FAQs About Volkswagen Jetta Warning Lights
- What should I do if multiple warning lights come on at once?
If multiple red lights illuminate, stop driving immediately and call for assistance. For yellow lights, have your Jetta inspected as soon as possible. - Can I reset warning lights myself?
Some lights may reset after addressing the issue (like refilling fluids), but many require professional diagnostic tools to reset properly. - How often should I check if all warning lights are working?
