6-17 What to Do with Used Oil
Used engine oil contains certain elements that may be
unhealthy for your skin and could even cause cancer.
Don't let used oil stay on your skin for very long. Clean
your skin and nails with soap and water, or a good hand
cleaner. Wash or properly throw away clothing or rags
containing used engine oil. See the manufacturer's
warnings about the use and disposal of oil products.
Used oil can be a threat to the environment. If you
change your own oil, be sure to drain all the oil from
the filter 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 your used oil, ask
your dealer, a service station or a local recycling center
for help.
Engine Air Cleaner/Filter
The engine air cleaner/filter is in the engine
compartment on the driver's side of the vehicle. See
ªEngine Compartment Overviewº in the Index for more
information on location.

6-18
To check or replace the engine air cleaner/filter do
the following:
1. Loosen the two clips on top of the engine air
cleaner/filter housing and lift the filter cover tabs out
of the housing.
2. Push the housing cover toward the engine,
compressing the hose.
3. Pull out the filter. Check or replace the engine
air cleaner/filter.
4. To reinstall the housing cover, make sure the filter
cover tabs position through the slots in the housing.
A notch on the sides of the filter cover will indicate
the correct engagement.
5. Fasten the two clips on the top of the housing when
you are finished.
Refer to the Maintenance Schedule to determine when to
replace the air filter.
See ªScheduled Maintenance Servicesº in the Index.
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 stops flame if
the engine backfires. If it isn't there, and the
engine backfires, you could be burned. Don't
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're driving.

Passenger Compartment Air Filter
(If Equipped)
The passenger compartment air filter removes certain
particles from the air, including pollen and dust
particles. Reductions in airflow, which may occur more
often in dusty areas, indicate that the filter may need to
be replaced early.
The filter should be replaced as part of the routine
scheduled maintenance. See ªMaintenance Scheduleº in
the Index for more information.
The passenger compartment
air filter is located on the
passenger side of the
vehicle at the base of the
windshield and can be
accessed through a
removable panel under the
hood of the vehicle.To check or replace the air filter, do the following:
1. With the hood open, unlatch and remove the
access panel.
2. To remove the filter, press on the spring tab on
the side of the filter housing and pull the filter out
of the housing.
3. To install the new filter, press on the spring tab and
insert the filter into the housing. The filter should be
fully inserted into the upper and lower grooves and
locked into place by the spring tab.
4. Reinstall the air filter access panel at the base of
the windshield.

Scheduled Maintenance
7-5
Short Trip/City Definition
Follow the Short Trip/City Scheduled Maintenance if
any one of these conditions is true for your vehicle:

Most trips are less than 5 miles (8 km). This is
particularly important when outside temperatures are
below freezing.

Most trips include extensive idling (such as frequent
driving in stop
-and-go traffic).

You frequently tow a trailer or use a carrier on top of
your vehicle.

If the vehicle is used for delivery service, police, taxi
or other commercial application.
One of the reasons you should follow this schedule if
you operate your vehicle under any of these conditions
is that these conditions cause engine oil to break
down sooner.
