What is the appropriate tire pressure for Audi Q5L?

The standard tire pressure for Audi Q5L is 2.4-2.5 bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2 bar in winter and reduced by 0.1 bar in summer. This data is based on the international GBT2978-2008 standard requirements. If you want to check the current tire pressure of your Audi Q5L during daily driving, you can activate the tire pressure monitoring system, and the tire pressure value will be displayed on the central LCD screen of the instrument panel. The specific method is to press the LCD adjustment button on the left combination instrument of the steering wheel to switch to the tire pressure monitoring system interface. Generally speaking, a tire pressure exceeding 2.8 bar is considered too high, while a tire pressure below 2.0 bar is too low. Hazards of excessive tire pressure: Reduced tire friction and adhesion, affecting braking performance; causing steering wheel vibration and deviation, reducing driving comfort; accelerating wear on the central tread pattern of the tire, shortening tire lifespan; increased body vibration, indirectly affecting the lifespan of other components; excessive stretching deformation of tire cords, reducing tire elasticity, and increasing the load on the vehicle during driving. Hazards of insufficient tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; causing heavy steering and deviation, which are unfavorable for driving safety; increased movement of various parts of the tire, leading to abnormal overheating due to excessive rolling; reduced functionality of cords and rubber, causing delamination or cord breakage and excessive friction with the rim, damaging the tire bead area and causing abnormal wear; multiplied friction between the tire and the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to tire blowouts. If the tire pressure monitoring indicator light comes on (a yellow symbol with an irregular circle, no stamp on top, four small spikes below, and an exclamation mark inside), there are generally three possible reasons: Abnormal tire pressure: Usually, an alarm is triggered when the pressure is below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the system will still record the previous data, causing the tire pressure monitoring indicator light to come on. Simply reset the tire pressure to resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, used to monitor tire pressure, is directly installed inside the tire and connected to the tire inflation port. If the sensor is damaged during driving, it will also cause the tire pressure fault light to come on. For sensor damage issues, only replacement with a new part is possible.
