What does max mean in cars?

[ChristopherAnn]

MAX in cars refers to the maximum value. Below are the meanings of MAX in different positions: Car air conditioning system MAX: MAX indicates the upper limit of the cooling mode. Engine oil dipstick MAX: MAX represents the upper limit of the fluid level. When adding engine oil, make sure the fluid level does not exceed the MAX mark. Car fluid reservoir MAX: MAX on car fluid reservoirs indicates the upper limit of the fluid level in each reservoir. The fluid level should not exceed the horizontal line corresponding to MAX and should be between the upper and lower limits.

I often get asked this question during casual driving conversations. The term 'car max' usually has two meanings: one refers to the US used car chain CarMax, which has physical stores and online platforms in multiple cities, specializing in certified used car transactions with a reputation for transparent processes and guaranteed vehicle quality. The other is the 'max' button on in-car controls, such as the air conditioning system, which when pressed, turns the fan to maximum speed for quick cooling or heating. Personally, I think the name is quite clever, conveying a sense of maximum convenience and efficiency—whether buying a car or using max controls, it’s all very hassle-free.
