Here are the most common methods, but you may need to consult your owner's manual for the precise procedure for your specific vehicle:
* Method 1 (Most Common): Repeated Ignition Cycles
This involves cycling the ignition switch (turning the key to the "on" position, but not starting the car) several times. The typical sequence is to turn the key to "on," wait a few seconds, then turn it off. Repeat this 5-8 times. Sometimes you need to do this with the engine running briefly before turning it off. This method often works for simple oil change indicators.
* Method 2 (Digital Display):
Some 1998 Regals with more advanced instrument panels might have an on-screen menu system to reset the oil life monitor. Look for a "settings" or "options" menu, usually accessed through buttons on the steering wheel or the instrument cluster. Your owner's manual is crucial here. The exact steps will vary greatly depending on the specific features of your car's computer.
* Method 3 (Using a Scan Tool):
A professional-grade OBD-II scan tool can definitely reset the oil life indicator. However, this requires some knowledge of automotive diagnostics and access to such a tool. This is generally the most reliable method. Many auto parts stores will reset this for a small fee.
Important Considerations:
* Actually Change Your Oil: Resetting the light doesn't magically make your oil fresh. Always change your oil according to the manufacturer's recommendations (found in your owner's manual), regardless of the light's status.
* Owner's Manual: Your owner's manual is your best resource. It will provide the exact procedure for your car's model and year.
If none of the above methods work, you might have a more complex issue, and it's best to consult a qualified mechanic. They can diagnose any underlying problems and properly reset the light.
