How to Open the Fuel Tank Cap on a BMW 5 Series?

What does the exclamation mark inside the brackets on the dashboard mean?

Red exclamation mark (specifically in the form of an exclamation mark inside a circled bracket) indicates a warning for the braking system, mainly due to braking system failure or low brake fluid level. Solution: Immediate inspection and repair of the braking system is required to avoid accidents. Apart from the red exclamation mark representing braking system failure, all other exclamation marks on the car are yellow, indicating general faults, automatic transmission faults, abnormal tire pressure, and lighting faults. Below is a detailed analysis of these four situations: General Fault: An exclamation mark inside a triangle indicates a fault in the car's general performance or components and functions. This could include parking sensor failure, fuel cut-off system intervention or failure, 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: An exclamation mark inside a yellow gear is the automatic transmission fault warning light, indicating a fault in the transmission or transmission lubricant below the normal range. Transmission oil should be replaced promptly. Abnormal Tire Pressure: An exclamation mark with a horizontal line below the bracket represents the tire pressure monitoring warning light. This light turns on 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 exclamation mark is the lighting fault indicator, indicating a fault in the car's lights. Solution: Visit a 4S shop as soon as possible for inspection and repair, or conduct a self-check, focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting, to identify the issue.

Is the Fuel Tank Capacity the Same as the Actual Fuel Filling Amount?

Fuel tank capacity is not the same as the actual fuel filling amount. This is intentionally set by car manufacturers to ensure the safety of normal vehicle operation. Below is relevant information about fuel tank capacity: Definition: Fuel tank capacity refers to the size of the fuel tank, measuring a vehicle's ability to hold fuel. The size of the fuel tank is directly related to the vehicle's fuel consumption. Generally, a full tank can drive over 500 kilometers. For example, a car with a fuel consumption of 10 liters per 100 kilometers usually has a fuel tank capacity of around 60 liters. Purpose: Fuel tank capacity determines the driving range. For two cars with identical engines, the one with a larger fuel tank can travel farther. To know how much fuel your vehicle's tank can hold, you can refer to two aspects: first, the fuel tank capacity specified in the vehicle's user manual, and second, actual refueling experience. The fuel tank capacity listed in the manual is smaller than the actual fuel filling amount.

Do You Need to Depress the Clutch When Shifting to Neutral?

Shifting from a gear position to neutral does not require depressing the clutch. Below is the relevant explanation: Manual Transmission: All forward gears in a manual transmission are equipped with synchronizers. When shifting gears, depressing the clutch allows the rotating drive gear to engage with a driven gear of a larger or smaller gear ratio, achieving acceleration or deceleration effects at the same rotation speed. Clutch Function: The clutch serves to disconnect the power from the drive gear. However, during vehicle movement, the driven gear still maintains rotation, requiring the synchronizer to coordinate the engagement between the drive gear and the driven gear. Once the gear shift is completed and the gears are engaged, releasing the clutch restores speed and power to the drive gear.

How to Deal with Noises from Car Windshield Wipers?

If the noise from the wiper blade is caused by the wiper blade itself, the simplest and most effective solution is to directly replace it with a new one. Generally, it is recommended to replace the wiper blade every one to two years. If the noise is due to foreign objects stuck between the wiper blade and the windshield, check and clean the wiper blade or any debris underneath it to ensure the area is clean. Solutions for other causes of noise are as follows: 1. Noise from the wiper linkage bushing: Over time, the wiper linkage mechanism may age, the wiper arm spring may lose elasticity, and the bushing may wear out or even fall off. Please inspect the wiper arm or linkage bushing. 2. Noise from the wiper motor: If the wiper motor itself is making noise, it may be a sign that the motor is nearing the end of its lifespan. It is recommended to have it checked in detail at a professional repair shop. 3. A squeaking noise when the wiper moves across the windshield is often due to incorrect wiper arm angle, causing the blade to jump on the windshield. If the wiper blade is normal, adjust the wiper arm angle so that the blade is perpendicular to the windshield. You can use pliers to adjust it—place a cloth under the wiper arm head, grip it with pliers, and bend it slightly to ensure the blade is perpendicular to the windshield. 4. Deformation of the linkage mechanism or issues with the motor or interval relay (e.g., operating too fast, too slow, or continuously) may also cause noise. Additionally, prolonged use may lead to deformation, jamming, rust, or abnormal movement of the mechanism. If you have just replaced the wiper blade, check if there is dirt or oil residue on the windshield. Clean the windshield with a cleaning solution or try another new set. If the noise persists, adjust the wiper arm angle with pliers. However, it is best to have it adjusted with professional tools at a repair shop.

Is the Subject 1 Test Required for Adding a Motorcycle License?

Adding a motorcycle license requires taking the Subject 1 test. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses": Applicants for a motor vehicle driver's license must meet the following requirements: To apply for a license for low-speed trucks, three-wheeled vehicles, ordinary three-wheeled motorcycles, ordinary two-wheeled motorcycles, or wheeled self-propelled machinery, the applicant must be at least 18 years old and under 60 years old. For those who already hold a motor vehicle driver's license: To apply for an additional license category, there must be no record of accumulating 12 penalty points in the current scoring cycle and the most recent scoring cycle before the application. The motor vehicle driver's test consists of: the road traffic safety laws, regulations, and related knowledge test (referred to as "Subject 1"), the field driving skills test (referred to as "Subject 2"), and the road driving skills and safe civilized driving common sense test (referred to as "Subject 3").

Which light to use when turning at a signalized intersection?

When turning at a signalized intersection, activate the left or right turn signal as appropriate. Below is an introduction to turn signal knowledge: Introduction: Turn signals are important indicator lights that are activated when a motor vehicle turns to alert surrounding vehicles and pedestrians. The turn signal bulb uses a xenon tube, controlled by a single-chip microcomputer circuit, with alternating left-right flashing in continuous operation. The turn signal employs a flasher unit to achieve light blinking, which can be mainly categorized into three types: resistance wire type, capacitor type, and electronic type. Structural Principle: The resistance wire type can be further divided into thermal filament type (electrothermal) and vane type (spring-loaded), while the electronic type can be subdivided into hybrid type (with contact-type relays and electronic components) and fully electronic type (relay-free). For example, the spring-loaded flasher operates on the principle of current thermal effect, using thermal expansion and contraction as the driving force to create sudden movements in the spring blade, thereby connecting and disconnecting contacts to achieve light blinking.
