Checking Things Under
the Hood
I
An electric fan under the hood can start up
and injure you even when the engine
is not
running. Keep hands, clothing and tools away
from any underhood electric fan. Things that
b n can get on hot engine parts
and start a fire. These include liquids like fuel,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber. You or
others could be burned. Be careful not to drop
or
spill things that will burn onto a hot engine.

OIL LEVEL
If the OIL LEVEL LOW
message appears
on the
DIC, or the CHECK
OIL LEVEL light appears
on the instrument cluster, it
means
YOU need to
check your engine oil level
right away.
For more information, see
Check Oil Level Light on
page
3-50 or DIG Warnings and Messages on
page 3-60.
You should check your engine oil level regularly; this is
an added reminder.

How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind of transaxle fluid
to use. See Part D:
Recommended Fluids and Lubricants on page 6-24.
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@-Ill, because fluid with that label is
made especially for your automatic transaxle.
Damage caused by fluid other than DEXRON@-Ill
is
not covered by your new vehicle warranty.
3. After adding fluid, recheck the fluid level as
described under “How to Check,” earlier in this
section.
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 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 on
page
5-29.
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.
4. When the correct fluid level is obtained, push the
dipstick back
in all the way.
5-26

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.
What to Use
Use a mixture of one-half clean, drinkable water and
one-half
DEX-COOL@ coolant which won’t damage
aluminum
parts. If you use this coolant mixture,
you don’t need to add anything else. 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 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,
drinkable water and
DEX-@SOL@ esslani.
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, neater core ana
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 don’t
have to add extra inhibitors or additives which claim
to improve the system. These can be harmful.
5-27

Checking Coolant
The engine coolant
recovery tank is located in
the engine compartment
on the passenger’s side of
the vehicle, near the windshield. See
Engine
Compartment Overview on
page
5-74 for more
information on location.
Adding Coolant
The vehicle must be on a level surface. When your
engine
is cold, the coolant level should be at the
FULL COLD mark or a little higher. When your engine is
warm, the level should be up to the FULL HOT mark
or a little higher.
If you need more coolant, add the proper DEX-COOL@
coolant mixture
at the coolant recovery tank, but be
careful not to spill it.
Turnin- :he rai tor pressure
~-2 w..,n 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.
5-28

1 -J can __ burned if you spill coolant -.I hot
engine parts. Coolant contains ethylene glycol,
and
it will burn if the engine parts are hot
enough. Don’t spill coolant on a hot engine.
~~ ~ ~~
Occasionally check the coolant level in the radiator.
For information on how to add coolant to the radiator,
see
Cooling System on page 5-32.
Radiator Pressure Cap
Notice: Your radiator cap is a pressure-type cap
and must be tightly installed to prevent coolant
loss
and possible engine damage from overheating.
Be sure the arrows on the cap line up with the
overflow tube on the radiator filler
neck.
See Engine Compartment Overview on page 5-14 for
more information on location.
Engine Overheating
You will find a coolant temperature gage or a DIC
warning message about a hot engine on your vehicle’s
instrument panel. See
Engine Coolant Temperature
Gage on page 3-45
and DIC Warnings and Messages
on page
3-60.
5-29

If Steam Is Coming From Your Engine
Steam from an overheated engine can ~ ~ rn
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 fire. 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 fire because you
keep driving with no coolant, your vehicle can
be badly damaged. The costly repairs would not be
covered by your warranty.
