This is usually informational. Address it at your convenience.
What the Door Ajar Warning Light Means on a Toyota C-HR
The door-ajar light on a Toyota C-HR indicates a door (or the boot/bonnet) is not fully latched. It is a safety and security warning, and a stubborn one usually means a door switch or latch sensor has failed.
How Urgent Is the Door Ajar Warning Light?
Urgency level for this indicator on the Toyota C-HR: low. Reading the colour is the fastest gut-check — a red symbol asks you to stop and investigate quickly, while amber or yellow means schedule a check soon rather than immediately. Green and blue symbols are simply telling you a system is active. Whatever the colour, the safest habit is to note when the Door Ajar Warning Light appeared, how the Toyota C-HR is behaving, and whether the light is steady or flashing, because a flashing warning almost always means act now.
