Doing Your Own
Service Work
{WARNING
You can be injured and the
vehicle could be damaged if you
try to do service work on a vehicle
without knowing enough about it.
.Be sure you have sufficient
knowledge, experience,
the proper replacement
parts, and tools before
attempting any vehicle
maintenance task.(Continued)
WARNING (Continued)
.Be sure to use the proper
nuts, bolts, and other
fasteners. English and metric
fasteners can be easily
confused. If the wrong
fasteners are used, parts can
later break or fall off. You
could be hurt. If doing some of your own service
work, use the proper service
manual. It tells you much more
about how to service the vehicle
than this manual can. To order the
proper service manual, see
Service
Publications Ordering Information
on
page 12‑12.
This vehicle has an airbag system.
Before attempting to do your own
service work, see Airbag System
Check on page 2‑40.
Keep a record with all parts receipts
and list the mileage and the date of
any service work performed. See
Maintenance Records
on
page 10‑10.

Vehicle Care 9-13
What to Do with Used Oil
Used engine oil contains elements
that can be unhealthy for your skin
and could even cause cancer. Do
not let used oil stay on your skin.
Clean your skin and nails with soap
and water, or a good hand cleaner.
Wash or properly dispose of clothing
or rags. See the manufacturer's
warnings about the use and
disposal of oil products.
Used oil can be a threat to the
environment. If you change your
own oil, be sure to drain all the oil
from the filter before disposal. Never
dispose of oil by putting it in the
trash, pouring it on the ground, into
sewers, or into streams or bodies of
water. Recycle it by taking it to a
place that collects used oil.
Automatic Transmission
Fluid
How to Check Automatic
Transmission Fluid
It is not necessary to check
the transmission fluid level.
A transmission fluid leak is the
only reason for fluid loss. If a leak
occurs, take the vehicle to your
dealer/retailer service department
and have it repaired as soon as
possible.
There is a special procedure for
checking and changing the
transmission fluid. Because this
procedure is difficult, this should be
done at your dealer/retailer service
department. Contact your dealer/
retailer for additional information or
the procedure can be found in the
service manual. To purchase a
service manual, seeService
Publications Ordering Information
on
page 12‑12. Change the fluid and filter at the
intervals listed in
Scheduled
Maintenance
on page 10‑2, and be
sure to use the fluid listed in
Recommended Fluids and
Lubricants on page 10‑7.
Engine Air Cleaner/Filter
See Engine Compartment Overviewon page 9‑6
When to Inspect the Engine Air
Cleaner/Filter
Inspect the air cleaner/filter at the
Maintenance IIintervals and replace
it at the first oil change after each
83 000 km (50,000 mile) interval.
See Scheduled Maintenance
on
page 10‑2

Vehicle Care 9-15
{WARNING
Operating the engine with the air
cleaner/filter off can cause you or
others to be burned. The air
cleaner not only cleans the air; it
helps to stop flames if the engine
backfires. Use caution when
working on the engine and do not
drive with the air cleaner/filter off.
Notice: If the air cleaner/filter is
off, dirt can easily get into the
engine, which could damage it.
Always have the air cleaner/filter
in place when you are driving.
Cooling System
2.4L L4 Engine
A. Engine Cooling Fan
B. Engine Coolant Surge Tank and Pressure Cap
3.0L V6 Engine
A. Engine Cooling Fans
B. Engine Coolant Surge Tank and Pressure Cap
{WARNING
An electric engine cooling fan
under the hood can start up even
when the engine is not running
and can cause injury. Keep
hands, clothing, and tools away
from any underhood electric fan.

9-16 Vehicle Care
If the coolant inside the coolant
surge tank is boiling, do not do
anything else until it cools down.
The vehicle should be parked on a
level surface.
The coolant level should be at the
COLD FILL line. If it is not, you may
have a leak at the radiator hoses,
heater hoses, radiator, water pump,
or somewhere else in the cooling
system.
{WARNING
Heater and radiator hoses, and
other engine parts, can be very
hot. Do not touch them. If you do,
you can be burned.
Do not run the engine if there is a
leak. If you run the engine, it
could lose all coolant. That could
cause an engine fire, and you
could be burned. Get any leak
fixed before you drive the vehicle.If there seems to be no leak,
with the engine on, check to see
if the electric engine cooling
fan is running. If the engine is
overheating, the fan should be
running. If it is not, your vehicle
needs service. Turn off the engine.
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 the vehicle
is filled with DEX-COOL®engine
coolant. This coolant is designed to
remain in the vehicle for five years
or 240 000 km (150,000 miles),
whichever occurs first.
The following explains the cooling
system and how to check and add
coolant when it is low. If there is a
problem with engine overheating,
see Engine Overheating
on
page 9‑20.

Vehicle Care 9-17
What to Use
{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.Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®
coolant. If using this mixture,
nothing else needs to be added.
This mixture:
.Gives freezing protection down
to
−37°C (−34°F), outside
temperature.
.Gives boiling protection up to
129°C (265°F), engine
temperature.
.Protects against rust and
corrosion.
.Will not damage aluminum parts.
.Helps keep the proper engine
temperature.
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.
Checking Coolant
The vehicle must be on a level
surface when checking the coolant
level.
Check to see if coolant is visible in
the coolant surge tank. If the coolant
inside the coolant surge tank is
boiling, do not do anything else until
it cools down. If coolant is visible
but the coolant level is not at or
above the COLD FILL line, add a
50/50 mixture of clean, drinkable
water and DEX-COOL
®coolant at
the coolant surge tank, but be sure
the cooling system is cool before
this is done. See Cooling System
on
page 9‑15for more information.
The coolant surge tank is located in
the engine compartment on the
driver side of the vehicle. See
Engine Compartment Overview
on
page 9‑6for more information on
location.

9-18 Vehicle Care
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 coolant surge tank. If coolant
is visible but the coolant level is
not at the COLD FILL line, 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
Overheating
on page 9‑20for 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
(Continued)
WARNING (Continued)
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.
{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.
