This alert is crucial for ensuring your car operates safely and efficiently. Understanding what this warning means, its possible causes, and how to address it is essential for any owner experiencing this issue.

Understanding the Warning

When the "Check Hybrid System" warning appears, it generally signifies that the vehicle's onboard computer has detected a fault within the hybrid system. This could manifest in various ways, including reduced performance or changes in how the vehicle operates. The warning light can appear in different colors:

  • Yellow: Indicates a non-critical issue that requires attention soon.

Ignoring this warning could lead to further complications or damage to the vehicle.

Common Causes of the Warning

Several factors can trigger the "Check Hybrid System" alert. Here are some of the most common issues:

  • Battery Issues: Aging or faulty hybrid batteries may not provide sufficient power, triggering the warning.
  • Coolant Levels: Low coolant levels in the inverter cooling system can also prompt this warning.
