Understanding Warning Lights
Understanding warning lights on your hybrid or electric vehicle is crucial for maintaining its health and ensuring your safety. These lights are designed to alert you to various issues and system statuses, allowing you to address problems before they become serious.
Importance of Warning Lights
Warning lights play a vital role in vehicle safety and maintenance. They notify drivers of potential issues that may need immediate attention or scheduled maintenance. Ignoring these alerts can lead to more significant problems, higher repair costs, and even safety risks. For instance, if safety system lights such as ABS and SRS airbag warning lights do not come on when starting the hybrid system, it could indicate that these systems are unavailable to protect in an accident, potentially leading to serious injury or death. In such cases, immediate inspection by a dealer is advised (Toyota).
