Indicators/Warning Lights Description

Smart key warning light

If the key is not in the vehicle when you press the START/STOP button, this warning light comes on for a few seconds, a beep sounds, and the message “No key detected, please confirm if the key is in the vehicle” is displayed on the instrument cluster.
If you press the START/STOP button while an electronic smart key matching the model is in the vehicle, this warning light does not light up. The vehicle can now be powered on.
If the warning light flashes after you press the START/STOP button, it indicates low battery of the key.
If the key is not in the vehicle, the instrument cluster prompts “No key detected, please confirm if the key is in the vehicle”.

ABS fault warning light

This warning light comes on when the ignition is on. If the anti-lock braking system (ABS) is working properly, the light goes out in a few seconds. Thereafter, if the system fails, the light lights up again until the fault is cleared.
When the ABS fault warning light is on (with the parking system fault warning light off), the braking system continues to operate whereas the ABS does not.
When the ABS fault warning light is on (with the parking system fault warning light off), since the ABS system does not operate, the wheels will be locked in case of emergency braking or braking on a slippery road.
If any of the following cases occurs, it means there is a fault in components monitored by the warning light system. In that case, contact a BYD authorized dealer or service provider for vehicle inspection as soon as possible.
- This warning light does not come on or is steady on when the ignition is on.
- This warning light turns on during driving.

REMINDER

A warning light that lights up briefly during operation does not indicate a problem.
If the ABS fault warning light is still on while the braking system warning light is on, immediately park the vehicle in a safe place. It is recommended to contact a BYD authorized dealer or service provider. In this case, if brakes are applied, the ABS will not work and the vehicle will become extremely unstable.
If both the ABS indicator and braking system warning lights go on after the electronic parking brake (EPB) is released, it indicates that the electronic brake-force distribution (EBD) system of the front and rear tires has also failed.

Tire pressure fault warning light

This warning light comes on when the ignition is on. It turns off in a few seconds if the tire pressure monitoring system is working properly. If the system fails, this warning light turns on again.
When the tire pressure fault warning light comes on or flashes, the message “Please check TPMS” is displayed
on the instrument cluster, and the tire pressure is displayed as “—“, it indicates that the tire pressure system is faulty.
When the tire pressure value displays “No Signal”, it indicates that the tire pressure signal at this location may be interfered or the tire pressure monitoring module is damaged.
When the tire pressure fault warning light flashes rapidly and one or more values turn red on the tire pressure screen on the instrument cluster, the corresponding tire is leaking rapidly.
When the tire pressure fault warning light is solid on and one or more values turn yellow on the tire pressure screen on the instrument cluster, the corresponding tire is in under-pressure condition. When the temperature value of one or more tires turns yellow, it indicates that the tire temperature is too high.

In the event of any of the situations above, it is recommended to contact a BYD authorized dealer or service provider for inspection as soon as possible.

ESC fault warning light

This warning light comes on when the ignition is on. If electronic stability controller (ESC) functions properly, the light goes out in a few seconds. If the system fails, this warning light turns on again until the system fault is cleared.
If the ESC warning light flashes temporarily while the vehicle is in motion, it indicates the ESC system is working.
When the ESC warning light turns on (with the ABS fault warning light and the parking system fault warning light off), the ESC fails, but the ABS and the braking system continue to operate normally.
When the ESC warning light turns on (with the ABS fault warning light and the parking system fault warning light off), the ESC system does not work. This means the vehicle is extremely unstable at sharp turns or when the driver steers away from obstacles ahead.
If any of the following cases occurs, it means there is a fault in components monitored by the warning light system. In that case, contact a BYD authorized dealer or service provider for vehicle inspection as soon as possible.
This warning light remains off (self-check not performed) after the vehicle is powered on.
This warning light is steady on while driving.

REMINDER

A warning light that lights up briefly during operation does not indicate a problem.
If the ESC warning light remains on while the warning lights for the ABS and the braking system are on, immediately stop the vehicle in a safe place and contact a BYD authorized dealer or service provider. This is because braking at this time can render the vehicle extremely unstable, and the anti-lock braking system does not work at all.

ESC OFF warning light

When the ESC OFF switch is pressed, this warning light should remain steady on and the ESC system will not operate. When the ESC OFF switch is pressed again, this warning light should turn off and the ESC system resumes its normal operation.

REMINDER

While the ESC OFF warning light is on, the driver must stay alert and keep driving at a lower speed when making a sharp turn and when avoiding an obstacle which appears suddenly, because ESC system is malfunctioned at this time and braking will cause instability.

Driving power limit warning light

When the power of the vehicle is limited, this indicator will come on. In this case, contact a BYD authorized dealer or service provider in time.

Headlight fault warning light

When the warning light is yellow, it indicates the headlight is faulty, and it is recommended to bring the vehicle to a BYD authorized dealer or service provider for inspection.

Main alarm indicator

If this indicator goes on, check the fault prompt or warning on the instrument cluster.

Seat belt reminder indicator

With the ignition switched on, if any passenger on the front seats or rear seats* has not buckled up, the seat belt reminder indicator lights up. It remains on until the seat belt is fastened.

Airbag fault warning light

With the ignition switched on, this warning light turns on and then
goes off in a few seconds if the airbag system is working properly. This warning light is used to monitor the airbag ECU, collision sensors, inflation device, warning lights, connections, and power supply.
If any of the following cases occurs, it means there is a fault in components monitored by the warning light system. In that case, contact a BYD authorized dealer or service provider for vehicle inspection as soon as possible.
- When the ignition is switched on, this warning light remains off or is solid on after the ignition is switched on.
- This warning light turns on during driving.

Parking system fault warning light

When the brake fluid level is low and the braking system is faulty, this warning light lights up. If any of the following conditions occurs, immediately park the vehicle in a safe place. It is recommended to contact a BYD authorized dealer or service provider.
- This warning light comes on when the ignition is switched on and the brake fluid level is low.
  REMINDER
  - When the brake fluid level is low, park the vehicle because it is dangerous to continue driving.
This warning light is solid on although after starting the vehicle, the brake fluid level and EPB system operation are normal (the EPB is engaged and released normally, and the message “Please check the EPB” is not displayed).
- Fault warning lights for parking brake and ABS come on simultaneously.
  REMINDER
  - A warning light that lights up briefly during operation does not indicate a problem.

Steering system fault warning light

When the steering system is faulty, this warning light is steady on. It is recommended to bring the vehicle to a BYD authorized dealer or service provider for inspection.
REMINDER
- The steering system features an electric motor to reduce the force required to turn the steering wheel.
- When turning the steering wheel, a hum may be heard from the running motor.
- Do not turn the steering wheel to its limit position for more than five seconds, otherwise the temperature protection will be activated and the steering system will be damaged or steering will become heavy.
If you have turned the steering wheel frequently with the vehicle staying put for a long time, the steering wheel may become difficult to turn even if the warning light does not turn on. This is not a fault.
- To prevent steering system overheating, the power assist effect will be reduced if the steering wheel has been frequently turned with the vehicle staying put for a long time. As a result, the steering wheel become difficult to turn. In this case, reduce steering frequency or power off the vehicle. The system will recover within 10 minutes.

WARNING

If the steering system warning light goes on, immediately park the vehicle safely, and contact a BYD authorized dealer or service provider.
