What to Do If the Vehicle Fails OBD Inspection?

The solutions for a vehicle failing OBD inspection are: 1. Take the vehicle to a 4S repair shop to diagnose and clear the fault codes; 2. Visit a 4S shop to upgrade the vehicle system before reattempting the inspection. Annual inspection items include: 1. Checking whether the vehicle has been modified, altered, or reconstructed, and verifying if the driving license, license plate, and vehicle records match the actual condition; 2. Testing whether the vehicle's braking performance, lighting, exhaust, and other safety features comply with relevant regulations. Situations where a vehicle cannot participate in the inspection include: 1. Discrepancies between the vehicle condition and the driving license or recorded files; 2. Damaged or incomplete license plates or driving licenses, illegible handwriting, or self-made license plates; 3. Vehicles with modifications, alterations, or technical transformations that have not undergone approval and change procedures; 4. Vehicles that have not been marked with the required unit name and enlarged license plate characters.

Is It Harmful for an Automatic Transmission Car to Roll Forward in Reverse Gear?

Yes. It can cause impact to the chassis and driving system, with the most common issue being direct damage to the gears. In severe cases, the transmission may even be rendered unusable. Below are some parking precautions: 1. Basic parking principle: Consider both your own convenience for entry and exit as well as that of others, and also take into account potential unexpected situations. 2. Use turn signals when temporarily parking by the roadside: Always turn on the turn signal in advance when temporarily parking by the roadside, and check the rearview mirror to ensure there are no vehicles or pedestrians before pulling over. The parking location must be legally permissible and should not obstruct the passage of other vehicles or pedestrians. When parking due to traffic congestion or waiting at a traffic light, leave at least half a car length distance to prevent being trapped in the middle if the car in front breaks down. 3. Park in well-lit areas: Choose spacious and bright locations for temporary parking, and avoid hiding in corners. For long-term or overnight parking, always use a parking lot. Additionally, exercise extra caution and care when parking during severe weather conditions or on particularly crowded streets.

Where is the Car Audio Fuse Located?

The car audio fuse is located in the fuse box, and for most vehicles, the audio fuse box is situated in the engine compartment. Below is information about the components of car audio: 1. Head Unit: The head unit is the most crucial component in car audio, akin to the human brain, as it controls the type of sound produced. Currently, there are mainly two types in car audio: cassette players and disc players. 2. Speakers: Speakers play a decisive role in the entire audio system, influencing its overall characteristics. High-quality speakers have their own distinct features. In car audio system modifications, replacing speakers and the head unit is the most basic and common upgrade. 3. Amplifier: The amplifier, also known as a signal amplifier, primarily functions to amplify the power of audio signals. Typically, the head unit comes with a built-in power amplifier, but its amplification capacity is limited, making it insufficient for higher-level music demands and incomparable to external power amplifiers. Additionally, subwoofers must be directly driven by an independent power amplifier.

Reasons for Being Too Far Back in Parallel Parking

The reason for being too far back in parallel parking is either starting to park too early or being too far from the line when stopping. You can drive slightly forward a bit more before stopping, keeping the car body a little closer to the parking line. When parking, it's easier to back into the spot if you position the car slightly to the right, but be sure to also pay attention to the distance both in front and behind. Additional Information: 1. Exam Rules: For students who have completed their C1 driver's license, the length of the parallel parking space is 1.5 times the vehicle length plus 1 meter. Drive the vehicle to a position parallel to the garage in the forward direction, then reverse into the garage to the right rear without any pauses. As long as the parallel parking is within this range and does not cross the boundary lines of the parking space, it is considered a pass. 2. Parallel Parking: Parallel parking is a part of the second subject in the driver's license test. Parallel parking is becoming increasingly common in urban areas, especially as parking spaces in formal parking lots become more scarce. Many places have designated parking spaces along the sides of existing streets, creating "parallel parking spaces."

How often should the spark plugs be replaced for the Sagitar 1.4T?

The replacement interval for the Sagitar 1.4T spark plugs mainly depends on the mileage. It is recommended to replace the spark plugs once every 40,000 to 60,000 kilometers. Spark plugs are a crucial component of the gasoline engine's ignition system. They introduce high-voltage electricity into the combustion chamber and generate sparks by jumping across the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. Steps to replace the spark plugs: Open the hood, lift the plastic cover of the engine, and remove the high-voltage ignition wires. Mark the position of each cylinder to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris like leaves or dust and ensure they are thoroughly cleaned. Place the new spark plugs into the spark plug holes, hand-tighten them a few turns, and then use the socket to tighten them further. Reinstall the removed high-voltage ignition wires in the correct firing order and secure the cover.

How Long Can the Internal Circulation Be Kept On?

Do not keep the internal circulation on for too long. The internal circulation mode closes the airflow channels between the inside and outside of the vehicle. Without the fan, there is no airflow circulation, and when the fan is on, the airflow drawn in comes only from inside the car, creating an internal airflow cycle. The purpose is to prevent harmful external substances from entering the vehicle and to maintain warmth. However, prolonged use can cause a feeling of stuffiness. Additional Information: Usage of Internal and External Circulation: 1. External Circulation: If driving at high speeds for a long time without ventilation, the air inside the car becomes stale. In summer, you can open the windows for ventilation, but in autumn, opening windows at high speeds can be very cold. In such cases, turn on the external circulation to ensure timely air exchange, maintaining warmth while keeping the air fresh. 2. Internal Circulation: It can block external air, but prolonged use during long drives can lead to oxygen deprivation inside the car, especially when there are many passengers. Oxygen deprivation can cause dizziness and reduced concentration for the driver. Therefore, if the temperature inside the car is comfortable, it is recommended to turn off the internal circulation and switch to external circulation to allow fresh air into the vehicle.
