What Does the Yellow Exclamation Mark Indicate?

When a yellow exclamation mark appears on the car dashboard, it typically indicates one of four possible issues: general faults, automatic transmission failure, abnormal tire pressure, or lighting system malfunction. Below is a detailed analysis of each scenario: General Faults: A triangle with an exclamation mark inside signifies that the vehicle's general performance, components, or functions have encountered an issue. Common causes include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, or engine oil pressure sensor malfunction. It is recommended to visit a 4S shop for diagnostics to identify the root cause. Automatic Transmission Failure: A yellow gear symbol with an exclamation mark represents the automatic transmission warning light, indicating either a transmission fault or insufficient transmission fluid. Immediate replacement of transmission fluid is advised. Abnormal Tire Pressure: An exclamation mark inside a horizontal line beneath a bracket denotes the tire pressure monitoring warning light. This illuminates when the tire pressure is too low. Check and adjust the tire pressure to the recommended range. Lighting System Malfunction: A yellow bulb symbol with an exclamation mark indicates a lighting system fault. Solutions include visiting a 4S shop for inspection or performing a self-check, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the problematic component. Additionally, a red exclamation mark inside a circled bracket signifies a braking system alert, typically due to brake system failure or low brake fluid level. Immediate inspection and repair of the braking system are crucial to prevent accidents.

Where is the new car's three-guarantee card?

The new car's three-guarantee card is located inside the vehicle compartment. Below are the relevant introductions: 1. Repair Guarantee: This refers to the completely free repair service provided by the manufacturer during the "three-guarantee" validity period, except when the product cannot be used normally due to improper use or storage by the consumer. 2. Replacement Guarantee: This refers to a post-sales service method where consumers can request the seller or manufacturer to replace the product if the purchased product affects the user experience due to manufacturer reasons. 3. Return Guarantee: This refers to a post-sales service method where customers can return the purchased product under certain conditions within a certain period according to their requirements.

What causes the Peugeot 308's fan to keep running after the engine is turned off?

The reasons why the Peugeot 308's fan keeps running after the engine is turned off include the following: 1. Insufficient coolant leading to high water temperature, causing the fan to run continuously. 2. The thermostat fails to open, preventing water circulation and resulting in high water temperature. 3. The water temperature sensor is damaged. 4. The fan relay is damaged. The functions of the cooling fan are as follows: 1. It is part of the car's cooling system: The radiator in the engine's water cooling system consists of three parts: the inlet chamber, outlet chamber, main plate, and radiator core. The coolant circulates inside the radiator core, while air passes outside the radiator core. The hot coolant cools down by dissipating heat to the air, and the cold air heats up by absorbing the heat from the coolant, making the radiator a heat exchanger. 2. The radiator also serves as a water storage and heat dissipation device: The car radiator cap is equipped with an air and steam valve and has a common vent hole connected to the atmosphere. When the water temperature rises, the coolant in the car radiator expands, and the steam pressure increases, opening the steam valve to release air. When the water temperature drops, the pressure decreases, and the air valve opens, allowing outside air to enter the radiator through the common vent hole, thus maintaining constant pressure inside the radiator. 3. The radiator protects the engine from damage caused by overheating: The principle of the radiator is to use cold air to lower the temperature of the coolant from the engine. The radiator has two main components: the radiator fins, made up of small flat tubes, and the overflow tank (located at the top, bottom, or sides of the radiator fins).

What unit is used to represent engine speed?

Automobile engine speed: represented by n, with the unit r/min. Here is relevant information about engine speed: Engine speed: The level of engine speed relates to the number of work cycles per unit time or the effective power output of the engine, meaning the engine's effective power varies with different speeds. Therefore, when stating the effective power of an engine, the corresponding speed must also be specified. The effective power and its corresponding speed specified on the engine's product nameplate are referred to as the rated power and rated speed, respectively. The operating condition of the engine at rated power and rated speed is called the rated condition. Rated power is not the maximum power the engine can produce but the maximum usable limit of effective power determined based on the engine's purpose. For the same engine model, the rated power value may differ depending on its intended use. Effective torque also varies with engine conditions. Therefore, the maximum torque an automobile engine can output and its corresponding speed are used as an indicator to evaluate the engine's dynamic performance. Speed measurement: Typically, a speed sensor is used, corresponding to the signal teeth on the flywheel, to measure the engine's speed. Speed range: During idle, the engine speed generally ranges from 700-1100 r/min.

Turn off the AC before shutting down the engine or shut down directly?

Turn off the AC before shutting down the engine. Here are the relevant explanations: 1. Correct practice: For automotive design, directly shutting down the engine is not the correct practice. Just like it's best to close open programs before turning off a computer. Therefore, turning off the interior lights, wipers, music players, AC, etc. before shutting down the engine is the correct approach. 2. Mold growth: Not turning off the AC before shutting down the engine basically does no harm to the engine. However, there's another issue that cannot be ignored: In the AC ducts, the previously cooled air will remain stagnant due to the sudden cessation of air exchange, leading to the growth of a large amount of mold over time.

Where Can You Get Your Car Painted?

You can get your car painted at a 4S shop or a professional car beauty center. The reasons are as follows: 1. Professionalism: 4S shops or professional car beauty centers use very professional painting equipment. 2. Technical issues: For some hard-to-paint parts, professionals can do a better job. Information about car painting is as follows: 1. Car painting: It refers to applying a layer of paint on the car surface to protect the car. Baking paint is generally used for car painting. 2. Types of car paint include: standard paint; metallic paint; pearl paint; clear coat; matte paint.
