SERVICE ENGINE SOON

Your vehicle is equipped with a computer that monitors the engine's emission control system. This is commonly known as the On Board Diagnostic System (OBD II). This OBD II system protects the environment by ensuring that your vehicle continues to meet government emission standards. The OBD II system also assists the service technician in properly servicing your vehicle.

The SERVICE ENGINE SOON indicator light illuminates when the ignition is first turned to the ON position to check the bulb. If it comes on after the engine is started, on of the engine's emission control systems may be malfunctioning. The light may illuminate without a driveability concern being noted. The vehicle will ususally be drivable and will not require towing.
