Engine Air Cleaner/Filter
The engine air cleaner/filter is in the engine
compartment on the driver's side of the vehicle, near the
front. See ªEngine Compartment Overviewº in the
Index for more information on location.The engine air cleaner/filter needs replacement
periodically. Use the information listed in this manual
as a guide for filter replacement intervals.
See ªMaintenance Scheduleº in the Index for more
information. In general, you should change the filter
whenever the indicator located on the cover turns
black. See the previous photo for the exact location
of the indicator.
The indicator may turn black earlier or later than the
suggested replacement intervals listed under
ªMaintenance Scheduleº in this manual. However, you
should replace the filter and reset the indicator once the
indicator turns black.
To check or replace the filter, do the following:
1. Remove the two screws located on the sides
of the cover.
2. Lift the cover off.

6-18
3. Pull out the old engine air cleaner/filter.
4. Install a new engine air cleaner/filter, if needed. See
ªNormal Maintenance Replacement Partsº later in
this section for the correct part number for the filter.
5. If the filter is replaced, reset the indicator by
pressing upward on the indicator from the bottom.
6. Reinstall the cover by reversing Steps 1 and 2.
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
The passenger compartment air filter traps most of the
pollen from the air entering your vehicle. Like your
vehicle's engine air cleaner/filter, it needs to be changed
periodically. For how often to change the passenger
compartment air filter, see ªScheduled Maintenance
Servicesº in the Index.
The passenger compartment air filter is located
underneath the hood below the windshield wiper arm on
the passenger's side of the vehicle. See ªEngine
Compartment Overviewº in the Index for more
information on location.
Use the procedure listed below to replace the passenger
compartment air filter:
1. Turn the ignition to ON with the engine off.2. Turn on the windshield wipers and turn them off
again when the wipers are in the out
-wipe position.
The wipers will be straight up and down on
the windshield.
This will allow you access to the leaf screen
under which is located the passenger compartment
air filter.
3. Open the hood to access the engine compartment.
See ªHood Releaseº listed earlier in this section for
more information.
4. Remove the four screws that hold the leaf screen in
place and lift off the screen by lifting and sliding
toward the center of the vehicle.
5. Pull out on the two tabs located on each end of the
filter cover.
6. Lift the filter cover off by pulling it straight upward.
7. Remove the old filter and insert a new one. Make
sure the arrow on the filter is pointing toward the
passenger compartment.
See ªNormal Maintenance Replacement Partsº
later in this section for the correct part number for
the filter.
8. Reverse Steps 1 through 6 to reinstall the cover.

Automatic Transmission Fluid
It is not necessary to check the transmission fluid level.
A transmission fluid leak is the only reason for fluid
loss. If a leak occurs, take your vehicle to the dealership
service department and have it repaired as soon as
possible. You may also have your fluid level checked
by your dealer or service center when you have your
oil changed.
Change both the fluid and filter every 50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:
In heavy city traffic where the outside temperature
regularly reaches 90F (32C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not require changing.NOTICE:
We recommend you use only fluid labeled
DEXRON-III, because fluid with that label is
made especially for your automatic transmission.
Damage caused by fluid other than
DEXRON
-III is not covered by your new
vehicle warranty.
