TPMS full name tire pressure monitoring system，Real -time automatic monitoring of the tire by installing the launch of the sensor chip on each wheels，Timely discover abnormal tire pressure to prevent explosive accidents。

The current commonly used tire pressure monitoring system is mainly divided into two types:

Direct tire pressure monitoring system，PSB (Pressure-Sensor BASED) -TPMS

The pressure sensor fixed in each tire directly seabet iomeasures the tire pressure，Then send the data to the central receiver through the unlimited transmitter，The actual pressure value of each tire will be displayed on the instrument in the car。

Indirect tire pressure monitoring，WSB (WHEEL-Speed BASED) -TPMS

Comparison of the speed status of each tire，Identification of tire pressure、Tire damage and other abnormal conditions，and display alarm lights in the instrument。Its working principle is very simple，When the pressure of a tire is reduced，The weight of the vehicle makes the rolling radius of the wheel smaller，Because the speed of each wheel line is the same, its speed is faster than other wheels，The weight of the vehicle makes the rolling radius of the wheel smaller。

When the car leaves the factory, there will be a standard tire pressure value，Usually this value is between 2.3-2.9bar。

TIPS Tire standard air pressure can usually be found?

Tire pressure is very important for the safety of the vehicle，Daily use suggestions to use comfortable tire pressure or full -load tire pressure on tire pressure signs，Excessive or low tire pressure will have hidden safety hazards。

When the tire pressure is too high

After driving for a long time，The internal temperature of the tire rises，Gas is heated and expanded，Tire expands with it，will lead to a decrease in elasticity、The fetal wall becomes fragile，Encounter bumpy roads、External force impact，Easy to explode。

When the tire pressure is too low

Tire area increase increases，Increasing friction，will lead to rising fuel consumption; seabet appat the same time, the tire shape will increase，It will exacerbate internal steel wires、wear of the curtain layer，In severe cases, explosive tires。

There are three major reasons in daily life that may trigger tire pressure alarm:

1. Tire nailing, leakage

2. Setting tire pressure settings after replacing tires or replenishment

3. The car is placed without driving for a long time

1、Open the "Double Flash" and place a warning sign 150 meters behind the vehicle，Check the tire。

2、If there is a car -carrier gas pump or tire pressure table，can detect each tire。

On road conditions、Moving slowly under the premise of good car condition and good sight，Find the nearby maintenance station for maintenance。

You can call FAW -Volkswagen Customer Care Hotline

3、If the tire pressure is pressed within the normal range，Start the switch first，For models with tire pressure reset keys，Press the SET key for more than 2 seconds; some models can also be set through the tire pressure monitoring function on the central control screen，Settings it for resetting。

As shown in the figure below is a common screen tire pressure reset setting.
