Indirect tire pressure monitoring system

The tire pressure monitoring system can detect the under-pressure of tires only during the
traveling of vehicle. If one or more tires have abnormal pressure, the indicator lamp
and tire status body diagram (If equipped with ESP) or text warning (If equipped with ABS)
are displayed on the display screen of the combination instrument.
Tip
●
The tire pressure monitoring system is developed for the match with BYD original
tires. It's recommended to use BYD original tires, otherwise there is a risk of system
malfunction warning or abnormal performance.
●
When the power switch is shifted to "OK", the system performs the functional
checking. In such case, the warning lamp and the indicator lamp turn on for a while.
Tire under-pressure
If the tire pressure is changed on one or more tires, the tire pressure monitoring system will
send a tire under-pressure warning, the indicator lamp and tire status body diagram (The
under-pressure tire turns yellow.) (If equipped with ESP) or text warning "Low tire pressure.
Please check tire pressure" (If equipped with ABS) are displayed on the display screen of
the combination instrument, and the buzzer sounds once. In such case, the driver shall
immediately park the vehicle in a safe place and check all tires and the tire pressure. While
parking the vehicle, notice the safety and avoid fierce steering/braking operations. After the
tire under-pressure warning cause is solved, reset the tire pressure monitoring system.
Warning
The different tire pressure among wheels or the tire under-pressure will probably cause
tire failure and vehicle out-of-control to result in serious casualty accident.
●
The different tire pressure among wheels or the tire under-pressure will probably
speed up the wear of tires, reduce the driving stability, and increase the braking
distance.
●
The different tire pressure among wheels or the tire under-pressure will probably
result in sudden failure or burst of tire and out-of-control of vehicle.
●
Driving the vehicle with under-pressure tire will increase the tire deflection, fiercely
increase the tire pressure, and probably result in tire burst or tire falloff from wheel.
