I'm driving a Suzuki Celerio 1,000 c.c auto that has a warning buzzer if

Is it possible to increase the volume of the warning device? I would
ask the garage but I'm not due there for some months.

It's most likely a piezo sounder. Connecting another in parallel could help if the driver can run them both at resonance. If. Otherwise you could add a new piezo driver triggered by the old one. With hearing damage you're likely to be beter off choosing a larger and thus lower frequency piezo.

The size of the market for this is one, you're it, so you won't find anything ready made.

Personally I wish all such things were banished from cars. I've always looked back to see the lights aren't on, what's so hard about that.
