BYD Seal Warning Light Symbols and Indicators

As a BYD Seal owner, understanding your vehicle’s dashboard indicator lights and warning symbols is paramount for safety and efficient vehicle operation. This comprehensive guide will provide an in-depth explanation of each warning light and symbol, ensuring you have a clear understanding of their meanings and what actions to take.

Let’s dive into the specifics of each warning light:


Smart Key Warning Light

Description: When the key is not detected in the vehicle upon pressing the START/STOP button, this warning light comes on briefly, accompanied by a beep and a message on the instrument cluster. If you have an electronic smart key in the vehicle, the warning light won’t activate, allowing you to power on your vehicle. If the warning light flashes after pressing the START/STOP button, it indicates low battery in the key. When the key is absent, the instrument cluster prompts to confirm its absence.


BYD Seal ABS Fault Warning Light

Description: This warning light illuminates when you turn on the ignition. If the anti-lock braking system (ABS) functions properly, it should go out within seconds. If a fault occurs, the light reactivates until the issue is resolved. It’s crucial to understand that when the ABS fault warning light is on (with the parking system fault warning light off), the braking system continues to work while the ABS does not.


Tire Pressure Fault Warning Light

Description: This light activates upon ignition and should turn off within seconds if the tire pressure monitoring system functions correctly. If it turns on again, it signifies a problem with the system. Different indications on the instrument cluster, such as “—” for tire pressure or “No Signal,” provide specific details about the issue. It’s important to act promptly, especially when values turn red or yellow, indicating rapid tire leaks or under-pressure conditions.


BYD Seal ESC Fault Warning Light

Description: This warning light comes on when you start the vehicle. If the electronic stability controller (ESC) is operational, it should extinguish within seconds. A flashing ESC warning light means the system is actively working. However, if the ESC warning light remains on, the ESC system is compromised, resulting in an extremely unstable vehicle, especially during sharp turns and obstacle avoidance.


ESC OFF Warning Light

Description: When you press the ESC OFF switch, this warning light remains steady on, deactivating the ESC system. Pressing the switch again will turn it off, reactivating the ESC system.


Driving Power Limit Warning Light

Description: This light comes on when the vehicle’s power is restricted. It’s essential to contact a BYD authorized dealer or service provider promptly in such cases.


Headlight Fault Warning Light

Description: A yellow headlight fault warning light indicates a headlight issue. It’s advisable to visit a BYD authorized dealer or service provider for inspection.


Blind Spot Detection (BSD) Indicator

Description: This indicator suggests potential issues with the blind spot detection system. Contact a BYD authorized dealer or service provider for inspection.


BYD Seal Main Alarm Indicator

Description: When this indicator activates, it’s important to check the fault prompt or warning on the instrument cluster for further details.


Driver Attention Warning Light

Description: The Driver Attention Warning (DAW) system evaluates the driver’s level of fatigue based on vehicle operation. Depending on the evaluation, it provides reminders to ensure safe driving.


CPD Indicator/Warning Light

Description: The Child Presence Detection (CPD) indicator alerts you if CPD is turned off (steady on) and suggests enabling it. The warning light (solid on) indicates CPD system failure, necessitating inspection by a BYD authorized dealer or service provider.


Seat Belt Reminder Indicator

Description: With the ignition on, this indicator activates if any front or rear seat passengers haven’t fastened their seat belts, remaining on until they do.


Airbag Fault Warning Light

Description: This light turns on briefly upon ignition and then goes out if the airbag system is functioning correctly. It monitors multiple airbag components and connections. A steady-on or reactivated warning light indicates an issue, necessitating immediate inspection.


BYD Seal Parking System Fault Warning Light

Description: When the brake fluid level is low and the braking system has a fault, this warning light activates. It’s essential to park the vehicle safely and consult a BYD authorized dealer or service provider immediately.


Steering System Fault Warning Light

Description: This warning light stays on when the steering system is faulty, suggesting a visit to a BYD authorized dealer or service provider for inspection.


BYD Seal Zero Position Indicator Light

Description: When abnormal operations, such as low-voltage battery disconnections, cause a power loss, this indicator activates upon re-establishing power. To reset it, perform a zero self-learning operation of the steering wheel angle. This involves turning the steering wheel slowly left and right and waiting for it to reset.


Low-Voltage Power System Fault Warning Light

Description: If this warning light turns on while driving, it signals a problem with the DC or low-voltage power system. Safely pull over and turn off non-essential devices before contacting a BYD authorized dealer or service provider for assistance.


BYD Seal Powertrain Fault Warning Light

Description: This light indicates a powertrain issue when activated. Avoid driving with this warning light on and contact a BYD authorized dealer or service provider for an inspection.


High-Voltage Battery Overheating Warning Light

Description: This light suggests high-voltage battery overheating. When flashing, it’s vital to stop the vehicle immediately to allow it to cool down, as overheating may result from steep inclines, stop-and-go traffic, rapid acceleration, or long, continuous driving.


High-Voltage Battery Fault Warning Light

Description: This light activates upon ignition and should extinguish after a few seconds if the high-voltage battery system functions correctly. If it remains on or reactivates during driving, it indicates a system fault requiring inspection.


BYD Seal PCW Warning Light (Red)

Description: This warning light, when on or flashing, advises maintaining a safe following distance from the vehicle ahead to prevent potential collisions.


Motor Coolant Overheating Indicator

Description: A solid indicator indicates elevated motor coolant temperature. Park the vehicle safely and wait for it to cool down.


BYD Seal TSR Indicator

Description: When this indicator is on, it signifies the vehicle system’s recognition of the current road section’s speed limit.


Intelligent Camera Unavailability

Description: This indicator appears when the intelligent camera becomes unusable. Check for obstructions or fog on the camera, and if the issue persists, contact a BYD authorized dealer or service provider.


Please Check the Gear
