How to Reset the Change Engine Oil Message
1. With the ignition key in RUN but the engine off,
repeatedly push the trip/reset button until OIL
is displayed.
2. Once OIL is displayed, push and hold the trip/reset
button for five seconds. The number will disappear
and be replaced by 100 (indicating 100% oil
life remaining).
3. Turn the key to OFF.
If the change engine oil message comes back on,
the engine oil life monitor has not reset.
Repeat the procedure.What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don't let used oil stay on your skin
for very long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly throw
away clothing or rags containing used engine oil.
See the manufacturer's warnings about the use and
disposal of oil products.
Used oil can be a real threat to the environment. If you
change your own oil, be sure to drain all free
-flowing
oil from the filter before disposal. Don't ever dispose of
oil by putting it in the trash, pouring it on the ground,
into sewers, or into streams or bodies of water. Instead,
recycle it by taking it to a place that collects used oil.
If you have a problem properly disposing of your used
oil, ask your dealer, a service station or a local recycling
center for help.

Engine Air Cleaner/Filter
The engine air cleaner/filter is located at the front of the
engine compartment, on the driver's side of the vehicle,
under the engine coolant reservoir. See ªEngine
Compartment Overviewº in the Index for more
information on location.
Checking or Replacing the Engine Air Cleaner/Filter
1. Unlatch the two hooks on top of the air cleaner housing.
2. Turn back the air inlet panel and rest it on top of the
housing. The air intake tube is designed to flex back;
you do not need to disconnect it.3. After replacing the engine air cleaner/filter, seat the tabs
on the bottom of the panel into the slots on the housing.
4. Latch the hooks to secure the panel in place. If the
panel moves easily, check that the tabs are seated
correctly in the slots.
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 Replacement
Passenger compartment air, both outside and
recirculated air, is routed through a passenger
compartment filter, which is part of a two
-piece filter
system. The filter removes certain contaminants from
the air, including pollen and dust particles, as well as
odors such as exhaust or fuel fumes. Reductions in
airflow, which may occur more quickly in dusty areas,
indicate that the filter needs to be replaced early. For
how often to change the passenger compartment air
filter, see ªScheduled Maintenanceº in the Index.
The access panel for the passenger compartment air
filter is located in the back of the glove box.
1. Pull the tab up and out on the outer access panel.

6-19
2. Then push the tab, located on the left of the inner
access panel, to the right.3. The first air filter will pull straight out. To remove
the second, reach in and slide it toward the opening.
Pull the second filter out.
4. Replace the filters by reversing Step 3. Make sure
the filters are inserted so that the sealing foam is
angled in the same direction on both filters. For the
type of filter to use, see ªNormal Maintenance
Replacement Partsº in the Index.
5. Close the inner access door, while squeezing the tab.
Be sure it is tightly closed.
6. Snap the outer access panel into the back of the
glove box.

Automatic Transaxle Fluid
When to Check and Change
A good time to check your automatic transaxle 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 at
100,000 miles (166 000 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.
NOTICE:
Too much or too little fluid can damage your
transaxle. Too much can mean that some of the
fluid could come out and fall on hot engine parts
or exhaust system parts, starting a fire. Be sure
to get an accurate reading if you check your
transaxle fluid.
Wait at least 30 minutes before checking the transaxle
fluid level if you have been driving:

When outside temperatures are above 90F (32C).

At high speed for quite a while.

In heavy traffic
-- especially in hot weather.

While pulling a trailer.

6-21
To get the right reading, the fluid should be at normal
operating temperature, which is 180F to 200F
(82C to 93C).
Get the vehicle warmed up by driving about 15 miles
(24 km) when outside temperatures are above 50F
(10C). If it's colder than 50F (10C), you may
have to drive longer.
Checking the Fluid Level
Prepare your vehicle as follows:

Park your vehicle on a level place. Keep the
engine running.

With the parking brake applied, place the shift lever
in PARK (P).

With your foot on the brake pedal, move the shift
lever through each gear range, pausing for about
three seconds in each range. Then, position the
shift lever in PARK (P).

Let the engine run at idle for three to five minutes.Then, without shutting off the engine, follow these steps:
The dipstick is located toward the back of the engine
compartment, next to the brake master cylinder.
The dipstick handle has a bright, red loop design for
easy identification. See ªEngine Compartment Overviewº
in the Index for more information on location.
1. 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.

6-22
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.
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 Index.
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.
NOTICE:
We recommend you use only fluid labeled
DEXRON
-III, because fluid with that label is
made especially for your automatic transaxle.
Damage caused by fluid other than DEXRON

-III
is not covered by your new vehicle warranty.
3. After adding fluid, recheck the fluid level as
described under ªHow to Check.º
4. When the correct fluid level is obtained,
push the dipstick back in all the way.

6-23
Engine Coolant
The cooling system in your vehicle is filled with
DEX
-COOL
engine coolant. This coolant is designed
to remain in your vehicle for 5 years or 150,000 miles
(240 000 km), whichever occurs first, if you add only
DEX
-COOL
extended life coolant.
The following explains your cooling system and how
to add coolant when it is low. If you have a problem
with engine overheating, see ªEngine Overheatingº in
the Index.
A 50/50 mixture of clean, drinkable water and
DEX
-COOL
coolant will:

Give freezing protection down to
-34F (-37C).

Give boiling protection up to 265F (129C).

Protect against rust and corrosion.

Help keep the proper engine temperature.

Let the warning messages and gages work as
they should.
NOTICE:
When adding coolant, it is important that you
use only DEX
-COOL (silicate-free) coolant.
If coolant other than DEX-COOL is added to
the system, premature engine, heater core or
radiator corrosion may result. In addition, the
engine coolant will require change sooner
-- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first. Damage caused by the
use of coolant other than DEX
-COOL is not
covered by your new vehicle warranty.
