What sound system is equipped in the BMW 3 Series?

The BMW 3 Series uses Harman Kardon audio system. Maintenance tips for BMW 3 Series audio system are as follows: 1. Head unit: The circuit board and plastic components in the head unit are significantly affected by weather conditions. The parameters of electronic components on the circuit board vary with temperature changes. Therefore, when the car interior temperature is high, it's advisable not to turn the volume too loud, as this not only affects sound quality but also reduces the system's lifespan. 2. Mechanism: The mechanical part consists of metal and plastic components combined with circuit boards. Since metals and plastics have different specific heat capacities, they respond differently to temperature changes. When the car interior is very hot, avoid rushing when changing CD discs - let the mechanism operate automatically without applying force. For multi-disc changers, don't repeatedly press the disc change button; allow the system to control the operation automatically.

Why Does the Car Engine Overheat?

There are many reasons for a car engine overheating, most of which are caused by water pipe leakage or insufficient coolant. Common causes include: fan belt breakage, radiator or water pipe leakage, thermostat failure, and engine oil leakage. If the engine loses power while driving or produces severe knocking or piston slapping sounds, it is mostly due to engine overheating. Solutions for car engine overheating: 1. Touch the upper and lower water pipes to determine the fault by their temperature difference. If there is a significant temperature difference between the two pipes, it can be concluded that the thermostat is not working. If a replacement part is not immediately available, the thermostat can be temporarily removed as an emergency measure, but it must be replaced as soon as possible. 2. When the car engine is overheating, do not turn off the engine immediately. At this time, the pistons, cylinders, and crankshaft are in a state of high-temperature expansion. Turning off the engine may cause soft metal to peel off, and in some cases, even lead to piston seizure.

What does the odometer kilometer reading mean?

Car kilometer reading refers to the driving mileage of the vehicle. Below are relevant introductions: 1. Li-recording drum vehicle: The odometer in modern cars is different, it overcomes the shortcomings of "Li-recording drum vehicles" by not only telling how many kilometers this trip has covered, but also memorizing the total kilometers traveled since leaving the factory. Thus, whether the vehicle needs major repairs, or whether the engine's proportional relationship should be scrapped, all have records to follow. 2. Working principle: The diameter of the car wheel is known, so the circumference of the wheel remains constant. From this, the number of turns the wheel makes per kilometer can be calculated, and this number also remains constant. Therefore, as long as the number of wheel turns can be automatically accumulated and then divided by the number of turns corresponding to each kilometer, the driving mileage can be obtained.

What are the standards and procedures for refunding tuition fees at driving schools?

Personally go to the driving school's registration hall to complete the withdrawal procedures, and the balance will be refunded after deducting the fees for the training hours already completed. The refund process and standards for the automobile driver's examination are as follows: 1. Failed medical examination: If the applicant fails the medical examination after registration, no fees will be charged. 2. Subject 1: For students who pass the medical examination but have not taken the Subject 1 test, a full refund will be given if no training has been attended (excluding book fees). For students who have passed the medical examination and have taken the Subject 1 test, personally go to the driving school's registration hall to complete the withdrawal procedures, and the balance will be refunded after deducting the fees for the training hours already completed. 3. Subject 2 and Subject 3: For students who request a withdrawal after attending Subject 2 or Subject 3 training, the balance will be refunded after deducting the training hours for each subject as stipulated by the pricing department.

How to Use Lights on Sharp Curves?

Use high and low beams on sharp curves. According to relevant regulations: When a motor vehicle passes through a sharp curve, slope, arch bridge, crosswalk, or an intersection without traffic lights at night, it should alternately use high and low beams to signal. When approaching sections with limited visibility such as sharp curves or the top of a slope, or when overtaking or encountering emergencies, the vehicle should slow down and sound the horn. Vehicles in the same lane should maintain a safe distance sufficient for emergency braking. Overtaking is prohibited under the following circumstances: 1. The vehicle ahead is turning left, making a U-turn, or overtaking; 2. There is a possibility of meeting an oncoming vehicle; 3. The vehicle ahead is a police car, fire truck, ambulance, or engineering rescue vehicle performing emergency tasks; 4. Sections with no overtaking conditions such as railway crossings, intersections, narrow bridges, curves, steep slopes, tunnels, crosswalks, or urban areas with heavy traffic.
