Which is high temperature, hi or lo?

[LincolnAnn]

The Hi button represents high temperature, while the Lo button represents low temperature. Hi and Lo are commonly found on many buttons. When using car seat heating buttons, please note the following: The seat heating function only works when the ignition switch is turned on. To protect the heating elements of the seat heater, avoid kneeling on the seat or applying point loads to the seat surface and backrest. If the vehicle voltage drops, the seat heating will automatically turn off to ensure sufficient power supply for the engine control system. Always turn off the seat heater after parking to prevent excessive electrical load during the next startup. Avoid adding overly thick seat cushions on heated seats to prevent abnormal overheating, which may lead to malfunctions. When using the car air conditioner, Hi means maximum fan speed, while Lo means minimum fan speed. The following precautions should also be observed when using the car air conditioner: Turn off the air conditioner during startup and rapid acceleration. Since the air conditioner switch (non-independent) consumes some engine power, it is best to turn off the A/C switch when starting the vehicle and accelerating quickly, then turn it back on after the vehicle is in motion. This prevents insufficient engine power during acceleration and startup while saving fuel. Do not set the temperature too low. In summer, setting the temperature too low can create a large temperature difference between the inside and outside of the car, easily causing the driver to catch a cold. Excessively low temperatures may also increase the risk of arthritis for passengers. Normally, the temperature inside the car should be 5°C to 6°C different from the outside temperature. Control the direction of the air vents. Based on the principle that cold air sinks and warm air rises, adjust the air vents upward when the air conditioner is on and downward when the heater is on. Do not turn on the air conditioner immediately after exposure to sunlight. After the car has been exposed to sunlight, the interior temperature is usually very high. In such cases, do not turn on the air conditioner immediately. Instead, open the windows for ventilation first, then turn on the air conditioner after the hot air has dissipated. Turn off the air conditioner before turning off the engine. The reason for turning off the air conditioner first is to raise the temperature inside the air conditioning pipes, eliminating the temperature difference with the outside. This helps keep the air conditioning system relatively dry. If the air conditioner is not turned off first, humidity can cause mold to grow in the air conditioning ducts. Additionally, starting the engine with the air conditioner still pressurized the next day can damage the engine. Therefore, always turn off the air conditioner before reaching your destination.
