Engine OilChecking Engine Oil
It is a good idea to check your engine oil
every time you get fuel. In order to get an
accurate reading, the oil must be warm
and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow
loop. Refer to “Engine Compartment Over-
view” in this section for the location of the
engine oil dipstick.
1) Turn off the engine and give the oil sev-
eral minutes to drain back into the oil
pan. If you do not do this, the oil dip-
stick might not show the actual level.
2) Pull out the dipstick and clean it with a
paper towel or cloth, then push it back
in all the way. Remove it again, keeping
the tip down, and check the level.When to Add Engine Oil
830434
If the oil is below the cross-hatched area at
the tip of the dipstick, you need to add at
least one quart/liter of oil. But you must
use the right kind. This section explains
what kind of oil to use. For engine oil
crankcase capacity, refer to “Capacities
and Specifications” in this section.
824596
SAE 5W-30 may not appear on all caps.
Refer to “Engine Compartment Overview”
in this section for the location of the engine
oil fill cap.
Be sure to add enough oil to put the level
somewhere in the proper operating range
in the cross-hatched area. Push the dip-
stick all the way back in when you are
through.
CAUTION
Do not add too much oil. If the engine
has so much oil that the oil level gets
above the cross-hatched area that
shows the proper operating range,
the engine could be damaged.

What Kind of Engine Oil to Use
Recommended SAE viscosity grade
engine oils

Look for two things:
GM6094M
Your vehicle’s engine requires oil meet-
ing standard GM6094M. Look for and
use only an oil that meets standard
GM6094M.
SAE 5W-30
As shown in the viscosity chart, SAE
5W-30 is best for your vehicle.
These numbers on an oil container show
its viscosity, or thickness. Do not use
other viscosity oils such as SAE 20W-
50.
808500
Oils meeting these requirements should
also have the starburst symbol on the con-
tainer. This symbol indicates that the oil
has been certified by the American Petro-
leum Institute (API).
Look for this information on the oil con-
tainer, and use only those oils that are
identified as meeting standard GM6094M
and have the starburst symbol on the front
of the oil container.If you are in an area of extreme cold,
where the temperature falls below –20°F
(–29°C), it is recommended that you use
either an SAE 5W-30 synthetic oil or an
SAE 0W-30 oil. Both provide easier cold
starting and better protection for the
engine at extremely low temperatures.
Engine Oil Additives
Do not add anything to the oil. The recom-
mended oils with the starburst symbol that
meet standard GM6094M are all you need
for good performance and engine protec-
tion.
Engine Oil Life SystemWhen to Change Engine Oil
Your vehicle has a computer system that
lets you know when to change the engine
oil and filter. This is based on engine revo-
lutions and engine temperature, and not on
mileage. Based on driving conditions, the
mileage at which an oil change will be indi-
cated can vary considerably. For the oil life

system to work properly, you must reset
the system every time the oil is changed.
When the system has calculated that oil
life has been diminished, it will indicate
that an oil change is necessary. A change
engine oil light and a CHANGE ENGINE
OIL SOON message will come on. Refer to
“Change Engine Oil Light” in “Warning
Lights, Gages, and Indicators” in the
“Instrument Panel” section and “DIC Warn-
ings and Messages” in “Driver Information
Center (DIC)” in the “Instrument Panel”
section. Change your oil as soon as possi-
ble within the next 600 miles (1000 km). It
is possible that, if you are driving under the
best conditions, the oil life system may not
indicate that an oil change is necessary for
over a year. However, your engine oil and
filter must be changed at least once a year
and at this time the system must be reset.
Your dealer has trained service people
who will perform this work and reset the
system. It is also important to check your
oil regularly and keep it at the proper level.
If the system is ever reset accidentally, you
must change your oil at 3000 miles (5000
km) since your last oil change. Remember
to reset the oil life system whenever the oil
is changed.
How to Reset the Engine Oil Life Sys-
tem
The Engine Oil Life System calculates
when to change your engine oil and filter
based on vehicle use. Anytime your oil ischanged, reset the system so it can calcu-
late when the next oil change is required. If
a situation occurs where you change your
oil prior to a change engine oil light or
CHANGE ENGINE OIL SOON message
being turned on, reset the system.
1) Turn the ignition key to RUN with the
engine off.
2) Fully press and release the accelerator
pedal three times within five seconds.
The change engine oil light will flash
while the system is resetting.
3) When the light stops flashing, turn the
key to LOCK.
If the light or message comes back on and
stays on when you start your vehicle, the
engine oil life system has not reset.
Repeat the procedure.
What to Do with Used Oil
Used engine oil contains certain elements
that may be unhealthy for your skin and
could even cause cancer. Do not let used
oil stay on your skin for very long. Clean
your skin and nails with soap and water, or
a good hand cleaner. Wash or properly
dispose of clothing or rags containing used
engine oil. See the manufacturer’s warn-
ings about the use and disposal of oil prod-
ucts.
Used oil can be a threat to the environ-
ment. If you change your own oil, be sure
to drain all the oil from the filter before dis-
posal. Never dispose of oil by putting it inthe trash, pouring it on the ground, into
sewers, or into streams or bodies of water.
Instead, recycle it by taking it to a place
that collects used oil. If you have a prob-
lem properly disposing of your used oil,
ask your dealer, a service station, or a
local recycling center for help.
Engine Air Cleaner/FilterThe engine air cleaner/filter is located in
the engine compartment on the passen-
ger’s side of the vehicle. Refer to “Engine
Compartment Overview” in this section for
more information on location.
When to Inspect the Engine Air Cleaner/
Filter
Inspect the air cleaner/filter at the Mainte-
nance II intervals and replace it at the first
oil change after each 50000 mile (83000
km) interval. Refer to “Scheduled Mainte-
nance” in “Maintenance Schedule” in the
“Maintenance Schedule” section for more
information. If you are driving in dusty/dirty
conditions, inspect the filter at each engine
oil change.
How to Inspect the Engine Air Cleaner/
Filter
To inspect the air cleaner/filter remove the
filter from the vehicle and lightly shake the
filter to release loose dust and dirt. If the fil-
ter remains caked with dirt, a new filter is
required.

Automatic Transaxle FluidIt is not necessary to check the transaxle
fluid level. A transaxle fluid leak is the only
reason for fluid loss. If a leak occurs, take
your vehicle to the dealership service
department and have it repaired as soon
as possible.
Change the fluid at the intervals listed in
“Additional Required Services” in “Mainte-
nance Schedule” in the “Maintenance
Schedule” section, and be sure to use the
transaxle fluid listed in “Recommended
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. If
it is not there and the engine back-
fires, you could be burned. Do not
drive with it off, and be careful work-
ing on the engine with the air cleaner/
filter off.
CAUTION
If the air cleaner/filter is off, a back-
fire can cause a damaging engine
fire. And, dirt can easily get into your
engine, which will damage it. Always
have the air cleaner/filter in place
when you are driving.

Fluids and Lubricants” in “Maintenance
Schedule” in the “Maintenance Schedule”
section.Engine CoolantThe cooling system in your vehicle is filled
with DEX-COOL
® engine coolant. This
coolant is designed to remain in your vehi-
cle for five 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 overheat-
ing, refer to “Engine Overheating” in this
section.
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 tempera-
ture.
Let the warning lights and gages work as
they should.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.
CAUTION
Use of the incorrect automatic tran-
saxle fluid may damage your vehicle,
and the damages may not be covered
by your warranty. Always use the
automatic transaxle fluid listed in
“Recommended Fluids and Lubri-
cants” in “Maintenance Schedule” in
the “Maintenance Schedule” section.
CAUTION
Using coolant other than DEX-COOL
®
may cause premature engine, heater
core, or radiator corrosion. In addi-
tion, the engine coolant may require
changing sooner, at the first mainte-
nance service after each 30000 miles
(50000 km) or 24 months, whichever
occurs first. Any repairs would not be
covered by your warranty. Always
use DEX-COOL
® (silicate-free) cool-
ant in your vehicle.
WARNING
Adding only plain water to your cool-
ing 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 fire and you
or others could be burned. Use a 50/
50 mixture of clean, drinkable water
and DEX-COOL
® coolant.
CAUTION
If you use an improper coolant mix-
ture, your engine could overheat and
be badly damaged. The repair cost
would not be covered by your war-
ranty. Too much water in the mixture
can freeze and crack the engine, radi-
ator, heater core, and other parts.
5-12 SERVICE AND APPEARANCE CARE
78J00-03E
If you have to add coolant more than four
times a year, have your dealer check your
cooling system.
Checking Coolant
1631523
The surge tank is located on the driver’s
side of the engine compartment. Refer to“Engine Compartment Overview” in this
section for more information on location.
The vehicle must be on a level surface.
When your engine is cold, the coolant level
should be at the COLD FILL line. When
your engine is warm, the level should be at
the COLD FILL line or a little higher.
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.
When replacing the pressure cap, make
sure it is hand-tight and fully seated.
Engine OverheatingThere is a coolant temperature gage and a
warning light on the instrument panel clus-
ter that indicate an overheated engine con-
dition. Refer to “Engine Coolant
Temperature Gage” and “Engine Coolant
Temperature Warning Light” in “Warning
Lights, Gages, and Indicators” in the
“Instrument Panel” section for more infor-
mation.
If Steam Is Coming From Your Engine
CAUTION
If you use extra inhibitors and/or
additives in your vehicle’s cooling
system, you could damage your vehi-
cle. Use only the proper mixture of
the engine coolant listed in this man-
ual for the cooling system. Refer to
“Recommended Fluids and Lubri-
cants” in “Maintenance Schedule” in
the “Maintenance Schedule” section
for more information.
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.
WARNING
You can be burned if you spill cool-
ant on hot engine parts. Coolant con-
tains ethylene glycol, and it will burn
if the engine parts are hot enough. Do
not spill coolant on a hot engine.
WARNING
Steam from an overheated engine
can burn you badly, even if you just
open the hood. Stay away from the
engine if you see or hear steam com-
ing from it. Turn it off and get every-
one 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 the vehicles
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.
Refer to “Overheated Engine Protec-
tion Operating Mode” in this section
for information on driving to a safe
place in an emergency.

If No Steam Is Coming From Your
Engine
If you get an engine overheat warning, but
see or hear no steam, the problem may not
be too serious. Sometimes the engine can
get a little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning with no
sign of steam, try this for a minute or so:
1) In heavy traffic, let the engine idle in
NEUTRAL (N) while stopped. If it is
safe to do so, pull off the road, shift to
PARK (P) or NEUTRAL (N) and let the
engine idle.
2) Set the climate controls to the highest
heat setting and fan speed and open
the windows as necessary.If you no longer have the overheat warn-
ing, you can drive. Just to be safe, drive
slower for about 10 minutes. If the warning
does not come back on, you can drive nor-
mally.
If the warning continues and you have not
stopped, pull over, stop, and park your
vehicle right away.
If there is still no sign of steam, you can
idle the engine for three minutes while you
are parked. If you still have the warning,
turn off the engine and get everyone out of
the vehicle until it cools down. Also, see
“Overheated Engine Protection Operating
Mode” later in this section.
You may decide not to lift the hood but to
get service help right away.
Overheated Engine Protection Operat-
ing Mode
This emergency operating mode allows
your vehicle to be driven to a safe place in
an emergency situation. If an overheated
engine condition exists, an overheat pro-
tection mode which alternates firing groups
of cylinders helps prevent engine damage.
In this mode, you will notice a significant
loss in power and engine performance.
The engine coolant temperature warning
light on the instrument panel will come on
to indicate the vehicle has entered over-
heated engine protection operating mode.
The temperature gage will also indicate an
overheat condition exists. Drivingextended miles (km) and/or towing a trailer
in the overheat protection mode should be
avoided.
Cooling SystemWhen you decide it is safe to lift the hood,
here is what you will see:

A. Electric Engine Cooling Fans
B. Coolant Recovery Tank
CAUTION
If your engine catches fire because
you keep driving with no coolant,
your vehicle can be badly damaged.
The costly repairs would not be cov-
ered by your warranty. Refer to
“Overheated Engine Protection Oper-
ating Mode” in this section for infor-
mation on driving to a safe place in
an emergency.
CAUTION
After driving in the overheated
engine protection operating mode, to
avoid engine damage, allow the
engine to cool before attempting any
repair. The engine oil will be severely
degraded. Repair the cause of cool-
ant loss, change the oil and reset the
oil life system. Refer to “Engine Oil”
in this section.

C. Pressure Cap
If the coolant inside the coolant recovery
tank is boiling, do not do anything else until
it cools down. The vehicle should be
parked on a level surface.
When the engine is cold, the coolant level
should be at or above the cold fill line on
the coolant recovery tank. If it is not, there
may be a leak at the pressure cap or in the
radiator hoses, heater hoses, radiator,
water pump, or somewhere else in the
cooling system.If there seems to be no leak, with the
engine on, check to see if the electric
engine cooling fans are running. If the
engine is overheating, the fans should be
running. If the fans are not running, the
vehicle needs service.How to Add Coolant to the Coolant
Recovery Tank
If you have not found a problem yet, but
the coolant level is not at the cold fill line,
add a 50/50 mixture of clean, drinkable
water and DEX-COOL
® engine coolant at
the coolant recovery tank. Refer to “Engine
Coolant” in this section for more informa-
tion.
WARNING
An electric engine cooling fan under
the hood can start up even when the
engine is not running and can injure
you. Keep hands, clothing, and tools
away from any underhood electric
fan.
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.
CAUTION
Engine damage from running your
engine without coolant is not covered
by your warranty. Refer to “Over-
heated Engine Protection Operating
Mode” in this section for information
on driving to a safe place in an emer-
gency.
CAUTION
Using coolant other than DEX-COOL
®
may cause premature engine, heater
core, or radiator corrosion. In addi-
tion, the engine coolant could require
changing sooner, at 30000 miles
(50000 km) or 24 months, whichever
occurs first. Any repairs would not be
covered by your warranty. Always
use DEX-COOL
® (silicate-free) cool-
ant in your vehicle.
WARNING
Adding only plain water to your cool-
ing 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 fire and you
or others could be burned. Use a 50/
50 mixture of clean, drinkable water
and DEX-COOL
® coolant.
CAUTION
In cold weather, water can freeze and
crack the engine, radiator, heater
core and other parts. Use the recom-
mended coolant and the proper cool-
ant mixture.
