Before the lighting test, the engine should be started. Reasons for stalling: Automatic transmission models: Automatic transmission models are less likely to stall, whereas manual transmission models may stall frequently due to lower driving proficiency. However, it is not impossible for automatic transmission vehicles to stall, mainly due to the use of low-quality fuel causing engine carbon buildup and stalling. Precautions for stalling: For automatic transmission vehicles, stalling is primarily caused by the use of low-quality fuel. One solution is to refuel at reputable, larger gas stations with higher-grade fuel, such as 97-octane gasoline. Although it is more expensive, it ensures a longer lifespan for your vehicle and better performance while driving.

Of course, you should start the engine before the lighting test—that's a lesson I learned the hard way. When I was learning to drive, I was lazy and operated the light switches without starting the engine. The lights wouldn't turn on no matter what—turns out the battery didn’t have enough power to supply them. The lighting test checks headlights, turn signals, etc., and the vehicle needs to be running because if the engine isn’t on, it relies solely on the car battery, which drains over time, causing the lights to dim or even go out. If this happens during the test, the examiner will mark you as failing outright—how unfair would that be? So now I’ve made it a habit: start the engine first, confirm the lights are working properly, and then proceed with the checks. Don’t risk failing the test just to save a little time. Actually, this isn’t just for the test—it’s important for everyday driving too. For example, unstable lighting at night can easily lead to accidents, so beginners especially need to pay extra attention to their vehicle’s condition.

Why doesn't the air conditioning cool properly when turned on in the car?

Excessive lack of refrigerant leads to reduced cooling effectiveness. Here is relevant information: 1. Other causes: Excessive impurities in the refrigerant and refrigeration oil can cause minor blockages, resulting in insufficient cooling capacity. Insufficient refrigerant leads to inadequate cooling. A dirty condenser or a loose compressor drive belt can also cause the air conditioning to not cool properly. 2. Refrigerant: Refrigerant loss is mainly due to leaks. Damage to the air conditioning flap motor is a relatively rare issue, but it does occur. The purpose of cleaning the radiator and condenser is primarily for heat dissipation. In spring, cotton-like seeds from poplar and willow trees sticking to the condenser can cause issues such as excessively high engine temperatures or poor air conditioning performance.

What does AQS mean for Geely cars?

The APS on the car's center console stands for Accelerator Pedal Sensor. Additional information: 1. The accelerator pedal, also known as the throttle pedal, primarily controls the opening of the engine throttle valve, thereby regulating the engine's power output. Traditional accelerator pedals are connected to the throttle valve via throttle cables or linkages. 2. With the continuous advancement of automotive electronic technology, electronic throttles are becoming increasingly widespread. When a driver presses the accelerator pedal of an electronic throttle, it essentially sends a throttle pedal position sensor signal to the engine ECU. 3. The accelerator pedal mainly controls the throttle valve's opening to regulate the engine's power output. In some vehicles, the accelerator pedal is connected to the engine's throttle valve via throttle cables or linkages, and when the driver presses the accelerator pedal, it directly controls the throttle valve.

What to Do When the Turn Signal Goes Out While Pulling Over

When the turn signal goes out while pulling over, it needs to be reactivated. The reasons and methods are as follows: 1. Failure to reactivate the signal may result in penalty points: During the driving test (Subject 3), after confirming the parking spot and before preparing to park, the right turn signal must be turned on. Not activating the signal will lead to penalty points. 2. Additional tips: Use your hand to hold the signal lever in place to prevent it from resetting. During the test, when signaling, you can use two fingers to keep the lever from returning to its original position. 3. Other scenarios: Normally, when adjusting direction while pulling over, the turn signal will automatically reset when the steering wheel is straightened. If the turn signal does not turn off after steering correction, simply turn it off before shutting off the engine.

What Causes a Car Alarm to Sound?

Continuous sounding of a car alarm may be caused by a fault in the main control door grounding wire, commonly known as a door switch failure. Here is relevant information: 1. Car Anti-Theft Alarm: A car anti-theft alarm is a multifunctional product that not only serves as an anti-theft warning but also can remotely open the trunk, remotely lock/unlock doors, remotely open/close windows, remotely start the engine, and remotely lock the engine. 2. Precautions: Modern cars use the battery connected to the metal part of the car body, so the negative wire in a car is usually called the grounding wire. The grounding wire plays a crucial role in the car's electrical circuit, making the condition of the grounding wire key to the proper functioning of the car's electrical components.
