Power Steering Warning Light on a Jaguar XK
Have this checked promptly. It is not an immediate stop, but do not ignore it for long.
What the Power Steering Warning Light Means on a Jaguar XK
On the Jaguar XK, this light indicates a problem with the power steering — hydraulic (low fluid) on older cars, or electronic on modern ones. You can still steer, but with noticeably more effort.
How Urgent Is the Power Steering Warning Light?
Urgency level for this indicator on the Jaguar XK: high. 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 Power Steering Warning Light appeared, how the Jaguar XK is behaving, and whether the light is steady or flashing, because a flashing warning almost always means act now.
Common Symptoms Alongside the Power Steering Warning Light

- Have an electronic system diagnosed if the light returns
Is It Safe to Drive With the Power Steering Warning Light On?
