What the Fog Light Indicator Means on a Volvo S90
On the Volvo S90, 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?
In terms of priority, treat this as a low concern on your Volvo S90. The single most useful thing you can observe is whether the Fog Light Indicator is steady or blinking: a steady light generally allows a careful drive to a safe location or a workshop, whereas a flashing light signals an active fault that can cause damage if you continue. Pay attention to changes in how the Volvo S90 drives, sounds, or smells, since those symptoms sharpen the diagnosis considerably.

Frequently Asked Questions
Why is the Fog Light Indicator on in my Volvo S90?
On a Volvo S90, the Fog Light Indicator comes on because a monitored value crossed a threshold the car considers abnormal. It could be a simple, inexpensive cause or a genuine fault — the only way to be sure is to scan the vehicle and interpret the codes rather than guess from the symbol alone.
Can I keep driving with the Fog Light Indicator on?
It depends on the urgency (low) and how your Volvo S90 is behaving. If the light is red or flashing, or the car drives differently, stop safely and get help. If it is amber and everything feels normal, you can usually drive to a workshop soon — just do not put off the diagnosis.
How much does it cost to fix the Fog Light Indicator on a Volvo S90?
Repair cost for the Fog Light Indicator on your Volvo S90 depends entirely on the root cause. Because the same symbol covers cheap and expensive faults alike, a proper scan-based diagnosis is the best money you can spend — it turns a guess into a precise, fair quote.
Will the Fog Light Indicator reset itself on a Volvo S90?
Occasionally, yes — a Volvo S90 can extinguish the Fog Light Indicator by itself when the monitored value returns to normal. But a light that keeps coming back is a clear sign of an unresolved issue that needs a proper diagnosis rather than repeated resets.
