Example 14


Today, my car indicated low pressure in one of my tyres. I stopped by at a petrol station, connected the air pressure device, saw a low pressure reading, pressed the button for a while and … depressurised the tire almost completely.

Why? The right button is the “minus” button, the “plus” button is on the left. (Nevertheless, the pressure indicator moves according to standard, to the right if pressure increases.)
Maybe I should have attended to the warning message before pressing the button, which advises:

fill only briefly
check in between”
