How Urgent Is the Water in Fuel Light (Diesel)?
Urgency level for this indicator on the Ford Kuga: moderate. Reading the colour is the fastest gut-check — a red symbol asks you to stop and investigate quickly, while amber or yellow means schedule a check soon rather than immediately. Green and blue symbols are simply telling you a system is active. Whatever the colour, the safest habit is to note when the Water in Fuel Light (Diesel) appeared, how the Ford Kuga is behaving, and whether the light is steady or flashing, because a flashing warning almost always means act now.
