Engine Oil
If this symbol, along with
the LOW OIL LEVEL
message appears on
the Driver Information
Center (DIC), it means
you need to check
your engine oil level
right away.
For more information, see LOW OIL LEVEL under
DIC Warnings and Messages on page 3-69.
You should check your engine oil level regularly; this is
an added reminder.
Checking Engine Oil
It is a good idea to check your engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop. See
Engine Compartment Overview on page 5-12for
the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towel
or cloth, then push it back in all the way. Remove it
again, keeping the tip down, and check the level.

When to Add Engine Oil
If the oil is at or below the cross-hatched area at the
tip of the dipstick, then you will need to add at least
one quart of oil. But you must use the right kind. This
section explains what kind of oil to use. For engine
oil crankcase capacity, seeCapacities and
Specications on page 5-108.
Notice:Do not add too much oil. If your engine
has so much oil that the oil level gets above
the cross-hatched area that shows the proper
operating range, your engine could be damaged.SeeEngine Compartment
Overview on page 5-12
for the location of the
engine oil ll cap.
Be sure to add enough oil to put the level somewhere
in the proper operating range in the cross-hatched area.
Push the dipstick all the way back in when you are
through.

Automatic Transaxle Fluid
When to Check and Change
A good time to check the automatic transaxle uid level
is when the engine oil is changed.
Change both the uid and lter 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 90°F (32°C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police or delivery
service.
If the vehicle is not used under any of these
conditions, change the uid and lter at
100,000 miles (166 000 km).
SeeScheduled Maintenance on page 6-4.
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 uid can damage the
transaxle. Too much can mean that some of the
uid could come out and fall on hot engine or
exhaust system parts, starting a re. Too little uid
could cause the transaxle to overheat. Be sure
to get an accurate reading if you check the
transaxle uid.
Wait at least 30 minutes before checking the transaxle
uid level if you have been driving:
When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
In heavy traffic — especially in hot weather.
While pulling a trailer.
To get the right reading, the uid should be at normal
operating temperature, which is 180°F to 200°F
(82°C to 93°C).
Get the vehicle warmed up by driving about
15 miles (24 km) when outside temperatures are
above 50°F (10°C). If it is colder than 50°F (10°C),
you may have to drive longer.

How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transaxle uid to use. SeeRecommended Fluids
and Lubricants on page 6-12.
If the uid level is low, add only enough of the proper
uid to bring the level into the crosshatched area on
the dipstick.
1. Pull out the dipstick.
2. Using a long-neck funnel, add enough uid at
the dipstick hole to bring it to the proper level.
It does not take much uid, generally less than
one pint (0.5 L).Do not overll.
Notice:Use of automatic transaxle uid labeled
other than DEXRON
®-III, Approved for the
H-Specication, may damage your vehicle, and
the damages may not be covered by your warranty.
Always use automatic transaxle uid labeled
DEXRON
®-III, Approved for the H-Specication.
3. After adding uid, recheck the uid level as
described under “How to Check,” earlier in
this section.
4. When the correct uid level is obtained, push the
dipstick back in all the way.
Engine Coolant
The cooling system in the vehicle is lled with
DEX-COOL®engine coolant. This coolant is designed
to remain in the vehicle for ve years or 150,000 miles
(240 000 km), whichever occurs rst, if only
DEX-COOL
®extended life coolant is added.
The following explains the cooling system and how to
add coolant when it is low. If there is a problem
with engine overheating or if coolant needs to be added
to the radiator, seeEngine Overheating on page 5-27.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®engine coolant will:
Give freezing protection down to−34°F (−37°C).
Give boiling protection up to 265°F (129°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.
Notice:Using coolant other than DEX-COOL
®may
cause premature engine, heater core or radiator
corrosion. In addition, the engine coolant may
require changing sooner, at 30,000 miles (50 000 km)
or 24 months, whichever occurs rst. Any repairs
would not be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your vehicle.
