2007 BUICK LACROSSE air filter

Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil from
the lter before disposal. Never dispose of oil by
putting it in the trash, pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle it by taking it to a place that collects used
oil. If you have a problem properly disposing of
used oil, ask your dealer, a service station or a local
recycling center for help.

The engine air cleaner/lter is located in the

How to Inspect the Engine
Air Cleaner/Filter
To inspect the air cleaner/lter, remove the lter
from the vehicle and lightly shake the lter to
release loose dust and dirt. If the lter remains
caked with dirt, a new lter is required.
To inspect or replace the engine air cleaner/lter
do the following:
1. Lift the lter cover tabs on top of the engine
air cleaner/lter housing.
2. Push the lter cover housing toward the
engine.
3. Pull out the lter.
4. Inspect or replace the engine air cleaner/lter.
SeeNormal Maintenance Replacement Parts
on page 471.
5. To reinstall the cover, position the tabs
through the slots on the housing. A notch
on the sides of the lter cover will indicate
the correct engagement.
6. Push the cover tabs on top of the housing
to lock the cover in place.
{CAUTION:
Operating the engine with the air
cleaner/lter off can cause you or others
to be burned. The air cleaner not only
cleans the air; it helps to stop ames if
the engine backres. If it is not there
and the engine backres, you could be
burned. Do not drive with it off, and be
careful working on the engine with the
air cleaner/lter off.
Notice:If the air cleaner/lter is off, a backre
can cause a damaging engine re. And, dirt
can easily get into your engine, which will
damage it. Always have the air cleaner/lter in
place when you are driving.
