What does the letter 'a' on the car dashboard mean?

When the letter 'a' appears on the car dashboard, it indicates the auto start-stop function. If the auto start-stop is turned off, the dashboard will usually display a circle with an 'a' and the letters 'off' below it. Some vehicles may show a circle with an 'a' and a slash through it. The auto start-stop function is a feature developed by manufacturers to save fuel. The engine auto start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop during driving and restarts it when it's time to move again. This is achieved by integrating an enhanced motor with idle start-stop capability into the traditional engine, allowing the engine to completely shut off when the conditions for idle stopping are met.

How to Check if a Car Compressor is Working Properly?

By observing the pressure, turn on the air conditioning, and the low-pressure side gauge should drop. If it does not drop or drops very little, the compressor can be determined to be faulty. Disconnect the compressor's low-pressure pipe, block the rear end of the high-pressure side pipe fitted with a pressure gauge, and then increase the engine speed to about 2000 RPM. At this point, the compressor's high-pressure side pressure should be around 1.5MPa, and there should be no significant change in pressure after the engine is turned off. Otherwise, the compressor can be determined to be faulty.

What Lights Should Be Used When Driving on the Highway at Night?

When driving on the highway at night, you should turn on the width indicator lights, high and low beam headlights, and turn signals. Below is a detailed introduction to the use of lights on highways: 1. Width indicator lights. When driving at night, whether on the highway or ordinary roads, the width indicator lights must be turned on. These are small lights that, when activated, illuminate the front and rear width indicator lights as well as the rear license plate light. 2. High and low beam headlights. You can use high beams when driving on the highway at night, but it's important to use them appropriately. If the distance to the vehicle ahead is large, exceeding 150 meters, you can use high beams; when the distance decreases, you should switch to low beams. When meeting another vehicle on the highway, if the central divider can completely block the light, you can keep the high beams on; but if grass, roadside trees, or metal railings cannot fully block the light, you should switch to low beams when the distance between the two vehicles is 150 meters. 3. Turn signals. Turn signals must be used when changing lanes, overtaking, entering, or exiting the highway on the highway, and you should only change lanes after ensuring it is safe to do so, to prevent vehicles behind or in adjacent lanes from reacting in time.
