affect the vehicle’sabilitytopass
an Emissions Inspection/
Maintenance test. See
Accessories and
Modifications0352.
If the light is flashing :Amalfunction has been detected thatcould damage the emission controlsystem and increase vehicleemissions. Diagnosis and servicemay be required.
To h e l p p r e v e n t d a m a g e , r e d u c evehicle speed and avoid hardaccelerations and uphill grades.
If towing a trailer, reduce theamount of cargo being hauled assoon as possible.
If the light continues to flash, find asafe place to park. Turn the vehicleoff and wait at least 10 secondsbefore restarting the engine. If thelight is still flashing, follow theprevious guidelines and see yourdealer for service as soon aspossible.
If the light is on steady :Amalfunction has been detected.Diagnosis and service may berequired.
Check the following:
.If fuel has been added to thevehicle using the capless funneladapter, make sure that it hasbeen removed. See“Filling theTa n k w i t h a P o r t a b l e G a s C a n”underFilling the Tank0313.The diagnostic system candetect if the adapter has beenleft installed in the vehicle,allowing fuel to evaporate intothe atmosphere. A few drivingtrips with the adapter removedmay turn off the light.
.Poor fuel quality can causeinefficient engine operation andpoor driveability, which may goaway once the engine is warmedup. If this occurs, change thefuel brand. It may require atleast one full tank of the properfuel to turn the light off. SeeFuel0311.
If the light remains on, see yourdealer.
