Toyota Warning Lights Explained
A light just came on in your Toyota. This guide sorts the common Toyota warning lights into three groups: the ones Toyota says need action right away, the malfunction lights to book a check for, and the indicators that are mostly information. Meanings come from Toyota's Warning Lights page, read October 26, 2026.
Red or yellow: what is the difference?
Toyota says red icons mark a condition that needs immediate attention, such as an open door or low engine oil pressure, while yellow icons mark an item of importance, such as low fuel, that is not necessarily a warning. Your owner's manual shows every symbol for your model.

When a safety light stays dark at start-up
Safety lights such as the ABS and SRS airbag warning lights should come on briefly when you start the vehicle. Toyota warns that if one of them does not come on (Toyota's wording: when you start the hybrid system), those systems may not be available to help protect you in an accident, which Toyota says could result in death or serious injury. Toyota's instruction is to have the vehicle inspected by a Toyota dealer immediately if this happens.
