What it means
The warning indicates that outside temperatures may be low enough for ice, commonly around freezing. Amber is an informational caution, but the symbol and trigger temperature vary by manufacturer; check the owner's manual.
What the symbol looks like: A snowflake, sometimes shown with a thermometer or road surface.
Why it comes on
- The outside temperature has fallen to the vehicle's warning threshold.
- The vehicle has just been started and is reporting the current outside temperature.
- A faulty or obstructed outside-temperature sensor is giving an incorrect reading.
What to do
- Check the outside temperature display and the owner's manual for the warning's meaning.
- Reduce speed and leave extra distance if roads may be icy.
- Use gentle steering, braking, and acceleration.
- If the reading seems implausible or the warning persists in warm conditions, arrange a sensor check.
Can I keep driving?
You can usually continue driving, but treat bridges, shaded roads, and untreated surfaces as potentially icy. Avoid sudden manoeuvres and do not rely on the warning to detect every slippery patch.
Symbols and colours differ between makes and models. Your owner’s manual shows the exact lights of your car.
