What it means
This indicates a fault or unsafe condition detected in the high-voltage traction battery or its monitoring system. Red generally signals a serious problem and may require stopping; the exact colour and response vary by manufacturer.
What the symbol looks like: A battery outline with an exclamation mark or fault mark indicates a traction-battery warning; the exact symbol varies by model.
Why it comes on
- Battery cell or module fault
- Battery temperature outside the permitted range
- Fault in battery voltage or temperature monitoring
- High-voltage isolation fault
- Battery cooling system problem
What to do
- Stop in a safe place and read the vehicle's message display.
- Follow the owner's manual's instructions for this warning.
- If there is smoke, heat, a burning smell, or unusual noise, move away and call emergency services if needed.
- Arrange qualified assistance; do not touch orange cables or open the battery enclosure.
Can I keep driving?
Do not continue driving with a red traction-battery fault warning unless the owner's manual explicitly says it is safe. Avoid charging or restarting if the vehicle shows signs of heat, smoke, or damage.
Symbols and colours differ between makes and models. Your owner’s manual shows the exact lights of your car.
