- Address the Issue Promptly: If the yellow warning light is illuminated, it's important to address the issue as soon as possible. Ignoring the light can lead to further damage and more costly repairs down the line.
- Avoid Driving Aggressively: If the yellow warning light is illuminated, it's best to avoid driving aggressively or putting excessive strain on the vehicle's systems until the problem is resolved.
