Operating the engine with the air cleaner off can
cause you or others to be burned. The air cleaner
not only cleans the air, it stops flame

backfires,
you could be burned. Don’t drive with
it
off, and be careful working on the engine with
the air cleaner off.

into your engine, which will damage it. Always
have the air cleaner in place when you’re driving.
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:
0 In heavy city traffic where the outside temperature
0 In hilly or mountainous terrain.
0 When doing frequent trailer towing.
0 Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any
of these
conditions, the fluid and filter do not require change
until the message

may have to drive longer.
Checking the Fluid Level
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:

lower level. The fluid level must be in the
cross-hatched area.
6. If the fluid level is in the acceptable range, push
the dipstick back
in all the way. Replace the air
cleaner assembly.
How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind
of transaxle fluid to use. See “Recommended Fluids
and Lubricants”
in the Maintenance Schedule booklet.

Downloaded from www.Manualslib.com manuals search engine 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 ovegi’ll.

NOTICE:
We recommend you use only fluid labeled
DEXRON@-111, because fluid with that label
is
made especially for your automatic transaxle.
Damage caused by fluid other than DEXRON-I11
is not covered by your new vehicle warranty.
3. After adding fluid, recheck the fluid level as
described under “How
to Check.”
4. When the correct fluid level is obtained, push the
dipstick back
in all the way.
How to Reset Transaxle Fluid
Change Indicator:
Your vehicle is equipped with a transaxle fluid change
indicator.
A CHANGE TRANS FLUID message will
display
on the Driver Information Center (DIC) when
the powertrain computer determines that the transaxle
fluid needs to be changed or at each
100,000 miles
(160 000 km) interval, whichever occurs first. See your
Maintenance Schedule booklet for more information.
When this message appears, change
the transaxle fluid
and reset the transaxle fluid life indicator as follows:
1. Turn the ignition on but do not start the engine.
2. Press and hold the OFF and rear defog buttons on
the climate control system at the same time until
the TRANS FLUID RESET message appears on
the DIC.

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 “Engine
Overheating” in the Index.
A 50/50 mixture of water and DEX-COOL@
coolant will:
0 Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 “F (1 29°C).
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
0 Let the warning lights 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

Downloaded from www.Manualslib.com manuals search engine What to Use
Use a mixture of one-half clean water (preferably
distilled) and one-half
DEX-COOL” coolant which
won’t damage aluminum parts.
If you use this mixture.
you don’t need
to add anything else.
A CAUTION:
Adding only plain water to your cooling system
can be dangerous. Plain water, or some other liquid like 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 wouldn’t
get the overheat warning. Your engine could
catch fire and you or others could be burned.
Use a
50/50 mixture of clean water and
DEX-COOL@ coolant.
NOTICE:
If you use an improper coolant mixture, your
engine could overheat and be badly damaged. The repair cost wouldn’t 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 check your cooling system.
I NOTICE:
~~~~~
If you use the proper coolant, you don’t have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.

The surge tank is located next to the engine block on the
passenger's side
of the engine.
The cooling system is under a
lot of pressure when it
is hot. If the CHECK COOLANT LEVEL message
appears
on the Driver Information Center (DIC), you
will need to add coolant.
A CAUTION:
Turning the surge tank pressure cap when the
engine and radiator are hot can allow steam and
scalding liquids to blow out and burn
you badly.
Never turn the surge tank pressure cap
-- even a
little
-- when the engine and radiator are hot.
When your engine is cold. the coolant level should be at
the full cold mark, which
is 2.5 inches (6.4 cm) below
the base
of the fill neck. Use a flashlight as necessary to
see into the tank.
