Warning Lights/Indicators 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 break 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 break 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 ABS indicator and the braking system indicator come on and the electronic parking brake (EPB) is fully released, the braking force distribution system of front and rear wheels 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 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 turns on after the vehicle is started. If electronic stability control (ESC) functions properly, the light goes out in a few seconds. If ESC is faulty, this light comes on again until the 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 break 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 break 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 started.
- 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 braking at this time can render the vehicle unstable, given the malfunction of ESC system.
Driving power limit warning light
- When the level of the high-voltage battery is low and the motor power is limited, this warning light will light up, and it is recommended to contact a BYD authorized dealer or service provider immediately.

- CPD warning light*: If the CPD fault reminder lasts for five seconds and the indicator is solid on, it indicates that the CPD system fails. It is recommended to bring the vehicle to a BYD authorized dealer or service provider for inspection.
Driver attention warning light*
- Driver attention warning (DAW) system evaluates the driver’s degree of fatigue by the vehicle operation status. The driver would be alerted according to the evaluation results to ensure driving safety.
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 break 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.
