When driving at night, you should turn on the width lights as well as the headlights. The functions of width lights and precautions for using lights at night are as follows: Features and functions of width lights: Width lights serve as indicator lights to alert other vehicles. These lights are usually installed along the edges of the car's roof, indicating both the height and width of the vehicle. Precautions for using lights at night: On well-lit urban roads, low beams are generally sufficient. On poorly lit roads, switch to high beams, but remember to switch back to low beams when approaching oncoming traffic. If your vehicle becomes immobile due to a breakdown or accident at night, turn on the hazard lights.

Honestly, you must turn on the width lights when driving at night! Last year, I was fined 200 yuan for forgetting to turn them on while driving at night. These small lights not only help other drivers see the width of your car but also help identify your position in rain or fog. Especially on highways, some experienced drivers get caught by patrol traffic police and lose 3 points for sleeping with their width lights on. Remember to turn the switch to the width light position as soon as you get in the car; just make sure the tail lights and license plate lights are on—don’t confuse them with the headlights. If you notice only one side is lit, it’s likely a burnt bulb or a loose plug, so get it fixed ASAP.

Parking lights are an absolute necessity for nighttime driving. My neighbor was rear-ended last week after dark because he didn't turn on his lights, and the traffic police held him fully responsible. Regulations clearly require parking lights to be turned on from sunset to sunrise, and they must also be used during daytime in rainy or foggy conditions. These small lights consume very little electricity, using only 0.1 kWh after 10 hours of operation, which is much more economical than running the air conditioning. It's advisable to develop the habit of turning the switch to the parking light position as soon as you start the car, which will illuminate the red rear parking lights and license plate lights. If your car has an automatic headlight feature, setting the knob to the AUTO position will make things even more convenient.

Why is there no horn sound when locking the old Mazda6?

There are several reasons why the old Mazda6 does not produce a horn sound when locking: Contact Erosion: Prolonged pressing of the horn can cause the horn contacts to erode, creating impedance. This reduces the current flowing through the electromagnetic coil, weakening the electromagnetic force. As a result, the armature cannot properly drive the diaphragm to vibrate, leading to a hoarse sound or even no sound at all. However, when the horn is pressed intermittently, a strong instantaneous current can still pass through the impedance, causing the horn to work sporadically. Poor Sealing Leading to Moisture: Although the interior of the horn is sealed, if the sealing is not tight, moisture can enter during car washing or water vapor may accumulate inside. This moisture can cause the contacts to become damp, preventing the horn from functioning properly.

How to Identify Good and Bad Gasoline?

Methods to identify the quality of gasoline: 1. Generally, inferior gasoline has an abnormal color, while high-quality gasoline appears clear and transparent, slightly yellow or colorless; 2. Inferior gasoline has a pungent and unpleasant smell, and the exhaust emitted by the vehicle may also have an odor; 3. Cars frequently using inferior gasoline may produce abnormal noises when starting. Gasoline is a volatile, flammable liquid hydrocarbon mixture distilled or cracked from petroleum, primarily used as fuel for spark-ignited internal combustion engines. It mainly consists of organic compounds obtained from crude oil distillation and various additives. The gasoline used in internal combustion engines has a significant impact on the local environment and is also a factor in global human carbon dioxide emissions.

Where is the hazard light switch located in a car?

The hazard light switch is an independent red triangle button. Pressing it once turns on the hazard lights. Commonly, the hazard light switch is located on the center console to the right of the steering wheel, though some models may have it positioned below the center console. Hazard lights should typically be activated in the following situations: 1. Temporary parking: Temporary parking is a frequent activity for many drivers but is also where safety is most often overlooked. In reality, many drivers simply park by the roadside without turning on the hazard lights or placing a warning triangle. This is highly dangerous as it makes it difficult for other vehicles to notice the parked car promptly. Always remember to activate the hazard lights when temporarily parked. 2. Vehicle breakdown or traffic accident: When a vehicle breaks down or is involved in an accident, it often stops in the middle of the road or moves slowly. Failing to turn on the hazard lights promptly can prevent approaching vehicles from assessing the situation ahead, especially in congested traffic, potentially leading to chain-reaction accidents. Additionally, in such cases, besides activating the hazard lights, drivers should place a reflective triangle about 200 meters behind the vehicle to warn oncoming traffic and avoid rear-end collisions. 3. Towing a malfunctioning vehicle: Towing vehicles move slowly, and if following drivers cannot discern that the vehicle ahead is being towed, they might assume it is moving normally. This could result in prolonged trailing behind, unaware that the road ahead is actually clear, causing traffic congestion or even rear-end collisions. 4. When part of a convoy permitted by traffic authorities: The most common examples are wedding convoys or car club activities. However, routinely using hazard lights in such situations is incorrect and not permitted by traffic authorities. Hazard lights should only be used in convoys specifically authorized by traffic authorities.

How often should the transmission fluid be changed for an Audi A3?

Audi A3 transmission fluid is generally replaced every 50,000 to 80,000 kilometers. The replacement interval for transmission fluid follows the same calculation method as the vehicle's maintenance cycle, based on either mileage or time. If the vehicle's manual specifies both criteria, the one that comes first should be followed. Symptoms of deteriorated transmission fluid: Slipping: During the process of gradually increasing engine speed, the rise in torque can cause gear slippage. Oil leakage: This leads to insufficient lubrication inside the transmission, making it harder for the vehicle to accelerate. Jerking: This may be caused by dirty transmission fluid, resulting in intermittent lubrication. Abnormal noises: This indicates the presence of excessive debris and impurities in the transmission fluid. Overheating: Typically, the dashboard will display a transmission overheating warning at this point. Stalling: This may occur if the input shaft speed sensor is damaged.
