Pontiac Vibe 2007 Owner's Manual page 289

To inspect or replace the engine air cleaner/filter,
do the following:
1. Release the two clips that hold the cover down.
2. Lift the cover off.
3. Inspect or replace the engine air cleaner/filter.
4. Reinstall the 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.
