Understanding Common Car Maintenance Warning Lights

Every car comes with a unique set of warning lights, but some are universal and appear across various makes and models.

Common Warning Lights and Their Meanings:

1. Engine Light:

• Meaning: One or more tires are under-inflated or over-inflated.

6. Oil Pressure Light:

What to Do When a Warning Light Appears

1. Pull Over Safely: If possible, pull over to a safe location and turn off the engine.
2. Refer to Your Owner’s Manual: Your owner’s manual provides detailed information about the meaning of each warning light and recommended actions.
3. Assess the Situation: Try to identify any unusual sounds, smells, or other symptoms that may indicate the source of the problem.
4. Contact a Mechanic: If you can’t determine the cause of the warning light, contact a qualified automotive technician.

“It’s always better to err on the side of caution,” advises seasoned mechanic, Sarah Johnson. “A quick call to a mechanic can save you from potential costly repairs down the road.”

Preventative Car Maintenance: Early Detection and Intervention

Regular car maintenance is essential for keeping your vehicle running smoothly and minimizing the risk of major breakdowns. These preventative steps can help catch potential problems early and reduce the chance of warning lights appearing:

• Regular Oil Changes: Follow your vehicle’s recommended oil change schedule.
