In this comprehensive guide, we will decode these warning lights and provide insights into what they mean for your vehicle’s safety and performance.

Understanding Warning Lights

Red Warning Lights: Immediate Attention Required: Red warning lights demand immediate action. When one of these lights comes on and stays on while driving, or when a gauge shows a problem, it’s crucial to take prompt action.

Yellow Warning Lights: Caution Advised: Yellow warning lights indicate issues that require attention but aren’t emergencies.

Green and White Lights: Information and Status: Green and white lights provide information and indicate the status of various vehicle features.

Charging System Light

This light briefly comes on when you start the vehicle but should go out when the engine starts. If it stays on or illuminates while driving, there may be an issue with the electrical charging system. Have it checked by your dealer to prevent battery drain.

Malfunction Indicator Lamp (Check Engine Light)

This light is part of the vehicle’s emission control system. If it stays on while the engine is running, a malfunction has been detected, and your vehicle may require service. Ignoring it can lead to damage and lower fuel efficiency.

Brake System Warning Light

This light should briefly come on when you start the vehicle. If it remains on or comes on while driving, there’s a brake problem. Stop the vehicle safely and have the brake system inspected.
