Dashboard warning lights
Grouped by what they demand of you, not alphabetically. If a light just came on and you are deciding whether to keep driving, the answer is near the top of this page.
Colour is the fastest first read: red generally means stop or act now, amber and yellow mean a fault needs attention, green and blue are usually telling you a system is switched on. Manufacturers vary, so the colour is a strong hint rather than a rule.
The warning light reference is temporarily unavailable.
