How to reset the Porsche 7 18 tire pressure lamp (Porsche 7 18 tire pressure lamp reset)

First, make sure the key is turned on in the second gear, and the meter displays the kilometer interface through the menu key on the left side of the steering wheel. At this time, press the up button on the left side of the steering wheel, and the dashboard will display (rrf active:R).

Air pressure is the fate of tires. Too high or too low will shorten the service life of tires. If the air pressure is too low, the tire carcass deformation will increase, and the sidewall will be prone to cracks and warpage, which will lead to excessive heat generation, promote rubber aging, tire cord fatigue and cord breakage, increase tire contact area and accelerate tire shoulder wear. If the air pressure is too high, the tire cord will be excessively stretched and deformed, the elasticity of the tire carcass will be reduced, and the load of the automobile will be increased. If hit, internal rupture and explosion will occur. At the same time, too high air pressure will wear the crown and reduce the rolling resistance.
