Subject 3 straight-line driving should be maintained below 40 km/h. The test requirements for straight-line driving are that within the test driving distance, the deviation of the vehicle body from the distance to the side lines on both sides must not exceed 30 cm (meaning the vehicle body must remain almost perfectly parallel to the side lines during driving), and the steering wheel must not swing more than 5 degrees.

What are the precautions for driving on the highway for the first time?

Precautions for driving on the highway for the first time include the following: Control your speed: Highways have strict speed limits. According to national regulations, the maximum speed on highways should not exceed 120 km/h, and the minimum speed should not be lower than 60 km/h. Driving too fast increases the likelihood of traffic accidents, while driving too slow can obstruct following vehicles and reduce the efficiency of the highway. Maintain a safe distance: Ensure there is sufficient distance between your vehicle and the one in front of you in the same lane. This provides valuable reaction time in case of emergencies. At night, when visibility is lower, increase the following distance to allow more room. Stay in your lane: Always pay attention to roadside and lane markings. Do not straddle or drive on lane dividers, and avoid occupying the overtaking lane for extended periods. React in advance: When you see the brake lights of the vehicle ahead, prepare to brake immediately. When overtaking, use your turn signal in advance to alert nearby vehicles, giving them ample time to react. Avoid stopping unnecessarily: Do not stop arbitrarily while driving. If you must stop due to a malfunction, park in the emergency lane or on the right shoulder, turn on your hazard lights, and place a warning triangle 100 meters behind your vehicle. At night, also turn on your width marker lights and tail lights.

Why is there no air coming out when the air conditioner is set to heat?

Here are the specific reasons why the air conditioner does not blow air when set to heat: 1. The heating mode takes about 5-10 minutes longer than the cooling mode to start blowing air, as it hasn't reached the preheating time yet. After turning on, the air conditioner first performs defrosting before normal heating begins. 2. The four-way valve may not be open, or the valve itself could be stuck, or the electrical control may not be supplying voltage to the four-way valve. 3. The air conditioner requires refrigerant (Freon) to operate. If the refrigerant is insufficient, the unit may fail to work or temporarily stop functioning. It is necessary to call a professional to refill the refrigerant promptly. 4. The indoor pipe temperature sensor might be damaged.

How to Check if a Car is a Stock Vehicle?

Check the vehicle identification plate to determine if it's a stock vehicle. The vehicle identification plate is a label that indicates the basic characteristics of the vehicle, including the manufacturer, model, engine power, total weight, load capacity or passenger capacity, factory serial number, manufacturing date, and manufacturer name. Below are specific details about stock vehicles: 1. After a new car leaves the factory, various fluids, electronic components, batteries, rubber seals, and tires may deteriorate due to prolonged storage without periodic inspection and maintenance, leading to issues like moisture damage and aging. 2. Only a very few dealers perform periodic inspection and maintenance measures. The cost is actually not high, but it consumes manpower and time. Some 4S stores even have open-air parking lots, exposing new cars directly to intense sunlight, wind, and rain. 3. For vehicles stored for too long, without proper warehouse management, the aging of electronic components and rubber products is basically undetectable without professional testing equipment. Many vehicles stored for too long also suffer from oil and power shortages.

What are the reasons why the BMW car Bluetooth cannot be found?

Introduction to the reasons why the BMW car Bluetooth cannot be found: 1. The car's Bluetooth is not turned on: This prevents the phone's Bluetooth from detecting the car's Bluetooth within range. 2. Being too far from the car: Since Bluetooth search has a limited range, being too far away from the car will also prevent the car's Bluetooth from being detected. 3. Someone changed the car Bluetooth name: If the car Bluetooth name was altered, the originally set Bluetooth name will not appear in the search list. 4. The car Bluetooth is set to be undiscoverable by other Bluetooth devices: If the car's Bluetooth is configured not to be detected by other Bluetooth devices, it will not appear in searches.
