How to Add Fluid Automatic Transaxle
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 cross-hatched 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 over®ll.
Notice:Use of automatic transaxle ¯uid labeled
other than DEXRONž-III may damage your vehicle,
and the damages may not be covered by your
warranty. Always use DEXRON
ž-III labeled automatic
transaxle ¯uid.
3. After adding ¯uid, recheck the ¯uid level as
described under ªHow to Check Automatic
Transaxle Fluidº.
4. When the correct ¯uid level is obtained, push the
dipstick back in all the way.
Engine Coolant
The cooling system in your vehicle is ®lled with
DEX-COOLžengine coolant. This coolant is designed
to remain in your vehicle for 5 years or 150,000 miles
(240 000 km), whichever occurs ®rst, if you add
only DEX-COOL
žextended 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
on page 5-25.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
žcoolant will:
·Give freezing protection down to-34ÉF (-37ÉC)
·Give boiling protection up to 265ÉF (129ÉC)
·Protect against rust and corrosion
·Help keep the proper engine temperature
·Let the warning messages and gages work
as they should
Notice:Using coolant other than DEX-COOLžmay
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
ž(silicate-free) coolant in your vehicle.
5-22

What Engine Coolant to Use
Use a mixture of one-halfclean, drinkable waterand
one-half DEX-COOLžcoolant 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
žcoolant.
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 check your cooling system.
Notice:If you use the proper coolant, you do not
have to add extra inhibitors or additives which claim
to improve the system. These can be harmful.
5-23

How to Add Coolant to the Coolant
Recovery Tank
If you have not found a problem yet, but the coolant
level is not at or above the FULL COLD mark, add
a 50/50 mixture of
clean, drinkable waterand
DEX-COOLžengine coolant at the coolant recovery
tank. SeeEngine Coolant on page 5-22for more
information.
{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
žcoolant.
Notice:In cold weather, water can freeze and crack
the engine, radiator, heater core and other parts.
Use the recommended coolant and the proper
coolant mixture.
{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.
