Is gear shifting required in Subject 2 of the driving test?

Which direction is the bus heading?

It's heading to the left. Because you can't see the door where passengers board. Since this side has no door, and the bus door is on the right side of the bus (meaning the opposite side is the left side of the bus), the bus is heading left. It's moving to the left. Taking the forward direction as the front, passenger bus doors are generally located on the right side of the vehicle. Is this vehicle left-hand drive or right-hand drive? If it's left-hand drive (driver on the left), then it's heading left; if right-hand drive, then it's heading right. If this were Shanghai, vehicles should be driving on the right side, with doors also opening on the right side. Since this image shows no door on the vehicle, it must be heading left. The driver's position on the left makes it easier to judge and control the distance between the vehicle and oncoming traffic from the left. In terms of ergonomics, most people are right-handed. To ensure drivers can easily reach and operate gear shifts and brakes for safety and reliability, designers naturally placed the driver's seat on the right side of the vehicle. On the other hand, when cars first appeared, most car owners were wealthy individuals who employed drivers. Having the driver's seat on the right made it convenient for the driver to exit and open the door for the owner, as well as to frequently get out and remove road obstacles to prevent punctures to the pneumatic tires. Thus, early vehicles naturally adopted a right-hand drive and right-hand traffic configuration.

Can the automatic headlights remain on without turning them off after the engine is turned off?

Yes. 'Auto' refers to the automatic headlights, which generally do not require manual intervention, and there is no need to turn them off when the engine is shut down. As long as there is sufficient light while driving, the system will automatically turn them off. However, automatic headlights can be quite sensitive at times, and if the owner finds this bothersome, they can also be manually turned off. The automatic headlights will control the switching on and off of the headlights based on the sensitivity to light levels. When 'Auto' is activated, it means the automatic headlights are in the 'on' state. The principle involves using electronic components such as photoresistors as sensors to send signals to the ECU, which controls the headlights' on/off function and the high/low beams. If the light suddenly dims while driving, the headlights will automatically turn on; if the light is sufficient, they will automatically turn off without requiring manual operation. Of course, because automatic headlights can be quite sensitive, they may sometimes turn on during the day. If the owner finds this troublesome, they can manually turn them off. After the car is turned off, if some electrical appliances are not switched off, they will continue to consume the battery's power. Once the car is turned off, the alternator stops working, and the only source of power for the entire vehicle is the battery. If some electrical devices are left on for an extended period, it can lead to battery depletion, shorten the battery's lifespan, and also affect the engine's ability to start.

Why can't the Mazda3 Axela's trunk be opened with the remote key?

First, determine whether it's a remote issue or a vehicle issue There is a button next to the driver's seat that can mechanically open the trunk. If it doesn't work, it indicates a problem with the trunk lock. In this case, you can check the trunk's condition through the emergency escape channel in the rear seat. If the lock is just tangled with debris, simply loosen it yourself. If there is no obvious obstruction preventing unlocking, it is recommended to visit a repair shop for professional assistance. If the button next to the driver's seat lights up, it indicates a remote issue. Insufficient power in the remote can cause weak signals, preventing the receiver from receiving them. Simply replace the remote's battery. If the remote is damaged, it is recommended to visit a repair shop for servicing. The main factors affecting the remote control distance are as follows: 1. Transmission power Higher transmission power increases the distance but consumes more battery and can cause interference. 2. Receiver sensitivity Increasing the receiver's sensitivity extends the remote control distance but makes it more prone to interference, leading to unintended actions or loss of control. 3. Antenna Using a straight-line antenna and keeping them parallel increases the remote control distance but occupies more space. Extending and straightening the antenna during use can enhance the remote control distance. 4. Height Higher antenna placement increases the remote control distance but is limited by practical conditions.

What should I do if the engine warning light comes on in my Audi Q3?

If the engine warning light comes on, you can follow these steps: First, check if the engine is running normally. Look for issues such as shaking, black smoke, or difficulty starting. If any of these problems are present, avoid restarting the engine. Note: If the light is red, do not restart the engine under any circumstances. If the engine is running normally and the vehicle can be driven, proceed to a service station as soon as possible to diagnose the issue. A service station can easily read the fault codes using a portable diagnostic tool, allowing for targeted repairs based on the fault information. If the engine is running normally, the owner can also try gently reconnecting various wiring harness connectors, as a loose connection might be the cause. Alternatively, turning the key repeatedly to the ON position may reset the light. Generally, the engine warning light may come on due to the following seven reasons: Sensor malfunction: Sensors such as the coolant temperature sensor, crankshaft position sensor, air flow sensor, intake temperature sensor, and oxygen sensor may become damaged, have poor contact, or experience signal interruptions. When the ECU cannot accurately obtain engine data, the engine warning light will illuminate. Fuel or oil quality issues: Failure to use the fuel or oil specified by the manufacturer may cause engine wear, leading to the warning light. Poor combustion of the air-fuel mixture: This can result in engine carbon buildup or knocking, which is detected by the oxygen sensor and reported to the ECU, triggering the warning light. Issues such as faulty spark plugs, ignition coils, fuel pumps, or clogged fuel lines can cause poor combustion. Turbocharger issues: Problems with the intake boost piping or turbocharger can also trigger the engine warning light. The most common issue is a damaged turbocharger, often accompanied by symptoms like oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake issues: Blockages in the engine’s intake system can lead to the warning light. A dirty or uncleaned air filter can cause intake problems. Exhaust issues: Faults in the exhaust system, such as problems with the rear oxygen sensor, catalytic converter, exhaust camshaft, or bearings, can trigger the warning light. The catalytic converter is the most common culprit. Using leaded gasoline, lead- or silicon-based lubricant additives, physical damage to the catalytic converter, or fuel system issues can cause catalytic converter failure. Anti-theft system malfunction: If the vehicle’s electronic anti-theft system fails or the anti-theft controller is incompatible with the engine ECU, the anti-theft system may prevent the engine from operating normally, and the warning light will illuminate.

What Causes a Car Door Lock to Make Abnormal Noises on Its Own?

Abnormal noises from a car door lock can be analyzed from the following aspects: 1. Noise caused by the door seal: After prolonged use, the door seal gradually ages, causing friction between the seal and the car body, which may result in abnormal noises while driving. 2. Noise caused by the door itself: This issue arises when the door lock striker is installed too far outward, leading to a loose fit between the door and the car body. 3. Noise caused by excessively long door hinges: Over time, the hinges' friction increases significantly, resulting in abnormal noises. 4. Noise caused by the door check strap: If the door check strap is not regularly maintained, it can also cause abnormal noises.

What does vehicle registration mortgage fee mean?

When registering a vehicle that requires mortgage processing, the vehicle registration certificate needs to be mortgaged to the financing company, which incurs a mortgage fee. The vehicle registration certificate can be retrieved after the final payment is settled. Below are relevant explanations: 1. Article 58: The tax basis for fixed assets is determined as follows: For purchased fixed assets, the tax basis includes the purchase price, related taxes and fees, and other expenditures directly attributable to preparing the asset for its intended use. 2. Loan purpose: Loans using vehicles as collateral are primarily intended for automobile consumption. Banks generally do not provide vehicle mortgage loan services; such services typically require applying through specialized private credit institutions.
