How to Reset the Tire Pressure on a Porsche Cayenne?
1 Answers
Ensure all tire pressures are normal, turn the ignition to the ON position, press and hold the MENU button on the combination switch, select TypePress - press the Ok button - select Setting and press the Ok button - choose Tyres and press the Ok button - select SpareWheel, press the Ok button - choose SealingSet and confirm; start the engine to let it run, at which point the dashboard will prompt whether to set the tire pressure values, select the YES option. Tire pressure warnings are very dangerous signals and require high attention. This is because tires are the primary condition for vehicle safety. Tire pressure monitoring utilizes the principle of gravitational balance. If the tire pressure is balanced, it will display as normal. If a tire is punctured and loses air, disrupting the balance of gravitational forces in the problematic tire, the monitoring system will trigger an alarm. If the tire pressure monitoring fault alarm persists: this indicates that the tire pressure is either too high or too low, and the tire pressure needs to be checked. If the tire pressure is too low, it is highly likely that the tire is leaking or damaged. When a car is driving at a constant speed on a level road, it must overcome rolling resistance from the ground and air resistance. Tire pressure significantly affects the rolling resistance coefficient. When the tire pressure decreases, the rolling resistance coefficient rapidly increases because the rolling tire deforms more, leading to increased hysteresis loss. Therefore, appropriate tire pressure ensures good vehicle performance.
