Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of the windows.

Keep the air path under the front seats clear of
objects. This helps circulate air throughout
your vehicle.
Passenger Compartment Air Filter
Passenger compartment air, both outside air and
recirculated air, is routed through a passenger
compartment filter, which is part of a three
-piece filter
system. The carbon
-treated filter removes certain
contaminants from the air, including pollen and dust
particles. Reductions in airflow, which may occur more
quickly in dusty areas, indicate that the filter needs to be
replaced early.The filter is located inside the air control module, with
an access panel under the instrument panel near the
accelerator pedal. The filter should be replaced as part
of routine scheduled maintenance. See the Maintenance
Schedule booklet for replacement intervals. See your
dealer for details on changing the filter.
Your vehicle will not be damaged if you choose not to
replace the filter once the old one is removed.

Engine Air Cleaner/Filter
The air cleaner is located next to the coolant surge tank
on the driver's side of the engine. Be sure the engine has
cooled before following these steps to replace the air
cleaner filter:
1. Disconnect the Intake
Air Temperature (IAT)
sensor from the clean
air duct.
2. With a screwdriver,
loosen the air duct
clamp, which is located
at the mass airflow
sensor end of the
air duct.
3. Disconnect the air duct from the mass airflow sensor.

4. Unhook both air cleaner cover latches.
5. Move the air cleaner lid out of the way.6. Take out the air cleaner filter and remove any
loose debris that may be found lying in the air
cleaner base.
7. Install a new air filter element. See ªNormal
Maintenance Replacement Partsº in the Index for the
proper type.

6-18
Follow these steps to reinstall the air cleaner assembly:
1. Slide the air cleaner lid into the slots in the bottom of
the air cleaner base.
2. Close the cover and make sure that both latches are
secure and fully engaged.
3. Reinstall the clean air duct over the mass airflow
sensor. Make sure that the duct is secure around the
entire outer edge of the sensor.
4. Tighten the air duct clamp.
5. Reconnect the IAT sensor.
Refer to the Maintenance Schedule to determine when to
replace the air filter.
See ªScheduled Maintenance Servicesº in the
Maintenance Schedule booklet.
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.

3. Check both sides of the dipstick, and read the
lower level. The fluid level must be in the
cross
-hatched area.
4. If the fluid level is in the acceptable range, push the
dipstick back in all the way. Replace the air
cleaner/filter assembly.
How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transaxle fluid to use. See ªRecommended
Fluids and Lubricantsº in the Maintenance
Schedule booklet.
If the fluid level is low, add only enough of the proper
fluid to bring the level into the cross
-hatched area on
the dipstick.
1. Pull out the dipstick.
2. Using a long
-neck funnel, add enough fluid at the
dipstick hole to bring it to the proper level.
It doesn't take much fluid, generally less than
one pint (0.5 L). Don't overfill.
