The normal tire pressure for the Volkswagen Lavida is between 2.4 and 2.5 bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2 bar in winter and decreased by 0.1 bar in summer. This data complies with the international GBT2978-2008 standard. The Volkswagen Lavida's tire pressure monitoring system is displayed on the dashboard and is enabled by default. When the tire pressure is abnormal, the tire pressure warning light will illuminate to alert the driver. There is no physical button for the tire pressure monitoring system in the vehicle. 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 tire friction and adhesion, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates uneven wear on the central tread of the tire, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overstretches the tire cords, reducing 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 in various parts of the tire, causing abnormal heat due to excessive rolling; weakens the function of the 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 between the tire and the ground, rapidly raising tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in a tire blowout. If the tire pressure monitoring indicator light illuminates (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: Typically, the system will alert if the pressure is below 1.8 bar or above 3.0 bar. In this case, the tires need to be checked and the pressure adjusted. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset promptly, the system will still record the previous data, causing the tire pressure monitoring light to illuminate. Simply reset the tire pressure to resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which monitors tire pressure, is installed inside the tire and connected to the tire inflation valve. If the sensor is damaged due to impact while driving, the tire pressure warning light will illuminate. For sensor damage, the only solution is to replace it with a new component.
