An SUV tire pressure of 3.0 bar is not normal. According to the international GBT2978-2008 standard, the recommended tire pressure for standard tires is 2.4-2.5 bar. A pressure of 3.0 bar exceeds the maximum recommended value, making it abnormal. 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, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overextends tire cords, reducing elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, the tire is more prone to punctures, leading to internal cracks or blowouts.

If the lag persists, you can click the reset button to exit and then try again.

How to Match the Throttle Body on a Jetta?

First, turn the key to the power-on position, but do not start the car, meaning the engine should be off. If the car is started, the throttle body cannot be matched. After waiting for about 10 seconds, quickly press the accelerator pedal all the way down. It must be pressed down rapidly and held for 15 seconds, then quickly release the pedal. Next, turn off the ignition, remove the key, and wait for about 15 seconds. Note that the waiting time must not be less than 15 seconds; otherwise, the throttle body cannot be matched.

To provide freeze protection for the engine against low-temperature environments; 2. To offer efficient heat dissipation. The method for replacing antifreeze is: 1. Open the car hood after the engine has cooled down; 2. Open the antifreeze reservoir cap; 3. Lift the vehicle and open the radiator drain plug, drain the old antifreeze, then reinstall the drain plug; 4. Lower the vehicle and pour new antifreeze into the antifreeze reservoir.

What Causes the Car Side Mirror to Fail to Auto-fold?

Car side mirrors failing to auto-fold is due to motor malfunction or a stuck limit pin. Below are specific details about the auto-folding feature of side mirrors: 1.

This enhances passability in narrow alleys or during vehicle encounters, prevents scratches and collisions, and reduces parking space occupancy. Additionally, folding the mirrors when the owner leaves helps protect the mirror surfaces. 2.
