Engine Power Messages
ENGINE POWER IS REDUCED
This message displays and a chime may sound when the cooling system temperature gets too hot and the engine further enters the engine coolant protection mode. See Engine Overheating on page 10‑23 for more information.

If this message is on, but there is no reduction in performance, proceed to your destination. The performance may be reduced the next time the vehicle is driven. The vehicle may be driven at a reduced speed while this message is on, but acceleration and speed may be reduced. Anytime this message stays on, the vehicle should be taken to your dealer for service as soon as possible.
