The reasons for the Epica dashboard needle jumping: dashboard damage, dead battery. The following details the reasons: Dashboard damage: If the idle speed is unstable and the needle jumps randomly when starting the car, and the throttle responds sluggishly when pressing the accelerator, it indicates dirty throttle body and intake tract; Some vehicle models have self-check function, the dashboard lights will rotate once for self-check. Sensor/speedometer cable damage or circuit failure. Dead battery: One situation is that power-consuming items were left on when the car was last turned off, such as lights or radio, causing battery drain. At this time, you can ask someone to jump-start the car, and the battery will recharge after the car starts.

What is the normal value for tire pressure?

Tire pressure is considered normal when it is between 230 to 250 kPa. Tire pressure refers to the air pressure inside the tire. Both overinflation and underinflation can shorten the tire's lifespan. Low pressure increases the deformation of the tire body, making it prone to cracks on the sidewalls, and also increases the tire's contact area with the ground, accelerating wear on the tire shoulders. High pressure, on the other hand, causes excessive stretching of the tire cords, reducing the elasticity of the tire body and increasing the load on the vehicle during driving. Tires are usually mounted on metal rims, supporting the vehicle body, cushioning external impacts, ensuring contact with the road surface, and maintaining the vehicle's driving performance.
