Automatic Transmission Fluid
When to Check and Change Automatic
Transmission Fluid
A good time to check your automatic transmission
uid level is when the engine oil is changed.
Check the uid in the transmission and differential at
the intervals listed inPart A: Scheduled Maintenance
Services on page 6-4, and be sure to use the
transmission uid listed inPart D: Recommended
Fluids and Lubricants on page 6-19.
How to Check Automatic
Transmission Fluid
Because this operation can be a little difficult,
you may choose to have this done at the
dealer/retailer 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:Use of the incorrect automatic transmission
uid may damage your vehicle, and the damages
may not be covered by your warranty. Always
use the automatic transmission uid listed in
Part D: Recommended Fluids and Lubricants on
page 6-19.
Wait at least 30 minutes before checking the
transmission 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 158°F to 176°F
(70°C to 80°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.
5-19

Checking the Fluid Level
Prepare your vehicle as follows:
1. Park your vehicle on a level place. Keep the
engine running.
2. With the parking brake applied, place the shift
lever in PARK (P).
3. 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).
4. Let the engine run at idle for three to ve minutes.
Then, without shutting off the engine, follow these steps:
The automatic transmission dipstick has an orange
handle and is located near the front of the engine
compartment. SeeEngine Compartment Overview
on page 5-12for more information on location.
1. Release the tab and 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 uid level must be between the
two dimples in the hot range.
4. If the uid level is in the acceptable range, push
the dipstick back in all the way; then press the
tab down to lock the dipstick in place.
5-20

How to Add Automatic
Transmission Fluid
Refer to the Maintenance Schedule to determine
what kind of transmission uid to use. SeePart D:
Recommended Fluids and Lubricants on page 6-19.
If the uid level is low, add only enough of the proper
uid to bring the level into the area between dimples
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:Too much or too little uid can damage
your transmission. Too much can mean that some
of the uid could come out and fall on hot engine
parts or exhaust system parts, starting a re.
Too little uid could cause the transmission to
overheat. Be sure to get an accurate reading if
you check your transmission uid.3. After adding uid, recheck the uid level as
described under “How to Check Automatic
Transmission Fluid,” earlier in this section.
4. When the correct uid level is obtained, push the
dipstick back in all the way; then press the tab
down to lock the dipstick in place.
Manual Transmission Fluid
When to Check
A good time to have your manual transaxle uid level
checked is when the engine oil is changed. However,
the uid in your manual transaxle does not require
changing.
How to Check
Because this operation can be difficult, you may
choose to have this done at your dealer/retailer
service department.
5-21

If you do it yourself, be sure to follow all the instructions
here, or you could get a false reading.
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.
Check the uid level only when your engine is off, the
vehicle is parked on a level place and the transaxle
is cool enough for you to rest your ngers on the
transaxle case.
Then, follow these steps:
1. Remove the ller plug.
2. Check that the lubricant level is up to the bottom
of the ller plug hole.
3. If the uid level is good, install the plug and be
sure it is fully seated. If the uid level is low,
add more uid as described in the next steps.How to Add Fluid
Here is how to add uid. Refer to the Maintenance
Schedule to determine what kind of uid to use.
SeePart D: Recommended Fluids and Lubricants
on page 6-19.
1. Remove the ller plug.
2. Add uid at the ller plug hole. Add only enough
uid to bring the uid level up to the bottom of
the ller plug hole.
3. Install the ller plug. Be sure the plug is fully seated.
Hydraulic Clutch
The hydraulic clutch linkage in your vehicle is
self-adjusting. The master cylinder reservoir is lled
with DOT-3 brake uid.
It is not necessary to regularly check the uid unless
you suspect there is a leak in the system. Adding uid
will not correct a leak.
The hydraulic clutch and brake master cylinder use the
same reservoir.
A uid loss in this system could indicate a problem.
Have the system inspected and repaired.
5-22

When to Check and What to Use
The reservoir is located
at the back of the engine
compartment, on the
driver’s side of the vehicle.
SeeEngine Compartment
Overview on page 5-12
for more information
on location.
Refer to the Maintenance Schedule to determine
how often you should check the uid level in your
master cylinder reservoir and for the proper uid.
SeePart B: Owner Checks and Services on page 6-12
andPart D: Recommended Fluids and Lubricants
on page 6-19.
How to Check and Add Fluid
Check to make sure that the uid level is at or above
the MIN mark. If the level is below the MIN mark,
see the instructions on the reservoir cap.
Engine Coolant
Your vehicle was factory-lled with a coolant developed
to last for ve years or 150,000 miles (240 000 km),
whichever occurs rst. When coolant is added or
changed, use DEX-COOL
®coolant.
The following explains your cooling system and how
to add coolant when it is low. If you have a problem
with engine overheating, seeEngine Overheating
on page 5-26.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®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.
5-23

What to Use
Use a mixture of one-half clean, drinkable water and
one-half DEX-COOL®coolant which will not damage
aluminum parts. If you use this coolant mixture,
you do not need to add anything else.
{CAUTION:
Adding only plain water to your cooling
system can be dangerous. Plain water, or
some other liquid such as alcohol, can boil
before the proper coolant mixture will. Your
vehicle’s coolant warning system is set for the
proper coolant mixture. With plain water or the
wrong mixture, your engine could get too hot
but you would not get the overheat warning.
Your engine could catch re and you or others
could be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®coolant.Notice:If you use an improper coolant mixture, your
engine could overheat and be badly damaged. The
repair cost would not be covered by your warranty.
Too much water in the mixture can freeze and crack
the engine, radiator, heater core, and other parts.
If you have to add coolant more than four times a year,
have your dealer/retailer check your cooling system.
Notice:If you use extra inhibitors and/or additives
in your vehicle’s cooling system, you could damage
your vehicle. Use only the proper mixture of the
engine coolant listed in this manual for the cooling
system. SeePart D: Recommended Fluids and
Lubricants on page 6-19for more information.
Checking Coolant
The vehicle must be on a level surface. When your
engine is cold, the coolant level should be at LOW,
or a little higher. When your engine is warm, the level
should be up to FULL, or a little higher.
SeeEngine Compartment Overview on page 5-12for
the location of the coolant recovery tank.
5-24

Adding Coolant
If you need more coolant, add the proper DEX-COOL®
coolant mixture at the coolant recovery tank, but be
careful not to spill it.
{CAUTION:
Turning the radiator pressure cap when the
engine and radiator are hot can allow steam
and scalding liquids to blow out and burn
you badly. With the coolant recovery tank,
you will almost never have to add coolant at
the radiator. Never turn the radiator pressure
cap — even a little — when the engine and
radiator are hot.
{CAUTION:
You can be burned if you spill coolant on hot
engine parts. Coolant contains ethylene glycol,
and it will burn if the engine parts are hot
enough. Do not spill coolant on a hot engine.
Occasionally check the coolant level in the radiator.
For information on how to add coolant to the radiator,
seeCooling System on page 5-28.
5-25

Radiator Pressure Cap
Notice:If the pressure cap is not tightly installed,
coolant loss and possible engine damage may occur.
Be sure the cap is properly and tightly secured.
SeeEngine Compartment Overview on page 5-12for
more information on location.
Engine Overheating
You will nd a coolant temperature gage on your
vehicle’s instrument panel. SeeEngine Coolant
Temperature Gage on page 3-35.
If Steam Is Coming From Your Engine
{CAUTION:
Steam from an overheated engine can burn
you badly, even if you just open the hood.
Stay away from the engine if you see or hear
steam coming from it. Just turn it off and get
everyone away from the vehicle until it cools
down. Wait until there is no sign of steam or
coolant before you open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch re.
You or others could be badly burned. Stop
your engine if it overheats, and get out of
the vehicle until the engine is cool.
Notice:If your engine catches re because you
keep driving with no coolant, your vehicle can
be badly damaged. The costly repairs would not
be covered by your warranty.
