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.

the air cleaner base.
2. Close the cover and make sure that both latches are
secure and fully engaged.

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.

The transaxle fluid cap is
located next to the radiator
hose and below the engine
air cleaner/filter assembly
on the driver's side of
the engine. See ªEngine
Compartment Overviewº
in the Index for more
information on location.
1. After removing the air cleaner/filter assembly
to reach the transaxle fluid cap, turn the cap
counterclockwise to remove. Pull out the dipstick
and wipe it with a clean rag or paper towel.
2. Push it back in all the way, wait three seconds and
then pull it back out again.
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 and turn
the handle clockwise. Reinstall the engine
air cleaner/filter assembly.
