Frequently Asked Questions
Why is the Door Ajar Warning Light on in my Honda S2000?
On a Honda S2000, the Door Ajar Warning Light comes on because a monitored value crossed a threshold the car considers abnormal.

Short answer: sometimes, but not indefinitely. Given this indicator's low priority, respect the warning colour and the car's behaviour. When in doubt with your Honda S2000, the safe choice is to stop and have it checked rather than risk further damage.
