hi is the abbreviation of high, hi means to adjust the air conditioning temperature to the highest, which is to turn on the warmest setting of the heater. The automobile air conditioning device and daily usage instructions are as follows: Automobile air conditioning device: Abbreviated as car air conditioning; used to adjust and control the temperature, humidity, air cleanliness, and air flow in the car compartment to the optimal state; provides a comfortable riding environment for passengers, reducing travel fatigue; creates good working conditions for the driver, playing an important role in ensuring safe driving; generally includes cooling devices, heating devices, and ventilation devices; this combined device makes full use of the limited space inside the car, has a simple structure, and is easy to operate, making it a popular modern car air conditioning system internationally. Daily use of air conditioning: Choose the appropriate air conditioning temperature; in summer, many people like to set the temperature very low, not realizing that setting the temperature too low can affect health, so the air conditioning temperature must be set appropriately; the most comfortable temperature for the human body is between 20 and 25 degrees, above 28 degrees, people will feel stuffy; below 14 degrees, people will feel cold; therefore, the air conditioning should control the car temperature between 18 and 25 degrees, too low a temperature can easily make people sick.
I've been driving for many years, and the HI indicator on the car refers to the high beam, which is the particularly bright lighting mode. It's typically used on dark or rural roads as it can illuminate farther distances, helping to spot obstacles ahead. However, always remember to switch back to low beam (LO) when encountering oncoming traffic or driving on city streets, otherwise it can dazzle other drivers and create safety hazards. During regular maintenance, check the light switch and bulb condition – older lamp sockets are prone to oxidation leading to poor contact, so timely cleaning can prevent malfunctions. Safety comes first when driving, and proper use of high beams can significantly improve nighttime visibility.
