What is the fault function of automatic start-stop system displayed on Audi a3 instrument panel?

Most of them will prompt when the battery power is low, manually turn off the automatic start-stop function, turn off the air conditioner, electric heating, lights and so on. , and press the screen to start charging for a while. After that, restart the automatic start and stop. If it doesn't work, drive to the 4s shop for inspection. Pay attention to the start-stop function, close the temporary parking and step on the brake.

Automatic start-stop is a system that can automatically control engine flameout and ignition. In the case of short-term parking, the engine automatically "sleeps", which is mainly suitable for waiting for traffic lights or traffic jams in urban traffic. After the engine is turned off, the power supply can also replace the pulley to provide working power for the engine cooling fan and the air conditioner in the car. In order to achieve the purpose of saving fuel and reducing emissions.

But such a good function also has disadvantages.

1, avoid using the start-stop system in the case of ramp.

When parking temporarily on the ramp, you should avoid opening the parking system as much as possible. The start-stop system is slow to start, the vehicle is easy to slip when the brakes are released, the engine has no time to light the fire, and the braking force is insufficient, which leads to danger.

2. Stop and go and turn off the start-stop system irregularly.

Originally, traffic jams were troublesome, and the frustration of stop-and-go was even more troublesome. It is more important to turn off the starting system to improve ride comfort than to reduce fuel consumption. Meanwhile, stop and start again. Obviously, the startup speed was different, and then ... it was plugged in again.

3. Try not to turn on the start-stop system when turning on the air conditioner.

The purpose of installing air conditioner on vehicles is to improve the ride comfort, but when the engine of most vehicles with start-stop system is turned off, the air conditioner will only supply air without cooling (heating by the temperature of the vehicle water tank), which greatly affects the ride comfort. At the same time, if the temperature inside the car is detected to be too different from the set value, the engine will start automatically. Frequent starting vibration greatly reduces the ride comfort.

4, wading, start-stop system must be closed, must be closed, must be closed, important things said three times.

Remember to turn off the start-stop system when passing through the stagnant water section. If it is necessary to stop while driving and the engine stops, the exhaust pressure will suddenly drop. Water can easily flow back to the engine from the exhaust pipe, which makes the engine unable to start.
