When a yellow exclamation mark appears on the car dashboard, there are four possible scenarios: general fault, automatic transmission fault, abnormal tire pressure, and lighting fault. Below is a detailed analysis of these four situations: General Fault: A triangle with an exclamation mark indicates a malfunction in the car's general performance, components, or functions. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor failure. 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 is the automatic transmission fault warning light, indicating a transmission issue or that the transmission lubricant is below the normal range. Transmission fluid should be replaced promptly. Abnormal Tire Pressure: A horizontal line with an exclamation mark below parentheses represents the tire pressure monitoring warning light. This light turns on when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunction in one of the car's lights. Solution: Visit a 4S shop for inspection as soon as possible, or perform a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue. There is also a red exclamation mark inside a circled parenthesis, which represents a brake system warning. This mainly indicates a brake system malfunction or low brake fluid level. Immediate inspection of the brake system is required to avoid accidents.

How many kilometers does a general car need to run before changing the oil?

It depends on the type of oil used in the vehicle. Generally, motor oil is divided into three types: full synthetic, semi-synthetic, and mineral oil. Below is an introduction about them: I. Requirements for changing different types of oil: 1. Generally, full synthetic oil should be changed every 10,000 kilometers or once a year; 2. Generally, semi-synthetic oil should be changed every 7,500 kilometers or every 7-8 months; 3. Generally, mineral oil should be changed every 5,000 kilometers or every 6 months. II. About choosing motor oil: When selecting motor oil, pay attention to the following four factors: 1. The choice of oil should be based on the requirements of the engine. It is unnecessary to use overly advanced oil in engines with lower requirements, nor should lower-grade oil be used in engines with higher requirements. 2. Multi-grade oil should be selected whenever possible. Due to its savings, long lifespan, and high efficiency, multi-grade oil provides better protection for the engine. Based on the characteristics of multi-grade oil, phenomena such as premature darkening or lower oil pressure compared to ordinary oil may occur during use, which are normal. 3. Some domestic brand oils are of quite good quality and are much cheaper than similar imported products, so they can be used with confidence. There is no need to blindly pursue 'foreign oil.' 4. If the engine is in good condition and the seasonal temperature is low, it is advisable to use oil with lower viscosity to ensure smooth oil flow. In high-temperature seasons or when the engine is severely worn, using high-viscosity oil helps form an oil film and reduces engine wear.

What Causes the Steering Wheel of a New Car to Lean to the Left?

New car steering wheels are supposed to be straight, so a left-leaning steering wheel indicates a quality issue, possibly due to improper assembly during the steering wheel installation. Below are the reasons why a new car's steering wheel may lean to the left: 1. Steering gear malfunction: If the car's steering gear was not properly installed during assembly or if the central shaft of the steering gear has come loose, it can cause the steering wheel to lean. The reasons for steering gear issues are complex and require professional inspection at a repair shop or 4S store. 2. Uneven tire pressure on both sides of the car: If the tire pressure is uneven on both sides of the car, the vehicle will tend to pull toward the side with lower tire pressure. It is important to regularly check the tire pressure, which is generally recommended to be around 2.5 bar. 3. Different camber angles on both sides of the car: After replacing or repairing tires, it is essential to perform a four-wheel alignment promptly. Different camber angles on both sides can also cause the vehicle to pull to one side and may increase fuel consumption.

At what speed will the airbag deploy?

Here are the conditions for airbag deployment in a car: 1. Speed: The airbag requires a relative speed greater than 50km/h to deploy, with a deceleration of more than 40g in the opposite direction at the moment of collision. This means the relative speed must be >50km/h, and the impact force must meet this speed requirement. 2. Impact point: Different automakers have varying settings for airbag deployment conditions. The impact must occur near the sensors, typically within a 60° angle in front of the vehicle. For side airbags/curtains, the sensors are located near the doors. 3. Collision conditions: The airbag will only deploy in a collision with a rigid wall or obstacle. Hitting the sensor position with a hard object like a sledgehammer will not trigger it, as the sensor primarily responds to speed-induced impacts.

How to Adjust Rearview Mirrors for Normal Driving?

The steps for adjusting rearview mirrors are as follows: 1. After getting into the car, first adjust the seat to a comfortable position, then proceed to adjust the rearview mirrors. 2. Adjust the interior rearview mirror. The main purpose of the interior rearview mirror is to observe the situation of vehicles behind. It should be adjusted to an angle where we can see the maximum range behind us. Adjust the four corners of the interior rearview mirror so that the four corners of the rear windshield are visible—this angle provides the widest field of view. 3. Adjust the two exterior rearview mirrors. First, adjust the tilt angle of the mirrors so that the car body occupies one-fourth of the mirror. Then, adjust the elevation angle of the mirrors. For the left rearview mirror, adjust it so that the sky and ground each occupy half of the mirror, with the centerline aligned with the mirror's central line. Due to the driver's position, the right rearview mirror should be adjusted so that the sky occupies two-thirds of the mirror and the ground occupies one-third.

How Many Kilometers Can You Drive When the Fuel Light Comes On?

From the moment the fuel warning light comes on until the engine shuts off, you can typically drive 50-100 kilometers. Here are some details about it: 1. The labeled fuel tank capacity of civilian vehicles is approximately 35-75 liters. The red zone range on the fuel gauge varies by model, with some occupying 1/4 of the gauge and others less than 1/8. Generally, there is a reserve of about 3-5 liters of gasoline. 2. According to China's motor vehicle quality standards, automakers must leave at least a 5% margin when labeling fuel tank capacity, meaning the actual volume of the tank is usually 2-3 liters more. Combined with the 3-5 liters in the red zone, the actual remaining fuel in the tank is at least 5-8 liters. 3. The average fuel consumption of a car is generally 6.5-12 liters per 100 kilometers. Calculated, this means you can drive at least 50 kilometers, and even up to 100 kilometers on highways with good road conditions.

Where is the OBD port located on a BMW 5 Series?

The OBD port on a BMW 5 Series is located beneath a small cover panel near the area above the brake pedal. Detailed information about the OBD port is as follows: 1. OBD stands for On-Board Diagnostics, which translates to "vehicle diagnostic system" in Chinese. This system continuously monitors the engine's operating conditions and the working status of the exhaust after-treatment system, issuing immediate alerts when it detects any condition that might lead to excessive emissions. 2. As the communication interface for the vehicle monitoring system, the OBD port's primary function, besides reading fault codes for vehicle repairs, is to provide various operational data about the vehicle, including data not displayed on the vehicle's dashboard.
