WARNING!
A hot exhaust system can start a fire if you park over materials that can burn. Such
materials might be grass or leaves coming into contact with your exhaust system.
Do not park or operate your vehicle in areas where your exhaust system can contact
anything that can burn.
Your vehicle has the ability to alert you to additional maintenance required on your
vehicle or engine. The following messages may display in your instrument cluster
display:
•
Perform Service
— Your vehicle will require emissions maintenance at a set
interval. To help remind you when this maintenance is due, the instrument cluster
display will display “Perform Service”. When the “Perform Service” message is
displayed in the instrument cluster display it is necessary to have the emissions
maintenance performed. Emissions maintenance may include replacing the
Closed Crankcase Ventilation (CCV) filter element. The procedure for clearing and
resetting the "Perform Service" indicator message is located in the appropriate
Service Information.
