Vehicle Care 10-15
Notice:Engine damage from
running the engine without
coolant is not covered by the
warranty.
Notice: Using coolant other than
DEX-COOL
®can cause premature
engine, heater core, or radiator
corrosion. In addition, the
engine coolant could require
changing sooner, at 50 000 km
(30,000 miles) or 24 months,
whichever occurs first.
Any repairs would not be
covered by the vehicle warranty.
Always use DEX-COOL
®
(silicate-free) coolant in the
vehicle.
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 five years
or 240 000 km (150,000 miles),
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 on page 10‑20.
A 50/50 mixture of clean, drinkable
water and DEX-COOL
®coolant will:
.Give freezing protection down
to −37°C (−34°F).
.Give boiling protection up to
129°C (265°F).
.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
®can cause premature
engine, heater core, or radiator
corrosion. In addition, the engine
coolant may require changing
sooner, at the first maintenance
service after each 30,000 miles
(50 000 km) or 24 months,
whichever occurs first. Any
repairs would not be covered by
the vehicle warranty. Always use
DEX‐COOL
®(silicate‐free) coolant
in the vehicle.

10-16 Vehicle Care
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.
{WARNING
Adding only plain water to the
cooling system can be
dangerous. Plain water, or some
other liquid such as alcohol, can
boil before the proper coolant
mixture will. The vehicle's coolant
warning system is set for the
proper coolant mixture. With plain
water or the wrong mixture, the
(Continued)
WARNING (Continued)
engine could get too hot but you
would not get the overheat
warning. The engine could catch
fire and you or others could be
burned. Use a 50/50 mixture of
clean, drinkable water and
DEX-COOL
®coolant.
Notice: If an improper coolant
mixture is used, the engine could
overheat and be badly damaged.
The repair cost would not be
covered by the vehicle 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 extra inhibitors and/or
additives are used in the vehicle's
cooling system, the vehicle
could be damaged. Use only the
proper mixture of the engine
coolant listed in this manual
for the cooling system.

Vehicle Care 10-17
Checking Coolant
The surge tank is located on the
driver side of the engine
compartment. SeeEngine
Compartment Overview
on
page 10‑6for more information
on location.
{WARNING
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.
The vehicle must be on a level
surface. When your engine is cold,
the coolant level should be between
the MIN and MAX lines. Adding Coolant
If you need more coolant, add the
proper DEX-COOL®coolant mixture
at the surge tank, but only when the
engine is cool. See below for
instructions on “How to Add Coolant
to the Coolant Surge Tank”.
{WARNING
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.
When replacing the pressure cap,
make sure it is hand-tight and
fully seated.

How to Add Coolant to the
Coolant Surge Tank
Notice:This vehicle has a
specific coolant fill procedure.
Failure to follow this procedure
could cause the engine to
overheat and be severely
damaged.
If you have not found a problem yet,
check to see if coolant is visible in
the surge tank. If coolant is visible
but the coolant level is not at
between the MIN and MAX lines,
add a 50/50 mixture of clean,
drinkable water and DEX-COOL
®
coolant at the coolant surge tank,
but be sure the cooling system,
including the coolant surge tank
pressure cap, is cool before you
do it. See Engine Coolant
on
page 10‑15for more information.
{WARNING
Steam and scalding liquids from a
hot cooling system can blow out
and burn you badly. They are
under pressure, and if you turn
the coolant surge tank pressure
cap —even a little —they can
come out at high speed. Never
turn the cap when the cooling
system, including the coolant
surge tank pressure cap, is hot.
Wait for the cooling system and
coolant surge tank pressure cap
to cool if you ever have to turn
the pressure cap.
{WARNING
Adding only plain water to the
cooling system can be
dangerous. Plain water, or some
other liquid such as alcohol, can
boil before the proper coolant
mixture will. The vehicle's coolant
warning system is set for the
proper coolant mixture. With plain
water or the wrong mixture, the
engine could get too hot but you
would not get the overheat
warning. The engine could catch
fire and you or others could be
burned. Use a 50/50 mixture of
clean, drinkable water and
DEX-COOL
®coolant.
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.

Vehicle Care 10-19
{WARNING
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.
1. You can remove the coolantsurge tank pressure cap when
the cooling system, including the
coolant surge tank pressure cap
and upper radiator hose, is no
longer hot.
Turn the pressure cap slowly
counterclockwise about
one-quarter of a turn. If you
hear a hiss, wait for that to stop. This will allow any pressure still
left to be vented out the
discharge hose.
2. Then keep turning the pressure cap slowly, and remove it.
3. Fill the coolant surge tank withthe proper DEX-COOL®coolant
mixture, to between the MIN and
MAX lines. 4. With the coolant surge tank
pressure cap off, start the
engine and let it run until you
can feel the upper radiator hose
getting hot. Watch out for the
engine cooling fan.
By this time, the coolant level
inside the coolant surge tank
may be lower. If the level is
lower, add more of the proper
DEX-COOL
®coolant mixture to
the coolant surge tank until the
level reaches between the MIN
and MAX lines.
5. Then replace the pressure cap. Be sure the pressure cap is
hand-tight.
Check the level in the surge tank
when the cooling system has
cooled down. If the coolant is not at
the proper level, repeat Steps 1
through 3 and reinstall the pressure
cap. If the coolant still is not at the
proper level when the system cools
down again, see your dealer/retailer.

Engine Overheating
There is a coolant temperature
warning light on your vehicle's
instrument panel. SeeEngine
Coolant Temperature Warning Light
on page 5‑21.
If Steam Is Coming From
Your Engine
{WARNING
Steam from an overheated engine
can cause serious injury, even if
the hood is opened just a little.
Stay away from the engine if
steam is seen or heard coming
from it. Just turn it off and get
everyone away from the vehicle
(Continued)
WARNING (Continued)
until it cools down. Wait until there
is no sign of steam or coolant
before opening the hood.
If driving continues when the
engine is overheated, the liquids
in it can catch fire. Someone
could get badly burned. Stop the
engine if it overheats, and get out
of the vehicle until the engine has
cooled.
Notice: Driving the vehicle when
there is no coolant in the coolant
overflow recovery bottle, can
badly damage the engine.
The costly repairs would not be
covered by the vehicle warranty.
If No Steam Is Coming From
The Engine
If there is an engine overheat
warning, but no steam can be seen
or heard, the problem may not be
too serious. Sometimes the engine
can get a little too hot when the
vehicle:
.Climbs a long hill on a hot day.
.Stops after high-speed driving.
.Idles for long periods in traffic.
.Tows a trailer.
If there is an overheat warning with
no sign of steam, try this for a
minute or so:
1. If there is an air conditioner and it is on, turn it off.
2. Turn on the heater to full hot at the highest fan speed and open
the windows as necessary.
3. Try to minimize engine load. If in a traffic jam, shift to N (Neutral);
otherwise, shift to the highest
gear possible while driving.

Vehicle Care 10-21
If the overheat warning is no longer
on, the vehicle can be driven. Just
to be safe, drive slower for about
ten minutes. If the warning does not
come back on, drive normally.
If the warning continues and the
vehicle is not stopped, pull over,
stop, and park the vehicle
right away.
If there is still no sign of steam, idle
the engine for three minutes while
parked. If the warning continues,
turn off the engine and get everyone
out of the vehicle until it cools down.
The decision may be made to not lift
the hood but to get service help
right away.Power Steering Fluid
SeeEngine Compartment Overviewon page 10‑6for reservoir location.
When to Check Power Steering
Fluid
Power steering fluid is used in all
vehicles with V6 engines. Vehicles
with the 4-cylinder engine have
electric power steering and does not
use power steering fluid.
It is not necessary to regularly
check power steering fluid unless
you suspect there is a leak in the
system or you hear an unusual
noise. A fluid loss in this system
could indicate a problem. Have the
system inspected and repaired.
How to Check Power Steering
Fluid
To check the power steering fluid,
do the following:
1. Turn the key off and let the
engine compartment cool down.
2. Remove engine oil fill cap.
3. Slide engine cover rearward and lift to remove.
4. Wipe the cap and the top of the reservoir clean.
5. Unscrew the cap and wipe the dipstick with a clean rag.
6. Replace the cap and completely tighten it.
7. Remove the cap again and look at the fluid level on the dipstick.
The fluid level should be within the
area indicated on the dipstick when
the engine is cold.

10-22 Vehicle Care
What to Use
To determine what kind of fluid to
use,Recommended Fluids and
Lubricants
on page 11‑7.
Always use the proper fluid.
Notice: Use of the incorrect fluid
may damage the vehicle and the
damages may not be covered by
the vehicle's warranty. Always
use the correct fluid listed in
Recommended Fluids and
Lubricants on page 11‑7.
Washer Fluid
What to Use
When you need windshield or rear
window washer fluid, be sure to
read the manufacturer's instructions
before use. If operating the vehicle
in an area where the temperature
can fall below freezing, use a fluid
that has sufficient protection against
freezing.
Adding Windshield Washer
Fluid
Open the cap with the washer
symbol on it. Add washer fluid
until the tank is full. See Engine
Compartment Overview
on
page 10‑6for reservoir location. Notice:
.When using concentrated
washer fluid, follow the
manufacturer's instructions
for adding water.
.Do not mix water with
ready-to-use washer fluid.
Water can cause the solution
to freeze and damage your
washer fluid tank and other
parts of the washer system.
Also, water does not clean as
well as washer fluid.
.Fill the washer fluid tank
only three-quarters full when
it is very cold. This allows
for fluid expansion if
freezing occurs, which could
damage the tank if it is
completely full.
.Do not use engine coolant
(antifreeze) in your
windshield washer. It can
damage the vehicle's
windshield washer system
and paint.
