What does a red dashboard light mean?

Red dashboard lights indicate serious issues that require immediate attention. These include oil pressure, engine temperature, and brake system warnings. Pull over safely and address the issue before continuing to drive.

Can I drive with the check engine light on?

A steady check engine light is usually safe for short drives but should be diagnosed soon. A flashing check engine light indicates a serious problem — reduce speed and have the vehicle checked immediately.

How do I reset dashboard warning lights?

Some lights reset automatically after fixing the issue. Others require an OBD-II scanner to clear the code. Always diagnose and fix the underlying problem before attempting to reset any warning light.
