The normal tire pressure range for an Audi Q5 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. The tire pressure monitoring system in the Audi Q5 can be viewed on the central display. This system uses ABS wheel speed sensors to compare the rotational speed differences between tires to determine if there is abnormal tire pressure, and it will immediately alert if any abnormalities are detected. The module is integrated into the ABS pump. Generally, a tire pressure exceeding 2.8 bar is considered too high, while a tire pressure below 2.0 bar is considered too low. Hazards of overinflated tires: Reduced friction and adhesion of the tires, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates wear on the central tread pattern, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; causes excessive stretching of tire cords, reducing tire elasticity and increasing the load on the vehicle during driving. Hazards of underinflated tires: Increases friction with the road surface, leading to higher fuel consumption; makes the steering wheel heavy and prone to deviation, compromising driving safety; increases movement of tire components, causing abnormal heat due to excessive rolling; reduces the functionality of cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, damaging the tire bead and causing abnormal wear; multiplies friction with 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 at the bottom, and an exclamation mark inside), there are generally three possible causes: Abnormal tire pressure. The system typically alerts 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 indicator light to illuminate. Simply resetting the tire pressure will resolve this issue. Damaged tire pressure sensor. The sensor, which monitors tire pressure, is installed inside the tire and connected to the inflation valve. If the sensor is damaged during driving, the tire pressure warning light will come on. For sensor damage, the only solution is to replace it with a new one. The appropriate tire pressure for an Audi Q5 is 2.4 to 2.5 bar. Tire pressure refers to the air pressure inside the tire and is akin to the car's blood pressure. It plays a crucial role in the vehicle's performance and power. Tire pressure is also an indicator of the car's load capacity, which depends on the tire pressure. Taking the 2018 Audi Q5 as an example, it features a five-link independent front suspension and a trapezoidal-link independent rear suspension. It is equipped with a 2.0T turbocharged engine, delivering a maximum horsepower of 230 PS, a maximum power of 169 kW, and a maximum torque of 350 Nm, paired with an 8-speed automatic transmission.
