If the service engine soon light and reduced engine power lights are on, the throttle may be disabled, and a noticeable change in the vehicle's performance may occur.

If the reduced engine power light is on, but there is no change 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 slower speed while the reduced engine power light is on, but acceleration and speed may be limited.

Anytime the service engine soon light stays on, the vehicle should be taken to an authorized Isuzu dealer as soon as possible for service.
