What the Door Ajar Warning Light Means on a Acura NSX
On the Acura NSX, this symbol shows an open or improperly closed door. If all doors are shut but the light stays on, a worn door switch is the usual culprit.
How Urgent Is the Door Ajar Warning Light?
Urgency level for this indicator on the Acura NSX: 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 Acura NSX is behaving, and whether the light is steady or flashing, because a flashing warning almost always means act now.

Is It Safe to Drive With the Door Ajar Warning Light On?
Whether it is safe to keep driving your Acura NSX with the Door Ajar Warning Light on comes down to urgency (low) and behaviour. As a rule, if the light is red or flashing, or the Acura NSX is running poorly, stop somewhere safe and arrange help rather than pushing on.

Can I keep driving with the Door Ajar Warning Light on?
