Door Ajar Warning Light on a Aston Martin DBS
This is usually informational. Address it at your convenience.
What the Door Ajar Warning Light Means on a Aston Martin DBS
The door-ajar light on a Aston Martin DBS 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 Aston Martin DBS: 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 Aston Martin DBS 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?
Safe-to-drive depends on judgement, and here is the technician's version for a Aston Martin DBS: respect the colour, respect the behaviour.

If everything feels normal and the light is amber, a short, cautious drive to a garage is typically fine, provided you do not delay the actual diagnosis.
Professional Mechanic Tips
Wiring that flexes in the door hinge boot can fray; wiggle-test it if the light flickers over bumps.
On a Aston Martin DBS the door light that will not clear is nearly always a worn jamb switch in the latch — spray it clean first, replace if needed.
