Your vehicle has a reduced engine power light.

This light, along with the service vehicle soon light, will be displayed when a noticeable reduction in the vehicle's performance may occur. Stop the vehicle and turn off the ignition. Wait for 10 seconds and restart your vehicle. This may correct the condition. See Service Vehicle Soon Light for more information.

The vehicle may 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/retailer as soon as possible for diagnosis and repair.
