Cadillac 2008 DTS - Manual (Page 313)

Follow these steps to reinstall the cover to the engine
air cleaner/filter housing:
1. Align the two hinges located on the inboard side
of the cover.
2. Push the cover slightly down and towards the
engine to engage the tabs in the hinges and
align the two screws.
3. Tighten the two screws on the top of the engine
air cleaner/filter housing cover.
{ CAUTION:
Operating the engine with the air cleaner/filter
off can cause you or others to be burned.
The air cleaner not only cleans the air; it helps
to stop flames if the engine backfires. If it is
not there and the engine backfires, you could
be burned. Do not drive with it off, and be
careful working on the engine with the air
cleaner/filter off.
Notice: If the air cleaner/filter is off, a backfire can
cause a damaging engine fire. And, dirt can easily get
into your engine, which will damage it. Always have
the air cleaner/filter in place when you are driving.
