3-6 Air Conditioning
On hot days, open the windows long enough to let hot
air inside escape. This reduces the time it takes for your
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.
The A/C mode allows the air coming into your vehicle
to be cooled. This mode is useful for normal cooling
on hot days.
Use A/C with recirculation on to allow the air inside
your vehicle to be recirculated. This mode will help to
maximize your air conditioner's performance and your
vehicle's fuel economy. This mode also cools the air the
fastest and can be used to keep unwanted odors and/or
dust from entering the vehicle.
When using the air conditioner, in manual mode, turn
off the recirculation mode and use the outside air mode
after the vehicle reaches a comfortable interior
temperature. When the right knob on the control panel
is between floor and defrost, the recirculation feature
will not function. This helps reduce window fogging.
Passenger Compartment Air Filter
Your vehicle is equipped with a passenger compartment
air filter which filters outside air entering the vehicle.
For information on replacing the filter see ªPassenger
Compartment Air Filterº in the Index.
Heating
The heater works best if you keep your windows closed
while using it. On cold days, when using manual mode,
use the floor or bi
-level mode with the temperature knob
in the red area.
On cold days, approximately 32F (
-0C) or lower,
you may experience differences in how the transmission
shifts until the engine is warm. This feature automatically
reduces the time it takes for the engine to reach normal
operating temperature and shortens the time it takes the
heater to reach full output.
If you use the engine coolant heater before starting
your engine in cold weather, 20F (
-8C) or lower,
the heating system will produce warmer air faster to
heat the passenger compartment.
The use of an engine coolant heater also reduces the
time it takes for the engine to reach normal operating
temperature. For more information, see ªEngine Coolant
Heaterº in the Index.

If the CHECK ENG OIL
LEVEL message appears
on the instrument cluster,
it means you need to check
your engine oil level
right away.

Engine Air Cleaner/Filter
The engine air cleaner/filter assembly has an air filter
restriction indicator that lets you know when the engine
air cleaner/filter is dirty and needs to be serviced. The
air filter restriction indicator is located on the air filter
assembly cover. 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 air filter restriction
indicator.
The service window (A)
with the percentage scale
shows the amount of engine
air cleaner/filter life used.
When both service window (A) and service window (B)
turn orange, replace the engine air cleaner/filter.After changing the engine air cleaner/filter, press the
button on top of the air filter restriction indicator to reset it.
Your engine air cleaner/filter is located in the air filter
housing near the front corner of the engine compartment
on the passenger's side of the vehicle. See ªEngine
Compartment Overviewº in the Index for more
information on location.

1. To remove the engine air cleaner/filter, loosen the
screws on the cover.
2. Lift the cover upward and remove the engine air
cleaner/filter out of the air cleaner housing. Care
should be taken to dislodge as little dirt as possible.
3. Clean the filter sealing surface and the housing.
4. Install the new engine air cleaner/filter.
5. Install the cover and tighten the screws.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.

Passenger Compartment Air Filter
The filter is located under the instrument panel below
the glove compartment.
To replace the passenger compartment air filter do the
following:
1. Remove the bolts on the access panel and set the
panel aside. Because this operation can be a little
difficult, you may choose to have it done at your
dealer's service department.
2. Reach under the
instrument panel
towards the front of
the vehicle and pull
downward on the filter
retaining bracket.
3. Remove the air filter by pulling downward on the
element. Remove the second portion of the air filter
by sliding it towards the rear of the vehicle and then
pulling downward.4. Install the new filter by reversing the steps listed
previously. Be sure to follow any instructions that
may be included in the replacement filter package.
Refer to the Maintenance Schedule to determine
when to replace the passenger compartment air filter.
See ªScheduled Maintenanceº in the Index.
Automatic Transmission Fluid
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) 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, change the fluid and filter every
100,000 miles (166 000 km).
See ªScheduled Maintenance Servicesº in the Index.
