What does it mean when the amber restricted performance light comes on on a XKR?

When the amber restricted performance light comes on in a Jaguar XKR, it typically indicates that the vehicle's engine management system has detected a problem that affects performance, triggering a temporary limp mode. This can be caused by various issues, such as a malfunctioning sensor, low fluid levels, or other mechanical concerns. It's important to have the vehicle diagnosed using an OBD-II scanner to identify the specific problem and address it promptly to restore full performance. Ignoring this warning could lead to further damage or reduced drivability.
