What is the normal tire pressure for Jetta VS5?
1 Answers
The normal tire pressure range for Jetta VS5 is 2.4-2.5bar. Due to seasonal factors, the tire pressure can be appropriately increased by 0.2bar in winter and decreased by 0.1bar in summer. This data is based on the international GBT2978-2008 standard requirements. The tire pressure of Jetta VS5 can be checked on the central control screen. The vehicle is equipped with a tire pressure monitoring system that provides automatic alarm prompts, eliminating the need for manual operation. Generally speaking, a tire pressure exceeding 2.8bar is considered too high, while a tire pressure below 2.0bar is considered too low. Hazards of excessive tire pressure: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread pattern of the tire, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overstretches tire cords, reducing elasticity and increasing the load on the vehicle during driving. Hazards of insufficient tire pressure: Increases friction coefficient 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; Weakens cord and rubber functions, leading to delamination or cord breakage and excessive friction with the rim, damaging the bead area and causing abnormal wear; Multiplies friction between the tire and ground, rapidly increasing tire temperature, softening the tire, and drastically reducing strength. High-speed driving may result in a tire blowout. 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 reasons: Abnormal tire pressure: Typically, an alarm is triggered when the pressure is below 1.8bar or above 3.0bar. 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 promptly, the system will still record the previous data, causing the indicator light to come on. Simply reset the tire pressure to resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, installed inside the tire and connected to the tire inflation valve, monitors tire pressure. If the sensor is damaged due to impact while driving, the tire pressure warning light will illuminate. In such cases, the only solution is to replace the sensor with a new one.
