Engine Air Cleaner/Filter
(Gasoline Engines)
Your engine air cleaner/filter is located between the
battery and coolant recovery tank. See ªEngine
Compartment Overviewº in the Index for more
information on location.
The engine air cleaner/filter
assembly has an indicator
that lets you know when
the engine air cleaner/filter
is dirty and needs to
be serviced.
The indicator is located in the air intake tube between
the engine air cleaner/filter and the engine. See ªEngine
Compartment Overviewº in the Index for more
information on location.
See ªOwner Checks and Servicesº in the Index to
determine when to check the indicator.
If the area inside the clear section of the indicator is
green, no engine air cleaner/filter service is required.
When the area inside the indicator is orange and
CHANGE AIR FILTER appears, the filter should
be replaced.

6-16
To remove the engine air cleaner/filter do the following:
1. Unhook the two retaining clips and remove the
housing cover.
2. Lift the filter and the connected duct out of the air
cleaner/filter housing. Hold the duct and remove the
filter by both pulling and twisting the filter away
from the duct. Care should be taken to dislodge as
little dirt as possible.
3. Clean the filter sealing surface of the duct and the
filter housing.4. Install the new filter by pushing it all the way to the
stop on the duct.
5. Install the duct and the filter into the engine air
cleaner/filter housing. Make sure that the duct fits
properly into the housing.
6. Install the cover and fasten the two retaining clips.
7. After the engine air cleaner/filter is properly
serviced, the indicator should be reset. Push the
button on top of the indicator to reset it to the
green (clean) filter zone.

6-17
Refer to the Maintenance Schedule to determine when to
replace the engine air cleaner/filter. See ªOwner Checks
and 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.
Automatic Transmission Fluid
If your vehicle has a diesel engine, see ªAutomatic
Transmission Fluidº in the Diesel Supplement.
When to Check and Change
A good time to check your automatic transmission
fluid level is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles (83 000 km).
See ªScheduled Maintenance Servicesº in the Index.
How to Check
Because this operation can be a little difficult,
you may choose to have this done at the dealership
service department.
If you do it yourself, be sure to follow all the
instructions here, or you could get a false reading
on the dipstick.

Scheduled Maintenance

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.

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.
