Frost Warning (Ice Warning)
The frost warning alerts you when the outside temperature falls to about 3–4 °C or lower, when ice can form on the road.
What is Frost Warning (Ice Warning)?
It often shows a snowflake symbol and may sound a chime. Bridges, shaded stretches and exposed high ground freeze first. The sensor measures the air temperature near the front bumper, not the road surface. Many cars show the outside temperature on the dashboard so you can watch the trend.
How it works
The ambient temperature sensor reports to the instrument cluster, which shows the warning below a set threshold.
Why it matters for your car
Road surfaces can be icy even when the display shows a few degrees above zero. Slow down, increase the following distance and avoid sudden steering or braking.
