing the vision of land, sea, and air power, and the Audi four rings representing merger and collaboration), it conveys the corporate spirit.
Legal and Compliance Requirements: The original factory logo is the legal exterior feature for vehicle registration, and replacing or covering it may violate the "Motor Vehicle Registration Regulations" and the Traffic Safety Law.
Aesthetic and Value Symbol： It constitutes the core of the front design， enhancing the overall aesthetic appeal； some luxury vehicle logos also imply social status and consumption level indications. Additional Explanation
It is important to distinguish between "brand logo" and "legal posting sign": the former refers to the factory logo on the grille / engine hood (the subject of the above action); the latter refers to the administrative certificates such as the inspection pass mark and the compulsory insurance mark that need to be pasted on the upper right corner of the front windshield, and their positions and functions are different. Do not confuse them. "Fault of the front car sign" usually refers to the engine fault light that lights up on the dashboard (the yellow engine outline icon), indicating that the engine electronic control system has detected an abnormality. It is necessary to judge the severity based on the color and the vehicle's condition.
Core identification and response
Icon characteristics: Irregular yellow/orange engine shape (partly with "CHECK ENGINE" or "EPC" text); if it is a red oil can, thermometer or exclamation mark circle, it belongs to other system faults.
Risk level: Yellow can be cautiously driven to the repair point for a short distance; if accompanied by shaking, abnormal noise, sudden loss of power or turning red, it is necessary to immediately stop and call for rescue.
Common causes: Oxygen sensor failure, oil tank cap not tightened, ignition coil fault, three-way catalytic converter blockage, poor fuel quality or interruption of sensor signal.
Processing steps:
Observe if it goes out after self-check (it lights up for a few seconds at the start of the engine is normal);
If it is constantly on, check if the oil tank cap is tightened and if there is obvious shaking / oil leakage;
If there are no serious abnormalities, drive at a low speed to the repair shop to read the OBD fault code;
When accompanied by high temperature, smoke or severe shaking, immediately shut off the engine, and contact a tow truck.
Note to distinguish other "front" related warnings
If you are referring to the external sign light of the vehicle head (such as abnormal light of the brand logo) or the airbag light (with a person in front of a circle / airbag icon), it is not an engine fault:
The airbag light is constantly on: It indicates a fault in the airbag system (line, sensor or torsion spring problem), and it may not pop out during a collision, so it needs to be repaired as soon as possible.
External Logo light failure: It usually does not affect driving safety, and is mostly due to bulb / LED damage or poor contact of the circuit, and can be replaced at a later date.
It is recommended to take a photo of the illuminated dashboard and compare it with the vehicle manual to confirm the specific icon, or go directly to the repair shop to use a diagnostic instrument to read the fault code for precise positioning.
