WARNING LIGHTS AND CHIMES
Service engine soon
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). 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, one of the engine’s emission control systems may be
malfunctioning. The light may illuminate without a driveability concern
being noted. The vehicle will usually be drivable and will not require
towing.
What you should do if the Service Engine Soon light illuminates
Light turns on solid:
This means that the OBD II system has detected a malfunction.
Temporary malfunctions may cause your Service Engine Soon light 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.
3. The fuel cap may not have been properly installed and securely
tightened.
