This is usually informational. Address it at your convenience.
What the Fog Light Indicator Means on a Hyundai Sonata
On the Hyundai Sonata, this symbol means the fog lights are active. Rear fog lights are very bright and should be turned off in clear conditions to avoid dazzling drivers behind you.
How Urgent Is the Fog Light Indicator?
How worried should you be? For the Fog Light Indicator on a Hyundai Sonata, the urgency is low. A good rule technicians rely on is 'colour plus behaviour': match the warning colour against how the car is actually performing. If the Hyundai Sonata still drives normally and the light is steady, you usually have time to plan a proper diagnosis; if performance drops or the light flashes, err on the side of caution and stop safely.
Common Symptoms Alongside the Fog Light Indicator
Alongside the Fog Light Indicator, Hyundai Sonata owners commonly report a handful of related signs. Some are obvious, others easy to miss until you pay attention. Keeping a short mental (or written) log of what the Hyundai Sonata does when the light is on gives whoever performs the repair a huge head start and can save you money on diagnostic time.

Is It Safe to Drive With the Fog Light Indicator On?
Whether it is safe to keep driving your Hyundai Sonata with the Fog Light Indicator on comes down to urgency (low) and behaviour. As a rule, if the light is red or flashing, or the Hyundai Sonata is running poorly, stop somewhere safe and arrange help rather than pushing on. If the light is amber and the car drives normally, you generally have time to reach a workshop — but 'have time' is not the same as 'ignore it', so book a check promptly.

Frequently Asked Questions
Why is the Fog Light Indicator on in my Hyundai Sonata?
Your Hyundai Sonata turned on the Fog Light Indicator after its self-diagnostics flagged an issue in that system. Because several different faults can trigger the same symbol, the smart first move is an OBD-II scan to pull the specific code before you spend any money.
Can I keep driving with the Fog Light Indicator on?
For a Hyundai Sonata, a steady amber Fog Light Indicator with normal driving generally allows a careful trip to a garage. A red or flashing light, or any change in performance, means you should stop and avoid further driving until the fault is identified.
How much does it cost to fix the Fog Light Indicator on a Hyundai Sonata?
There is no single price for the Fog Light Indicator on a Hyundai Sonata; it ranges from a no-cost adjustment to a component replacement. The honest way to control cost is to diagnose the exact code before authorising any repair, so you only pay to fix what is actually wrong.
Will the Fog Light Indicator reset itself on a Hyundai Sonata?
If the trigger was temporary, a Hyundai Sonata may turn the Fog Light Indicator off automatically after a few drive cycles. If it remains lit, the vehicle is telling you the fault is still present, and the symbol will only go out for good once the cause is fixed.
