Reduced Engine Power Light

This light comes on when a noticeable reduction in the vehicle’s performance occurs.
The vehicle can be driven at a reduced speed when the reduced engine power light is on, but acceleration and speed may be reduced.
The performance may be reduced until the next time you drive your vehicle. If this light stays on, see your dealer as soon as possible for diagnosis and repair.
This light may also come on if there is a problem with the Electronic Throttle Control (ETC) system. If this happens, take the vehicle in for service as soon as possible.
