For this I believe you just need to setup the error page or if you have already setup the error page you just need to add the entry for 503 error code in your web.config’s httpErrors section as shown.

<httpErrors errorMode="Custom" existingResponse="Replace">
<error statusCode="503" path="App_Offline.htm" responseMode="File" />
Hope this will fix your issue.
