Do not make any unauthorized changes to your vehicle or engine. By

law, vehicle owners and anyone who manufactures, repairs, services,

sells, leases, trades vehicles, or supervises a fleet of vehicles are not

permitted to intentionally remove an emission control device or prevent

it from working. Information about your vehicle’s emission system is on

the Vehicle Emission Control Information Decal located on or near the

engine. This decal also lists engine displacement.

Please consult your Warranty Guide for complete emission warranty

information.

On-board diagnostics (OBD-II)

Your vehicle is equipped with a computer that monitors the engine’s

emission control system. This system is commonly known as the

on-board diagnostics system (OBD-II). The OBD-II system protects the

environment by ensuring that your vehicle continues to meet

government emission standards. The OBD-II system also assists your

authorized dealer in properly servicing your vehicle. When the service

engine soon

indicator illuminates, the OBD-II system has detected

a malfunction. Temporary malfunctions may cause the service engine

soon

indicator to illuminate. Examples are:

1. The vehicle has run out of fuel—the engine may misfire or run poorly.

2. Poor fuel quality or water in the fuel—the engine may misfire or run

poorly.

3. The fuel cap may not have been securely tightened. See Fuel filler

cap in this chapter.

4. Driving through deep water—the electrical system may be wet.

These temporary malfunctions can be corrected by filling the fuel tank

with good quality fuel, properly tightening the fuel cap or letting the

electrical system dry out. After three driving cycles without these or any

other temporary malfunctions present, the service engine soon

indicator should stay off the next time the engine is started. A driving

cycle consists of a cold engine startup followed by mixed city/highway

driving. No additional vehicle service is required.

If the service engine soon

indicator remains on, have your vehicle

serviced at the first available opportunity. Although some malfunctions

detected by the OBD-II may not have symptoms that are apparent,

continued driving with the service engine soon

indicator on can

result in increased emissions, lower fuel economy, reduced engine and

transmission smoothness, and lead to more costly repairs.
