What the Door Ajar Warning Light Means on a Nissan Leaf
The door-ajar light on a Nissan Leaf 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 Nissan Leaf: 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 Nissan Leaf is behaving, and whether the light is steady or flashing, because a flashing warning almost always means act now.
