How to Use a Bus Cond？
There are many misconceptions about using a bus cond that you may not be aware of, which can not only affect your health but also damage the vehicle. Therefore, it is necessary to understand these misconceptions before turning on the “bus air conditioning mode.” Let’s take a look at how to use a bus air conditioning system.
1. After starting the car, wait approximately 8-15 minutes for the coolant temperature to reach normal operating temperature. At this point, you can turn on the heater. (That is, when the coolant temperature reaches the middle range.)
2. Adjust the air conditioning recirculation mode to internal recirculation.
3. Switch to heater mode. Some cars display this in red, while others use a sun indicator.
4. Turn on the AC switch.
5. Adjust the air conditioning setting to a suitable level.
Precautions for Using a Bus Cond
1. Do not turn on the bus air conditioning immediately after the car has been exposed to direct sunlight.
After a car has been exposed to direct sunlight, the interior temperature will generally be very high. In this situation, do not turn on the air conditioning immediately. It is best to open the windows for ventilation first, and wait for the hot air to dissipate before getting in the car and turning on the air conditioning.
2. Turn off the air conditioning before turning off the engine.
The reason for turning off the air conditioning before turning off the engine is that this allows the temperature inside the air conditioning ducts to rise again, eliminating the temperature difference with the outside. This keeps the air conditioning system relatively dry. If the air conditioning is not turned off first, mold can easily multiply due to moisture inside the air conditioning ducts.
How to start a bus in icy and snowy weather
To start a bus in icy and snowy weather, first start the vehicle and preheat it for about 8 to 15 minutes. Then, turn on the air conditioning by pressing and holding the “auto” button. The air conditioning will turn on automatically. In winter, the air conditioning is usually set to heating, so the “AC” button should be turned off promptly. The “AC” button is the cooling switch. Turn the air conditioning control knob to the red position to switch to heating mode.
