System basic functions
1. Start warning
If the tires are already under low pressure status at the power-off of the vehicle, upon the
power-on of the vehicle, the system immediately alarms of the low pressure and alerts the
driver of inflating the tires before driving.
2. Low tire pressure warning
■
If the pressure in any of four tires is below the 80% of standard pressure and the
system is working, the TPMS will issue a low tire pressure warning signal and indicate
the location of low pressure tire.
■
In event of low pressure warning, please inflate the tire to standard pressure. The low
pressure warning disappears when the tire pressure is higher than 95% of standard
pressure.
3. Quick leakage warning
■ If one or more tires is leaking at a rate of ≥30kPa/min and the system is working, the
TPMS will issue a quick leakage warning signal at a high speed and indicate the
location of leaking tire.
■
In event of any leakage warning, please stop the vehicle and check the malfunctioned
tire as soon as possible. Ensure that the tire is free of malfunction before continuing
the driving.
4. Abnormal signal warning function
Under the working status, the system will issue a warning signal in event of any
malfunction.
