I think you are confusing DEADLINE and SCHEDULED items. For items with
a deadline, you can indeed add a warning time specifier, as in 

,----
| ** Deadline
|    DEADLINE: <2009-01-15 Thu -0d>
`----

Which means that the deadline warning will first show up on your
agenda on the day it is due, or 

,----
| ** Deadline
|    DEADLINE: <2009-01-15 Thu -3d>
`----

Which means the warning will show up three days before the item is
due.

- Scheduled items first show up on the agenda on the day they are
scheduled and every day thereafter until they are marked done.

- Deadline warnings show up on the agenda n days before the deadline,
with n specified in the variable org-deadline-warning-day or via the
negative modifier in the examples above.

Hope this helps,
